Fowey River Academy
Everyone has mentioned that it was a great visit, with the whole party impressed with the ease of access and efforts to accommodate them on site. All were impressed with the size of the building on the site and how little it was impacting the wider area. One or two were impressed that works were ongoing whilst the visit was in progress, noting that often that site visits are often used by contractors as an excuse for a protracted work break!
Newlyn Harbour

Cornwall Partnership NHS Foundation Trust
We have found it helpful that the site team have approached any challenges in a positive and pro-active manor working to resolve any emerging problems in a constructive and collaborative manor. Attention to detailing, specifically fire stopping which we understand is a business specialism has been noticed to be high quality.

Tower block and Science labs are finished to very high standard and the teachers can’t wait to get back in them. So pleased to final use the space for learning after so long of being derelict.
