Vapors from Fuels, Oils, and Solvents Can Cause Negative Health Impacts and Sometimes Pose Safety Hazards. Vapor intrusion into buildings was first identified in the 1980s as concerns over radon gas intrusion grew. Since then, there has been an increasing concern that vapor-forming petroleum hydrocarbons and chlorinated solvents could threaten indoor air quality and human […]
An essential but hidden challenge facing owners and operators of facilities that have insulated piping or other insulated equipment is preventing or remediating corrosion of the metal surfaces under the insulation. Corrosion under insulation (CUI) is a recurrent problem for owners and operators of facilities such as power plants, commercial buildings, educational campuses, or any […]
Before the widespread use of drones, facade inspections and roof inspections were performed by climbing the exterior wall or dropping down a scaffold from the top of a building.

When moisture penetrates the building envelope during construction or occupancy, it can cause extensive damage. Many times, water penetration is due to faulty installation, improper construction, or the use of unsuitable materials. Ultimately, the design team is responsible for having the expertise and knowledge to create construction design documents that reflect a properly waterproofed building. […]
While the effects of improper water testing may have received the most media attention this year, the lack of other kinds of testing may also be a contributing factor to numerous environmental and regulatory compliance issues. Water contamination problems have continuously dominated headlines in cities like Flint and Kalamazoo, Michigan. In addition, this year Florida […]
