PURPOSE: The Department of Labor and Industrial Relations is required to determine the prevailing hourly rate of wages to be paid to each worker engaged in construction on a public works project, relative to the type of work performed by each worker. This rule describes by occupational title the type of work performed in the construction of a public works project in Missouri and sets forth the procedures to be followed in identifying each occupational title utilized on a public works project.

Editor’s Note: The secretary of state has determined that the publication of this rule in its entirety would be unduly cumbersome or expensive. The entire text of the material referenced has been filed with the secretary of state. This material may be found at the Office of the Secretary of State or at the headquarters of the agency and is available to any interested person at a cost established by law.

1. (1) Each occupational title defines by name the type of work performed in the construction of a public works project. The description of work designated for a particular occupational title is not intended to be jurisdictional in scope or nature, and is not to be construed as limiting or prohibiting workers from engaging in construction work falling within several occupational titles.

2. (2) Each occupational title of work description shall be based upon the particular nature of the work performed, with consideration given to those trades, occupations or work generally considered within the construction industry as constituting a distinct classification of work. In determining occupational titles and scope of work definitions, the department shall consider the following:

   1. (A) Collective bargaining agreements;
   2. (B) Dictionary of Occupational Titles, as published by the United States Department of Labor; and
   3. (C) Opinions of experts from organized labor and the opinions of contractors and contractor associations as they relate to the custom and usage applicable to the construction industry in Missouri.

3. (3) Any person wishing to add, delete or modify an occupational title of work description shall submit to the director of the Division of Labor Standards a written request containing the proposed changes. Proposals shall contain the following information:

   1. (A) Occupational title;
   2. (B) A description of the physical duties to be performed by workers under the title;
   3. (C) A copy of any current collective bargaining agreements that are relevant to the proposal, if any;
   4. (D) Evidence of hours worked and wages paid while performing work under the title, including fringe benefits paid, if any;
   5. (E) Identification of the county(ies) where the work was performed;
   6. (F) Evidence that the proposed occupational title of work description is for a type or class of work that is commonly utilized by the construction industry on building or heavy and highway construction projects in Missouri; and
   7. (G) Other information concerning the proposed addition, deletion or modification as the director of the Division of Labor Standards may deem advisable under the circumstances.
4. (4) Interested parties who wish to submit wage information to be used in establishing the prevailing hourly rate of wages for a particular class or type of work are required to identify the work according to the applicable occupational title of work description set forth in this rule. Hours of work reported to the department shall not be used to establish the prevailing hourly rate of wages if the party submitting the hours of work fails to identify the work under one of the occupational titles recognized by this rule.
5. (5) Any question as to the proper classification of work should be resolved before the work in question is commenced. Interested parties are encouraged to contact the Prevailing Wage Section of the Division of Labor Standards for an interpretation of these rules and for a determination of the appropriate occupational title of work description, rela- 8 CSR 30-3

tive to the class or type of work to be performed.

1. (6) The occupational titles and work descriptions for each type or class of work contained herein are valid throughout the entire state of Missouri. Through an objection to a wage order, an interested party may assert that any given description of work, as stated within this rule, does not apply to a specific occupational title(s) and that a different work description should apply to that occupational title(s). The interested party shall have the burden of proving by a preponderance of the evidence the inapplicability of the description of work within that particular occupational title, but shall be afforded the opportunity to do so in a hearing on an objection to the wage order before the Labor and Industrial Relations Commission.
2. (7) Occupational titles of work descriptions may be obtained from the department by written request to the director of the Division of Labor Standards, P.O. Box 449, Jefferson City, MO 65102.
