This chapter contains section titled:

  • Where a contractor/subcontractor submits a quotation for extra work which is accepted, is the accepted quotation deemed to include for any resultant delay costs?

  • Can a contractor/subcontractor be forced to carry out a variation after practical completion?

  • Where work is omitted from the contract by way of a variation can a contractor/subcontractor claim for loss of profit?

  • Where work is given to another contractor is there liability to pay loss of profit?

  • Where due to a variation a contractor has to cancel an order for the supply of material can he pass on to the employer a claim received from the supplier for loss of profit?

  • How are ‘fair’ rates defined?

  • When do quantum meruit claims arise and how should they be evaluated?

  • Can the issue of a variation to the work ever have the effect of creating a separate or replacement contract?
