A sub-contractor has secured a contract for an apartment building comprising 70 apartment
units. Each unit has two appliances each with a weight of 300 kilograms. One morning the site
foreman tells the sub-contractor that all of the appliances are to be altered from floor mounted to
wall mounted. He tells the sub-contractor that he will authorise the variation and the work can be
done on a cost-plus basis. He asks the sub-contractor to begin the work immediately.
Your answer must only consider contract and consent implications.

(a) Detail what implications the variation raises in terms of the existing plan and consent.

(b) Explain how the sub-contractor should respond to the foreman.

(c) Explain what consent and contractual processes, if any, are required.
