Perseid Upper School roof works

Description

Works comprise the strip up and renewal of roof system to isolated flat roofs at Perseid Upper School, Morden. The current sedum and single ply flat roofs have failed with various signs of patch repairs and poor detailing present. The Contractor will be expected to closely liaise with the site Caretaker in good time prior to works commencing and on a regular basis once on-site. Works are in response to water ingress issues despite patch works being undertaken. Works will involve stripping the existing sedum roof and single ply membrane including circa 200mm of insulation to expose the deck. Subject to inspection of the deck it is assumed that new VCL can be installed before insulation and application of a high performance liquid overlay system incorporating PIR insulation to meet Part L2B of Building regulations. A manufacturers specification and drawings have been included although Contractors can quote for alternatives providing they are equal and approved. Works are to be undertaken over the summer holidays when there will be no children or activities on-site. As such there is no need for operatives to have DBS Certificates. Please note all correspondence, queries and tender submissions must be done via the London Tenders Portal.
