A challenging project that required a combination of specialist technology and old school methods won the Hirepool Supreme Award at the Nelson Marlborough Civil Contractors Federation Awards held at Annesbrook Church on Friday night.
The award went to Nelmac for the Suter Art Gallery Landscaping project that was a key element in the $12 million redevelopment of the Nelson’s historic art gallery.
Nelmac designed and installed a new boardwalk through native bush outside the gallery that connects the gallery to the neighbouring Queens Gardens and features the Pastorius Waller International Sculpture Walk.
Although constructing a boardwalk may sound straightforward, Nelmac’s Belinda Reburn and Richard Smethurst say working in a unique environment like the Queens Gardens presented many challenges.
“There was nothing simple about this project,” Belinda says. “We had to work amongst the heritage trees so there were a lot of resource consent conditions around the project.
“The guys were hand-digging around the tree roots to put the board walk in and we were very restricted with what we could do working within the tight confines around the buildings. There were a lot of on-site decisions because we were working in such a sensitive environment – it was a very challenging project.”
Richard says they used small excavators at the start of the project but then had “go back to old school of wheelbarrows and hand-digging” as they worked around the roots of heritage trees.
In some areas, arborists used “hydro-vac equipment” to wash out and vacuum up soil around tree roots so that boardwalk foundations could be installed.
One of the judges, Bruce Taylor says Nelmac did a great job of working in such a restricted workspace under tight resource consent conditions. Bruce encouraged everyone attending Friday’s awards to go to the Suter and wanderer around the boardwalk to see the result of a well-managed project.
The big budget Hynds Projects Award, valued over $1.5million, went to Donaldson Civil Ltd for the Nelson City Council Hampden Street Little Go Stream Upgrade. The $4.7million project involved upgrading
The $4.7 million project involved upgrading stormwater system along Waimea Rd to prevent a repeat of the flooding that hit Nelson College and Rutherford St in 2011.
Donaldson Civil director Gary Donaldson says one of the biggest challenges was managing peak traffic flows while laying the stormwater pipes in the middle of Waimea Rd.
“We looked at the site mid-morning when we were tendering for the contract, so we underestimated the volumes of traffic when everyone’s driving to school and work. We had a 2.5m wide trench in the middle of a 7m wide road, so keeping the guys safe and having two lanes of traffic going was a challenge.”
Despite those challenges, Gary says they finished the project ahead of schedule.
