Storage Building in a Confined Area



London power tunnels

Hochtief-Murphy Joint Venture (HMJV) were contracted by National Grid to deliver the tunnelling and shaft work of the second phase of its London Power Tunnels (LPT2) project in a contract worth around £400m.
Fews Temporary Buildings were asked to build a workshop /storage structure in a confined area on the New Cross Worksite in Southwark, and another structure at the Hurst Worksite.

A 10 metre x 15 metre temporary building on a 6 metre leg was erected in a very confined space. A scissor lift had to be positioned on site using a crane to enable the structure to be built.

To insulate the structure, we fitted 40mm sandwich panel walls and a thermo roof.

3 x 4.8 metre x 4.5 metre steel roller shutter doors with electronic operation were fitted to provide vehicular access, and a single personnel door.

Proper drainage was required so steel gutters & downpipes were fitted all around the structure.
