In addition to the full range of normal Quantity Surveying, Bank QS & Project Management services, we can particularly add value in:

  • assisting in initial product typology identification (assisted by the market research report) (e.g. achieved $6mil in additional revenue by adjusting apartment typology),
  • making otherwise unfeasible projects feasible,
  • alternative development Finance options
  • accurate estimating (e.g. estimate within <1.5% of tenders on a 4storey apartment development),
  • achieving substantial Value Engineering savings focused on value, not cost (achieved $2mil savings on a $19mil project),
  • enabling the project to get off the ground, and driving the project forward to ensure it doesn't miss the market.

and the people we help.
