Frog Switch - Carlisle PA - Supplemental Phase II Environmental Site Assessment

The Department of Transportation’s Office of the Secretary is soliciting services for a Supplemental Phase II Environmental Site Assessment at the Frog, Switch & Manufacturing Company property in Carlisle, Pennsylvania. Building upon a 2025 assessment that identified soil contamination from metals and polycyclic aromatic hydrocarbons, this project aims to further characterize impacts across the 31-acre site. The primary objectives include delineating specific areas of contamination through expanded sampling and establishing a standard for naturally occurring arsenic by collecting background samples. The investigation area consists of relatively flat terrain with silty clay soils underlain by limestone at depths ranging from five to 32 feet.

This solicitation, identified by number 6913G626Q300023, is designated as an SBA Small Business Administration set-aside. The project is categorized under NAICS code 238910 for Site Preparation Contractors and PSC F999 for Other Environmental Services. Performance will take place at the 600 East High Street facility in Cumberland County. Seven attachments accompany the notice, including a statement of work for supplemental drilling, a field sampling plan, instructions to offerors, evaluation criteria, and a summary of clarification questions and responses.

Submissions for this opportunity are due by May 4, 2026. Roland Regan serves as the primary point of contact for the procurement. The scope of work is detailed across multiple documents, including FAR and TAR clauses and specific site boundary information provided in the investigation attachments. All activities will be conducted at the Carlisle, PA location, approximately one mile west of the intersection of Interstate 81 and Pennsylvania Route 641.
