Water project a multi-site challenge
Work is progressing on the Waikato District Reservoir project, which will see the completion of four steel potable water reservoirs at Huntly, Hopuhopu, Pokeno and Ngaruawahia.
Each of the reservoirs will be plumbed into the adjacent existing water networks, with a booster pump station to be constructed at the Central Districts site at Ngaruawahia.
Head contractor Spartan Construction has been working on the project, which is estimated to take around a year to complete.
Spartan Construction project manager Jonathan Chandler says working across four sites simultaneously has required high levels of project management and flexibility to work in with the client’s requirements and weather, which at times has been challenging due to a wet summer.
He says Spartan’s strength is the reputation and experience it has in-house from both directors and its team of staff, which offers clients a great deal of engineering and construction knowledge.
He says that this enables the company to look at different and more innovative ways of doing things often providing a more robust and more cost effective solution.
For example, on this project variable ground conditions has been the biggest challenge and substantial work has been required to provide a suitable platform for the massive tanks which weigh up to four thousand tonnes when full of water.
On two of the sites this involved having to dig into the area which the tanks will sit on top of, remove unsuitable subgrade material and then replace it.
Jonathan says that instead of bringing in new backfill material Spartan recommended re-using the material that was removed then re-compacting it to provide the correct platform for the tank to sit on.
This saved the client considerable time and money, he says.
Spartan has between 10-20 staff and contractors working on the project at any one time and Spartan site supervisor, Karl Kavanagh, has been instrumental in the smooth flow of the project.
Jonathan also cites good relations with key subcontractors, such as Reliant Solutions, which is installing the tanks, as being a key aspect of the success of the project.
“We haven’t worked with them previously but have found the relationship has developed quickly as we have been able to rely on them, which has been really important, especially working across a number of sites,” he says.
The project is due for completion at the end of October and is indicative of the importance the company places on establishing good relationships with all those involved in a project, says Jonathan.
“We work to our clients’ requirements and specifications, aiming to be flexible to meet their needs.
In this case we mobilized to sites as required, working in as part of the greater team to lead the project to a successful result.”
Based in Hamilton Spartan Construction was started over ten years ago to undertake difficult civil construction project, in particular those that are multidisciplinary by nature.
The company has since developed a reputation for relentless and continuous improvement alongside developing strong relationships based on integrity, performance and win-win outcomes.
“Spartan adopts a collaborative approach to contracting where there is a free flow of communication between the parties in a no-blame culture. Stakeholders are encouraged to make best for project decisions and serious disputes are avoided through a ‘fix the problem’ approach versus ‘fix the blame’.
This approach has stood the company in good stead securing a steady flow of work.” He says this is complemented by the Spartan Construction culture, which he defines as a learning culture within which quality systems form a strong base.
Our employees are trained in quality techniques at both office and site level so as to provide a seamless communication of design and construction objectives and provide essen“tial feedback for review and continuous improvement of systems,” he says.
Other projects recently completed by Spartan Construction include the civil works for stage one of the Templeview redevelopment for client the Church of the Latter-day Saints; Mt Misery Reservoir project for the Matamata-Piako District Council; Mapara water supply pumping station and pipeline upgrade for Taupo District Council and civil works for stage 1b of Northgate Business Park development..
