Engineering Excellence Delivered

Overview

Design and certification of a 280m post-tensioned concrete bridge spanning the Brisbane River, connecting northern suburbs to the CBD. Project required innovative foundation solutions due to challenging riverbed conditions.

Key Challenge

Variable subsurface geology and stringent flood immunity requirements necessitated deep piled foundations extending 45m below river level, designed to resist 1-in-500-year flood event loads.

Scope Highlights

• Full structural design and documentation
• Geotechnical investigation coordination
• Construction phase engineering support
• Independent design verification and peer review

Outcomes

Delivered 2 months ahead of schedule with 12% cost savings through optimized prestressing design. Bridge achieved 150-year design life with minimal maintenance requirements.

Overview

Master planning and civil engineering design for a 85-hectare industrial and logistics estate including roads, drainage, services, and environmental management infrastructure.

Key Challenge

Sensitive environmental zone requiring comprehensive stormwater quality treatment and erosion control measures while maintaining development viability and staged construction flexibility.

Scope Highlights

• Site-wide drainage and detention basin design
• 14km of internal road network
• Water, sewer, and electrical reticulation
• Environmental impact assessment and approvals

Outcomes

Approved on first submission with no conditions. Stormwater treatment system exceeded regulatory requirements by 25%, establishing new benchmark for industrial development in Tasmania.

Overview

Mechanical, electrical, fire protection, and medical gas systems design for a new 8-storey clinical services wing including operating theatres, intensive care units, and diagnostic imaging facilities.

Key Challenge

Integration with existing hospital infrastructure while maintaining operational continuity. Critical systems required 100% redundancy and seamless changeover capability during maintenance.

Scope Highlights

• Dual-feed electrical distribution with automatic transfer
• Precision HVAC for operating theatre environments
• Medical gas reticulation and alarm systems
• BMS integration with existing hospital controls

Outcomes

Zero downtime during cutover. Systems achieved 99.98% uptime in first operational year. Energy efficiency measures delivered 38% reduction in HVAC energy consumption versus code baseline.

Overview

Civil design for 42km highway upgrade including realignment, pavement strengthening, bridge replacement, and intersection improvements to improve freight efficiency and safety.

Key Challenge

Maintaining traffic flow during construction on critical freight route while managing environmental constraints including threatened species habitat and cultural heritage sites.

Scope Highlights

• Detailed road geometric and pavement design
• Four bridge replacements including 120m span structure
• Traffic management and staging strategy
• Environmental offset planning and implementation

Outcomes

Project completed without significant traffic delays. Safety improvements resulted in 65% reduction in crash rates in first 12 months post-opening. Environmental offset plantings exceeded required area by 15%.
