aspects of the Project are duly covered; that it is technically sound and that it is fit to form the basis of the contract. The following shall be particularly looked into.
I Feasibility Report Draft FS report shall be examined to ascertain that Draft FS Report is prepared meeting the requirements of Terms of reference (TOR), it is technically sound and following aspects in particular are duly covered.
(i) The consultants have a proper quality assurance system required to produce a technically sound DPR.
(ii) The consultants have made sincere efforts to collect, compile and analyse the available data on road & bridge inventory, bridge condition survey, past performance of road, right of way details, hydrological characteristics of drainage system, terrain characteristics, socio-economic features of the Project influence area.
(iii) Traffic Survey locations are fixed in such a manner that representative traffic data are obtained. Further, traffic projection is carried out in a scientific & rationale manner for realistic prediction of toll revenue and design of different elements of the Project Highway.
(iv) Indicative Design standards, methodologies and specifications conform to relevant codal provisions/guidelines, practices in similar projects in India and new technological developments that can be adopted for the Project Highway.
(v) Preliminary Widening Scheme, proposal for bypass including suggested alternate alignments are based on thorough ground reconnaissance. Objective is to select alignment of the new carriageway that meets geometries requirements, causes minimum damages to the structures, is environment friendly and cost is optimized.
(vi) The surveys, field investigations, testing are being conducted by the consultants in desired manner.
(vii) Preliminary assessment of borrow areas/quarries has been done after extensive survey and careful considerations.
(viii) Environmental & social screening data has been collected diligently to avoid hassles during implementation.
(ix) Cost estimates are realistic and based on State PWD rates, rates of similar ongoing projects etc.
(x) Parameters of financial and economic analysis have been adopted conforming to implementation strategy of the Project.
(xi) Based on peer review of Draft FS Report, suggestions/ recommendations are to be given for improvement of the further activities of DPR work. II Scope of Peer Review of DPR
DPR shall be examined to ensure that all aspects of the Project are duly covered, that it is technically sound and that it is fit to form the basis of the contract. The following shall be particularly looked into.
(i) DPR should be faithful to site conditions, availability of materials, and capable of translation on the ground. Survey control points on ground should be established physically and securely and in sufficient numbers to allow accurate and convenient setting out of works.
(ii) Hydraulic design parameters should be based on correct data and field survey. Sub-soil investigation for design of structures, sub-grade soil and material investigations for design of pavements should be accurate and reliable and in sufficient detail. The information should be tabulated and also represented graphically in a form that is capable of being checked and verified. Due account should be taken of any environment restrictions.
(iii) DPR should identify the potential sources of materials, like quarry sites, borrow areas, establish their quality and recommend their use on the basis of techno-economic principles.
(iv) Correct details of all physical features and obstructions, structures, railway lines, canal/river crossing, water mains, sewers, gas/oil pipes, trees, plantations, electric and telecommunication lines etc. which affect the proposal should be marked to an accuracy/tolerance consistent with their likely interference.
(v) Utilities relocation plans should be prepared in consultation with the authorities concerned.
(vi) The drawings should be capable of execution at site without additional instructions or changes.
(vii) The pavement design should take due account of the characteristics of materials to be used in various courses, and the variability of their properties. The report should also forecast, in terms of time and traffic, the deterioration levels at various stages of pavement life, and suggest the required maintenance strategy.
(viii) Drawings for ROBs/RUBs should be based on clearance by and approval of concerned Railway authorities.
(ix) In case of bridges, the final design should be based all approval of Genera Arrangement Drawing (GAD) and alignment plan by NHAI, to be given after consideration of alternatives bringing out their cost effectiveness and ease of construction.
(x) The description of items in Bill of Quantities should be consistent with the drawings and specifications, and all should lend themselves to harmonious and unambiguous interpretation.
(xi) Besides the quantities of various items of work, BOQ should also give the quantities of major materials like, cement, steel and bitumen likely to be required for the work in order to arrive at their reliable percentages, required to be given in the Price Adjustment Formula.
(xii) The requirements of road safety, the necessity for felling of trees, the local consultations had by DPR Consultants (with a view to identifying the needs/expectations of the people regarding, underpasses/realignment etc. keeping in view the codal requirements) etc. may also be reviewed.
