Managing the Build and Variations

Effective communication and careful management of changes are essential to keep your project on track and within budget.

Communication and Site Access

Building a home is a collaborative process, but it requires clear boundaries. Your primary point of contact should be the site supervisor, who manages the trades and the schedule. Establish a regular communication routine, such as a weekly phone call or email update, rather than calling daily. While you own the land, the builder has control of the site during construction for safety and insurance reasons. You generally do not have an unrestricted right to enter the site whenever you wish. Most contracts require you to give notice and be accompanied by a builder's representative when visiting the property.

When you do visit the site, be respectful of the trades and the work in progress. If you notice something that looks wrong, do not give instructions directly to the tradespeople. Instead, document your concerns with photos and send them to the site supervisor in writing. This ensures there is a clear trail of communication and that the person responsible for the whole project is aware of the issue. Directly instructing a subcontractor can lead to confusion and may even void parts of your warranty if you interfere with the builder's planned methods.

Managing Changes and Variations

Variations are one of the most common sources of conflict between builders and owners. A variation occurs when there is a change to the scope of work, the materials, or the design after the contract has been signed. In Victoria, the law requires builders to follow a specific process for variations. They must provide you with a written notice that describes the change, the reason for it, and the impact on the price and the timeline. You must sign this notice before the work begins. Avoid making verbal agreements on site, as these are difficult to enforce and often lead to disputes over the final bill.

Some variations are 'builder-led', such as when a specified material is no longer available. Others are 'owner-led', such as when you decide to add more power points or upgrade the flooring. Be aware that builders often charge an administrative fee for processing variations in addition to the cost of the work itself. These fees can range from a few hundred to several thousand dollars. To keep costs down, try to make all your design and material choices before signing the contract. The more changes you make during construction, the more likely you are to experience delays and budget blowouts.

Independent Stage Inspections

While the building surveyor performs mandatory safety inspections, many Victorian buyers choose to hire an independent building inspector for additional quality control. These inspectors look at the build from the owner's perspective, checking for quality of workmanship and adherence to the plans and specifications. They typically inspect at the same stages as the surveyor: base, frame, lockup, fixing, and final. Having an independent set of eyes can identify issues like poorly installed insulation, crooked walls, or sub-standard waterproofing before they are covered up by plaster or tiles.

If your independent inspector identifies defects, you should provide the report to your builder and request that the issues be rectified. A good builder will welcome the feedback as it helps them maintain a high standard of work. However, if a dispute arises, the independent report serves as valuable evidence if you need to escalate the matter to Consumer Affairs Victoria or the Victorian Civil and Administrative Tribunal. Remember that the builder is responsible for fixing defects that do not meet the Australian Standards or the contract requirements. Early detection and rectification are much cheaper than fixing problems after the home is finished.

• Communicate through the site supervisor only
• Request all variations in writing with costs
• Limit changes after the contract is signed
• Schedule independent inspections at each stage
• Keep a log of all site visits and photos
