Mechanical & HVAC takeoff
Duct runs, diffusers, equipment - from the mechanical sheet.
Mechanical takeoff means measuring duct, counting diffusers, and pricing equipment. Kamai handles all three on the same parse.
Supply, return, and exhaust duct runs are measured from vector polylines - no caliper-on-screen approximation. Diffusers, grilles, and VAVs are counted and typed from the legend.
Equipment schedules (RTU, AHU, VAV, FCU) are read and joined back to the tags they appear under on the plan.
Inputs Kamai reads on mechanical work.
Every device, every fixture, every member - keyed to the legend.
Kamai reads the legend on the mechanical sheet and types each symbol it counts.
What lands in your pipeline.
Every mechanical detection emits a typed record. Here's the shape.
type MechanicalDetection = {
element_id: string;
type: string;
cfm: number?;
duct_run_lf: number?;
room_id: string?;
sheet: string;
