What are Civil Construction Surveys? Civil Constuction Surveys are used to plan, build, and maintain all civil engineering projects. A full survey of the target area is usually necessary to determine its exact boundaries and to ensure that any buildings or other structures constructed there will be safe. Surveyors also work to provide the proper design and development of infrastructure, to protect the surrounding natural environment, and to maximize the efficiency of the proposed structures.
