THE ULTIMATE CHECKLIST FOR MEP ENGINEERING IN NEW RESTAURANT BUILDS
Opening a new restaurant is a high-stakes game. Margins are thin, codes are strict, and one overlooked detail in your MEP (Mechanical, Electrical, Plumbing) systems can turn your dream kitchen into a money pit. This checklist isn’t just another generic guide—it’s your playbook for avoiding costly mistakes before they happen. Follow it, and you’ll walk into opening day with systems that work as hard as your team.
WHY mep engineering canada ENGINEERING DECIDES IF YOUR RESTAURANT SURVIVES OR FAILS
MEP isn’t just pipes and wires. It’s the invisible infrastructure that keeps your kitchen running, your guests comfortable, and your health inspector off your back. Get it wrong, and you’re looking at:
– Equipment failures that shut down service during peak hours.
– Energy bills that eat 30% of your revenue.
– Code violations that delay your opening by months.
– Poor ventilation that turns your dining room into a sauna.
Restaurants have unique MEP demands that offices or retail spaces don’t. Your systems must handle grease, steam, high heat, and constant use—all while meeting strict health and safety codes. This checklist ensures you cover every critical detail before construction starts.
PRE-DESIGN: THE FOUNDATION YOU CAN’T SKIP
Define your concept’s MEP needs before blueprints exist.
– Fast-casual with a simple grill? Your HVAC and electrical loads will be lighter.
– Full-service with wood-fired ovens and a sushi bar? You’ll need heavy-duty exhaust, gas lines, and refrigeration.
– Bar-heavy concept? Plan for extra plumbing for sinks, ice machines, and glass washers.
Map your kitchen workflow.
– Where will hot prep, cold prep, and plating happen? Each zone has different MEP needs.
– Will you have a pastry station? That’s a separate refrigeration circuit.
– Where’s the dishwashing area? It needs dedicated hot water and drainage.
Gather equipment specs early.
– Every piece of equipment—ovens, fryers, refrigerators—has specific electrical, gas, or water requirements.
– Get cut sheets from manufacturers. Don’t guess.
– Note voltage, amperage, BTU ratings, and water flow rates.
Check local codes and health department requirements.
– Some cities require grease interceptors for all floor drains.
– Others mandate Type I hoods for any open-flame cooking.
– Fire suppression systems may need specific nozzle placements.
– Call your local building department and health inspector. Ask for a pre-application meeting.
MECHANICAL SYSTEMS: KEEPING THE AIR CLEAN AND THE KITCHEN COOL
Design your HVAC for comfort and compliance.
– Restaurants need 10-15 air changes per hour in the kitchen. Dining areas need 6-8.
– Use demand-controlled ventilation (DCV) to adjust airflow based on cooking activity.
– Separate kitchen and dining room systems to prevent odors from spreading.
Size your exhaust hoods correctly.
– Type I hoods for grease-laden vapors (grills, fryers, woks).
– Type II hoods for steam (dishwashers, pasta cookers).
– Hoods must extend 6 inches beyond the cooking equipment on all sides.
– Calculate CFM based on equipment BTUs. A 4-burner range needs ~400 CFM.
Plan your make-up air (MUA) system.
– For every CFM exhausted, you must supply 90% as make-up air.
– Direct MUA to the hood’s capture zone to avoid disrupting airflow.
– Use tempered air (heated or cooled) to maintain kitchen comfort.
Don’t forget fire suppression.
– Wet chemical systems for Type I hoods.
– Dry chemical or water mist for Type II hoods.
– Nozzles must be spaced per NFPA 96—usually every 18-24 inches.
– Include manual pull stations near exits.
ELECTRICAL SYSTEMS: POWERING YOUR KITCHEN WITHOUT OVERLOADING
Calculate your electrical load accurately.
– A 2,500-square-foot restaurant typically needs 200-300 amps.
– Add 25% buffer for future equipment.
– Use a load calculation tool or hire an electrical engineer.
Plan your panel layout.
– Place panels near high-demand areas (kitchen, bar).
– Avoid running long circuits—voltage drop kills equipment efficiency.
– Dedicate circuits for refrigeration, ice machines, and POS systems.
Design for equipment needs.
– Three-phase power for large motors (walk-in coolers, exhaust fans).
– Single-phase for most other equipment.
– GFCI protection for all outlets in wet areas (bar, dishwashing, prep sinks).
Lighting matters more than you think.
– 50-75 foot-candles in prep areas. 20-30 in dining rooms.
– LED fixtures for energy savings and heat reduction.
– Emergency lighting with battery backup for exits and pathways.
PLUMBING SYSTEMS: WATER, WASTE, AND GREASE MANAGEMENT
Size your water supply lines.
– ¾-inch main line for most restaurants. 1-inch if you have multiple high-demand fixtures.
– Hot water demand peaks during dishwashing. Use a recirculation system to avoid delays.
– Water heaters should recover at 140°F for sanitizing. Use a mixing valve to deliver 120°F to sinks.
Plan your drainage carefully.
– Floor drains every 200 square feet in the kitchen. Slope floors 1/4 inch per foot toward drains.
– Grease interceptors for all kitchen drains. Size based on flow rate—usually 500-2,000 gallons.
– Indirect waste for food prep sinks and ice machines to prevent backflow.
Don’t forget the bar.
– Separate drains for beer taps, soda guns, and glass washers.
– A dedicated grease interceptor if you serve fried bar snacks.
– Hot water dispensers for tea and coffee stations.
Include a grease management plan.
– Grease interceptors must be accessible for pumping. Schedule service every 30-90 days.
– Use enzyme treatments to break down grease between pump-outs.
– Never pour grease down drains—even with an interceptor.
SPECIALTY SYSTEMS: THE DETAILS THAT SEPARATE GOOD FROM GREAT
Refrigeration needs its own plan.
– Walk-in coolers and freezers need dedicated circuits.
– Condensing units should be outside or in a well-ventilated mechanical room.
– Use hot gas defrost for freezers to prevent ice buildup.
Compressed air for kitchen tools.
– Pneumatic tools (sausage stuffers, dough sheeters) need clean, dry air.
– Size your compressor for peak demand. A 5
