Occ. Code 7202130





New York State Department of Civil Service


Classification Standard




            A Maintenance Assistant (Mason and Plasterer) performs semiskilled masonry and plastering work in the construction and repair of buildings and structures, including the use of a variety of masonry materials including brick, stone, plaster and concrete.


            Maintenance Assistants (Mason and Plasterer) are employed by several agencies with the greatest number in the Office of Mental Health and the State University.




            Maintenance Assistant (Mason and Plasterer), as a semiskilled employee, performs the more routine repetitive maintenance and repair tasks in the masonry and plastering trades typically under the supervision of a Mason and Plasterer. Incumbents, in learning and perfecting their craft skills, may perform journey level activities under supervision or after receiving detailed instructions. Incumbents may function as a lead worker on a project basis over maintenance helpers, laborers and other relatively unskilled workers in performing manual tasks involving elementary skills.


            There are a number of other specialized Maintenance Assistant classes having parenthetic designations describing the predominant trade areas in which the incumbent is assigned; i.e., carpenter, plumber and steamfitter, painter and electrician. Although incumbents of such classes may perform tasks normally associated with more than one trade, most of their time is spent performing tasks typical of the trade indicated by the special title.


            Incumbents of Maintenance Assistant positions without a parenthetic designating a trade specialty are usually found in relatively small maintenance staffs where such specialization is not desirable or in maintenance pools where specialization is not efficient. However, incumbents may be assigned to tasks such as those described for any of the specialized positions of Maintenance Assistant.


            Maintenance Assistant is distinguished from Maintenance Helper by the latter's performance of relatively unskilled tasks in direct support of semiskilled or skilled trades positions. Such tasks are performed under very specific instructions and supervision of either a maintenance assistant or a journey level worker.


            The position of Mason and Plasterer is distinguished from Maintenance Assistant (Mason and Plasterer) by the former's responsibility for planning and laying out work on a project basis, and the supervision of a work crew of maintenance assistants, helpers, laborers and occasionally other Mason and Plasterers.

As assigned, a Maintenance Assistant (Mason and Plasterer) functions as a lead worker over a small maintenance crew usually consisting of maintenance helpers and laborers.


Under direction, incumbents may participate in work in other maintenance specialties.




            The nature of Maintenance Assistant (Mason and Plasterer) activities generally restricts relationships to employees working within the same organizational unit. As assigned, incumbents supervise a small maintenance crew characterized by frequent oral communications in assigning work and providing instructions. Written and oral communications with the general public are not typical of this class.




            Maintenance Assistants (Mason and Plasterer) are supervised by skilled craft positions, usually a Mason and Plasterer or a General Mechanic. Work priorities and the nature and extent of work to be performed are prescribed and materials are furnished. When necessary, the work to be performed is laid out by the supervisor who gives specific instructions, assists in the more difficult tasks and inspects the job while in progress and when completed to insure that instructions have been followed and that the quality of the work is satisfactory. However, a Maintenance Assistant may perform the activities of the class with considerable independence when supervision is not immediately available due to such factors as the geographic location of the assignment. In addition, incumbents are expected to perform the more routine repetitive tasks with considerable independence.


            As assigned, a Maintenance Assistant (Mason and Plasterer) supervises a maintenance crew consisting of maintenance helpers, laborers and other relatively unskilled workers by making assignments, giving instructions and providing assistance in performing the work.




            Maintenance Assistants (Mason and Plasterer) use the tools of the masonry and plastering trades, including hand tools such as hammers, floats, trowels, plumb bobs and chisels, and standard measuring instruments such as levels, tape measures and rules and squares, and power tools such as saws for cutting and fitting the masonry materials.
