Mechanical
HVAC, plumbing and plant-room design balanced against comfort, code compliance and what the building will cost to run.
Mechanical drawings coordinated, priced and formatted for the reviewer who has to approve them.
Who this is for Contractors, developers and technical offices needing a mechanical package taken from load to layout.
Price this scopeWhat you receive
Cooling and heating load calculation
A room-by-room load model with the design conditions, envelope data and occupancy stated, so a reviewer can rerun it.
System selection and equipment schedules
The system chosen against capital cost, running cost and maintenance access, with schedules a procurement team can price.
Ductwork and pipework layouts
Sized, routed and coordinated against structure and the other services, at the levels the installer sets out from.
Plant room and chilled water design
Plant layout, hydraulic design, pump selection and the maintenance envelopes the plant will actually need.
Control philosophy and sequence of operation
Written so the controls contractor can program from it and the commissioning team can test against it.
Piping isometrics for prefabrication
Spool drawings issued for off-site fabrication, with the joint types and supports called out.

- Sustainable Energy-efficient design, evidenced.
HVAC, plumbing and plant-room design balanced against comfort, code compliance and what the building will cost to run.
How it is produced
Loads before layouts
Nothing is routed until the load model is settled. Re-routing a duct because a load moved is the commonest avoidable rework.
Running cost is a design input
Efficiency is compared at selection, not reported after. SBC 601 and ASHRAE 90.1 set the floor, not the target.
Coordinated in the federated model
The mechanical model is federated with structure and the other services as it is drawn, not once it is finished.
Maintenance access is drawn
Coil pull, filter access and valve reach are modelled as volumes, because a plant room that cannot be serviced fails on year two.

Questions clients ask
Do you design for Civil Defence and municipality review?
The drawings are formatted for that review from the first issue, and comment responses are handled through to approval.
Can you value-engineer an existing mechanical design?
Yes. We rerun the load model first: most savings come from a load assumption nobody revisited, not from downsizing equipment.
Do you produce the energy model as well?
Yes, and it is priced under LEED and green building. The mechanical model feeds it, so the two describe the same systems.
A question that is not here?
Ask the engineer who would run your project. Send the drawings and the answer comes back in writing.
Send us one package.
Send a package and you get a scope, a fixed price and a delivery date within two working days.
