NZCN: Leaving the competition in the dust
Anyone who has worked on property in Canterbury knows that dust can be a huge issue. It causes time, cost and resource delays to the project, not to mention the inconvenience for the local community.
To combat these site conditions, we're trialling two innovative dust management systems at our Beaumont Park development in popular Rolleston.
Featured this month in NZ Construction News, our senior project manager Guy Rodger, talks about the systems and how they are keeping the development moving along successfully.
Here's an extract from the article, and if you'd like the full story, grab a copy of the latest issue of NZ Construction News.
Hot and dry climate creates site challenges
Mr Rodger says that one of the key differences McConnell has experienced working on the Canterbury site is the climatic conditions.
“In the upper North Island, while dust is a factor, rain and the subsequent mud is frequently an issue. Here in Rolleston the recent hot, dry and windy weather combined with unique soil types has certainly led to challenges in managing the dust.
“However, we always look for opportunities to excel and the dusty conditions have led us to support our contractors (Harker Underground and Schick Contractors) with the introduction of dust management initiatives.
“One initiative is an irrigation / dust management system that uses technology to respond remotely to wind and other climatic variables. The other innovation is the trial of polymer additives to the soils which aims to help foster grass growth through soil moisture retention while suppressing dust at the same time.”
Mr Rodger says Environment Canterbury (ECAN) has been supportive of the trials and is monitoring results closely. He says the later product has been particularly useful in stabilising areas not easily accessed with the irrigation method.
“While this may seem like a pretty simple process, anyone who’s worked on or lived beside a dusty site can appreciate the complications the conditions can present. The key benefits we’ve seen flow on from the initiatives are that we are operating with a more efficient and compliant process and we can get on with delivering the project knowing the dust is under control.”
Keeping projects moving ahead despite site challenges
Mr Rodger says; “With our Environmental Consultant Blair Gray, we’ve worked closely with Environment Canterbury for Beaumont Park. Being such a dust-prone area, there are several environmental issues that need to be considered and planned for – not least being the impact on surrounding residents.
“Delivering within the timeframes and the budget has been challenging at times, but through our team we’ve taken a proactive and collaborative approach in working with Selwyn Council, Environment Canterbury, Davey Lovell Smith, Harker Underground, Schick Contractors and Xteriorscapes. Through that approach we’ve been able to focus on delivering a well-planned and carefully delivered project.
“The Christchurch International Airport is about 20 minutes away from the site, but as Cantabrian readers will confirm, Christchurch can become a dust bomb particularly in the Nor West winds so we’ve had to be very conscious of Beaumont Park’s proximity to the airport.”
