Project delays?

With highly transparent cost plans and documentation that can be communicated to trades and suppliers, your project will have a much higher chance of being completed without costly delay. We can point out areas of your build where potential delays can occur to allow for fore sight in the construction timeline.

 

Financial exposure?

Incorrect cost plans and building budgets may affect your construction loan and bank finance capacity. We aim to help minimise this risk by providing highly accurate cost reports based on the latest market rates.
