Data Collection of Existing Project DPR Surveys Reconnaissance Survey Pavement Condition Survey Material Survey Pavement Structural Evaluation Topographic/Levelling Survey Traffic Surveys Inventory and Condition Survey of Bridges and CD Structures Engineering Design Cost Estimates
DPR Survey Formats Reconnaissance Survey Methods The reconnaissance survey methods may be conducted in the following sequence: a) Study of topographical survey sheets, agricultural, soil, geological and meteorological maps and aerial photography. b) Aerial photography wherever necessary and feasible, and c) Ground reconnaissance including another round of serial reconnaissance for inaccessible and difficult stretches, where required . Reconnaissance survey is generally not required for the work consisting of improvements to existing roads unless bypass roads are involved.
Reconnaissance Survey Reports: Based on information collected during the reconnaissance survey, a report should be prepared. The report should include all relevant information collected during the survey and a plan to the scale of 1:50000 showing the alternative alignments studied along with their general profile and rough cost estimate. It should also discuss the merits and demerits of the different alternatives to help the selection of one or more alignments for detailed survey and investigation. Cont.…DPR Survey Formats Road Inventory and Pavement Condition An inventory of the project road has been carried out by visual observations supplemented with sample measurements using tape etc. Kilometer wise features like terrain, land-use, pavement surfacing type and width, shoulder surfacing type & width, Subgrade, local soil type, curve details, retaining structures details, location of water bodies, height of embankment or depth of cut, ROW, CD structures, road side arboriculture, existing utility services and general drainage conditions etc. were recorded. The road inventory has been referenced to the existing KM posts established along the roadside.
Material Survey Soils and materials investigation for a road project is an essential requirement for design and construction. During design stage of the road pavement, embankment and other structures, the existing soils and materials inventory is needed for their characteristics, availability of required quality and sufficient quantity for construction at reasonable cost. The project will require different type of construction materials, which include: Soil for embankment, subgrade and shoulder Granular materials for sub-base, drainage layer and backfill Stone aggregate and sand for pavement courses and cement concrete works Water for use in construction especially in case of cement concrete Grain size analysis : As per IS: 2720(part 4) Atterberg limits : As per IS: 2720(part 5) Moisture-Density test(Heavy Compaction) : As per IS: 2720(Part 8) CBR (Unsoaked, and 4 days soaked) : As per IS: 2720(Part 16) Aggregates tests : IS: 2386(part-4) : 1963, IS: 383-1970, Is 5640 – 1970 Bitumen Binder:: IS: 1209 – 1978, IS: 73 – 2006.
Pavement Structural Evaluation The structural strength evaluation of the existing pavements was carried out as per IRC 81: 1997. Pavement sections were cut open from the surface up-to the subgrade level and subgrade soil samples were collected in water proof bags for determination of moisture content, wet sieve analysis to determine classification of soil and also to determine the Consistency limits. Plan of Study Field Studies – BBD studies, Unevenness studies Topographical Survey Topographic survey using total station equipment was conducted and a contour map shall be prepared showing contour line drawn at an interval of 0.5m, it also indicate all the prominent existing features such as roads, railway tracks, colonies, (independent houses also), power lines, water bodies, farms, gardens, fields etc. Few reference stones were marked on the survey map and their levels were enlisted (smaller to larger scales). Providing and fixing of boundary stones at an intervals of 50m and additionally wherever bends occurs was done as per the directions of Engineer In charge. Block levelling Office processing Test pit investigation survey Sub soil investigation Hydrology and Drainage Investigations
Traffic Surveys Estimation of traffic over the project corridor is an essential step towards establishing the project viability; the objective was to assess the prevailing traffic characteristics. This includes conducting field traffic surveys, data analysis, estimation of local traffic and diverted traffic. The present traffic surveys have been planned in a way to obtain all the necessary information and data deemed necessary for development of the project. Traffic Volume Studies Spot speed studies Speed & delay studies Parking studies Accident studies

Engineering Design Analysis of data collected during various engineering surveys/investigations and the formulation of improvement proposals including planning and design of various project components are included in DPR. Geometric Design of Highway The geometric deficiencies of the project road will be identified from the topographic surveys and improvements will be proposed accordingly, keeping in view the design standards, practical feasibility and land acquisition consideration. Generally, design speeds for Hilly terrains 50 kmph have been adopted. Since Realignments are not proposed, shifting of existing alignment being proposed in the poor geometric sections for improvement of geometrics to be in conformity with the IRC guidelines. Pavement Design The pavement design includes Overlay design of the existing pavement Benkelman Beam Deflection Test Results and Pavement Condition Survey data as well as close reconnaissance by experts were used to determine the strengthening requirement of existing pavement. The thickness of overlay was proposed judiciously considering the provisions of IRC: 81-1997. Based on Design wheel load, Grade of Concrete, Traffic Intensity, Thin White topping overlay has been designed as per IRC: SP: 76-2015.
Preliminary Cost Estimates The rate of materials adopted in the preliminary cost estimate is based on the basic rates of PW, P & IWTD S.O.R. For items where these rates are not available, the rates were adopted as per Market rates. For the working out of preliminary cost estimate, work items are split into the following sub-heads: Site Clearance and earthworks Granular Pavement Courses Asphalting Works Culverts, Retaining Walls and other structures Drainage and other Protective works Road Furniture and Road Safety Works Traffic Management and maintenance during construction
STAGES IN PROJECT PREPARATION The stages involved in the preparation and sanction of road projects are: a) Pre-feasibility study The pre-feasibility study is necessary to enable the funding agency to appreciate the features of the project. This is to be done based on reconnaissance survey by collecting information based on the present status of the road and the anticipated traffic after development/improvement b) Feasibility study /Preliminary project report preparation The feasibility study is intended to establish whether the proposal is acceptable in terms of soundness of engineering design and expected economic benefits from the project for the investment involved. c) Detailed engineering and plan of construction Detailed engineering covers detailed alignment surveys, soil and materials surveys, pavement design studies, drainage studies, environmental management plan based on environmental impact assessment studies (if required), detailed drawings, estimates and implementation schedules and documents.
