Client: Multiplex / UNSW
Location: Sydney, NSW
Project Value: $5M
Completion: 2018
Sector: University Research Infrastructure

Project Overview

UNSW’s Science & Engineering Building was designed to bring together some of Australia’s most advanced research laboratories under one roof. Delivering eight floors of lab space with highly complex utility requirements demanded a partner capable of handling ultra-high purity systems, hazardous gases, and life safety integration at scale.

Multiplex engaged Umech to provide complete design, installation, and commissioning of laboratory gas infrastructure — ensuring research-ready facilities built to the strictest safety and quality standards.

Umech’s Role

Across the eight-level facility, Umech delivered:

10km of orbitally welded ultra-high purity tube to ensure leak-free, contamination-free performance.
28 specialty gas cabinets and 94 manifold panels for safe, reliable supply of diverse gases.
182 gas sensors integrated into a SIL-rated life safety system for toxic and flammable gas detection.
House gas distribution for nitrogen and compressed air.
Bulk liquid nitrogen plant with vacuum-insulated liquid filling lines.
Specialty gas delivery systems from cylinder sources into individual labs.
Oxygen depletion monitoring and laser safety interlocks to safeguard researchers.
Four dry steam plants and local vacuum systems to support lab operations.
Full site construction management, procurement, supervision, QA, and commissioning.

Technical Highlights

Eight-floor laboratory fit-out with seamless integration into existing UNSW services.
High-purity orbital welding for 99.999% gas purity systems.
Comprehensive life safety coverage with 182 gas sensors monitoring in real time.
Vacuum-insulated cryogenic supply lines for efficient, safe bulk nitrogen delivery.
Cleanroom-compatible installation practices meeting international quality standards.
Close collaboration with Multiplex and UNSW stakeholders to meet strict delivery milestones.

Outcome

The UNSW Science & Engineering Building was delivered on time and to specification, with all systems performing to the highest compliance standards. The facility now enables world-class research across multiple scientific disciplines — powered by Umech’s engineered specialty gas, cryogenic, and life safety systems.
