Capability 03 · Civils & groundworks

Civils that let the wiring team start on day one.

Piled foundations, access roads, troughing routes and enabling works. Self-delivered and sequenced to the electrification schedule, so OLE and HV teams arrive to a site that is ready to build on.

Cable troughing routes (concrete and GRP)
Drainage, fencing, security
Compound set-up, welfare, site infrastructure
Permanent way interface works
Demolition and site clearance
Environmental mitigation and ecology management

Why self-deliver

Civils failures are the leading cause of OLE slippage.

A foundation that fails a CP-test. An access road that washes out. A troughing run that arrives three weeks late. Each can cost a possession, and possessions cannot be recovered. We self-deliver civils so the schedule has one owner, the risk register has one format, and the commissioning engineer does not arrive to find a foundation that is not their problem to solve.

Possession-aware

Design philosophy

I. Early contractor involvement

The possession risk of the whole scheme is set at GRIP 2.

Where clients allow it, we engage at GRIP 2 to influence foundation strategy and access planning. The decisions made at this stage set the possession risk for the whole scheme.

II. Ground investigation & design

Foundations designed for the possession window that will install them.

In-house geotechnical interpretation and foundation design. We design foundations that can be installed inside the possession windows the OLE programme assumes.

III. Install

Own plant. Own crews. Known location next Tuesday.

Our own piling rigs, excavators, concrete pumps and rail-mounted plant. Self-delivered means we know where the rig will be next Tuesday, because it is ours.
