🎯 Role Definition

An HVAC Drafter serves as the crucial link between engineering theory and on-site construction. This professional is responsible for translating the complex designs of mechanical engineers into clear, precise, and actionable technical drawings and 3D models. Using specialized software like AutoCAD and Revit, the HVAC Drafter creates the detailed blueprints for heating, ventilation, and air conditioning systems that are essential for building functionality, occupant comfort, and energy efficiency. More than just a technician, this individual is a spatial problem-solver, ensuring that all components fit and function correctly within the larger architectural and structural framework of a building project. Their work is fundamental to successful project coordination, fabrication, and installation.

Core Responsibilities

Primary Functions

  • Develop highly detailed and accurate 2D and 3D drawings of complex HVAC systems, including ductwork, hydronic piping, and equipment placement, using AutoCAD and Revit MEP.
  • Create comprehensive construction and fabrication drawings derived from engineering concepts, performance specifications, and architectural design documents.
  • Perform rigorous clash detection and coordination within 3D BIM models using Navisworks to proactively identify and resolve conflicts between HVAC, structural, architectural, and other MEP systems.
  • Prepare meticulous ductwork and piping shop drawings that conform to SMACNA standards and project-specific requirements, ensuring they are ready for fabrication and field installation.
  • Collaborate actively with mechanical engineers, architects, and project managers to fully grasp design intent and ensure all drawings accurately reflect the specified scope of work.
  • Generate precise spool sheets, isometrics, and bills of materials (BOMs) to support efficient prefabrication, procurement, and cost-tracking processes.
  • Thoroughly review and interpret submittal data and specifications for HVAC equipment to ensure proper sizing, clearance requirements, and connection points are accurately reflected in the models.
  • Maintain and manage all project drawing files with strict version control, systematically incorporating revisions and adhering to established company and client drafting standards.
  • Actively participate in weekly BIM coordination meetings, clearly presenting identified clashes and proposing viable, cost-effective solutions to the integrated project team.
  • Skillfully convert design development sketches and redline markups from engineers into professionally drafted, coordinated, and ready-for-construction documents.
  • Produce detailed equipment pad layouts, roof curb drawings, and structural support details that are critical for guiding proper field installation and ensuring system stability.
  • Develop clear and informative schematic diagrams, such as control schematics, piping and instrumentation diagrams (P&IDs), and system flow diagrams, to illustrate system logic.
  • Ensure all drawings and models rigorously comply with relevant local, state, and federal building codes, as well as ASHRAE, NFPA, and other applicable industry standards.
  • Assist in performing on-site surveys and field measurements to verify existing conditions, capture precise data, and guarantee the accuracy of as-built drawings.
  • Create, manage, and maintain a library of Revit families and AutoCAD blocks specific to HVAC components to enhance drafting efficiency and promote standardization across projects.
  • Prepare complete drawing sheet sets for official project milestones and permit submissions, ensuring all title blocks, notes, legends, and details are accurate and professionally presented.
  • Generate detailed sectional views, elevations, and 3D isometrics to clarify complex installation sequences and spatial relationships for field personnel.
  • Methodically revise drawings and models in response to feedback from Requests for Information (RFIs), Architect's Supplemental Instructions (ASIs), and unforeseen field condition reports.
  • Coordinate drawing layouts and system routing with other trade disciplines, including electrical, plumbing, and fire protection, to achieve a fully integrated and clash-free building model.
  • Support the final project turnover process by preparing meticulous as-built drawings and documentation that accurately reflect the final installed conditions for the building owner.
  • Calculate preliminary ductwork and piping sizes based on initial engineering data to facilitate the early stages of the modeling and coordination process.
  • Plot, batch, and electronically issue complete drawing sets to clients, general contractors, and other key project stakeholders according to the project delivery schedule.

Secondary Functions

  • Support project managers and estimators by performing detailed material takeoffs directly from drawings and 3D models.
  • Contribute to the continuous improvement of the organization's drafting standards, templates, and BIM Execution Plans (BEPs).
  • Collaborate with the prefabrication shop to troubleshoot and resolve any discrepancies between shop drawings and fabricated components.
  • Participate in internal project kick-off meetings and design review sessions to gain a comprehensive understanding of project goals and constraints from the outset.

Required Skills & Competencies

Hard Skills (Technical)

  • High proficiency in AutoCAD MEP for creating and editing 2D mechanical drawings and schematics.
  • Advanced proficiency in Revit MEP for 3D modeling, documentation, and working within a Building Information Modeling (BIM) environment.
  • Strong experience with Autodesk Navisworks Manage for model aggregation, clash detection, and coordination reporting.
  • A solid understanding of commercial and industrial HVAC systems, including air distribution (VAV, CAV), hydronic systems (chilled and hot water), and associated equipment.
  • In-depth knowledge of industry standards, particularly SMACNA for duct construction and fabrication, and a working knowledge of ASHRAE principles.
  • The ability to expertly read and interpret architectural, structural, and multi-disciplinary MEP blueprints, specifications, and contract documents.
  • Proven experience creating detailed, fabrication-level shop drawings and piping spool sheets for off-site prefabrication.
  • Familiarity with Bluebeam Revu for reviewing, marking up, and collaborating on PDF drawing sets.
  • Competency in creating and managing parametric BIM content, specifically custom Revit families for HVAC equipment and components.
