Construction Survey

This type of survey requires staking out structures located on the property, including walls, buildings, roads, and utilities. Staking provides construction personnel with directions for implementing the improvements shown on the development plans. A construction survey may also involve both horizontal and vertical grading in addition to an As-Built survey. The results of construction surveying are seen in almost any urban, suburban, and even rural setting. Almost any roadway, building, or other man-made improvement probably had some amount of construction surveying involved. Construction surveying provides not only the horizontal location of new improvements, but also the vertical information required to ensure that surfaces drain or pipes flow as required.

Elements of the construction survey:

  • Survey existing conditions of the future work site, including topography, existing buildings and infrastructure, and underground infrastructure whenever possible (for example, measuring invert elevations and diameters of sewers at manholes)
  • Stake out lot corners, stake limit of work and stake location of construction trailer (clear of all excavation and construction)
  • Stake out reference points and markers that will guide the construction of new structures
  • Verify the location of structures during construction
  • Provide horizontal control on multiple floors
  • Conduct an As-Built survey: a survey conducted at the end of the construction project to verify that the work authorized was completed to the specifications set on plans
  • Strain monitoring

All types of geodetic surveys are performed in accordance with the Building Regulatory Requirements and Documentation.
