SH concentration maintained at 1.5% — within LPS 7.4 §4.2 maximum 2.0% for EIFS surfaces. EIFS-Pro surfactant selected from LPS 7.4 Appendix C approved product list. Hot water unit limited to 150°F during EIFS contact per §3.8 temperature restriction. No high-pressure direct impingement on EIFS panels.
Pre-service checklist completed per Marriott PCM-2024 §6.1. Pool water chemistry unaffected (filter intake covered). Drain inlets blocked with portable berms rated for pool runoff per §6.3. Post-service surface pH verified neutral before pool deck reopened at 9:05 AM.
Porte cochère cordoned from 6:00 AM — hotel provided valet redirection signage and guest notice in app. Pool deck cleared per brand evacuation protocol (30-min advance notice via front desk). Wet floor signs (ANSI Z535.2) placed at 12 walkway entry points. Zero guest-contact incidents recorded.
Pre-service walkthrough with David Kowalski, Director of Engineering, at 7:55 AM. Scope confirmed, restricted zones documented. Front desk briefed at 8:00 AM. GM completion notification sent 11:05 AM. PAR transmitted to engineering inbox 11:18 AM. No punch-list items outstanding.
Portable berms deployed around 3 pool deck drain inlets prior to any chemical application. Approximately 24 gallons of process wastewater captured from pool deck low-gradient zones. Wastewater transferred to sealed containment and removed from property per FL DEP POTW permit conditions. No discharge to pool or sanitary sewer without authorization.
