- Sequencing all construction activities in cooperation with the City of Worcester
- Integration of the schedules for the base building and interior fit-out
- Major utility relocations in close proximity to occupied buildings, including a hospital
One Mercantile Place, a significant multi-use development in downtown Worcester, required the demolition of an existing shopping mall encompassing an entire city block, selective demolition of a parking garage, hazardous material abatement and extensive utility relocation to create the site for new construction. Demolition of the mall included over 40,000 cubic yards of concrete and 200 tons of steel. With all major utilities running beneath the site and located within the existing structure, the project also included the cut and cap of utilities, with interior utilities all re-routed including steam, electric, tele/data, hot water, chilled water and gas. Work needed to be precisely sequenced in cooperation with the owners of the adjacent commercial buildings and the leadership of St. Vincent’s Hospital to absolutely minimize disruptions. As a sustainable and cost saving measure, no concrete was transported off-site. The concrete was crushed on-site and reused as fill for the new construction projects.
Upon completion of the demolition Consigli constructed a seven-story, 220,000 sq. ft. office building, to serve as the 700-person regional headquarters of Unum Insurance. The project was executed in two phases – phase one being the core and shell development for CitySquare II which included the renovation of an adjoining seven-story, 800-space open-air garage. Phase two consisted of the interior fit-out for Unum. The project achieved the goals of LEED Silver Certification for the base building and interior fit-out.
