Two Builders, one construction management platform

How Kapitol Group and Multiplex Use Visibuild to Ensure Seamless Quality Assurance Across Every Stage of the 435 Bourke Street Project

435 Bourke Street stands as a blueprint for quality-focused construction — delivered through a single, shared digital system.

Both Kapitol Group and Multiplex — two of Australia’s Top 50 builders — are playing major roles in the project’s success. From early works and demolition to final fit-out of the Commonwealth Bank workplace, each phase has been supported by Visibuild’s powerful construction management platform.

One Billion Dollar Project. Two Builders. Zero Quality Gaps.

Complex builds often suffer from handover friction between contractors. But at 435 Bourke Street, the transition from Kapitol Group to Multiplex has been smooth — thanks to a shared commitment to digital quality management.

• Kapitol Group led early works and demolition
• Multiplex is delivering the structure and fit-out
• Both teams used Visibuild to manage quality workflows and documentation from the outset

This unified approach has ensured consistent QA standards, traceability, and seamless handover documentation.

8,000+ Quality Records Logged Before Vertical Works Began

During the early phase, Kapitol Group captured over 8,000 quality records in Visibuild — covering in-ground services, piling, and concrete slabs.

This critical QA data was handed over directly to Multiplex, providing a complete digital record of completed inspections and open actions. The transition has empowered Multiplex to continue the project with full visibility and no data gaps.

Multiplex Builds Forward with Real-Time Insights

With the structure progressing and the Commonwealth Bank workplace fit-out underway, Multiplex is leveraging Visibuild to:

• Monitor QA workflows across all trades
• Identify areas requiring attention and ensure issue resolution
• Ensure ongoing regulatory compliance
• Enable real-time coordination with subcontractors and Cbus Property

Visibuild’s user-friendly interface and mobile apps make it easy for site and office teams to track progress and maintain quality at scale.

From Demolition to Delivery: Digital QA at Every Stage

Visibuild has supported the project through all phases — not just defect lists, but full-scale quality assurance QA. The platform enables:

• Live quality inspections and approvals
• Centralised defect tracking
• Auditable QA workflows linked to floor plans, zones, and asset IDs
• Transparent reporting for internal and client-side teams

It’s a smarter, more efficient way to manage QA, helping teams build it right — and keep it right — the first time.

46 Stakeholders, One QA Ecosystem

With 46 companies engaged on-site — including trades, consultants, and the client — Visibuild connects all contributors to a single source of truth.

Project teams benefit from:

• Transparent communication across the entire supply chain
• Reduced duplication in QA and compliance workflows
• Shared access to records and approvals
• Central visibility for quality across multiple teams and disciplines

This collaboration-first model supports higher quality outcomes, clearer accountability, and faster issue resolution.

• 6 Star NABERS Energy rating
• Platinum WELL Certification
• Targeting net zero carbon in operation, supported by a solar skin façade and off-site renewables
• First construction site in Victoria to use HVO100 renewable diesel, reducing emissions by up to 90%
