DDC offer a comprehensive range of Pre-design survey services. Pre-design surveys are a vital element in the development phase of a project. The goal of the survey is to identify all existing layouts and design prior to any construction works starting. This assists in understanding any areas that require remediation or any implications that could arise from proposed works. DDC typically carry out a Full Detailed Defect Survey to grasp and analyse the full extent of the design. The survey outcomes are presented accurately in a drawing format to assist the designers to undertake the designing work.
