Consolidation of Trades

In today’s labor market, a reduced need for skilled workers is helpful to completing projects on time. Building with CELBLOX allows the consolidation of trades on the job site during construction. A crew of three ICF installers can accomplish what a crew of framers can accomplish in less time. CELBLOX performance wall systems combine six components into a single system that can be installed by one crew at the same time (concrete, steel rebar, insulation, air barrier, vapor barrier and furring). CELBLOX construction is compatible with carpenter trades and as a result, the scheduling and subsequent congestion caused by the use of a number of trades is unnecessary since one trade can easily accomplish the work needed.

Compared to construction with concrete masonry units, because the strength and weight of monolithic concrete is about twice that of CMU, CELBLOX ICF concrete walls typically replace red iron but are an additional cost when building with CMU’s. In addition, 2 ½ workmen are required for CMU compared to 1 workman for ICF construction. As a result, it typically takes three times longer to build a CMU wall as opposed to an CELBLOX ICF concrete wall adding labor expense.

With CMU walls, furring strips for interior drywall must be applied by a framer. Because CELBLOX include plastic furring strips every 8” on center within the form, the extra material and labor expense of CMU’s is unnecessary.
With a CMU wall an additional wall parallel to with a space between would need to be constructed with 5” continuous foam that does not allow air infiltration to the CMU wall in order to equal the insulation performance R-value of a CELBLOX ICF concrete wall.

A Cabela’s store was built using ICF’s rather than CMU construction. Using 2014 RS Means data, had the walls been built with CMU and finished to the same degree, the expected labor rate to build a wall assembly comparable to the ICF walls would have been .217 man-hours per square foot. On the actual job, the ICF construction crew recorded .109 man-hours of labor per square foot completing the walls in ½ the time traditionally required.*
