PART - B (NON DSR ITEMS)

The survey works shall be carried out to facilitate comprehensive planning and design of infrastructure including buildings, internal roads, culverts, surface drainage, and overall site development. The work shall be executed using modern survey techniques to achieve high accuracy and detailed topographic information. Necessary site clearance also to be done to execute the survey work if required . 1. Topographical Survey • Conduct detailed topographic survey of the entire project area using Total Station, GPS/DGPS, and Auto Level instruments. • Mark all existing physical features such as: o Natural features: Trees, ground undulation, water bodies, low-lying areas, rock outcrops. o Man-made features: Existing buildings, roads, drains, utilities (OH/UG lines, poles, pipelines). • Preparation of contour maps at suitable intervals (preferably 0.25 m to 0.5 m) for assessing terrain profile and gradient. 2. Boundary Survey and Demarcation • Demarcate the boundary of the land parcel with reference to existing land records or revenue maps. • Fix permanent benchmarks and reference pillars using concrete/masonry pillars for future referencing. • Record the geo-coordinates (latitude, longitude, elevation) of boundary points.
