ENGINEERING IN FOCUS
Structure in equilibrium.
Structural order
A building begins with the relationship between its structural grid, use and geometry. Spans, vertical circulation and service zones shape the way the programme can be organised. Reading these relationships together gives the building its underlying order.

Coordinated interfaces
Architecture, structure and mechanical-electrical work meet at openings, shafts, floor zones and equipment spaces. Interface coordination considers these meeting points before they become isolated site problems, connecting a whole-building view with the detail of each package.
Construction sequence
Procurement, access and work fronts influence the sequence in which a design becomes physical. A coherent sequence considers dependencies between packages, temporary conditions and the requirements of the final handover.
From what lies beneath
to what defines the place.
Six connected fields of work, from complete building delivery to the surfaces, systems and external spaces that shape its use.
