Construction of Multi Sports Artificial Turf Facility at TISS Mumbai Campus

Cleaning the existing surface thoroughly by removing all dust, dirt, debris, oil, and loose mortar. Rectifying minor unevenness or joint grout failures using high-strength polymer-modified cementitious mortar to ensure a completely uniform, level, and clean surface ready to receive synthetic turf adhesive, including all labour, materials, and disposal of waste, etc., complete as per the direction of the Engineer-in-Charge.

Supplying and laying premium closed-cell Polyethylene (XPE/PE) or Polyurethane elastic shock-absorbing pad of thickness 10mm to 12mm, specialized for outdoor sports arenas, laid over the prepared surface, joints securely bonded with specialized outdoor single-component polyurethane adhesive tape, to achieve proper force reduction and performance criteria as per international sports standards, complete as per manufacturer specifications.

Supplying, jointing, and fixing of UV-stabilized, non-directional, heavy-duty Monofilament/Fibrillated synthetic artificial grass turf of 30mm to 50mm pile height (as specified), minimum gauge 5/8 inch, with a rugged double-layer polypropylene backing coated with polyurethane/latex finish. The turf rolls shall be jointed using high-tensile Geotextile Joint Tape (minimum 200mm width) and specialized two-part polyurethane outdoor grade adhesive (e.g., Speb 7 or equivalent). Item includes neat line marking in white/yellow synthetic turf rolls for football boundaries, all labour, tools, and tackles complete.

Providing and infilling dry, washed, oven-dried, rounded/sub-rounded silica sand (grain size 0.5mm to 1.0mm), free from dust, clay, and organic impurities, evenly spread over the installed artificial turf at a uniform rate of 12 kg to 15 kg per Sqm (or as per manufacturer specification for the chosen pile height) using a mechanical spreader/brusher to ensure pile stability and verticality, complete.

Supplying and installing high-density, multi-sport UV-stabilized artificial turf of 15mm pile height, dense texturized curly monofilament yarn (Dark Green/Bi-colour), specifically designed for cricket pitches of size 20m × 3m, laid over the prepared base, thoroughly bonded using outdoor grade polyurethane adhesive and seam tape, including permanent white turf line markings for bowling and batting creases, complete.

Steel work in built up tubular (round, square or rectangular hollow tube etc.) trusses etc., including cutting, hoisting, fixing in position and applying a priming coat of approved steel primer, including welding and bolted with special shaped washers etc. complete.

Providing and fixing MS base plates (minimum 300mm × 300mm × 10mm thickness) welded to the base of vertical posts, secured firmly onto the existing concrete/stone base using high-tensile mechanical/chemical anchor fasteners (minimum 4 nos. of M16/M20 bolts per post) drilled to a minimum depth of 150mm, including grouting the voids with non-shrink high-strength epoxy grout, complete as per Engineer In charge.

Supplying and fixing heavy-duty, UV-stabilized, weather-proof, braided High-Density Polyethylene (HDPE) / Polypropylene sports netting (Garware or equivalent make). Side Netting: 40mm to 50mm mesh size, minimum 1.5mm to 2.5mm twine thickness. Roof Netting: 50mm mesh size, 2.5mm twine thickness. Netting to be hung securely using 4mm/6mm PVC-coated GI wire ropes, stainless steel D-shackles, and turnbuckles, interlaced tight to prevent sag, complete.

Providing and fixing 2-meter-high safety impact protection padding around all internal vertical MS posts, goalposts, and gate frames within the playing area. Padding shall consist of minimum 25mm to 50mm thick high-density EPE/XPE foam, wrapped in waterproof, heavy-duty, UV-resistant PVC tarpaulin fabric, securely fastened using an industrial-grade 3-layer Velcro/zipper strapping system, complete.
