FARMINGTON -- Adding 2 inches of road surface over the length of the 7.2-mile Antelope Island Causeway is going to cost Davis County between $1.1 million and $1.2 million, based on contract bids received Tuesday.
But in case Davis County Public Works doesn't have the funds needed for the project, which it budgeted at about $1 million, it also made the four prequalified contractors submit alternative bids to overlay the causeway with 1 1/2 inches of new surface, which would provide a slight savings to the county.
On Tuesday, the Davis County Commission opened the four bids submitted for the causeway work, with a final contract bid to be awarded at its 10 a.m. Tuesday meeting at the Memorial County Courthouse, 28 E. State St., in Farmington.
Staker Parson Companies of Salt Lake City submitted the apparent low bid of $1,085,775 for the 2-inch overlay, with an optional bid of $839,254 for the 1 1/2-inch overlay.
Before making a decision on the thickness of the overlay, the commission will review the bids and determine the difference in the longevity of the less-costly alternative, Davis County Commissioner Bret Millburn said.
Davis County Public Works Director Kirk Schmalz said he asked bidders to provide the county with elaborate options because county funds are limited.
Schmalz said he would prefer a 2-inch overlay because it has a longer life expectancy.
"The more asphalt you put down, the longer it is going last," he said.
But if the county can't afford that, Schmalz said, the 1 1/2-inch overlay on the causeway provides the county with another option.
Either way, the intent is to complete the roadwork during the upcoming construction season.
"The plan would be to do it this summer," Schmalz said.
