Methane Mitigation Design – Torat Hiyam

Level II Methane Mitigation Design

Terra-Petra has just closed  with Torat Hiyam to provide methane mitigation design for their new project in Los Angeles, CA.

The new construction will consist of a 5 story school building, with a basketball court and a library.

The scope of work will include a Level II methane mitigation design plan with permitting to be approved by LADBS Mechanical Department Plan Check.

Methane Soil Gas Investigation In Los Angeles

Terra-Petra has submitted a bid to Data Specialties to conduct a methane soil gas investigation on a LADBS Methane Buffer Zone Property on in Los Angeles, CA.  The proposed project will consist of an electrical upgrade, with no new building construction.

The scope of work includes shallow and deep boring at the site, and monitoring methane gas concentrations and pressure on consecutive days in order to prepare an LADBS Certificate of Compliance for Methane Test Data.

Abandoned Oil Well Leak Test – Redondo Beach, CA

ABANDONED OIL WELL CONSULTATION, INSPECTION AND TESTING

Terra-Petra was recently hired to by the developer of a Redondo Beach property to consult on all California Department of Conservation, Geologic Energy Management Division (CalGEM) requirements associated with the potential discovery of an old abandoned oil well on their property.

Historical records and photos identified the oil well within the property boundaries, however, previous efforts to locate the well by the developer proved fruitless.

Once engaged by the client Terra-Petra employed our standard process for well locations which we call our “oil well due diligence”.

STEP 1 - Geophysical Survey

The first step in the process is to conduct a geophysical survey of the site. Oil Wells can be identified by the magnetic anomaly that shows up when conducting this work given that their casings are usually constructed of steel. Steel cased oil Wells have a specific “signature” that is very distinct from other metallic objects such as buried pipe or equipment. It becomes very apparent in the mapping system when an oil well is present.

STEP 2 - Oil Well Excavation

The second stage of the process is to physically locate the well by excavating and uncovering it. We inspect the integrity of the casing and the surface plug (if present). Once this is done, we notify the local CalGEM representative that we have located a well and that we will be conducting the leak testing.

STEP 3 - Oil Well Leak Test

We then conduct a leak test at the well casing to identify if any fugitive gasses are emanating from the casing. The precise location of the oil well is then surveyed in by our survey crew and plotted on a site plan per CalGEM’s standards.

STEP 4 - Final Inspection & Client Summary Report

All information from our activities are compiled into a summary report and provided to the client for distribution to the appropriate agencies.

Methane Soil Gas Investigation – Methane Buffer Zone

Methane Soil Gas Investigation (SGI)

Grace Partnership, Inc has on-boarded Terra-Petra to conduct a City of Los Angeles Methane Soil Gas Investigation (SGI) in Los Angeles. The property falls within a Methane Buffer Zone.

Terra-Petra recently completed the site assessment and sampling in accordance with LADBS guidelines under Terra-Petra’s LADBS Methane Testing Lab License #10224.

We are in the process of drafting the Summary of Methane Soil Gas Investigation report and will be delivering it to the client shortly.

Methane Mitigation And Gas Detection System Design, City of Los Angeles

Terra-Petra wrapped up a City of Los Angeles Methane Mitigation and Gas Detection System Design for a Level 5 methane site for Welcome Projects of Los Angeles, CA. Terra-Petra provided design consultation for the new ground up single-family Accessory Dwelling Unit (ADU) as well as the addition to the existing home.

How Terra-Petra is addressing Covid-19

We are open and operating.

Many of you have heard the announcements from the Governor and local LA county officials regarding “safer at home” mandates. Based on a review of the orders and applicable exemptions, Terra-Petra is continuing to operate under the Essential Business category.

As we continue to operate, however, we will comply with all pertinent requirements of the orders.

As an engineering firm that works with contractors and other engineers on critical projects, we also fall into the “Necessary Services” category, along with the various other disciplines of engineering.

The majority of the work that we take on includes municipality, public works, affordable housing, and critical transportation projects.

Our waterproofing division also falls into this category, as our team is in a position to keep properties safe by resolving issues that could ultimately lead to health concerns such as mold and mildew spores, along with other health irritants impacting a person’s well-being.

We will continue to work diligently with our clients to provide safe working conditions on-site for all of our people. We also want to stress the importance of all of our people practicing proper safeguards that have been published, such as washing hands frequently, keep hands away from the face, using hand sanitizer as frequently as possible, and practicing proper “social distancing” while on-site with other people, if required to attend any meetings (on or off-site).

Please be safe, and feel free to report any concerning issues to management with respect to job site conditions, practices, activities, or anything that you feel is not conforming to health guidelines during these challenging times.  Contact us if you should have questions or a need at hand.

Sincerely,

Kevin Buchanan

Terra-Petra Attends 18th Annual Brownfield Training Conference in LA

In 1996, a cross-section of stakeholders came together in Pittsburgh for the very first federally co-sponsored National Brownfields Training ConferenceTerra-Petra’s environmental project team took part as an exhibitor at this 18th annual event, December 10-13, 2019, at the Los Angeles Convention Center.

Cosponsored by the U.S. Environmental Protection Agency (EPA) and the International City/County Management Association (ICMA), the National Brownfields Training Conference is the largest gathering of stakeholders focused on cleaning up and reusing formerly utilized commercial and industrial properties.

The heart of Brownfields 2019 is a dynamic educational program of speakers, discussions, mobile workshops, films and other learning formats that are calibrated to provide case study examples, program updates, and useful strategies for meeting brownfield challenges head-on.

Featuring dozens of educational sessions and mobile workshops including many showcasing the City of Angels and the redevelopment in the surrounding region, the exceptional training offered by the conference has something for both beginners and seasoned professionals.

The conference is also a premier stop for the private sector with a vibrant exhibit hall and other transactional activities that are catered towards companies doing the business of brownfields cleanup and redevelopment. The exhibit hall featured federal agencies, engineering firms, and environmental cleanup companies (i.e. Terra-Petra), as well as legal and financial expertise, nonprofits, and other types of organizations.

How L.A.’s museum district is rebuilding.

Terra-Petra is proud to be part of the 5411 Wilshire, a planned $400 million apartment and retail complex at 5411 Wilshire Blvd. in the historical Miracle Mile district of Los Angeles, led by Walter N. Marks Inc. (developer) and Keating Architecture.  A recent Los Angeles article covers the exciting and much needed changes along the famous Wilshire Blvd. supporting the immediate community and the 5411 Wilshire project.

L.A.’s museum district is rebuilding. But they’re ignoring pedestrians (again)

However, we are not certain  about how the changes will affect pedestrians in a negative way. In fact the changes we have taken part in will only benefit those who visit or frequent the Miracle Mile!
