What's Needed to Comply?
Using probe assessment to determine Methane levels we can determine best plan of action for your job site. LADBS has provided a Methane Standard Plan which provides excellent guide lines to follow in the development of site specific plans. The site may fall in a range of Level I thru Level V. As the Methane levels increase so do the requirements needed to mitigate the dangers of methane intrusion.
Methane is extremely flammable when enclosed and concentrated. Otherwise it is odorless and colorless, and escapes naturally into the atmosphere. Although, there are areas in Southern California with naturally high methane concentrations (i.e.…LaBrea Tar Pits) Most high levels are found adjacent to land fills and/or abandon oil wells and fields.
Our focus is Methane mitigation, VOC mitigation and Below grade waterproofing. We work with the most prominent Methane Engineering Consultants in the Country giving us the upper hand to assist our clients from start to finish.
Most projects begin with straight forward probes of the soil. Probes are set at random locations at a variety of depths. They are then monitored to determine the level of soil gasses present at that time. Once the methane gas or other gas level is determined, the data is analyzed, and the level of hazard determined. From this data a methane mitigation plan can be designed.
A sound methane mitigation design will combine the data from the Hazardous Soil Gas Assessment report, with the building foundation plans, to develop a system to halt and extract any gas from threatening intrusion into the building. In addition to the basic design and building parameters, our designers pay close attention to the fiscal ramifications of the materials specified in the plan.
If your consultant cannot tell you the costs of installing, the system that they’ve just recommended to you on your development project, you’ve probably got the wrong guy! Ralph Ray Construction, Inc designs to a budget, while incorporating jurisdictional guidelines and specific site conditions.
