Systems comprise 80mm expanded polystyrene insulation, mechanically fixed, base coats with glass fibre reinforced mesh, mechanical fixings, stainless steel trim and PVC edgings unless otherwise detailed. Costs in use include allowances for inspections, cleaning, sealant replacement, minor repairs and a major refurbishment in year 30. Costs vary with the size of the project, extent and complexity of detailing, access and finish selected. Costs are generally lower for larger projects. Costs are indicative and represent the average of a range. A cost analysis based on project specific information is essential for a realistic best value appraisal. The LCC values are sensitive to the assumptions made about maintenance. BLP Insurance provides latent defect warranties for buildings www.blpinsurance.com
