RAIN ENGINE is developed by a founder-led engineering and software team working close to real MEP planning practice.
The product grew out of practical problems that are familiar to planning teams: incomplete project information, changing project context, assumptions hidden in spreadsheets and technical results that need to survive review, revision and handover.
RAIN ENGINE is designed to make that work more structured. It helps prepare inputs, make assumptions visible, support technical checks and connect results to reviewable outputs. The engineer stays in control of the decision.
RAIN ENGINE is developed by engineers and software specialists working close to real MEP planning practice. Its direction is shaped through internal case studies and practical feedback from active engineering environments. BWK Engineers, a building services engineering practice, has been involved from the early concept phase, bringing input from real project processes, review situations and controlled case studies.
The goal is to make repetitive technical work easier to inspect, correct and document from the inside, with responsibility staying clearly with the engineer.
Built around the problems that appear during coordination: incomplete information, changing project context, unclear assumptions and revision pressure.
Results are useful only when the engineer can see where they came from, what was assumed and what still needs a decision.
Project context, technical assumptions and relevant standard orientation remain visible for review.
Dejan Bajić is a co-founder of RAIN ENGINE and Partner at BWK Engineers, with over two decades of experience in building services engineering on large-scale projects. At RAIN ENGINE, he contributes to product strategy, technical direction and the connection between engineering practice and software development.
Nikola Kadić is a co-founder of RAIN ENGINE and Partner at BWK Engineers, with around 25 years of experience in building services engineering. At RAIN ENGINE, he contributes deep technical knowledge of engineering planning processes — particularly where structured information handling and engineering review logic intersect.
Milan Vučićević is a co-founder of RAIN ENGINE and Partner at BWK Engineers, with around 20 years of experience in building services engineering. At RAIN ENGINE, his focus is on the engineering logic behind selection processes and technical assessments — the work RAIN ENGINE is designed to structure and make reviewable.
The best conversations begin with a clear project context and a concrete review workflow.
