Services
Mechanical Building Services
We design comprehensive mechanical systems including heating, ventilation, and air conditioning. Our specialist expertise covers healthcare-grade ventilation, ultraclean operating theatre systems, and data centre cooling solutions. All designs optimise energy efficiency while maintaining strict regulatory compliance through detailed thermal and airflow modelling.
Electrical Design
Our electrical engineering covers commercial lighting, power distribution, and critical systems. We specialise in high-voltage infrastructure, uninterruptible power supplies, and security systems. Designs incorporate future-proofing for technological changes while ensuring safety and regulatory compliance across all installation types.
Sustainability Modelling
We provide thermal simulation, daylight analysis, and renewable energy integration services. Our approach evaluates building performance through dynamic modelling of solar shading, overheating risks, and energy strategies. This enables optimised EPC ratings and compliance with Part L regulations while reducing long-term operational costs.
CAD Design
Our BIM/CAD capabilities include 3D Revit modelling and 2D drafting for construction documentation. We create detailed as-built drawings from site surveys and develop coordinated design packages that improve construction accuracy and reduce project risks through digital visualisation and clash detection.
Fire Protection Systems
We design integrated fire protection systems combining detection, suppression, and evacuation solutions. Our approach ensures compliance with current standards while maintaining system effectiveness across different building types, including complex commercial and healthcare environments where safety criticality is highest.
