  1. Importance and Benefits of HVAC Shop Drawings

  2. Why are HVAC Shop drawings important? Accurate fabrication Accurate assembly of equipment Accurate installation of building’s HVAC components

  3. HVAC shop drawing services resolve fabrication and installation challenges for multiple stakeholders • General • Contractors MEP Contractors • Construction Companies

  4. How are HVAC Shop Drawings used? Examples HVAC Engineers Mechanical Fabricators Contractors Customize HVAC shop drawings for ductwork with details like size-length and top-bottom elevation for occupant comfort. Create HVAC drawings to manufacture and connect ventilation equipment for improved air transmission and dissipation. Create mechanical shop drawings to manufacture HVAC equipment in the specified location for higher efficiency.

  5. Top 5 Benefits of HVAC Shop Drawings

  6. 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 assembly data accurately and transparently 1 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.

  7. 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 versions of the same component 2 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.

  8. THE CHALLENGE • Inaccurate or incomplete documentation leads to: • Maintenance challenges during construction or handover • Renovation defects Build accurate and detailed documentation 3 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.

  9. THE CHALLENGE • Inaccurate or insufficient count of HVAC components leads to: • Increased cost • Material waste during fabrication and installation Accurate accountability of building components & precise project costs 4 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.

  10. THE CHALLENGE • Clashes or interferences during construction lead to : • Rework • Project delays Resolve errors before setting foot on the field 5 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.

  11. Reduce design iteration time by 50% and cut down manufacturing TAT by 30% with accurate and detailed manufacturing drawings for mechanical components. Hitech CADD Services shows you the way
