Scope of Work:
GPR Investigation to map the underground Pipelines, identification, and reporting, underground utilities alongside the road 1.1Km at mentioned location..
MUMBAI COASTAL ROAD PROJECT (SOUTH), Mumbai, India.
HCC-HDC JV (HINDUSTAN CONSTRUCTION CORPORATION & HYUNDAI DEVELOPMENT CORPORATION).
GSSI SIR-4000 equipped 400 MHz, 200MHz, 100MHz antenna.
Large number of junctions, heavy traffic, executed at night-time.
The utility mapping and GPR survey has been carried out at location Mumbai costal road in two separate stretches approximate total length 1:1 km, on Khan Abdul Gafar Road and its adjacent promenade areas at Mumbai Coastal Road with average width of 10m. The scope of this project is to map all type of Utilities, metallic as well as non-metallic including water and gas pipelines, sewer lines, cables, storage tanks etc. around 6m and 3.5m across and along the direction of the road using non-destructive Ground Penetrating Radar technology. The purpose of the project is to map all underground utilities in order to prevent the damage to the same during the construction proposed. Considering the client's requirements and the expected depth of the utilities, the area has been surveyed using GPR technology by 400 MHz & 200MHz centre frequency antenna mounted with SIR 4000 GPR system to cover the depth up to 3-4m with fair resolution. A plan view along with sectional views have been generated with marked identified utilities. the located utilities were differentiated as metallic and non-metallic and classified as per ASCE standards.
