161 Maiden Lane – 58 Story Wall Scan

Manhattan, NY

Gayron de Bruin Land Surveying and Engineering, PC performed 3D Laser Scanning services of a 58-story building under construction at 161 Maiden Lane, New York, NY.

Four independent control networks were set, each relating to a different side of the building to determine if the building was leaning. Independent scans were performed on the full extent of the building in question on rooftops where the building was visible as well as from the streets in the immediate vicinity. GdB utilized a Leica P50 3D Laser Scanner to perform this detailed work.

Deliverables included the registered point cloud and an AutoCAD 3D file containing polylines representing the perimeter of each of the 58 floor slabs. The CAD file also included offset dimensions on all faces of each floor.

This project was delivered on time and within budget.

Honk Falls Dam

Napanoch, NY

At the Honk Falls Dam in Napanoch, NY, GdB provided comprehensive field surveys, topographic and utility mapping for future design efforts. GdB used a combination of traditional survey methods as well as Aerial Drone Photography and Baythmetric surveys to complete this task.

Carrel Boulevard Drainage Improvements

Oceanside, NY

Gayron de Bruin Land Surveying and Engineering, PC was hired as a subconsultant to perform surveying and mapping services to Town of Hempstead specifications which included topographic, boundary and subsurface utility mapping as well as storm water and sanitary structure investigations within the specified project scope.

Following Town of Hempstead surveying and mapping standards, elevations were taken at 25’ cross sections for roughly 4,675 linear feet of roadway. All planimetric features and topography was mapped up to the face of the houses, which included house corners, first floor elevations, garage floors, top and bottom of entry way steps, window wells and planting areas as well as any and all features that may be impacted by regrading and raising the road. GdB used a combination of traditional ground survey and terrestrial LiDAR to optimize our time spent on this task.
