What Concrete Technology Corporation does

Concrete Technology Corporation (CTC), founded in 1951 in Tacoma, Washington, is a private precast and prestressed concrete manufacturer that designs, fabricates, and delivers structural components for public infrastructure and commercial construction. The company operates from a 30-acre single-site campus featuring over 150,000 square feet of enclosed casting beds, four high-capacity stressing beds (4.4-6.16 million kip capacity), a 150-ton overhead crane, and a unique 150' x 500' graving dock with 12-foot draft for assembling and launching large-scale floating concrete structures. CTC produces 27 distinct product lines spanning bridge girders (wide flange, decked bulb tee, I-girders, tub girders, box girders), building and parking garage components, marine products (fender piling, load-bearing piling, sheet piles, pile caps, haunched decks), floating structures, hollow core detention vaults, and miscellaneous heavy construction elements including tunnel liners and shore protection.

The company pioneered the use of prestressed concrete in the United States and developed girder sections — notably the Wide Flange and Decked Bulb Tee — that were adopted as standards by WSDOT and are now used across the continental U.S. and Alaska. CTC holds PCI certification in the most rigorous tiers (B4 and C4) and has been a WSDOT-approved fabricator since the early 1990s, gating most major bridge and transit work in the Pacific Northwest. Its customer base is heavily concentrated in government buyers, including WSDOT, Sound Transit, the U.S. Navy, U.S. Coast Guard, U.S. Army Corps of Engineers, ports of Tacoma and Seattle, and municipal agencies; private-sector clients include hospitals and automotive/retail (e.g., MultiCare Mary Bridge Children's, AutoNation BMW).

CTC generates revenue through project-based, quote-based contracts (no public pricing; revenue model is one-time project delivery rather than recurring license or subscription) sold via a direct sales force segmented by product line and delivered by truck, barge, or rail. The wholly-owned R&D subsidiary Concrete Technology Associates (CTA, est. 1973) and active participation in PCI/ACI technical committees support continuous technical advancement, evidenced by the 2019 national record 223' 4.5" WF100TDG girder and ongoing ENR, PCI, and AASHTO award recognition. CTC remains privately held, with no evidence of private equity or institutional investor involvement.

Products and services

• Wide-Flange Girders WSDOT's premier and preferred girder series for bridge jobs in Washington state. Many girder sections from 36 inches to 100 inches tall have been developed to accommodate a wide range of bridge spans. CTC played a key role in developing the Wide Flange Girder section, now adopted as the standard by WSDOT.
• I-Girders WSDOT I series girders — basic I girders that have been used longer than any other I girder in Washington state. These girders vary in depth from 42 inches up to 74 inches and can be used for spans between 40 feet and 160 feet.
• Tub Girders Tub Girders (Trapezoidal Girders) used in bridge and mass transit guideway structures. Single piece girders typically span 40 feet to 130 feet, or girders can be spliced to achieve a longer span.
• Box Girders Versatile product used for vehicle or pedestrian bridges, culvert replacements, and marine piers. Box Girders typically incorporate a styrofoam center to reduce piece weight while maintaining a robust look.
• Decked Bulb Tees Versatile long span girder that incorporates the benefits of both an I girder and a precast slab deck. Typically used for vehicle bridges, ranging from as small as 40 feet up to 160 feet. CTC developed the Decked Bulb Tee Girder section now widely used across the continental U.S. and Alaska.
• Voided Slabs Precast prestressed slabs for bridge, building, marine pier, and fish passage culvert replacement applications. Voided Slabs generally span 30 feet to 90 feet.
• Channel Beams Cost-effective solution for short to medium span structures. The top deck can be manufactured with a variety of traction profiles, eliminating the need for field applied wearing surfaces.
• Solid Slabs Fully customizable concrete slabs of varying width, length and thickness. Solid Slabs can be designed and produced with mild reinforcing or by adding prestressing strands.
• Wide Flange Decked Girders WSDOT WFDG and WFTDG series girders — the newest girder cross sections developed by Washington State. These versatile girders combine the longer span capacity of the WF girder with the reduced field work advantages of the Deck Bulb Tee girders.
• Double Tees Common precast flooring elements for larger projects. Parking garages frequently utilize this cost-effective solution to support vehicle loads on fewer columns to increase available parking stalls.
• Spandrels Play several roles in a parking structure including providing a pedestrian and vehicle barrier, performing as a beam to support floor members, and incorporating aesthetic design to enhance the structure.
• Columns Vertical members that support beams or spandrels and usually bear on a cast-in-place footing. Columns can be fabricated with or without supporting corbels depending upon connection design and number of floors.
• Beams Typically support floor or roof elements and bear upon columns or walls. They can be fabricated in many shapes and sizes such as Rectangular Beams, Inverted Tee Beams, L Beams, and Scissor Beams.
• Wall Panels Solid or insulated precast wall panels for partitions, cladding or load-bearing applications. Many finish options are available, such as reveals, formliner patterns and brick veneer inlays.
• Hollow Core Hollow Core slabs with a variety of uses, including floors and roofs for buildings and parking garages, decks for piers, and lagging for retaining walls. Proprietary methods developed through extensive internal testing push span lengths and load capacities beyond standard limits.
• Hollow Core Detention Vaults 12 1/2 inch thick Hollow Core slabs highly recommended for all detention vaults. Generally untopped and designed with a thicker top flange to provide greater durability and increased punch-through shear capacity for heavy traffic loading.
• Floating Structures Durable precast concrete floating structures for marine applications including breakwaters, berthing structures, and heavy-duty floating platforms. Both open-cell and foam-filled floats are produced. CTC has supplied over 30 large concrete floating structures for West Coast, Alaska, Hawaii, and Java Sea projects.
• Marina Floats Concrete marina floats for small to medium applications with inherent toughness and durability for harsh environments. CTC has an extensive history of marina float fabrication.
• Pile Caps Precast concrete pile caps providing a superior solution to cast-in-place concrete caps, delivering significant schedule acceleration for both bridge and fixed-pier structures.
• Load Bearing Piling Prestressed concrete piling produced for over six decades for marine piers and building foundations. Excellent resistance to bearing and bending loads, exceptional durability, and lower initial cost and long-term maintenance.
• Fender Piling Prestressed concrete fender piles — the material of choice for the protection of fixed pier structures and vessels during berthing and mooring activities, with high energy-absorption fendering capabilities.
• Sheet Piles Prestressed concrete sheet piles for continuous retaining wall applications. Interlock between sheet piles is provided with either a tongue and groove longitudinal keyway or adjacent grooves that are field-grouted.
• Haunched Decks Optimized for heavily loaded marine facilities and industrial structures. The haunched profile, end continuity and oversized shear keys provide an efficient method for resisting large, randomly placed concentrated loads on a deck.
• Shore Protection Concrete armor units — an economical alternative to natural rock for breakwater and shore protection applications. CTC has manufactured numerous types and sizes of concrete armor units ranging from 2.65 tons to 23 tons.
• Stadium Risers Precast concrete stadium risers providing durable seating solutions requiring little maintenance over their service life. Can be fabricated in single or multiple rise configurations and are suited for both indoor and outdoor seating.
• Tanks Precast tanks for storage of water, petroleum, sewage and dry-bulk goods. Constructed with curved wall segments that are internally post-tensioned after erection.
• Tunnel Liners Precast tunnel liners made to match the requirements of each tunnel. Installed immediately after the tunnel boring machine progresses and designed to resist earth pressure and groundwater head.
