Liquidated damages will start on October 31, 2020. There shall be no change in contract price for this item. 2. Due to the unknown foreign gas main and existing easement, the construction plans have been revised to accommodate the foreign gas main and other existing utilities. The change involved moving the sectionalizing valve setting and the regulator station further to the east within the same site footprint. This resulted in changing the connection of the 4-inch upstream from the middle of the underground header to the east regulator run. Waukee will provide additional pipe as needed. No other additional materials are required. Please refer to the attached revised construction plans. Also attached to this letter are a site plan and five cross-sections through the site. This is for information only and shall not be considered part of the construction plans. This is merely additional information for your use should you choose to use them. If site conditions allow, the horizontal 3R elbow at each riser may be eliminated and the horizontal run of the pipe can be aligned with the vertical riser with one vertical 3R elbow. These drawings depict the existing ground profile along with proposed elevations.
