Military Engineer Services Tender

Material and labour for earthing complete with copper earth plate electrode of size 600 x 600 x 3.15mm thick buried directly in ground with earth pit not less than 2.25 meter deep below ground level with top edge of plate not less than 1.5 meter below normal ground level connected to copper strip of size 20 x 3mm earth lead by means brazing after fixing of nuts, bolts, check nuts, washers of galvanised iron steel, protected by galvanized iron pipe 40mm bore (medium grade) all as directed including cement concrete (1:3:6) type C-1 earth pit with precast RCC (1:1.5:3) type A-1 cover slab of size 42 x 42 x 6cm thick reinforced with 8mm dia TMT bars @ 15 cm c/c both ways with 10mm dia mild steel round bar of 30 cm long, bent to shape as lifting handle, funnel, wire mesh, 20 mm bore galvanized iron pipe (medium grade) for watering, earth testing point, charcoal or coke and salt in alternate layers with necessary earth work in soft/loose soil complete all as shown in electrical plate No 3 of SSR Part I including testing on completion including taking down old existing unserviciable earthing complete all as specified and directed. Note:- Strip upto 7.5m length including testing shall be included in quoted rates.

Supply and installation of advance encapsulated compound based CPRI tested maintenance free, pipe-in-pipe technology upgraded (zinc & alloy coated), zinc coating ( 80-100) microns with pure zinc (99.9%) & alloy coating (200-250)microns. Earthing system conforming to IS-3034, ASEEL-39. The outer and inner pipe should be 76.2 mm & 41.9 mm, 3mtrs length, zinc coated with additional special alloy coating 300mm on the top side for additional corrosion protection of the terminal. The annular space between the pipes being filled up with COMPACT FILL(CF) (Crystalline Conductive Compound). The COMPACT FILL (CF) mixture which is machine pressed in the pipes should not disintegrate or collapse when outer pipe corrodes. The inner pipe should be extended with terminals for connectivity. The job includes digging the pits of dimension 60cm X 60cm up to depth of 3.1m and replace the soil with low resistive soil as approved by Engr-in-Charge, then make a bore of dia 200mm of depth 3.1m and refilling the same by conductolite back fill compound (Ground Enhancer), the BFC should be eco friendly it should not contain environmentally hazardous material / metal having RoHS Certification from NABL accredited lab. Good earth is to be arranged to fill the excavated pits by mixing the same with BFC 2 bags (conductolite) including FRP (Fiber reinforced plastic) light weight, high mechanical strength, chemical resistance with detachable easy locking lid of size 250mm X 250mm of thickness 2mm and the earthing should be installed by applicator of the manufacturer / authorised dealer including taking down old existing unserviciable earthing complete all as specified and directed.
