Building NW23

The building renovation of Building NW23 is underway at 195 Albany Street. A crane is on site to access the roof and existing equipment on the roof will be demolished. Work hours will be 7 AM to 3:30 PM. The renovation has a target completion date of late January 2016. When the project is complete, NW23 will serve as the new home for the Department of Facilities and the Office of Campus Planning.

A former lab building, NW23 will receive new windows, a new roof, and new interior spaces as well as new mechanical, electrical, and plumbing systems. The shared main entrance will be completely renovated to create a reconfigured lobby and accessible walkway. As part of this project Building NW22 at 185 Albany Street will receive new windows.

Most of the work will take place inside the building, which will help control noise levels, but the community can expect to hear a moderate level of noise as materials and equipment are delivered to and removed from the site. The process of removing the concrete sidewalk and building entrance is also expected to cause localized noise. In addition, the community can expect increased traffic on Purington, Pacific, and Albany Streets, and a reduced number of parking spaces in the lot just west of NW23 (part of the lot will be used for construction support activities).

During the renovation of the main entrance, pedestrians will be directed to use an alternate entrance. This will be coordinated with the building occupants at a later date once the schedule and alternate route is finalized.

Collier Memorial

Construction is underway for the installation of a permanent memorial to Officer Sean Collier, who was killed in active service to the MIT community in April 2013. The memorial was conceived and designed by Meejin Yoon, Professor and Head of the Department of Architecture at MIT, and is expected to be completed by April 2015.

The memorial will stand at the intersection of Vassar and Main Streets, where there is now a small garden between the Stata Center and the David H. Koch Institute for Integrative Cancer Research.

Walkways around the site will maintain pedestrian access to the North Court from the corner of Vassar and Main Streets throughout construction. A traffic lane will be maintained between the site and building 76 for emergency and authorized vehicles. Police details and signage will direct pedestrians through the area as needed. Work hours are 7 AM – 3 PM.

Constructed like a complex puzzle around a central keystone, the Collier Memorial will comprise five archways in the shape of a protective yet open hand. As Yoon has designed it, the structure is built of solid granite to embody strength and encompasses a void at the center that evokes the absence of a large figure. Read about the design and engineering of the memorial.

Questions about the Collier Memorial construction may be directed to Paul Murphy.
