For our modeling tasks, GdB also created custom parametric families for items not provided by the manufacture or the client to properly model all features. Based on conversations and specifications from the client, Building Information Modeling for this task was prepared to Level of Development (LOD) greater than 200, but less than LOD 300.

HVDC Poseidon Transmission Cable Project
This was GdB’s largest ground control effort for Aerial Imagery to date. Field Crews set aerial targets at specified distances and provided survey accurate coordinates for photogrammetrists to perform their work to accuracy standards. GdB prepared and provided a complete survey file in AutoCAD Civil 3D utilizing pipe networks and progress was constantly tracked in GIS. This huge survey and mapping effort was expedited and completed within only six months, on time and within budget.
Amtrak Bridge Replacement over Pawcatuck River
For the site, GdB conducted due dilligence boundary research, obtaining records from publicly available municipal agencies and Amtrak. GdB field crews completed a Quality Level “C” utility survey, compiling record plan data with located surface hardware. This mapping was included in the basemapping deliverables to the client.
MTA LIRR – 3rd Track Design Build
GdB provided over 10 miles of right-of-way survey between Floral Park and Hicksville to determine the boundary between the MTA LIRR and the adjoining private ownership. Since the LIRR ROW was established in 1837, the determination of boundary locations over 182 years of development was an incredible effort by GdB. Record research from various towns and municipalities was performed to obtain relevant filed maps, deeds or property surveys for properties adjacent to the project scope area.
