Crews tasked with upgrading the Portsmouth Wastewater Treatment Plant in the same footprint as the existing plant due to space constraints on Peirce Island had to maintain treatment operations and public pool access.

The project involved careful planning and construction to rehabilitate 113 Brattle St.—one of Cambridge’s most historic addresses—as well as build an expansion onto the back of the building.

Working in a densely populated area of Cambridge posed many challenges for this restoration project, including constructing an apartment building to Passive House standards, working with challenging soil conditions and managing odd geometries at a site near other residential properties.

The project had two main goals: to preserve the historic original home of the Federal Reserve Bank of Boston and accentuate its architectural elements while also modernizing the hotel to meet modern luxury standards. The early 1920s R. Clipston Sturgis-designed Renaissance revival style makes up 288,000 sq ft of the hotel.

Located on a 6-acre site in Greater Boston’s innovation and life sciences cluster, the five-story, 500,000-sq-ft office and lab building provides a flexible, column-free floor plan to maximize custom interior layouts and provide structural and building system capacity for tenants.

This 360,000-sq-ft high school replaces one built in the 1970s.<

EMD Serono hired Erland to construct an amenity-focused building to add more lab and office space and augment the vibrancy of its growing campus.

When COVID-19, supply chain issues and other factors threatened this 203,000-sq-ft R&D fit-out, the project team collaborated on alternatives to keep it on track.

One of the state’s busiest exits was upgraded to handle higher traffic volumes via a two-part project that combined structural rehabilitation of underpass bridges, ramp realignment, mainline reconstruction and replacement of an existing toll plaza with open-road tolling technology.

This exceedingly complex and challenging project provided a 75-year design life for the structurally deficient critical link between the city of Chelsea, Mass., its northern suburbs and Boston.
