The Partial Completion Form (PCF) was introduced on the London Bridge Station Redevelopment project for when the construction or installation of permanent works had to be delivered over several shifts, leaving the installation in a ‘unfinished and safe’ state.
The PCF enabled delivery teams to provide a programme demonstrating which elements would be worked upon on each shift. At the end of each shift, the Contractors Responsible Engineer signed off the PCF and marked up the progressed achieved – confirming that the installation was safe.
The PCF procedure was introduced on the project following a safety incident involving a partially completed aspect of the platform canopy becoming dislodged during extreme weather conditions. It was initially intended as an occasional use procedure. However, during the finishing stages of the project, primarily architectural finishes and MEP install, it became apparent there were many works in a partial stage in areas potentially open to passengers.
Therefore, from 2017 onwards, the PCF procedure was modified to address this. Works reaching a not wholly complete stage each evening without full and proper assurance could then only be released to public use under an additional, appropriate control measure.
