The InQuik superstructure can be simply supported on bearings, or fully internal since it’s cast-in-place.

During construction of an integral bridge, concrete is placed in the abutment first, up to the seat, leaving part of the reinforcing cage exposed above the seat.

The superstructure panels are installed onto the seat, so the rebar in both the abutment and superstructure are tied together onsite, connecting the reinforcing.

The concrete is placed in the superstructure and deck, creating a monolithic concrete slab with the abutment.

This results in a very strong, stable and durable structure, providing greater resistance to flooding and earthquakes. It also eliminates the need for bearings and tie-downs, and the associated maintenance requirements for the life of the structure.

In addition to the standard InQuik bridge components, we can also provide custom design features at additional cost.

The deck formwork is a permanent fixture and remains in place, providing a protective barrier for the concrete against corrosive influences from the environment that can cause concrete degradation. 

There are three options for the deck formwork cladding: Weathering Steel, ZAM, and Stainless Steel, which each have different corrosion behavior. The most suitable cladding component would be selected based on its corrosion performance in each bridges’ specific environment. Other materials would require a special order.

The InQuik deck panels have been designed to satisfy the load rating criteria for HL-93 (AASHTO LFRD 9th Edition) bridge design specifications.

The simply-supported deck design is 0.3-0.5t heavier than the integral design.

InQuik prefers to work with standard designs where possible to optimize the design and manufacturing processes. However, bridges do have variable site specific needs, and so we offer non-standard premium features as well. If a project requires any features or dimensions not listed below, we may be able to provide for them in the design as well.

The InQuik abutment length is determined by the width of the bridge. 

The abutment height (to the deck shelf) is determined by the site conditions. 

The size and type of foundation drives the pile openings in the abutment.

Standard InQuik bridges have a flat side (no curb) or a castellated curb. Standard curb design is 6″ high, with a width of 8″.

Custom designs requiring a different curb can be accommodated if required. For multi-span bridges, the positive camber in the deck panel can result in a humped curb appearance, so we recommend installing a precast curb for multi-span bridges instead of the prefabricated InQuik curb.

Appropriate fixings and connections for barriers can also be included in the deck design, with a standard barrier design available for side and top-mounted low performance barriers.

The InQuik system is certified for low, regular, and medium performance barriers, and can accommodate a customized connection system as required.

Standard InQuik bridges include low performance Thrie-beam or regular performance TMR-style barrier.

Note: All galvanized components such as barrier posts and Thrie-beams must be stored correctly when they are received on site to prevent the formation of white rust. They need to be kept dry and clean, and positioned to allow any water which does accumulate on them to run off.
