Clause 1 sets out many of the boilerplate clauses within the Contract and provides a number of definitions which are used thereafter. The Clause has been substantially changed from the Red Book 4th edn with a raft of new clauses added. Sub-Clause 1.3 deals with communications and states that approvals, certificates, consents and determinations shall not be unreasonable withheld or delayed. The assignment provisions in Sub-Clause 1.7 have now changed so that restriction on assignment applies to both the Contractor and Employer. Delayed Drawings and Instructions is dealt with at Sub-Clause 1.9. This was previously dealt with at Clause 6.4 of the Red Book 4th edn and it is unclear why such an important provision has now been rolled up in the General Provisions clause.
