Amount

PART- A ( CIVIL WORKS ):- Survey, design, drawing, testing of bearing capacity, hydraulogical, geological survey and construction of water tight circular R.C.C. Dry Intake well cum pump house at the bank of river Pinder near Village Paduli with R.C.C. approach bridge of approximate 15 m length and 2.5 m width to withstand safely the river current (last 30 year)/ discharge, seismic/wind or all other natural effects and suitable for taking approximate 3.30 MLD raw water discharge(in 16 hours), including supply of all material, labour, T&P etc. required for proper completion of work. Inner diameter of well shall be 6.0 metre. Height of well is approximately 16.0 metre ( from lean water level to 2.0 M above H.F.L. of Pinder river near Paduli Village) and depth of foundation below G. L. is assumed 8.0 M, which is liable to change according to geo-investigation, structural design and site conditions and HFL of river in last 30 year. Height of pump house will be 4.00 m (including space required for Motors, HT Pannels etc.). Atleast six inlets (on different levels/heights) with a common header should be installed at/above intake floor with stainer to tap river water, pipe arrangement for drazzing pump, M. S. girder 350 mm , sluice valves as required, 1.20 metre wide balcony all arround the well shaft above HFL, doors and windows, pump foundations, internal and external electrification work, painting, distempering and snowsem all inside and outside of well, four layer M. S. railing should be on aproach bridge/balcony with hand realing and there should be 1.0 metre wide spiral stair with hand rail from pump house floor to bottom of intake. The rates should be inclusive of river diversion, all excavation required for well and bridge and dewatering etc. The overall height of intake well is taken approximately 20.00 metre from top of raft foundation to pump house roof top, which will change according to conditions mentioned above. For any increase/decrease in these heights/lengths, rates are shouted below.) The well shoud have all provisions for pumps installation of requaired capacity including all labour material T&P or as directed by Engineer in Charge.
