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.
Retained to perform a thorough underwater inspection of Berths A and B to document the construction and evaluate the current condition of all existing dock structures and design the complete removal and renewal or rehabilitation of Dock A structures in a phased manner.
Designed, secured permits, and provided bid support and construction management services for the maintenance dredging of sites located on the Arthur Kill River along New Jersey and New York shorelines. Scope of work included pre-dredge surveys, calculating pre-dredge volumes and preparing sediment sampling and analysis plans.
Our team was retained to perform an underwater inspection of Dock 1, review the construction and current condition of the existing dock and design the renewal of Dock 1 in a phased manner. Scope of work included developing several alternates for the construction of new breasting and mooring structures with the estimated construction costs.
