Long Island Utilities
This project for the Boston Public Facilities Department consisted of a 16-building facility and utilities study that was prepared on behalf of the Boston Public Health Commission for its Long Island Campus in Boston Harbor. As a subconsultant, Bryant’s responsibility was to prepare the site/civil and utility section of the report and evaluate the sanitary sewer, domestic water, fire protection and storm drain systems and to prepare recommendations for utility system upgrades along with estimates of construction cost.
The recommended utility improvements were prioritized with the proposed Building Facilities upgrades and build-outs. Furthermore, based on the study, Bryant provided engineering design and permitting services for the preparation of a six-phased construction contract for the utilities upgrades. Completed construction contracts included: a booster pump station and a new altitude valve chamber to support the existing water tank; repairs and repainting of the existing 1 MG water tank; miscellaneous water/sewer/fire protection improvements on campus; replacement of water, sewer, and drain utilities on the campus; and installation of 19,500 linear feet (LF) of 16-inch diameter HDPE and ductile pipe of replacement water transmission main between Long Island and Moon Island. Approximately 3,700 LF of insulated 16-inch HDPE pipe were installed on the Long Island Bridge. Portions of the watermain replacement work included the use of trenchless technology pipe bursting techniques to replace approximately 8,000 LF of existing 12-inch cast iron pipe with 16-inch HDPE pipe.
All of the construction contracts involved extensive coordination with many public agencies and permitting authorities. Permitting activities included Chapter 91 Waterways, Water Quality Certification, US Coast Guard, Boston Harbormaster, Massachusetts Historical Commission, and the Boston and Quincy Conservation Commissions.
