  2. Contents • Tendering • Planning • Execution • Monitoring • Billing • Costing & Budgeting

  3. Tendering

  4. Tendering • First of all “Authority / Client” invites tender proposal based on initial survey or feasibility report done by consultants hired by the authority. • Types of Contracts: • There are different types of contracts for highway works, out of which any one chosen by the client based on feasibility report. Various types of contracts are as under: • EPC Contract : EPC (Engineering, Procurement & Construction) contracts are in which the contractor execute the work as per specifications with own procured materials and claims periodically bills to the clients for his work done as per item rate BOQ. • After completing the project there is the provision of maintenance period for which the project should be maintained by the contractor with or without any cost as described in the agreement.

  5. Tendering • BOT (Toll) / DBFOT Contract : DBFOT (Design, Built, Finance, Operate and Transfer) contracts are in which the contractor called concessionaire which may be the SPV (Special Purpose Vehicle) who is responsible for • Design the work as per specification & contract normally the concessionaire engaged design consultant for this purpose. • Execute the work as per specifications & design normally the concessionaire choose the EPC contractor for the execution. It may be his own subsidiary or any other company which execute the work as per EPC contract. • Arrange the Finance for the project. Detail financing elaborated further. • Contd………

  6. Tendering • BOT / DBFOT Contract Contd….. • Operate & collect the toll for the stipulated concession period (it may be 10 to 30 years as per contract) and recover his expenses with interest and after that his profit. Within this period the concessionaire also responsible for the maintenance of the road. • After completion of concession period the highway stretch will be transferred to authority / client.

  7. Tendering • BOT (Annuity)/ DBFOT Contract : All the procedures are same as described for BOT (Toll) the only difference is that instead of toll collection the authority disbursed fixed Annual Amountupto the concession period as per the agreement (2 installments per year). • This type of contract awarded where traffic volume is less & toll collection is not viable.

  8. Tendering • OPRC Contract : Output and Performance-based Road Contracts is the new contract type mainly used for the world bank projects. This is same as EPC contract but the difference is the EPC contract has an itemized BOQ and its rate and OPRC has lump-sum deliverable item based rate. Also for this type of project first step is for financial bid and second is for technical bid which can be qualify by only the contractor who have given good output and better performance in their previous works.

  9. Tendering Execution cycle for a EPC Contract Site Visit & Cost Estimation Project Awarded Pre- qualification Financial Bid Proposal of Bid Letter of Acceptance (LOA) Execution of Project Signing of Agreement Pre-construction Activities Project Planning Work Execution Project Completion & Handover Periodic Billing Finishing Works Final Bill

  10. Tendering Execution cycle for a BOT(Toll)/DBFOT Contract Site Visit & Cost Estimation Traffic Survey & Forecast Financial Model Pre- qualification Proposal of Bid Letter of Acceptance (LOA) Signing of Agreement Financial Closer Project Awarded Financial Bid Toll Collection & Maintenance for entire Concession Period Project Completion & Commercial Operation Project Handing over to the client Awarding & Execution of EPC Contract

  11. Tendering Financing the BOT Projects EPC Cost/ Construction Cost Non -EPC Cost / Non-Construction Cost (IDC, Financing charges, consultancy etc.) Total Project Cost (TPC) Equity (To be infuse by the Concessionaire) Debt (To be taken as loan from banks) Grant (To be infuse by the Client) Grant is the part of amount which the client is to be infuse in the project but now a days some projects have negative grant or it called premium which amount concessionaire gives to the client / authority from the project.

  12. PLANNING

  13. Planning Macro Planning • This is an initial work plan at the time of starting of the project to find out the better way for working with major sections and items. • it is a base programme for further planning. • It can be submitted to the Client / Consultants.

  14. Planning Micro Planning • This is a detail work plan for execution of work which includes all the activities linked with each other with appropriate relations. • What we can do with this: • Finding out the critical tasks. • Plan for utilization of our resources. • Anytime execution detail. • Anytime requirement of Equipments & Materials. • After updating the programme we can know the delay and find out the better solution to finish the work in time.

  15. EXECUTION OF WORK

  16. WORK EXECUTION Pre-Construction Activities • Before starting the construction activities, we have to do some pre-construction activities as follows: • Camp / Office Construction. • Survey & Alignment works. • Establishment of Plants and mobilization of Equipments. • Appointment of Key personals & supporting staffs. • Finalization of Design & Drawings (For DBFOT projects). • Land acquisition status and pressurize the authority if acquisition balance. • Removal of encroachments. • Shifting of utilities apart from ROW.

  17. WORK EXECUTION Construction Activities • We have to execute the work as per design & drawings. To quantify & bill the executed work we have BOQ (Bill of Quantity) for every project. Generally the BOQ item heads for Highway projects are as follows: • Item No. 1 – Site Clearance – C & G, Dismantling, tree cutting, stump removal etc. • Item No. 2 – Earth Work – Excavation (Soil, rock etc.), Earth Filling (Embankment, Sub-grade, Shoulder, Median etc.) • Item No. 3 – Sub-Base – Granular Sub-Base (GSB), Wet Mix Macadam (WMM), Drainage layers etc. • Item No. 4 – Bituminous Course – Primer, Tack Coat, BM, DBM, BC etc. • Item No. 5 – Structure Works – Cross-Drainage (CD) works, Culverts, Bridge, ROB, Under Pass, Grade-separators etc. • Item No. 6 – Drainage & Protection – Road side drains, Pitching, Turffing & other slope protection works. • Item No. 7 – Junctions – Junction improvement works. • Item No. 8 – Traffic Signage, Marking & Other Appurtenances - Kerb, Km stones, Signage, Road Markings, Guard rails, Crash barriers etc. • Item No. 9 – Miscellaneous Works – Photographs, Lightings, Signals, Cars, etc. • Item No. 10 – Maintenance Work – Pot – hole repair & Existing road maintenance. • Item No. 11 – Toll Plaza – Toll plaza building, Booth & All provisions ( BOT Projects)

  45. MONITORING

  46. Monitoring Monitoring is an essential part of any project. To know the progress of work and to plan further action daily progress have to be monitored without fail. Daily Progress Report • This is a daily basis report of work done at site with all the details showing physical progress, financial progress, equipment and manpower utilization etc. (It will be generated at the site and sent to Corp. for further information & utilization) • What we can do with this: • All the functions of PMC are depends on this report. • All other reports like weekly progress, monthly progress, status of highway and structures can be made with this. • It will helps to update the work programme. • It’s summarized report can be send to upper Management for daily progress review.

  47. Monitoring Monthly Progress Report • This is a detail report about monthly status of the project comprising with upto date Physical & Financial progress and overall project status as on date with some graphical charts. • What we can do with this: • Based on this report we can prepare the MPR for Client / Consultants. • This report will show the overall status so that we can plan our further step. • It will show us the actual status of hindrances and other problems for the project. • It will helps to update the work programme.

  48. Monitoring Updating Highway Strip Chart • Highway is a linear part of the project so the progress can be monitor with the strip chart with all the major layers. • What we can do with this: • It will show the physical progress of Highway works at a glance. • It will show the Hindrances / Land availability status. • With the help of this chart we can calculate the work done and balance quantities of highway. • It will help to know the linear progress of all the layers.

  49. Monitoring Updating Structure Strip / Pictorial Charts • To know about the structure wise progress at a glance this is the best way to maintain the pictorial chart for individual structures. • What we can do with this: • It will show the physical progress of Structure works at a glance. • With the help of this chart we can calculate the work done and balance quantities of Structures. • It will help to know the actual status of structures and to finalize the further step for structure progress.

  50. Monitoring Other Reports • Some other report which can help for monitoring the projects are as follows : • Daily Manpower Status : It will show the status of manpower present at site and further requirement if any. • Daily Equipment Status : It will show the status of equipments deployed at site, working, idling and breakdown status and further requirement if any.
