Cumberland Farms Action Plan
   Florida

Overview
The remedial action plan for this leaking underground storage tank site included excavation of contaminated soils. The plan specified the installation of sheet pilings to support the excavation during dewatering. Unexpected soil conditions complicated installation of the pilings. These difficulties caused noise and vibrations that brought neighbors to the site with complaints. The site manager, Scott Burgard, called a temporary halt to the operation and reviewed his options.

An alternate excavation method that could be accomplished without sheet pilings was selected while the work team was still in the field.

• Remedial design.
• Remedial action.
• Subcontractor management.
• Permitting.

Results
This revised plan was implemented within the original project schedule and budget. Negotiations with local utilities resulted in an agreement that allowed water removed from the excavation to be discharged into the sanitary sewer. Eliminating the costs of on-site treatment, in combination with the money conserved by the alternate excavation method, resulted in a cost savings of $80,000.
