The amount of liquidated damages herein fairly approximates Division’s loss at the time of making of this Agreement;

The amount of liquidated damages fixed herein are fair and reasonable and it approximates to the extent possible the actual loss to Division as a result of any delay on the part of Contractor; and

Division and Contractor are sophisticated parties and negotiated this Agreement at arm’s length.

Now therefore, in consideration of the mutual obligations set forth herein, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows

C) Engineer’s Discussion:

1. Brandon Short, PE from Bolton & Menk (B&M) provided the following project overview:

• A.02 o An existing tile main runs through the site from southwest to northeast. Laterals come from the west, northwest, north, and southeast. All tiles will be removed under the pool. Those from the southwest and west will be daylighted, the one from the southeast will be re-routed, and the two from the north will be left intact but most of the flow will be directed to the wetland.

o The wetland pool will be excavated.

• A.03 o This shows the existing tiles and those that will be removed with the project. The landowner indicated there is a tile intake south of the north-south easement line, on the tile main. There is a tile that connects to the main at that location and comes from the northwest up the hill. This tile will need to be daylighted as well.

o See the notes on this page for removal lengths and intervals.

• B.02: Everything on this sheet (except the cover berm) is included in the outlet structure bid item.

Another sheet will be added by addendum to show the inlet structure.

• D.01: All excavated material will be placed in the spoil pile areas, meeting the requirements listed on this sheet.

• K.01: Seeding areas are approximate, and the actual disturbed area will be seeded and paid for. The pool is not seeded.

• M.01: 15” Dual-Wall CPDT may be plowed-in lined corrugated plastic pipe or it may be dual wall sticks.

• M.02 o 15” Dual-Wall CPDT may be plowed-in lined corrugated plastic pipe or it may be dual wall sticks.

o 12” Dual-Wall HDPE must be sticks (N-12 or equal) with F-2 rock bedding. It may not be plowed due to bury depth. This was mis-stated during the meeting.

o SUDAS F-2 bedding is to the top of the pipe https://help.sos.iowa.gov/node/79 o SUDAS R-1 bedding is to the springline o The cover berm and filling of the low area is paid under the earthfill item.

• M.03: Alignment turn can be achieved with a precast elbow or through flexing the joints if that is achievable.
