Working for Galliford Try, Careys are delivering a number of key packages on this large-scale scheme. With an anticipated programme of 42 weeks and a team of approximately 65 on site, the scope of work includes:

  • Substructure concrete works comprising pile caps and pad foundations
  • Process equipment RC pits and plinths
  • Ground floor industrial floor slab and upper composite slabs
  • External civils works including roads construction (excluding tarmac works), service yard RC slabs, external foul and surface water drainage networks

The scope also includes construction of a 7m deep circular cofferdam at 19m diameter to allow the excavation and construction of the Vertical Layup Machine (VLM) pilecap and embedded support ring; the VLM is used for manufacturing the subsea cables.

Once cast, the cofferdam is being sacrificed, cut to level and a circular retaining wall cast. Careys is undertaking temporary works design responsibility for the cofferdam and temporary steel support structure (which supports the large cast-in HD ring), in addition to bespoke formwork design.

The team face the typical challenges relating to design information, which is driven by the process equipment selection. Any impact is being negated through steering the programme and working collaboratively with the Galliford Try team and design team to focus on key information and release dates. Close coordination with other key supply chain partners, specifically around the steel erection, roofing and cladding is also paramount to maximise efficiency and reduce programme risk.
