PHP ROOFTOP SUPPORTS - CASE STUDIES

Texas Department of Criminal Justice, Stiles Prison Unit, Case Study

Situation:

The Texas Department of Criminal Justice's (TDCJ) prison, the Stiles Unit located in Beaumont, Texas, had serious problems with their roof and air systems. The project required replacing the old roofing system, removing old ductwork from the mezzanine, and supporting new ductwork on the roof. As a result of hurricanes Katrina and Rita striking the area in 2005, the project required extra-strong roof mounting equipment. Texas Department of Criminal Justice Construction Management required the roof-mounted equipment be able to withstand 120 mph winds.

Solution:

The design and layout of the new systems were completed within 48 hours. The outsourced engineering took approximately seven days. PHP designed a roof and duct support system minimizing roofing penetrations. In addition, heavy-gauge cable restraints were implemented to secure the large amount of ductwork on Building 12. The standard five-year limited warranty applies to all installations.

Results:

TDCJ was able to save in excess of $100,000 since curbs or structural supports were not used. There were minimal roof penetrations and stamped drawings were provided to TDCJ by a licensed Texas P.E. The project, valued at $4 million, began in August 2007 and is still ongoing.

 

Starr Elementary School, Fresno Unified School District, Case Study

Situation:

On the weekend of September 8, 2012, Starr Elementary School was hit by vandals. This is nothing new. Other school districts face this problem day in and day out. One of the vandals picked up a metal pipe or bat to break the skylight to gain entry into the school.

Solution:

A PHP hurricane glass skylights installed the previous year during the re-roofing would not break. Starr Elementary chose the hurricane glass model because of the 20-year fall protection warranty. They had no clue as to the benefits this would have towards vandalism.

Results:

The vandals hit the skylight with a bar so many times to try to gain entry that it woke up surrounding neighbors who in turn called the police. The vandals scattered at the sound of the sirens and were fortunate to escape. There is not doubt that the PHP skylights kept them out. Who knows what damage the school would have incurred.
