Mechanical services design for commercial kitchens, workshops and buildings. Airflow calculations, fan duties, duct sizing, make-up air and gas interlocks, issued as a calculation note and drawing package that mechanical contractors can price and build from. Designed to AS 1668.2 and AS/NZS 5601.1.
Four types of work, one method: real equipment data, cited clauses, calculations you can check line by line.
Restaurants, cafes, bakeries and production kitchens. New fit-outs, or a check on whether the canopies, ducts and fans a previous tenant left behind can be reused.
The other half of every exhaust system, plus the everyday ventilation a building needs to pass approval.
Kitchens full of ovens and fryers, offices, workshops. How much heat is in the room, and what it takes to take it out.
Workshops and plants where the air carries welding fume, dust or process vapour, drawing on years of industrial plant engineering.
Most problems on site come from designing one part at a time. I design the whole loop so the numbers agree with each other.
Written for the builder, the mechanical contractor and the council officer who each read a different page.
Equipment list, floor plan, a few photos of the ceiling and roof. A free call to agree the scope, then a fixed fee.
Canopy sizes, fan positions and budget duties, so the builder and contractors can plan and price early.
Measurements, roof layout and the manufacturer data for the real appliances replace every assumption.
Calc note, drawings, schedules and the compliance matrix, checked independently before it leaves.
Answers to tender questions and RFIs, and review of the contractor's submitted equipment.
Clear on scope: I do the engineering design and calculations as a mechanical engineer (MIEAust). The licensed mechanical contractor supplies, installs and commissions the system and issues its compliance certificates, and gas work is done and certified by a licensed gasfitter. Where a job needs certification or sign-off from a registered practitioner, that is coordinated with one, and I tell you upfront when it applies.
Before you price a kitchen job, read what really sets the cost of a kitchen exhaust in WA: seven design decisions from a Perth bakery fit-out, with the clauses and numbers.
Typical clients: builders and fit-out companies, restaurant, cafe and bakery owners, mechanical contractors who need a design to price against, and workshops and plants with fume or heat problems. NDA on request.
Send your equipment list and floor plan. Free scoping call, then a fixed-fee design package your contractors can price.
