How are HVAC Shop Drawings used?
Examples
HVAC Engineers Mechanical Fabricators Contractors
Customize HVAC shop Create HVAC drawings to Create mechanical shop 
drawings for ductwork with manufacture and connect drawings to manufacture 
details like size-length and ventilation equipment for HVAC equipment in the 
top-bottom elevation for improved air transmission specified location for 
occupant comfort. and dissipation. higher efficiency. 
Top 5 Benefits of
 
HVAC Shop Drawings
THE CHALLENGE
Fabrication and installation inaccuracy due to:
 Uncoordinated and clash-ridden HVAC layouts. 
 Flawed or incomplete HVAC drawings with missing material 
specifications or installation details resulting in rework.
Communicate design and 
1 assembly data accurately 
and transparently THE SOLUTION
HVAC shop drawings extracted from coordinated 3D BIM models 
provide:
 Drawing accuracy and clarity with model-extracted HVAC shop drawings.
 Multiple views of HVAC equipment in 3D for a clear perspective. 
 Detailed HVAC product dimensions, material type, intended weight, etc. 
THE CHALLENGE
Without detailed shop drawings: 
 Fabrication of multiple units can be inaccurate and time consuming. 
 Inaccuracies in design lead to rework and material waste. 
Manufacture multiple 
2 versions of the same 
component THE SOLUTION
Detailed HVAC shop drawings extraction helps in:
 Creating replicas of the same component example - roof joints.
 Replacing faulty HVAC components like ducts, pipes, air handling units 
during construction or operations.   
 Saving on rework, reducing material waste, and conserving 
manufacturing time and cost.
THE CHALLENGE
Inaccurate or incomplete documentation leads to:
 Maintenance challenges during construction or handover 
 Renovation defects 
Build accurate and

detailed documentation
THE SOLUTION
Accurate & detailed HVAC documentation and shop drawings:
 Resolve maintenance challenges by easy referral to detailed 3D 
models as required.
 Resolve defects. 
 Help procure build approvals from the planning authority. 
THE CHALLENGE
Inaccurate or insufficient count of HVAC components leads to:
 Increased cost 
 Material waste during fabrication and installation
Accurate accountability 
4 of building components 
& precise project costs THE SOLUTION
Accurate quantity takeoffs and cost estimates produce:
 Precise costs to procure manufacturing materials. 
 Precise schedule calculations.  
 Precise material procurement that cancels out material waste and 
overstocking.
THE CHALLENGE
Clashes or interferences during construction lead to :
 Rework
 Project delays 
Resolve errors before

setting foot on the field 
THE SOLUTION
Identifying and resolving clashes during the pre-construction stage:
 Saves on costly rework and project delays.
 Enables HVAC fabrication & installation with information-driven insights.
 Enable precise HVAC component manufacturing, seamless site 
construction, and time savings. 
Reduce design iteration time 
by 50% and cut down 
manufacturing TAT by 30% 
with accurate and detailed 
manufacturing drawings for 
mechanical components.
