Mixed-use project, called Metropolis, is unprecedented for Downtown L.A.

If you travel down through the Downtown LA area on a regular basis, you have probably noticed the every-changing skyline. As an environmental engineering firm, Terra-Petra is taking part with many of these new projects. One of which is called the Metropolis (you can't miss this large mixed-use community steadily growing along the 110 freeway). The Terra-Petra Waterproofing Division is consulting on the building envelope waterproofing system for the Metropolis project and inspecting all of the waterproofing as it gets installed.

Terra-Petra working on eleven of top fifty construction projects in Los Angeles

Environmental engineering firm, Terra-Petra, is currently working with close to 42% of the top 50 construction projects in the Los Angeles area—as listed by the Los Angeles Business Journal in the publication’s new (2015) Book of Lists.

Los Angeles, CA (September 22, 2015) — Terra-Petra, a national environmental engineering headquartered in Downtown Los Angeles has announced that the firm is currenly working with 24% of the top 50 major construction projects currently underway in Los Angeles County—as listed on the Los Angeles Business Journal’s 2015 Book of Lists. This complete collection of data on industry leaders in a variety of industries was researched by the LABJ editorial team of the past year. The top construction projects have been ranked by construction cost and excludes infrastructure projects

According to Justin Conaway, Vice President of Terra-Petra. “Terra-Petra has been fortunate enough to have the diverse service offerings which have allowed us the opportunity to bid on a wide array of these developments. Our customer intimacy strategy allows us to offer a great value to our clients, I truly believe that our close customer/client relationships have differentiated us from our competition and has permitted us to secure many of these contracts.”

Terra-Petra’s involvement with most of the construction projects listed on LABJ’s Top 50 list ranges from methane testing, mitigation design and inspection to building envelope waterproofing consulting and inspection. “Hopefully our recent contributions will help to ensure that each project we work on is safe and successful,” says Kevin Buchanan, Terra-Petra President.

Working with 11 of the top 50 , Terra-Petra is currently supporting three of the top four ranked projects (number 1, 2 and 4) as well as with numbers 14, 16, 21, 25, 27, 41 and 47 and 50. Justin Conaway is also currently working on a bid with one other project on the LABJ list. Read the Top 50 Construction Projects in Los Angeles list here: Page 1, Page 2, Page 3.

“More realistically there are only 28 projects listed that are probably in a methane/methane buffer zone. So to be more accurate we are working on 42% of all potential projects on this list that we could bid on. That is a pretty impressive market share considering all of the local competition,” says Conaway.

Terra-Petra Managing Removal of Asbestos Containing Material in Downey, CA

Terra-Petra is serving as the environmental engineer of record for a large retain development in Downey, California. The project is well under construction and has included the demolition of some existing buildings and mass grading for the site.

During grading activities, the contractor had uncovered several old abandoned concrete encased pipes buried in the soil. Terra-Petra was called out to analyze the concrete for asbestos content and to manage the removal of the material as needed. 

Terra-Petra's Senior Project Scientist was able to mobilize to the site within 24 hours of the contractor reporting the discovery of potential ACM materials on the property. Within 48 hours, samples were collected and the results were received back from the lab stating: "the black felt/fibrous material showed negative for asbestos. The light-colored pipe encased in concrete showed positive for asbestos and will require special handling."

Terra-Petra is in the process of mobilizing its Industrial Hygienist to the site to manage the removal of the ACM per the local state and federal standards.

Historical Use of Asbestos
During World War II, use of Asbestos Containing Material (ACM) products peaked, and the shipbuilding industry utilized the mineral extensively. From the early 1900s to the 1970s, asbestos was the ideal material to use.

Why asbestos? Simple: It was cheap, durable, flexible and naturally acted as an insulating and fireproofing agent. The construction and manufacturing industries fell in love with its potential and used asbestos-containing products whenever possible.

Malignant mesothelioma, otherwise known as mesothelioma cancer, commonly develops in the lungs of people exposed to asbestos. Effective treatments are available to ease symptoms and improve your prognosis.

The cancer usually affects the thin, protective membrane surrounding the lungs, heart or abdominal cavity. Doctors diagnose an estimated 3,000 cases a year in the United States, and the majority of those are traced to job-related asbestos exposure.

Although asbestos use declined dramatically in recent decades in this country, the incidence of malignant mesothelioma remains steady. That difference can be traced to the distinct latency period linked to the cancer.

The disease can take anywhere from 20 to 50 years after exposure to asbestos before it shows obvious symptoms and an oncologist can make a definitive diagnosis.

While no cure for the disease exists and the prognosis is typically poor, researchers made significant progress in recent years in understanding the cancer and developing new treatment options and alternative therapies.

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.
