The Power Station Project has been in progress for 13 1/2 months. Demolition of the equipment and structures inside the Turbine Hall is complete and all five boilers have been cut into pieces and dropped to grade. Approximately 8,000 tonnes of scrap steel has been sold and removed from site with an estimated 15,000 tonnes of steel remaining.
On arrival and assembly of the 550 tonne mobile crane in February, (largest mobile crane in New Zealand) demolition of the Boiler House superstructure commenced. To ensure the safety of this phase of work that involves heavy lifts and working at heights, a comprehensive demolition methodology was developed by Nikau and approved by WorleyParsons. In addition, each lift has a detailed lift plan developed and all plans are individually reviewed and approved.
To keep the safety focus high we are continuing with tool box talks, hazard IDs, behavioural safety observations and we have introduced a new initiative called practical hazard spot scenarios. These scenarios are set up by the safety personnel and team members are asked to identify the hazards. Two of these have been completed to date (one lifting/rigging and one gas cutting) with a third planned immediately following the Easter break. The feedback from them is excellent with everyone both enjoying and learning from them.
