Background Information:
The Agreement covers design of both Williston/218 and 63/Ridgeway intersection. The 63/Ridgeway
required extra work that was not anticipated at the time of signing the agreement as listed below:
1- Design changes based on Iowa DOT's review of preliminary plans. Mast arm pole configuration
was changed to keep the existing truss.
2- Additional surveying and design effort was also necessary when it was determined that the
existing roadway culvert to drain the median adjacent to the lengthened northeast-bound US 63
left-turn lane could not be utilized and that two new pipe culverts would need to be jacked under
the southwest-bound lanes of US 63.
3- Pursuant of City's efforts the DOT agreed to undertake construction review and inspection for
this project. This saves the City significant amount of money in engineering services costs. To do
this DOT requires a DOT letting. Changes to plans and specifications format must be done to
accommodate a DOT letting.
