We advise our clients to maintain a buffer of 20% of the total value of the project to accommodate for escalations stemming from:
 
  • change in design
  • change in basic rates of materials
  • time factors
  • other unforeseen incorporations
Besides the above buffer, any additions or subtractions to the areas defined during the costing stage of the project will have a cost implication, which would have to be borne by the client.
