=== Standard of liability ===
*A guarantee of ‘fitness for purpose’ will fairly readily be implied into a design and build package deal contract
*Under such a contract the contractor will be strictly liable to the client for any defect resulting from an error of design
*If the design has not been carried out in-house by the main contractor, but has been subcontracted to either an architect or a specialist sub-contractor, the main contractor will seek to pass liability down the line to the actual designer
*This can only be done if the designer’s liability on the sub-contract is at the same level as the contractor’s liability on the main contract
*While it may be easy for a court to imply the higher standard of obligation into a package deal contract, this cannot override any contrary express terms
*It should be noted that both JCT CD 98 and JCT CDPS 98 make it clear that the main contractor’s liability goes no further than that which would be incurred by an architect or other appropriate professional designer holding himself as competent to take on work for such design
