Concrete Masonry Field Tolerances Webinar

A discussion of TMS 602 tolerances


The Mason Contractors Association of America (MCAA) will present “Concrete Masonry Field Tolerances” on Wednesday, May 9, 2018 at 10:00 AM CDT, sponsored by J. Construction Company.

Variations always exist between specified dimensions, and locations, and their as-built counterparts. TMS 602, Specification for Masonry Structures, gives tolerances for these variations intended to maintain life safety and assure structural performance.

Join Darrell McMillian as he discusses TMS 602 tolerances including: receiving foundations, unit and mortar assemblies, steel reinforcement placement, and relationship of tolerances to the project quality assurance plan.

Mason contractors registered for Masonry Certification will receive 1.00 credits in the Codes & Standards discipline upon completion of this course.
