A. Date of Publication January 2, 2020
B. Definition of Building Construction
For the purposes of Prevailing Wage, the Commissioner of Labor and Industry has determined that building construction
occupations are defined to be those performed by a person engaged in a recognized trade or craft, or any skilled, semi -skilled, or
unskilled manual labor related to the construction, alteration, or repair of a public building or facility, and does not include
engineering, superintendence, management, office or clerical work.
The Administrative Rules of Montana (ARM), 24.17.501(2) — 2(a), states "Building construction projects generally are the
constructions of sheltered enclosures with walk-in access for housing persons, machinery, equipment, or supplies. It includes
all construction ofsuch structures, incidental installation of utilities and equipment, both above and below grade level, as well
as incidental grading, utilities and paving.
Examples of building construction include, but are not limited to, alterations and additions to buildings, apartment buildings (5
stories and above), arenas (closed), auditoriums, automobile parking garages, banks and financial buildings, barracks,
churches, city halls, civic centers, commercial buildings, court houses, detention facilities, dormitories, farm buildings, fire
stations, hospitals, hotels, industrial buildings, institutional buildings, libraries, mausoleums, motels, museums, nursing and
convalescent facilities, office buildings, out-patient clinics, passenger and freight terminal buildings, police stations, post
offices, power plants, prefabricated buildings, remodeling buildings, renovating buildings, repairing buildings, restaurants,
schools, service stations, shopping centers, stores, subway stations, theaters, warehouses, water and sewage treatment plants
(buildings only), etc. "
C. Definition of Public Works Contract
Section 18-2-401(11)(a), MCA defines, "public works contract' as "... a contract for construction services let by the state,
county, municipality, school district, or political subdivision or for nonconstruction services let by the state, county,
municipality, or political subdivision in which the total cost of the contract is in excess of $25, 000... ".
D. Prevailing Wage Schedule
This publication covers only Building Construction occupations and rates. These rates will remain in effect until superseded by
a more current publication. Current prevailing wage rate schedules for Heavy Construction, Highway Construction, and
Nonconstruction Services occupations can be found on the internet at www.mtwa eha oubopa com or by contacting the
department at (406) 444-6543.
E. Rates to Use for Projects
ARM, 24.17.127(1)(c), states "The wage rates applicable to a particular public works project are those in effect at the time the
bid specifications are advertised. "
F. Wage Rate Adjustments for Multiyear Contracts
Section 18-2-417, MCA states:
"(I) Arty public works contract that by the terms of the original contract calls for more than 30 months to fully perform must
include a provision to adjust, as provided in subsection (2), the standard prevailing rate of wages to be paid to the workers
performing the contract.
(2) The standard prevailing rate of wages paid to workers under a contract subject to this section must be adjusted 12 months
after the date of the award of the public works contract. The amount of the adjustment must be a 3% increase. The adjustment
must be made and applied every 12 months for the term of the contract.
(3) Any increase in the standard rate ofprevailing wages for workers under this section is the sole responsibility of the
contractor and any subcontractors and not the contracting agency. "
3
G. Fringe Benefits
Section 18-2-412, MCA states:
"(1) To fulfill the obligation ... a contractor or subcontractor may:
(a) pay the amount of fringe benefits and the basic hourly rate of pay that is part of the standard prevailing rate of wages
directly to the worker or employee in cash;
(b) make an irrevocable contribution to a trustee or a third person pursuant to a fringe benefit fund, plan, or program that
meets the requirements of the Employee Retirement Income Security Act of 1974 or that is a bona fide program approved by the
U. S. department of labor; or
(c) make payments using any combination of methods set forth in subsections (1) (a) and (1) (b) so that the aggregate of
payments and contributions is not less than the standard prevailing rate of wages, including fringe benefits and travel
allowances, applicable to the district for the particular type of work being performed.
(2) The fringe benefit fund, plan, or program described in subsection (1)(b) mustprovide benefits to workers or employees for
health care, pensions on retirement or death, life insurance, disability and sickness insurance, or bona fide programs that meet
the requirements of the Employee Retirement Income Security Act of 1974 or that are approved by the U. S. department of
labor. "
Fringe benefits are paid for all hours worked (straight time and overtime hours). However, fringe benefits are not to be
considered a part of the hourly rate of pay for calculating overtime, unless there is a collectively bargained agreement in effect
that specifies otherwise.
H. Prevailing Wage Districts

I Zone Pay
Zone pay is not travel pay. ARM, 24.17.103(24), defines zone pay as "...an amount added to the basepay, the combined sum
then becomes the new base wage rate to be paid for all hours worked on the project. Zone pay must be determined by
measuring the road miles one way over the shortest practical maintained route from the dispatch city to the center of the job. "
See section I above for a list of dispatch cities.
K. Computing Travel Benefits
ARM, 24.17.103(22), states " 'Travel pay, 'also referred to as 'travel allowance, 'is and must be paid for travel both to and
from the job site, except those with special provisions listed under the classification. The rate is determined by measuring the
road miles one direction over the shortestpractical maintained route from the dispatch city or the employee's home, whichever
is closer, to the center of the job. " See section I above for a list of dispatch cities.
L. Per Diem
ARM, 24.17.103(18), states " 'Per diem' typically covers costs associated with board and lodging expenses. Per diem is paid
when an employee is required to work at a location outside the daily commuting distance and is required to stay at that location
overnight or longer. "
M. Apprentices
Wage rates for apprentices registered in approved federal or state apprenticeship programs are contained in those programs.
Additionally, Section 18-2-416(2), MCA states "... The full amount of any applicable fringe benefits must be paid to the
apprentice while the apprentice is working on the public works contract. " Apprentices not registered in approved federal or
state apprenticeship programs will be paid the appropriate journey level prevailing wage rate when working on a public works
contract.
N. Posting Notice of Prevailing Wages
Section 18-2-406, MCA provides that contractors, subcontractors and employers who are "...performing work orproviding
construction services under public works contracts, as provided in this part, shall post in a prominent and accessible site on the
project or staging area, not later than the first day of work and continuing for the entire duration of the project, a legible
statement of all wages and fringe benefits to be paid to the employees. "
O. Employment Preference
Sections 18-2-403 and 18-2-409, MCA requires contractors to give preference to the employment of bona fide Montana
residents in the performance of work on public works contracts.
P. Projects of a Mixed Nature
Section 18-2-408, MCA states:
"(1) The contracting agency shall determine, based on the preponderance of labor hours to be worked, whether the public
works construction services project is classified as a highway construction project, a heavy construction project, or a building
construction project.
(2) Once the project has been classified, employees in each trade classification who are working on that project must be paid at
the rate for that project classification "
Q. Occupations Definitions
You can find definitions for these occupations on the following Bureau of Labor Statistics website:
