Water Intrusion Inspection – Ventura County Naval Base

Terra-Petra is currently working with Aetypic (AET) Architecture and Engineering to provide forensic waterproofing services at the Ventura County Naval Base in Point Mugu.

Terra-Petra is investigating historic water intrusion issues at the site. We are performing an A/E study to  include the review of window systems, of roofing parapet cap/roofing materials, and destructive testing of the exterior building envelope.

The AE study includes investigation and design development with recommendations for repairs.

Terra-Petra consults on newest LA Multifamily Developments to Implement Tetris-Style Parking System

Two new multifamily developments in Los Angeles are getting a unique Tetris-style semi-automated parking system that could lead to a shift in how residents park their vehicles. In late summer 2018, Beverly Hills-based Markwood Enterprises broke ground on a 14-unit, 16K SF multifamily property in mid-Wilshire and a 13-unit, 12K SF multifamily development in Larchmont. Each offers one unit for very-low-income tenants.

Terra-Petra provided environmental consulting pre- and during the ground breaking as well as waterproofing consulting  services for the  a two-level subterranean semi-automated puzzle shift parking system developed by CityLift.

“Every developer in LA knows if you can’t park it, you can’t build it,” Markwood Development Director Simon M. Aftalion said. “This enables us to pack in the density in a responsible way. Otherwise we wouldn’t be able to house this many units because we wouldn’t be able to park them.”

Multifamily developments in Los Angeles are required to have two parking spaces for each two-bedroom unit, one and a half spaces for one-bedroom units and one space for studios. But the innovative system by Oakland-based CityLift could start a trend in the city’s multifamily landscape that allows developers to build more density with less space, Aftalion said.

Dunsmuir Row, 1233 South Dunsmuir in mid-Wilshire will offer 18 parking spots, while the project, Elmwood Row, on 4807 Elmwood Ave. in Larchmont will have 16 parking spaces.

The puzzle shift — sometimes referred to as a puzzle lift — system appears as a stacked four-by-two grid. When a resident parks in a reserved spot, the system shifts or slides the vehicle or lifts it into place. The cars can be accessed independently. It takes an average of 30 seconds for a resident to retrieve a vehicle.     Read the entire article on Bisnow.com.

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.

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.

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.
