An ECI contract requiring delivery of the scheme through publication of draft orders, public inquiry, publication of orders, and detailed design and construction.

A Public Inquiry (PI) was held in July 2009 over a four week period. No objections were maintained by any of the statutory bodies. This was achieved by closely working with the relevant bodies throughout the development of the scheme.

Following the successful PI, we were awarded the design and build contract and was completed ahead of time in December 2011.
