Housing Stock Profile

The properties in all the areas in appear to be constructed in approximately late 1960 - early 1970’s with a traditional cavity wall built in. While this information is correct to the best of our records, as a minimum a survey of each architype should be carried out prior to works starting to ensure full details are assessed and understood. These properties have been constructed with RAAC planks over the entire roof of the properties or on a section of flat roof with the remainder of the roof being mono pitch. A number of properties in Bathgate have RAAC Panels over the entrance porch and a further number have RAAC forming the roof of the integrated garage

As a minimum Asbestos Surveys will be provided for each of the property architypes, the Contractor will be responsible for removal & disposal any asbestos that may be disturbed or affected by the work.
