Services
Mechanical Engineering
Our mechanical engineering team designs high-performance HVAC systems for hospitals, universities, and commercial buildings. We specialise in energy-efficient solutions that improve indoor air quality while reducing operational costs. By collaborating with architects and consultants, we ensure seamless integration with broader project goals.
Electrical Systems
We deliver tailored electrical designs including photovoltaic systems, emergency lighting, and security infrastructure. Our team uses advanced modelling software to ensure compliance and efficiency. Projects meet sustainability criteria while future-proofing infrastructure for evolving client needs across commercial and healthcare sectors.
Building Information Modelling
Our BIM LOD300-ready solutions enable coordinated 3D documentation with integrated 4D (time) and 5D (cost) data. This reduces on-site delays by 30% through real-time design coordination. Clients receive comprehensive models for construction and facility management, enhancing project transparency and risk management.
Hydraulics & Fire Protection
We design hydraulic systems for stormwater drainage, gas reticulation, and fire protection. Our solutions meet regulatory standards while balancing environmental impact. Specialised systems include rainwater harvesting, medical gas distribution, and effluent disposal tailored to healthcare and industrial facilities.
Vertical Transport
Our consultancy optimises lift traffic analysis and design for multi-storey buildings. We specify systems that ensure safe, efficient movement while meeting sustainability criteria. Services include lift car interior selection and performance analysis to align with project aesthetics and operational requirements.
