2 CorTek is a stay-in-place modular form system, engineered to simplify and accelerate the construction of reinforced concrete stair and elevator core structures. Features: Factory built, high tolerance, steel construction Rapid, simplified erection procedure Erection of form system can be concurrent with erection of building framing Horizontal reinforcement steel installed at the factory* Rapid field installation of vertical reinforcement facilitated by guide fixtures* Stairs pre-installed at the factory, providing early trade access to building floors Form system is designed by CorTek to support limited construction loads prior to placement of concrete, typically self-weight of the framing member plus a 20 psf construction live load CorTek modules do not require stripping Corrugated steel surface can be left exposed or clad with almost any architectural material Available for forming cast-in-place reinforced concrete cores ranging in thickness from 8 to 12 Contact CorTek for LEED information *All reinforcement shall be designed and specified by the specifying professional Free up site schedule and resources by modularizing core form work off site in a specialized factory set up for quality and efficiency: Stay-in-place modular form system for concrete core structures Factory built modules stack like building blocks Custom-built to the specific requirements of each project Faster, Safer, Higher Quality and Cost Competitive: Framing does not wait for cores Immediate presence of stairs allows trades early and safe access to structure Elimination of many dangerous field operations Reduction of poor fit-up and coordination programs among trades Cost comparable to conventional cast concrete Please contact the CorTek Team for more information at CorTek@vulcraft.com. 1

3 CorTek Stay-in-Place Access Core Forming System Design Team Quick Reference The following is a quick reference for the building design team when specifying the CorTek Form System. The specifying professional(s) is responsible for producing drawings and specifications which define the requirements for the core walls and stairs in the final constructed form. The structural drawings or specifications should include: Elevations for all core walls, dimensioned for all geometry and annotated with reinforcement requirements (vertical and horizontal rebar sizing and spacing). Due to form construction, vertical bars must be spaced at 8 or 16 increments. Horizontal bars must be spaced at 4 increments. Details of all special reinforcing elements including headers and boundary elements (the design of these elements may require detailing coordination with CorTek, but is by the specifying professional). Nominal thickness of core walls. This is the design thickness required by the specifying professional for the shear wall design. Typical thicknesses would be 8, 10, and 12 nominally. Due to the 1 steel deck skins of the form system, walls will have an out-to-out dimension of 10, 12, and 14 respectively. Core elevations must define opening sizes and locations. Definition of the top of foundation walls supporting the core walls. Typically, a minimum of 6 below the top of the floor level slab so that the connection between the core wall and foundation wall is hidden below the top of slab. The preferred connection between core walls and foundation walls. CorTek can supply embed plates or form-savers to be installed by the foundation contractor at the top of the foundation. Final embed design will be performed by CorTek. All loads at the connection between the core walls and foundation walls. These loads are used to design the connection at the foundation. Loads must be broken down per load type. End reactions for all beams and other floor or roof members framing into the concrete core. These loads must represent the end reactions on the core during the occupied life of the building and must be broken down into their load types (i.e. dead load, live load, etc). All loads and deflection limits required for structural design of stairs and handrails The architectural drawings must include: Any geometry of the stair cores not defined by the structural drawings Stair layouts including rise, run, and plan dimensions. 2
