  • Revising clauses on novation to include a new definition for contractor/new client, for when the architect/consultant is being novated across to the contractor on a design and build project
  • Removing clause stating that the architect/consultant had to obtain written consent from the client to publish photographs and other information relating to the project (subject to the standard confidentiality conditions)
