🧪 Labs & Tech Spaces

  • Fume hoods: exhaust CFM per sash; bypass/variable volume; face velocity setpoint; sash interlocks.
  • Work surfaces: epoxy/phenolic; acid-resistant waste ties; safety shower/eyewash nearby.
  • Gas rails/vacuum/air point-of-use by MEP; verify regulators & quick connects.
  • Dedicated power with clean grounding; UPS to sensitive equipment as required.

🏥 Healthcare / Sterilization

  • Sterilizers/warmers: steam, condensate coolers, RO/DI water, dedicated vents; seismic bracing & floor drains.
  • Ceiling booms/lights: structure inserts, Unistrut grids, power/data/medical gas umbilicals by others.
  • Imaging (CT/MRI): shielding, RF rooms, quench vent (MRI), chilled water/electrical distribution coordination.

🚚 Loading Dock Equipment

  • Levelers (pit/vertical/edge-of-dock) — capacity by forklift/axle load; power unit location; interlocks.
  • Vehicle restraints, dock seals/shelters, bumpers; control panel with traffic lights.
  • Door sensors/heaters (cold rooms), bollards & guardrails; trenching for conduits.

🏟️ Athletic / Stage & Theater

  • Bleachers/backstops: verify support steel, wall pockets, fall protection, motor power & controls.
  • Rigging: beam clamps/points, line-sets, motorized hoists — structural engineer sign-off.
  • Scoreboards/shot clocks: sightlines, power/data, mounting heights.

🧮 Quick Math & ROM Sizing Helpers

Electrical Load (kVA)

kVA ≈ (V × A × √3) ÷ 1000 (3-phase). Add 25% for continuous where required.

Grease Hood CFM (ROM)

Wall hood: 150–200 CFM/lf; Island: 250–300 CFM/lf (verify with mfr & code).

Gas Line Estimate

Sum BTU → size off length/pressure drop charts. Quick check: 1 CFH ≈ 1,000 BTU.

Dish Booster Sizing

kW ≈ (GPH × ΔT × 8.33) ÷ (3412 × efficiency). Typical 9–24 kW (per machine).

Dock Leveler Capacity

ROM = (forklift + load) × safety factor (1.25–1.5). Verify cycles & lip length.

Seismic Anchorage

Check overturning, sliding, drift; use ICC-ES anchors; edge distances/embeds per ESR.

✅ Submittals & QA

  • Complete cut sheets showing model, utilities, loads, clearances, weight, connections.
  • Shop drawings with plans/elevations/sections, penetrations, and anchorage details.
  • Coordination/BIM clash results; sleeve/insert drawings; curb details.
  • Factory start-up reports, training logs, O&M manuals, warranty letters.

🧰 Installation Notes

  • Verify rough-in locations off finished dimensions; allow for bases, cove, wall panels.
  • Use listed flexible connectors (gas/water) where permitted; restrain appliances on casters.
  • Provide access panels to valves, traps, and disconnects; label circuits and shut-offs.
  • Balance airflow (hoods/fume hoods) after start-up; confirm interlocks.

🦺 Safety (Field)

  • Rigging plans for heavy lifts; rated slings; taglines; exclusion zones.
  • Lockout/Tagout for gas/electrical; combustion air and ventilation during burn-in.
  • Hot-work permits for duct/hood mods; fire watch & shielding.
  • Ergonomics: team lifts, dollies, skates; protect finished floors/walls.

Answers: (1) Electrical, Gas, Water, Waste, Vent/Exh, plus Clearances, Weight/Anchors, Data/Controls. (2) Type I handles grease vapors (fire suppression & grease duct required); Type II handles heat/steam only. (3) Exhaust/CFM with duct, make-up air, sash/controls (plus power & acid-resist waste as needed). (4) Prevent condensation and frost heave; control moisture migration. (5) kVA = 208×48×√3 ÷ 1000 ≈ 17.3 kVA. (6) 10 ft × ~150–200 CFM/lf = 1,500–2,000 CFM (verify). (7) Capacity vs axle loads; interlock/controls and vehicle restraint specs; guardrails/bumpers. (8) Stamped calc/shop drawings, ICC-ES anchor ESRs, inspection reports/photos. (9) Movement for cleaning/thermal; vibration isolation and serviceability. (10) Factory start-up forms, O&M manuals, warranties, training logs, as-builts.
