SPECIFICATIONS 1. The bid opening date has been changed. The bid will be opened on November 12, 2003 at 3:00p.m. (Our Clock). 2. Clarification to Section 01010/1.09, Summary of Work, Regulatory Requirements. Contractor is not responsible for obtaining a 404 permit from the U.S. Army Corps of Engineers (USACE). Owner will obtain the permit and provide a copy to the Contractor. Contractor shall follow any special provisions of the permit. After discussions with the USACE, it is expected that a nationwide permit will be issued for this project. At this time, construction disturbance to the existing sand bar/island near Pier 1 is not expected to be an issue with the USACE. Contractor must restore all disturbance in the channel bed to existing conditions and existing contours. Disturbance area is limited to the City of Fort Collins' property, Lyons Park access, the permanent easement along the south bank of the river, and construction easements on the Hetzel and Delehoy properties. Reference the property ownership figure included with Addendum 1. Contractor shall take care to protect and minimize construction disturbance to the south bank line, which includes sensitive habitat and the Hyde Natural Area. Disturbance on City of Fort Collins property up to the south Delehoy property line is expected for construction of the bank protection. Disturbance within the construction easement shall be minimized to the extent possible. Trees should be protected except those noted for pruning or removal on the Drawings. If special, unforeseen conditions are placed on the Contractor by the USACE through the 404 permit, a change order will be pursued at that time. FEMA did not require any special conditions for the project. Clarification to Section 01010/1.10, Summary of Work, Easements and Rights -of -Way. Reference this section for information regarding limits of construction. Although not shown on the Drawings, minor access may be obtained from the Delehoy's through their pasture to the Hyde Natural Area if the work necessitates it. However, there are numerous trees along the south bank that restrict accessing with large equipment or vehicles to the riverbank and this cannot be considered a primary access. Construction easement has not been obtained across the Delehoy's property at this time, but the Delehoy's have given verbal permission for access. Any disturbance would require restoration back to existing or better conditions. The primary construction access is from two locations: (1) Lyons Park, which provides access to the channel bed. Equipment may be mobilized along the channel bed, but disturbance should be minimized to the extent practicable. Some equipment can cross under the Overland Trail Road bridge on City of Fort Collins property between the bridge's center pier and north abutment. The roadway bridge must be protected. Clearance should be checked for equipment travel under the bridge. (2) The existing driveway onto the Hetzel property off of Overland Trail Road provides access to both City of Fort Collins property and the construction easement near the north abutment. The channel bed can also be accessed via this route. Page 1 of 2 215 North Mason Street • 2nd Floor • P.O. Box 580 • Fort Collins, CO 80522-0580 • (970) 221-6775 • FAX (970) 221-6707 4.
