Fairfield Metro Center

Fairfield, Connecticut

Services: Remedial Design and Feasibility Study
Clients Served: Real Estate Development

The site for the Fairfield Metro Center is approximately 35 acres and is located on Black Rock Turnpike in Fairfield, Connecticut. The site was the former location of a foundry used to manufacture large machine tools. The 50 years of industrial activity had resulted in the placement of over 250,000 cubic yards of casting sand (a byproduct of foundry operations) and a number of releases of volatile organic compounds and oils containing polychlorinated biphenyls. After receiving mixed opinions regarding the nature and extent of contamination and the best approach to remediate the site, Loureiro was retained by the developer to provide an expert opinion on the most cost-effective approach to remediation of the property.

Loureiro quickly and cost-effectively assimilated over 20 years of environmental investigation and remediation activities to develop a remedial action approach well integrated with the overall proposed redevelopment of the site as a mixed use commercial transportation center. The remediation approach involved the excavation and onsite reuse of contaminated soil and casting sand followed by the placement of an engineered control over greater than 18 acres of the site and the restoration of over 2,600 linear feet of shoreline. The engineered control was integrated into the overall redevelopment design and was designed to maximize the land area available for the creation of landscape features. The remediation approach also calls for the placement of contaminated soil and casting sand beneath parking garages located under proposed buildings. In total, the remediation approach we have developed results in the maximum onsite reuse of impacted soils and a savings in excess of $19,000,000 in comparison to an excavation and offsite disposal alternative previously considered.

Loureiro prepared detailed design plans and technical specifications and was retained to provide onsite construction observation throughout the remediation project. The design was constructed without the need for specialty contracting and the promised cost savings was recognized.
