The McPherson City Commission moved ahead with a contract for the partial reconstruction of the intersection of Maple and Elizabeth Streets Monday, though there was a bit of a caveat.
“The earliest possible start date to coincide with the contractor's schedule was Oct. 1,” McPherson Public Works Director Jeff Woodward said. “Using fly ash, this is pretty late in the season. The project won't be completed until the spring.”
Fly ash is a composite material consisting of an asphalt binder and mineral aggregate. According towww.flyashsustainableresources.com, it reaches its maximum strength more slowly than concrete made with only a portland cement. That is especially true in colder weather.
“They're going to take a look at the long-range forecast, as well as their schedule,” Woodward said. “Certainly if they can't make it by Oct. 1, and it's a little iffy at this point, we will be postponing. So it's the weather in conjunction with their schedule, but we're going to look at it when we get closer to Oct. 1.”
The contract was awarded to APAC-Kansas, Salina Division, for $316,807.20, provided APAC uses the fly ash option. McPherson Mayor Tom Brown wanted to keep the rock and geo-grid option on the table, which carried a price tag of $368,045, just in case they can use that in place of fly ash and get the project underway sooner than the spring.
The commission approved that motion unanimously.
