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.

Los Angeles, CA (PRWEB) December 24, 2013

Los Angeles Environmental Engineering firm Terra-Petra was named 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.

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 the design work, given the discovery of the methane mitigation design requirement only weeks before the foundation only permits were to be pulled. Due to the strong capabilities of its design team, Terra-Petra delivered the necessary drawings on time to ensure 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 is also the Deputy Methane Barrier Inspector (DMBI) or the City of Los Angeles 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,” said Justin Conaway, Terra-Petra's Vice President and General Manager. “The work Terra-Petra has carried out is a testament to who we are: knowledgeable, responsive, dedicated and really good at what we do. Needless to say I am very proud of my team.”

In 2012 the property at the site of the former Wilshire Grand Hotel was 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 Los Angeles and the rest of the world in 2017, building upon the Wilshire Grand’s rich history. For more information, visit: http://www.wilshiregrandcenter.com.
