Cambridge-based HMFH Architects Inc. and Milford’s Consigli Construction Co. Inc. has completed the second phase of construction at the Cambridge Rindge and Latin School (CRLS) in Cambridge.

Over the course of two years, the $85 million multi-phase renovation will revitalize 400,000 square feet of the high school’s academic space, originally constructed in 1933 and expanded in 1978. Final renovations will be completed in time for the 2011 school year, according to a statement.

CRLS is the only public high school in the city of Cambridge, with a capacity of 1,800 students and a continuous history dating back to the founding of Harvard College. In keeping with the city’s green buildings policy, CRLS is expected to be LEED Silver certified when it is completed.

At the Rindge Building, the team renovated classroom spaces with new walls and floors, and installed new light fixtures, plumbing systems, ceilings, windows, sprinklers and high-efficiency HVAC systems. In the arts building, improvements include a new roof and roof-mounted HVAC units. The stone façade was restored to preserve the exterior surfaces of limestone and concrete.

"This has been a challenging project that was initially driven by specific building system replacement needs and expanded to address operational, educational and community needs," said George Metzger, president of HMFH Architects. "CRLS serves an important role in the Cambridge community and we are pleased to have played a part in revitalizing this landmark educational environment."

"Important improvements for the Cambridge Rindge and Latin School have been achieved through comprehensive phasing conducted by a team experienced in fast-track renovations," said Jim Hervol, project executive for Consigli. "We’re proud to be a part of the team responsible for creating an educational resource for the city of Cambridge."
