Capabilities and Experience

Sevenson is one of a few remedial action contractors with roots in general construction. This general construction background enables Sevenson to look at a particular site remediation project from a practical, operations oriented point of view. This often leads to ideas for cost savings through modest changes in the project plan which can yield significant cost savings. As a hands-on contractor, Sevenson prefers the greater operational control of performing a project with its own forces as opposed to using subcontractors. Consistent with this policy, Sevenson owns and maintains its own fleet of traditional and specialty construction and marine equipment.

Sevenson's projects require a range of services including:

• Excavation and earthwork;

• HTRW materials handling, processing and treatment;

• Innovative and traditional steel sheeting systems;

• Dredging, dewatering and volume reduction;

• Sediment remediation;

• Chemical treatment/heavy metals fixation;

• Collection, recovery and treatment systems construction;

• Facilities decontamination and demolition;

• Bioremediation; and

• Constructibility review and design phase consulting.
