Super•Cor’s performance, savings sway NSTIR off concrete spec

September 15, 2015


Nova Scotia Transportation and Infrastructure Renewal (NSTIR) had specified a concrete structure for a stream crossing on the new exit connector joining Highway 103 with Highway 3, at Ingramport, near Halifax. Knowing that our Super•Cor Arch would perform just as well and provide considerable savings, the AIL team went to work to prove their point.

A Value Engineered Alternative
To be successful on a design/build project like this, any solution other than the specified one has to meet the minimum requirements for an NSTIR Value Engineered Alternative (VEA). We met with their design office regarding a VEA with our Super•Cor Steel Arch with Vist-A-Wall headwalls. We indicated that both these solutions were already specified in the NSTIR General Specifications and they agreed to evaluate them as a VEA.

By selecting our efficient and easy-to-install VEA solution, the contractor and the owner were able to realize significant shared savings. Plus, the Super•Cor Arch was a more environmentally-friendly option, with higher recycled content and lower impact on the fish habitat.

We worked closely with the contractor to ensure the structures were completed according to schedule. Project follow-up confirmed that all went well through the complete project cycle.
