3D BIM modeling of HVAC systems in Revit MEP — ductwork, piping, equipment, multi-discipline coordination, and IFC export for commercial, industrial, and public projects in Chile.
What we deliver
LOD 200–400 · Ductwork, piping, equipment
Full three-dimensional modeling of all HVAC systems in Autodesk Revit MEP: supply/return air ductwork, refrigerant piping, chilled/hot water networks, indoor and outdoor units, fan coils, AHUs, chillers, and exhaust systems. Standard delivery at LOD 300 (defined geometry, location, orientation, and quantity); LOD 400 available for fabrication and advanced coordination.
Clash detection · Navisworks · BIM 360
Coordination with other disciplines (structural, electrical, plumbing, fire protection) via clash detection in Autodesk Navisworks or BIM 360/ACC. Identification and resolution of conflicts before construction — reduced RFIs and field change orders. BIM coordination meetings with the project team as needed.
Plans, sections, details, schematics
Extraction of 2D construction drawings directly from the 3D model: HVAC floor plans by level, mechanical room sections and profiles, equipment connection details, piping isometrics, and equipment schedules with technical specifications. Full consistency guaranteed between 3D model and 2D drawings.
Automated quantities · Bidding basis · Full traceability
Export of quantities and take-offs directly from the BIM model: duct lengths by cross-section and segment, pipe lengths by diameter and material, equipment quantities by type and capacity, diffuser and grille counts. Direct basis for tendering and costing, with full traceability to model elements.
IFC 2x3 / IFC 4 · BIM management · Open coordination
Export of the HVAC model to IFC (Industry Foundation Classes) 2x3 or IFC 4 format for integration with BIM management platforms (BIM+, ACC, ProjectWise, Procore) and review by the BIM Manager or client. Compliance with EIR (Employer Information Requirements) when specified by the project.
Plan BIM Chile · MINVU · MOP · Mercado Público
Chile's Plan BIM (MINVU/MOP) requires BIM on public building projects over UF 5,000 since 2020, with growing coverage toward smaller projects. D&Z Building delivers BIM-compliant HVAC models per Plan BIM Chile requirements: specified LOD, CDE (Common Data Environment) integration, and deliverables per the project's BEP (BIM Execution Plan).
FAQ
BIM HVAC (Building Information Modeling for HVAC systems) is the process of creating an informed, three-dimensional digital model of all HVAC systems in a building: air ductwork, refrigerant or chilled-water piping, equipment (chillers, fan coils, VRF), and their technical attributes. Unlike traditional 2D drawings, a BIM model contains precise geometry, equipment specifications, fabrication data, and relationships with other building systems. This enables conflict detection with other disciplines before construction, reducing field changes and cost overruns.
LOD (Level of Development or Level of Detail) defines how much information a BIM model element contains. LOD 300 means elements have geometry, location, orientation, quantity, and size defined with sufficient precision for coordination with other disciplines and quantity take-offs. LOD 200 is schematic (approximate shape only). LOD 400 includes fabrication details. For most design and coordination projects, LOD 300 is the standard required level.
It does not replace drawings — it generates them. 2D construction drawings (plans, sections, details) are extracted directly from the 3D model, guaranteeing full consistency between the three-dimensional model and the approved-for-construction drawings. The 3D model is the single source of truth; 2D drawings are views of the model. This workflow eliminates discrepancies that occur when 2D drawings are produced manually without a model reference.
Chile's Plan BIM (MINVU/MOP) establishes progressive BIM adoption for public projects: mandatory since 2020 for public building projects over UF 5,000; since 2022 for major public infrastructure. For private projects, BIM is required primarily by international project owners, retail chains, hotel groups, and shopping centers following global corporate standards. The Chilean private market adopts BIM voluntarily but at a growing pace.
Cost depends on project size and LOD required. For a single 1,000 m² office floor (LOD 300, no full MEP coordination): approximately UF 20–60 (≈ USD 660–2,000). For a full 10-story building with complete MEP coordination: UF 150–500. For a complex industrial or healthcare project with IFC export and BIM coordination meetings: UF 300–1,000+. BIM modeling typically represents 2–5% of total HVAC engineering fees, and the investment is recovered in reduced field change orders. UF (Unidad de Fomento) ≈ USD 33 in 2025.
Yes — that is the most common scenario. The architect provides the architectural model in Revit or IFC, and D&Z Building models the HVAC on top of that base. To coordinate with other MEP disciplines (electrical, plumbing), we need those discipline models in Revit or IFC to run clash detection. If other disciplines do not have BIM models, we can still model the HVAC on the architectural model and coordinate in 2D with the other disciplines.
