RECo Awarded 1.5 Million SF – North Tarrant Express Design-Build

RECo has been awarded the design and supply of the Reinforced Earth Retaining walls totaling over 1.5 million square feet for The North Tarrant Express (NTE) design build project. This land mark award is the largest in RECo’s history and also includes more than 100,000 linear feet of precast topouts. The precast panels, copings and half connectors will be cast in RECo’s manufacturing facility in Waco, TX.

NTE consists of a series of major highway improvements to the critical I-820 and SH-121/183 (Airport Freeway) corridor between I-35 West and Industrial Boulevard in North Tarrant County. The NTE will relieve congestion, improve safety and provide for anticipated traffic growth in one of the country’s fastest developing regions. Construction is expected to start in late 2010 and is on fast track for completion by 2015.

Geomega MSE Walls - Los Vaqueros Reservoir

The Los Vaqueros Expansion follows the new era approach to project formulation by emphasizing environmental water management uses, as well as, municipal water supply reliability and quality. The expansion project includes 4 MSE walls totaling approximately 3,700 sm. Since the structures will be exposed to aggressive backfill conditions the walls will be designed using the Geomega system. The project site is within a relatively high seismicity zone which relates to a design acceleration coefficient of 0.5g.The MSE structures will be utilized to widen the roadway at the crest of the dam on the upstream side. Sections of the walls will be subjected to submerged conditions with 1m of rapid drawdown of the water level. Another unique feature of the project is the trapezoidal distribution of the reinforcement lengths (shorter at the bottom of the wall and increasing in length as the elevation of the wall increases) to minimize cutting into the existing dam.

The primary objectives of the Los Vaqueros Expansion is to develop water supplies for environmental water management that supports fish protection, habitat management, and other environmental water needs. As well as increase water supply reliability for water providers within the San Francisco Bay Area, to help meet municipal and industrial water demands during drought periods and emergencies or to address shortages due to regulatory and environmental restrictions.

MD Intercounty Connector - Contract A - Oppened to Traffic

The MD Intercounty Connector or otherwise known as The ICC, Contract A opened to traffic on February 23, 2011. The ICC will link the I-270 corridor with the Georgia Avenue Corridor - just north of Washington, DC. When the four remaining contracts are completed, the ICC will provide a link between the I-270/I-370 corridor with the I-95/US1 corridor.

RECo took part in the design and supply of MSE walls for several bridge abutments and retaining walls for Contract A, which required various custom form liner finishes. The Design Build Team of Intercounty Constructors, a joint venture of Granite Construction Company, Corman Construction, Inc., and G.A. & F.C. Wagman, Inc, Parsons and Jacobs designed and built Contract A utilizing Reinforced Earth rectangular panels, custom precast coping units and Terratrel temporary wire face MSE walls.
