Bowman provided dual mapping data as part of the flood warning and optimization system in addition to maintenance and inspection contracts statewide. The team was contracted to provide bank-to-bank bathymetric mapping and simultaneous LiDAR data collection of the Mohawk River between Locks E8 and E7 to support flood modeling activities.
Our team performed a multi-disciplinary mapping and sediment characterization study for Bergmann Associates. The project located at lock C/S-1 at the northern end of Cayuga Lake entailed performing multi-beam echosounding, single beam echosounding, aerial UAV topographic mapping, GPS survey, utility location and sediment sampling.
Partnered with Weeks Marine, our team provided multiple roles and services for this project. We acted as the geologist of record and provides construction material inspection and oversite services at the breakwater materials extraction source (Carver Johnstown Quarry).
Our team provided multibeam bathymetric scanning services to collect high density survey data below the water line on the Erie Canal in support of the Canal Corporation’s Navigation Information Program. Data was used to determine the nature of obstructions and detailed 3D images/maps of dredged areas.
Our team provided combined multibeam bathymetric and laser scanning services to simultaneously collect high density survey data above and below water line, in support of the Canal Corporation’s structural inspection program.
The City of Albany requested that our team perform updated bathymetric, LiDAR and conventional surveys of Alcove and Basic Reservoirs – two of the three reservoirs that provide the City of Albany with drinking water. The results of these surveys would also provide accurate volumetric estimates and capacity tables for these reservoirs.
Our marine engineers performed structural analysis of the bulkhead and designed the required rehabilitation of damaged sections of the dock bulkhead. Scope included performing repair design underwater inspection, developing conceptual alternates for the rehabilitation and developing estimated construction cost of each option.
Retained to conduct routine inspection of Philadelphia Energy Solution’s 3.5 miles of refinery waterfront along the Schuylkill River. The waterfront consisted of nine wharves, 22 steel sheet pile bulkhead sections (approximately 8,000 LF of bulkhead) and six categories of miscellaneous structures.
Bowman provided damage investigation, claim support, design, permitting, material procurement, and engineering support services during the construction of a approximately 104 FT span walking bridge to replace a pile bent supported walkway that was damaged by an aberrant barge at this petroleum facility.
The project involves construction of two mooring dolphins to tie up ships up to 750 ft long (LOA) and other associated construction work. Such construction work starts with the installation of falsework (temporary steel framing) to be able to install production piles at accurate locations and angles in the waterway.
