Pipe Railing around Staircase (both sides), Balcony & Top Dome Periphery, S.S. Ladder from Opening of Top Dome to Bottom Dome, Staircase (Separate Two-Column Based RCC Staircase including Escape Channel of 20 m Length, Box-Type Enclosure at the Entrance of the Staircase having Locking Arrangements, and 1.20 m Wide Balcony), Food Grade Epoxy Coating on Inside Surface Area of Water Container after Successful Testing for Water Tightness as specified on the page No.- 194 of Tender Document for Following Capacity and Staging mentioned as per BOQ. For bidding purposes, the bearing capacity of soil shall be considered as 8 t/sq.m. Working design shall be based on the SBC determined (The depth of bore hole shall be two times of proposed dia meter raft foundation of OHT) after soil investigation / 8 tonne/sq.m. The depth of foundation is minimum 2.50 m from existing ground level on raft foundation or pile-cum-raft foundation or at more depth based on the design of the tank, for which no extra claim shall be entertained. The height of columns shall be desided by considering the natural ground level and formation level of floor of OHT. The staging shall be accounted between floor level to bottom ring beam. Note: The bid price of Overhead Tanks is to be submitted considering net safe allowable bearing capacity as 8 t/m², keeping the minimum foundation depth to be 2.5 m below the existing ground level at the site of work. The successful bidder will be required to investigate the soil bearing capacity. If net safe allowable bearing capacity is found to be equivalent to or more than 8 t/m², the design of OHT will be based on 8 t/m² capacity. However, in case the net safe allowable bearing capacity is found to be below 8 t/m², then the design of OHT will be based on the actual bearing capacity, adopting raft foundation or raft-cum-pile foundation.

Construction of CWR: Design, soil investigation, submission of IIT-vetted structural designs and drawings, supply of all materials, labour, tools & plants (T&P), and construction of Clear Water Reservoir (CWR) cum Pumping Station of required capacity including freeboard, as per approved drawings, IS specifications, and directions of the Engineer-in-Charge. The work includes site clearance and development, excavation to required level, bed preparation, construction, refilling and compaction; fixing of inlet, outlet, overflow, washout and other pipes of suitable sizes; stainless steel manhole covers with locking arrangement, ventilators, and suction level indicator; drainage arrangement for complete emptying of CWR for cleaning, repair and maintenance; RCC staircase from top slab to raft foundation/bottom with SS-316 handrails on both sides. Application of food-grade epoxy coating on internal surfaces shall be done after successful water-tightness testing. Provision shall be made for gantry beams or gantry slabs with adequate height and clear space above the gantry, to be finalized during the design of the pumping station. The minimum height of the pumping station shall not be less than 6.5 metres. A rolling shutter shall be provided for the smaller span of the pumping station, and a main gate shall be provided at the longer span.The top surface (roof) of the Clear Water Reservoir, as well as the roof surface of the pumping station, shall be finished with 40 mm thick Kota stone flooring. Provision shall be made for laying electric cables from the motor to the starter in trenches provided within the RCC slab of the Clear Water Reservoir. Open trenches shall be covered with MS chequered plates. During structural design, it shall be ensured that all cables, PVC pipes, and any other electrical or mechanical arrangements required for installation are accommodated within the trenches, without obstructing the floor or other structural elements. The pumping station size shall be decided based on the number of pumping plants, keeping space for a control cabin of minimum 3 m width with uPVC & glass panels, required furniture, and one air-conditioner for SCADA installation. A minimum 3 m × 3 m verandah on 400 mm dia RCC columns shall be provided at the entrance of the pumping station. Provision of two 60-W solar lights with dry battery shall also be made. The external surface of the Clear Water Reservoir up to the ground level shall be painted with bituminous epoxy coating with a minimum thickness of 1000 micron. For bidding purposes, the Safe Bearing Capacity (SBC) of soil shall be considered as 8 t/sq.m. Working design shall be based on SBC obtained from soil investigation or 8 t/sq.m, whichever is lower. Depth of borehole shall be twice the proposed diameter of raft foundation. Minimum foundation depth shall be based on structural design. The clear height of CWR from formation level of the campus shall be minimum 60 cm. on raft or pile-cum-raft foundation, or deeper as per design, with no extra claim on this account. All works complete.
