Having complete knowledge of the measurements taken across the whole 67 acres meant that we have been able to review the totality of the data available and advise where it can be repurposed or updated to meet the requirements, saving multiple surveys of the same area. It also meant that we had a 360° view of what needed to be done, so if our surveyors were unable to access the area they had planned to on their schedule, then they could simply move on to an alternative activity on site rather than have a wasted visit. It helps having been on site so many times over more than a decade, as does knowing all the security staff.

Remaining fleet footed at all times has been key when acting as an information provider to multiple other parties, as any delays in providing the appropriate data can have a significant impact. We know that speed of response is as important as accuracy when, on a development of this scale, holding up a design team could cost in the region of £1m a month.
