What is the solution? Understand the #1 reason the flooring contractor will walk off the job at the eleventh hour. The construction process, as it relates to slab flatness, does not work for the concrete pourer or the flooring contractor. Section 03-54-16 'Hydraulic Cement Underlayment', is conspicuously missing when it is needed just before the floor installation is scheduled so that slab creep, curl and deflection (sag) can be properly addressed as a billable extra prior to flooring installation. With this done the floor covering manufactures spec of 3/16" over 10' can be met. This disconnect between the concrete trade (Division 3) and floor covering trade (Division 9) ensures the opposite and results in delays, onsite and court room battles, failed flooring and clients left with second rate products.

Having an unbiased, independent, not-for-profit resource that all building parties (construction manager, design authority, floor covering installer, building owner) can refer to for best practices and industry recognized standards, is one way to get the right instructions agreed to in advance and included in the construction documents. It benefits all to have everyone on the same page, understanding their scope of work, pricing, bidding, scheduling accordingly and subsequently working better together. Where possible, NFCA is working with each of the construction groups to be that resource and support industry accepted practices for the floor covering installation portion of a build, just one small, but problematic, component of a much bigger construction picture.
