Concrete Block and Brick Removed

In addition to completing the dismantling of the steel structure of the second floor, NASDI has completed the demolition of the building's walls.


After the second floor beams and columns came down, the brick and concrete block were removed from the entire building.




This is a picture of the building before construction began:



Here is the structure on March 6th. The second floor has been entirely removed, as well as the walls on the first floor.

Roof is gone, steel skeleton dismantle begins

The roof of the existing building has been completely removed.


Here’s a shot from just a week ago when the roof removal had just begun:



With the roof removed, crews started dismantling the steel skeleton of the second floor.


The steel beams that were once under the roof are removed first. Instead of undoing each bolt that holds the beams in place, the crews actually cut the beams out but burning them at each end (pictured below). Once all of the beams are down, the columns will be removed in a similar fashion. The majority of the column is removed using the burning technique, however the base of each column will is removed by undoing the bolts where the column attaches to a steel plate in the concrete floor.

Sign Mock-Up on Display

On Monday, representatives from the Carpenters Union, ADD Inc., and Sensory Interactive were on hand for a product demonstration of the transparent LED display that will be a part of the new Carpenters Center.

Seen below in the rendering of the new building, the sign will be located on the Expressway side of the building, visible from traffic traveling Northbound on I-93. The displays that were on hand Monday were mock-up sizes of the actual sign, which will measure approximately 32 feet high by 22 feet wide.

The display is transparent, meaning that from the inside of the building you will be able to see through the display to the Expressway, even when the sign is turned on and displaying a still image. The sign is made up of rows of LED lights, allowing this visibility from the inside of the building out.



The mock ups were lifted into the air by a crane, which allowed onlookers to get an idea of the brightness, viewing angles, and viewing distance of the LED Display in both daylight and at night.

The Carpenters Union is working with Sensory Interactive to finalize the details of design and final approvals.

Roof Removed

Crews began removing the roof from the existing building. Excavators were brought in to the second floor to remove the roof off the concrete slab.

The following shots show the center section of roof being removed.

Interior Partitions Removed

The demolition of the interior partitions on the first and second floor is complete, including masonry, metal stud and drywall. The debris was separated for recycling, as part of the LEED certification process.

The debris is removed from the interior of the building and then loaded into dumpsters located outside. As the debris is dropped outside, it is sprayed with water to prevent the spread of dust through the air (pictured below).



Following this cleanup, NASDI will remove the air handlers on the roof, such as air-conditioning and heating units, and then the entire roof will be removed. This will happen from the interior of the building. An excavator with demo claws will be brought into the second floor to take the roof off the slab.

Asbestos Abatement Complete

The abatment process was completed today, two days ahead of schedule. Demolition of interior partitions is scheduled to begin tomorrow, February 12th.
