# Commercial & Mixed-Use

## Engineering adaptable, sustainable workplaces

Hybrid working and ESG requirements have reshaped demand for commercial office
space. Occupiers increasingly prioritise flexibility, low embodied carbon and
long-term adaptability, and the trend toward tall, mixed-use developments is
producing vertical precincts where retail, hospitality, residential and
commercial uses intersect within a single structure.

### Integrated capability across the project lifecycle

SYSTRA delivers commercial and mixed-use projects through structural
engineering, with supporting civil, construction, façade, flooding,
geotechnical, materials and sustainability capabilities – across office
buildings, tenant interiors, new builds, refurbishments, high-rise towers and
large-scale business precincts.

Design solutions consider the full social, environmental and economic context –
how a development integrates into the urban landscape, connects with surrounding
infrastructure, and supports adaptable, high-performance workspaces.

### Decades of experience in the commercial sector

BG&E, acquired by SYSTRA in 2025, brings over 50 years of commercial development
experience. A representative project is Quay Quarter Tower in Sydney’s CBD – a
54-storey vertical village where a simultaneous demolish-and-rebuild and
retain-and-refurbish methodology – one of the earliest applications of this
approach globally – preserved approximately two-thirds of the original
structure, substantially reducing embodied carbon. Other projects in Australia
include Parramatta Square, One The Esplanade and Perth Film Studios.
