Mitigation of potential organic vapor migration into buildings has become a requirement in many states to protect occupants of buildings located near contaminated soil and groundwater, including Brownfield sites undergoing redevelopment. Complete the form to watch our free webinar where we will discuss design and operation of passive and active vapor mitigation sub-slab ventilation systems (SSVS). We will provide examples of system design and construction components and operating data for several existing systems located in the Minneapolis and Milwaukee metropolitan areas.

Structure Support On Laterally Swept Piles
Anyone who has observed a significant number of piles has seen that, inevitably, the pile is not perfectly straight after driving. In spite of the best efforts of contractors, there are a whole host of reasons for piles to end up out-of-plumb or to have a curve, sometimes referred to as pile sweep. For two, recent projects with numerous swept pile, the available research was determined to be limited in application given the investigated pile sizes, lengths and measured sweep. As a result, the project team chose to perform static load testing to evaluate the ultimate resistance of the swept...

Leveraging the Value of Geotechnical Engineering
Geotechnical engineers are civil engineering professionals who evaluate soil, bedrock, and groundwater to identify subsurface conditions that can potentially impact proposed development. Through continued engagement, a geotechnical engineer can bring additional value to projects by providing the designer with recommendations throughout the life of a project. Soil characteristics can heavily influence the development of construction projects. For that reason, a geotechnical evaluation should be part of the site assessment to reduce potential unidentified site conditions. A geotechnical evaluation is an investigation process that is often one of the first documents prepared for a project. The information gathered includes the footprint...
