Banksia invites tenders for builders to complete the project. The tendering process takes one month. The successful builder, A1 Contractors, is unable to start work on Banksia's project for a further three months because of other building works that they are involved with. Banksia nevertheless engaged A1. As a result of the building not being completed by the original date, Banksia lost a major tenant who was going to lease an entire floor of the building at a rate of $20 per square metre above the market rate.

Advise Banksia and A1 Contractors of their legal rights.
