Design, Installation and Commissioning of Solar PV on Student Residence Roofs

Description

The University of Chichester is looking to appoint a competent contractor to design, install and commission solar PV on three of its Halls of Residences at its Bishop Otter Campus in Chichester. The three halls are all planned to be re-roofed, starting in September 2025. This work is urgent due to ongoing roof leaks. Whilst being pursued as quickly as possible, the necessary change in roofing material requires formal planning consent. The change in material is needed because the pitch of the roof is too shallow for the synthetic slates currently fitted. The new roof is planned to be Kingspan KS1000RW profiled insulated composite panels. These comprise a XL Forte plastisol steel outer sheet, a 40mm thick rigid quadcore insulation core and a bright white plastisol finish lining panel face. The University is currently progressing the planning application with the support of a planning consultant and a roofing contractor already "on board". As part of the project the University also wishes to install solar PV to reduce its carbon footprint and help reduce energy costs. Preliminary assessments in relation to solar PV have determined that solar PV is viable. A case has also been made for completing the re-roof and solar PV installations together, due to the saving on scaffolding costs. The planning application for the replacement of the roof therefore includes for solar PV too. Discussion in relation to procurement has however concluded that the design, installation and commissioning of the solar PV should be a separate procurement to the roof - although the University is seeking to see this co-ordinated with the new roof installation as efficiently as possible. As a consequence, this contract will be a design and build contract for the design, installation and commissioning of solar PV on the roofs of Amberley, Chilgrove and Harting student residences. The form of contract will be a largely unamended JCT Design and Build Contract 2024 (DB 2024). This will be kept separate from the roofing contract, but sectional completion clauses will be used to correspond with the planned phasing of the roof replacement works.
