Concrete Frames

GCL has built a reputation as one of the premier concrete frame contractors in London and the South East of England. This has been achieved by: retaining a loyal and experienced workforce, investing in the latest formwork technologies, training, Health & Safety and delivering on time for our clients. 

recyclePrecast

By breaking down the construction process into it’s core elements, GCL can combine off-site prefabrication with on-site assembly. The use of pre-cast columns or walls results in improved progress between floors, a higher quality finished product and increased design flexibility.

zig zag Post-Tensioning

GCL recognise that alternative forms of construction can sometimes meet our client needs. Given the opportunity to review the project at an early stage we regularly substitute the traditional reinforced concrete solution with a post-tensioned (PT) or precast concrete option. GCL have extensive experience of using both bonded and un-bonded PT systems in beams, one-way and column supported two-way flat slabs particularly where spans are in excess of eight meters. If required GCL can assume the full design, procurement and construction responsibility for the PT elements.

Why consider PT:

  • Reductions in floor slab thickness – which deliver savings in materials but potentially the opportunity to increase the number of floors in high-rise buildings,
  • Fewer deliveries, lifting, & fixing on site than traditional RC,
  • Reduces the requirement for beams, thus simplifying the falsework process,
  • A greater contribution to BREAM ratings

craneSlip & Jump form

GCL ensures the safety of operatives, the safety of those below and progress on site by using various edge protection systems. On high-rise buildings, where there is an increased risk to the public or surrounding infrastructures , climbing edge protection can be designed and incorporated into our TW system. This system provides a fully enclosed screen around the floor being worked on and one or two floors below. As the climbing edge protection progresses up the frame, lower floors are made safe using Combi safe panels for the follow on trades.
