Overview

Summary

This project includes the environmental remediation of 198 River Street and associated limited site improvements at 194, 198, and 200 River Street to support the redevelopment of 198 River Street by a private developer. The project will consist of four distinct phases. Phases 1, 2, and 4 will be completed under this contract by the City's selected contractor. Phase 3 will be completed by the private developer and may require temporary demobilization of the City's contractor while the private developer completes the Phase 3 work. The anticipated construction duration for Phases 1 and 2 is 84 calendar days. The duration of Phase 3, by the private developer, is anticipated to be 30 days. The duration of Phase 4 of the project is anticipated to be 60 calendar days.

Phase 1 (remediation) includes the demolition and disposal of polychlorinated biphenyl (PCB) contaminated concrete slabs at 194 and 198 River Street; excavation and disposal of contaminated soils (PCBs greater than 50 ppm and other contaminants) from three remedial excavation areas at 198 River Street; along with dewatering, treatment, and discharge of contaminated groundwater to the sanitary sewer to complete the excavation of one of the remedial excavations. Phase 2 includes installation of temporary support of excavation along River Street, excavation for the foundation of the proposed building, construction of a retaining wall, and backfilling and compaction of the site to grades specified to prepare the site for Phase 3. Phase 3 will be completed by the private developer and consists of construction of the proposed building foundation (footings and foundation walls). Phase 4 includes finalizing the temporary support of excavation, backfilling and compaction of the site to final subgrades for construction of the paved parking areas at 194, 198, and 200 River Street, installation of an on-site stormwater drainage system at 194 and 198 River Street, installation of underground electrical service and light poles at 194 and 198 River Street, installation of tree pits at 198 River Street and along River Steet itself, installation of the bituminous binder course at 198 River Street, and repair of the existing sidewalk and curb along River Street and pavement in the roadway of River Street after installation of service laterals (sanitary sewer, water, and natural gas).

This project is funded, in part, by a grant from the State of Connecticut. The contractor who is selected to perform this State funded project must comply with CONN. GEN. STAT. §§ 4a-60, 4a-60g, and 46a-68b through 46a-68f.

(25% of the total state-funded value with DAS-certified Small Businesses and 6.25% of the total state-funded value with DAS-certified Minority-, Women-, and/or Disabled-owned Businesses.) The contractor must demonstrate good faith effort to meet the spending allocation goals. Bidders shall review the State of Connecticut Department of Economic and Community Development (DECD) Bidding, Contracting, & Procurement for Construction Guidelines for DECD Programs, January 2026 revision, which are included as an attachment to the bid documents, and become familiar with all applicable DECD bidding requirements.

Background

The parcels were formerly occupied by the Bigelow Boiler Manufacturing Company, which originally began operation at the site in 1869. Historical operations at the site have resulted in contamination of the existing sitewide concrete slabs and site soils. This Brownfield site is located within the River Street Municipal Development Plan District and remediation and redevelopment of the site is a critical component of the City's redevelopment plans for the area. Remediation of the site is being funded by the Connecticut Department of Economic Development through a Municipal Brownfield Remediation Grant. Remediation of the site must be completed in accordance with the Connecticut Release-Based Cleanup Regulations (RBCRs), the Self-Implementing On-Site PCB Cleanup & Disposal Plan (SIP) dated July 19, 2024, and the associated SIP approval letter issued by the U.S. Environmental Protection Agency dated March 26, 2025.
