20+ years of HVAC design on buildings ranging from single residences to 250,000+ m² multifunctional complexes. Revit MEP · Navisworks · Dynamo · Python for the Revit API · AI-assisted BIM.
Israel / Georgia · Open to remote, hybrid, and on-site engagements globally Russian (native) · English (professional)
Summary
Chief HVAC Engineer and BIM Coordinator with 20+ years of hands-on design and site experience in heating, ventilation, and air conditioning systems — from single residences to the Gazprom Headquarters multifunctional complex in Minsk (8.27 ha, 250,000+ m², 20+ engineering disciplines coordinated on a federated BIM model). I have worked every side of the table: designer, chief specialist, client-side technical lead, peer reviewer, and BIM coordinator.
My mission is to deliver projects that balance the client’s wishes, energy-saving technology, and a disciplined price / quality trade-off. The last decade has combined traditional HVAC engineering with BIM coordination and Dynamo / Python automation, and I am now extending that combination into AI-assisted BIM workflows — the emerging “BIM + AI” and “BIM + Python for HVAC” space.
What I bring
- Full HVAC design lifecycle: concept → calculations → drawings → specifications → cost estimate → site supervision → commissioning
- Peer review and code-compliance QC of contractor and consultant drawings
- Energy audits of existing systems with documented savings recommendations
- BIM coordination across 20+ disciplines on federated Revit models
- Revit API / Dynamo / Python automation — up to 80% reduction in repetitive modeling tasks
- Client-facing technical leadership in Russian and English
- Mentoring and team leadership of junior MEP engineers
Core Competencies
| Area | Detail |
|---|---|
| HVAC Design | Heating, ventilation, air conditioning, and plumbing for commercial, institutional, industrial, and mission-critical facilities. Load calculations, equipment selection, ductwork and piping layout, specifications, bills of materials, and cost estimates. |
| Peer Review & QA/QC | Code-compliance and quality review of contractor and consultant drawings. Multi-discipline coordination with structural, architectural, and electrical teams. |
| Energy Audit | Review of existing HVAC systems with recommendations for energy savings — residential, commercial, and industrial. |
| BIM Coordination | Revit (MEP / Architecture / Structure), Navisworks Manage clash detection, federated model management, BIM Execution Plans, coordinate-system alignment, family libraries, version migration. |
| BIM Automation | Dynamo graphs and Python scripts via the Revit API — parameter sync, automated schedules, clash report generation, view / sheet automation, custom family workflows, model QA checks. |
| Bid & Proposal | Contractor bid estimating, proposal writing, and technical client presentations. |
| Project Management | Technical management of design work, monitoring design-stage decisions, fund expenditure, and delivery against design-estimate documentation timelines. |
| Client-Side Engineering | Representing the customer in multi-contractor environments — issuing instructions, providing initial data, enforcing technical standards, chairing coordination meetings. |

Independent HVAC design practice covering commercial and public buildings, high-rise buildings, hotels, medical institutions, residences, sports facilities, restaurants and kitchen ventilation, clean rooms, data centers, industrial air conditioning and local exhaust, laboratories, museums and archives, power plants, and industrial-environment ventilation.
Featured Project — Gazprom Center, Minsk
Oct 2014 – Present · Associated with Gazprom Transgaz Belarus
8.27 ha site accommodating the Headquarters of the Gazprom Group, administrative and office buildings, a hotel with conference center, sports center, education and child development center, medical center, retail area, amphitheatre, recreational area for city residents, and ground-level + underground parking. 20+ engineering disciplines coordinated on a federated BIM model.
BIM + AI and BIM + Python for HVAC
Beyond traditional HVAC design and BIM coordination, I actively develop in the emerging intersection of digital engineering, Python automation, and AI for MEP / HVAC workflows — a niche where few practicing HVAC engineers can credibly operate.
BIM + Python for HVAC — already in production use on my projects:
- Dynamo + Python (Revit API) automation of HVAC schedules, equipment lists, and duct / pipe parameter propagation
- Automated clash-report generation and routing to discipline owners
- Model QA scripts: checks for missing parameters, orphaned families, coordinate drift
- Bulk family creation and library management via scripted workflows
- Export of HVAC calculation inputs from Revit to external load-calculation tools and back
BIM + AI — active development direction:
- AI-assisted clash triage — using LLMs to classify, cluster, and prioritize Navisworks clash reports so engineers spend time on real issues, not duplicates
- LLM-generated HVAC specifications — turning design intent notes into draft specification text, with human review as the final step
- Vector search over project archives — semantic search across years of HVAC drawings, specs, and calculations to accelerate peer review and precedent lookup
- Code-compliance copilots — LLMs assisting with SNiP / ASHRAE / local code lookup and cross-referencing during design review
- Python + local LLM inference for confidential project environments where cloud AI is not permitted
This places me in a rare blue-ocean profile: a chief HVAC engineer with 20+ years of project delivery and a working, hands-on stack for BIM automation and AI assistance. Most BIM-AI tooling today is built by software developers without domain engineering experience, and most HVAC engineers do not code. I do both.
Target roles
- BIM Manager / BIM Coordinator for HVAC-heavy projects (data centers, hospitals, high-rises)
- Digital Engineering Lead inside an MEP / AEC firm building Revit-API tooling
- HVAC Engineer + BIM Automation hybrid role on a flagship project
- Consultant for BIM + AI adoption inside HVAC design offices
- R&D or product role at a BIM-AI / construction-tech startup needing genuine HVAC domain authority
