• Identifying and confirming design changes driven by local regulatory or environmental conditions — e.g., jurisdiction-specific energy/mechanical codes, water-use restrictions, and permitting requirements.
• Accounting for climate/site-driven design impacts — high ambient temperature derating on HVAC and refrigeration, condenser sizing, and equipment performance in extreme heat/arid conditions.
• On-site inspections — Conduct field inspections to verify installed mechanical systems match approved plans and specs; document deficiencies and track them to resolution.
• BMS coordination — Coordinate building management system (BMS) scope, controls sequences, and integration issues with TEAMS (our BMS host/management vendor) and other stakeholders.
• Test & Balance (T&B) management — Manage T&B contractors; verify airflow, water balance, and system performance meet design intent; review and approve T&B reports.
• Post-opening system monitoring — Monitor mechanical system performance after grand opening; identify underperforming or failing equipment early.
