Detec Systems visited Terra-Petra’s Los Angeles office this week to conduct a comprehensive education and training session to promote their innovative product line of leak detection technologies. Detec provides leading-edge technology in the field of electronic leak detection (ELD), by way of membrane integrity testing and scanning, and automated structure monitoring. The training session included a classroom like session followed by field training on a jobsite.


The Terra-Petra Waterproofing Division is certified to conduct ELD testing throughout Southern California for numerous types of fluid-applied waterproofing and roofing systems in compliance with ASTM 7877-14. This includes any thermoplastic roofing system, any asphalt based waterproofing, traffic coatings, hot and cold fluid applied membranes and some bentonite systems (as long as they have thermoplastic reinforcement).

Terra-Petra employs the use of the Detec Systems Roof Membrane Integrity Scanner (RMIS) to accurately identify breaches in new and existing membrane systems. Many contractors are using a 24-48 hour flood test to check for breaches in these types of waterproofing assemblies. While this method can identify water leaks, it is time consuming and less cost effective. The benefits of the RMIS technology is that breaches and other imperfections can be identified, repaired and re-tested the same day, saving valuable time, resources and money for any project.

Terra-Petra performs subterranean waterproofing inspections for new Academy Museum project

Terra-Petra heads environmental engineering and waterproofing design, inspection and systems for the new $300-Million Academy Museum project at Wilshire and Fairfax Avenue which is slated to complete in 2018. 

June 14, 2016 for Urbanize.LA.

Even June Gloom failed to put a damper on construction at the LACMA campus on the Miracle Mile, where the Academy of Motion Picture Arts and Sciences' (AMPAS) long-awaited museum is well underway.

The $300-million undertaking, located at Wilshire Boulevard and Fairfax Avenue, will create a showcase for AMPAS' vast collection of filmmaking artifacts, including tens of thousands of still photographs, screenplays, production and costume design drawings, manuscripts and storyboards.  These assets will be displayed through a series of galleries, exhibition spaces, educational spaces and on-site theaters.

The museum, designed by the famed Italian architect Renzo Piano, will restore the May Company Wilshire department store, a Streamline Moderne structure built  in 1938.  North of the historic building, the project will add an eye-catching spherical glass structure, replacing a surface parking lot and a 1946 annex to the department store.

Completion of the Academy Museum is expected in Spring 2018.

Terra-Petra Environmental Engineering Helps Developer with Pico Gateway Apartments Project Success

Terra-Petra designed the environmental engineering designs and waterproofing systems for this multifamily property in the Pico-Robertson neighborhood just sold for $22.4M a few years back. As always, Terra-Petra is quite proud to be a part of the revision and revamping of land that was up until today, unusable. The revitalization of the LA Basin continues with environmental engineering being a key component of developers' success stories. So now, in what is becoming to be known as an increasingly popular Westside area, this building is being described as a “very high-quality property in a great location." 

This Week's LA Deal Sheet

The fully occupied Pico Gateway Apartments location offers 48,275 SF of rentable space, including 7,500 SF of ground-floor retail, 39 apartments and more than 135 underground parking spaces. Just two blocks from Beverly Hills, which is also a draw, apartment amenities include double sinks for preparing kosher meals, maple hardwood floors, double-paned windows to block out street noise and appliances. 

There is also an optional Shabbat elevator for residents to use on the Jewish Sabbath. Projected growth in the area is making the neighborhood increasingly popular. A recent study shows the population on the Westside could grow by 3.4% over the next five years.

Terra-Petra contributes to new projects transforming Downtown LA

As one of the most well-known environmental engineering and building waterproofing companies in the Los Angeles basin, Terra-Petra is currently working on or has completed some very high-profile projects in the Downtown LA area. Some of the most notable projects, among many others, include:

The Wilshire Grand Tower – the Wilshire Grand skyscraper will one day be the tallest west of Chicago. (Terra-Petra photo of project start to the right.)

The Metropolis, a $1B development is one of the largest mixed-use projects under construction on the West Coast.

Oceanwide Plaza will break ground in spring 2015. This $1B project will have a total of three towers and an expansive above-ground outdoor space. A five star hotel and 200k SF of commercial space will be included. There will be 504 condos and 183 hotel rooms.

South Park Mega-Project (Chinese developer Shenzhen Hazens) is a three towers along Figueroa Street across from L.A. Live. A 30-story hotel tower would rise at the northwest corner of Flower and Eleventh streets. A 30-story condo tower would be at Figueroa and Eleventh streets, and a 42-story condo tower would be at Figueroa and Olympic.

According to the Los Angeles Department of Building and Safety (LADBS), the "flurry of activity" in the recent years is defiantly the biggest construction boom they have witnessed since the 1980s.

However, LADBS does say that it is yet to be seen if it's the biggest boom in history or not. 

Stay tuned.

Los Angeles Mixed-Use Jan 14, 2016 Jerry Liu, Bisnow, LA

We already told you about some of the mega-projects that will reshape Sunset Boulevard, perhaps one of the most famous thoroughfares in the world. But if you're really following what's hot in LA, it's all about Downtown.

Phase 2 would completely replace the Luxe Hotel with a 42-story residential tower. Expect the finished mega-project to have 650 luxury condos, 250 hotel rooms and 80k SF of retail space. We caught up with Shenzhen Hazens Group executive project director Sonnet Hui recently to get more on the company's plans.

4. MyFigueroa
Location: Four miles of streets from Downtown LA to South LA. Players: LADOT, Troller Mayer Associates, Melendrez, GEHL Architects. Completion date: 2017.

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.
