How We Work
From Brief to Handover — and Beyond
One accountable engineer across every stage. We prove each design digitally before anything is installed.
Consult & Brief
Requirements, site constraints and feasibility captured against the applicable standards.
Design & Engineering
Cooling loads, hydraulic calculations and coordinated MEP documentation in Revit and AutoCAD.
Simulate & Validate
CFD airflow studies and BIM clash detection prove every system before installation begins.
Install & Supervise
Qualified site supervision keeps workmanship, safety and programme on track through installation.
Test & Commission
Systems are tested, balanced and commissioned against the design intent before handover.
Maintain & Support
Planned maintenance and responsive support keep systems performing long after handover.

03 Project stage
Recommended starting point
Coordinate the full MEP design early
For a new build, early multidisciplinary coordination prevents clashes, protects plant space and gives the cost plan reliable quantities.

Building Systems
One Building. Every System.
We design, coordinate and commission every mechanical, electrical and plumbing service in a building — modelled together in one clash-free schematic. Trace a riser, or open its service.
Six coordinated service risers, one clash-free model. Hover a system to trace its route — tap to explore the service.
- HVAC & Chilled Water Air handling, ductwork, chilled-water plant
- Hot Water Generation Solar thermal, heat pumps, calorifiers
- Plumbing & Drainage Supply, sanitary, stormwater, storage
- Fire Protection Sprinklers, hydrants, wet risers, pumps
- Power & Electrical LV distribution, standby & ICT — supervised
- Medical Gas & LPG O₂, vacuum, AGSS, LPG reticulation
Design Technology
Designed Digitally. Delivered Physically.
We model, simulate and validate every system before installation begins — detecting clashes early, minimising risk and shortening delivery timelines. What we prove digitally is exactly what we commission on site.
- Autodesk Revit (BIM) — model-based design with clash detection before construction
- Autodesk CFD — airflow and heat-transfer simulation for HVAC optimisation
- AutoCAD — precise 2D layouts, schematics and construction documentation
- Pipe Flow Expert — hydraulic calculations that size systems right, first time
Engineering Drawings & Schematics
See the drawings before you commit
Every discipline is issued as a proper drawing sheet — title block, revision history, legend, general notes and calculated sizes. These are illustrative samples drawn on a neutral reference building, watermarked and marked not for construction, so client schemes stay confidential.
