Terra-Petra Environmental Engineering Recognized in the LA Times as part of Wilshire Grand project - tallest skyscraper in the West.

Terra-Petra Team recognized in the LA Times as part of the Wilshire Grand project – the tallest structure in the west and the Los Angeles skyline.

The Wilshire Grand project grew from a handshake to become the tallest building west of the Mississippi. For three years, Times staff writer Thomas Curwen has chronicled its construction, from the initial planning phase to the topping off and final design touches. One the pages, are his stories of the Wilshire Grand tower.

To express his appreciation to all those who were involved with the Wilshire Grand project, Korean Air & Hanjin Group (property owner) Chairman Yang Ho Cho, placed the multiple-page advertisement in the Los Angeles Times  on June 27, 2017. He wanted to  publish the name of every person who worked on the project.

Working closely with A.C. Martin and Turner Construction on Los Angeles’ newest and tallest skyscraper, the Terra-Petra team is proud to be recognized in this LA Times piece (attached/linked PDF) above. 

The Trojan Marching Band headlined the special Ribbon Cutting Ceremony on the Plaza area to celebrate the Grand Opening of the Wilshire Grand Center (June 23rd). The media covered event was hosted by Korean Air & Hanjin Group. Chairman (and USC alum) Cho and his team also hosted a private party in the building that evening.

Below are a few highlights we grabbed during the grand opening ceremony—along with fresh photos of, what Chairman Cho describes as, “the crown jewel of Figueroa Street.” Again, Terra-Petra is proud to be recognized as part of this outstanding project.

The Use of Electronic Leak Detection (ELD) on Waterproofing Membranes over Concrete Surfaces

Waterproofing membranes are a key element in building enclosure systems—a key element that ultimately gets covered up by a variety of finish materials including landscaping, green roofs, topping slabs, pavers and so on. As most of us know, excavation to expose a failed waterproofing membrane for repairs can be prohibitively expensive and in some cases impossible. For this reason, many designers are choosing to specify integrity testing to verify that the waterproofing membrane is free of discontinuities and penetrations through the membrane prior to the installation being permanently covered. When integrity testing is not specified, many contractors are often performing this type of testing voluntarily to avoid future problems or “call-backs.”

The most common integrity testing method is the flood test. Flood testing is typically performed by flooding waterproofed horizontal surfaces with at least two inches (50 mm) of water for a period of up to 48 hours. Temporary dams are often constructed to partition the test areas, provide an up-turned plaza edge and control the depth of the flood testing. During the flood test, access to the underside of the flooded areas is necessary for a visual inspection of water leakage. However, in the case of a membrane failure (leak), flood testing indicates only where water is penetrating through the entire assembly within the test area, not the location above where water is breaching the membrane. In addition, flood testing cannot be performed on vertical surfaces or at locations where the underside of the slab is not accessible.

The aforementioned restrictions and lack of conclusive data associated with flood testing has enabled Electronic Leak Detection (ELD) to gain momentum as a viable alternative to traditional flood testing. This article will focus on the different types of ELD and the applications where ELD is or is not well-suited.

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.
