New constructible projects typically begin with an Engineering Design Survey, requested by the civil engineer in charge of the project design. These surveys include ground level topography, and the location and documentation of visible evidence of existing improvements.

During the design survey, the Professional Land Surveyor works closely with the civil engineer to gather the “as-built” existing site conditions in and around the proposed project, and determine all of the controlling elements to be used as the basis for the project design.

They can be performed for a wide range of civil projects, including the design of roads and bridges, Drainage Basin Studies, Water Quality Improvements, Stormwater Improvement Projects, and Sanitary Sewer Retrofit Projects.

Engineering Design Surveys incorporate elements from land, hydrographic and geophysical surveys. Our surveyors can work closely with engineers and planners to develop survey drawings that will be incorporated into engineering design plans.

The purpose of an Engineering Design Survey is to ascertain a range of key elements, including:

  • condition of the adjacent streets
  • location of visible improvements and easements
  • field measurement of elevations (Topography, Cross Sections, Profiles)
  • sidewalk gradient (Is it ADA compatible? Is it in need of replacing?)
  • presence of driveway access areas from the streets to the site
  • evidence of electrical/gas/sewer/water utilities servicing the site
  • improvements and conditions around the perimeter of the site (Are there walls/fences that follow or cross over the property line?)
  • evidence of underground contamination, dumping or site access from an adjacent property
  • whether the site is buildable

This information along with site photos and public record documents gathered at the local agencies will form the basis for the engineering design and plans.
