AsBuiltsAs-Built and Engineering Documentation Projects

GLG uses conventional surveying methods and laser scanning to provide our clients with affordable, precise, and accurate as-built and engineering documentation services. We specialize in as-built surveys for multiple items.

  • Pre-cast Concrete, Steel, and Caissons
  • Storm, Sanitary, Water Main, and Utilities
  • Paving and Grading
  • Buildings and Bridges

GLG has been responsible for many as-built survey and engineering documentation projects throughout Michigan and other parts of the country using conventional survey methods and incorporated with laser scanning. As-built and engineering documentation projects GLG has been involved include MGM Casino, Detroit Water Works Park, JP Morgan Tier III Center, and Greektown Casino.


Greektown Casino

greektown-casinoWe performed the as-built survey, construction staking, boundary survey, ALTA surveys, and topographic survey throughout the course of this project. We were responsible for overseeing the layout and coordinate calculations of all caissons, columns, and pre-cast walls. Our crew was also responsible for the as-built survey of over 1,000 anchor bolts and all pre-cast concrete involved the projects.

We used laser scanning in the as-built survey process in order to check the level of the poured concrete floors throughout areas of interest of the new hotel. We were in charge of establishing high accuracy and precise horizontal and vertical control networks to be used by multiple trades during construction.
Project also consisted of the layout of all underground utilities and +/-1000 feet of integral curb and gutter.

JP Morgan Chase Tier III Center

jp-morgan-chaseGreat Lakes Geomatics was responsible for the engineering documentation for this project that consisted of the as-built survey of all newly constructed features.

We used conventional survey methods to compare as-built data with respect to designed features such as storm, water, sanitary, paving, and other miscellaneous features. We also used laser scanning to as-built and determine the volumes of newly constructed overflow ponds.

Detroit Water Works Park

detroit-water-works-parkWe were the prime surveyor for multiple trades over the seven year construction of this highly complex $285M project of Detroit Water Works Parks.The project consisted of establishing and maintaining a complex horizontal and vertical control networks used in the construction process.

Our responsibilities included construction staking, as-built survey, and inventory of over 1200 piles, site utilities, one mile of construction roads and new permanent roads, and formwork for multiple trades.

Both conventional survey methods and laser scanning were used in order to as-built underground features that were not shown on existing plans and needed to be incorporated in the design build process. We were the prime site surveyors used in the QA/QC of layout performed by multiple trades.
