Village Drive Culvert Replacement Addendum #1 Issued: June 14, 2018 To: All Planholders of Record This Addendum modifies the bid documents as noted below. Acknowledge receipt of the Addendum on the Bid Form. Failure to do so may subject the bidder to disqualification. A. See attached mandatory pre-bid meeting sign-in sheet, agenda and minutes including questions asked during the meeting and official responses/clarification to those questions. B. The following is a list of questions and responses that were received during the Addendum period: 1. No additional questions were submitted during the Addendum period C. Additional Clarifications to Bid Documents: 1. Removal of the existing 60-inch corrugated metal pipe includes removal of any existing concrete surrounding the culvert. In 2016 the City hired a contractor to pump concrete into the deteriorated invert of the existing pipe. The contractor estimates approximately 8-10 yards of concrete was pumped into the invert of the existing culvert to fill in voids in the corroded metal. In addition, there could be remnants of existing headwalls that are buried on the up and down stream ends of the existing culvert. While this has not been verified for a fact there was evidence of formed concrete mass when potholing was completed on the upstream side of the culvert. If headwalls are found it is assumed that those will be within the excavation limits for the new box culvert so the digging extents should not be increased, however, additional effort may be required to remove and dispose of those structures. All costs associated with removal and disposal of the existing 60-inch culvert (including any existing concrete and buried headwalls) shall be included in the linear foot cost under Bid Item No.10. The description of this bid item has also been revised as part of this addendum – see attached revised Bid Schedule. 2. The project manager made an incorrect statement during the mandatory pre-bid meeting and this addendum shall correct that statement. Section 5.0 of the Special Provisions as written stipulates that the Contractor must work in sequential working days (except holidays) to complete the work in a continuous fashion. The work is estimated to take 60 calendar days to complete. The anticipated construction window for this project is July 27, 2018 (once under contract and a notice-to-proceed has been issued) to November 1, 2018 for culvert installation and roadway paving completion, and November 21, 2018 for 137 10th Street, P.O. Box 775088, Steamboat Springs, Colorado 80477-5088 (970) 879-2060 ● Fax (970) 879-8851 ● www.steamboatsprings.net Page 1 of 3 the rest of the project to be substantially completed. For bidding purposes the Contractors shall assume that the liquidated damages will be based on a 60 calendar day project. This duration will be confirmed following the bid with the winning contractor. 3. Additional technical specifications have been included in the Standard Specifications for this project that are not applicable to the work associated with this project. Please disregard those sections that are not relevant to this project. These sections will be removed from the contract documents to avoid any confusion. 4. Wetland Permitting Update: The wetlands permit has been secured from the Army Corps of Engineers. See attached copy of the City’s Pre-Construction Notification (PCN) report prepared by Western Bionomics, Inc. dated April 3, 2018 and the Army Corps of Engineer’s Nationwide Permit authorization letter dated May 24, 2018. The Contractor will be required to adhere to all requirements of this permit. 5. The Tabulation of Length & Design Data shown on the cover sheet of the plan set is hereby revised with the following station information: Begin Project: STA. 100 + 00 End Project: STA. 100 + 50.43 6. There are two known existing gas mains crossing the existing/new culvert on the upstream (eastern) side but only one (1) of those mains is suspected to require relocation. See Section 18.0 of the Special Provisions for more information regarding the one gas main that is suspected to require relocation. 7. The City has been notified that there is a Resort Internet fiber optic cable running above the Centurylink concrete duct bank as shown on sheet 8 in the plans. These fiber optic cables, and the other utilities in this immediate area at the downstream end, are not believed to require any relocation. See Section 18.0 of the Special Provisions for more information regarding utility relocations. 8. The City has hired Layne INLINER to line an existing culvert crossing under Village Drive at Medicine Springs Drive. This is another project in the immediate vicinity that was not explicitly included in Section 9.0 of the Special Provisions. The work is tentatively scheduled for August or September 2018 and that work is not believed to require a roadway closure at that location, however, the Contractor is hereby put on notice coordination with this adjacent project may be required. If the road does need to be closed at Medicine Springs Dr. by Layne INLINER and the Village Drive at Burgess Creek construction contractor is using Medicine Springs Drive as their detour route around the road closure then they may need to modify their traffic controls during this time. The City’s project manager for both of these projects is Danny Paul. 9. A preliminary construction schedule identifying start/end dates, major construction work tasks and associated milestones, identification of start and end points, and project completion shall be submitted with the Contractor’s bid. 137 10th Street, P.O.
