With so much preparation work having taken place, it is time to dismantle the sheathing facing the canal and Roosevelt Drive. It's likely at this stage in de-construction that residents or passerby will wonder what is going on, and thus this communication stream.

The following photos were over just a couple of days.

The interior of the building is now broom clean with all decking, pipes, electrical, lights and insulation removed. Everything except the insulation and roof materials in the 42,000 sqft building was recycled for it's scrap metal value. The only thing left on the floor is the vertical supports, with connections between the rows which tie it together as a structure with rigidity. The outside sheathing is attached to girts that run the full perimeter.

The view up the river valley is spectacular on a clear day like today. The Yale University Boathouse is barely visible in this one-point perspective photo.

The building's footprint is apx. 42,000 square feet. The racks are over 30 feet high. This yielded 1.2 million cubic feet of storage space. Sadly, it has gone vacant for over 30years due to inability to heat the space and offer something other than "cold storage", and the lack of freight elevator accessibility as would be called for with modern warehouse standards.

The "erector set" of racks is simply held together with pins, and the gravity of the steel horizontal beams holds them in place. These components have been in place since the 1960's, and the structure vacant from use for over 30 years. As such, water that was standing on the floor from roof leaks had caused deterioration to the steel in a few places. The photo shows how rust has eaten like a cancer up this particular vertical support. Unlike structural steel (such as i-beams), rolled steel material is lighter and more susceptible to rust over time. In the few places where regularly in standing water, it thus causes significant rust penetration. This has simply become a safety matter and the structure had to be dismantled.

At this stage, the Rack Storage structure has had all of it's roof decking as well as internal accessories removed. It was important to keep the various materials separated: cast iron drain pipe, sheathing sheet metal, roof decking corrugated steel, shelving steel, etc. Fortunately, we have a large yard to sort and separate the materials as seen in adjacent photo.

Keeping materials separated and uniform allowed efficient loading on trucks for consolidated delivery to the scrap yard, and yielding the best scrap price for semi-prepared materials rather than simply dumpsters filled with various components. It also allowed us to make the scrap deliveries ourselves rather than with large containers.

The rear of the structure was our first attempt because it was a bit more complicated. After the fire from the mid 1980's, when the State of CT seized the property, and subsequently sold it to the City of Derby, it was prepared to be marketed as an industrial park. As you might imagine, there were some shortcuts taken in that governmental preparation. On some parts of the structure, they left the existing siding and put on some "Z" girts for attaching a second layer of siding that was more aesthetically pleasing. In between was a layer of insulation, which seems strange since there was never any form of heat provided within the structure.

After the first layer was removed, insulation pulled away, and the second layer of sheathing removed, it left exposed the simple erector set of the storage racks. With this accomplished, to speed the progress and minimize the disruption as witnessed from the street, we removed all the coping that bridged between the siding and the roof (which was removed first).

Our next blog entry will show how the preparation paid off with quick work and minimal disruption to the street facing the Canal. Note: while "Canal Street" is technically closed due to a construction project by the United Illuminating electric utility, it is still important to minimize disruption of access for any emergency responders.

Dismantling the "rack storage" structure would require some planning. First, we front directly on what is assumed to be a City street "Canal Street", when the fact is that it is technically a "common pass-way", a relic from the old manufacturing days. Regardless of the legal aspects, the work to be conducted would require closing the road from any use for safety reasons. The electric utility had some work to replace underground vaults in August where there was a formal notice of closing for a month - so we synchronized our opportunity to occur during that time.

The racks themselves are a heavy steel upright with perforated holes where horizontal beams sat on pins with gravity. It was on those beams that corrugated steel shelving was placed, and upon that shelving where product was stored when the storage structure was utilized. Removal would be as simple as dismantling an erector set, but just needed to be done in a proper sequence.

Since we utilize talented and trained staff in construction, it seemed wise to use the same staff to accomplish some de-construction. We allocated time in our schedule of upcoming projects to make use of our existing workforce in an efficient manner. All workers on site are trained in use of boom lifts, scissor lifts, fall safety, and other regulations related to OSHA that one would expect on a construction site.

The roof would come off first, and it was an EPDM type rubber roof with a build-up of styrofoam to create pitch toward the roof drains. This was compromised several times over the years. The photo to the left shows damage from 2003Nov. It was repaired, yet damaged again in 2004, and the photo on the right shows damage from 2006Mar. At certain points the roof has 11inches thick of the styrofoam to create pitch toward roof drains. The first step was to remove the roofing materials and dispose of it. While styrofoam can be recycled, the moisture and contamination from dirt and rust made that impossible and this was the only component of the building that was hauled away as waste.

Many interior components were removed during this time, all the light fixtures, wiring, roof drains with piping, sprinkler system, and shelving were all systematically dismantled and collectively separately hauled to a scrap storage facility for recycling. As an example, segregated piping shown on left, shelves and roof decking on the right loaded on truck for delivery to scrap yard.

Now with solely the structural elements in place, the erector set could be removed in sequence. Our next blog entry will illustrate how this was accomplished.
