renovation of physical research lab no.2 on 2nd floor of department of chemistry in p.u. c us sector-14, chandigarh. , civil work , providing and fixing wall table ( 13-8 x 2-3 x 2-9) it shall be 20mm (+/- 2mm) thick jet black granite worktop. the exposed edges of the worktop should be chamfered and smoothened. the bottom of the worktop should be polished and there should be a v-groove throughout the length of the exposed edges to protect the cabinets from coming in contact with the spillages. the overhang on the storage cabinet is 25 mm at the front side and 25 mm at the sides the suspended under-bench welded units should be supported on heavy-duty steel frames fully carrying the load of worktops. its superior strength combined with aesthetically appealing end caps shall give maximum flexibility and modularity while making a layout. d-frame should be constructed from a square pipe with a cross section of 30mm x 30mm and should be a minimum 1.6 mm thick. the d-frame legs should be supplied with adjustable levelling screw (m-10 levelers of nylon + ms, tolerance from -5mm to +15mm) to correct the unevenness of flooring. the tubular enclosed type construction shall discourage dust accumulation and unwanted development of bacteria & fungus. drainage gradient should be well adjusted throughout the length of table and should have horizontal supports for drainage systems. it should be suitable for sitting and standing nominal heights of 750mm & 900mm respectively. the nominal table depths should be 450mm, 600mm, 750 mm for wall side and 1050mm, 1200mm, 1500mm for island tables.

such as top, bottom and stiffeners should have a minimum thickness of 0.8 mm and drawer separator should be of 1.2mm thick. shelf : should be made of 0.8mm thickness which should be adjustable to 6 steps of 50mm. shutter should be over-closing type. it has a sandwich door construction with shutter front & shutter cover with 1.2mm thick hinge stiffener. empty gap should with filled with 15mm thick paper honeycomb for sound ampening.drawer: should be welded single piece construction with over-closing sandwich drawer front filled with 15mm thick paper honeycomb for sound dampening.units should be in 450mm and 600mm widths.used for housing electrical switches and sockets, its top panel, bottom panel of the trunking should be made from minimum of 0.8mm thick body. it should be available in both, single sided and double-sided configurations. it should be made from crca ms with pure epoxy powder coating. the front surface that houses the electrical points should have a slope.
