India Optel Limited Tender

S&F for Plates (plain or chequered) channels, square cut or notched (ordinary and counter sunk) forming holes, without any attachment with riveted, bolted or welded attachment.Fe- 290 (Gde E- 165)

S&F of PVC SWR bend110mm.

M&L for (i) Surface preparation: The concrete substrate must be sound and of sufficient compressive strength (minimum 20 N/mm2) with a minimum pull off strength of 1.5 N/mm2 for durable and lasting flooring. The substrate must be level, clean, dry and free of all contaminants such as dirt, oil, grease etc. All previous floor coating if any must be mechanically removed to the maximum extent possible. It is acceptable to relay on floor coating that has a firm bond (pull out strength of 1.5N/mm2). Concrete substrates must be prepared mechanically using abrasive blast cleaning, scarifying or grinding equipment to remove cement laitance and achieve an open textured surface. Weak concrete must be re moved and surface defects such as blowholes and voids must be fully exposed.Repairs to the substrate, filling of blowholes/voids and surface leveling must be carried out using appropriate repair product. The concrete or screed substrate has to be primed or leveled in order to achieve an even surface. High spots must be removed by grinding. (make: MYKarment, fosroc or equivalent) (ii) Providing and installing Myk Arment 6mm thick Polyurathene flooring using FloArm Top HPU 6 , 4 components with outstanding wearing properties self smoothing heavy duty polyurethane flooring, mixing 4 components by mechanical means,mixed screed FloArm Top HPU 6 (Thickness 4.0 mm) over completely dried coats of FloArm HPU Sc as Scratch coat etc spreading the mix using trowel, including surface roughening, groove cutting, cleaning, groove filling using FloArm Top HPU 6 allowing it to dry completely, etc and complete as per manufacturer's specification. The parameters for FloArm Top HPU 4 are as follows: Compressive strength (IS9162-1979) Approx. 53 N/mm² (BS6319) Tensile strength (IS9162-1979) Approx. 7 N/mm², Flexural strength (IS9162-1979) Approx. 12 N/mm², Adhesive pullout bond strength in N/mm² (ASTM D 4541-2002) 1.5 N/mm² (concrete failure) Taber abrasion resistance (1000 g, 1000cycles) (ASTM D4060) weight loss, mg CS17 wheel: 125, H22 wheel 1500, Shore D Hardness 75 Slip resistance (under BS 8204: Part 2: 2002(9),wet and dry ) Satisfactory Impact resistance (under BS 8204: Part 1: 1999) Satisfactory Water absorption 0 ml, Surface spread of flame (BS 476: Part 7) Class 2 Foot traffic @ 30degC After 36 hrs, Light traffic @ 30degC After 48 hrs, Full traffic @ 30degC After 60 hrs, Full cure @ 30degC After 7 days (make: MYKarment, fosroc or equivalent). The laying of matrial shall be got done through the authorized applicator of the maunfacurer. OFCd will verify the same while execution of work. (iii) Providing and cleaning of pot holes with wire brush and cut the groove of damange portion and fill it with MYK ERM (Epoxy Repair Mortar) FloArm ERM is a three-component filled epoxy (make: MYKarment, fosroc or equivalent)
