:BB masonry Providing second class Burnt Brick masonry with conventional/ I.S. type bricks in cement mortar 1:6 in foundations and plinth of inner walls/ in plinth external walls including bailing out water manually , striking joints on unexposed faces, raking out joints on exposed faces and watering etc. Complete 889

:Sand faced plaster Providing sand faced plaster externally in cement mortar using approved screened sand, in all positions including base coat of 15 mm thick in cement mortar 1:4 using waterproofing compound at 1 kg per cement bag curing the same for not less than 2 days and keeping the surface of the base coat rough to receive the sand faced treatment 6 to 8 mm thick in cement mortar 1:4 finishing the surface by taking out grains and curing for fourteen days scaffolding etc.complete.963

Waterproofing treatment to new terrace by using chlorinated paraffinated talcum polyurethane (CPTP) elastomeric membrane as approved by Engineer in charge, followed by average 112mm thick brick bat coba covered with 40mm thick IPS. The procedure includes filling of cracks on the RCC slab with high performance polyurethane (liquid applied) membrane. Clean the entire surface thoroughly and over this prepared surface, apply a primer coat of high performance polyurethane (liquid applied) membrane as approved by Engineer in charge. Apply the primer by roller. Extend the coating to parapet walls including the top of parapet. Allow the primer coat to set for 24 hrs. After the primer coat is set, apply two coats of chlorinated paraffinated talcum polyurethane (CPTP) elastomeric membrane as approved by Engineer in charge on surface. Ensure that pinholes are touched up properly. While the second coat of high performance polyurethane (liquid applied) membrane is wet and tacky, sprinkle coarse sand over the surface to make it rough and provide mechanical key for further treatment. Provide and lay average 15 mm thk protective coat of CM in 1:4 over the surface and allow to set and cure. Provide and lay 112 mm thk BB coba in average thickness in cement mortar 1:5 with one pouch of thorough blend of special cements, aldehyde based polymers, shrinkage compensating agents - which is based on special cements, aldehyde based polymers, shrinkage compensating agents and selected sands having high abrasion resistance as approved by Engineer in charge per 50 Kg bag of cement and finishing with 40 mm thick IPS layer in M-20 CC by mixing one pouch of 330 grams of thorough blend of special cements, aldehyde based polymers, shrinkage compensating agents per 50 Kg bag of cement, including all leads, lifts and laid to proper slope to drain off water entirely preparing bell mouth including watta, beveled or champhered portion at the junction of parapet and work up to a height of 300 mm or as directed and including finishing the top layer of waterproofing treatment with false marking of 30 cm x 30 cm or as directed, curing and covering the whole treatment. The liquid membrane should have a track record of atleast 4 years in India & Gulf region and have atleast an 4 year track record in PWD. Single Component, Liquid Applied, chlorinated paraffinated talcum polyurethane (CPTP) elastomeric membrane should have following minimum properties: 1) Water Permeability (DIN 1048): Nil as per DIN 1048 @ 7 bar of Hydrostatic Pressure. 2) Moisture Permeability: < 0.4 g/m2/day 3) Accelerated Weathering (IS 101): 2000 hrs No cracking or blister formation 4) Adhesion to concrete (ASTM D 1000): >21 Kg/cm2 (Concrete Fails) 5) Tensile Strength: > 2.0 MPa (ASTM D412) 6) Should not be water soluble or water dilutable 7) Shore A Hardness: 40 ± 5 (ASTM D2240) 8) Elongation at Break: > 900 % (ASTM D412) 9) Solids: > 95 % 10) No micro-bubble formation or blistering should take place during the curing of thick films.

Providing and fixing mild steel grill gate with angle iron frame 65mm x 65mm x 10mm with iron bars at 150mm C/C and diagonal flats as per the detailed drawing including hinges, pivot block locking arrangement, welding riveting and oil painting of three coats of approved shade Weight of gate 35 Kilogram/Smt.
