Services
Mechanical Engineering
We design mechanical systems including heating, ventilation, and air conditioning for commercial and industrial buildings. Our expertise covers low-temperature hot water systems, chilled water systems, and heat recovery solutions. With experience in complex environments like cleanrooms, we ensure efficient, compliant installations tailored to client needs.
Electrical Engineering
Our electrical design services include emergency lighting, standby generation, and data installations for diverse sectors. We specialise in high-voltage systems, fire alarms, and security infrastructure. Our non-design services cover fault analysis and reliability assessments to maintain operational continuity for critical facilities.
Controls Engineering
We implement building management systems (BMS) and process control solutions using PLC/SCADA technologies. Our designs optimise energy efficiency and integrate with preventative maintenance systems. This ensures precise environmental control and fault monitoring for industrial and commercial operations.
Cleanroom Design
We create ISO-compliant cleanrooms with HEPA filtration, temperature, and humidity control. Our designs address pressurisation cascades and contamination protocols for pharmaceutical, semiconductor, and research facilities. This ensures compliance with stringent international standards for critical manufacturing spaces.
Expert Witness
Our expert witness service investigates building system failures, providing forensic reports for legal disputes. We analyse incidents like pipe bursts, electrical faults, and HVAC malfunctions. This supports insurance claims and legal proceedings with technical evidence and professional testimony.
