HVAC Drafting

TMG performs HVAC drafting for contractors, consultants, manufacturers, architects and engineers.

Typically four sections and one plan are generated for each room.

Details generated include the height at all nodal points, cross sectional measurements and airflow figures for all segments.

For complex designs, the output is often generated from a 3D model that TMG builds for the purpose.

Equipments drafted include air conditioners, AHUs, ventilators, blowers, duct noise filters, duct dampers, duct reducers, duct attenuators, duct fire valves and water piping with accessories.

Advantages

$11 per hour instead of $35 per hour for drafting work
Work supervised by experienced engineers
Pay-per-use only: no minimum monthly fee!

Inputs Required From the Customer

HVAC schematic
Preferred position of equipments if any
Preferred size and location of wall, floor and ceiling openings if any
Location of external mating ductwork and pipework
Specific guidelines for clearances and physical layering, if any
Manufacturers' data sheets for machinery (with dimensions)
Duct and pipe selection charts with boundary curves
3D HVAC symbol library (if specific symbols required)
License for preferred 3D HVAC design application (other than AutoCAD)

What We Will Do for You

Refer to the HVAC equipment data sheets you provided and create non-detailed, scaled 3D block objects of each one
Based on airflow figures in the schematic you provided, select each duct’s shape and cross-sectional area
Place the equipment blocks in accordance with your preferred position diagram
Route ducts and water pipes according to the schematic you provided (also considering access to each part of the room) following the guidelines for clearances and layering you provided
Add accessories to the ducts and pipes
Generate a scale 3D model of the completely fitted out HVAC room
Generate 2D sectional installation drawings with annotations and dimensions for installers to use on site
