Vapor Intrusion Mitigation Design – Hayward, CA

Terra- Petra is pleased to continue partnering with a major property developer to provide Vapor Intrusion Mitigation System (VIMS) Design Assistance in Hayward, CA. The scope of work involves mitigation of VOCs that could pose a potential vapor intrusion concern into a future occupied structure at the site.

This includes document review, conducting a Human Health Risk Assessment (HHRA) and submission of a Basis of Design report complete with Construction Quality Control procedures and an Operation, Maintenance and Monitoring plan (OM&M).

The vapor intrusion mitigation system will be designed in accordance with the Alameda County Department of Environmental Health’s Local Oversight Program (ACDEH) and in general accordance with the Vapor Intrusion Mitigation Advisory published by the C.A. EPA Department of Toxic Substances Control (DTSC) dated October 2011 (Cal/EPA 2011a, 2011b).

Vapor Intrusion Mitigation System Design – Pomona, CA

Terra Petra is currently working with a client to provide full scope vapor intrusion mitigation system design (VIMS), inspection, and monitoring services for their development in Pomona, CA.

The proposed development will consist of two new slab on grade, 3-story multi-family affordable apartment buildings with a combined footprint of 26,330 SF.

Terra-Petra will work with the City of Pomona (permitting agency) and with The Los Angeles County Department of Public Works (LACoDPW), Environmental Programs Division (EPD) which prescribes means and methods of protecting structures from vapor intrusion.

Vapor Intrusion Mitigation System – Palo Alto, CA

Terra-Petra’s Environmental Engineering Division has partnered with a significant environmental consulting firm in the Bay Area to prepare a comprehensive Vapor Intrusion Mitigation System (VIMS) for a new development located in Palo Alto, CA.

Terra-Petra designed the passive mitigation system with the ability to convert it to an active system in the future if deemed necessary. The VIMS System was reviewed and approved by the Department of Toxic Substances Control (DTSC).

Having completed the VIMS design we have moved on to the construction administration phase which includes submittal review and RFI responses, as well as the QA/QC inspections. We are currently on-site overseeing the smoke testing of the subslab membrane system.

Terra-Petra to attend topping off celebration for 2747 Park project in Palo Alto

The Level 10 team is set to celebrate the topping out of the the 2747 Park project on Thursday, October 5th. Designed by  the Jay Paul Company, this development is steps from Caltrain in Palo Alto, California. 2747 Park provides a future-forward workplace designed for Silicon Valley’s innovative workforce. Terra-Petra has been invited to attend the event having designed the vapor intrusion mitigation system for the site. Level 10 will also have the topping out beam available for signatures onsite beginning October 3rd.

Terra-Petra’s GM/VP Justin Conaway to speak at the Colorado Environmental Management Society March 10

JustinConawayVPGM Terra-Petra GM/VPCEMS March Luncheon – Engineering Control Trends in Vapor Intrusion Mitigation – March 10

Speaker: Justin Conaway, Vice President |General Manager and Patrick Guan, Regional Manager, Terra-Petra Environmental Engineering.

Tuesday, March 10, 11:30am – 1:00pm.  There will be no CLE for this presentation.

In recent years the implementation of vapor intrusion mitigation systems has become more common for ground-up development. There are many different forces and factors that are influencing this rise in popularity. There are also numerous engineering controls available to protect a given building from vapor intrusion. This presentation discusses the Vapor Intrusion Mitigation Engineering Control Trends that are being specified and installed today on new construction projects. The benefits of these systems will be outlined and we will identify how various stakeholders have influenced the current trend.

Justin Conaway, VP/GM of Terra-Petra has been with the company since 2004. In this time he has developed a unique knowledge of the vapor intrusion industry in that he has been involved with nearly every aspect of the vapor intrusion cycle from site characterization through installation.

Mr. Conaway has a wealth of experience and competencies, including: Construction Quality Assurance Inspection, Mitigation System Design, Permitting, Document Submittal and Negotiations with Governing Agencies, Risk Management Decision Making Process with Developers, Contract Negotiation, Installation Costing, On-Going Operation and Maintenance Monitoring and Reporting, and Research and Development to launch innovative vapor intrusion products.

Patrick Guan, Regional Manager for Terra-Petra has been with the company since 2012. In this time, he applied his vast experience in sales/marketing, strategic planning, operational management, and superior customer service skills that he developed over the past 17 years working for fortune 500 companies to help drive the ambitious expansion goals of Terra-Petra from a regional success story to a thriving successful nationwide operation.
