The client was seeking a contractor to lead the installation of a major services infrastructure package to the development of a 660 acre redundant airfield into a major research and technology park in Wiltshire.
Tercon were awarded the contract under an ICC Infrastructure Conditions contract form to design and deliver the infrastructure in a civils led arrangement.
As parts of the site were already live and under high security arrangements, with other site areas occupied by live construction projects, extensive coordination and planning was required with all stakeholders at every stage.
Client changes needed to be managed through the supply chain of services specialists with close control of interfaces at each stage and careful monitoring of costs.
