Site Inspection

A comprehensive on-site evaluation to identify potential sources of contamination, including above-ground and underground storage tanks, hazardous substances, and other environmental risks.

Interviews And Documentation Review

Discussions with current and past property owners, occupants, and local officials to gather valuable information about the site’s history and potential environmental concerns.

Report And Recommendations

A detailed report summarizing findings, identifying recognized environmental conditions (RECs), and providing recommendations for further action, if necessary.

How Terra-Petra is addressing Covid-19

March 20, 2020
Environmental Health, Terra-Petra Company News, Terra-Petra Leadership, Terra-Petra News

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
