GTS Provides Scanning Services

The Garden State Parkway (GSP) has undertaken a major improvement to Interchange 145 which connects the GSP with Route I-280. Working as a sub-consultant to the design team, GTS was responsible for all survey-associated task efforts. These activities included primary and secondary control network establishment, aerial/topographic mapping, roadway baseline re-establishment and detailed bridge survey mapping. Due to the complex existing conditions (tunnel type corridor, lack of full shoulder areas and high traffic volumes) GTS proposed the use of High Definition Survey – 3D Laser Scanning in order to capture the entire corridor including the overall bridge with minimal impacts to highway operation. GTS performed their scanning activities in two sessions. We performed the work at night using only one lane closure and collected data for the entire bridge substructure. GTS then extracted site data information as needed for the design team. The advantages of this comprehensive data capture provided significant value and cost savings to the Authority as well as the design team.
