Learner Outcomes: 

Upon successful completion of the course, students will be able to: define the following terms: bench mark, horizontal, level, offset, percent of grade, plumb, rate per foot, station, and vertical; describe the use of common construction referencing methods to locate object as manholes or utilities; given reference points for an object, locate the object within .25’; describe how stationing systems are used to locate measurements within the project; given a series of hub grades, use squaring principles to set offset stakes at 25’ intervals to establish a trench line; given a grade sheet with a set of elevations, calculate elevations and elevation changes using a rate per foot or percentage of slope; given a partially completed cut sheet, calculate the cut or fill for each station; given an established trench line, set up and demonstrate the use of a pipe laser to check for proper grade within the excavation; demonstrate the set up of the pipe laser in a manhole to check for line and grade; demonstrate the correct set up of a transit level; given a set of elevation hubs and working on a team, calculate each elevation to within +/- .02’; define the following terms: benching, shield, competent person, slope ratio, cross braces, sloping, excavation, trench, hazardous atmosphere, uprights, sheeting, and wales; describe three warning signs of a possible trench cave-in; describe two types of protective systems for excavations; describe the soil characteristics of type A, B, and C soil, and state the sloping requirements for each soil type; list the OSHA requirements for access to and egress from excavations; given a set of construction scenarios, determine the access/egress requirements for each scenario; given the proper tools and equipment, and working in teams, demonstrate the installation of timber tight shoring, shoring with screw jack bracing, and hydraulic shoring; define the following terms: building sewer, gravity flow, main, sanitary sewer, sanitary sewer system, sewage, sewers or sewer systems, lateral, and manhole; identify and describe the purpose of the tools and equipment used in sanitary sewer installation; working as part of a team, demonstrate the installation of 110 feet of PVC pipe, and demonstrate installation of PVC laterals; list and describe the tools and equipment used in storm sewer installation; working as part of a team, demonstrate the installation of storm sewer pipe; identify and describe the purpose of the tools and equipment used for repair and tie-in of PVC and concrete pipe; working as part of a team, demonstrate the repair of PVC and concrete pipe; describe and demonstrate the set-up and operation of low-pressure air testing equipment on sewer lines; identify and describe the purpose of the tools and equipment used form manhole invert construction; working as part of a team, demonstrate the construction and shaping of an invert within a manhole; describe five types of pipe used for storm drain and sub drain systems; identify and explain the purpose of each of the following tools and pipe appurtenances: all-thread rod, tee bolt, dresser coupling, wrap-around repair clamp; describe and demonstrate joining pipe sections using mechanical and Tyton (push-on) joint connections; describe and demonstrate Ductile Iron water pipe installation and assembly techniques; given a drawing of a fire hydrant assembly, assemble the hydrant within tolerance and according to the drawing; describe and demonstrate hydrostatic testing procedures for Ductile Iron pipe and demonstrate test pump set-up and operation; given a formula and problems related to leakage during hydrostatic testing, calculate the maximum allowable leakage for each problem; describe and identify the following tools and appurtenances: corporation stop, curb stop, tapping saddle, tapping machine, flaring tool; identify the components of a Mueller model B-100 tapping machine, inspect each component, and set up the machine; describe and demonstrate the procedures for direct tapping and assembling of a water service connection; describe and demonstrate the maintenance procedures for the Mueller model B-100 tapping machine; describe the protocol for using a central “One Call” number; given a list of “One Call” numbers and a state or county, locate the correct number; given the need to excavate near a utility, describe notification requirements and location services provided by the local utility company; and describe and demonstrate the purpose and process of probing and potholing a utility.


Major topics provide the basic knowledge and skills that CCLs need to work safely in trenches, and correctly install, tap, and repair PVC, Ductile Iron and concrete pipe.
