Existing-condition investigations
Services, substrate, access and retained elements reviewed early enough to influence sequence and procurement.
REFURBISHMENT / BUILDING UPGRADES
Existing buildings.
New performance.
Carefully integrated.
Refurbishment is rarely a clean-slate exercise. Existing fabric, services, tenants, access and unknown conditions all shape how the work needs to be planned.
REFURBISHMENT / BUILDING UPGRADES
Upgrade what exists.
Without losing control of what remains.
O'Neill's approaches refurbishment as an interface problem first. Before finishes are installed, the team needs to understand what is being retained, what is being replaced, how existing services behave and how the building must continue operating around the works.
That means investigations, staging, protection, temporary conditions, procurement and stakeholder communication are treated as core construction activities — not preliminaries that sit outside the programme.
WHAT WE CONTROL
Existing conditions first. Sequence second.
Building upgrades
Common areas, lobbies, amenities, workplace floors and supporting building systems renewed and reconfigured.
Services integration
Mechanical, electrical, fire, hydraulics, security and communications coordinated into existing base-building infrastructure.
Live-building staging
Hoardings, protection, temporary access, isolations and disruptive works planned around building operations.
Fabric & finish interfaces
New finishes resolved against retained walls, floors, ceilings, structure, glazing and existing architectural details.
Commissioning & close-out
Testing, defects, as-builts and handover documentation managed progressively rather than compressed into the final days.
DELIVERY
Investigate. Isolate. Integrate. Handover.
Investigate first
Confirm existing conditions, services, access, retained elements and operational constraints before locking sequence.
Plan temporary conditions
Resolve protection, staging, isolations, egress and building interfaces before disruptive work begins.
Coordinate old and new
Use drawings, RFIs, samples and site set-out to resolve how new work meets existing fabric and systems.
Handover progressively
Commission, inspect, rectify and document as areas complete so practical completion remains controlled.
PROJECT EVIDENCE
Renewal is judged at the interfaces.
CLIENT QUESTIONS
Questions that change the refurbishment strategy.
What is the difference between a commercial fitout and refurbishment?
A fitout usually creates or reconfigures an occupied workplace or tenancy. Refurbishment more often involves significant retained fabric, existing systems, common areas or building-wide interfaces. Many projects contain elements of both.
Can refurbishment work be delivered while a building remains occupied?
Yes, where the project allows it. The methodology needs to address access, protection, noise, dust, services, emergency egress, loading and communication with building management and occupants.
How do you manage unknown existing conditions?
Early investigations reduce uncertainty, but refurbishment still requires clear change control. The key is to identify risk early, keep decision pathways clear and avoid hiding existing-condition issues until they reach a trade on site.
