As-Built Surveys

The collection of post-construction, as-built data is critical for general maintenance and in planning for future expansion. Certified Engineering has performed hundreds of as-built surveys for developers, pipeline companies, municipalities, telecommunication companies and government agencies to document the location of their improvements. From finished floors, water lines, and storm or sanitary sewers, to natural gas or petroleum pipelines, to television or cell phone towers, we are ready to gather the data you need.
