Phoenix’s commercial leasing market — the volume of TI activity in the Phoenix metro. F&S’s experience with City of Phoenix and Maricopa County inspection processes on commercial TI projects. Named project types: restaurants (grease trap penetrations, kitchen walls), medical (lead-lined walls, clean rooms), retail, offices. We coordinate directly with GCs and architects to ensure masonry scope is on schedule.

Masonry TI Work That Passes Inspection and Keeps Your Buildout on Schedule

Why masonry and concrete TI work must be done to code the first time — re-work on a TI project delays every subsequent trade, extends the lease start date, and creates cost overruns. A demising wall that’s built wrong, a structural opening that’s sized incorrectly, or a slab penetration in the wrong location all stop the project. Father & Son Masonry coordinates with the architect’s drawings and the general contractor’s schedule to ensure masonry work integrates seamlessly with mechanical, electrical, and other trades.

Demising walls built to fire-rating specifications — UL-listed assemblies for required ratings (typically 2-hour), proper penetration sealing, inspection coordination with the AHJ.
Structural openings per engineered drawings — headers and lintels sized for the opening width and load, not rule-of-thumb. Lintel support and bearing confirmed before wall closure.
Slab saw cutting and core drilling for new penetrations — utility openings located precisely before cutting to avoid rebar damage. Work scheduled to coordinate with mechanical and electrical rough-in phases.
Work sequenced for multi-trade coordination — masonry complete when mechanical and electrical need access, not creating a bottleneck. Schedule communicated to GC weekly.

Frequently Asked Questions About Masonry Services

Common masonry TI work includes demising walls (the walls separating tenant spaces from other tenants or common areas), interior partition walls, structural modifications for new doorways or windows, and slab penetrations for mechanical/electrical/plumbing. Fire-rating requirements depend on the occupancy type and code. Father & Son Masonry handles all of these scopes.
For a typical 5,000-10,000 square foot tenant space with demising walls and some structural modifications, masonry work typically takes 2-4 weeks depending on complexity. The work is scheduled early in the TI sequence so mechanical and electrical can access wall spaces during rough-in. We provide a detailed schedule during the estimate phase.
Fire rating requirements depend on the occupancy type and code section. Most commercial demising walls between tenant spaces require a 2-hour fire rating. Walls between occupied spaces and mechanical rooms may require 1-hour. The architect specifies fire rating on the TI plans. Father & Son Masonry builds to the specified UL assembly.
Yes. TI permits are separate from the base building permit. The TI permit application includes floor plans, structural modifications if any, fire-rating assembly details for demising walls, and mechanical/electrical penetration locations. Father & Son Masonry coordinates with the GC on permit applications and handles inspection coordination.
Yes, absolutely. We work as a masonry subcontractor on GC-led TI projects regularly. We coordinate directly with the GC, work to the master schedule, and provide weekly schedule updates. We're experienced with multiple-trade coordination and understand the critical-path nature of commercial TI work.
