Bayswater Power Station – Cooling Tower 4 Repair

Description: 

The Bayswater Power Station Unit 1 cooling tower was built circa 1982. Its main purpose is to reduce the temperature of the hot working water used to generate electricity via the turbines. The temperature of the working water can reach 100oC. There are three other similar cooling towers within the Bayswater Power Station. Freyssinet Australia was engaged to complete the concrete defect survey and concrete repair on the feedwater culvert running diametrically across the Cooling Tower Unit 4. Freyssinet Australia was also engaged to complete the concrete defect survey of all external shell columns and lintels.

 

Key Aspects: 
Freyssinet’s role was to provide AGL Macquarie with a specialist team to complete concrete repair works to the feedwater culvert. Works included:
Installation of suspended platform and scaffold access
Hydro-demolition of defective concrete (11m3)
Installation of additional reinforcement within concrete (264lm)
Gunite application (11m3)
Removal of scaffold
Site demobilisation
The project was completed during a 20-day shutdown, working day and night shifts in confined conditions.
