How can I control the time duration of the construction period?
Appoint people with sound experience and an excellent reputation in the built industry. Look out for teams with first-rate portfolios covering projects completed and testimonies of clients.
Have a good contract in place. This will integrate penalties as incentive and regulator for the contractor.
All parties have to agree to a reasonable deadline, while taking into consideration all factors that might cause a delay. Get updates on a regular basis and measure progress against the deadlines set.
Establish open communication between all parties. If an issue arises, inform all relevant parties immediately, so that a resolution can be achieved as soon as possible.
Remain conscientious when it comes to drawing sign-off by the client so that the contractor is sure to always have the latest drawings to work from. This will limit misunderstandings between the client, architect and contractor.
Despite the pre-determined project schedule and all the planning that this entails, it is good practice to supplement already built-in project contingencies. As a rule-of-thumb provide three additional months after the planned completion date to provide for possible delays to date earmarked for moving into your new home.
