This comprises regular site visits to establish and ensure the building contractor is constructing the project in accordance with the approved documents. Sometimes, building contractors will use materials not specified as they may be on offer at the builders merchants or simply because of the cost differences. Some materials that do similar jobs are cheaper than others which is often to the detriment of the design. It may be to your advantage to have someone indipendent on your side that knows just as much as the contractor. Knowing what things typically cost and identifying where cost savings have been made by the contractor and not passed on to you the customer could save you thousands of pounds. If you completely trust your building contractor 100% to look after your budget and build to the drawings then you will not need our services.
