Status: in_force

(1) Definitions. In this section:

(ae) “Agreement with a labor organization” means any agreement with a labor organization, including a collective bargaining agreement, a project labor agreement, or a community workforce agreement.

(am) “Labor organization” has the meaning given in s. 5.02 (8m) .

(as) “Municipality” means the state or a town, city, village, school district, board of school directors, sewer district, drainage district, technical college district or other public or quasi-public corporation, officer, board or other public body charged with the duty of receiving bids for and awarding any public contracts.

(b) “Person” means an individual, partnership, association, limited liability company, corporation or joint stock company, lessee, trustee or receiver.

(bm) “Political subdivision” means a city, village, town, or county.

(c) “Public contract” means a contract for the construction, execution, repair, remodeling or improvement of a public work or building or for the furnishing of supplies or material of any kind, proposals for which are required to be advertised for by law.

(d) “Subcontractor” means a person whose relationship to the principal contractor is substantially the same as to a part of the work as the latter’s relationship is to the proprietor. A “subcontractor” takes a distinct part of the work in a way that the “subcontractor” does not contemplate doing merely personal service.

(1m) Method of bidding.

(a) Except when necessary to secure federal aid, whenever a political subdivision lets a public contract by bidding, the political subdivision shall comply with all of the following:

1. The bidding shall be on the basis of sealed competitive bids.

2. The contract shall be awarded to the lowest responsible bidder.

(b) Except when necessary to secure federal aid, a political subdivision may not use a bidding method that gives preference based on the geographic location of the bidder or that uses criteria other than the lowest responsible bidder in awarding a contract.

(2) Bidder’s proof of responsibility. A municipality intending to enter into a public contract may, before delivering any form for bid proposals, plans, and specifications to any person, except suppliers, and others not intending to submit a direct bid, require the person to submit a full and complete statement sworn to before an officer authorized by law to administer oaths. The statement shall consist of information relating to financial ability, equipment, experience in the work prescribed in the public contract, and other matters that the municipality requires for the protection and welfare of the public in the performance of a public contract. The statement shall be in writing on a standard form of a questionnaire that is adopted and furnished by the municipality. The statement shall be filed in the manner and place designated by the municipality. The statement shall not be received less than 5 days prior to the time set for the opening of bids. The contents of the statement shall be confidential and may not be disclosed except upon the written order of the person furnishing the statement, for necessary use by the public body in qualifying the person, or in cases of actions against, or by, the person or municipality. The governing body of the municipality or the committee, board, or employee charged with, or delegated by the governing body with, the duty of receiving bids and awarding contracts shall properly evaluate the statement and shall find the maker of the statement either qualified or unqualified.

(3) Proof of responsibility, condition precedent. No bid shall be received from any person who has not submitted the statement as provided in sub. (2) , provided that any prospective bidder who has once qualified to the satisfaction of the municipality, committee, board or employee, and who wishes to become a bidder upon subsequent public contracts under the same jurisdiction, need not separately qualify on each public contract unless required so to do by the municipality, committee, board or employee.

(4) Rejection of bids. If the municipality, committee, board or employee is not satisfied with the sufficiency of the answer contained in the statement provided under sub. (2) , the municipality, committee, board or employee may reject or disregard the bid.

(5) Corrections of errors in bids. If a person submits a bid or proposal for the performance of public work under any public contract to be let by a municipality and the bidder claims that a mistake, omission or error has been made in preparing the bid, the bidder shall, before the bids are opened, make known the fact that an error, omission or mistake has been made. If the bidder makes this fact known, the bid shall be returned to the bidder unopened and the bidder may not bid upon the public contract unless it is readvertised and relet upon the readvertisement. If a bidder makes an error, omission or mistake and discovers it after the bids are opened, the bidder shall immediately and without delay give written notice and make known the fact of the mistake, omission or error which has been committed and submit to the municipality clear and satisfactory evidence of the mistake, omission or error and that it was not caused by any careless act or omission on the bidder’s part in the exercise of ordinary care in examining the plans or specifications and in conforming with the provisions of this section. If the discovery and notice of a mistake, omission or error causes a forfeiture, the bidder may not recover the moneys or certified check forfeited as liquidated damages unless it is proven before a court of competent jurisdiction in an action brought for the recovery of the amount forfeited, that in making the mistake, error or omission the bidder was free from carelessness, negligence or inexcusable neglect.

(6) Separation of contracts; classification of contractors. In public contracts for the construction, repair, remodeling or improvement of a public building or structure, other than highway structures and facilities, a municipality may bid projects based on a single or multiple division of the work. Public contracts shall be awarded according to the division of work selected for bidding. Except as provided in sub. (6m) , the municipality may set out in any public contract reasonable and lawful conditions as to the hours of labor, wages, residence, character and classification of workers to be employed by any contractor, classify contractors as to their financial responsibility, competency and ability to perform work and set up a classified list of contractors. The municipality may reject the bid of any person, if the person has not been classified for the kind or amount of work in the bid.

(6m) Prohibited practices. A municipality may not do any of the following in a specification for bids for a public contract under this section:

(a) Require that a bidder enter into or adhere to an agreement with a labor organization.

(b) Consider as a factor in making an award under this section whether any bidder has or has not entered into an agreement with a labor organization.

(c) Require that a bidder enter into, adhere to, or enforce any agreement that requires, as a condition of employment, that the bidder or bidder’s employees become or remain members of, or be affiliated with, a labor organization or pay any dues, fees, assessments, or other charges or expenses of any kind or amount, or provide anything of value, to a labor organization or a labor organization’s health, welfare, retirement, or other benefit plan or program.

(6s) Protected activity. Nothing in this section prohibits employers or employees from entering into agreements or engaging in any other activity protected by the National Labor Relations Act, 29 USC 151 to 169 .

(7) Bidder’s certificate. When bidding on a public contract, the bidder shall incorporate and make a part of the bidder’s proposal for doing any work or labor or furnishing any material in or about any public work or contract of the municipality a sworn statement by the bidder, or if not an individual by one authorized, that the bidder or authorized person has examined and carefully prepared the proposal from the plans and specifications and has checked the same in detail before submitting the proposal or bid to the municipality. As a part of the proposal, the bidder also shall submit a list of the subcontractors the bidder proposes to contract with and the class of work to be performed by each. In order to qualify for inclusion in the bidder’s list a subcontractor shall first submit a bid in writing, to the general contractor at least 48 hours prior to the time of the bid closing. The list may not be added to or altered without the written consent of the municipality. A proposal of a bidder is not invalid if any subcontractor and the class of work to be performed by the subcontractor has been omitted from a proposal; the omission shall be considered inadvertent or the bidder will perform the work personally.

(8) Settlement of disputes; defaults. Whenever there is a dispute between a contractor or surety or the municipality as to whether there is compliance with the provisions of a public contract as to the hours of labor, wages, residence, character and classification of workers employed by the contractor, the determination of the municipality is final. If a violation of these provisions occurs, the municipality may declare the contract in default and request the surety to perform or relet upon advertisement the remaining portion of the public contract.

(9) Estimates and release of funds.

(a) Notwithstanding sub. (1) (as) , in this subsection, “municipality” does not include the department of transportation.

(b) As the work progresses under a contract involving $1,000 or more for the construction, execution, repair, remodeling or improvement of a public work or building or for the furnishing of supplies or materials, regardless of whether proposals for the contract are required to be advertised by law, the municipality, from time to time, shall grant to the contractor an estimate of the amount and proportionate value of the work done, which entitles the contractor to receive the amount of the estimate, less the retainage, from the proper fund. The retainage shall be an amount equal to not more than 5 percent of the estimate until 50 percent of the work has been completed. At 50 percent completion, further partial payments shall be made in full to the contractor and no additional amounts may be retained unless the architect or engineer certifies that the job is not proceeding satisfactorily, but amounts previously retained shall not be paid to the contractor. At 50 percent completion or any time after 50 percent completion when the progress of the work is not satisfactory, additional amounts may be retained but the total retainage may not be more than 10 percent of the value of the work completed. Upon substantial completion of the work, an amount retained may be paid to the contractor. When the work has been substantially completed except for work which cannot be completed because of weather conditions, lack of materials or other reasons which in the judgment of the municipality are valid reasons for noncompletion, the municipality may make additional payments, retaining at all times an amount sufficient to cover the estimated cost of the work still to be completed or may pay out the entire amount retained and receive from the contractor guarantees in the form of a bond or other collateral sufficient to ensure completion of the job. For the purposes of this section, estimates may include any fabricated or manufactured materials and components specified, previously paid for by the contractor and delivered to the work or properly stored and suitable for incorporation in the work embraced in the contract.

(11) Limitation on performance of private construction work by political subdivisions.

(a) In this subsection, “construction project” means a road, sewer, water, stormwater, wastewater, grading, parking lot, or other infrastructure-related project or the provision of construction-related services for such a project.

(b) Except for work ancillary to replacing a utility-side water service line, as defined in s. 196.372 (1) (c) , containing lead that is performed with the consent of a private property owner and that does not involve replacing the customer-side water service line, as defined in s. 196.372 (1) (a) , containing lead, a political subdivision may not use its own workforce to perform a construction project for which a private person is financially responsible.

(12) Public building plan information.

(a) In this subsection:

1. “Public building plan information” means construction plans, designs, specifications, and related materials for construction work undertaken, or proposed to be undertaken, by a municipality pursuant to a public contract.

2. “Public plan room” means a nonprofit organization that gathers and makes available to the public for inspection and copying public building plan information.

(b) Notwithstanding s. 19.35 (3) , if a municipality receives a request for public building plan information from a public plan room, the municipality shall provide the requested information by electronic copy, and without charging a fee, if all of the following apply:

1. The public building plan information relates to a structure or building constructed, or proposed to be constructed, by a municipality.

2. The public plan room allows the public to register and inspect or copy the public building plan information that it obtains under this subsection without charging a fee.

(c) A municipality shall provide the requested information under par. (b) even if the municipality contracts with another person to assist the municipality with public contracts, related construction projects, or the management and storage of public building plan information.
