hemadhri surveys

Hemadhri Surveys did a detailed topographical survey of 420 km for the gas pipeline, Including Alignment, L-Section, TBM Fixing, Alignment on the ground.

We did a field survey for the proposed water pipeline, captured topographical details with geo-coordinates, located different water tanks and prepared a proposed alignment route map along with the village boundary map.

Collected 3 to 5 Nos of Ground Control Points (GCPs) with dual frequency DGPS in RTK Mode at each site in villages, Including painting of monument and 3 photos for each GCP.

Field survey along the bank of Najafgarh Drain 10 meters corridor on either side of 55 km line.  Captured all sub-drain locations with geo coordinates.  Collected cross-sectional details and invert levels of all the drains. Carried out a  topographical Survey along the main drains inclusive of the corridor of 10 meters on both sides of the drain.

Performed DT Leveling survey using Digital levels for providing height control in MSL datum over the project area a total of 2430 km covered in our survey

Fixed of pair of GCPs at every 5km with DGPS and Transferred the GTS Benchmark with Digital Level. Traversed survey area with Total Station. Collected Longitudinal levels along the alignment every 20 meters interval with cross-section at every 20 meters with Total Station. Collected all existing structures along the pipeline alignment such as government schools, religious structures, ponds, electrical poles, etc. Collected existing OHSR, GLSR, Sumps and cisterns. A total of 500km was covered in the survey.
