Article 20. Transit Development Boards of California Public Contract Code >> Division 2. >> Part 3. >> Chapter 1. >> Article 20.

The provisions of this article shall apply to contracts by the San Diego Metropolitan Transit Development Board, as provided for in Division 11 (commencing with Section 120000) of the Public Utilities Code.
(a) Contracts for construction in excess of fifty thousand dollars ($50,000) shall be awarded to the lowest responsible bidder submitting a responsive bid after competitive bidding, except in emergency declared by the vote of two-thirds of the membership of the board. If the expected construction contract exceeds one thousand dollars ($1,000) and does not exceed fifty thousand dollars ($50,000), the board shall seek a minimum of three quotations, either written or oral, that permit prices and other terms to be compared, and the board shall award the contract to the bidder who submitted the lowest quotation.
  (b) If no bids are received, the project may be performed by a negotiated contract.
All bids for construction work shall be presented under sealed cover and shall be accompanied by one of the following forms of bidder's security:
  (a) Cash.
  (b) A cashier's check made payable to the board.
  (c) A certified check made payable to the board.
  (d) A bidder's bond executed by an admitted surety insurer, made payable to the board. Upon an award to the lowest bidder, the security of an unsuccessful bidder shall be returned in a reasonable period of time, but in no event shall that security be held by the board beyond 60 days from the time the award is made.
