The crew of G-XLAG did not realise that Runway 06L was operating at reduced length due to work-in-progress at its far end, until their aircraft had accelerated to a speed approaching the rotate speed (VR), despite:
• Being in possession of a NOTAM concerning the work-in-progress
• The ATIS broadcast relating to the work-in-progress
• ATC passing information on the takeoff distance available
