Construction Phasing
An overview of each phase of a Design and Build Project
Pre-Construction:
From initial enquiry to contract sign off, the Pre-construction phase is the crucial groundwork where we define the scope, costs, and assemble the resources to ensure a smooth construction process.
Construction:
The construction phase is the “building” phase of a project where the plans from design and pre-construction are brought to life. It’s where you see the physical work happening on the site.
Completion:
The completion phase of a building project is the final stage where everything comes together for handover to the owner. It’s all about ensuring the building is functional, safe, and meets all the agreed-upon standards before the keys are handed over.
Handover:
The handover and sign-off phase of a construction project marks the official transfer of the completed building from the contractor to the owner. It’s essentially the culmination of the entire project, signifying that the owner is now accepting the building and responsibility for its operation and maintenance.
