Roof Renewal Works at St Cadoc's Primary School and Woodfarm High School

Description

East Renfrewshire Council has a requirement for a suitably qualified and competent contractor to undertake roof renewal works at St Cadoc's Primary School and Woodfarm High School. The full details of the project including the specifications and drawings etc will be available with the tender documents. St. Cadoc’s Primary School: Description of Works. The primary school is to receive a new roof covering as noted in the contractor’s condition survey. We will undertake these works in the stages as recommended in the survey report. Phase 1 includes the roof over the main entrance, kitchen and dining area and classroom’s 17, 18, 19 & 20. The works will entail removing the existing dilapidated bitumen roof covering, removing the existing 40mm insulation and any water-proof membranes (repairing the existing sarking where necessary) The proposed installation is for a new vapour control layer, 140mm of new rigid insulation to achieve a U-Value of 1.5W/m2K topped with a new two-layer bitumen roofing system. As we are raising the thickness of the roof, we will need to raise certain areas including parapets and window openings with external quality timber to accommodate the 140mm insulation. As a result, the clerestory windows we are replacing will be smaller than the existing windows. We have conducted a survey of the rooflights and roof penetrations and can remove 3 of the existing rooflights and we will replace 8 others and all existing vents will be re-sealed. Any internal finishes affected by the works will be made good to match existing. Woodfarm High School: Description of Works. The roof of the existing games hall will be stripped of the existing bitumen roof covering, insulation and membranes. The existing deck will be inspected for damage and repaired as necessary. If the existing sarking is good, we will install a new vapour control layer and 140mm rigid insulation board to achieve 1.5W/m2K and then the new two layer bitumen roof system. The new system will be dressed up the full heigh of the parapet and will be capped by a new aluminium capping system. The existing roof drains to valley gutters along the long elevations. The drains are to be inspected and cleared if necessary. The existing rooflights have long since been covered over internally so we will remove them and cover over with the new finish including any additional works required to fill in the aperture in the deck. Any internal finishes affected by the works will be made good to match existing.
