Reorganized ACI 318-14 Provides a Modern Code Platform

Figure 1 Fins and offsets can be the result of form leakage. But fins and offsets have tolerances as described in ACI 117 and ACI 301. Fins and offsets are allowed but the height of each is controlled by the tolerances. If form leakage were prevented, there should be no tolerances. The fact that the tolerances are included in both ACI 117 and ACI 347 means that form leakage is acceptable but is limited by these ACI documents.

Formwork Mortar Leakage

A concrete contractor recently had a close-out meeting with the Owner and Construction Manager, and was be surprised by the demand for a reduction in payment based on form leakage.

The penetrations required in this depressed area in an elevated floor slab make it difficult to use 10-foot straightedges and riding power trowels. Specifiers should consider these multiple obstructions to finishing operations when determining F-number values. In this case, the specifier required F-numbers in the small depressed floated area that was to receive ceramic tile for bathrooms.

The Limitations of F-Number Specifications

Contractors need to be cognizant of certain situations that make it difficult to achieve routine FF and FL requirements and know how to get those specifications changed to more reasonable requirements.
