MJA Consulting Engineers

We are a Melbourne-based team of consulting engineers
Specialising in the education, sports and recreation,
industrial and commercial sectors

Peter and Nuwan started MJA Consulting Engineers to provide our clients with a personalised approach to building services engineering. Building services can be simply defined as everything in a building that works – lighting, power, air conditioning, plumbing and fire services. All these services need to provide the practical requirements for building occupants. Occupants need to have an appropriate lighting level, need to be thermally comfortable, be provided with water and need to have fire fighting abilities to remain safe whilst they are within the occupied space.

To achieve a successful compliment of services in a building requires input from professional designers who understand all of the technical and compliance details of every service. It requires a level of understanding of each discipline but also an understanding of the architect’s building and their vision for the building.

In addition, the ability for the builder to construct the building and incorporate the required services is also a consideration that must be paramount in the building services engineer’s mind.

To consistently deliver successful projects, one needs to have a high level of technical knowledge in their discipline, years of experience within the building
and construction industry and clear communication between the members of the design team.

MJA Consulting Engineers possess the technical knowledge, industry experience and people skills to cater for the complexity of your project. MJA consulting Engineers differentiate from other services consultants as our background and our approach incorporates the above attributes and this is applied to all projects undertaken by our office.
