Colorado based UDR Inc, called upon Terra-Petra environment engineering in 2011 to work with the Bernards (a UDR contractor) in-house design team on Pacific Park, a $135-million shopping center and residential (mixed-use) development in Huntington Beach, California. At the onset, Bernards was faced with an unusual challenge; how to embrace the city’s proud identity as "Surf City" without descending into surfing kitsch. Terra-Petra was tasked to make sure that challenge was met, and it was.

Details about the status of this project has been reported on Terra-Petra's web and other media sites over the years, including the “a Terra-Petra photographic journal” of the Phase I Borrow Soils excavation for the Pacific City project in 2014 – courtesy of David L. Lucero. Terra-Petra is extremely proud of this project and what this development has become today.

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.

4 DEVELOPMENTS THAT WILL TRANSFORM FIGUEROA
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. So we decided to take a look at some of the developments that will reshape the future of one of Downtown's most notable streets:

1. Circa
Location: 1200 Figueroa Players: Hankey Investment, Jamison Services, Falcon California Investments, Highlands Capital, Harley Ellis Devereaux, LendLease. Completion date: Late 2017. The $500M project will build twin 35-story towers housing 648 luxury condos on top of a seven-story retail podium. There will also be 48k SF of retail and 1,770 parking spaces. This project broke ground in summer 2015 and features a curved glass look that offers a panoramic view of LA, and many other neighboring high-rises, including the Metropolis. Bisnow chatted with Hankey president Scott Dobbins this week to get the latest status update on the development.

2. Oceanwide Plaza
Location: Figueroa and 11th Players: Oceanwide Real Estate Group. Completion date: 2018, condos hit the market in 2017. Breaking 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 total. Chinese firm Oceanwide had previously acquired the development from New York City-based Moinian Group. This will be the first real estate venture for Oceanwide outside China.

3. Shenzhen Hazens
Location: Entire block bounded by Figueroa, 11th Street, Flower Street and Olympic Boulevard Players: Shenzhen Hazens, Gensler Completion date: After 2020. It's no secret Chinese firms are transforming the LA landscape. Shenzhen Hazens will add to the mix with a $700M redevelopment in the Luxe Hotel area. The project plans to break ground in 2017 and will be split into two phases. Phase 1 would build two 30-story towers, one residential and one hotel. 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. Promising to make it easier for transit and bicycle users, this project will start in late spring 2016 and complete in 2017 under a $20M budget. It will link USC and Exposition Park to Downtown LA with better signals, signage, crosswalks, transit platforms, bikeways and trees. There will be on-street, fully separated bike lanes on each side of Figueroa for 27 signalized intersections. There will also be a lot more accommodations for public transit, including for the Silver Line and the upcoming streetcar service.

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.

Advertised as being for “individuals new-and not so new-to brownfield redevelopment," the workshop provided an interactive series of presentations, panels, and case studies. Both Justin and Nate found that the CCLR seminar did a great job of living up to its billing. There was a diverse group of professionals from many different levels in the redevelopment process including governing agencies, developers, environmental engineers and environmental attorneys in attendence.

According to Justin Conaway: "In the environmental construction and engineering industry there is always something new to learn and we acquired valuable information by attending this seminar. CCLR did a great job as the sponsor and host of this event. The speakers were very knowledgeable and experienced. They all provided great insight into the brownfields management process. The seminar was well attended and the audience was engaged throughout the event."
