Stages and coordination
We deliver concept, technical and detailed designs and coordinate the WSS part with architecture, structure, HVAC and electrical to avoid clashes on site.
BIM design
We model the WSS part in BIM, so clashes with the structure and other services are found at design stage and quantities come straight from the model. More about BIM design →
