The $834 million Northwest Corridor is an 11-mile corridor of I-75 and 1.5-mile section of I-575. The database was used in design of the widening of both Interstates to provide two congestion priced High-Occupancy Vehicle (HOV) lanes along I-75 and 1 congestion priced HOV lanes along I-575. Services included static and RTK GPS networks and right-of-way resolution. LONG utilized eight survey field crews and three Registered Land Surveyors simultaneously on the project to maintain the aggressive schedule.

LONG provided surveying services associated with the widening and bridge replacement on the road from Johnny Mercer Boulevard to Old US 80 on Tybee Island. All topographic surveys extended 200+ feet left and right of the edge of the marsh, rivers, and streams. The topography defined the terrain beneath the bridge to include end rolls, stream banks, and other breaks in elevation. This included Bird Island which is approximately 238 acres at high tide and 871 acres at low tide and is only accessible by boat. LONG utilized echo sounding technology for their surveys on this project which is a type of sonar used to determine the depth of water by transmitting sound pulses into water.

The SR 400 Express Lanes is one of the Major Mobility Investment Program (MMIP) projects to improve mobility along SR 400 (GA 400) in metro Atlanta, one of the most heavily-traveled and congested interstate highways in the state. The GA 400 section focuses on adding two new at-grade and elevated, barrier-separated express lanes in both directions of GA 400 from the North Springs MARTA Station in Fulton County to McFarland Rd in Forsyth County.
Long Engineering (LONG) provided SUE and UC services for the 20-mile project that began just south of Spalding Drive and continued north of McFarland Parkway. It included 15 roadway crossings where the majority of utilities exist. Scope items included Quality Level B (QLB – designating and marking all underground utilities), pole data, sanitary sewer identification, and UC for 15 utility owners. 400k feet of utilities were designated (QLB), 700 utility poles were classified and included in a pole data table, and 200 sanitary sewer manholes had inverts and connectivity identified. The final deliverable included a Memorandum of Understandings (MOU) and Utility Analysis (UA), along with a Utility Matrix showing utilities in conflict with potential costs.
LONG’s scope also included subcontracting and managing the inspection of all storm drainage pipes along the corridor. The inspection was performed using a CCTV robot crawler to inspect 319 manholes, 869 inlets, and 107,000 feet of 18” -48” inch diameter pipe.
