Warespace Alexandria

The project is being delivered under a Design and Construct (D&C) procurement model, providing a collaborative approach between the developer, design consultants and construction team from the early planning stages through to completion. This delivery method enables buildability reviews, value engineering, programme optimisation and proactive risk management throughout the design process, ensuring cost certainty, quality outcomes and efficient project delivery. Close coordination with consultants, authorities, subcontractors and stakeholders allows design development, procurement and construction activities to progress concurrently, reducing programme risk while maintaining high standards of safety, quality and commercial performance.

Challenges: The success of this project lies not only in the quality of the finished development, but in the engineering decisions made long before construction commenced. Every major project constraint was identified during the planning phase and addressed through innovative design and construction methodologies, allowing the project team to eliminate risk wherever possible rather than simply manage it during construction. The 27–31 Doody Street development presented a highly constrained construction environment requiring innovative engineering and meticulous planning. Key challenges included vibration and noise-sensitive neighbouring properties, potentially contaminated soils, the site's immediate proximity to Alexandria Canal, and a groundwater table located approximately 500 mm below the proposed basement slab that fluctuates with tidal movements and flood events. Additional complexities included restricted site boundaries, limited street frontage, maintaining safe traffic movements within an active industrial precinct, and delivering a premium multi-level industrial workspace development while minimising environmental impacts and disruption to surrounding businesses.Innovations: To overcome these challenges, the project team fundamentally redesigned the construction methodology to remove risk at its source. A G-Pile push piling system was adopted in place of conventional CFA bored piling, virtually eliminating vibration, significantly reducing construction noise, and eliminating the excavation of potentially contaminated spoil typically associated with traditional piling techniques. The basement has been engineered as a fully hydrostatic structure capable of permanently resisting groundwater pressures resulting from tidal fluctuations, with construction undertaken under a carefully managed dewatering system to maintain stability and environmental compliance throughout excavation. Recognising the site's constrained footprint and limited street frontage, construction logistics were also incorporated into the structural design. Temporary manoeuvring areas have been strategically created within the building footprint, allowing articulated semi-trailers to safely enter, turn within the site and exit in a forward direction. This innovative approach eliminates reversing movements onto public roads, improves safety for workers and the public, and significantly enhances site productivity throughout construction.Achievements: The project demonstrates how early contractor involvement, collaborative engineering and proactive risk management can transform complex site constraints into opportunities for innovation. By integrating low-impact foundation systems, hydrostatic basement design, intelligent groundwater management and purpose-designed construction logistics into the delivery strategy, the project has significantly reduced environmental impacts, improved stakeholder outcomes and increased programme certainty. These initiatives have created a safer, quieter and more sustainable construction methodology while maintaining operational efficiency within one of Sydney's most constrained industrial precincts. The project establishes a benchmark for the delivery of complex urban industrial developments, demonstrating how engineering innovation, buildability and strategic planning can deliver outstanding outcomes for clients, neighbouring stakeholders and the wider community.
