32 The progress of works was delayed on several occasions, because Metronet's project managers were unaware of documentation required for station access. Prior to planned station works, Metronet routinely approached London Underground informally with queries over documentation. With regards to one specific document, Metronet admitted to being completely unaware of its existence. On another occasion, the London Underground's CPO was not able to answer Metronet's request for assurance, claiming London Underground could not comment because of outstanding documents. There was also confusion between Metronet and its subcontractors on the type of equipment that needed to be used to carry out brick repairs. The Metronet Asset Engineer issued a Prohibition Regulatory Notice to its suppliers due to the unsatisfactory quality of finish.
33 London Underground and Metronet developed a station programme process to be rolled out from May 2006. This planned to cover all aspects of Metronet and London Underground's activities, including interactions around scoping.
