Surveying for planning of proposed water treatment scheme at Karmatang-X Nallah under Sub Division No.I, NACD, APWD, Mayabunder.

Amount

Conduct of Total Station Surveying including mobilization of survey equipment, men and materials to site, local transportation to site, conduct of open traverse survey along the nallah and adjacent land to a width of about 10m on both sides of nallah, providing levels at cross sections at 10m interval and closer intervals at curves, taking levels at the bed of nallah where water stagnation is available. Plotting to convenient scale and furnishing 04 sets of Auto Cad drawings complete as per direction of Engineer-in-charge.

Planning of suitable weirs at two location across the nallah in consultation client including proposal for widening of nallah near the weir site as per the feasibility at site, to maximize the storage volume, supplying of working drawings of the proposed weir sections, visit of consultant to site to familiarize the ground situation and attending meeting with the Engineer-in-charge about the possible alternatives before finalizing the planning.

Preparation of cross section at 10m interval along the route of nallah, proposing proper river training works by adopting proper side slopes and proposing regular geometry to maximize the flow and storage of water, computation of volume of earthwork in excavation and banking, computation of storage volume of water for both the weir locations, providing 04 sets of Auto Cad drawings and computational sheets in hard and soft copies complete as per direction of Engineer-in-charge.
