Shaw’s Quarry is a 7m deep sand pit situated right in the heart of some of the best farming land around…and that’s exactly how Operations Manager Dave Marinkovich expects it to look once the quarry has reached the end of its operable life.
“It’s very important. It was a working farm prior to being quarried, and that will be the aim once it’s finished, so repatriation is a big part of what we’re doing,” he says.
Initially, the pit was planned for a 15-year operation over approximately 40 hectares but, with an increase in truck movements, it’s now expected the life span will last between 7-10 years before the sand supply has reached its limit and the incoming clean-fill has repatriated the site.
“We still have a limit of 200,000 cube a year which, at the moment, we’re pretty much right on target to meet,” Dave says. “Luckily enough we’re almost matching clean fill in with sand out at the moment.”
Along with ensuring the quality of the clean fill is maintained – which is done through regular and rigorous testing – understanding the volume of fill entering the site is almost as important as measuring the volume of sand going out to construction sites around the region, which is where the Loadscan-supplied LVS-3BMF load volume scanner (LVS) really plays its part.
“We put the Loadscan in because we were after the most simple operation that we could have,” Dave says.
“A lot of the sand that comes out of here is for construction; there’s a lot of land development that’s going on in the Hamilton and Cambridge region at the moment and, obviously, with the quantity surveying that happens around that, a lot of them have big ideas as to how much clean fill needs to come out and also how much sand in.
“They’re obviously not working in weights when they’re doing those sorts of surveys, so it’s a great crossover between what they need and what we put out in terms of looking at volumes rather than weight.”
The block-mounted LVS unit is conveniently situated for trucks leaving the site with sand, as well as those entering with clean fill, with adequate room for trucks to queue if demand is high.
