The land surveyors at CNA have extensive experience in creating as-built maps and design survey drawings to convey the positions and elevations of the existing permanent site features on the ground. This includes but is not limited to: buildings, walls, structures, utilities, light poles, manholes, fences, ground surfaces and grading. Based upon a project’s specifications, these maps are used as the foundation for engineering and architectural design projects and formal plan design purposes.
An as-built survey shows the actual horizontal and vertical locations of features in a completed structure or project. As-built surveys can be performed for a variety of projects including interim design and shop drawings for governmental submittals.
CNA has performed thousands of surveys for design professionals within the public and private sectors and has vast knowledge of the requirements necessary to complete design surveys. We deploy the proper equipment and techniques to perform accurate mapping to each project’s specifications.
