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.

Advancements in Deep Foundations: Augered Cast-In-Place Piles
Located in downtown Fargo, North Dakota, the Block 9 Redevelopment project site contains highly-compressible soils in the upper 100 feet with groundwater about 10 to 15 feet below the existing ground surface. The owner prohibited using driven piles to avoid disturbing neighbors of the project and historically, drilled shafts are used in Fargo as a reduced noise and vibration alternative to driven piles. However, developments over the last 20 to 30 years in drilling equipment, load testing and integrity testing resulted in the project team identifying augered cast-in-place piles as a suitable alternative for this project. To reduce the risks...
