The new grandstand we are building at Ascot Racecourse is, as your feature suggests (NCE 19 May), an impressive structure. However, some of the figures quoted need correcting.
The main grandstand building will accommodate 45,000 of the 80,000 racegoers at a major event, with the remainder distributed around the various enclosures and other buildings.
The structural floor depth is generally 400mm, not 200mm as stated, and reconfiguration of the stand and parade ring was enabled by moving the western end of the track just 42m north, not 60m, this being the optimum distance to relieve congestion at the venue without losing a sense of bustle and excitement.
Shear cores were cast insitu only up to concourse level, 5m above ground, with precast elements then taking the cores up most of their full 31m height.
The first roof trusses were successfully lifted into position on top of the stability cores on Friday 6 May.
