FEGP Works, London City Airport

London City Airport wanted to realign its aircraft stands, and that meant moving the Fixed Electrical Ground Power (FEGP) infrastructure that feeds them. TAG was contracted through Tarmac to reposition six new FEGP chambers and connect them back into the existing network on the main apron.

The constraint was operational continuity: the work closed only two stands at a time, while the remaining eight stayed live. TAG precast all six new electrical chambers off site before bringing them in, then saw cut and excavated the PQC and DLC bays across four stands to install the new ducting.

Once the chambers were in, the team installed new two-way electrical ducting linking old chambers to new, laid 25 metres of 100mm drainage pipe back to the existing carrier drain, reinstated the wetlean concrete base, and rebuilt 19 PQ concrete bays in high early strength concrete to get the surface trafficable again fast.

The £125,000 scheme, delivered between July and September 2014, gave London City Airport the realigned power infrastructure it needed without taking the whole apron out of service to get there.
