Speed of construction

Building structural design, drawings, Bills of Materials, are quickly generated with advanced CAD programmes.
Components are factory-produced on automated production lines
Foundations are prepared as building components are produced.
Assembly on job site is simple - bolted or screwed connections, no welding, little site cutting or modification. No "wet" work. All parts are cut-to-length, pre-punched and individually identified.
"One-source" supply provides co-ordinated deliveries and component compatibility.
