EFCO is proud to partner with Granite Construction on the Addicks & Barker Dam project.
PLATE GIRDER panels were used to form the abutment footings, abutment stem, wing walls, pier cap, 7′ x 9′ x 47′ (2.1 m x 2.7 m x 14.3 m) tall piers, 47′ (14.3 m) tall arch support piers, and pier walls. One of the distinguishing features on this project is the pier caps with radial soffits, which went up to 51′ (15.5 m) long x 14′-4″ (4.4 m) deep x 7′ (2.1 m) wide and required a custom soffit form. The custom 7′ (2.1 m) radial soffit allowed the contractor to minimize the labor that would have been required for the wood build-up. EFCO also worked with Tutor Perini management during the design phase to minimize the amount of formwork and to have efficient re-use of equipment. Minimizing labor and a good concrete finish were important features throughout the project.
Retractable Stripping Corner is a Time Saver!
Middlesex elected to use the EFCO PLATE GIRDER® wall forming system with the Retractable Stripping Corner, a recent addition to EFCO’s product line. In a matter of minutes, Middlesex was able to strip the inside box using only one worker and fly it to the ground for cleaning and oiling in a single crane pick.
SUPER STUD JUMP SYSTEM
Site Superintendent, Joe Luis, and his crew fully adhered to the project schedule with a seven-day cycle time for each core. Because of the large abundance of wall plates on the outside faces of the cores, Middlesex elected to set the outside forms first and utilize a full perimeter SUPER STUD® jump system to accommodate wind bracing and access. A Flipper Lock access platform was provided inside the core for tying the reinforcement, which was also easily removed during the installation of pre-cast stairs.
Road bridges are getting longer, wider, and heavier. This construction is being supported with stronger available concrete and stronger reinforcing steel, all weighing more. EFCO’s new product, SUPER PLATE GIRDER, now available has twice the strength of EFCO’s very successful original PLATE GIRDER.

Construction of New Office Building
EFCO E-Z DECK® shoring earned an opportunity to step in to help Crain Concrete Construction develop a solution for the Bank of the Ozarks new office headquarters. A tight timeline to deliver the parking garage prior to the construction of the office building meant that EFCO needed to design, engineer and deliver in short order. Engineering tackled the challenge of an intricate beam and slab geometry to design a shoring system that would cycle efficiently, while field service used operations worksheets with Crain’s foreman to set crew sizes for efficient cycling. EFCO’s team, along with the Crain team, worked in unison to meet the schedule to produce a great-looking structure while working safely and efficiently.
Over half of the 150+ interior bent caps poured on the project utilized the hinge soffit design.
El Paso, Texas
When completed, the Boarder West Expressway will provide an alternate route for I-10 on the west side of El Paso near the University of Texas El Paso (UTEP) and will address needed improvements to safely guide the region’s growth and development. The $500 million project, which broke ground in spring of 2015, is a joint venture with J.D. Abrams, L.P. and Kiewit Infrastructure South Co.

Shoring Needed for Deck
JEKS Engineering Sdn. Bhd. is the contractor for this project. The warehouse measuring approximately 1,140,000 ft2 (106,000 m2) will be mainly constructed using precast components including hollow core slabs, columns, beams, walls, dock levelers, planks, and staircases. However, shoring was required for the massive 150,700 ft2 (14,000 m2) cast-in-place deck for parking located on top of the warehouse, 85′ (26 m) above ground level.
Increase in productivity
EFCO supplied JEKS with 66,750 ft2 (6,200 m2) of EFCO E-Z DECK® for the construction of the parking area. Divided into nine “pour zones,” the largest of the areas at 16,700 ft2 (1,550 m2), averaged 7 to 10 days to complete one cycle. Unfamiliar at the beginning of the project with the E-Z DECK system, the JEKS crew quickly mastered the assembly and cycling processes and have increased their productivity. Over the course of the project, some zones changed dimensions requiring the crew to convert table arrangements of the E-Z DECK on the fly.
More Efficient Power Technology
The supercritical coal-fired power plant in Mauban, Quezon, Philippines under San Buenaventura Power, Ltd. Co. (SBPL), is a partnership between Meralco PowerGen Corp. (MGen) and New Growth BV, a subsidiary of the Electricity Generating Public Co., Ltd. or EGCO Group of Thailand. The power plant is said to be the first in the country to use state-of-the-art technology, which is more efficient than all other existing coal plants in the Philippines. The power plant will play a crucial role as electricity demand grows, especially in Luzon, which accounts for 70% of the country’s gross domestic product.

Unique Application – Hartford, Connecticut
Kenny Obayashi JV challenged EFCO to provide a rollback system on an inside radius application. Using the EFCO REDI-RADIUS® system mounted to EFCO’s GUIDED RAIL SYSTEM (GRS) frames provided the best value and lowest in-place concrete costs on the South Hartford Conveyance and Storage Tunnel.
EFCO engineers designed a solution that included two 12′ (3,600 mm) REDI-RADIUS forms mounted on three GRS frames to create 24′ (7.2 m) long gang forms. Custom GRS shoes were designed with a bevel to allow the outer frames to be parallel to the center frame that was using the standard GRS shoe. In addition, EFCO Combination Bias Corners and Reverse Bias Corners were installed between gangs and oriented so every other gang could be rolled back for cleaning first, then the other gangs could be rolled back immediately after. Forms were then rolled forward in reverse order.
No Ties: A Requirement
Project requirements also demanded the system be a tieless 74′ (22.6 m) diameter compression form x 10′ (3 m) tall placement. The contractor completed the 80′ deep shaft and shipped the forms back while they excavated another 100′ (30.5 m) down. At that point, the contractor requested EFCO’s assistance to reconfigure the forms to the next diameter of
Waller Creek Park, Austin Texas
The Waller Creek Conservancy and the City of Austin, through a Public Private Partnership (P3), awarded Zachry Construction Corporation the Waller Creek Park project as the Construction Manager at Risk
(CMAR). The project includes the restoration of Waller Creek from Waterloo Park to Lady Bird Lake. The project revitalizes and restores this area by creating a chain of parks and connecting the community with a pedestrian infrastructure of creek crossings, sidewalks and overlooks. Zachry will perform pre-construction services and eventually oversee all construction activities.
