Slow responses from plant vendors have impeded generic design assessments (GDA) of two nuclear reactor types vying for the U.K.’s potentially large “new build” program. In an interim report released on Nov. 7, the U.K. Health & Safety Executive (HSE) lists inadequate submissions in support of the Westinghouse AP1000 and Areva’s EPR reactors. “If we are to complete GDA on time, we need the design companies to work with us and provide the high-quality and timely information we need,” says Kevin Allars, HSE’s director of the assessment. HSE is scheduled to complete the GDAs in June 2011 after 42 months
The market is generally healthy and steadily growing, and margins are up for large specialty contractors. Further, advances in design tools and owner demand for collaboration are giving subcontractors a seat at the table early on in projects.
