All backing for accessories, grab bars, heavy items 2. **Framing for Recessed Items** - Fire extinguisher cabinets, display cases 3. **Electrical Rough-In** - Hand dryers, motorized screens, digital signage 4. **Operable Partition Headers** - Structural support verification ### After Drywall, Before Paint 1. Recessed cabinet frames 2. Entrance mat frames 3. Verify all blocking locations ### After Paint 1. Toilet partitions 2. Toilet accessories 3. Lockers and shelving 4. Fire extinguisher cabinets 5. Wall protection 6. Visual display boards 7. Most signage ### Final Phase 1. Operable partitions (after all finishes complete) 2. Final signage installation 3. Fire extinguisher installation 4. Final adjustments and punch list ## Related Skills - **interior-finishes-trades** - Drywall coordination, blocking, finish sequencing - **doors-frames-hardware** - Door protection, hardware coordination - **fire-protection-systems** - Fire extinguisher requirements - **electrical-systems** - Power for dryers, motorized screens, digital signage - **quality-control-closeout** - Punch list and final inspection - **procore-project-management** - Submittal tracking - **construction-safety-management** - General safety requirements ## Common Issues and Solutions ### Toilet Partitions | Issue | Cause | Solution | |-------|-------|----------| | Doors don't close properly | Floor not level, pilasters out of plumb | Check floor flatness, adjust pilasters and hardware | | Grab bar mounting failed | No blocking installed | Install blocking before drywall; use toggle bolts as last resort | | Partition rust at edges | Wrong material for wet area | Specify solid plastic or phenolic for wet areas | ### Accessories | Issue | Cause | Solution | |-------|-------|----------| | Accessories pulling from wall | No blocking, poor anchors | Verify blocking pre-drywall; use proper anchors | | ADA non-compliance | Wrong heights/locations | Reference ADA mounting requirements; verify layout | | Hand dryer electrical issues | Circuit undersized | Verify dedicated circuit and voltage requirements | ### Operable Partitions | Issue | Cause | Solution | |-------|-------|----------| | Panels don't seal properly | Floor/ceiling not flat, structure deflection | Check tolerances; adjust seals; verify structural support | | Poor acoustics | Flanking paths, inadequate seals | Address ceiling plenum, verify seal engagement | | Difficult operation | Track alignment, dirty track | Clean and align track; adjust panels | ### Signage | Issue | Cause | Solution | |-------|-------|----------| | ADA non-compliance | Wrong character size, no Braille, wrong location | Review ADA requirements; relocate to latch side | | Exit signs not illuminated | Power issue, lamp failure | Check circuit; replace lamps/LEDs | | Wayfinding confusing | Poor design, inconsistent | Engage signage consultant; create standards |
