Job Title: HVAC BIM Engineer Location: Fremont, CA Duration: 3-6+ Months Contract to Hire or Extensions
Rate Range: $50-55/hour
SUMMARY:
We are seeking an experienced HVAC BIM Designer to deliver coordinated, construction-ready 3D models for commercial, institutional, healthcare, industrial, or multi-family projects. The ideal candidate has a proven track record producing HVAC BIM content from design development through construction administration, and works effectively across disciplines including architectural, structural, electrical, plumbing, and fire protection teams. This role places a strong emphasis on model accuracy, clash detection and resolution, constructability, and adherence to project BIM Execution Plans (BEPs) and established standards.
RESPONSIBILITIES:
Produce and maintain HVAC BIM models from schematic design through IFC/construction documents and as-builts.
Model mechanical systems to defined Levels of Development (LOD 300–400) and maintain data-rich models, including parameters for equipment tags, flow rates, and pressure drops.
Participate in interdisciplinary coordination meetings, run and resolve clash detection, and proactively identify design issues and constructability concerns.
Collaborate with architectural, structural, electrical, plumbing, and fire protection teams to ensure fully coordinated, construction-ready models.
Support project delivery across design-build, design-bid-build, and IPD or collaborative delivery methods.
Support field teams by responding to RFIs and reviewing shop drawings and submittals against the BIM model.
Maintain compliance with project BIM Execution Plans (BEPs), naming conventions, shared coordinates, and linking strategies.
Generate accurate sheets, schedules, and data extracts from the model to support design and construction teams.
Mentor junior modelers and help enforce quality standards (senior/lead roles).
REQUIRED SKILLS:
Bachelor’s degree in Mechanical Engineering, Architectural Engineering, HVAC Engineering, Building Sciences, or a closely related field preferred.
5+ years of progressive experience in HVAC design and BIM modeling (3–5 years for mid-level roles; 7–10+ years for senior/lead roles).
Proven experience producing HVAC BIM models from schematic design through construction documents and as-builts.
Experience on projects of meaningful scale and complexity (e.g., hospitals, labs, data centers, high-rises, campuses, industrial facilities).
Direct involvement in interdisciplinary coordination meetings, clash detection workflows, and issue resolution.
Navisworks Manage or equivalent – clash detection, aggregation, quantification, and coordination.
AutoCAD, including 2D production and legacy support.
Strong understanding of mechanical systems: airside (AHUs, VAVs, ductwork, diffusers), waterside (chilled/heating water, pumps, piping), refrigeration, controls basics, and exhaust/ventilation.
Working knowledge of applicable codes and standards, including IMC/UMC, ASHRAE (62.1, 90.1, 55, etc.), NFPA, SMACNA, local amendments, and energy codes.
Knowledge of constructability, installation clearances, access/maintenance space, and coordination with structure and architecture.
PREFERRED SKILLS:
BIM 360 / Autodesk Construction Cloud (Client) or similar common data environment (CDE) platforms.
Dynamo or basic computational design/scripting for repetitive tasks and quality control.
HVAC load calculation and energy analysis tools (Carrier HAP, Trane TRACE 3D Plus, IESVE, Client, or equivalent).
Fabrication/detailing tools (e.g., Revit Fabrication Parts, CAM-related workflows) for roles that include detailing.
Point-cloud / reality-capture workflows (Recap, scan-to-BIM) for renovation projects.
Familiarity with other platforms such as Archicad, Bentley, or Tekla is a plus.
