Stephenson&Turner has expertise in all aspects of building services engineering, including:

To excel in the holistic building approach, S&T's engineers work in an integrated way with our architects and other professionals. We believe this focus creates the best engineered solutions for today's complex building types.

Our engineering staff are available to provide an integrated, total building engineering services design or can offer a specialist stand-alone role. The essential element of every building, engineering services have increased in importance, diversity and sophistication. S&T has developed considerable expertise in all areas of engineering building services. In all this work we focus on a 'total building' approach, ensuring design effectiveness, energy efficiencies and environmental sustainability.

Our primary aim is to create comfortable and well-maintained environments for the benefit of building users, operators and owners. Planning for the full integration of building services at design stages allows for cost-effective maintenance in the future.

Our mechanical engineers are focused on market needs and are trend setters. Their expertise covers all types of systems, from traditional systems to innovative systems such as chilled beams, displacement systems and VRV systems.  Our mechanical engineers advocate for maximising the passive design of buildings and are driven to achieve sustainable and energy-efficient solutions.

Stephenson&Turner's mechanical engineers also provide related independent design verification and peer reviews.

Our electrical engineers' expertise covers lighting, lighting control systems, high and low power supplies, distribution, generation and infrastructure. Our lighting design specialists provide a comprehensive service ranging from artificial lighting to natural lighting and emergency lighting, and consider light as an art and a science. Our electrical engineers are also experts on security systems, and communication and data systems.

Stephenson&Turner's engineers are highly experienced in the design of piped water services systems and sanitary and stormwater drainage systems.  Our expertise extends to specialised systems including:

  • Water treatment plants

Stephenson&Turner's fire engineers provide performance-based fire safety design during concept, design and construction phases for new and existing facilities.

Our fire engineers undertake people movement and evacuation modelling for fire and non-fire emergencies. Modelling includes the spread and impact of fire and smoke on people, property and emergency services. The fire safety strategy is a result of fire engineering analysis and modelling, interpretation of codes and standards, and negotiations with authorities and stakeholders.

Our fire engineers design and specify fire detection and suppression systems, including fire detection, wet sprinklers, dry sprinklers, gas flooding, hose reels and extinguishers.  

S&T's fire engineers are established as local leaders and provide related independent design verification and peer reviews. They undertake specific fire safety design where standard solutions are not applicable.

Stephenson&Turner's communications specialists offer a comprehensive consultancy service. Our work covers information and communications technology for all types of projects, including call centres, educational facilities, medical facilities and office buildings.  We design reliable and extendable infrastructures for communication systems to support modern objectives.

Server Room Design

Our integrated design approach makes us the ideal partner in the design of your server room. Bringing together the room layout, air conditioning, fire protection, environmental monitoring, power supplies (including dual supplies, UPS and generators), lighting and network physical infrastructure with our understanding of the special requirements of current IT systems, we offer designs that optimise your current requirements and are flexible enough to handle your future needs.

We have designed server rooms for hospitals and defence, commercial and government organisations.

Vertical transport including lifts, hoists, escalators and travelators, are among the most utilised of assets in today’s buildings. Their performance and appearance are vital to the image of the facility and impact directly on the perceived quality of the building as seen by its tenants and visitors. Stephenson&Turner brings decades of expertise in consulting, engineering and technology to the design and management of vertical transport. Our service includes clear analysis, independent, cost-effective recommendations, and attention to detail – from standards and code compliance to aesthetic considerations.
