The EAG was also apprised regarding the revised rates as per the Govt. Resolution dated 03/12/2011 for availing the consultancy service of national consultants.

5 Minutes of Agenda No. 4a & 4b:

Geophysical survey along the revised corridor by NIOT, Chennai (1/4) including geotechnical investigation and Geotechnical Survey & investigation for dam design

1.0 Dr. Jena, Deputy Project Director of NIOT presented a detailed progress of important items, reasons for variations of items and delay of this study. He also stated that single beam echo sounding (SBES), single beam bathymetry and grab sampling quantities were increased in quantities. Whereas Multi-Beam Echo Sounding, single channel seismic profiling SCSP, side scan sonar imaging and Marine magnetometer survey quantities were decreased. He further stated that field survey was completed in all respects except submission of report. 2.0 SAC submitted a detailed report of this study. Prof. Tad Murty, Chairman, highlighted the following important issues. 1) Cdr. K L Rao, Hydrographer (Retd) and National consultant verified all data collection and processing. Dr. N. Ghosh, National Consultant, has also verified data analysis of Single channel seismic profiling SCSP and analysis of Marine magnetometer. Dr. N. Ghosh, Shri Pancholi and Shri Kasliwal, National consultants have verified the results of Cone Pentrometer (CPT), Vibrocorer Investigations and the entire geophysical investigation chart/ DTM. 2) The geotechnical data has been obtained to a maximum depth of 6 m. The geophysical and geotechnical map of Blocks A, B,C,D have been prepared by the NIOT. 3) The magnetic map along the dam corridor was useful in ruling out the presence of any hazard on the seafloor like wreckage of ship or magnetic bodies. The survey indicates

6 intrusive bodies in the basement rock, lineaments/ faults. The interpretation also indicates depth variation of basement rock below the thick alluvial deposits. The seismic survey indicates the presence of west bounding marginal fault of cambay Graben. Different lineaments are found to be in general agreement with geological regional map of the area. 4) A Digital Elevation Model (DEM) is being generated by compiling all sounding data collected from various teams. The DEM may be used to generate maps in hardcopy in any scale and contours at any interval. 5) Dr. K. M. Sivakholundu, Mr. D. Venkat Rao, Mr. Badrinarayan of NIOT along with Dr. N. Ghosh, Mr. D. M. Pancholi and Mr. V. K. Kasliwal, National consultants and other SAC members studies in depth “Geophysical survey along the revised dam corridor” considering (1) Seismic Magnitude Map of Gujarat, (2) Sub bottom profiling, (3) Corridor Bathymetry Contour with SBP Coverage, (4) Sequential overlay of Bathymetry Contours, (5) Magnetic anomaly map along dam corridor, (6) Single beam bathymetry @ Shallow Portions of Dam Corridor, (7) Seabed Sonic image from Multi-beam backscatter for Area- A, B, C & D, (8) Grab Sampling, (9) Particle size distribution Curve, and (10) Results of Electro-vibro core tests and cone penetration tests are used for fixing dam alignments. 6) NIOT has first investigated 21 alternative (L-1 to L-22 excluding L-17) lines for the water Channel A, B, C and D. The observed fault lines/lineaments for all the deep water channel areas with various geophysical and geotechnical data, NIOT recommended three alignments ( L-3, L-11 and

7 L-19) for further investigation. SAC agreed for these selections. 7) These three alignments have thereafter been further scrutinized by SAC members and NIOT officials and they have recommended Alignment L-3 from geophysical, geological & geomorphological considerations. Dam alignment L3 have the advantages of intercepting the additional flows of rivers (Kalubhar, Ghelo and Rangholi) in the reservoir, comparatively easier to join the approaches on both the sides as well as avoiding ship breaking units, Nirma factory and Kabadi (scrap) market. 8) SAC members and NIOT have scrutinized the Geotechnical estimate/plan from above field data. Dr S. R. Gandhi, IIT, Chennai was also consulted for this investigation.SAC agreed for number of bore holes, location and depth. The unit rates of drilling looks on quite lower side looking to imported Jack up platform, their availability and site adverse conditions and therefore SAC suggested to take help for preparing estimate of international firm M/S Fugro Geotech Pvt. Ltd. or any other. 3.0 EAG, after detailed deliberations on above points, considered all observations of SAC. EAG suggested that NIOT should submit the revised estimate and draft final report to the department for approval. EAG found L3 alignment as the most appropriate alignment in respect of carrying out detailed Geotechnical Investigation and Approach Road Planning. EAG also agreed with the Geotechnical Estimate, location and depth of bore holes for further Geotechnical Investigations prepared by National Consultants and vetted by NIOT and SAC.

8 Minutes of Agenda No. 5

Bathymetric Survey in the (Northern Portion) by NIOT, Chennai (2/4)

1.0 Dr. Jena of NIOT presented the details of progress of important activities as well as the reasons for delays. He stated that Dr. P.N. Shridhar (NRSA) explained SAC the status of ongoing work carried out on satellite imageries by NRSA. He had planned to complete this work by March 2013. 2.0 Prof. Tad Murty, Chairman SAC, submitted detailed report and also highlighted important issues as under: 1. NIOT has provided the Sontec single point Current meter along with Pressure Tide Gauge (PTG) in place of catamaran type observatories due to technical problems. This will not materially affect quality of data. Now NIOT has installed the systems at 2 m depth instead of 10 m. The data from these 14 installations may be adequate to cover the data requirement for modeling. Further year 2013 monsoon data will also be available for modeling. 2. Non- availability of monsoon data does not pose much of a problem for modeling studies as due to high tidal range, the tidal currents will not be affected due to fresh water discharges during monsoon. 3. NIOT will provide all input data in DTM format which can be used by other institutes for their studies purposes. No input from hydrodynamic modeling is required. 3.0 EAG, after deliberations, accepted the observations/ clarifications of SAC and also suggested that NIOT should submit the proposal for time limit extension as well as revised estimate to department for their approval.

9 Minutes of Agenda No. 6

Bathymetric Survey in the Gulf of Khambhat (Southern Portion) by NIOT, Chennai (3/4) 1.0 Dr. Jena of NIOT presented the details of progress of various items including reasons, any variations in items and delay. He stated that earlier Bathymetric work was estimated 18000 lkm from the Google earth image. Now on actual survey it is increased to 21400 lkm. The cost will also increase from Rs. 548.8 Lakhs to Rs. 648.76 Lakhs. This work will be completed by December-2012. 2.0 SAC carried out scientific auditing of this study at Chennai and prepared detailed report. Dr. Tad Murty, Chairman, SAC highlighted following important points: 2.1 NIOT will provide Bathymetry survey in scale of 1:15000 with interval of 0.5 m (Softcopy). They will also give data in DTM/ASCII format which can be used for any mathematical model as input data. 2.2 These data in ASCII/DTM will be provided by NIOT to other studies like storm surge, tsunami, sea level rise, port etc. They can then incorporated directly into their studies. Hence, there is no need of any integration software of various studies. 2.3 All institutes should submit a copy of operational software along with guidelines of usage to the Kalpasar Department in acceptable magnetic media. 3.0 EAG, after detailed deliberations, accepted all observations/clarifications of SAC and also suggested to NIOT to submit the revised time limit extension proposal including revised estimate to department for their approval.

10 Minutes of Agenda No. 7

Progress of hydrodynamic and sediment model studies and related measurements for Gulf of Khambhat by National Institute of Ocean Technology (NIOT), Chennai (4/4)

1.0 Dr. Jena. B. K., Deputy Project Director, NIOT made the presentation with the detailed bar chart for completion all activities. 2.0 Prof. Tad Murty, Chairman SAC also appraised the EAG as follows: 2.1 MOA has been signed recently on 28th, May, 2012 by NIOT. Bathymetric and met-ocean observations results are expected to be available by December 2012 which essentially forms input for this study. Preparatory works like DTM preparation, coastline digitization and preliminary model setup using DELFT3D have been commenced. 2.2 NIOT likely to enter into a MOU with DELTARES Netherland for model technical support. The open source code of Delta3D to be made available by DELTARES is one of the worlds’ state of art for hydrodynamic models. DELTARES is one of the worlds’ leading institutes with proven track record in both research and consultancy in the field of coastal and river engineering. The SAC is confident for the capability of software developed by DELTARES. 2.3 SAC is of the opinion the software used by NIOT need not be integrated with other studies. But the results of all models will be integrated to estimate the forces and freeboard for the structure.

11 3.0 EAG, after deliberations, considered and accepted observations of SAC for this study. EAG suggested that the NIOT should use the internationally and universally accepted software so that, in future, when any PPP agency comes forward for carrying out project, Software can easily be integrated. NIOT should prepare a detailed Road map alongwith the role/ responsible/ working day etc of various team experts and furnish such road map of this study to the department.

Minutes of Agenda No. 8

Presentation of Salient features of Impact of storm surges, Wind waves and Seiches on the proposed Kalpasar dam

Prof. S. K. Dube, IITD made the presentation on Storm Surge and Seiche while Prof. P. K. Bhaskaran from IIT Kharagpur made the presentation on Wind Wave Component. They have incorporated all the observations raised by department on their presentations. Prof. Tad Murty, Chairman SAC, also appraised the EAG. Following important points are discussed:

1.0 Storm Surges I. The resolution was determined through sensitivity analysis of the grid. The study region covers the entire coastal regions of Gujarat and North Maharashtra. II. Tide and surge interaction is always non-linear; hence the model employed non-linear interaction. Model has been tested and validated for value of ∆P=66 hpa i.e. highest recorded central pressure drop of all historical cyclones that have hit Gujarat coast. III. The intensity of tropical cyclones might increase in the range of 2-11% due to climate change. Twenty (20) sets

12 of each experiment at the width of 10 km intervals were carried out for following three scenarios (with and without dam) leading to a total of 120 experiments.(a) No climate change,(b) Intensification of tropical cyclone by 7% (average value) and (c) Intensification by 11%

(extreme case). IV. Results give between 4 and 9 m along the various regions of the Gulf and 6 to 8 m near the dam PMSS elevations including tide. In the case of no dam, the storm surge enters straight into the very shallow region of the head of the Gulf generating higher surges than in

the case of presence of dam.

2.0 Seiche component

Prof. Dube had given justifications of using MIKE 21 Model and the boundary of the model and the data used. The maximum seiches were observed during the 1998 cyclone. If the cyclone of that type would pass over the gulf of Khambhat, then it will induce a current of 0.5m/s inside the closed basin. The seiche amplitude in the basin is ranging from 5 mm to 20 cm.

Due to the decrease in fetch of wind to induce seiching, the results show the amplitude of seiche decreases and the time period decreases inside the dam. The amplitude of seiche increases and the time period decreases outside the dam.

3.0 Wind Wave Component I. Prof. Bhaskaran stated that SWAN is a third generation state-of-art wave model to obtain realistic estimates of wave parameters in coastal areas from given wind, bottom and current conditions. It comprises of various processes including wave generation, non-linear

13 interaction, dissipation and wave breaking mechanisms. The sedimentation mechanism has a role in modifying the frictional characteristics of wave propagation. Hence, appropriate bottom characteristics and loss due to frictional dissipation mechanism have been taken into account. II. The ENVISAT satellite data for significant wave heights were used in model validation. The set of numerical experiments considering the effects of with/without dam under no climate change, 7% and 11% wind field intensification is used. The wave setup computations were performed along the length of the proposed dam. III. Model was run with varying elevation, currents and wind data were provided at an interval of every 5 minutes along the cyclone tracks. The high resolution of time interval is sufficient to study the non-linear effects of wave-current-tide interaction. The results are as under: scenarios Cyclone Tracks without dam Cyclone Tracks with dam Corridor-3 Track through Corridor-3 Track through the Gulf. the Gulf. Max significant wave height Max significant wave height wave height attained along wave height attained along attained in dam location attained in dam location centre of gulf. centre of gulf. No climate 10.06 m 7.2 m 9.88 m 6.5 m change

Intensification of 10.59 m 7.7 m 10.45 m 7.4 m tropical cyclone by 7% (average value) Intensification by 10.74 m 7.9 m 10.74 m 7.6 m 11% (extreme case).

4.0 EAG, after deliberations accepted the clarifications made by Prof. Dube and Prof. Bhaskaran on observations made by the department. EAG suggested that IITD should complete the

14 study using fresh bathymetric data from NIOT and submit the draft final report before June, 2013. EAG suggested to take help of International Expert Prof. Ioan Nistor as well as other members of SAC as suggested by Prof Tad Murty for Estimation of combined forces of the dam due to storm surge, seiches, tsunami, wind waves etc. Forces calculations should be presented in the next EAG meeting.

Minutes of Agenda No. 9

Presentation of Interim Report on “Study of the impact of Tsunami effect on the design of proposed Kalpasar dam” by National Geographical Research Institute (NGRI), Hyderabad

1.0 Dr. Kirti Srivastava of NGRI, Hyderabad discussed with SAC at Chennai and thereafter Dr. Krishna of NGRI, Hyderabad, made the presentation in the 9th EAG meeting on “Study of impact of Tsunami effects on the design of Kalpasar dam”. NGRI and Prof. Tad Murty, Chairman, SAC also clarified the observations raised by the department.

I. NGRI is using the Tsunami N2 Model in this study. As per EAG suggestions, model was run considering earthquake at Makran Region up to 9.3 magnitude at a 5 km focal depth keeping other controlling parameters same. The amplification of the wave heights is being studied. Vertical elevation along the centre line of tsunami propagation and amplification at the continental shelf has been computed. NGRI has observed that near the dam site (Luhara), the tsunami reaches 432.2 minutes after

15 the earthquake and the tsunami height there will be 0.3686 m only. The wave heights at the ONGC- Mumbai High are around 0.52 m to 0.8 m. The study also shows that with rupture between 300 to 400 km in length and even with 9.5 magnitude earthquake at Makran region, NGRI has not observed any significant change in the wave heights as the bathymetry does not allow much amplification.

II. NGRI clarified that in the Gulf of Khambhat region, it is difficult to generate a tsunamigenic earthquake at shallow depths. There are no active volcanoes in the region. There are only mud volcanoes. Any small magnitude earthquakes in this region are not of thrust type. III. Once the NIOT bathymetric data are available, the final models would be run and several scenarios would be prepared and a final project report would be submitted. Prof. Ioan Nistor, International Consultant, will work out the tsunami forces. There is no requirement for integration of tsunami study with the one given to the IIT Roorkee/ GERI for earthquake studies in the vicinity of dam. IV. NIOT, NIO, NGRI, IIT Delhi, etc will provide Kalpasar Department with manual on how to use the data and set up the mathematical model that was used by them. This manual shall contain sample calculations if necessary. A copy of operational open source free software that is used may also be provided.

16 2.0 EAG, after deliberations, accepted the results of Makran tsunami at Kalpasar dam site. EAG also suggested that NGRI should complete the study using fresh data of bathymetry from NIOT and submit the draft final report by June, 2013. For the estimation of combined forces of the dam due to storm surge, seiches, tsunami, wind waves and tides etc, new studies should be initiated with the help of International Expert Prof. Ioan Nistor immediately.

Minutes of Agenda No. 10

“Study on the effect of sea level changes and regional climate changes on design of Kalpasar dam” by National Institute of Oceanography, Goa.

1. Prof. Tad Murty, Chairman, SAC explained that as per the NIO, Goa’s draft final report on the “Effect of sea level changes and regional climate changes on design of Kalpasar dam”, an average of 4 mm/year sea level rise is acceptable. He stated that if anticipated life span of the dam is considered to be 250 yrs, then 1 m free board will be required for Sea Level Rise in the design of dam. SAC compared this value with the practice of coastal engineering consulting companies (BAIRD Associates) also. SAC recommended that the NIO, Goa report be adapted. Prof. Tad Murty suggested to take the services of IITM, Pune for a detailed climate change study as NIO, Goa report on this issue is very preliminary.

2. EAG accepted the report of NIO, Goa as far as sea level rise study is concerned and agreed with SAC to carry out climate change study with the help of IITM, Pune. Dr. Ghosh National Consultant and CE (K-2) & AS would immediately contact Dr. Krishnakumar of IITM to obtain necessary proposal.

17 Minutes of agenda No. 11

Proposal for ‘‘Establishment of a network of seismological observatories for monitoring the seismic activity around

Kalpasar Project”

(1) GERI (Gujarat Engineering Research Institute), Vadodara made the presentation on the proposal for ‘‘Establishment of a network of seismological observatories for monitoring the seismic activity around Kalpasar Project”. Shri Khan from GERI stated that IS:4967–1968: ‘Recommendations for seismic instrumentation for river valley projects’, close spaced local network of observatories for monitoring of micro-earthquake activity of the project area is necessary. The primary objective of seismological network is to investigate the sources of seismic activity in the vicinity of proposed site. Tentative locations of network of 8 Seismological observatories with latest Broad Band Digital Seismographs and Strong Motion Accelerographs (SMA) linked by VSAT based satellite system to the Central Seismic Data Centre at GERI is proposed. Shri Rao, Director, GERI explained that the present proposal for establishment of 8 Broad Band Seismological observatories + 4BBS stand by units and monitoring of the same for the period of five years is amounting Rs.700 lacs (Rs.460 lacs capital + Rs.237 lacs recurring cost for five years.) EAG has earlier suggested to first obtain vetting by ISR, Gujarat and IIT Roorkee.

(2) Seismic study activity of deployment, supervision, quality control of equipment’s including maintenance for design of dam, amounting to Rs 80.00 Lacs has been entrusted to IIT, Roorkee as approved in the 8th EAG meeting. As per Terms of

18 reference, IIT, Roorkee shall advise GERI from time to time as and when required on various work items such as deployment, supervision, interpretation, etc. IIT Roorkee has scrutinized and broadly agreed with the revised proposal of GERI for establishment of network of observatories with estimate amounting to Rs 769.78 lacs including technical work of Rs. 434.57 lacs and administrative work of Rs. 335.21 lacs.

(3) EAG, after detailed discussion, agreed with GERI’s proposal as recommended by IIT, Roorkee amounting to Rs. 769.78 lacs subject to compress the duration to one year (for establishment of the net work) with saving of about two-three months for establishment of observatories.

Minutes of Agenda No. 12 Selection of Alignment for construction of (1) Dr Yoginarsihman of M/s SECON Pvt. Ltd explained in details how three alternative alignments are selected. He explained that Alignment–1, Alignment-2 and Alignment-3 are 2.0 km, 3.65 km and 5.15 km d/s of village - Bhadbhut respectively. Various parameters such as River width available to accommodate barrage length, Afflux on water levels resulting from the barrage construction, area to be acquired for approach embankments, excavation for approach and tail channel, siltation problem, storage capacity, total cost of the project, vicinity of gas pipelines/ gas stations, villages and valuable properties, villages benefited by availability of fresh water and land area free from tide water and land reclaimed have been analysed for selecting the best alternative. Considering all these parameters, Alignment -3 i.e. 5.15 km d/s of village – Bhadbhut is recommended.

19 (2) All three alignments locations were shown to EAG members during their site visit on 15/07/2012. EAG members also found that on site the Alignment-3 is better than other two alternatives.

(3) The officials of Kalpasar department mentioned that planning of PCPIR of Dahej is in advance stage of approval. The draft development plan of PCPIR with various types of zones and road network are finalized by PCPIR. In case of Narmada Diversion Canal, Chief Secretary had advised Kalpasar department to follow the alignment as shown in the draft development plan to avoid the issues related to land acquisition in this region. Hence, to have better coordination with planning of PCPIR, it would be required to follow planning of road network finalized by PCPIR on right bank, as far as possible. Hence, alignment of right approach is required to be decided in consultation with PCPIR authority, which may need minor modification in alignment no.3 as proposed by M/s. SECON.

(4) The EAG considered the socio – economic and technical considerations of all the three alternatives and accepted the Alignment-3 as recommended by SECON and Group of National Level Consultants along with the department’s suggestion to kept the left bank approach straight (between and Utraj) instead a kink as proposed by SECON to avoid the reserved forest area and right bank approach of the barrage alignment with the final road alignment of PCPIR, which is in advance stage of approval by the concerned authority.

Determination of Various floods for the design of Bhadbhut barrage

Part-I Estimation of Design flood at Bhadbhut Barrage site

1.0 Dr. Yoganarasimhan of SECON Pvt. Ltd presented studies carried out for the estimation of design flood at barrage. He explained in detailed the methodology adopted for the working out flood computation

(i) The proposed barrage is located 150 km d/s of SSP. The Karjan river and the Orsang river are meeting the at 74 km & 108 km, respectively, in u/s of Bhadbhut Barrage. There are three major projects: Sardar Sarovar Project, Karjan Dam and Sukhi Dam in u/s of Bhadbhut Barrage. The free catchment below these three major projects is 8649 sq.km

(ii) The observed most severe storm of the year 1945 (2 days duration) at Kevadia colony is adopted as design storm. Average rainfall depths for the storm on seven sub basins are worked out and the 3 hourly percentage distributions for 48 hours storm have been applied to arrive rainfall distributions.

(iii) The design flood is worked out by superimposing: (i) The design flood at confluence of Karjan, Orsang,& Narmada rivers i.e. Karjan Confluence, (ii) Routing of combined floods at Karjan Confluence up to Bhadbhut Barrage site (iii) Sequential addition of flood between Karjan Confluence and barrage site.

21 (iv) The SSNNL Disaster Management Plan 2011(Flood Manual) provides the values of the flood of different return period at site. Accordingly, the values of flood at Bhadbhut site for various frequencies are worked out as under:

Flood frequency Discharge in cumecs (in year)

1:25 57750

1:50 66937

1:100 77505

1:500 86665

1:1000 98643 SPF (Entire Narmada basin) 105689

Above Flood Values are derived assuming no flood interception due to existing Indirasagar, Omkareshwar and Maheshwar Projects. Hence, potential and frequency of flood calculated as assessed for barrage on conservative side.

2.0 The EAG agreed with above flood frequency at Bhadbhut barrage site computed by M/S SECON Pvt. Ltd in consultation with Dr. Mathur & Shri Kaushik, National Consultant & vetted by the CDO, Gandhinagar. EAG also agreed to adopt the above flood for detailed design to be carried out by EPC agency (BOT).

22 Part II: Determination of design flood for Bhadbhut barrage

1.0 Dr. Yognarsimhan explained the various provision and standards used in for design of Barrage are as under:

(i) BIS 6966-1989, “Hydraulic Design of Barrage and Weirs- recommends 50 year frequency for design flood,

(ii) Central Board of Irrigation and Power’s Manual on barrage and weirs on permeable foundation, Volume I-1985 suggests to design the waterway to pass safely a flood of 1 in 50 or 1 in 100 years frequency,

(iii) Central Water Commission has recently finalized design flood of 1:50 year (22.07 lac cusec) for Garudehswar weir, which is located on Naramda River upstream of Bhadbhut Barrage.

(iv) Khosla Committee of Engineers recommends maximum recorded flood for a period greater than 50 years as design flood.

2.0 Generally civil engineering structures like dam, barrage, bridge, building, road, port etc. are designed on the basis of Indian Standards, wherever such IS is not available then only other guidelines are used. Hence M/S SECON has considered 1 in 100 years flood for design of Barrage, Gates and sub structure and also provided free board considering 1 in 500 year flood. Further M/S Secon, has also designed the barrage in such a way that it will pass flood of 105,689 cumecs (SPF), in which 1:100 year flood i.e. 77,505 cumecs will pass through barrage and balance 28,184 cumecs will be diverted to the flood plane on the left bank through the breaching section near barrage and thereafter under bridge portion of approach to the barrage.

23 3.0 Mr. Bryan Leyland, Member EAG, suggested to reexamine the provision of bridge as well as breaching section provided on left bank embankment. EAG accepted the suggestion of Mr. Bryan Leyland for reexamining the requirement of bridge & alternative of passing 28184 cumecs flood through barrage gates instead of breaching section. Kalpasar Department in consultation with M/S SECON should decide this issue at their level in consultation with Chairman, EAG.

4.0 EAG agreed to consider 1 in 100 year flood for design of Barrage structure.EAG also agreed to consider SPF flood passing through structure.EAG also suggested to use this flood for detailed barrage design to be carried out by EPC agency (BOT). EAG concurred to freeze the above mentioned design flood values so as to be used in various hydrological estimations for the Bhadbhut barrage project.

Minutes of Agenda No. 14

Design of barrage and appurtenant works for the proposed Bhadbhut barrage.

1.0 Dr. Yoganarasimhan and Shri Rama Iyenger of M/S SECON, Pvt. Ltd. Bangalore presented the design features of various components of barrage. They stated that as per the scope of work, the preliminary design and skematic drawings of the barrage have been prepared for the alignment No.3, 5.15 km downstream of Bhadbhut village. The PPP agency will prepare detailed design and drawings for construction purpose. Various components of barrage and bridge have been designed in accordance with the provision of IS:6966: 1989 “Hydraulic design of barrage and weirs Part-I alluvial reaches”, Manual on barrages and weirs on permeable foundation, (CBIP publication

24 No.179), IRC : 5-1998, IRC 78: 2000 & other relevant codes of BIS, IRC and manuals.

2.0 M/s. SECON Pvt. Ltd. has worked out the design features of main components of barrage, which are as under:

(i) Barrage

The net (effective) waterway as per Lacey’s theory works out to 1345m.The proposed total length is 1663 m including fish ladder and ship lock.

(ii) Gates

After detailed study of pros.& cons of vertical gates v/s radial gates, vertical gates have been proposed. 80 Nos. (Size 15.5m X 9.5m) for normal blocks, 10 Nos. (size 15.5m X 10.5m) for sluice blocks have been proposed. To prevent entry of sea water in to stilling basin, vertical gates (size 15.5m x 9.0m) have also proposed on d/s side.

(iii) Stilling basin & cutoffs

Total floor length is 79.85m,with thickness ranging from 3m to 4m.The u/s cut off of 17.5 depth (1R) and d/s & intermediate cut off of 28.5m depth (2R) are proposed.

(iv) Fish ladder

To provide passage for easy movement of fishes from sea to reservoir and vice versa, fish ladder of 5 m width with gate (size 5.0m X 10.50m) is provided in the barrage. Baffles with staggered gaps are proposed to reduce velocity up to 3m/sec for easy movement of fish.

25 (v) Navigation Lock

One gate of size 15.5m X 10.5m on both upstream and downstream side to build up water level is provided for movement of small boats from reservoir to sea side and vice– versa.

(vi) Bridge over Barrage

To create connectivity between Surat (Hazira)-Dahej via Olpad-Hansot, six lane bridges with M40 concrete grade of pre cast pre-stress concrete girder type super structure is provided. Overall length of bridge is 1663m.

(vii) Breaching Section & Bridge

The breaching section would consist of rock fill materials up to RL 8.5 m and earth material from RL 8.5 m to 12.0 m, in a length of 3000 m on left bank near barrage. This will permit passage of flood in excess of 1 in 100 year flood (up to SPF) by breaching at predetermined reservoir level.

To pass the flood coming through breaching section as well as local run off, bridge of 2110 m length having 85 spans each of 30 m width has been proposed.

(viii) Approach on both banks

Left approach of 6.65 km length & right approach of 4.70 km length are proposed. Six lane road is proposed on embankment.

EAG, after detailed discussion, broadly agreed for preliminary design and skematic drawings of the barrage and appurtenant structures, prepared by the consultancy firm. While agreeing for the provision of fish ladder and navigation lock (ship lock), suggested by M/S SECON,

26 the EAG suggested that the issue of double gates (u/s & d/s) as well as vertical gates verses radial gates and, breaching section cum bridge of approach should be reexamined by M/S SECON in consultation with C.D.O. Gandhinagar and submit their final proposal for EAG’s consideration.

Minutes of Agenda No.15

Design of flood protection embankment on both bank of Narmada river for Bhadbhut Barrage.

1.0 Mr. Rama Iyengar of M/s SECON, Bangalore explained that the left bank is relatively flat and the ground levels are varying from El 5.5 to 6 m. During the high flood, 400 sq.km. left bank area are coming under submergence. Hence flood protection against frequent flooding of low lying left bank area is necessary. Further due to the construction of barrage structure & embankment, water level would rise. M/S SECON proposed the flood embankment starting from the barrage up to Zadeswar Bridge near . M/s SECON has considered the flood protection embankments keeping a minimum width of water way of 1.6 km, so that minimum land comes under submergence. Mr Iyengar stated that as per IS 12094-Guide lines for planning & design of river embankment to protect agriculture land, 1 in 25 year flood frequency (57750 cumecs) can be considered. However, on conservative side the flood protection embankment is designed considering 1 in 100 year flood frequency (77505 cumecs) with 1.0 m free board.

2.0 M/S SECON earlier suggested the earthen embankment only. However, as per the suggestions of Kalpasar Department, they

27 have worked out alternative of RCC retaining wall also.Two alternatives of constructing the left bank embankments viz. RCC counter fort type retaining wall (either with stone columns or pile foundation) and earthen embankment were presented by M/S SECON.

a) On the left bank, RCC retaining wall and ground improvement is proposed with stone columns of 100 cm diameter to a depth of 6m, at 2m X 2m grid, if provided, the approximate cost will be Rs 5.2 lakh per meter. Total cost of RCC retaining wall worked out by M/S SECON is Rs 1250 crores. If ground improvement is carried out with pile foundation with 1.2m diameter bored piles driven up to a depth of 20m with 3.6m spacing both ways, then cost will rise to Rs 6.8 lakhs per meter. Hence, Total cost of RCC retaining wall will be about Rs.1634 crore. b) M/S SECON stated that, earthen/rock-fill embankment would be of simpler construction. Its average height would be 8 m with a top width of 5 m, side slopes of 2.5:1 with a free board of 1m. A 30m wide road at an average height of 3m above the local ground levels on the leeward side has been proposed. This would cost around Rs 70,000 per meter. Hence, total cost of Left Bank Embankment will be about Rs. 168 crore.

3.0 On the right bank, embankment would be of relatively smaller height because of the higher ground levels. The average height would be about 3m with a unit cost of Rs. 24,000 per metre and total cost of Right Bank Embankment will be Rs. 65 crore.

28 4.0 EAG discussed the design features of flood protection embankments in detail. EAG considered the cost of RCC protection wall which is 8 to 10 times costlier than Earthen/Rock fill embankment. Hence, finally recommended the alternative of earthen/ rock-fill embankment, in view of substantial reduction in cost, as compared to RCC construction. It was also suggested that 30 m wide road on the embankment should be on the top, instead of leeward side, so as to allow the river sideview for the travellers as this project can also be developed as river front project at later stage. This will further increase safety of embankment. The EAG also suggested to provide flood protection wall up to Railway bridge in phase I.

Minutes of Agenda No.16

Back water analysis of the proposed Bhadbhut barrage 1.0 Dr. Yoganarasimhan of M/S SECON Pvt. Ltd. in his presentation explained that

(i) On account of barrage and flood protection embankment, the natural river water course is restricted and consequently the water levels of barrage would rise. Hence back water analysis has been carried out to assess the afflux at four upstream bridges and to help in determining afflux flood levels at different locations and height of protection embankments. M/S SECON has used HEC-RAS model of Hydrologic Engineering Center software, (US Army Corps of Engineers), for one- dimensional back water analysis to compute the water surface profile for steady water flows.

29 (ii) The model was run (Bridge design requirement) for the discharge of 69,384 cumec (observed maximum so far and slightly more than 50 years flood). The following pre- barrage and post-barrage scenarios with, (i) Existing river condition without barrage (ii) Barrage with approach embankment on left, and (iii) Barrage + approach embankment + flood protection embankments were studied. The result shows that construction of barrage had negligible afflux of water levels at bridges. However, imposition of flood embankments with barrage raised the water levels more than the stipulated margin below the soffit levels of the bridges. (iii) M/S SECON has also carried out eight conditions to explore the possibility of lowering the afflux water levels effect at bridges by excavating higher ground levels in river bed such as Dhanturia Island and dredging of river bed and banks. Removal of Dhanturia island & river bed graded from Zadeshwer bridge/railway bridge to barrage will result in lowering the afflux level to acceptable limits. The quantum of dredging roughly works out to about 80 MM3 to 90MM3.The same material will be useful for construction of flood embankment. M/S SECON concluded that the afflux flood level at Bridges after construction of barrage and flood embankment with some dredging can be easily kept within the permissible limit.

2.0 EAG after detailed discussion agreed to accept to keep Left Bank flood embankment with 1.6 km River gorge width & dragging as suggested by M/S SECON but subject to the final dredging sections/quantity to be worked out during detailed design by BOT agency.

Traffic study and Toll Revenue Assessment of Bhadbhut Barrage (1) Mr. Manohar of M/s. SECON Pvt. Ltd. presented the traffic survey analysis for pre and post barrage scenario and explained that the road distance due to barrage will reduce by about 18 Km. between Dahej and Hansot. After barrage the Dahej- Hansot - Olpad - Surat new route would be developed. He explained that the various traffic surveys i.e. (1) 7 days continuous Classified Traffic Volume count at 5 Locations (2) Classified Turning Traffic Volume count at Intersections for duration of 12 Hours for two locations (3) Origin - Destination Surveys for period of 24 Hours for three locations (4) Willingness to pay toll surveys for period of 24 Hours at the same locations of O-D Survey, has been carried out by SECON in consultation with Shri R.K.Mehta, National Consultant to Kalpasar Department. He also explained the assumptions of Traffic generation due to upcoming PCPIR, Dahej and Traffic Growth rates for various categories of vehicle types in the influence area of barrage in the Gujarat State.

(2) Mr. Manohar explained that Assessment of Toll Rates was carried out as per NHAI guidelines and also with 25%, 50% and 75 % Savings in the Vehicle Operation Cost (VOC). Based on these Toll Rates, SECON, considering optimistic and most likely traffic growths scenarios, estimated Toll Revenue per year from year 2016 to 2039. SECON also suggested that traffic requires a minimum of 2-lane undivided carriage way in year 2016, 4 lane divided carriage way in the year 2018 and 6 lane carriage way in the year 2040-2041 based on the estimated traffic as per guidelines set in IRC-64-1990 in their

31 final Traffic Survey Report. As the project is to be executed under BOT model of PPP mode, SECON recommended to provide 6-lane divided carriage way in the tender document of the proposed Bhadbhut Barrage.

(3) EAG, after detailed discussion, accepted the Traffic Survey Report as submitted by M/s. SECON Pvt. Ltd. EAG further recommended to consider 6 - lane divided carriage way. EAG also accepted that as the project is proposed to be implemented on PPP mode, the toll rates shall be at the rate 25% of VOC for the initial five years and thereafter as per current NHAI policy (about 50% of VOC).

Minutes of Agenda No. 18

Industrial water demand for uses in Dahej PCPIR and other industries from Bhadbhut Barrage Project

(1) Mr. Shiva Prasad of M/s SECON Pvt. Ltd presented the details of domestic and industrial water demand survey and explained regarding water requirement of industries in GIDC estates and Dahej PCPIR region. He explained that due to non availability of permanent water source except Narmada river water, at present GIDC is pumping 58 MGD water from Narmada river at Angareshwar (70km upstream from Bhadbhut) to cater the needs of industries in GIDC estates and Dahej PCPIR region. But presently the Narmada river water up to Angareshwar is influenced by tidal ingress and is not usable/ fit even for industrial purposes.

32 (2) He further explained that Gujarat Industrial Development Corporation (GIDC) has planned for Petroleum, Chemical & Petrochemical Investment Region (PCPIR) in Dahej industrial area. GIDC has worked out industrial water requirement for PCPIR with different development scenario. He further stated that there is substantial water demand beyond year 2020. GIDC has worked out their projected demand for industrial use to the tune of 300 to 325 MGD (1370 to 1490 MLD) for uses of industries in GIDC estates and Dahej PCPIR region with identification of various sources.

(3) Shri A. B. Thakkar S.E., PIU-2, Vadodara further explained that the domestic water supply requirement from Bhadbhut barrage has been furnished by GWSSB to Kalpasar department. Accordingly the domestic water requirement works out to 60 MCM per year. Also it is planned to reactivate two defunct lift irrigation schemes having total command area of 1136 ha. Hence irrigation water requirement from Bhadbhut barrage is worked out as 10 MCM.

(4) Department of Industries and Mines has officially confirmed and conveyed the Bhadbhut barrage based water requirement of 200 MGD (910 MLD) for Dahej PCPIR region and 40 MGD (185 MLD) for GIDC Ankleshwar, Panoli and Jhagadia Estates, to Kalpasar Department on 13/07/2012. Hence, GIDC industrial water requirement, based on Bhadbhut barrage, will be 1095 MLD, say 1100 MLD, in year 2020 and onwards. Considering the element of uncertainty such as reduction in demand due to incremental rates, delay /abandonment in establishing industry, improved technology requiring less quantity of water etc., a conservative demand at 50% of 1100 MLD i.e. 550 MLD has been considered by Kalpasar Department for the revenue assessment.

33 Department has considered the present industrial water rate of Rs. 19.48 / m3 (for the year 2012-13) as per water rate policy in vogue in Water Resources Department with 10% annual increment till the rate reaches to Rs. 40/ m3 and thereafter at 5% to derive annual cash flow calculation (revenue generation).

(5) EAG agreed with the department’s proposal to consider industrial water demand of GIDC with 50% of total projected demand for revenue generation for calculation purpose and for using the same details for PPP tender paper. EAG also agreed for allocation of 60 MCM water for domestic water supply use and 10 MCM allocation for irrigation purposes.

Minutes of Agenda No. 19

2D Mathematical modeling for Bhadbhut Barrage

(1) Dr Yoginarsihman of M/s. SECON Pvt. Ltd. presented the study report on 2D Mathematical modeling for Bhadbhut Barrage using River 2D version 0.95a, January 2010 software in place of MIKE. He explained about the Program, its components, basic assumptions, requirement of input data for model, Finite Element Method with basic equations, parameters as Eddy viscosity coefficient, Courant Number etc.

(2) He explained that the modeling has been carried out for existing flow condition (Case-1) as well as for flow across barrage and bridge condition (Case-2). Model has been divided in to two parts i.e. (1) Model-1 Suklatirth to 750 m d/s of railway bridge and (2) Model-2 750 m d/s of railway bridge to Dahej-sea. He explained about the boundary conditions

34 (Inflow & Outflow water level estimate in m.) for both models for Case-1 & Case-2 for the various discharges as (1) SPF - 105689 cumecs (2) 100 year flood -77505 cumecs (3) Max. observed flood - 69384 cumecs (4) 25 year flood -57750 cumecs. He further explained the 2D modeling results for Existing Condition without barrage for Case-1 & Case-2 for Model-1 and Model-2 for the above said Discharges at different locations.

(3) Prof. Tad Murty, Chairman, SAC explained that MIKE software has better option as there are some limitation of River2D software. He further stated that more elaborate information on model calibration and validation is required. Observed water level at shown in Government Flood Manual for different flood discharges are governing factor for model calibration and validation. SAC stated that:  The Mike Flood or equivalent with structures and sediment flow would have been better option. River 2D has limitation in respect of reach length to width ratio, ability to simulate structures, ability to simulate spill over embankment, breach section of embankment and morphological changes.  Topographical data input is governed by extent and quality of data which appears to be acceptable . Use of constant HTL and MSL are used as d/s boundary, which is acceptable. In absence of appropriate hydrograph data , constant flood discharges have been used as u/s boundary condition. More elaborate information on model calibration and validation should be included.

35  Model calibration and validation will be only for pre barrage condition.

 The latest report on 1-D model for backwater studies indicate reasonable/acceptable results.  2-D model runs with sediment are yet to be taken and it is not clear whether model can simulate morphological changes.  The 2-D model studies report presented do not include results of various simulation conditions studied in 1-D model report. The structures cannot be properly simulated with the presently adapted 2D model. Therefore simulation for conditions with embankment over flow and breaching section of embankment may not be possible.

(4) EAG agreed with SAC for backwater studies of 1D model carried out by SECON is acceptable, whereas for points/ observations of SAC, M/s. SECON has to be duly complied with. If required, technical help from NIOT can be availed in consultation with Dr. N. Ghosh, National consultant.

Minutes of Agenda No. 20

Consideration of Bhadbhut Barrage Project for PPP

(1) Shri Thakkar, SE, PIU-2, Vadodara presented the details regarding Bhadbhut Barrage Project proposed under PPP mode with an option to adopt the BOT model. He explained that Government has already decided to take up the project on PPP mode and hence financial analysis is required to be carried out to assess the revenue earning potential through traffic toll and

36 industrial water sale. In this context, policy decision on some of the parameters viz. water demand, traffic toll rates, water rates, concession period, IRR etc are required to be considered for including the same in PPP tender papers. In this regard joint meeting was held on 08.06.2012 under the Chairmanship of Advisor to Hon'ble Chief Minister wherein Shri P. P. Vora, Former Chairman, IDBI and Member EAG, Shri A. K Doda Ex. Executive Director, IDBI bank and National consultant were also present. In view of the discussion, following parameters have been considered for the financial analysis. a) The Traffic study envisages the study on estimated traffic volume. Based on the rates as per NHAI guidelines and alternatively on 25% saving of VOC, the annual revenue up to year 2036 (20 years) has been worked out. The rates for the initial five years have been considered on the basis of 25% saving of VOC and from the sixth year onward, the rates are applied as per NHAI guidelines (about 50% of saving in VOC).

b) The industrial water demand study has been carried out with the projected water demand for industries in recognition of fast development of Dahej industrial area including proposed PCPIR. Water demand for industries in GIDC area and PCPIR has been supplied by GIDC and the same has been confirmed by Industries and Mines Department is considered. Accordingly the projected water demand by 2020 and onward is 1100 MLD. However for conservative analysis only 50% demand have been considered for financial analysis. The annual water demand worked out as 200 mm3.

37 c) BOT investor will get ownership for selling only 200 Mm3/ annum water to industries. The balance quantity of balanced stored water will be the GoG ownership for domestic supply, irrigation water, environment flow and future diversion to NDC for Kalpasar reservoir etc. For considerations in the tender paper of PPP mode, it is therefore proposed that if actual industrial water sale reduces below 150 Mm3/annum, Government will reimburse for the quantity beyond 150 Mm3 shortfall for that particular year and at 50% of the rate in force for that particular year. Similarly if actual industrial water sale will be in excess of 250 Mm3/annum, BOT investor has to reimburse to Government for quantity of water sale above 250 Mm3 quantity/annum at 50% of the rate in force for that particular year. It was, nevertheless, clarified that all these considerations and assumptions, as stated hitherto, are just tentative and indicative as well as subject to final decision in this regard by the competent authority.

d) As per the provision of the G.R. issued by Water Resources Department, the water rate for the year 2016 works out to Rs. 19.48 /m3 (The barrage project is planned to be completed by 2015-16.) with an increase of 10% annually. The water rates are adopted as per G.R referred to above. It is also proposed to increase the water rate by 5% after the rate is Rs. 40/m3.

(2) The project cost based on preliminary design (as discussed hitherto) is about Rs. 2900 crore.

38 As per the financial analysis, the investment of Rs 2900 crore with 17.1% internal rate of return (IRR) can be easily recovered in 20 years. Hence, the IRR 17.1% is found acceptable to pose the project on BOT model. Various options on budgetary provision and P.P.P. Options like- Annuity Model, Special Purpose Vehicle (SPV) Model and Build, Operate and Transfer (BOT) Model for implementing this project were compared and it was proposed to opt for BOT model.

The bank loan facility is generally available with payback period as 10 to 12 years. Considering 13% interest rate on debt (70% of estimated cost) of Rs. 2030 crores, the repayment period is worked out as 10 years/ 11 years.

The EAG was also appraised of various risks involved in the project viz. flood hazards, morphological changes, impact on marine fisheries and financial risk along with risk analysis and mitigation measures.

(3) (A) EAG agreed with (i) the proposal from Kalpasar department for the project to be implemented on BOT, keeping 20 years concession period but the final decision will have to be taken by the Govt. (ii) Traffic toll rate at 25% of saving in VOC is to be adopted for first five years, and thereafter at rate as per NHAI policy (about 50% of VOC) for calculation of traffic revenue. (iii) Kalpasar Department’s proposal to keep the water demand at 50% of the total demand as confirmed by the I and M Department

39 (iv) Water rates to be adopted as per W.R Department G.R in vogue with annual increment in rate by 10 % up to rate of Rs. 40 per 1000 liter and thereafter with 5% increment. (v) Government of Gujarat will be the owner of domestic as well as irrigation water, environmental flow and Narmada water diversion to NDC for Kalpasar reservoir. BOT investor will get ownership for selling only 200 Mm3/annum water to industries. But, all these being policy decisions will need to be approved by the Govt. of Gujarat before taking any further action including its implementation.

(vi) There is a possibility of wide variation in industrial water demand in PCPIR as projected by GIDC. Therefore, for such variation of industrial water quantity over the entitled 200 Mm3 quantity/annum required some policy decision is necessary. It was agreed that, if actual industrial water sale reduces below 150 Mm3/annum, (25% of the demand), Government will reimburse for the quantity beyond 150 Mm3 in short fall for that particular year and at 50% of the rate in force for that particular year. Similarly if actual industrial water sale will be in excess of 250 Mm3/annum,(25% of the demand), BOT investor has to reimburse Government for quantity of water sale above 250 Mm3 quantity/annum at 50% of the rate in force for that particular year. The final decision will obviously be taken by the Govt. of Gujarat.

(B) Shri P. P. Vora, Member, EAG, suggested to avail the services of State Bank of India Capital Market Ltd. for advice in issues pertaining to PPP mode viz. going in for PPP mode, suitable PPP model, selection of investor, evaluation of bid etc. EAG

40 agreed with this suggestion as SBI capital market Ltd belongs to SBI which is a Government bank. (C) EAG also advised the department that the above policy decisions should be adopted only after approval of GIDB or with modifications as per GIDB directives and, if needed by the Govt. of Gujarat.

Minutes of Agenda No. 21

Fixing alignment of Narmada Diversion Canal

(1) "Consultancy Services for Survey, Investigation, Preparation of design etc. for Narmada Diversion Canal" amounting to Rs. 86.60 Lacs was awarded to M/s SECON Pvt. Ltd., Bangalore. Dr Yoginarsihman of M/s SECON Pvt. Ltd explained in details how three alternative NDC alignments are selected. He has also explained merits / demerits of all these alternative alignments. M/s SECON recommended Alignment-3A for further field survey and preliminary design. He explained that alternative 1 and 2 are passing mid-way through PCPIR. Hence, entire planning of PCPIR will be disturbed. Further, it may be difficult to acquire such land. It was also mentioned that some portion (about 12 km stretch) of Alignment-3A is matching with the alignment already marked by GIDC on the development plan for PCPIR and same is also concurred by Chief Secretary on dtd. 05/12/2011.

(2) The EAG considered the work of PCPIR in Dahej which is in full swing and GIDC has already finalized the draft Development Plan of PCPIR. Hence, fixing of Narmada Diversion Canal alignment is required even for PCPIR Development Plan. EAG agreed to accept Alignment-3A as recommended by M/s

41 SECON Pvt. Ltd and acceptable to GIDC (PCPIR) only for the purpose of field survey and canal design which would be required as a part of “Feasibility Study” of the main project.

Minutes of Agenda No. 22

Appointment of Independent Engineer for Bhadbhut Barrage Project in PPP mode (1) Shri Thakkar, SE, PIU-2, Vadodara made the presentation according to which the Government has decided to take up Bhadbhut Barrage Project on PPP mode opting for BOT model. EAG also recommended that PPP is most preferable instrument for this project. He explained that as per the guidelines issued by planning commission, Independent Engineer for the construction of projects on PPP (BOT) basis is necessary. A third party having a competent technical team for scrutiny of design, approving design, preparing draft documents for PPP bids, evaluation of bids, supervising construction and co- ordinating activities carried out by BOT investor while developing, Constructing & operating the works, is required. Such agency will be required for the entire period of construction i.e. at tender stage, development stage, construction stage & operation stage and also in dispute resolution situation.

(2) It was further explained that government organizations of R & B Department have implemented many high way projects on PPP mode and normally, provision of fees and expenses to be shared equally by Government and concessionaire for the services of Independent Engineer is kept about 2% of the total project cost depending on the nature and quantum of duties

42 and services to be performed by Independent Engineer. During the discussion the details regarding role and functions of Independent Engineer for Bhadbhut Barrage Project at PPP tender stage, development stage, construction stage, operation stage in dispute resolution & other cases were explained to EAG. (3) EAG agreed for availing the services of Independent Engineer (Proof Consultants) for Bhadbhut barrage project. The RFP document and estimate of Independent Engineer prepared by the department is accepted by EAG subject to taking concurrence of GIDB/ the competent authority.

Minutes of Agenda No. 23

In the 8th EAG Meeting, EAG suggested that the possibility of utilizing the expertise of IIT Delhi or IIT Roorkee may also be explored. Accordingly, the proposals of IIT, Delhi and IIT, Roorkee have been obtained and scrutinized considering vital importance and basic parameters for dam design, TOR/estimate. National Consultant Dr. B. S. Mathur advised that the IIT, Roorkee proposal is techno- economically better than IIT, Delhi proposal. Dr. B. S. Mathur made a presentation on IIT, Roorkee proposal covering Objectives, Methodology, Deliverables, Time frame, Financial & mode of payment etc.

EAG agreed with the above proposal of IIT, Roorkee amounting to RS. 62.8 lacs + Service tax (as applicable)

43 Minutes of Agenda No. 24

Feasibility study of Railway Impact Assessment & 10.0 m wide Utility Corridors on Top of Dam

Shri R. N. Das, Manager(Traffic) and Shri M. K. Sharma, AT(T&E) of RITES Ltd, New Delhi, Govt. of India undertaking under aegis of the Ministry of Railway, presented their proposal giving details of scope of work, approach, methodology, cost estimates, schedule of payment, deliverables etc. It was informed that if single lane is proposed then, 30 trains per day in both directions can pass. For double track railway line, width of about 11 to 12 m will be required. RITES stated that study will work out commercial viability of railway lines on the top of Kalpasar dam and will examine the various alternatives of laying of railway tracks on top of dam i.e. at middle of dam or at edge of dam, as there may be possible of development of port on d/s of dam in middle of gulf in which case handling of cargo would be easier through railway. RITES’ proposal is amounting to Rs. 60.00 lacs + tax.

EAG after detailed discussion, agreed to carry out this study, as it is required even to finalise top width of dam & for estimate purpose. EAG further felt that provision of railway on the top of dam will be beneficial to railway in terms of increased revenue for passenger and goods traffic and saving in cost due to shortened route, and will be attractive proposition for railway also and could be explored as common venture development. RITES is a Central Government agency. Hence this study can be better carried out through RITES. After negotiation RITES agreed to reduce estimate from Rs. 60.00 lacs +tax to Rs. 50.00 lacs +tax, which was agreed by EAG.

44 Minutes of Agenda No. 25

Preparation of Bhadbhut Barrage Management Information System by CEPT, University, Ahmedabad.
