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.
Retained to perform a repair design underwater inspection, develop feasible options for rehabilitation, secure environmental permits, perform final design and detailing, perform construction inspection and management. Static and dynamic mooring analysis were also performed.
Performed an underwater inspection to evaluate the structural condition of structures supporting the gangway and mooring hooks. Provided construction inspection and management services during the installation of gangway and mooring hooks.
Confidential client in SE Arizona commissioned Bowman to conduct construction quality assurance (CQA) for articulated concrete blocks (ACB’s) installed in reclaimed mine areas for spillway down chutes. Verified installation of subgrade, geotextile, filter layer, geogrid, mats, concrete grout lines and anchor trenches to meet manufacturer’s specifications.
Bowman provided engineering services for the detail engineering for the Heavy-Duty Truck Shop (HDTS) traffic area grading and a new truck wash rack to replace existing inadequate infrastructure.
A mile-long concrete channel was constructed at the ASARCO Ray Mine to convey contact water from the Mineral Creek outlet downstream near the mine entrance.

Bowman provided construction management, quality assurance, plant commissioning and coordination between contractors during the commissioning and start-up phase.
Bowman was contracted to scan historic drawings and organize drawing files for easy retrieval using laptops and notepads in the field. Our team migrated existing drawing storage system into BIM 360 input meta-data to allow for easy retrieval of information.
Bowman is providing construction management services that includes mechanical dredging of approximately 1M cubic yards of sediment, haulage, and disposition of dredged materials to a stockpile area 1.75 miles from the reservoir dam.
PLS is stored in a stainless steel lined concrete tank at the ASARCO Ray Mine. During construction, the tank was inspected by several techniques but approximately 35 leaks were detected and attributed to defective and substandard welds. Bowman was asked to inspect and catalog the weld where leaks developed and to work with a specialized welding firm to implement a plan to repair the tank permanently.
