Phases of Building Construction & Establishing Milestones
A construction programme becomes easier to manage when it is divided into defined phases and decision points. Milestones show what must be agreed or completed before the project moves forward.
01 — Initiation and feasibility
The first phase tests the brief against the site, budget, programme and approval pathway. The project team identifies major constraints, considers alternative approaches and defines what information is needed before design progresses.
02 — Planning and design
Architectural, engineering and specialist information is coordinated into a buildable scope. Responsibilities, procurement strategy, cost plan and programme are established, with milestones for client decisions and regulatory submissions.
03 — Procurement and mobilisation
Packages are priced, contractors and suppliers are appointed, long-lead items are identified and the site is prepared for work. Clear release dates protect the programme and reduce uncertainty before major activities begin.
04 — Construction and monitoring
The team delivers the work while tracking progress, cost, quality, safety and changes against the agreed plan. Milestones may include structure completion, building enclosure, services testing and the start of finishes.
05 — Completion and handover
Inspections, testing, defect close-out, cleaning and documentation bring the project to practical completion. A structured handover confirms that outstanding items, operating information and client responsibilities are understood.
