Tilt-Up Goes to School!

Utilizing tilt-up construction for educational facilities just makes sense. The facilities have a much lower life cycle cost because they take advantage of the durability and longevity of concrete.  In addition, there are no design limitations, anything you can form, you can pour. This flexibility allows designers to put the mark of the community on the facility.  Concrete provides a safe secure environment for our children during the school day and can be utilized as emergency shelters in times of natural disaster or crisis.  The mass effect of the concrete allows the facility to economically maintain a steady temperature for human comfort that provides for maximum learning and greatly reduces the possibility of mold/mildew.  Tilt-up is the fastest form of construction from conception to completion which prevents long term disruption on the campus.

Harris 1500™ System Tested to Withstand 2,500 PSF!

A.H. Harris recently completed extensive laboratory testing of its Harris 1500™ System at the world renowned testing facility in Bethlehem, PA. The Harris 1500™ System was tested to 2,500 PSF without any permanent deformation of the system. 

The placement pressure test (photo 1.1) was conducted on a 5 million pound Baldwin-Lima Hamilton universal testing machine. A pressure bladder was used to apply pressure loading to the form panel surfaces, simulating in-situ pressure applied by fluid concrete during placement. The machine cross-head was lowered to approximately 6 inches from the form panel. Then a pressure bladder was inserted between the form surface and the machine cross head and slowly inflated to apply pressure to the assembly. 

Load cells (photo 1.2) and displacement sensors were installed to measure the response of the panel assemblies during testing. All sensors were connected to a Campbell Scientific CR5000 digital data acquisition system.  The CR5000 employs 16-bit analog-to-digital conversion. Data were recorded at a constant rate of 1 sample per second for the duration of each test. The tests were conducted numerous times with an ultimate pressure of 3,000 PSF.

The Harris 1500™ System is manufactured in the United States of America with skilled craftsmen and state of the art robotics. The system is laboratory tested and supports 1500 PSF. It is the best clamp system available in the United States, made with pride, Harris Pride!
