Get your Preliminary Estimate faster than before!

Preliminary Estimates are used to provide a rough guide as to the cost of the project. Estimates are typically done during a feasibility study, when the project is still in the concept stage. A preliminary estimate has an accuracy of +/- 5% because its based on built-up, averaged prices for similar-type dwellings.

You no longer have to waste hours in your work week calculating estimates yourself, or wait weeks for suppliers to get their quotes back to you. Now you can return a rough, "ball-park" price to your prospective client within days, keeping them engaged and "wowing" them with your speed and professionalism. 

Preliminary Estimates are not something you want to use to go straight to contract with, but they very quickly let you know if it’s in your client’s price range.

How are the costs calculated?

We have access to multiple databases from teams of seasoned construction cost consultants and quantity surveyors. Both the square metre cost and the percentage assigned to each element are based on average prices for typical buildings. However, they are largely determined by the following parameters:

  • Type of building (E.g. project home, individual house, townhouses, apartments etc.)
  • Basic construction material (E.g. framed, brick veneer, full brick etc.)
  • The standard of finish (E.g. basic, medium, high, prestige)  
  • Location of the project (Prices are indexed to the closest capital city and loadings for regional areas, and then applied).
