A topping off ceremony was held recently to celebrate the placement of the last piece of steel on the 86,000 s/f addition at Genzyme's landmark Allston Landing biomanufacturing facility along the Charles River. The Allston expansion is the latest collaboration between ARC and Genzyme, a partnership that dates back to 1991 when ARC designed Genzyme's original Allston facility. Since then, ARC has designed more than one million s/f of new construction and renovation projects for Genzyme, including the brand new 177,000 s/f Science Center in Framingham. Allston Landing is Genzyme's premier protein manufacturing facility. Turner Construction Company serves as the general contractor for the project.
