As part of Nevada’s Southern US 95 and US 93 Landscape and Aesthetics Master Plan for the Nevada State Highway System, gateway welcome signs are being installed by the Nevada Department of Transportation (NDOT), utilizing materials, colors and landscaping to coincide with the surrounding aesthetics.
Delta was contracted by Universal Precast Concrete, Inc. to provide design computations for the cast-in-place (CIP) footing, as well as the (20 feet by 8 feet) segmental precast monument. The monument is a gateway welcome sign located along the northbound Interstate 11 (U.S. Highway 93), near the Arizona border and just past the Hoover Dam Bridge. Other services included a reinforcement summary, connection details and stamped engineering drawings.
The CIP (13 feet by 8 feet 6 inches) concrete plinth features eight-precast concrete segments at 4,500 psi, designed to AASHTO LRFD 8th edition, color-pigmented to reflect the natural surroundings and designed with a (6 feet 10 inch by 10 feet 1 inch) inset state silhouette to accept the blue Nevada crest.
The segments, (weighing a total of 60,000 pounds) were cast with two large vertical voids then dry-stacked, threading each segment over vertical rebar projecting from the footing. The segment voids were grouted two at a time to tie the pieces together, using internal vibration for grout compaction.
The monument will welcome visitors day and night as it contains a Photo-voltaic panel (PV), providing continual energy-efficient lighting.
Universal Precast Concrete, Inc. is the only Western Region Precast Manufacturer to be certified by the Precast/Pre-stressed Concrete Institute (PCI), the National Precast Concrete Association (NPCA), and CalTrans (California Department of Transportation, Office of Structural Materials).
For 25+ years we have provided large- and small-scale, affordable, sustainable architectural precast, utility products, and site furnishings. We have enjoyed steady growth and have completed hundreds of projects with contractors, universities, cities, and counties, as well as state and federal clients.
While we continue to offer many standard precast items including concrete picnic tables, benches, bollards, and other site furnishings, our niche has become the design and manufacture of custom precast items. We have an in-house design team that creates designs from photographs, renderings and other conceptual materials.
Our state-of-the art facility is located in Redding, California, where we create some of the most unique custom concrete products using CAD systems, molds and finishes.
We provide on time delivery, custom designs, and offer builders and developers an excellent one-stop shop.
Universal Precast Concrete offers a large variety of both standard and custom precast concrete products. Our technology allows us to make almost any item per customers’ specifications—there is really no limit to the variety of products we make. Many times contractors come to us with "cast in place" items that are just too difficult to make in the field. Our specialized, rapid molding technologies allow us to create those difficult and tricky items in a controlled environment ensuring the highest quality for the end product.
