. (a) The board shall afford all bidders an opportunity to
examine the plans, specifications, and working details, and shall
award the contract to the lowest responsible bidder. The board may
provide by resolution that the bids be opened, examined, and declared
by an officer designated in the resolution. The resolution shall
require that the bids be opened at a public meeting called by the
officer and that the results of the bidding be reported to the board
at a subsequent regular board meeting. The notice inviting bids shall
state the time and place of the public meeting and the name of the
designated officer.
(b) 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:
(1) Cash.
(2) A cashier's check made payable to the county.
(3) A certified check made payable to the county.
(4) A bidder's bond executed by an admitted surety insurer, made
payable to the county.
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 county beyond 60
days from the time the award is made.
(c) The person to whom the contract is awarded shall execute a
bond, approved by the board, for the faithful performance of the
contract. The person shall perform the work in accordance with the
plans, specifications, and working details, unless all or any of them
are modified by a four-fifths vote of the members of the board. In
that case, if the cost of the work is reduced by reason of the
modification, the person to whom the contract is awarded shall make
an allowance on the contract price to the extent of the reduction.

percent of the amount of the cost of the original contract.
(3) For contracts whose original cost is two hundred fifty
thousand dollars ($250,000) or more, the amount of the change or
