WATER SYSTEMS CONSTRUCTION DESIGNER
DISTINGUISHING FEATURES OF THE CLASS
The work involves responsibility for the design and layout of the routes of water transmission and distribution lines and appurtenances under general supervision. The design aspect of this work means determining sizes of water mains, kinds and sizes of fittings, and number of fire hydrants to be used to build or extend water transmissions, or distribution lines. The work also includes design and layout of meter pits, valve pits and chlorine booster and corrosion control facilities. The layout aspect of this system means physically plotting on either side of a street and in relation to underground facilities and above ground obstructions, the route of the system. An employee in this class receives assignments both orally and in a written format from their supervisor who may use narrative, graphic, or numeric materials to introduce new assignments. Design and layout assignments fall into these categories: tract jobs, which involve constructing water distribution systems in proposed housing developments; system betterment jobs, which involve replacing existing distribution system with larger size mains; and new area jobs, which involve constructing transmission lines where none had existed. The scope of this work is not so broad nor as theoretical as to require analytical skills of a licensed or professional engineer. The supervisor reviews the work by reviewing field notes, sketches made by the designer, or final construction maps drawn by the designer or drafting technicians who rely upon rough sketches and field notes they take or that are supplied by the designer. The Water Systems Construction Designer also develops contract forms, which are written descriptions of the work to be performed and include quantities and types of materials to be installed. Does related work as required.
TYPICAL WORK ACTIVITIES
Reads maps of proposed construction sites and visits these sites in order to design water facilities relative to above ground and underground facilities, which include sewers, utility poles, structures and landscape features.
Uses computer assisted design and drafting (CADD) to develop and plot the route the system is to take by taking into account the location of above and below ground facilities, which include sewers, street side, and state Department of Health standards.
Determines quantities of mains and appurtenances to be installed based upon the length and geometry of the system.
Estimates costs of materials to be installed in the system by reading cost data supplied by engineers or supply houses; reviews available materials and orders and schedules material for projects.
Estimates the contractor's cost of installing a system by multiplying the footage of the system by a given constant, which is calculated by the supervisor.
Answers any questions that Water Systems Construction Inspectors and Engineering Technicians may have regarding the interpretation of construction drawings.
Completes information on a contract form describing the nature of the work to be done, costs of the work, and materials to be installed.
Completes the appropriate forms to acquire the necessary permits relating to the construction projects as necessary.
Completes the required forms for the State Department of Health application for approval of the project and lists the nature of the work done, the location of the work, and the cost of the work, to comply with New York State Health standards.
Completes the form for Board of Director's approval and lists contractor's costs, OCWA labor costs, and material costs.
Prepares monthly and annual reports by listing mains, hydrants, and valves installed or retired.
Reviews field projects as required.
Responds to questions relative to water systems construction work.
