APPRAISAL OF A ROAD IMPROVEMIENTAND MAINTENANCEPROJECT

SUMMARY AND CONCLUSIONS

i. The road system in Jamaica is generally adequate in extent; in recent years, however, maintenance has not kept pace with the needs of the system, particularlythose of the paved roads. Moreover, some of the paved roads are reaching the point whiere,with increasing traffic, strengthening, is becoming necessary.

ii. Road maintenanceand the institution-responsiblefor it have been studied in recent years, first in 1968 as part of a countrywide transporta- tion survey carried out by the Canadian consultants Lamarre Valois Interna- tional Ltd. (LVI), with financing by the Canadian InternationalDevelopment Agency (CIDA), and then in 1972 by the UK consultantsT.P. O'Sullivan and Partners (TPOS) in a study financed by the United Nations Development Pro- gram (UNDP), for which the Bank was executing agency. The CIDA-financed study recommended,inter alia, a major resurfacingprogram for paved roads to prevent further deteriorationof pavements, and improvement in the struc- ture and procedures of the road maintenance organization. The UNDP-financed study went a step further, recommendingspecific road improvement and mainte- nance, and made definite suggestionsfor improvementof the maintenance or- ganization. iii. The proposed project is based largely on the results of this latter study and has, therefore, a twofold thrust - physical improvement of the road network, and organizationalimprovement of the road maintenance organ- ization. As regards road improvement,the project envisages strengthening of about 440 miles of major roads with asphaltic overlay and resealing of a further 250 miles on which the pavements, although not yet overstressed, would deteriorate and require costly rehabilitationwithout this treatment. No major improvementof the geometric features of the road network are en- visaged, but particularlybad features, such as very sharp bends and dis- torted cross-sectionprofiles, would be improved in conjunctionwith these works. iv. Improvement of the maintenance organization envisaged comprises (a) a change in line management structure which would have the effect of introducing professionalengineers into the maintenance organization; (b) introductionof rational costing and better planning of maintenance optra- tions; and (c) a modest increase in the management staff of the organiza- tion. Also under this heading, thieproject would provide equipment for routine maintenance operations and a small quantity of tools for the work- shops which service such equipment. A substantial provision for technical assistance is included to help implement all aspects of the project. - 2ii - v. Execution would be the responsibility of the Ministry of Works (MOW) and would extend over a period of about five years. This period is determinedi largely by the time required for the civil works; these, in turn, have been spread out to reduce the load on budgetary funds to an acceptable leve' and to help ensure a more even workload on the resources of the iMinistryand the contracting industry. vi. The asphaltic overlay would be procured by international competi- tive bidding, following the Bank's guidelines, in two tranches of about US$3 million each. There would be a number of contracts in each tranche, but the work would be packaged, and bidders would have the opportunity to bid for any part or for thiewhole package. The asphaltic resealing would be bid in a similar manner, but, since the work is rather scattered and small scale, it would probably be unattractive to firms not already established in the couni- try; this work would therefore be advertised only in Jamaica. The road main- tenance equipment would be procured by international competitive bidding, following international advertising. vii. The project would benefit all parts of the cotuntry. The asphaltic overlay would be applied primarily to the circumferential road and a few major cross-country routes - these constitute the most heavily trafficked roads in the country. The resealing work and the improvement of day-to-day maintenance would have its effect primarily on the secondary road network. Not all of the benefits are readily quantifiable, and the economic evalua- tion concentrates on the proposed investment in asphaltic overlay (represent- ing over 40,% of project costs). For the overlav, the econoraic return is in excess of 50%; even if significant factors in the evaluation are varied to represent more pessimistic values, the economic return is still acceptable. For the resealing, on the assumption that failure would take place in four years' time if the pavements were not resealed in the near future, the economic return on the proposed resealing is conservatively estimated at about 19%. For the equipment included in the project, a very modest re- duction (of the order of a few percent) in vehicle operating costs result- ing from the use of this equipment would be sufficient to provide an economic return of 10% on the investment in equipment. Together these three items -- overlay, resealing and provision of equipment -- account for over 90% of project cost. viii. The project is estimated to cost US$17.3 million equivalent, with a foreign exchange component of US$9.3 million. The project would provide a satisfactory basis for a Bank loan to cover this foreign exchange component for a term of 15 years, including a five-year period of grace. JAMAICA

APPRAISAL OF A ROAD IMPROVEMENTAND MTAINTENANCEPROJECT

1. INTRODUCTIGN

1.01 The Government of Jamaica has requested the Bank to help finance a project comprisingroad improvementand maintenance,institutional improve- ments and the provision of technicalassistance and equipment. This would be the second Bank-financedhighway project in Jamaica. The first (Loan 408-JM, US$5.5 million, 1965) consistedof detailed engineering,construction (to four-lanestandards) and supervisionof the Kingston-SpanishTown Road and the Moneague-CrescentPark road, totaling 19 miles. Initially, the proj- ect also included constructionof the Spanish Town-Bog lWalkroad (8 miles) but this, with the Bank's approval,was subsequentlydeleted because of increased costs. Execution of the projectwas delayed due to difficulties in right-of-way acquisition,unsatisfactory performance of subcontractors, relocationof public utilitiesano inter-unionlabor disputes resulting in abandonmentof work by the contractorafter 90% completion,and his claim of frustrationof contract. The work was resumed on force account basis and is now complete. The loan is fully disbursed.

1.02 In 1968, the Government,with financingfrom the Canadian InternationalDevelopment Agency (CIDA),appointed the Canadian firm of Lamarre Valois InternationalLtd. (LVI) to carry out a countrywidetrans- portation survey to (a) establish and analyze costs of transportationby rail, road, coastal shipping and air; (b) examine the capital investment proposed in each mode over the next 10 years; and (c) project capital and recurrent costs through 1979, recommenidingappropriate policies and measures for the most economical developmentof the country's transportationsystem during that period. LVI's report was issued in June 1970; the main recom- mendations relating to roads were that: (a) a major resurfacingprogram of paved roads should be undertaken to prevent further deteriorationof pave- ments and to reduce road-users'operating costs; (b) early construction/re- constructionof certain high-priorityroads identifiedin the report should be undertaken and (c) the structure and procedures of the road maintenance organizationshould be improved.

1.03 Acting on these recommendations,the Government,in 1971, commissionedLVI, again financed by CIDA, to carry out feasibilitystudies on about 320 miles of high-priorityroads, and detailed engineeringon 60 miles of arterial roads and 40 miles of secondarymain and Parish roads. This work will be completed in 1973, and the Government is expected to pro- pose reconstructionof some 30 miles of the arterial roads as the main element of a third Bank-financedhighway project inc]utdedin the lending program of the fiscal year 1974.

1.04 Acting on the LVI recommendationsrelating specificallyto the road resurfacingprogram and improvementof maintenance,the Government, in 1972, retained the UK consultantsT.P. O'Sullivan and Partners (TPOS) to carry out a road maintenance study; the study was financed in part by the United Nations Development Program (UNDP), and the Bank acted as executing agency. TPOS submitted its draft final report in November 1972; its recom- raendations formed the basis for appraisal of the project now proposed.

1.05 The project was appraised by Mr. W. Sikorski (Engineer) and Mtiss I. Pastor (Economist) in December 1972. The report has been edited by Miss V. Foster.

2. BACKGROUND

A. The Country and its Economy

2.01 Jamaica, the third largest island of the Caribbean, has an area of 4,410 square miles, its greatest length (east-west) being 146 miles and its greatest width (north-south) 51 miles. A mountain ridge about 2,500 feet high runs east-west, separating the island into northern and southern coastal areas. The island's natural resources include bauxite and other mineral deposits scattered in various locations in the central area; a plea- sant tropical climate and beaches suitable for tourism, primarily along the north coast; fertile soils for agriculture; and fishing and forest reserves. Jamaica's population of about two million has grown in the last 12 years at a net annual rate (allowing for migration) of about 1.5%. Its high population density of about 460 persons per square mile is surpassed only by Trinidad and Tobago among the Latin American and Caribbean countries. Kingston, the capital, situated on the southern coast, is the main market for the country's agricultural produce and imported goods. Montego Bay, on the north coast, is the most important tourist resort.

2.02 The per capita GNP of Jamaica is currently about US$690. In real terms, the growth rate of GDP is estimated to have reached about 5% p.a. over the last five years. The most important single contributor to the rapid growth of the economy is the mining sector 1/, which accounted for about 17% of GDP in 1971. The other leading contributors are manufacturing, agriculture, construction and tourism. The level of agricultural output in recent years has been variable, but Government expects that, following the implementation of a major investment program, it will stabilize in com- ing years at a high level and that, considering also the output of substan- tial investments in mining, increases in industrialization and the projected expansion in tourism, a growth in GDP of 6% p.a. in real terms would be attainable over the next few years.

1/ Jamaica is the world's largest producer of bauxite; it supplies about 42% of the raw material needs for the aluminum industry of North America, which in turn produces 60% of the world's aluminum output. - 3 -

2.03 In spite of Jamaica's satisfactorygrowth rate in the past years, unemploymentremains high at about 16% of the labor force. The high level of unemploymentis explained by the age distributionof the labor force (biased toward the younger age groups), the low rate of growth of the agri- cultural sector (the traditionallabor-intensive sector) and the high propor- tion of unskilled labor among the unemployed.

B. The Transport Sector

(i) General

2.04 Jamaica's transportsystem is generally adequate in extent, although not always in conditionor capacity;most of the population centers, productive areas, and ports are well served. The system consists of about 10,000 miles of arterial and secondary main (togethercalled "public") roads and Parish roads 1/, a 200-mile Government-ownedrailway, a few miles of private railway, four airports (two of them international),13 ports, and some petroleum products pipelines. In general, because of the island's rel- atively small size, the transportsystem is characterizedby short average hauls and trip lengths. Although there are no readily available statistics on the modal distributionof land traffic within the system, all evidence demonstratesthat an overwhelmingproportion, particularly of passenger traf- fic, is carried by road. This pattern of allocation between modes is likely to continue over the next 10 years or so.

(ii) Roads

2.05 Details of the road system and its administrationare given in Chapter 3.

(iii) Railways

2.06 The public railway in Jamaica is run by the Jamaica Railways Corporation (JRC), which is responsible to the Minister of Public Utilities, Communicationsand Transport. The system consistq of 205 miles, most of it built in the latter half of the 19th century. The main trunk line (112 miles) provides access to the country'smain mining and agriculturalareas and connects eight of the largest towns of the island. There are private lines owned by the bauxite mining companies. The railway system primarily serves the bauxite and alumina industry and a passenger demand; it carries only a small volume of general cargo. Railway operations, in general, are costly because of the relatively short hauls and the island's rugged topo- graphy.

1/ The administrativeunit of Jamaica is the "Parish" (of which there are 13). The Parish roads are also "public" roads in the normal sense (Table 1). - 4 -

2.07 JRC's freight traffic in 1971 was about 3.1 million tons or 83.6 million ton-km, of which over 98% was bauxite, alumina, or material associated with the industry. With the expansion of mining, this traffic grew at an average of 7% p.a. between 1966 and 1971. Other commodities (mostlyagricultural) have increasinglybeen diverted to road--sincefor non-bulk commodities,road transport offers a cheaper service than does the railway--withthe result that less than 40,000 tons of non-mining traffic were carried in 1971. The average haul of freight traffic remained broadly constant at 27 miles between 1966 and 1971. Total passengers carried were about 1.2 million in 1966 and 1 million in 1971, but total passenger miles increased during this period from 35.7 million to 39.5 million. The average passenger journey thus increased from 29 to 39 miles. This is attributable to more trips being taken between Kingston and Montego Bay, on which section about 70% of all passenger trips take place.

2.08 The 1970 Jamaican TransportationSurvey (para. 1.02) recommended,. as first priority, that the railway's rates and fares should be revised to help solve its deficit position, and that uneconomic lines should be aban- doned, or, alternatively,that the Government should provide grants to cover the cost of "social" services provided by the railway. The Government has since increased its contract rates, and they now probably cover the capital and operating costs, including overheads, of moving the mining traffic. In addition, in 1972, the Frankfield-MayPen line, one of the uneconomic lines, was closed. Most of the loss of JRC (about J$ 500,000 p.a.) is on lines not connected with the mining industry and, in fact, most of the loss is incurred on the line to Port Antonio. However, this line serves many poor areas, and the Minister of Public Utilities, Communicationsand Transport is reluctant to deprive them of the service.

(iv) Air Transport

2.09 Jamaica has two internationalairports, one at Kingston and one at Montego Bay, served by some 12 foreign airlines and by the national carrier, Air Jamaica. Internal flights between these and two domestic airports at Ocho Rios and Port Antonio are provided by a local airline, Jamaica Air Ser- vices. There are four other small public airports which accommodate general aviation and over 30 private landing strips owned by the mining and sugar companies. All public airports are operated by the Civil Aviation Department of the Ministry of Public Utilities, Communicationsand Transport. Revenues from landing fees, rentals, concessionsand licenses, but excluding travel tax, rose from J$ 660,000 in 1962/63 to an estimated J$ 1.8 million in 1972/73. Operating expenditureshave increased during the same period from some J$ 460,000 to J$ 1.7 million.

2.10 The sharp increase in tourism in recent years has had a major impact on Jamaica's internationalair traffic. Passenger movements at the two major airports increased between 1965 and 1970 at an average rate of 14% p.a., to over 500,000 at each. Freight movements and general aviation traffic have also increased considerably. The sharp traffic increase has led to congestion in aircraft ground cperations and traffic handling at both major airports. Based on the recommendationsof Canadian consultants (Kates, Peat Marwick and Company and Montreal Engineering)financed by CIDA, the Governmenthas requested Bank financing for an airport developmentproject to improve facilitiesat both Montego Bay and Kingston Airports. An appraisal mission has been scheduled for May 1973.

(v) Ports

2.11 Jamaica has 13 active ports, all privately owned and operated. Two of them, Kingston and Montego Bay, are primarily general cargo ports, handling most of the country's imports,while the other 11 are specialized and handle mainly exports. Kingston handles over 80% of the island's im- ports (4.0 million metric tons in 1970) and about 7% of its exports (13.0 million metric tons in 1970). Among the other ports, there are five effi- ciently handling the mining companies'export needs; the largest is Port Rhoades on the northwest coast, which deals with 5 million tons of bauxite annually. The other six are used to export agriculturalproducts such as sugar, molasses and bananas, and some agriculturalproducts are also handled through the mining companies'ports.

(vi) Pipelines

2.12 Pipelines owned and operated by the private sector carry fuel from the ESSO refinery in Kingston to various major consumers, to the railway loading station and from some ports to the bauxite mines and alumina plants. Specific informationon the extent of the pipeline network is not available.

C. Transport Policy and Coordination

2.13 Transport policy is the responsibilityof several Government departmentsand agencies. The Ministry of Public Utilities,Communications and Transport is responsiblefor overall policy formulationfor aviation, ports and railways,while the Ministry of Works (MOW) is in charge of for- mulating policies for public roads. Parish roads are under the jurisdiction of Parish Councils, which, at the national level, are the responsibilityof the Ministry of Local Government. The Ministry of Industry and Tourism deals with policy formulation on shipping matters. Overall economic planning was transferredin 1972 from the Ministry of Finance to a new National Planning Agency to allow the planning process to operate more effectively than previ- ously. One of the main tasks of the Agency, under the guidance of the Ministerial-levelNational Economic Council (NEC), is the planning of invest- ments, including investment in transport.

2.14 In general, the users of roads, ports and airports meet the capital and operating costs, includingoverheads, of these services,while railway users pay only part of the costs of the services they receive. Taxation on individualusers varies even within modes. For example, diesel-enginedve- hicles are favored with a low level of taxation since there are no taxes on diesel fuel, while vehicles with gasoline engines pay a high excise duty on gasoline. Governmentpolicy on taxation of transport users has not been de- fined in terms of specific goals, and available informationdoes not provide a basis on which to judge the adequacy of existing taxation policies in relation to the efficient use of the transportsystem. -6 -

2.15 Little competition presently exists among modes. Each mode is highly specialized,and diversion from one to another has occurred only on a small scale, largely limited to diversion from railway to road. No seri- ous competition among modes is foreseen.

3. THE ROAD SYSTEM AND ROAD TRANSPORT

A. The Road Network and its Traffic

3.01 The road network of Jamaica is, for the size of the island, relatively extensive, totaling nearly 10,000 miles, of which over 8,000 miles are suitable for vehicular traffic (Table 1). The network was de- veloped from horse-drawn carriage and bridle roads by gradual improvement and adaptation to motor vehicle traffic; it is not surprising, therefore, that the geometrical standards of the roads are, by modern criteria, poor, but, nevertheless, generally appropriate in the context of Jamaica. Most of the asphaltic pavements were constructedbetween 1950 and 1960 but, be- cause of deferment of periodic resurfacing,widespread aging anidfatigue are evident in the surface of paved roads, although there are few potholes or pavement base failures. High intensity rainfall results in frequent flood damage.

3.02 Vehicle license registrationin Jamaica increased from 23,262 units in 1955 to 102,000 in 1969, representingan annual growth rate of about 11%. No reliable information on annual vehicle licenses is available for the last few years. Cars account for about 75% of the total vehicle fleet. The vehicle density, 50 vehicles per 1,000 persons, is the fifth highest among Latin American and Caribbean countries, following Trinidad and Tobago, Uruguay, Argentina and Venezuela.

3.03 Traffic counts were carried out by MOW at about 50 points on the main road network between 1964 and 1972. From these, it appears that the highest traffic volumes on the island are on the Kingston-SpanishTown road (ADT 13,000) and the Spanish Town-Mandevilleroad (ADT 6,000). Other main roads near Kingston, Spanish Town, Montego Bay and Ocho Rios have relatively heavy traffic with ADT's from 3,000 to 6,000. Most of the remaining arterial roads have ADT's between 500 and 2,000 while, for most of the secondary main roads, ADT is between 50 and 250. Because of the island's relativelysmall size (para. 2.01), average trip lengths are short. Seasonal fluctuationsof traffic on the main roads are no more than 10%.

3.04 The MOW traffic counts indicate that traffic volumes grew at an average rate of 8.5% for the whole island during 1964-1972,with growth rates on specific roads varying between 4% p.a. and 13% p.a. Traffic growth has been particularlyhigh on roads associated with bauxite (over 12% p.a.) and with tourism (over 10% p.a.). The correspondingfigure for roads serv- ing agriculturalareas - mainly Parish roads - is no more than about 4% p.a. These rates are generally consistentwith the growth of traffic expressed in vehicle-miles,estimated by LVI (para. 1.02) at 9.5% p.a. from 1962 to 1970, and with the growth of gasoline consumption (11.8% p.a. between 1964 and 1970).

3.05 Speeds on the network are limited by alignmentsand average only about 30 mph for cars and 25 mph for trucks. From a study of (a) a report by the Road Research Laboratory (UK) in 1962, (b) the report on the Jamaica TransportationSurvey in 1970 (para. 1.02) and (c) TPOS' work in 1972 (para. 1.04), it is evident that speeds have not increasedsignificantly in the past 10 years. Vehicle operating costs are generally high and reflect the poor surface quality and low geometricalstandards. The proposed project aims mainly at strengthening the pavement and improving the riding quality, although minor improvementsof the alignment and other features are included (para. 4.05). Major improvementof geometric standards for certain roads with high traffic volume will be carried out within the new construction program being prepared by the Government (para. 3.15).

3.06 Prices charged by the road transport industry have not been studied in detail, but there is evidence that freight rates are relatively high. For example, between Kingston and Spanish Town (15 miles), the rate for a five-ton load is normally quoted at the equivalent of US4 40/ton-mile; between Kingston and Montego Bay, the longest typical haul on the island (120 miles), the rate for a 30-ton load is equivalen;tto US4 21/ton-mile. However, rates are not maintained unduly high because of insufficientcapac- ity or difficulty in acquiring vehicles. It is conmmonfor smaller truckers to have the purchase of their trucks financed by commercial companies for whom they carry freight. The rate at which the truck fleet has been growing in the past few years suggests that there are no restrictionson the expan- sion of the fleet to meet demand.

3.07 Permissiblevehicle weights are governed by the Road Traffic Law and are set out in detail in the Road Traffic Regulations, 1938, as amended through 1971. The essentialsof the Regulations,insofar as they apply to trucks and other heavy vehicles, are given in Annex 1 to this report. In summary, for trucks, including articulated trucks, permissible total weights, but not permissibleaxle weights, are specified;a maximum axle weight is, however, specified for public passengervehicles. Vehicle weights in excess of those specified in the Regulationsmay, however, be authorizedby the Minister (responsiblefor transport). The "penalty" for operating trucks in excess of vehicle weights normally permitted by the Regulations is E1.00 per annum for each 1,000 pounds authorized in excess of the limit permitted by the Regulations.

3,08 These Regulations are deficient in that they:

(a) specify gross weights rather than axle weights; and

(b) greatly undercharge owners of vehicles, heavier than those normally permitted by the Regulations,for the effect of overloadingon the pavements. - 8 -

The problem,is one which does not permit of rapid or easy solution, since the licensing system is well entrenched. However, as a move in the desir- able direction, the Bank, during negotiations,obtained an assurance from Government that, within three years of the date of the Loan Agreement,orsuch other period as shall be agreed between the Government and the Bank, it will: (a) revise the Regulations to appropriatelydefine permissible vehicle weights and axle loadings for all vehicles and (b) review the road user charges in relation to vehicles which are licensed to exceed normally permissible limits in order to see if the charges can reflect more adequately the effect of op- erations of such vehicles on the road network.

B. Administration: The Ministry of Works

3.09 The planning, constructionand maintenance of arterial and secon- dary main roads (Table 1) are the responsibilityof MOW. The tecutnicalwork of MOW is organized under the Chief Technical Director on a funct4onal basis (Chart 1); thus the Ministry's responsibilityfor roads is shared among five directorates. The Directorate of Technical Services (DTS) is responsible for survey, design, estimates, specifications,procurement of contract work above US$11,000 which is financed from budgetary sources, land acquisition,traffic surveys, laboratory investigationsand research; it has an establishmentof 172, including 27 civil engineers. The Directorate of Electrical and Mechanical Services (DEMS) is responsible for electrical installationsin Government build- ings and for all vehicles and equipment of MOW; it has an establishmentof 742, including six mechanical engineers. Specifically,DEMS allocates and controls the funds for the operation, maintenance and repairs of all plants and vehicles allocated to the directorates of MOW. The Directorate of Maintenance (DM) is responsible for maintaining roads, bridges, buildings and drainage channels; it has a staff of 1,484, including 359 technical staff, but no professional engineers. The Directorate of Construction (DC) is responsible for execution and administrationof all capital projects carried out by MOW and financed from the national budget; it has an establishmentof 79, including four civil engineers. The Directorate of Major Projects (DMP) administers and controls externally financed projects. It has an establishmentof 10, including five civil engineers.

3.10 The organizationalstructure of the MOW was overhaulledsome nine years ago and is generally satisfactory. Although a separate entity respon- sible only for roads would be more efficient from the narrow viewpoint of the administrationof the road system, there would be no justificationfor such a restructuringof MOW at this time. No difficultiesarise from grouping of maintenance of roads and buildings within one directorate,since separate personnel are assigned to each work, and budgetary allocations and equipment are also separated. The relatively small scale of operations would, in any case, probably preclude a rational case being made for such a separation of functions.

C. Road Planning and Financing

3.11 The road planning responsibilityof MOW is exercised mainly by the Chief Technical Director assisted by DMP. However, the Government has normally relied on consultantsto prepare major highway investments,first - 9 -

the UK Road Research Laboratory in 1962 and later LVI (para. 1.02). LVI recommendedestablishment of a Directorateof Planning,which would be re- sponsible for (a) economic evaluationof all transportationprojects and for maintainingan adequate data base for planning and (b) developmentand imple- mentation of a national transportpolicy, but this recommendationhas not yet been fully implementedby Government. However, the Government is presently recruiting staff to strengthen its highway planning unit in MOW. Additionally, within the recently establishedNational Planning Agency (para. 2.13), there is a unit responsiblefor infrastructureplanning, including transportation. Meanwhile, DMP is carrying out the planning function insofar as it relates to road projects to be externally financed. During negotiations, the Govern- ment assured the Bank that basic traffic and technical data will be collected on a continuing basis and that studies will be carried out as and when neces- sary for transport planning and policy formulation.

3.12 Annual estimates are submitted by MOW in November for the fiscal year commencing the following April. Authorized budgetary allocations are, however, sometimes received by MOW only in the following September. This slow budgetary process results in an inefficientprogramming of work, since directoratesnaturally tend to hold back during the first half of the fiscal year as an insurance against over-expenditureof allocations.

3.13 Road expendituresover the period 1965-1973have been financed mostly (94%) with local funds through budgetary appropriations;external financing (6%) has been provided by IBRD (para. 1.01), CIDA and USAID. The Bank's participation,although small compared with total road expenditure, represented about two-thirdsof external financing during the period.

3.14 Total expenditureon roads rose from US$10.3 million in 1965/66 to US$21.1 million in 1970/71, and to an estimated US$32.1 million in 1972/73 (Table 2). Expenditure on constructionalmost tripled over the period 1965- 1971, increasing from US$5.6 million to US$14.0 million; in the same period, maintenance expendituresincreased from US$3.5 million to US$5.4 million. Currently,maintenance expendituresare about US$8.3 million per year. This substantialincrease derives primarily from two factors: a US$1.4 million special labor-employmentmaintenance program, a result of Government employ- ment policy; and general cost and salary increases. Revenues from road users, although not specificallyearmarked for road financing, have been consist- ently higher than total road expenditures (Table 3).

3.15 Jamaica's current road investment plans are mainly based on the work of LVI (para. 1.02). The firm's ongoing work (in effect, the second stage of the CIDA-financedstudies) is likely to recommend constructionof about 120 miles of arterial roads and 200 miles of secondary and parochial roads over 10 years. Government has provisionallyplanned for half of this program to be implementedduring the period 1973-1977 at a cost of about US$29 million for the arterial roads program, and US$14 million for the secondary roads program, with external financing from IBRD and IDB. The Government contributionswould amount to about US$22 million or about USS4.3 million p.a. over the five-year period, on the basis of 50% of foreign financing. - 10 -

3.16 In addition to the above proposed program, Government, supported by a USAID loan of US$10.0 million, has already embarked on a US$16.8 mil- lion rural feeder road program for the constructionof about 300 miles of such roads over the period 1970-1977. This program has been economically justified on the basis of increases in production from higher yields and extension of the cultivated areas, stimulated by improved access to markets.

D. Engineeringand Construction

3.17 DTS is responsible for all aspects of engineering (survey, site and laboratory investigationand design) of capital projects financed wholly from the budget. The standard and quality of the work appear adequate. DMP is responsible for similar services for projects financed externally and operates through the use of consultants.

3.18 Constructionis carried out both by force account and by contract. DC, for example, carries out some work such as earthmoving and road base constructionby force account, but paving works in general are executed by contract. Internationalcompetitive bidding is used for externally-financed work; work financed internallyis awarded to Jamaican firms either by com- petitive bidding or by negotiated contract (para. 3.19). The local capacity for road work comprises three firms specializingin asphaltic concrete pre- mix and about 20 firms capable of undertakingsmall scale civil works.

3.19 MOW has a practice of fragmenting road constructionand improvement work into small lots; because of this practice, bidding becomes uneconomical and, as a result, contracts below US$11,000 are procured by negotiation. This has encouraged the development of a local small scale contracting in- dustry, but it has had an adverse influence on unit rates, which are much higher than in many other countries. LVI reported, for instance, that rates for typical road constructionoperations in Jamaica are 150-300% higher than those obtaining in eastern Canada, the reasons being mainly fragmentationof work, low total volume of work and low utilization of generally out-of-date equipment. The large road program proposed for the next five years may re- sult in a wider interest by both internationaland domestic contractors, leading to increased competition and a lowering of rates. E. Maintenance

3.20 The structure of the DM is shown on Chart 2. The structure at Area level is sound, but there is a noticeable imbalance in the span of control between Areas and Headquarters. Specifically,nine officers report to the Director of Maintenance who, additionally,is required to deal with a considerablenumber of claims, complaints and requests from the public in connectionwith the road network; thus, he has little time left for his pri- mary duties of planning and supervisionof road maintenance. To help correct this imbalance,TPOS (para. 1.04) recommended the creation of an additional (professional)level, the County, in the structure of the Directorate. - 11 -

3.21 The establishmentof DM is sizable and is about 50% of all MOW personnel;however, there is no professionalengineer in the Directorate (para. 3.09). At Headquarters,there are only eight staff in total, in- cluding clerical staff, which is insufficientto ensure planning,programming, costing and control of maintenancework. TPOS recommendedthe appointment in Headquartersof a senior administrativeofficer to deal with complaints and administrativematters on behalf of the Director,and an increase in clerical staff. The consultantsalso recommendedthat a senior professional member of the staff of DTS be given responsibilityfor forecastingand meeting technicalrequirements of DM.

3.22 The establishmentof DM at Area and Parish levels is adequate. Each Area Senior Superintendentis responsiblefor two Parishes. His office is located at one of his Parish offices, and this Parish - because of his presence - is the responsibilityof an assistant superintendentonly; the other Parish in the area is the responsibility of a superintendent. TPOS recommended that assistant superintendents be upgraded when eligible, and be given full responsibilityfor their Parishes, thus relieving the Senior Superintendentsfrom this duty for more effectivesupervision of maintenance in their Areas.

3.23 Each Parish has an allocationof basic maintenanceequipment and vehicles. Most of the equipment is old and about 50% of the vehicles are over five years old; hence, repairs (which are carried out in the four DENS work- shops situated at Kingston, Richmond,Montego Bay and Mandeville)are fre- quent. The supply of spare parts is adequate, and time spent for individual repairs is not excessive. Nevertheless, because of the age of the equipment, availabilityis low, about 75% on average. To supplement available equipment, there is a considerablerecourse to hiring; about 35% of haulage is done by hired trucks, and graders, traxcavatorsand bitumen distributorsare hired for about 80% of the work. Utilization,both of departmentaland hired equip- ment, is low, due to fragmentationand dispersion of work.

3.24 Maintenancework is carried out both by force account and by contract. Current practice is to contract nearly all asphalt resurfacing work and about 50% of resealing. Routine maintenance activities,such as grass cutting and drain cleaning,are generallyperformed on a piece- work basis in the form of "petty task" contractslimited to a maximum value of US$22 awarded to individuals. Area or Parish Superintendentscan award contractsup to a maximum of US$11,000; the usual practice is to award con- tracts up to this figure by negotiationwith contractorslocated in the Parish concerned.

3.25 Maintenanceis programmed on a day-to-day basis to deal with the most urgent repairs (particularlypatching of potholes and of damaged edges of pavement),most urgent resealing,and repairs of flood damage and of pavement failures. This leads to a scattering and fragmentationof work which, in turn, results in low efficiency of labor and equipment and in high cost of work. Moreover, due to delay in approval of annual budgets, there is a considerablevariation in workload over the fiscal year; LVI reported, for instance, that employment of temporarylabor in one Parish in 1968 varied - 12 -

from 200 in April to 2,210 in December. The fragmentationof work, non- competitive procurement and non-uniform workload result in a very high cost of road maintenance, reaching about US$3,000 per mile per year, 1/ overheads and cost of equipment included. TPOS recommended that the availabilityof equipment be increased by introducingpreventive maintenance routines at Parish level and that a road maintenance program be prepared for each Parish for planning and control of maintenance work.

3.26 The preparation of programs and budgetary estimates for road maintenance is the responsibility,in the first instance, of the Senior Superintendentsof the Areas. Allocations,when finally approved, however, tend to be appreciably less than the Areas' estimates because of reductions made during the review process in MOW and the Ministry of Finance. Intro- duction of rational planning and control of maintenance work would help reduce the cost of maintenance and would lead to more realistic budgeting and allocations.

3.27 Specificallyas regards periodic maintenance of the paved roads (that is, asphaltic overlay), the current budgetary allocation is sufficient only for about 25% of the annual requirement of 200 miles of overlay. This has been the situation over recent years, and the backlog currently is so great that TPOS recommended an urgent program of resurfacing and resealing of about 1,500 miles of public roads; the consultants'economic analysis led them to conclude that 50% of the work should be completed within one year and 75% within the first two years, although, clearly, financial and physical constraints would preclude such a concentratedprogram. The consultantsalso recommended a technical assistance program of about 300 man-months to help implement the work and to train DM personnel in better planning and control.

4. THE PROJECT

A. Project Description

4.01 The objectives of the project are to improve certain major roads in Jamaica; to reduce the backlog of maintenance on others; and generally to improve the structure, staffing and procedures of the Ministry of Works, insofar as they relate to maintenance of the country's road system. In de- tail, the project comprises:

(a) Improvementof about 440 miles of paved main roads, generally by provision of an asphaltic overlay;

(b) Maintenance of a further 250 miles or thereaboutsby provision of asphaltic resealing;

1/ About half this figure would be considered adequate in many countries. - 13 -

(c) Certain minor works in conjunctionwith (a) and (b);

(d) Provision of road maintenanceequipment and a small quantity of workshop equipmentand tools;

(e) Restructuringof the DM and improvementin the staff- ing and proceduresof the MOW, insofar as they relate to road maintenance;

(f) Provisionof technicalassistance to aid in"the imple- mentation of (a) through (e) preceding.

The project would be spread over about five years to ensure (a) an acceptable load on budgetary resources and (b) a broadly uniform load on the local contractingindustry, which is expected to participatein a great portion of the civil works.

B. Road Improvementand Maintenance

4.02 The proposed project provides for resurfacingwith asphaltic overlay, generally about 1-1/2 inches thick, of some 380 miles of arterial roads (representingabout 80% of the island's total mileage of arterial roads) and of some 60 miles of secondarymain roads (Table 4 and Map). The road sections, selected on the basis of TPOS' work, are characterizedby pavements which, although generallysound, are beginning to show signs of surface distress and are becoming increasinglysusceptible to excessive wear by the relativelyheavy traffic to which they are subjected. The asphaltic overlays proposed would help restore the riding quality of, and significantlystrengthen, the pavementsand would help maintain the integrity of the existing pavement structures.

4.03 An overlay of 1-1/2 inch thicknesson average (and probably within the range of 1 inch to 2 inches) has been assumed for estimatingcost. The specific thickness for each section would be determinedmore precisely by a rational design based on the present strength of the pavement, determined by deflectionmeasurements, and the expected axle weight profile. To deter- mine this profile, a survey would be made by MOW, assisted by the consultants, to ascertain the axle load distributionof current traffic; this distribution would then be projected over a 10-year period (the life used in the economic evaluation),assuming a certain growth and compositionof traffic.

4.04 The project also provides for resealingwith a double asphaltic surface treatment of a further 250 miles of secondarymain roads on which the pavements,while showing no obvious signs of structuraldistress, are becoming dry and are losing their waterproofproperties. The proposed asphaltic surface treatmentwould reseal the pavement surfaces against the ingress of moisture and thus help conserve the pavement strength. While it would be possible to indicate in general terms which sections may be in need of resealing in the light of current conditions,bearing in mind that the work would be spread over about five years and that deterioration,for many reasons, may not proceed as currentlyenvisaged, the roads to be resealed - 14 - have not been formally listed in the project description; they should, how- ever, be agreed with Government from time to time during the execution of the project, in the light of road and traffic conditions then prevailing. The procedures by which the Government and the Bank would agree on the road sections to be included for resealing were discussed and agreed during nego- tiations.

4.05 The project additionallyprovides for limited minor works to be carried out in conjunctionwith this resurfacing and resealing work, with the aim of improving the worst of the geometrical features of the roads and the roadside drainage. The geometrical improvement envisaged comprises easing the sharpest bends and restoring the profile of the pavement where it is seriously out of shape.

C. Provision of Road Maintenance and Workshop Equipment

4.06 The unsatisfactorycondition of the basic equipment in the Parishes has been described earlier (para. 3.23). With the aim of improving the cap- ability of the 13 Parishes for routine maintenance operations, the project includes provision of essential equipment such as trucks, personnel carriers, graders, and loaders. This provision is equivalent to about US$200,000 a Parish, and is based on the recommendationsof the TPOS study; details of the equipment are given in Table 5. The provision for workshop equipment and tools for the four DEMS workshops (para. 3.23) is also in line with TPOS proposals for introducing preventive maintenance for Parish maintenance equipment.

D. Restructuring of DM; Improvementof Staffing and Procedures

4.07 The present structure, staffing and procedures of DM (paras. 3.20- 3.25) militate against the Directorate'sefficient working. The project therefore includes appropriatemeasures to initiate action for improvement in all three aspects.

4.08 Regarding the structure of DM, TPOS recommended that the six Area offices be replaced by three "county" offices. However, while accepting the proposal to introduce three "county" offices, the Government considers that the Area offices should be retained. Since the Area offices are currently well organized and the Senior Superintendentscarry out their work satis- factorily, there is a persuasive case for their retention. Nevertheless, the "county level" should be introduced by the creation of three new "county engineer" posts to be staffed by professionalengineers (Chart 2). The effect of this change in the structure of the DM would be twofold: it would provide an opportunity to introduce professionalengineers into line manage- ment and it would reduce the span of control of the Director, which is at present excessivelywide. An assurance was obtained from the Government dur- ing negotiationsthat three "county engineer" posts would be introduced as a professionallevel with duties and responsibilitiesto be determined in agreementwith the Bank and to be reviewedfrom time to time in the light of changing circumstances. - 15 -

4.09 As regards personnel,the project envisages appointment to DM, and their retention,of four professionalcivil engineers,a senior administrative officer and an accountant. An assurance to this effect was obtained from Governmentduring negotiations. Three of the four civil engineerswould begin to act as "county engineers" (para. 4.08) and the fourth as technical assistant to the Director; the accountantwould be responsiblefor the costing of all maintenance work and the senior administrativeofficer would be responsible for much of the administrativeand public relations load currently borne by the Director. This additional staff, and indeed all staff of DM, would be trained by the technical assistanceto be provided under the project (para. 4.14); from this point of view, the additional staff would be consideredas counterpartsto the experts supplied under the technicalassistance.

4.10 The conditions of service and career prospects for the additional staff should be such as to attract and retain personnel of appropriatecaliber. Since appointmentof this additional staff would be crucial to the implementa- tion of the project, specificallyto improvementof the DM, it would be made a condition of effectivenessof the loan.

4.11 Improvementof maintenance proceduresunder the project may be considered in the context of the Area/Parish level and the national level. At the Area/Parish level, the improvementmost urgently required is the introductionof costing of work; a knowledge of the total cost (including, for instance, the running cost and depreciationof equipment)would provide an essential part of the feedback to Area/Parishmanagement for proper plan- ning of work and control of labor and equipment. Costing of maintenance work would in no way be a substitute for, or conflict with, Government's normal accounting procedures; these latter would continue in DM as in all other branches and agencies of Government, but they do not enable the true cost of maintenancework to be determinedsince it is accounted for in more than one directorate of the Ministry (para. 3.09). Costing should be gradually introduced,possibly on a pilot basis initially,using the additional staff to be appointed to DM (para. 4.09), aided by the experts to be provided under the technical assistance. An assurance that Governmentwould introduce costing of road maintenance operations within a time limit to be agreed with the Bank was obtained during negotiations.

4.12 Also at the local level, the practice of negotiated contracts (paras. 3.19 and 3.24). other than petty contracts below about J$ 500, should, in gen- eral, gradually be eliminated. With the introductionof costing and better planning, it should be possible to plan the work to be placed with local con- tractors so that it would be large enough to be attractive for competitive bidding. An assurance was obtained from Governmentat negotiationsthat the practice of negotiated contracts,apart from petty contracts or in exceptional circumstances,would be phased out within two years of the date of the Loan Agreement, or such other time as the Government and the Bank may agree upon.

4.13 At the national level, there is need for a comprehensivemaintenance plan; such a plan, covering a five-year period, was proposed by TPOS but was incompatiblein some respects with the physical and financial constraintsof the country. A revision of the TPOS plan should logically take into account - 16 -

the true cost of maintenanceoperations; thus, its formulationshould be deferred until some experienceof costing is available. Moreover, the for- mulation of such a five-yearplan would benefit from the technicalassistance to be provided under the project. However, this assistance would be occupied to a large extent during the early part of the project period with the estab- lishment of planning and costing procedures,procurement and supervisionof the civil works. A period of about six months should be sufficient for this preliminarywork; an assurancewas obtained from the Government that a com- prehensive five-yearnational road maintenanceplan would be prepared in physical and monetary terms within one year of the date of the Loan Agreement or such further period as the Government and the Bank may determine. Meanwhile, annual budgetary allocations for road maintenance should be maintained in real terms at the present level, pending implementationof the five-yearmaintenance plan; an assurance to this effect was obtained during negotiations.

E. Technical Assistance

4.14 The project includes provision for about 220 man-months of tech- nical assistancewhich, although less than the 300 man-months proposed by TPOS, is considered sufficient for this project; the disciplinesand periods for which this assistancewould be provided are given in Table 6. The tech- nical assistance team would help in:

(a) planning and execution of minor works to be carried out in conjunctionwith the road improvementand maintenance;

(b) preparationof procurementdocuments for equipment and civil works, and in evaluation of bids;

(c) developmentof costing and work planning procedures including the work necessary in DEMS for equipment maintenance and costing;

(d) introductionof the "county" concept in the structure of DM;

(e) supervisionof the civil works under the project;

(f) developmentof a five-year national road maintenance plan; and

(g) training of the DM personnel.

The counterpartsfor the members of the team would primarily be the additional staff to be appointed to DM (para. 4.09). Participationin the foregoing work by the technical assistance team should automaticallyprovide training for the counterpartsand others of the staff of DM and DEMS. The Government has already initiated negotiations with the consultants TPOS for a contract to undertake the technical assistance assignment. Since this technical assistance would be essential for the successful implementationof the project, signature of the contract on terms and conditions satisfactoryto the Bank would be a conditionof effectivenessof the loan. - 17 -

4.15 Training of the DM personnel in the improved proceduresof road maintenancewill be one of the main duties of the consultantsengaged for technicalassistance. The objectivesof this program will be to train the new professionalstaff and the superintendentsin costing, budgeting,plan- ning, organization,procurement and supervisionof road maintenanceand to train the technical personnelin Area and Parish units in elementarycosting of works, in efficientorganization and executionof works, and in supervision and administrationof work by contract. Training will be carried out by the in-servicemethod and by short courses. It will take place mainly during the first three years of the project, during which period the greater part of the consultants'input would be made. It is estimatedthat at least 25% of the experts' time or a total of about 50 to 60 man-monthswould be used for training purposes.

F. Cost Estimates

4.16 Cost estimates for the project are given in detail in Table 7 and are summarized below:

/1 Includingallowance for restorationof profile. 7/2 Mainly ditches, bends,etc. - 18 -

4.17 The cost estimates for asphaltic overlay and for asphaltic resealing have been based on the TPOS estimates which the consultants prepared,using current contract rates in Jamaica; preparatorywork has been estimated at about US$2,750 per mile. The cost of equipment has been based on the c.i.f. cost Kingston of the equipment listed in Table 5. The cost of technical assistance has been based on TPOS' estimates. The bases for the contingency allowances are given in Table 7.

4.18 The foreign exchange component of asphaltic overlay has been as- sessed at about 52%, on the assumption that the work would be undertaken by foreign contractors. However, the subdivision of the work (para. 4.22) may result in some of it being undertaken by local firms, in which case a small amount of local financing would result. The foreign exchange component of asphaltic resealing has been assessed at 42% on the assumption that this work would be undertaken by Jamaican contractors. The foreign exchange component of technical assistance has been assessed at 81% on the basis of the recent experience in the TPOS study.

G. Financing and Disbursement

4.19 The proposed Bank loan would finance the foreign exchange component of the project, estimated at US$9.3 million equivalent, except to the extent mentioned in paragraph 4.18, should some of the work be undertaken by local firms. Local costs would be met from budgetary allocations. On the assumption that the technical assistance team would be operational before signing of the Loan Agreement, retroactive financing for this item, from April 16, 1973, estimated at no more than US$120,000,would be required from the proposed loan.

4.20 The disbursementfrom the loan account would be made on the follow- ing basis:

(a) for asphaltic overlay, 52% of the contractor'sbills;

(b) for asphaltic resealing, 42% of the contractor'sbills;

(c) for purchase of equipment, 100% of the c.i.f. cost Kingston;

(d) for technical assistance, 100% of the foreign exchange cost.

The projected disbursements through the project period are indicated in Table 8. Surplus funds remaining in the loan account on completion of the project would be cancelled, unless needed for concurrentwork related to the project and/or feasibility studies approved by the Bank for further investments.

H. Execution

4.21 Implementationof the project would be the responsibilityof the Ministry of Works acting through the Chief Technical Director. The technical assistance team would assist in all aspects (para. 4.14). - 19 _

4.22 The asphalticoverlay would be carried out by contract following internationalbidding in accordancewith the Bank's Guidelinesfor Procurement; the work would be bid in two tranchesof about US$3 million each, and sepa- rated by a period of two years, to spread the load on the budgetaryfunds and to ensure effectivesupervision. The details and schedule of procurementwere agreed with the Bank. Each tranchewould consistof a number of lots, and bidders would be allowed, consistentwith their capacity,to bid for any com- bination of lots. An assurancewas obtained from Governmentduring negotiations that:

(a) prior to bidding the overlaywork, the strength of pavements to be overlaid would be determined,and an axle load survey of present trafficwould be made (para. 4.03) so that the overlay could be designed rationally. The technicalas- sistance team would help in the design of the overlay and preparationof the bidding documents,and in supervision of the work;

(b) the contractsfor the overlay would include restorationof the profile of pavementswhere these have become dangerously deformed.

4.23 The asphaltic resealingwould be scatteredover the secondarymain roads throughoutthe island and spread over about a five-yearperiod. The nature of the work makes it unlikely that it would be attractive to firms not already establishedin Jamaica; procurementwould generallybe in accord- ance with the Bank's Guidelines,except that the work would be advertisedonly in Jamaica. The detailsand schedule of procurementwere agreed with the Bank during negotiations.

4.24 Prior to commencementof the asphalticoverlay and resealing, the worst of the geometricfeatures (dangeroushorizontal bends, sharp vertical curves, etc.) of the roads involvedwould be removed by DM (para. 4.05). An assurance to this effect was obtained at negotiationsand the procedure to be followed by the Governmentand the Bank for defining such work agreed upon. A further assurancewas obtained from the Government that, for all lengths of road to be overlaid or resealed,roadside drainage,where deficient,would be improved during the period of the project by provision of (a) adequate sur- facing to, and drainage of, shoulders;and (b) longitudinalditches of ade- quate section and depth to drain the pavement structure.

4.25 Procurementof equipmentwould be through internationalcompetitive bidding, in accordancewith the Bank's Guidelines;the procedure and schedule for procurementwas agreed by the Bank. Bidding documentswould stipulate that successfulbidders would arrange for an adequate supply of spare parts through local commercialrepresentatives. The bulk of the equipmentwould be procured during the first half of the project, leaving about 25% for a second procurement,probably in the third year. This phasingwould prevent a large arrival of equipmentat one time and would provide flexibilityregarding the type of equipment that may be required in the light of experience gained dur- ing the first two years of the project. - 20 -

4.26 Technical assistance to help in all aspects of the project would be procured by the Government under terms and conditionsacceptable to the Bank. The counterpart personnel would basically be the additional staff to be provided in DM (para. 4.09). Signature of the technical assistance contract as a condition of loan effectiveness (para. 4.14) would ensure that this essential element would be available from the inception of the project.

5. ECONOMIC EVALUATION

A. General

5.01 The proposed project would improve both the physical condition of the road network and the organizationdirectly responsible for maintaining it (DM). Physically, it would benefit all classes of road from the local Parish to the arterial road; from an organizationviewpoint, it would affect all levels of DM, from the Parish superintendentsand the road gangs they control to the Director.

5.02 The physical impact of the project would be evident in three ways: from the provision of equipment for day-to-daymaintenance; from the reseal- ing of about 250 miles of roads; and from the resurfacing of a further 440 miles, these latter including most of the island's arterial road system. As regards DM, the project would have an impact on administrativeprocedures, particularly those relating to costing; on the structure of the organization; and on its staffing. Determination of the true costs of maintenance opera- tions would provide all levels with a management tool not currently available; it should lead to more effective maintenance and, hence, either to a reduc- tion in the current cost of maintenance or, more desirably, to a greater main- tenance effort for the same expenditure.

5.03 The equipment to be provided would chiefly affect 2,000 miles of secondary main roads which are scattered through all 13 Parishes of Jamaica. Adequate maintenance of such roads - an essential link in the farm-to-market system - is required for the development of internal production or,where such development has already taken place, to ensure that it would not slow down because of a deterioration in the road system.

B. Asphaltic Overlay

5.04 The effect of the overlay would be two-fold in that it would, at the same time, make the roads stronger and improve riding conditions. The road sections selected (Table 4) are among the heaviest traffickedin the country; counts have been taken both by MOW and consultantsover the past 10 years (paras. 3.03 and 3.04), and from these and other sources, ADT and traffic growth rates have been derived for the economic evaluation.

5.05 Specifically,traffic counts were taken over a period of five or seven days by TPOS in late 1972, and the figures were checked with those derived from LVI's single-daycounts in June 1972. After adjusting for - 21 -

seasonal variations, it appears that ADT on the arterial roads considered in the project varies between 3,400 and 500 and that on the secondarymain roads from 1,300 to 500. Details of current traffic compositionare given in Table 9.

5.06 From the counts over the last 10 years, it appears that traffic growth has varied by type of route (bauxite or agricultural),and even with- in the same type route, depending on the volume of traffic and the area served. The economic evaluationhas included estimatesof future normal traffic on the roads to be overlayedby consideringannual growth rates and compositionof traffic over a 10-year period (the assumed economic life of the project works). For this 10-yearperiod, growth has been considered in two five-yearstages; the figures adopted (Table 9) are 5.0-9.0% for cars, 5.0-8.7% for light trucks, 4.5-8.5% for medium trucks, 3.0-8.5% fosrheavy trucks and 3.2-6.0% for buses. The sum of the products of these growth rates and the traffic on each road section matched the overall traffic growth rates deduced by TPOS. These projectionsof growth are aieceptable considering that improvementof the network would possibly result in a higher annual vehicle mileage than the present one. No induced traffic has been considered in the economic evaluation on the assumption that transport de- mand on the project's roads is relatively inelastic to changes in vehicle operating costs.

5.07 Quantifiablebenefits arising from the asphaltic overlay and con- sidered in the economic evaluation are:

(a) reduction in vehicle operating costs due to improved riding surfaces; and

(b) prevention of increasedvehicle operating costs that would occur if the roads were allowed to deteriorate further.

Quantificationof vehicle operating costs has been based on the concept of "Road Class" devised by TPOS. This is essentiallya furictionof surface roughness; definitionsof the various Road Classes and of the operating cost in each Area are indicatedin Table 10. The evalvuationof benefits arising from improved riding surfaces is based on the assumption that all roads to be improved by asphaltic overlay will be raised to Class 1.25. Typical operating savings from this improvementare as;follows: - 22 -

Savings in J cents/veh mile assuming pavements raised to Class 1.25 (Table 11)

Large Truck 3.3 (11%) 6.8 (19%) 8.9 (24%)

Note: Figures in brackets indicate reduction on existing operating costs.

5.08 Quantificationof benefits resulting from the avoidance of deter- ioratioinof pavements has been based on the (conservative)assumption that existing operating costs would be maintained for the five years commencing 1973 and would thereafterincrease at a rate of about 5% per annum for the next four years, then 10% per annum for the next three years (to about 1985, that is, to the end of the 10-year economic life assumed following the end of construction in 1975).

5.09 Overall, about 60% of total benefits are attributable to preven- tion of increased operating costs and 40% to reduction in costs consequent upon better riding conditions.

5.10 The economic cost used in the evaluation includes the cost of asphaltic overlay and an allowance for the necessary restoration of profile which would be required prior to such work (Table 4). The economic cost for unskilled labor has been taken as 50% of actual wages because of the high rate of unemploymentin Jamaica (para. 2.03), although even without this "shadow pricing" of the cost of labor, the work is amply justified.

5.11 The estimated net benefits discounted over a 10-year economic life give a most likely value for the economic return greater than 50%; the first year benefits on average are higher than 30% of this part of the project cost. A sensitivity test applied to measure the response of economic return to lower initial traffic, lower traffic growth, no increase in vehicle operating cost on existing roads, higher constructioncosts and operating costs higher than assumed on the improved roads indicates that, even with these variations, the overall economic return, 27% (Table 12), and the first year benefit ratio (14%), remain acceptable.

5.12 The economic return calculation has taken into account the likely employment effects of the project (para. 5.10). On the basis of data supplied by local contractors,the additional employment generated by the improvement program would provide up to about 1,000 additional jobs over the project period. This figure does not, of course, represent the whole employment impact, since there would be secondary effects arising from expenditures made by beneficiariesof incomes generated by the project. - 23 -

C. Asphaltic Resealing

5.13 The proposed asphaltic resealingwould help preserve pavements which, although currently sound, are in danger of becoming porous and vul- nerable to damage from entry of surface water if no action is taken to re- seal them. Investmentin resealing now would thus produce benefits from deferment of investmentin reconstructingsuch pavements. This element of the project has been evaluatedby comparing the cost of resealing now with the present worth of reconstructingthe road if it were allowed to fail. Specifically,if the resealing cost (about US$12,000 per mile) were less than the present cost of reconstructionin a future year, the proposed invest- ment in resealing now would be justified (Table 13).

5.14 It is not possible to determine exactly, for each road section, when failure would take place without resealing. For evaluatingpurposes it was first assumed that failure would occur four years hence and that reconstructionthen, including rehabilitationof the base course and asphaltic overlay, would cost about US$30,000 per mile. Since reconstruction then would imply an economic life longer than the 10-year period used in the project analysis, a present worth of the salvage value of the reconstructed road in year 10 has been estimated to arrive at the net cost of reconstruction in year 4. The analysis indicates that it would be economicallyadvantageous to reseal now, rather than to do nothing now and reconstructin four years' time; the economic return for resealing now is about 19%. If road failure were assumed to take place not in four years' time, but in two years' and six years' time, the economic returns on resealing now would be 25% and 14% respectively;obviously, the sooner failure would take place, the more jus- tifiable the proposed resealing. The possibilityof failure beyond six years from now was not consideredbecause it would imply that the pavement is currently in good condition. These economic returns can be considered conservativein that they do not take into account the increase in vehicle operating costs in the "without case" as the road pavemLentprogressively breaks up.

D. Road Maintenance and Workshop Equipment

5.15 The benefits from the provision of road maintenance and workshop equipment have been assessed by considering the annual benefits that would be required to produce an economic return of 10% on the cost of such equip- ment (US$2.4 million). Assuming an average life for the equipment of seven years, the annual benefits required would be about US$500,000, or about US$250 per mile per year. If, on the roads to which the investment would relate, there was an ADT of about 200 (equivalent to about 73,000 vehicles per mile per year), this would imply benefits in the form of savings in vehicle operating costs of USJ 0.3 per vehicle mile (Jamaican e 0.3 per vehL-- cle mile, approximately). These savings represent only a few percent of cur- rent vehicle operating costs (Table 10), and it is obvicusly reasonable to assume that such a modest improvement in operating costs can be made as a result of the improved maintenance from the new equipment. The investment in the new equipment is therefore justified. - _24-

6. AGREEMENTS REACHEDAND RECOITMENDATION

6.01 During loan negotiations, thle Government agreed to the followinhi-

(a) revision, within three years of the date of the Loan Agreement. or such other period as shall be agreed between the Government and -lie Bank. of the Road Traffic Regulations (1) to appropriateLy iefine permissible vehicle w:eights and axle la. 'n ;s for all vehic.le4 and (2) to review thie road user charges in relation to vehicles which are licensed to exceed normally permissible limits in order to see if the charges can reflect more ade- quately the effect of operations of such vehicles on the road network (para. 3.08):

(b) collection on a continuing basis of basic traffic and technical data, including the conduct of studies, as and when necessary, for transport planning and policy formulation (para. 3.11);

(c) appointment and retention within the Directoratc of Maintenance of three qualified engineers as "county engineers', one pro- fessional civil engineer, a senior administrative officer and an accountant, with duties and responsibilities to be agreed with the Bank and to be reviewed from1time to time in the light of changing circumstances (paras. 4.08, 4.09 and 4.10);

(d) introduction of costing of road maintenance operations within a time limit to be agreed with the Bank (para. 4.11);

(e) phasing out of the practice of negotiated contracts, apart from petty contracts or in exceptional circumstances, within two years of the date of the Loan Agreement or such other time as the Government and the Bank may agree upon (para. 4.12);

(f) preparation of a comprehensive five-year nationali road main- tenance plan expressed in monetary and physical terms wJithin one year of the date of the Loan Agreement or sticu1 further period as the Government and the Bank may determioe (para. 4.13);

(g) provision of annual budgetary allocations for road maintenance at the present level, in real terms, pending implementation of the five-year maintenance plan (para. 4.13)

(h) preparatory work necessary for the design of tho asphaltic overlay and the restoration of pavement profile (para. 4.22);

(i) elimination of thieworst of the geometric features of the roads to be improved prior to commencement of the road improve- ment work (para. 4.24);

(j) improvement of roadside drainage on the roads to be improved (para. 4.24). - 25 -

6.02 Conditions for loan effectivenesswill be (a) the appointmentof the professionalstaff mentioned in paragraph 6.01 (c) preceding and (b) the signature of a contract with a firm of consultantsacceptable to, and on ,terms and conditions agreed by, the Bank for the technical assistance.

6.03 The project provides a suitable basis for a loan of US$9.3 million equivalent. On the basis of the average useful life of asphaltic overlay and resealing and the length of the project duration, the appropriateterm for the loan would be 15 years, including a five-yearperiod of grace.

'ay For thepurposes7 of this project the vehicle operating costs do not include the incremental operating cost of curves and grades since the proposed investment does not change alignments. Average vehicle operating costs may well be up to 20, higher on each class of road respectively when due allowance is made for curves and grades. iNote: For road classes classified between 1.00 and 2.00 and between 2.00 and 3.00, vehicle operating costs have been interpolated.

1/ First class roads (1no) are paved wivh a surface irregularity, measured by the burp integrator, of less than 25 inches per mile. Average speed on level tangent roads around 40 mph. The lane width would generally be at leas-t 12 feet with 6 feet shoulders on either side. 2/ Second class roads (2.00) are paved roads in poor condition with a surface irregularity o-f' 115 Inches per mile. TLypical speed is around 32 nph. The lane -width is at least 9 Seet but there may be no shoulders on the road. 3/ Third class roads (3.00) are gravel roads anu badly failed paved roads with a surface irregularity of at least 200 inches per mile and have not been engineered. Typical speed is around 15 mph.
