- Units, decimal places, items left unpriced.
What is Cover Pricing?
- When one company finds out what others are pricing their bid and make theirs higher so it isn’t chosen.
- Because there is a belief that if they don’t submit a tender when invited they won’t be asked again.
- Happens in competitive tendering.
What is Front/ Back end loading?
- Costs are applied disproportionally at the start or end of the project to help cash flow.
- The end price of the contract is still the same.
How can the contractor alter their prices to benefit themselves?
-Front end loading
- Back end loading
- Cover pricing
- Contractors will budget for current market prices but will submit a tender with lower prices so they’re chosen. Then they charge the client the actual prices and they have to pay. This must be spotted at tender stage by the client.
What is approach 1 for the correction of errors in tenders?
Tenderer is given the opportunity to confirm or withdraw. If they withdraw, the second best tender is chosen.
What is approach 2 for the correction of errors in tenders?
Tenderer is asked to confirm if errors are to be corrected. If the tender is still the best then errors can be corrected and it is used, if not then the next best tender is checked for errors.
What modifications can be added to a tender so a client accepts it?
Bill of reduction: expensive materials are replaced with cheaper ones and specifications are lowered.
Addenda Bills: Additional works are added to the design as the price quoted was below budget.
