The City of Lake Worth Beach contracted with WGI to provide Survey and Subsurface Utility Engineering (SUE) services to support the design efforts on a proposed underground 138kV circuit from the existing Hypoluxo Substation to its Main Substation being approximately 16,000 linear feet. The entire route lies within public right-of-way being mostly I-95. WGI utilized in-house technology to quickly and safely collect survey data within hours instead of weeks. Due to the project being within the right-of-way and travelled lanes, the use of mobile LiDAR was implemented to increase safety without delaying schedule. Survey crews set mobile targets and digitally leveled through each point to provide the highest accuracy for the data collected. The mobile scans were registered to the control and checked against cross-sections and other ground truthing that was acquired. Over 80 manhole inverts were measured with some requiring special safety factors due to their locations. Flagman and electronic sign boards were utilized to access manholes located in the centerline of heavily traveled two lane roadways. Surveys from adjacent projects, such as the Florida Department of Transportation miscellaneous projects, the City’s District One Neighborhood Streets Improvements, and the City’s Pinecrest Cemetery survey were utilized as coordinated with the client to provide right-of-way and parcel lines. The right-of-way lines were used to show the relationship to the existing features as well to show the limits to the engineer of record. WGI’s SUE department proved to be reliable when called upon to track down an old electrical line no longer operational. The line generally followed the right-of-way line until it was mapped into the CSX railroad right-of-way where crews ceased activity and followed up at a later date once authorization was given and proper roadway worker protection was in place. WGI’s Utility Coordination department also prepared exhibits and collected records from 13 Utility Agency Owners which was later added to the final drawings and Pipe Networks file. The final deliverables were delivered one month ahead of schedule and without comments to be used by the City’s electrical engineer consultant.
