Specifications include, but are not limited to: Tile crossings on IA 1 All labor, equipment and materials necessary for the two tile crossings needed under IA 1 near station 516+75 and 520+00 or approximately 2.25 miles south of Washington, IA. The farmer that owns the ground on the west side of the highway would like to tile the field and connect the tile to his field on the east side of the highway which outlets into a draw further to the south and east into a natural waterway. It is estimated that the crossing length would be approximately 136' and 130', respectively both at 90 degrees to the roadway. It is estimated that approximately 70’ at each location needs bored and the remainder could be open cut. The existing tile crossing near location Sta. 520+00 that is showing signs of collapsing would get abandoned. Tile crossings on IA 22 All labor, equipment and materials necessary for two tile crossings needed under IA 22 near station 364+25 and station 374+00 or approximately 2.5 miles east of Kinross, IA. The farmer that owns the ground on the west side of the highway would like to tile the field and connect the tile to his field on the east side of the highway which outlets into a draw further to the south and east into a natural waterway. It is estimated that the crossing length would be approximately 100' at each location 90 degrees to the roadway. It is estimated that approximately 50’ at each location needs bored and the remainder could be open cut. One crossing will be located at Sta. 364+25 approximately 25 feet south of the culvert at station 364+50. The other crossing will be located at Sta. 374+00 approximately 35 feet north of the culvert at Sta. 373+65.
