PROGRAM MANAGER: Nick Kacsandi, M.S.
OPPORTUNITY: Technology licensing, product acquisition, contract research, proof of concept leading to scale-up to manufacturing, joint development, supplier agreement
Phase 1 - Initial conversations under NDA (Q3 2015)
Phase 2 - Proof of concept, Sample testing, etc. (6-12 months)
Phase 3 - Commercial scaling / Supply agreement (by Q4 2016)
To be determined based on the nature and scope of the proposed technology. Development and optimization funding up to $250K may be available, depending on the ability to match Year 1 ROI requirements (up to 50,000 splices). At commercial scale, anticipated volumes may exceed 2.5M splices annually.
SOLUTION PROVIDER HELP DESK:
NineSigma, representing a leading supplier of non-residential construction products, invites proposals for technologies capable of achieving a tension and compression splice that prevents failure in reinforcing rebar to a distance of two (2) bar diameters from the connection point.
In most structural applications, the steel rebar cages that provide necessary reinforcement are comprised of dozens or hundreds of individual connection points. Regulatory requirements (e.g. California CT270, etc.) dictate that in a failure scenario these connection points – or splices – between individual rebar components cannot be the ultimate failure point, and must be able to survive cyclic tension and compression loads. Furthermore, the point of failure must occur remotely from the connection, at least two (2) bar diameters from the end of the splice.
A variety of innovative approaches are currently employed to address this requirement, including clamping or compression mechanisms, threaded connections, lap splicing, and grout-filled sleeve fittings. However, the current solutions are not universally applicable due to variability in the installation requirements from application to application. The RFP sponsor seeks potential partners with novel approaches or technologies that can create a universally reliable connection that supersedes the strength of the structural rebar in the end application. Approaches that promote similar performance and failure characteristics at the rebar-end anchor connection point (as opposed to the rebar-rebar connection) are also of significant interest.
Solutions are invited from across the landscape of industry, research and academia. Of specific interest are those cross-industrial technologies that can be reapplied from similar applications involving connections of other steel components, non-ferrous metal components, high strength composites and other materials.
Anticipated Project Phases or Project Plan
Phase 1 – Initial discussions under NDA to determine validity of approach
Phase 2 – Proof of technical concept against RFP specifications
Phase 3 – Commercial development
The successful technology will:
The final qualification testing for the strength and efficacy of any proposed solution following proof of concept must meet the client’s requirements as a free-standing system without the benefit of being embedded in concrete.
