Tender description

Glasgow City Council invites tender bids for the supply and delivery of safety surfaces for play areas and games courts. The tender has been allocated into 2 separate lots and they are as follows: Lot 1: Sand Filled Carpet; Lot 2: In-Situ Wet Pour Rubber. Lot 1: Sand Filled Carpet: Upper wearing layer: The upper carpet layer specification is applicable to the 2 installation scenarios: 1) New installations/refurbishments. For carpet refurbishments the existing shock pad shall be retained where possible. Supplier’s representative shall check and certify CFH of any alternative shock pad type proposed; 2) Minor repairs. For the sand filled synthetic carpet product supply of sand is not part of this tender however the system proposed must have been designed and tested with correctly specified sand incorporated into the synthetic grass surface. The supplier must detail the weight of sand (in kg) required per m2. Upper wearing layer: Material: Fibre type: 110(75 %)/18(25 %) Denier UVF multi directional fibre polypropylene(or polypropylene equivalent), manufactured for use with sand infill. Pile height: 11-15 mm ± 10 % Total thickness: 15-19 mm ± 10 % Pile weight: 1 200 g/m2 ± 10 % Total weight: 1 400 g/m2 ± 10 % Backing min.: 4 mm — needle punched SBR resin impregnated synthetic rubber or equivalent. Sub-surface shock pad layer: This can be more than 1 layer but shall be only one type of material for any fall height. Dimensions: Carpet sizes to be available in either 2 m or 4 m widths pre-cut to lengths appropriate for the intended site installation. Colours: The following minimum palette of colours must be available: red, blue, yellow, brown and green. Sub-surface shock pad layer: This can be more than 1 layer but shall be only one type of material for any fall height and should comply with below. A. New installations and refurbishments: — handling: weight and size of individual units to be easily managed by one person, — re-cycled content: while being desirable it should not reduce the longevity of the system, — future re-use: the material/tile used should be capable of re-use if a play area is refurbished or removed. B. Minor repairs: Where less than an edge to edge replacement/repair is to be carried out suppliers representative will advise on site build up required to match the original CFH and any further works, excavation or infill, required. Advice may be by email or by site visit if requested by GCC. Supplier will certify that CFH to match or exceed the original has been achieved. Recycled materials: If recycled materials are proposed for any part of the system then the source of the material must be detailed. Lot 2 In-Situ Wet Pour Rubber: Upper wearing layer: Shall be 1-4 mm ± 10 % EPDM (ethylene propylene diene monomer) granules either black or coloured as requested and composed of either new or recycled materials. Coloured granules must be fully pigmented i.e. not coated black granules. Clear polyurethane resin (PU) binder will be supplied to mix with EPDM granules. If recycled materials are proposed then the source of the material must be detailed (Note that BS EN 1177 ignition resistance test results are required.) Sub-surface shock pad layer: Shall be 2-6 mm ± 10 % SBR (styrene butadiene rubber) granules coloured as available. Clear polyurethane resin (PU) binder will be supplied to mix with SBR base granules. Granules can be new or recycled.
