We were responsible for providing boundary, topographic, utility, and bridge surveys for the redesign of the Ambassador Gateway.
This project required extensive surveys, thus we were responsible for property research, easement preparation, and establishing project boundaries and the necessary exhibits for the acquisition of properties by MDOT within the project scope.
Surveys we created were used for the rehabilitation of Fort Street from Rosa Parks Boulevard to Clark Street; the rehabilitation of West Grand Boulevard bridges over I-75 connecting to Fort Street; I-96/I-75 freeway reconstruction from the railroad bridge northeast to I-75 and northwest to I-96; construction of ramps leading I-96 and I-75 mainline freeways directly to the Ambassador Bridge; and the design of the Bagley Avenue pedestrian bridge.
We were responsible for providing topographic as well as an extensive subsurface utility survey for the approximately 55 acre portion of Downtown Detroit known as Campus Martius for infrastructure redesign as well as future development.ht
In addition we established right-of-way locations for 14 blocks within Campus Martius, prepared Condominium Documents for the “New” Kennedy Square, and provided easement documents for the preservation of existing utilities and for future installations.
Throughout the project, we used 3D laser scanning for the topographic as well as for historic documentation of the existing conditions. Our team was also responsible for the re-establishment of the Point of Origin for the City of Detroit.
We prepared topographic and ALTA / ACSM land title surveys of the Greektown blocks in downtown Detroit.
Greektown is a famous location of Greek influenced shops, eateries, and most recently, the Greektown Casino. Our surveyors prepared legal descriptions for the transfer of land to create composite legal descriptions of the total area. We used laser scanning to obtain the topographic information for preparing the survey that was used in the Greektown Casino Construction and the Streetscape Rehabilitation project.
Our company’s role was to provide the Design Team with a survey demonstrating the existing site conditions. Primary and Secondary Control Networks, aerial and conventional topographic mapping, boundary establishment and geotechnical support were all provided.
Over 300 easement documents were then created along the alignment granting DWSD subsurface drainage rights as well as construction and permanent easements at the existing outfalls and lateral alignments.
The project consisted of an overall base map for a 48 mile topographic survey, aerial photo control survey, and right-of-way survey for the design of a water transmission line through eight townships and two counties for the Detroit Water and Sewerage Department.
Over 200 horizontal control points and 285 benchmarks were established along the route of the project. Over 348 aerial control points were measured for the 30 flight lines needed to obtain aerial data.Read more link
Mapping information included a conventional topographic survey of all hard surfaces and utilities. Mapping also included all pertinent features, comparison measurements for aerial data, right-of-way determination data, and a digital terrain model along the route of the project.
Right-of-way surveys were performed along the route of the proposed water main. The scope of the project included property research and ownership investigation for 1400 parcels.
For this project, we were contracted to perform a complete topographic design survey for the first phase of the M-1 Light Rail project covering over 3.4 miles of Woodward Avenue from Jefferson Avenue to West Grand Boulevard.
A combination of 3D laser scanning and conventional survey methods was used. Topographic features found within the project limits were collected in the office by our HDS Technicians from the point clouds.Read more link
Our team of experts also inventoried utilities from the point cloud and verified the data via field check. Some of the features located from the scan data were curb, gutter, edge of metal, lane lines, centerline of road, overhead utilities, storm, sanitary, telephone, cable, buildings, overhangs and water services.
Great Lake Geomatics team laser scanned a complex assembly of overhead transmission lines for DTE Energy in Detroit. The resulting digital database allowed DTE to easily determine elevation and sag of the lines, among other things, without physically returning to the site. The measurements were used to support a facility reconfiguration project.
Steam manhole pits covering a large portion of the facility were to be scanned, but the effort was complicated by the Lab’s strict ‘No Confined Space Entry’ policy.By inverting the scanner and lowering it into each of the structures, we were able to obtain full scan coverage and meet all requirements.
We were contracted by the Detroit Water and Sewerage Department to survey a large potable water pumping station.
Laser scanning technology was used to create a spatially accurate and complete 3D model of the facility.
The ancient Maya city of Chichén Itzá was recently inducted as one of the New 7 Wonders of the World. In 2007 our team, in association with CyArk, created a complete digital database of El Caracol, one of the oldest standing observatories in the Americas.
The project also involved laser scanning of other important structures at the site, including El Castillo, the Temple of Warriors, Osario, the Grand Ball Court, the Venus Platform, and the Nunnery. GLG laser scans from Chichén Itza are currently featured in a full-dome planetarium movie “Tales of the Maya Skies” at the Chabot Space & Science Center in San Francisco.
