From the end of the school day on a Friday for 10 straight days, CMD operatives worked later shifts to ensure all work in the playground was completed for the children’s return after the half term holiday.
This included digging 35m3 for the new ASHP base, building a 1.4m high retaining wall and pouring an in-situ brushed finished reinforced concrete slab. CMD operatives also dug a 90m trench across the playground for the electric services to the mainframe, and a 30m trench for the mechanical pipework to the school building.
The trench work was dug and completed in 5 days, winding through existing services, breaking out hard concrete and hand digging beneath a canopy where the excavator could not reach. This was all backfilled and reinstated with two layers of asphalt, some paving slabs and an area reinstated with artificial grass.
The whole playground was swept and cleaned up ready on time for the children’s return on Monday morning, with only a return visit to install the new security fencing once the ASHP’s were placed.
Using steel palisade fence posts, both bolt down and dig in, the timber hit and miss, play-safe fence was erected over a weekend to ensure safety for the children playing around the mechanical kit. An additional, matching timber enclosure was build where the pipes were fixed to the wall, to ensure protection and continuity for the project.
