12th June 2002

The two ride supports were installed, and the concrete roof added above. Station steelwork was erected, with the top platform set to hold the dropping floor. Soil was moved to form a mound against the tunnel wall, and the last few footers were poured.

The maintenance building framework was erected. Tarmac had been poured on the future paths around the site as a temporary surface for construction vehicles. This would eventually be block paved.

3rd August 2002

The lowering station floor arrived and was placed on top of the tunnel roof, alongside station supports.

24th August 2002

Large deliveries of steel started to arrive on 4th August. Much had been erected since then, with the track completed up to the base of the lift. The lowering floor was installed, along with the upper station structure. A second trench had been dug for the water feature under the entrance to the second corkscrew.

The majority of the ride electronics had been installed, ready for commissioning and testing to start at the beginning of December.

As testing commenced, work continued on the ride area and landscaping.

Visible from the Monks Walk footpath was new fencing around the station drop and along the exit path.
