SECTION 2 - SCOPE AND CONTROL OF WORK

CHANGE SUBSECTION 2-1 TO READ:

2-1 AWARD AND EXECUTION OF THE CONTRACT.

2-1.1 City Ordinance. The bidder shall conform to provisions of Ordinance No. 7937 CMS of the City of Oakland, as amended, that may be applicable to its bid or to the contract awarded it.

2-1.2 Approximate Estimate. Unless otherwise specified in the Special Provisions or bid documents as being lump sum items, any quantities given in the specifications, proposal and contract forms are approximate only, being given as a basis for comparing bids. The City of Oakland, does not, expressly or by implication, agree that the actual work amount will correspond therewith, but reserves the right to increase or decrease the amount of any class or portion of the work or to omit portions of the work, as may be deemed necessary or advisable by the Engineer.

2-1.3 Examination of Plans, Specifications, and Site of Work. The bidder shall examine carefully the contemplated work site and the proposal, plans, specifications and contract forms. It will be assumed that the bidder has investigated and is satisfied as to the conditions to be encountered, as to the character, quality, and quantities of work to be performed and materials to be furnished, and as to the requirements of these specifications and the contract. It is mutually agreed that submission of a proposal shall be considered prima facie evidence that the bidder has made such examination.

2-1.4 Proposal Form. All proposals must be made upon forms contained in the proposal section of the bound project documents.

Bids are required for the entire work. The bid amount, for comparison purposes, will be the total of all items. The total of unit basis items will be determined by extension of the item price bid on the basis of the estimated quantity set forth for the item.

The bidder shall set forth for each item of work, in clearly legible figures, an item price and a total price for the item in the respective spaces provided for this purpose. In the case of unit basis items, the amount set forth under the "Total" column shall be the extension of the item price bid on the basis of the estimated quantity.

In case of a discrepancy between the item price and the total set forth for the item, the item price shall prevail. However, if the amount set forth as an item price is ambiguous, unintelligible, or uncertain for any cause, or if omitted, or in the case of unit basis items, is the same amount as the entry on the "Total" column, then the amount set forth in the "Total" column for the items shall prevail in accordance with the following:

1) As to lump sum items, the amount set forth in the "Total" column shall be the item price.

Project Special Provisions for Project No. 1007889 15 Bid Documents: October 7, 2026

2) As to unit basis items, the amount set forth in the "Total" column shall be divided by the estimated quantity for the item and the price thus obtained shall be the item price. All bids shall be clearly and distinctly written. The bidder, who shall fill in all blanks in the proposal forms as therein required, shall sign the proposal.

3) As to add or subtract alternate bids, any discrepancy between the proposal form and changes made by the bidder, the amount shown will be for the alternate as shown on the proposal form.

2-1.5 Bid Security. Each bidder shall submit with the bid security either cash, certified check or cashier's check of or on some responsible United States Bank, in favor of and payable at sight to the City of Oakland, in an amount not less than ten percent (10%) of the base bid amount. The Contractor must use only the City of Oakland bid security form included with the project documents; bid security forms originating from other institutions will not be accepted. Any contractors not complying with this requirement may be determined to be non-responsive/non-responsible bidders.

To be valid, the original copy must be delivered to the City Clerk's Office within 24 hours of the time and date of the bid opening. If the bidder to which the contract is awarded shall, for 20 calendar days after receipt of such contract, fail or neglect to enter into the contract and file the required bonds, the bid security shall be forfeited as liquidated damages. The City Administrator shall draw the money due on such bid security and pay the same or any cash deposited into the City Treasury, and under no circumstances shall it be returned to the defaulting bidder. In lieu of the foregoing, any bid may be accompanied by a surety bond on a forfeiture form supplied by the City of Oakland in said amount furnished by a corporate surety authorized to do a surety business in the State of California, guaranteeing to the City that said bidder will enter into the contract and file the required bonds within said period.

The bidder’s failure to enter into the contract after award will result in damages to the City. Such damages are, and will continue to be, impracticable and extremely difficult to determine.

All bid securities and bid bonds will be returned to the unsuccessful bidders after contract award to the successful bidder. The bid security and bid bond of the successful bidder shall be returned after execution of the contract and deposit of the necessary bonds.

If all the bids are rejected, all bids and bid bonds will be returned to the bidders.

2-1.6 Submission and Opening of Bids. All bids shall be sealed, identified as bids on the envelope, and submitted to the City Clerk at the place and time specified in the public Notice to Bidders. The City Administrator or his/her designated representative will open the bids, in public, at the time and place designated in the Notice to Bidders. Bids received after the specified time shall not be accepted and shall be returned to the bidder unopened.

2-1.7. Rejection of Proposals. Proposals may be rejected if they contain erasures, interlineations, or irregularities of any kind. The Council reserves the right to reject any and all bids. The Council may reject the bid of any party who has been delinquent or unfaithful in any former contract with the City and shall reject all bids other than the lowest responsible regular bid.

More than one proposal from an individual, firm, partnership, corporation or combination thereof under the same or different name will not be considered.

Reasonable grounds for believing that any individual, firm, partnership, corporation or combination thereof has a financial interest in more than one proposal for the work contemplated may cause the rejection of all proposals in which such individual, firm, partnership, corporation or combination thereof is interested. If there is reason for believing that collusion exists among bidders, any or all proposals may be rejected. Proposals in which the prices obviously are unbalanced may be rejected. If all bids are rejected, the Agency may again invite sealed proposals as in the first instance.

2-1.8 Complaints. Any bidder or other interested party desiring to enter a complaint against any part or provision of these specifications or the requirements in bidding must file the same in writing in the Office of the City Clerk not later than five working days preceding the date set for submission of the bids.

2-1.8.1 Protests. Any bidder or other interested party desiring to protest against any party bid must file a written statement with the Office of the City Clerk not later than five (5) working days after the bid opening date.

2-1.8.2 Release From Bid. A bidder shall not be relieved of the bid unless by consent of the City, nor shall any change be made in the bid because of a mistake. A bidder may be relieved of its bid if: a mistake is made;

he or she gave the Contracts and Compliance Unit and the City Clerk notice within five working days after the bid opening of the mistake, specifying in the notice in detail how the mistake occurred; the mistake made the bid materially different than he or she intended it to be; and, the mistake was made in filling out the bid and not due to error in judgment or to carelessness in inspecting the work site, or in reading the plans and specifications.

2-1.9 Award of Contract. The contract award, if made, will be by the Council and will be to the lowest responsible bidder whose proposal complies with all the requirements of the Specifications and Ordinance No.

7937 CMS as amended. If the contract award is made within 90 days from opening of the bids, the Contractor will be required to hold the bid price. If the contract award is made more than 90 days, the contractor has the option to notify the City in writing to withdraw their bid within 5 working days from the contract award date. Otherwise, the contractor must hold the bid price. All bids will be compared on the basis of the Engineer's estimate of quantities of work to be done and/or lump sum bid items. The Council reserves the right to waive any informality or minor irregularity in the bids.

2-1.10 Contract Execution. The contract shall be signed by the successful bidder and returned together with the contract bonds, appropriate insurance documents and a copy of Form DE6 (Quarterly Wage Report) for the prime and subcontractors listed in the bid proposal, within 14 days after the receipt of such contract. If the bidder fails or refuses to enter into the contract to do the work, or fails to provide the contract bonds, appropriate insurance documents and the prime and subcontractor’s Form DE6 (Quarterly Wage Report) as required, then the certified check or bid bond accompanying this bid and the amount herein mentioned shall be forfeited, and/or a fine of $1,000 per day, shall be collected by the City of Oakland and paid into the City Treasury.

"Specialty Items" will be identified by the Agency in the Bid or in the Special Provisions. Where an entire item is subcontracted, the value of work subcontracted will be based on the Contract Unit Price. When a portion of an item is subcontracted, the value of work subcontracted will be based on the estimated percentage of the Contract Unit Price.
