By joining our Vietnam team, you will contribute to innovative international projects while working in a dynamic, multicultural environment committed to technical excellence and sustainable development.

2. JOB SUMMARY

ATIXIS Vietnam is looking for an HVAC & Plumbing BIM Modeler & CAD Draughtsman for its Ho Chi Minh City office. Working on projects that run from design through to execution, the role combines 3D BIM modeling in Autodesk Revit, 2D drafting on CAD/Revit and multidisciplinary coordination. The detailed responsibilities are set out below.

3. KEY RESPONSIBILITIES

BIM Modeling (3D)

· Create accurate 3D Revit models of HVAC and plumbing systems – air handling units, fan-coil units, pumps, valves, dampers, fans, ductwork, chilled- and heating-water and refrigerant pipework, domestic water, drainage and fire-protection networks, etc.

· Build the model following the logical HVAC design sequence: first the technical / plant rooms and vertical shafts, then the primary distribution networks, then the secondary networks and terminal connections, and finally the components, accessories and installation details.

· Develop models to the required Level of Development (LOD), up to LOD 400, suitable for installation and as-built purposes.

· Apply good modeling practice: respect clearances and tolerances between systems, keep the correct spacing and bend radius for ducts and pipes, and allow for insulation, drainage slopes and access / maintenance space.

· Keep the model clean and well-structured (systems, naming, levels, worksets and parameters) so it stays coordinated and usable by the whole team.

2D Drafting & Drawing Production

· Produce clear, detailed HVAC and plumbing drawings on CAD / Revit: general arrangement plans, sections, riser and shaft diagrams, schematic (principle) diagrams and installation details.

· Read and correctly interpret design minutes (annotated plans, mark-ups) and translate them accurately into models and drawings.

· Prepare and maintain drawing sheets, legends, tags, schedules and title blocks in line with ATIXIS and project standards.

Coordination

· Work with the other disciplines (architecture, structure and other MEP trades) to detect and resolve clashes and ensure an integrated, buildable design.

· Take part in coordination reviews (e.g. Navisworks) and help track and close clash and design issues.

Data & Model Management

· Incorporate and update equipment and installation data to produce accurate, as-built models.

· Ensure model information (parameters, schedules, quantities) is complete and reliable for downstream use.

Standards & Compliance

· Follow industry standards, project-specific BIM workflows, the BIM Execution Plan (BEP) and naming conventions.

4. JOB REQUIREMENTS

Education & Experience

· Graduated from a university specializing in HVAC, Plumbing, Mechanical or Building Services / MEP Engineering.

· 1 to 3 years of relevant experience (junior to intermediate level).

· Prior HVAC / MEP design experience is strongly desired: the candidate should already understand the logic and successive stages of an HVAC / MEP design (as described under Key Responsibilities), rather than modeling elements in isolation. A first experience in a design office or with a contractor is a strong plus.

Professional Skills

· Knowledge of HVAC and plumbing design and installation applied to buildings.

· Understanding of BIM / MEP modeling good practice and Levels of Development (LOD).

Technical Skills

· Proficient in Autodesk Revit MEP, AutoCAD and Forma.

· Navisworks for coordination and clash detection.

· MS Office (Word, Excel, Outlook).

Language skills

· Good command of written and spoken English. Requirement for effective communication with the BU Manager

Soft skills

· Detail-oriented and rigorous, with a strong focus on model quality and accuracy.

· Team player, comfortable working within a multidisciplinary design team.

· Willingness to learn and to keep developing technical and BIM skills.

5. BENEFITS

· Attractive salary;

· 13th-month and Tet salary bonus;

· Salary review every 6 months;

· Social insurance in accordance with the Labor Law;

· 15 days of annual leaves per year;

· Gift or allowance for holidays, weddings, sicknesses, etc.;

· Company trips & other team-building activities;

· Passionate, talented, young, and driven colleagues;

· Unlimited potential for your career growth because we are small and fast-growing;

· Free snacks, tea, and coffee for a tea break on a regular basis.
