Heathrow Terminal 3 Service Subway – LTHW Pipework Upgrades

RK Air returned to the Terminal 3 Services Tunnels to complete upgrades to the LTHW pipework system.

The purpose of this installation was to replace existing pipework that was identified as being in poor condition following NDT testing, with new 100mm,150mm, 200mm pipework complete with associated isolation, flushing, drain and venting valves and test points.

We also showcased our civils capabilities, removing any existing damaged concrete in the walls of the tunnel and completing repairs.

The project was successfully completed under the pressure of challenging conditions, including onfined spaces – and all within a tight programme. It saw our RK Air teams strip out the old and install the new pipework over the summer shutdown period.
