Government
G&AI possesses a profound understanding of the unique dynamics within government markets. We have successfully provided survey services to federal, state, city, and county entities, gaining invaluable experience in meeting their specific needs. G&AI has conducted thousands of engineering design surveys, encompassing municipal projects, airports, street rehabilitation, proposed roadways, sanitary sewer rehabilitation, water rehabilitation, water and sewer transmission lines, gas pipelines, electrical transmission lines, and development projects. Furthermore, G&AI has executed surveys covering over 1,000,000 acres for boundary surveys, right-of-way acquisition, and platting services across 86 counties in Texas.
Tulsa Asset Inventory
G&AI acquired and processed 2,064 linear miles for an asset inventory within the City of Tulsa, OK city limits. The processed and classified point cloud and simultaneously collected 360° high-definition imagery were used to performed feature extraction of city assets including, streetlights, guardrails, MUTCD signs, traffic signals, traffic signal cabinets, and school zone flashers. All assets were collected and placed in a 3D ESRI geodatabase.

Randol Mill Rd.
G&AI established horizontal and vertical control for the project, performed supplemental ground surveys that include identifying obscured areas, size and types of trees 4 inches or larger, sewer/storm manholes, drainage structures, water valves, water meters, above ground franchise utility features and signs within the aerial data. G&AI acquired color digital aerial photography and aerial LiDAR from a UAS platform, conducted analytical aerial triangulation adjustment, and collect photogrammetric planimetric features. The Boundary to Support ROW/Easement Documents involved researching property Project Client s, obtaining copies of subdivision plats, Project Client ship deeds, and easements, and locating property corners, established property and right-of-way lines.
Intersection Improvements at S. Hulen Street at Oakmont Boulevard
G&AI provided a topographic/design survey for the Intersection Improvements at S. Hulen Street at Oakmont Boulevard. The survey included but was not limited to locating buildings, water valves, water vaults, top and toe of slopes, drainage ditches, fences, trees 6″ and larger, landscaped areas, miscellaneous concrete, electrical features, signs, utility markers, asphalt paving, concrete paving, curb and gutter, storm water and waste water manholes and drainage structures with flow lines and pipe sizes. G&AI also provided research on all adjacent properties to the project and obtained copies of all deeds, plats, and easements. As well as Prepare a deed sketch of the existing right-of-way and adjacent properties to the project site.

Denton Enterprise Airport Parallel Runway
G&AI provided professional land surveying services including topographic, aerial and mobile survey. The project included an aerial photogrammetric survey for the entire project area, totaling approximately 400 acres. This was supplemented with the collection of Mobile LiDAR data along the north-south runway (approximately 7,825′ in length) and along selected portions of the tarmac, as outlined on the project map.
14R 32K Taxiway Improvement
G&AI acquired mobile LiDAR data for airport taxiways on Randolph Airforce Base in San Antonio, TEXAS. 2D planimetrics and 3D DTM were extracted from the processed and classified mobile LiDAR data. The LiDAR data met TexasDOT specifications of 0.05-ft. vertical RMSE on hard surfaces. Deliverables included processed and classified LiDAR in .LAS format, georeferenced imagery in JPEG format, 2D planimetrics in AutoCAD format, 3D DTM in AutoCAD format, and TIN and DAT files in GeoPak format.
