Scope: On our first wood fiber insulation project, we achieved significant savings by combining early plan review and value engineering with careful management of change orders related to unanticipated structural repairs in this 120-year-old building. The resulting contingency fund surplus was applied toward construction of a high-performance, Passive House exterior envelope and hyper-efficient HVAC systems -reducing energy consumption per square foot to 69% of conventional code construction. All 20 affordable units will enjoy enhanced comfort and low utility bills while knowing they have significantly reduced carbon emissions.

4 Mellen Street restores a prominent, nationally-registered historic building that once served as the Lesley University admissions building and originally as the 1860’s home of a Cambridge mayor. A six-story Passive House addition creates 29 new affordable homes on a difficult, tight site. As OPM and Clerk of the Works, TDS personnel completed a detailed drawing review to identify issues early so the design team could resolve them before construction. When structural problems were uncovered in the existing foundation, TDS closely managed the budget and all change orders, helping the team balance the Cambridge Historical Commission’s preservation requirements with modern energy performance goals. TDS also oversaw the air sealing and insulation work to ensure the project met both Enterprise Green Communities and Passive House standards.

Scope: Every development project begins with a vision, and on this Mass Timber project at Dana Street, our role has been to transform that vision into reality.

To answer that, we paired them with a general contractor experienced in providing real-time insight on construction costs and schedules. We also introduced the owner and contractor to Blueprint Robotics, a leader in panelized construction and Mass Timber systems, crafting solutions to control costs without compromising the sophistication needed to succeed in Boston’s competitive real estate market. By rethinking traditional methods and leveraging modular building solutions, the project now benefits from significant time and cost savings without sacrificing design quality.
