Choose a builder with relevant project experience, suitable licensing, clear communication and a well-defined proposal. Compare scope, exclusions, programme and the people managing the site, as well as the price.
Look for comparable experience
A builder’s experience should suit the project’s scale, complexity and construction method. Renovations can require different skills from building a standard new home. Ask to see relevant work and speak with previous clients about communication, coordination and how issues were resolved. Find out who will actually supervise your site rather than relying only on the person presenting the proposal.
Compare the investment and scope
Your building contract represents a substantial investment in your home and lifestyle. Give each builder the same coordinated drawings, specifications and scope so you can assess what each proposal delivers for that investment. Identify exclusions, provisional allowances, owner-supplied items and assumptions. A price with substantial unresolved allowances may change as selections and site conditions become clearer. Ask how variations are priced and how programme changes are communicated.
Check the appointment details
Confirm the relevant licences and understand the proposed contract, insurance arrangements, payment process and responsibilities. Establish who books inspections, coordinates specialist visits and assembles completion information. Obtain appropriate advice on the contract before signing, particularly where the risk allocation or payment terms are unfamiliar.
Bring the design team into the conversation
A designer can help assess whether a proposal responds to the documented scope and identify questions to resolve. Early builder involvement may also improve buildability and sequencing. Modal can assist with tendering and procurement where agreed as part of our service. The goal is a capable team with a shared understanding of the work, supported by clear documentation and expectations.
