A typical construction process begins with planning and design. This involves surveys, architectural drawings, engineering assessments, and planning applications. Once approvals are granted, contractors prepare the site by setting up access, utilities, and safety measures. The structural work follows which includes foundations, framing, walls, roofing, and internal systems such as plumbing and electrics. After this, finishing work takes place which includes plastering, flooring, and decoration. The project ends with inspection, testing, snagging, and final handover.
Residential project timelines vary depending on the size and complexity of the build. A standard new build house commonly takes between six and twelve months. Extensions and renovations may take between eight and twenty four weeks depending on structural changes, planning requirements, and access conditions. Delays can occur due to weather, material availability, or unexpected findings during the build.
Key phases include initial consultation, design and planning, approvals, site preparation, structural construction, installation of mechanical and electrical systems, internal finishing, and external landscaping. The final stages include inspections, certification, snagging, and handover. Each phase must be completed to the required standard before moving to the next.
Construction management ensures that the project runs smoothly, safely, and efficiently. Managers coordinate labour, materials, subcontractors, and equipment. They monitor progress, ensure compliance with regulations, oversee safety procedures, and handle communication with the client. Their role helps prevent delays, manage costs, and maintain quality throughout the project.
Budgeting begins with detailed plans and accurate cost estimates for materials, labour, equipment, and professional fees. Contractors often provide itemised quotations. Cost management continues throughout the project through regular monitoring of spending against the budget, approval of variations, and updates to financial forecasts. Clients often include a contingency allowance to cover unexpected issues.
Major risks include unexpected ground conditions, material shortages, design changes, weather delays, and safety incidents. Contractors mitigate these risks through thorough planning, site surveys, reliable suppliers, clear communication, strong safety protocols, and well managed schedules. Risk assessments are carried out at each stage to identify and reduce potential problems.
Planning and scheduling specialists are useful for large, complex, or time sensitive projects. They can be involved from the early design stage to help create realistic timelines, sequence construction tasks, and identify critical activities. Their expertise helps reduce delays, coordinate multiple trades, and ensure efficient use of resources.
Modern methods of construction include modular building, off site manufacturing, panelised systems, and advanced digital planning tools. These methods reduce time spent on site by producing components in controlled environments. They also improve accuracy, reduce waste, and allow contractors to work more efficiently in challenging weather conditions.
Change orders are managed through a formal approval process. When a client requests a change, the contractor assesses the impact on cost, timeline, and materials. A revised quotation or variation order is issued for approval. Once agreed, the change is incorporated into the project schedule. Proper documentation ensures clarity and prevents disputes.
Contractors typically provide regular progress updates, either weekly or biweekly. These updates may include written reports, photographs, site meetings, and discussions about upcoming tasks. Clients should expect clear communication about timelines, risks, and any decisions that need to be made. Good reporting strengthens trust and helps the project run smoothly.
