CGA provides complete construction layout services for residential and commercial development projects, as well as IDOT construction. With state-of-the-art technology, 12 survey crews, and the numerous years’ experience of our team, your construction project couldn’t be in better hands!
What is construction staking?
Construction Staking is the process of interpreting an engineer’s or architect’s design drawings and locating the proposed improvements on the ground with stakes for contractors to use for construction. This is a very important step in the construction process. Surveyors typically lay-out buildings, walls, roads, utilities and any other proposed structure whose location or elevation is critical. CGA provides complete construction layout services for residential and commercial development projects, as well as IDOT construction.
Once designs are completed, it is important to be able to accurately and concisely communicate necessary information to the Contractors. This is done through a combination of information on the plans and stakes in the field. Our team is experienced in analyzing field conditions to set stakes and control in locations that are useful and out of the way for the Contractors.
Keep your Project
The CGA survey department adjusts the number of survey crews depending on work backlog. Our forecast of work allows us to adjust in advance and plan for design survey in our operations. Survey personnel will be made available as needed for this project to keep the project on schedule.
While all Contractors complete a self-check-out of their constructed stormwater management facilities, our office performs spot checks to ensure compliance with proposed elevations and grades.

Definitions of Project
A Site Plan is a pre-construction survey that shows the location of the proposed building, parking or driveway, and other improvements. It is composed of a Boundary Survey, Topographical Survey, and a Grading and Utility Plan according to county requirements.

Vital to any construction project or land sale transaction is the accurate location and documentation of property boundaries developed by a professional land surveyor. Boundary Surveys are undertaken to determine the location of property lines and the actual physical extent of property ownership, typically witnessed by monuments or markers. They can also reveal potential problems including encroachments, right-of-way and easements, and gaps or overlaps between adjacent parcels. The surveyor performs courthouse research to obtain deeds and other vital information for the subject and adjoining properties which represent ownership, easements, and other interests. The surveyor then performs fieldwork to locate property monuments as called for on subdivision plats. A plat is then drawn from the data showing all property lines and dimensions. Property is valuable. Our experienced team prepares boundary surveys on tracts of all area sizes, in a timely manner, with quality results.
The successful planning and engineering of any land development rely on quality topographic data. A Topographic Survey determines the positions of natural & man-made features and configuration of the terrain on a particular piece of land. The elevations of the measured points are presented as a three-dimensional shape and represented as contours and spot elevations on a drawing. The finished drawing shows the location of all visible improvements such as roads, driveways, buildings, walls, fences, and sidewalks. The survey also shows any above or below ground evidence of utilities such as manholes, valves and fire hydrants. The scope can be broadened to include a more intensive Utility Survey.
Subdivision Platting is undertaken when an existing parcel is subdivided into smaller lots or multiple tracts and conversely when multiple parcels are combined into a larger tract. The process varies considerably with jurisdiction but often involves a multiple step process of reviews, hearings, and approvals by multiple governmental entities.
