Earls Gate Energy Centre
The Earls Gate Energy Centre is a new energy recovery facility at Earls Gate Park, Grangemouth. The new plant will replace an existing gas-fired facility and will provide heat and power for CalaChem and adjacent industrial plants, and export surplus electricity to the National Grid. The heat and power off-take will make the Earls Gate plant one of the most efficient in the UK, helping to drive the shift from fossil fuels to heat and electricity from renewable sources.
The Earls Gate Energy Centre's site situates on a depth of around 35 metres of soft Bothkennar Clay, posing problems for the construction of a deep bunker excavation on site. ByrneLooby picked up the project after initial construction activities ran into difficulties and developed the scheme to a successful temporary excavation where permanent works construction could commence. This involved specifying a monitoring regime and continuously adapting and tailoring the scheme to the feedback from the on-site monitoring. The analytical model was also refined during construction to reflect site observations and allow decisions to be made regarding the construction sequence. The approach resulted in finding a construction sequence methodology which allowed the contractor to expedite the excavation of the bunker.
