CHARLES CITY — City leaders want to have two bridge designs in hand when considering how to replace the crumbling Charley Western Trail Bridge.
In a revised agreement with the engineering firm hired to inspect the bridge before it began to sag, the city is plans to order one design to accommodate only a recreational trail and a second design of a bridge able to carry a roadway and a recreational trail.
The Charles City Council will review the revised bridge evaluation agreement approved April 3 as well as a second agreement for demolition preparation services with Calhoun Burns and Associates at its planning meeting that begins at 6 p.m. tonight (May 10) in City Hall.
The fee for the revised agreement will be reduced $2,435 from the original fee of $9,770, and the new lump sum fee is $7,335, City Administrator Steve Diers wrote in a memo to the council.
The estimated cost of demolition preparations is $27,225, plus services during the demolition, Diers wrote.
That estimate breaks down like this:
- $1,930 for field investigation and office review,
- $14,625 for demolition design plans and specifications,
- $6,985 for administration and coordination of Iowa DNR and US Army Corps permits,
- $1,000 for asbestos sampling and testing, and
- $2,685 for limited bid phase services.
Calhoun, Burns and Associates will provide coordination and construction administration services during the actual bridge demolition. The price of those services will be negotiated following the bid opening as a supplemental agreement.
