The Total Package

With a wide range of in-house capabilities, Moretrench’s Tampa office can provide turnkey services for large industrial projects.  For a West Central Florida power plant, this included site dewatering, installation of several thousand feet of large-diameter pressure pipe, precast electrical trench installation, storm drainage, dredging, grading, construction of asphalt roads pavement, rock surfacing and grass restoration.  Pipeline alignment crossings beneath active high voltage transmission lines and a natural gas line added to the challenge.

 

Ash Dewatering at Work

At a power station in the mid-Atlantic region, fly ash, bottom ash and boiler slag from discontinued coal-fired operations is stored in five surface impoundments, some of which date back to the mid-1950s.  Acting in compliance with current environmental regulations, the owner is moving ahead with plans to consolidate the four smaller impoundments, which are unlined, into the fifth and largest of the ponds, which will ultimately be capped.  In the first phase of the consolidation work, Moretrench was contracted by the General Contractor to dewater a 37-acre pond.

Fraser River Deep Freeze

Mining of Metro Vancouver’s new Port Mann Water Main beneath the Fraser River was well underway and the TBM was approximately 650 ft from the north bank exit shaft when an unanticipated mechanical failure occurred in the cutter head, halting mining operations.  Fast-acting liquid nitrogen ground freezing  proved to be the best solution to allow safe access for inspection and repair.

 

South American Deep Freeze

When all previous efforts failed to halt soil and water ingress into a deep shaft under construction in Buenos Aires Province, Argentina,  Moretrench was called in to provide a ground freezing solution that successfully resolved the issues, allowing excavation to continue to final depth in the dry.

For every infrastructure megaproject, there are as many small, typically unsung but vital components as there are large, more newsworthy sections. Yet without these smaller components, the overall project may not…
