Copyright © African Development Bank 2014 Department of Transport and ICT, OITC Prepared by : Richard MALINGA Transport Engineer, OITC2 Sector Manager (OIC) : Mamady SOUARE Sector Director : Amadou OUMAROU STUDY ON QUALITY OF BANK FINANCED ROAD PROJECTS FOREWORD The African Development Bank has over the years supported the Regional Member Countries in their efforts in improving accessibility and livelihoods of people, through the execution of road transport projects. We can proudly talk of the many kilometres of road improvements through maintenance interventions, rehabilitation, new construction or upgrading that we have supported across the continent. The focus has in many instances been paved (bitumi- nous) roads, but we have also supported the improvement of unpaved roads. The Bank reflected on the outputs in the road sub-sector, taking cognisance of the fact that we have promoted and supported the improvement of over 10,000 km of road in the conti- nent since 2006, with 4,000 km of these since 2010. We considered it prudent that we take stock of what we have been doing, to establish that we have not been doing the wrong thing to the detriment of the Bank’s overarching mission of sustainable development; and what do we need to do to avoid doing the wrong thing. Are the roads we are supporting to build of the right quality? Are these roads sustainable? These are some of the questions that we asked ourselves, and we believe these are questions that many road users would also ask us. The Bank has a well-defined project cycle, one stage of which is the post-evaluation of projects following completion. This is undertaken by the Independent Evaluation Department (IDEV), which would typically consider the development impact and effec- tiveness of the projects in relation to the defined outcomes as well as the strategic issues. Other internal organs also progressively look at the fiduciary aspects as relate to the execution of the projects. Our intention at this stage was to focus on the technical aspects of the projects delivery and hence the formulation of the Study. The Study looked at technical parameters to provide answers to the question of whe- ther the standards and specifications adopted in Bank financed projects are of inter- national best practice, and further more if these are indeed adhered to. The Study was therefore akin to a technical audit of Bank financed road projects, based on the sam- pling of recently completed projects in eight selected countries across the continent. Whereas we have obtained a sense of satisfaction in the findings from the Study, we are quick to point out that we need to keenly pursue the matter of ensuring quality and sustainability. We are glad to note that some stakeholders promptly responded to the early findings from the Study and undertook further investigations to address the issues pointed out. Collective responsibility is required at all levels by each of the stakeholders to ensure that our contribu- tion to addressing the accessibility issue in Africa through good quality well maintained roads is sustained. This is what the continent should continue to strive for. We owe it to the people – across the age, gender and geographical, in the spirit of the Bank’s Inclusive Growth. Amadou Oumarou DIRECTOR, TRANSPORT, URBAN DEVELOPMENT & ICT DEPARTMENT 2 THE AFRICAN DEVELOPMENT BANK TABLE OF CONTENTS African Development Bank Group ACKNOWLEDGEMENTS The Study was undertaken on behalf of the Bank by M/s Intercontinental Consul- tants and Technocrats Pvt. Ltd of India. The Bank is grateful for their input and efforts in ensuring the completion of the Study and overcoming the various chal- lenges in conducting the Study. The Study was initiated by Mr Gilbert Mbesherubusa (retired Vice President, In- frastructure, Private Sector & Regional Integration) when he was Director of the Transport and ICT Department. He was always keen on the progress of the Study in reflection of his vast contribution to the Bank’s transport sector work in his time at the Bank. The Report was prepared under the overall leadership of Mr. Amadou Oumarou, Director of the Transport and ICT Department, and the two Division Managers in the Department, Mr. Jean Kizito Kabanguka and Dr. Abayomi Babalola. The Study was coordinated Mr. Richard Malinga (Transport Engineer) who was Task Mana- ger for the Study. The Study received the support of the staff members of the Transport and ICT Department of the Bank, at the various review as well as from other departments, notably the Results and Quality Assurance Department (ORQR), specifically the Quality Assurance Division. The Study would not have been possible without the cooperation of the Govern- ments and Road Authorities/ Agencies in the Study Countries of Benin, Cameroon, Democratic Republic of Congo, Ghana, Kenya, Tanzania, Tunisia and Uganda. The various authorities provided valuable information for the Study. The full sup- port of the Bank’s staff in the field offices in some of the Study Countries - Came- roon, Democratic Republic of Congo, Ghana, Kenya, Tanzania and Uganda is also recognised. These provided assistance in the coordination of the in-country activities and have continued to follow up with the various agencies to ensure that specific findings from the Study are followed up. The Bank’s Senior Management is also acknowledged for the keen interest in the Study and providing the resources that enabled the Study to be undertaken. 3 STUDY ON QUALITY OF BANK FINANCED ROAD PROJECTS TABLE OF CONTENTS Abbreviations A-1 To A-2 Executive Summary Es-1 To Es-10 1.0 Introduction 1.1 Background 1-1 1.2 Objectives of the Assignment 1-2 1.3 Organization of the Report 1-2 2.0 The assignment 2.1 Scope of the Assignment 2-1 2.2 Organization and Management of the of the Project 2-2 2.3 Approach to Assignment 2-3 2.4 Assignment Outputs 2-9 2.5 Challenges Faced in the Conduct of the Assignment 2-10 3.0 The study roads 3.1 Introduction 3-1 3.2 Benin 3-1 3.3 Cameroon 3-4 3.4 Democratic Republic of Congo (DRC) 3-7 3.5 Ghana 3-8 3.6 Kenya 3-14 3.7 Tanzania 3-18 3.8 Tunisia 3-22 3.9 Uganda 3-26 3.10 Assessment of Selected Roads Against Bank’s Criteria 3-28 4.0 Assessment of the quality of selected roads 4.1 Introduction 4-1 4.1.1 General 4-1 4.1.2 Assessment of Quality through Visual Survey 4-1 4.1.3 Assessment of Quality in Terms of Riding Quality 4-3 4.1.4 Assessment of Quality of Construction in Terms of Structural Capability 4-4 4.1.5 Assessment of Quality in Terms of Pavement Layer Characteristics 4-6 4.2 Assessment of Roads in Benin 4-7 4.2.1 Assessment of Quality through Visual Survey 4-7 4.2.2 Assessment of Quality in Terms of Riding Quality 4-8 4.2.3 Assessment of Quality of Construction in Terms of Structural Capability 4-8 4 TABLE OF CONTENTS African Development Bank Group 4.2.4 Assessment of Quality in Terms of Pavement Layer Characteristics 4-9 4.2.5 Summary 4-10 4.3 Assessment of Roads in Cameroon 4-11 4.3.1 Assessment of Quality through Visual Survey 4-11 4.3.2 Assessment of Quality in Terms of Riding Quality 4-14 4.3.3 Assessment of Quality of Construction in Terms of Structural Capability 4-14 4.3.4 Assessment of Quality in Terms of Pavement Layer Characteristics 4-17 4.3.5 Summary 4-17 4.4 Assessment of Roads in Democratic Republic of Congo (DRC) 4-17 4.4.1 Assessment of Quality through Visual Survey 4-17 4.4.2 Assessment of Quality of Construction in Terms of Structural Capability 4-21 4.4.3 Assessment of Quality in Terms of Pavement Layer Characteristics 4-21 4.4.4 Summary 4-21 4.5 Assessment of Roads in Ghana 4-22 4.5.1 Assessment of Quality through Visual Survey 4-22 4.5.2 Assessment of Quality in Terms of Riding Quality 4-27 4.5.3 Assessment of Quality of Construction in Terms of Structural Capability 4-29 4.5.4 Assessment of Quality in Terms of Pavement Layer Characteristics 4-30 4.5.5 Summary 4-31 4.6 Assessment of Roads in Kenya 4-31 4.6.1 Assessment of Quality through Visual Survey 4-31 4.6.2 Assessment of Quality in Terms of Riding Quality 4-34 4.6.3 Assessment of Quality of Construction in Terms of Structural Capability 4-36 4.6.4 Assessment of Quality in Terms of Pavement Layer Characteristics 4-36 4.6.5 Summary 4-36 4.7 Assessment of Roads in Tanzania - Zanzibar 4-37 4.7.1 Assessment of Quality through Visual Survey 4-37 4.7.2 Assessment of Quality in Terms of Riding Quality 4-40 4.7.3 Assessment of Quality of Construction in Terms of Structural Capability 4-40 4.7.4 Assessment of Quality in Terms of Pavement Layer Characteristics 4-41 4.7.5 Summary 4-41 4.8 Assessment of Roads in Tanzania - Mainland 4-41 4.8.1 Assessment of Quality through Visual Survey 4-41 4.8.2 Assessment of Quality in Terms of Riding Quality 4-47 4.8.3 Assessment of Quality of Construction in Terms of Structural Capability 4-7 5 STUDY ON QUALITY OF BANK FINANCED ROAD PROJECTS 4.8.4 Assessment of Quality in Terms of Pavement Layer Characteristics 4-49 4.8.5 Summary 4-49 4.9 Assessment of Roads in Tunisia 4-49 4.9.1 Assessment of Quality through Visual Survey 4-49 4.9.2
