Why Choose BSDG?
Melbourne's building services engineers — trusted across Australia for over 20 years.
BSDG is led by registered engineers with deep hands-on experience across every discipline we offer. Director Arthur Dolezal has been managing and delivering complex building services projects for more than 20 years, supported by a team of registered practitioners across all building services disciplines. Our engineers hold registrations across Victoria, NSW and Queensland, with successfully delivered projects in Western Australia as well.
What sets us apart is the breadth of our in-house capability. Rather than outsourcing across multiple consultancies, our clients work with a single, coordinated team — reducing risk, improving communication and keeping projects moving.
From residential apartments and restaurant fit-outs through to hospitals, high-rise developments and large-scale retail centres, we bring the same rigour and attention to detail regardless of project scale.
How We Do It
A structured approach to building services engineering, from brief to handover.
Every project we take on follows a proven process designed to deliver clarity, efficiency and confidence at every stage. Whether you’re an architect mapping out a new development or a builder navigating a complex fit-out across Melbourne or greater Victoria, you’ll always know where your project stands.
Understand Your Brief
We start by listening. Before any design work begins, we take the time to understand your project goals, site constraints, budget parameters and programme. Getting this right upfront avoids costly changes down the track.
Coordinated MEP & Fire Services Documentation
Our in-house capability across all building services disciplines means your engineering documentation is coordinated from a single point of accountability. No gaps, no conflicting drawings, no finger-pointing between consultants.
Design for Buildability
We design with construction in mind. Our documentation is produced to a standard that supports design & construct delivery, contractor tendering and council approval — reducing RFIs and keeping your programme on track.
Communicate Proactively
We don't wait for problems to surface. Our team of registered building services engineers maintains regular communication with architects, builders and contractors throughout the design and documentation phases so issues are resolved early and decisions are made with the right information.
Deliver on Time and on Budget
Our commitment isn't just a tagline. We've built long-term client relationships because we consistently meet programmes and respect budget constraints without compromising design quality.
