NYC Issues Criminal Charges after Ironworkers Injured in Crane Incident

Two men have been charged with two counts of assault in the second degree by New York City authorities following an investigation into a mini crane accident that injured two ironworkers in June 2018. The incident occurred at the Gotham Residential Project in Harlem where a Jekko mini crane fell several stories during a curtainwall installation. Terrence Edwards, 39, and Timothy Braico, 41, now face criminal charges.

Blumenfeld Development Group, the owner of the building, hired ZDG LLC as construction manager in 2016. ZDG hired Western Waterproofing Company Inc. as subcontractor to install the building façade.

According to a release from the Manhattan district attorney, Braico, the senior branch manager of Western’s Ridgefield, N.J., branch, ordered a mini crane to be delivered to the Harlem site, even though none of the workers onsite were trained to operate it and permission had not been obtained.

The district attorney alleges that on June 25, 2018, Edwards, the site superintendent, directed an ironworker to hoist glass panels from the second floor up onto the fourth floor where the crane was located. The operator was not trained to use the mini crane and, as a result, did not understand its load capacity. He was not told to tether the mini crane.

According to the district attorney, Edwards directed Christopher Jack-son and Jorge Delgado, both members of Ironworkers Local 580, to guide the glass lites into place from the floor below the crane as the crane operator hoisted them up to the fourth floor. While lifting a heavy glass lite, the mini crane lurched forward and capsized before falling four stories to the ground. The crane’s boom knocked into Jackson on the third floor as it fell, breaking his harness and catapulting him to the ground.

“Jackson suffered severe trauma to his head, resulting in a traumatic brain injury which has affected his ability to speak and to walk. Delgado was struck in the back, and suffered severe spinal injuries impairing his ability to walk and move,” reads the release.

Western entered into a deferred prosecution agreement. According to the district attorney, the company agreed to retain an independent monitor, enhance safety training for its workers and fund public service announcements in English and Spanish to educate workers around New York about their right to a safe workplace.

Braico and Edwards face two counts of reckless endangerment in the second degree on top of the assault charges.

ASHRAE 90.1 Proposal Could Impact U-Factors

Changes that impact the glass and glazing industry have been proposed to Addendum AW to ANSI/ASHRAE/IES Standard 90.1-2016, Energy Standard for Buildings Except LowRise Residential Buildings.

For climate zone 5, the fixed fenestration coefficient for nonresidential and residential spaces has been adjusted from the initially proposed 0.36 back to 0.38. According to the public review draft, the change accounts “for the different frame ratio used in NFRC calculations for curtainwall products compared to the window wall products used in the analysis.”

The second major change involves residential skylight U-factors. In zone 6 where there are significant snowloads, the U-factor has been adjusted from 0.47 back to 0.50 to account for limitations in curb-mounted unit skylights, according to the draft. Cost effectiveness will not be impacted be-cause the corrections restore values currently in the 2016 edition.

American Architectural Manufacturers Association (AAMA) technical director Steven Saffell submitted a public comment on AAMA’s behalf criticizing the previous decision to lower the U-factor maximum.

“Achieving the proposed 0.47 requires a significant cost increase for the glass package and/or a smaller air space. The latter could create challenges for supporting snowloads, which are a major design consideration for much of Climate Zone 6. We believe the savings from the minimal U-factor reduction sought does not justify the added cost,” he wrote.

The final change is an upward adjustment of the skylight U-factors in semiheated spaces in zones 2-8. The adjustment will allow the inclusion of more product options.

The proposed changes to Addendum AW were open for a second public review until December 16, 2018.
