Pool + Spa Magazine have been following the progress of the development of the new aquatic centre at Hornsby in Sydney's North. In the third part of this feature, demolition of the old pool is complete and construction of the new pool begins. Raymond Huzij, Project Manager, Major Buildings at Hornsby Council talks to Pool + Spa about the team's progress.

P+S: Last time we checked-in, the old swimming pool had just been demolished and the site was being excavated. What stage is the project at now? Has construction of the new pool begun?

Raymond: The main excavation has been completed; foundations have been poured to the western side of the development and a number of columns have been constructed. These columns will support precast beams, which have already been manufactured and are being stored at the fabricator's yard. They are due to be delivered and installed in January.

P+S: How long will this current stage of the construction take and what will the next steps be?

Raymond: Foundations and column construction will continue. Once the precast beams are installed the precast floor planks will go in, which will form the basement floor structure to the western side of the site.

P+S: With the pumps and filtration systems, when will these components be installed?

Raymond: Filtration reticulation system pipework is cast into the pool structure itself - so there is a lot of co-ordination required between the various subcontractors to ensure everything is installed and correctly in place, before the concrete is poured. Retrofitting some pipework or fitting into cast concrete is not feasible. The pumps and their associated reticulation pipework will be installed in the pool plantroom once the pool structure is complete and the plantroom walls have been constructed.

P+S: What will the interior surface of the pool be?

Raymond: All pool interiors will be tiled. The concourse within the pool hall housing, the 25m pool and the leisure pool will also be tiled.

P+S: What are your biggest challenges at this stage of the project and how are you addressing these?

Raymond: The biggest challenge we have had recently was to ensure that the foundations were grounded on solid rock. In some areas this rock was found at deeper levels than anticipated so the sandstone had to be cut away to get the column foundation suitably grounded. We had to get the foundations right as this structure will stand for a minimum of 50 years.

P+S: Is there anything else that you think our readers might like to know about this stage of the project?

Raymond: Hornsby Council and the builders ADCO are striving to their best endeavours to create a facility of the highest quality which the community will be proud of for many years to come. There is a lot of anticipation within the community for the facility to be finally open, with the project still planned for completion in early 2014.
