How are these certified? Can you design to meet my state's DOT requirements?
The InQuik Bridge meets AASHTO LRFD Bridge Design Specifications, 9th Edition, and CMC is engaged with state DOT's to ensure state design compliance and enable the use of both federal and state funding for installation.
Where do you manufacture?
We have a manufacturing facility in Georgia. We can easily ship by truck (up to 3 deck panels can stack on top of each other) with no extra transportation permits required.
What are the lead times?
Currently, CMC Bridge Systems lead times are 10-12 weeks, which includes final design steps.
What does the system include?
InQuik offers a full solution above the foundation, including abutments, wing walls, super-structure, and pier/bent caps if necessary. Our superstructure panels are also available in simply-supported configurations compatible with existing abutments. And our abutments are compatible with all bridge foundation types.
What is the design life?
Our bridges are certified to meet AASHTO Load and Resistance Factor Design (LRFD) Bridge Design Specifications, with a 75-year design life. Contact us to discuss specific service life design requirements for your project.
How long will your bridge uphold under heavy salting?
Our bridges are designed with enhanced corrosion resistance targeting a minimum service life of 75+ years. We utilize continuously hot-dipped galvanizing (ASTM A1094, GalvaBar®) as standard. Longer service life requirements can also be met and must take into consideration site-specific parameters. Contact us to discuss your project’s service life needs.
What types of formwork are offered?
ZAM (zinc, aluminum, & magnesium) is the most common, but we also offer weathering and stainless steel, with each having different corrosion behavior. The most suitable formwork should be selected based on its corrosion performance in each bridge's specific environment.
What type of rebar do you use?
The standard for our bridges is CMC's GalvaBar, a galvanized rebar with a zinc alloy coating that provides the well-known corrosion protection of zinc that can be galvanized, then fabricated, without peeling or flaking.
How does InQuik reduce whole of life costs?
The InQuik integral design combines enhanced corrosion protection with integral abutments to eliminate bearings, tie downs, bolted connections, and longitudinal joints, ensuring minimized structural maintenance over the entire service life.
Are the bearings part of the bridge?
While InQuik deck panels can be simply-supported on elastomeric bearings, our integral design eliminates the need for bearings, further reducing long-term maintenance.
What is an integral bridge? How does an integral design work?
An integral bridge is one that has structural continuity between the deck and abutments that support it. This fully continuous connection between the superstructure and substructure at the abutments eliminates the need for joints or bearings to accommodate rotations and thermally-induced displacements at the ends of the deck. As the deck and abutment components are filled with concrete on-site, this creates a more robust structure with reduced service life maintenance requirements.
Are there any traffic volume limits on the bridge?
The structure is designed to current AASHTO LRFD Bridge Design Specifications. Larger traffic volumes can be accommodated through modular design approaches that easily allow wider decks with more travel lanes.
Do you install it?
We do not perform the installation, but we do provide an on-site support representative throughout the entire process and installation, and are happy to collaborate with/provide consultation to any contractors, engineers, or crews as needed.
How long does it take to install an InQuik Bridge?
The time to install depends on the time to strength of preferred concrete mix used, the complexity of the bridge design, and the speed and preferences of the installer. For example, it is possible to install the abutments with wing walls and pour and finish the concrete in one day. In general, the set-and-assemble methodology means that a typical InQuik bridge can be installed in 5-7 days over a total project timeline of about 1-2 weeks.
How many components can be transported on one truck?
A typical single lane, single span bridge can be transported on one truck, which includes 2 deck panels, 2 abutments with wing walls and the appropriate connection pieces. It is possible to transport 3 standard deck panels stacked on one truck. Singular abutments and deck panels have previously been transported with a standard pick-up truck, with no need for transportation permits.
How do I learn to install an InQuik Bridge? Do I need certifications or transportation permits?
We provide detailed installation guides and a full set of stamped construction drawings upon request, and we also provide an on-site representative for each installation. No certifications or transportation permits are required.
Do I need a crane to install it? How heavy is the average pick?
Many of our components can be set with an excavator. The average pick is about 3-5 tons. A small crane can be used for our larger spans, with the heaviest picks ranging from 12-15 tons.
How do you install a multi-span bridge?
The InQuik system is versatile and can be used for various structures, including single-span and
multi-span bridges. Multi-span bridges can be fully integral or simply-supported with decks tied down to the pier/bent cap using brackets. InQuik's custom pier caps support these configurations, allowing for flexible and durable bridge solutions.
Does it require any temporary shoring?
The abutments and bridge deck are fully self-supporting, and do not require any external shoring at any point in the construction process.
Do I need a specific type of concrete? Can I use accelerated concrete?
We recommend that you use your local ready mix concrete, with a 5,000 psi strength and 3/4" max aggregate mix. High performance mixes are fully compatible with the InQuik Bridge System as well.
How do you fill the structure with concrete? Can I pour in one go? A single pour?
The abutments can be set and filled on the same day, pouring in roughly 20" lifts and vibrating adequately. After the abutments have been cured to minimum required strength, the deck panels can then be set, spliced and filled. For spans longer than 45 ft, deck panels need to be poured in two stages, with the deck beams poured and cured to 3,500 psi first, then followed by the final deck pour.
After the concrete is poured, how long until it can take traffic?
Both the abutment and the deck are designed to use 5,000 psi concrete. Unrestricted traffic is allowed after the deck concrete reaches design strength.
Do you need any post-tensioning?
The set and pour assembly process does not require post-tensioning for the final constructed state or engineering capacity.
How do you install the barrier system? What types of barrier systems can be installed?
The InQuik system is certified for TL-2, TL-3, and TL-4 barriers, and can accommodate a customized connection system, as required. The deck modules can accommodate all barrier types, including top/side mounted, steel barriers, and concrete barriers. The anchoring bolts are pre-assembled in the fabrication shop, and contractors can then install in the field.
Do you design the foundation? What drawings do you provide?
CMC provides a signed and sealed structural design only. Site-specific design elements related to hydraulics, foundations, alignments, etc., are performed by the owner or owner's design consultant.
Is there a specific foundation needed?
InQuik bridges are compatible with all major bridge foundation types. The best foundation for a particular bridge will depend on site-specific conditions. Pile pockets are detailed into the InQuik System abutments at standardized spacings, which depend on the foundation type used in the site-specific design. Compacted gravel beds can be used below the abutments, but most commonly a thin concrete blinding layer is used to facilitate construction.
What vehicle loads can be designed for?
Our bridges are compliant with AASHTO LRFD's Bridge Design Specification HL-93 live load. They are also designed to meet state-specific design vehicles and permit vehicles, as necessary.
What are your span lengths? Is this adjustable?
Our span lengths approximately range from 21'-61', with increments at 21', 30', 40', 45', 53',and 61', with a 3' shorter clear span difference for each size (please refer to drawings for exact measurements). Multi-span bridges can be used for longer bridge lengths.
What widths can you accommodate for?
Bridge widths are flexible and customizable. The modularity of the InQuik Bridge System allows for additive width design. Deck modules are 8-ft wide and we also offer spacer plates (sheets of formwork that are spliced) up to 22" between deck modules for further customization.
Do superstructure deck panels depths vary?
Our deck panel depths, measured from top of wearing surface to bottom of girders, range from approximately 15" for our 21' span, 28" for our 30', 40', and 45' spans, 36” for the 53’ spans, and 40" for the 61' spans. The standard deck thickness is 8" with a 2 1/2" cover over the top mat.
What abutment dimensions are available?
We offer two abutment depths, 3' or 4' deep based on need for an approach slab. The standard height begins at 3'-11" (increasing in height in 8" increments). You can have a maximum height of 8' (for abutments with a single concrete pour). For abutments taller than 8’, a thicker blinding slab can be used, or we can provide segmented abutments that are spliced in the field and filled in two concrete stages. If an approach slab is required, an integral approach slab detail can be incorporated into the backwall design.
What are the measurements and angles for your wing walls?
Wing walls are approximately 6' to 9' long, with angle options of 45 or 90 degrees.
Can you accommodate for skews?
Yes, our standard design can accommodate for up to a 30 degree skew.
