Metal Stud Framing

Carpenters working for H. Carr & Sons, Inc. are currently working on the metal framing throughout 1st and 2nd floors.



The interior of Commercial buildings are framed out using metal stud, instead of wood frame, because there is no load being carried by the walls. The steel structure of the Carpenters Center carries all loads for the building. Even in wood frame construction, interior partitions are done by metal studs because they are faster and less expensive to install. Today, many single family residential properties use metal stud for interior walls that are not load-bearing.

When the carpenters finish framing out all of the walls, the electricians will pull wires and locate receptacles, Tele data boxes, switches and lights throughout the building. In wet walls (kitchens and bathrooms) the plumbers will install the rough plumbing. After electrical and plumbing is complete, the drywall will be hung.



In addition to the interior metal stud work, carpenters have also framed out the parapet wall on the roof. The Boston Redevelopment Authority requires that all something is put in place to conceal rooftop mechanical units. For the Carpenters Center a parapet wall was designed, which will act both as a windscreen and concealment of the rooftop units. Instead of simply building fencing around the rooftop units, as is often seen at the top of buildings, the Carpenters Center will have a parapet which fulfills the BRA requirement but also is a design feature of the building.



The Den Glass is installed on to the metal frame; much like drywall will be installed on the interior walls of the building. After the dens glass is completed, 3.5 inches of insulation will be put on the roof, then the roofing can be installed.

In addition to the metal stud work, MEP (mechanical, electrical, plumbing) continues on the second and third floors.


Fireproofing is being done by crews working for Advanced Spray. The fireproofing is sprayed onto the entire steel structure of the building. On areas where the steel will be exposed (i.e. in the pavilion) fire resistant intumescent paint will be put on the beams instead of the spray fireproofing. Intumescent paint creates a fireproofing around the steel structure. Under extreme heat the paint will actually expand up to 6 times its thickness, protecting the steel from the heat/fire.

Mock-up panels ready for BRA

Carpenters working for Sunrise Erectors completed the mock-up on site, which offers a visual display of look and color of the Carpenters Center upon completion.



The mock-up is a requirement of the Boston Redevelopment Authority (BRA). The BRA has authority over all new building development in the city, part of what they do is ensure that designs chosen for new construction fit in with the existing neighborhood’s character. On this site, the BRA is particularly concerned with the colors and their effect on the neighborhood.

The responsibilities of the BRA include, among other things: reviewing proposed development projects; making recommendations on major construction and redevelopment activity to the city’s Zoning Commission; and drafting master plans that address the city's needs for infrastructure, downtown and community economic development, and that include design guidelines and development controls. For more information, visit the BRA's website.

Carpenters working for Sunrise Erectors finished the mock-ups with the installation of windows and Alucobond Panels that will cover the exterior of the building. The mock-up panels consist of six colors, 4 color panels and 2 reveal colors (charcoal and bronze in this picture) and a section of cedar siding (running along the bottom).

The mock-up up will be reviewed by the BRA and will remain on site for the duration of the project.

Eastern District Vice President tours Carpenters Center

Cross posted on www.nerccblog.com

On June 15, 2009, Mark Erlich, Executive Secretary-Treasurer of the New England Regional Council of Carpenters, gave a tour of the Carpenters Center to Frank Spencer, Eastern District Vice President of the United Brotherhood of Carpenters.

Third Floor Concrete Work Complete

Cement Finishers and Laborers working for S&F Concrete completed the concrete pour on the third floor of the building earlier this week.

After the Q-deck was shot in place, WWF (welded wire fabric) was laid out on top. The WWF serves as reinforcement for the concrete keeping it from expanding to the extent where it will then collapse. The concrete was then pumped into the 3rd floor Q-deck.

Over 350 yards of light weight concrete was poured into the 26,000 square foot space. The work was completed in 12 hours.

Concrete Work Continues at Parking Garage:

Concrete work continues this week at the parking garage. Here carpenters can be seen working on the forms.





Last week, the concrete was poured for the columns supporting the parking deck.


To see the columns before the concrete was poured check out last week’s post.


Below is a video of concrete work in action. The film was shot in April and includes work on the foundation as well as the pavilion section of the building.

Video Update- May Recap

Carpenters Union 'tops off' new HQ

As reported in the Boston Business Journal:

The New England Regional Council of Carpenters held a ceremony with Suffolk Construction Co. Inc. to place the last beam of steel on its new headquarters.

The “topping off” as it is called, was held in Dorchester where the 75,000-square-foot facility is being constructed. The carpenters are converting an abandoned two-story industrial building next to Interstate 93 into a trade school that will train 2,000 students a year. The building will also house union offices, a bank and an eye care center for union members.

Those in attendance included council officials and the contractor, Suffolk Construction, as well as the architect, ADD Inc., and engineers RDK Engineers and Goldstein-Milano Structural Engineering and trade workers.

The New England Regional Council of Carpenters has been looking for a site to accommodate a new headquarters for the past decade. The building is scheduled for completion in January.
