Terra-Petra awarded contract to perform methane and water intrusion inspections for Northern California project

Terra-Petra was recently awarded the contract to perform inspections at the Maple Street Correctional Facility site in Redwood City, California. The Northern California site requires excavation below the water table and is located within a region impacted by naturally occurring methane gas. As such, the future building is susceptible to the impacts of methane gas and water intrusion and requires a dual methane barrier/waterproofing system. Gergen Construction is in the process of installing the system which will consist of a membrane and passive venting system to adequately protect the building.

The inspections will be administered through Terra-Petra’s San Francisco office. Terra-Petra’s Deputy Methane Barrier Inspectors (DMBI) come prepared with diverse certifications and extensive knowledge of prevalent systems, making Terra-Petra a versatile choice for any methane/water impacted construction project. The Maple Street Correctional Facility site is no exception. For this project, Terra-Petra’s certified Hydroshield, Coreflex and Liquid Boot inspectors led to the selection of Terra-Petra as the best team to get the job done.The joint effort and long-standing relationship between Terra-Petra and Gergen Construction will ensure an efficient and reliable system to provide the project owners with an environmentally safe building.

 

 

 

Terra-Petra Completes Methane Barrier and Below Grade Waterproofing Work on Cedars-Sinai’s Completed Advanced Health Sciences Pavilion Project

The new Cedars-Sinai Advanced Health Science Pavilion integrates clinical care and biomedical research in a single building. Terra-Petra Environmental Engineering developed the combination LADBS approved methane mitigation system as well as the buildings below grade waterproofing system for the 820,000 square foot structure.

According to Terra-Petra's VP/General Manager, Justin Conaway, "Terra-Petra performed all LADBS Deputy Methane Barrier Inspections (DMBI) for this project; we also provided manufacturer required below grade waterproofing system inspections to ensure the project received the full 15 year Hydro Shield warranty."

Terra-Petra Deputy Methane Barrier Inspectors are cross-trained, qualified and certified to perform the below grade waterproofing inspections in order to provide a substantial cost-savings by performing both of services with one inspector. Terra-Petra currently employs 7 LADBS Deputy Methane Barrier Inspectors (DMBI).

"We are proud to be a part of such an outstanding project and very excited for Cedars-Sinai Medical Center and their quest to provide services for today's new era of health care within the new Advanced Health Sciences Pavillion," said Kevin Buchanan, President of Terra-Petra.
