Lateral System for Mid-Rise Construction
SpeedShaft™ is a prefabricated, stay-in-place, concrete wall formwork system that is engineered for mid-rise cold-formed steel construction. Delivered as panelized wall assemblies, each unit is precision-built with cold-formed steel and includes factory-installed reinforcing steel, reducing field labor, accelerating installation, and ensuring consistent quality.
Once installed, SpeedShaft walls serve as the primary vertical elements of the building’s lateral force-resisting system (shear walls) to provide strength, reliability, and code-compliant performance. By seamlessly integrating structural performance with offsite prefabrication, SpeedShaft streamlines construction, shortens schedules, and delivers a fully integrated lateral system.
01
Accelerated Schedule
Installation takes place concurrently with elevated floor framing. Eliminating the need to "top out" shafts before vertical construction continues.
02
Concrete Efficiency
Designed for same-day placement with slab-on-metal deck pours.
03
Predictable Production
Reinforcing steel is pre-installed in the factory, reducing field labor, layout risk and on-site materials and handling. The panelized system allows repeatable installation and reduced variability.
04
No-Ledge Shaft Condition
Simplify compliance and elevator inspection conflicts. The smooth linear plank finish makes a cleaner substrate for guide rail and component installation.
05
Aesthetic Finish
A clean architectural finish makes this system suitable for exposed interior shaft conditions, by eliminating rough cast-in-place wall finishes and providing a linear plank appearance on exposed surfaces.
06
Integrated System
Expect integrated structural components such as built-in deck support angles, guardrail system, and coordination with slab and framing system.
07
Labor Reduction
The wall panel crew will install the lateral system, eliminating a trade. No separate formwork contractor is required on CFS framing levels which reduces coordination issues.
08
Improved Jobsite Safety
Removes sequencing bottlenecks that can delay floor framing progress, by reducing the stacking of trades within the same vertical zone.
09
Reduced Crane Demand
No formwork or masonry stacking; fewer lifts and less hook time.
10
2-Hour Fire Rating
Code-compliant assembly without additional build-up
11
Eliminates Vertical Trade Stacking
No crews working above framing levels or above one another, reducing fall risk and falling object exposure. Creates a safer environment for field personnel and inspectors with more controlled and predictable work zones.
