Bidders shall acknowledge the receipt of this addendum through the QuestCDN VBid electronic bidding portal in order to submit bid. Please also reference the Project Q&A inside QuestCDN for additional information. General Information: Modifications will be bolded and highlighted in yellow in this addendum for clarification of required changes. A general description of the required changes is provided below, with the specific changes for the individual sections following the general description: Certified Bid Form • This form is utilized to document the approved and awarded bid for the project and should reflect the descriptions, quantities, and units in the QuestCDN Vbid electronic bid form. However, inconsistencies have been identified between the Certified Bid Form, Measurement and Payment, and the electronic bid Form. • Bidders should note that the Table of Contents for the Project will be corrected to include any new sections following bid award. • Bidders should note that the Certified Bid Form will be updated and corrected to match the electronic bid form following the bid award and will not be corrected as part of this addendum as it has no impact on the bid. • Bidders should use the Electronic Bid form on QuestCDN Vbid. Only electronic bids will be received and any hard copy bids delivered, will be rejected. Page 2 of 3 Measurement and Payment • Item Descriptions did not align with the bid form. Corrections have been made in the Bid Form on QuestCDN Vbid. • Some work items were covered by duplicate bid items. To remove confusion the following items were removed from the bid form and the Measurement and Payment: o 16” FM Connection o 18” Gravity Main Connection • Lift Station – Civil / Site Work was modified to include all of the civil work north of Stillwater River. As such the quantity of 10” FM was reduced to only include the work in the highway right- of-way to the south of the Stillwater River crossing. This addendum also includes clarification of pipe material types. • Lift Station – Mechanical was modified to clarify pipe material type inside and under the lift station building. • Gas Service Re-Routing was modified to Gas Service Abandonment. The existing generator on the site will be replaced with a diesel generator, so the gas service to the site will no longer be necessary. Please see the updated description in the Measurement and Payment section. • Electrical Re-Routing was modified to include temporary electrical service to be provided to the existing lift station throughout construction. The intent is to have backup power provided to the existing lift station until the new lift station is in use. • 10” Force Main Connection was modified to include capping of existing piping abandoned in place. • Quality Control Testing is the responsibility of the Contractor per Section 01400 of the Project Manual. As requested by bidders, the Quality Control Testing for the project was added as a separate bid item. This change requires an edit of Section 01400 which is also addressed by this Addendum. Contractor Quality Control and Owner Quality Assurance • This section was modified from making the quality control efforts subsidiary to other items to providing a bid item for Quality Control Testing. Painting • A new section was added to the project manual to cover general painting requirements for the project. Cast-in-Place Concrete • This section was modified to allow ¾” maximum aggregate size. Page 3 of 3 Section Specific Changes: Section 01150 – Measurement and Payment – Delete the full section and replace it with the Measurement and Payment attached to this addendum. Section 01400 – Contractor Quality Control and Owner Quality Assurance – Delete Sections 4.1 and 4.2 and replace with the following: A. See Section 01150 for Quality Control Testing. Section 09900 – Painting – Insert the new specification attached to this addendum. Section 03 30 00 – Cast-in-Place Concrete – Modify Section 2.8 – CONCRETE MIX DESIGN – Subsection F.7 – by deleting “5/8 inch” and replacing it with “3/4 inch”.
