Project description
The set of equipment we agreed on is this. Three horizontal bars in one row at 2.1, 2.4 and 2.7 metres, so that a short person and a tall person both have their own. One pair of parallel dip bars at 1.35 metres, width between the rails 55 centimetres. A monkey bar ladder about 4 metres long at 2.5 metres height, with round rungs 32 millimetres in diameter spaced 40 centimetres apart. A low inclined bench for abdominal work and one wall bar section 2.4 metres high. Uprights from steel tube 89 millimetres with a wall of at least 3.5 millimetres, crossbars from 42 millimetre tube, gripping bars 32 millimetres, everything welded solid and ground smooth, no sharp edges and no bolts sticking out where somebody will catch a shin.
Footing and finishing matter to us as much as the welding. Uprights must be concreted below the frost line, that is at least 1.2 metres deep here, in a widened hole with crushed stone at the bottom and grade B22.5 concrete, and the tube ends sealed so water does not sit inside them over winter. All metal sandblasted or wire brushed, primed and painted with two coats of weather-resistant enamel, colours dark grey and yellow. Under and around the equipment we want rubber crumb, 30 millimetres over a compacted crushed stone base, with a safety zone of no less than 1.5 metres in every direction from each piece; if rubber crumb goes far over our budget, offer us a sand pit variant with a border and we will compare the two prices honestly.
Please quote materials and labour separately, tell us how many people will be on site and how many days the whole thing takes including the concrete curing period. We would like it finished within two weeks of the start. Concrete mixer and water are available in the yard, electricity from a house 20 metres away, so bring a decent extension. Show us photographs of two or three grounds you have already built and tell us what warranty you give on welds and on the coating.
