Sitting high on CityPoint near Prospect Hill in Waltham, MA, 245 5th Ave is a prominent new office/lab flex property with an incredible view of the Cambridge Reservoir and surrounding business district.

Featuring 70,000+ square feet of custom unitized curtain wall, the 2500UT system incorporates high performance glass, glazed ACM infills and alternating 12″ and 6″ deep custom tapered fins. Punched out within the unitized wall is another 10,000 square feet of triple-glazed 1600UT curtain wall with projected 24″ box-out accents.

Unitized wall sections spanned 15′ in height passing floor slabs with module widths alternating between 2′ and 6’/7′. Units were hung primarily through the use of slab supported mobile cranes. The Northwest facing box-out features a 25′ tall single-span curtain wall with 15′ lower glass panels weighing over 800 pounds each.

Ground level ACM cladding and a frameless glass entry with glass revolver and monumental insulated glass doors round out the scope on this titan project for Galaxy Glass. Design assist and engineering work started in early 2021 and construction wrapped up at the end of 2024.

With plenty of accent & up-lighting… this one is worth seeing before/after daylight hours.

This new monument at St. A’s was constructed primarily with 1600UT and 1600 Clearwall curtain wall systems. The Clearwall system provides a slick capless appearance while the 1600UT featured an 8″ deep perimeter cover to close off masonry cavities.

Sited at their expansive campus on Middlesex Turnpike in Billerica, this new building for EMD is set to be the future location that will discover the cure for cancer.

Featuring 33,000+ square feet of traditional and 4-sided SSG curtain wall, the building’s design incorporated many large and irregular shaped openings. Lost in scale are the 11′ wide bay openings at the front segmented wall.

Scope ultimately incorporated a revolving entrance, monumental insulated glass doors, a full fit-out suite and a glazed bridge connecting two other buildings.

GGA was responsible for the entire vertical skin of this office building core & shell strip down. The building slabs and structure remained after demo and 18,000 square feet of glass plus 14,000 square feet of panels gave the old brick building a much needed face lift.

Panel scope primarily consisted of insulated metal panels with ACM accents at the entry canopy and roof structure wrap that included custom grille inserts.

Glazing included ribbon window storefronts and 2-sided SSG curtain walls at the Southeast facing facade overlooking I95 through Waltham. The curtain wall featured a custom 9″ deep face cover with integral lighting channels that house LED strip lighting with wiring run back through the mullion tubing for a clean/wireless look.

With a prominent front curtain wall featuring integrated sunshades, this HQ expansion features long runs of stick assembled “can” storefront ribbon windows. ACM cladding crowns the front tower while interior scope included framed aluminum office fronts and glass guard/stair rails. Exterior glazing features an “arctic blue” outboard substrate.

Exchange 93 is located in Braintree where 95 meets back up with 93 North.

Clean and simple, this project featured 16,000 square feet of 1600 screw spline curtain wall.

Sitting at the gateway to the Wells Avenue business loop in Newton, MA, Two Wells Avenue is a prominent addition boasting loads of modern glass facades mixed with composite metal and wood grain phenolic resin panels throughout. The use of curtain wall framing systems at all openings allowed for the continual integration of the AVB membrane within the glazing pockets. In addition to the narrow 2″ sight line captured strip curtain walls, the forward elevations made use of 4-sided SSG glazing set with 3M’s VHB tape applied cassettes. It’s just about as clean of a look as you can get with a curtain wall!
