Daniel Valdez holds successful DMBI training seminar in Terra-Petra’s Los Angeles Office

Terra-Petra's Director of Field Operations Daniel Valdez Inspector training seminarTerra-Petra's Director of Field Operations, Daniel Valdez, held a Deputy Methane Barrier Inspector training seminar in our Los Angeles office this past week. He is responsible for overseeing the largest Deputy Methane Barrier Inspection (DMBI) team in the industry–as the Terra-Petra DMBI team continues to grow.  Daniel believes that it is imperative to periodically go over inspector responsibilities, requirements and reporting protocols to ensure that the information stays fresh in every inspector's mind and that Terra-Petra maintains continuity across the company.

IMG_20140430_163553_993Valdez is also a big proponent of staying in touch with the material manufacturers to ensure that his team members are certified to perform their work, keep up to speed with changing technologies, warranty requirements, what approved applicators are out there and inspection and reporting procedures. 

To that end he was able to schedule an inspector's certification webinar on the CETCO Hydroshield Warranty system to follow his presentation. The webinar was a refresher for most of the inspectors on the Terra-Petra DMBI team, who have inspected several projects under the Hydroshield program. Five new inspectors are set to receive certification for the first time.

The seminar was a success and there is no one more qualified than Mr. Daniel Valdez to have given the presentation.

Terra-Petra named methane design engineer and subterranean waterproofing consultant for Korean Air Wilshire Grand project

Wilshire Grand Hotel Los Angeles - AC MARTINTerra-Petra is proud to announce its role as the methane mitigation design engineer and subterranean waterproofing consultant for what will be the tallest building west of the Mississippi, the Korean Air Wilshire Grand project. Once completed, this 73 story skyscraper will top out at 1,100 feet tall and offer 5 levels of subterranean parking below grade. Earlier this year, Terra-Petra contracted with the prestigious architectural design firm of AC Martin Partners to prepare the methane mitigation and waterproofing system construction documents.

Terra-Petra had a very tight window in which to complete our design work, given the discovery of the methane mitigation design requirement only weeks before the foundation only permits were to be pulled. Fortunately, due to the strong capabilities of the Terra-Petra design team, we were able to deliver the necessary drawings on time in order to ennsure the project remained on schedule with no delays.

On November 21, 2013, Terra-Petra attended a pre-construction meeting, with Turner Construction, to discuss the installation of the methane mitigation/waterproofing system for the project (which is scheduled to start in December). Terra-Petra will also be performing the Deputy Methane Barrier Inspection (DMBI) work for the duration of this project.

“It's not every day that you get to say you had a hand in designing the tallest building west of the Mississippi. I am very appreciative of the opportunity that AC Martin has given Terra-Petra to be a part of this prestigious project. You never want to start behind the 8 ball and have to design to an extremely expedited schedule as we had on this project, but we did it! I feel that the work Terra-Petra has carried out is a testament to who we are as a company; knowledgeable, responsive, dedicated and really good at what we do. Needless to say I am very proud of my team," said Justin Conaway, Terra-Petra's Vice President and General Manager. 

According to the Wilshre Grand Center's website: “Starting in 2012, the property at the site of the former Wilshire Grand Hotel will be cleared to make way for a visionary new hotel and mixed-use building. Under the leadership of Korean Air, the developer of the project, the new building will revitalize the property and allow the site to continue being the indelible landmark it has always been. Doors will open to L.A. and the world in 2017, building upon the Wilshire Grand’s rich history." 

Additional highlights: 

  • This innovative project will be a completely new and unique experience in Los Angeles’ downtown. When the doors open in 2017, the project will be one of the most advanced, sophisticated, sustainable and unique buildings in Southern California.
  • With a unique “sky lobby” offering unparalleled views of the city and a breathtaking infinity pool, the building will rise 73 stories in the air as Los Angeles’ second tallest building.
  • 900 state-of-the-art hotel rooms, which will be operated by a flagship luxury hotel brand, will set a new standard for hospitality in Los Angeles.
  • 400,000 square feet of Class ‘A’ office space will attract high-end business leaders and make the building a global engine for business.
  • 45,100 square feet of new restaurant and retail space housing world-class restaurants will make this an epicurean delight and drive downtown’s food and cultural renaissance.
  • Pedestrian friendly access to downtown, as well as local and regional transit connections, will make the project a central and easily accessed location for visitors and Angelenos.
  • Innovative outdoor space and exterior plazas will invite guests and visitors to experience the true Los Angeles lifestyle and climate

Terra-Petera Methane begins mitigation system installation project for The Irvine Company in Playa Vista, California

Terra-Petra is excited to announce that the methane mitigation system installation is in progress on three new apartment complexes in Playa Vista being developed by The Irvine Company.

The Irvine Company selected the architectural firm of McLarand Vasquez Emsiek & Partners (MVE) out of Irvine to realize their vision of bringing a premier apartment community to the west side of Los Angeles. MVE has designed three mediterranean style apartment complexes each having one level of subterranean parking with on grade parking and four levels of apartments above grade. The building footprints increase in size moving from west to east from 187,067 SQ.FT., 256,866 SQ.FT. and 333,827 SQ.FT. 

MVE’s design team for these three projects included the following prestigious firms:

Structural Engineer: Englekirk –  Los Angeles
Civil Engineer: Fuscoe – Irvine
Geotechnical Engineer: Group Delta – Torrance

The project are located in the City of Los Angeles Methane Zone, thus Terra-Petra was selected by The Irvine Company as the methane design engineer for these projects given our strong Terra-Petra personnel witnessing the installation of Treco Barrier Solutions Vapor Lock-M. Left to right Andrew Alvarran, Jesus Mora, Danile Valdez and Eduardo Rangelreputation as a high quality methane consulting firm as well as our ability to simultaneously design three large scale complex projects in an expedited fashion. We were brought on to the design team in February of this year. We completed the methane mitigation system design work along with all permitted systems by the beginning of October, and way ahead of schedule.

The construction phase of this development began under Western National, serving as the General Contractor on the project. All three buildings are being constructed concurrently and Terra-Petra will be responsible for carrying-out all Deputy Methane Barrier (DMBI) inspection work for each one. The arduous task associated with performing continuous inspections of the methane mitigation system for three projects being constructed simultaneously can only be achieved by Terra-Petra given that we maintain the largest and most experienced staff of DMBI Inspectors in the industry.  

We're looking forward to completing another successful methane mitigation project!

INSPECTION UPDATE: 4661 W. Wilshire Blvd. Methane Zone Property

Terra-Petra is serving as the Deputy Methane Barrier (DMBI) and Waterproofing inspector for the Wilshire Condominium project at 4661 W. Wilshire Blvd. The condominium project was designed by Archeon Group Architects and is being constructed by Becker General Contractors, Inc.

Terra-Petra’s Daniel Valdez (Inspection Supervisor) is onsite today conducting a tutorial for the Terra-Petra office staff to bring them up to speed on the nuances of the Vapor Lock-M system, one of the many approved methane barrier membranes in the City of Los Angeles.

Terra-Petra is a big proponent of cross training our staff to provide them with an appreciation and understanding for each field of work that we can handle. This approach has proven to be invaluable in our success as a company as all staff members have a better grasp of each person’s roll with the company.

We've found that the guys are very supportive of one another and tend to “pull together" to finish projects and ensure a high quality work product for our clients.
