CAMP Monitoring

A Community Air Monitoring Plan (CAMP) reduces the potential for airborne contaminant releases from a project site and provides a measure of protection for communities downwind of contaminated sites. This is accomplished by establishing action levels in response to real-time monitoring for volatile organic compounds (VOC) and particulates (i.e., dust).

Concrete Shrinkage and Cracks

I had a college professor that said concrete was guaranteed to do two things…harden and crack. Hardened concrete is the result of hydration, a chemical reaction between cement and water. The loss of water from the concrete as it cures results in a reduction in concrete volume, or shrinkage.

Hot Weather Concrete

The American Concrete Institute (ACI) defines ‘Hot Weather’ as high ambient temperatures, high concrete temperatures, low relative humidity, high wind speed, solar radiation, or any combination that will impair the quality of concrete due to accelerated moisture loss and/or cement hydration. Most summer days in New York State would qualify as ‘Hot Weather’, using ACI’s definition.

PCB in Caulk

Polychlorinated biphenyls (PCB) are a group of manmade chemicals that were introduced in the 1930’s due to their chemical stability, non-flammability, high boiling point, and insulating properties.
