A contract may require a party giving notice of a claim to specify the contractual or legal basis of that claim in the notice (or the supporting particulars). What if that party states a contractual or legal basis for the claim but later (perhaps with the benefit of additional information or because of advice from its lawyers) changes its mind or wants to include further contractual or legal bases? This was considered by the Hong Kong Court of Appeal in Maeda Corporation and China State Construction Engineering (Hong Kong) Limited v Bauer Hong Kong Limited  HKCA 830. It found that a subcontractor could not change the contractual basis for its claim once the time period for providing such notice had expired. What, if any, impact will this decision have on the FIDIC forms of contract?
The 1999 Clause 20 has now been divided into Clauses 20 and 21 whereby Clause 20 refers to Claims and Clause 21 refers to Disputes and Arbitration. Another main upgrade is that Employer’s Claims now need to follow the same procedure. The main list of Employer’s and Contractor’s Claims is as follows: a. Additional payment; b. Reduction in the Contract Price; c. Extension of the DNP; and d. Extension of time.
