Methane Mitigation System Design completed for Child Development Center in Los Angeles
Terra-Petra recently completed Design Development plans of the Methane Mitigation System for the Temple Beth AM Early Childhood Development Center in Los Angeles. Terra-Petra has been working with the project architect, Pica+Sullivan Architects, to design the below grade methane and waterproofing systems.
The difficulties in working on this project revolve around the site being classified as a Methane Zone Property as well as having a shallow ground water table. The proposed structure will have a 1 Level Below Grade parking garage with a presumed ground water elevation a few feet above the finished floor slab. The Architect decided not to provide a permanent dewatering system for the building, but will instead provide a design that will allow the building to resist hydrostatic pressures.
With the existing Methane Code does not specifically address such designs, Terra-Petra has had a lot of experience in dealing with similar projects (i.e. Cedars Sinai Medical Center Advanced Health Science Pavilion) and coordinated with the entire design team (Architects, Structural Engineers, MEP/Shoring/Dewatering Contractors) to design and specify an all-in-one methane and waterproofing system to meet the code requirements and project needs.
Although the Terra-Petra system design does need some special handling with the Los Angeles Department of Building and Safety it’s a responsibility we were more than happy to take on for our client.
The membrane system that we specified includes both City of Los Angeles Research Reports for waterproofing and methane in one membrane. Our design has also been coordinated with the membrane manufacturer to make sure that it meets all the right waterproofing warranty requirements.
