Project and Bidding Clarifications A. Remove the term “(Arthurs Ditch)” from Bid Item 201-00000 Clearing and Grubbing. This bridge replacement occurs on the Larimer No. 2 Canal. B. Temporary paving during cold weather months has been specified as being recycled asphalt base in Bid Item 406-00700. Contractor may use HMA, WMA or other APPROVED equal material at no additional cost to the City. Contractor is responsible for maintaining temporary pavement as directed by the project engineer in a manner that provides adequate protection on the bridge deck and a reasonable driving surface. C. Revision to Section 105 HMA Pavement Smoothness does NOT apply to this project. There will be no HRI Category II smoothness requirements. However, all LCUASS asphalt patching standards will be applicable. D. Eliminate the plan note on Sheet 10 of the plans indicating a waterproofing membrane on top of the bridge deck. No waterproofing membrane is required. However, joint wrapping is required and included in the precast box culvert specifications and shown in the detail on Sheet 16 of the plans. E. The City will provide all construction surveying for the project including confirmation of final grades as required by Note 25 on Sheet 27 of the plans. F. The Larimer Canal No. 2 ditch has historically been turned back on for service no sooner than April 15th. However, it is the contractors responsibility to coordinate with the Larimer Canal No. 2 ditch company regarding any conflicts in the construction schedule. G. Because the entire existing bridge is to be demolished under full road closure, no stamped, engineered demolition plan is required for removal of the existing bridge. H. Dewatering – Bid Item 211-03005. The intent of this bid item is for dewatering of storm water runoff and nuisance flows. However, the specification for dewatering does include measures for treatment and or disposal if necessary but not expected. No additional payment for dewatering will be provided so please bid accordingly. I. The City will coordinate and pay for all materials testing required for the project. J. Bid Item 630-70000 – Construction Zone Traffic Control. All construction traffic control devices are inclusive in the Lump Sum bid. A list of devices has been provided on Sheet 26 of the Plans FOR INFORMATION ONLY. Additional devices may be needed and the bid should include temporary barriers as shown on Sheet 15 of the Plans and Phase 2 Notes (Construction Phasing Plan) that will be required for safety during Addendum 1 – 7568 Bryan Ave Bridge Replacement Page 6 of 6 construction. No additional payment will be made for setting, adjusting or relocating barriers to facilitate construction phasing under this Lump Sum pay item. K. Bid Item 630-70000 – Construction Zone Traffic Control. Traffic control management, inspections and flagging are NOT included in the Construction Zone Traffic Control lump sum bid item as written in the specifications. TCM, TCI and Flagging will be measured and paid separately by line items provided in the bid form. L. All removals of concrete and pavement on the slopes of the canal shall be included and paid for by the lump sum bid for removal of the existing bridge. No additional payment will be made for removal of concrete and ditch slope paving. II. Revisions to the Plans/Bid Tab: A. The City is beginning to transition from the use of PG 58-28 asphalt binder to PG 64-22 or the asphalt binder. The two asphalt line items have been adjusted to the following:  Hot Mix Asphalt (Grading S)(75)(PG 64-22)  Hot Mix Asphalt (Grading SG)(75)(PG 64-22) Quantities for the above have not changed. B. A new line item has been added to the project under section 202-04000:  Removal of Existing Bridge 1 LS This line item was inadvertently left out of the bid schedule. Project special specifications are provided. III. Revisions to the Project Contract Documents: A. The following has been added to Section 00520 AGREEMENT  Article 3.3.2(3) – A full road closure for demolition of the existing bridge structure and resetting of the new precast bridge structure is limited to no more than 21 Days. Liquidated Damages in the amount of $2,000 per day will be assessed beyond the 21 Days. The contractor is required to re-open the road to a single travel lane northbound into the park at least 12 feet wide no more than 21 days after full road closure and the single travel lane must remain in place until substantial completion is met at which time Bryan Avenue shall be re-opened to traffic in both directions. The 21 day time count will begin when the road is fully closed for removals and demolition.
