Testing prolongs Glasgow science tower closure


GLASGOW'S TROUBLED £8.5M Science Centre Tower has still not been handed over to the client, nine months after its failed main bearings were replaced last year.

Contractor Carillion said this week that the tower is now rotating as it should but admitted that it still has no completion date in view.

'The new bearings are working well, but there is still a lot of testing and adjustment to be done before we can hand it over, ' a spokeswoman said. She 'categorically denied' rumours that the delay was partly caused by weather damage to replacement components left unprotected on site.

Trials have been ongoing since the main roller thrust bearing that originally supported the 450t structure's weight was successfully replaced last September with a plain spherical bearing (NCE 25 September 2003). The failed thrust bearing had allowed the 105m high structure to sink 15mm into its basement pit, jamming the mechanism that ensured the tower could rotate.

Client the Glasgow Science Centre (GSC) said the areas being tested included the fire protection system, communications inside the tower, lighting, the external weather station and the drive motors.

All systems need to be signed off by engineers before the GSC can apply for the necessary entertainment licence.
