2019 ABC Silver Medal Winner

With the Woolfolk Building re-roof project, Malone embarked on an ambitious trajectory to prove that we could roof one of the tallest most complex roofing structures in the state. As of July 2019, Malone has accomplished that mission.

Malone was one of only three bidders on this challenging project. The challenges lied with access to the roofs, the height above ground level, tie off capabilities and the confined nature of certain work spaces.

The project consisted of 25 separate roofs on elevations ranging up to 190 feet. This project was 49,000 square feet

The roof assembly was as follows: Removing the existing lightning protection and roof system down to the structural concrete deck, Adhere a ¼” tapered insulation with a 3” minimum thickness sloped to internal drains, adhere a ½” dens-deck prime cover board, torched 1 ply of Firestone SBS Glass Torch Base and 1 ply of Firestone SBS FR Torch Cap, flashed with vertical surfaces and penetrations with 1 ply of Firestone SBS Glass Torch Base and 1 ply Firestone Metal Flash AL, metal counterflashing was fabricated in .040 aluminum.

The lightning protection was reinstalled with new parts as needed for recertification as well. What made install of tapered insulation such a challenge was due to the very confined work areas and the sheer volume of materials.

Simply put, multiple layers of insulation, virtually no access and small work space equals a tough challenging environment. In regards to access, some of the roofs could only be accessed from the air. Meaning materials and crews had to be air lifted with a crane plus a material bucket or man basket accordingly.

Furthermore, one particular large chiller for the Woolfolk building’s HVAC required our crews to crawl under and out, while working on hands and knees, for 3 weeks, with only 2 ½ feet of clearance space.

Safety on this job, in particular fall protection, is always of utmost importance. On this project, Malone crews worked at high elevations with low parapet walls, this translates to 100 percent safety tie off for the entire job.

This meant nowhere to tie off, with a small work area, 150 feet in the air. Therefore, Malone found parapet clamps that attached to the tops of the parapet walls and then our crews attached to the secured clamps. There were no safety plan failures or injuries throughout the entire project.
