Freeway job home stretch stress-filled
Northern Nevada Business Weekly
Norm Bessler has given five years of his life to construction of the I-580 freeway, which runs from Mount Rose Highway to Bowers Mansion in Washoe Valley. Even though the work is nearing completion – the $400 million project is expected to wrap up in the middle of next year – Bessler and other construction managers with general contractor Fisher Industries say the job presents more stress and pressure than ever.
Nearly half of the 8.5-mile freeway has been paved, and crews are pushing hard to lay as much concrete roadway as possible before cold weather stalls work. Coordination and scheduling challenges keep Bessler and project Superintendent Mike Scronce working long hours. Fisher has approximately 155 working days left to complete the job.
With days off due to weather, Fisher expects to wrap up its work in August – but the team isn’t coasting down the backstretch and eyeing the finish line quite yet.
“To me, the finish of a job is the toughest part,” Scronce says. ” It is when you come down to trying to make all the different little fingers of the job come together into one spot. There is a lot to completing this thing, and completing it on time.
“When you start, you have got 1,000 days to get this whole thing built. Now we are down to the end, and before it was this broad spectrum. Now we are here, and the last six months of this thing is going to be the hardest.”
Fisher will be charged a penalty of approximately $42,000 per day for every day it’s over its working allotment of 1,056 days. Bessler says he won’t see the finish line until the roadway is laid.
“We got to get through the weather and get the road covered,” he says. “There’s still a lot of stress. We have got a lot of roadway that is finished, and now we need to cover and seal it.”
Concrete used for the roadway can’t get below 40 degrees for five days once it’s poured, so roadway work effectively will stop soon until the springtime.
“Once it starts freezing at night, the sub-grade freezes and you can’t place new roadway on it,” Bessler says. “That will shut it down. But we are hoping that the first week of November we are still placing finished roadway material.”
Paving challenges aside, Fisher faces an even bigger headache: Removing the concrete arch at the base of the dirt fill used to construct the massive Galena Creek Bridge. Fisher used the large temporary dirt platform to position cranes and falsework for construction of the arched bridge, as well as to haul material to the south end of the job.
Removal of the 12 stories of dirt began on Aug. 15. At the top, the fill over Galena Creek is 220 feet wide. The dirt, nearly 500,000 cubic yards – that’s about 4.5 million wheelbarrow loads – needs to be removed from Galena Canyon, as well as the concrete arch that’s channeled Galena Creek since mid 2008. Bessler says that over the past two years the dirt fill settled just one-quarter of an inch.
“It really held up well through the elements,” he says.
