Providing and fixing of facade at all heights with extruded hollow Clay / Terracotta ventilated rainscreen tiles of height 250/ 300/ 400mmand length of 595 mm of approved texture,design and pattern having Flexural Strength/ Modulus of Rupture of > 14 N/m2 and maximumwater absorption of 10% tested as per ISO 10545-4:2004(E) and ISO 10545-3:1995 respectively in true level fixed to a supportingaluminium framework(Alloy 6063 T5/T6) consisting of vertical 'T' (for intermediates)/ 'L'(for ends/ termination)/ Tubular sections (atcorners)of size 80x60x2mm/ 40x60x2mm/ 40x40x2mm respectively, spaced at maximum spacing of 600mm c/c matching to the tilevertical grid, and horizontal aluminium 'C'- clamps of size 56x25x2mm thickness of length 150mm at junction of tiles and of length 75mmat wall ends/ corners fixed on top of the vertical sections at spacing of 250/ 300/ 400mm c/c matching to the tile horizontal grid with twonumbers of self-drilling / self-tapping SS screws of size 5.5x25 mm with EPDM washers. The vertical 'T'/'L/ Tubular' sections shall be fixed to the wall using HDG (hot-dip-galvanized) steel L-brackets (galvanizing thickness ofminimum 80 microns)of size 110x80x6 mm at intermediate vertical aluminium profiles and of size 220x110x12 mm at outer corners andstainless steel grade 304,M10 full threaded anchor fasteners with nylon sleeve 100mm long (for brick work) and M8 expansion anchorfasteners 75mm long for concrete surface, spacing of brackets to be based on a structural/ static calculation. The brackets shall be oflength 175mm at junction of two vertical aluminium profiles and of length 100mm at intermediate points of vertical profiles and shall befixed to the vertical aluminium T / L / Tubular profiles using two numbers self-drilling/ self-tapping SS screws of size 5.5x25mm with EPDM washers.
EPDM gaskets to be fixed in between brackets and vertical profiles. The tiles shall be mounted on the ‘C clamps such that the tiles aresupported at top and bottom at both ends. The tiles shall be additionally secured to the horizontal ‘C clamps using special SS clips ofrequired size which shall be inserted and pressed into position on the ‘C clamps holding the tiles and the cut-tiles shall be glued at pointsto the horizontal ‘C clamps by using MS Polymer sealant adhesive. The vertical joint open groove between two adjacent tiles shall be5mm. The tiles and system shall be designed to resist wind load as per IS 875 (Part 3) according to different zones. The tiles shall beinstalled using the ventilated rain screen principle with provision for natural ventilation of the space between the facade tiles and thestructural wall. The work shall be carried out as per specification, drawing and as per direction of the Engineer-in-Charge.
Note : Scaffolding wherever required to be paid separately.
