Site Supervisor

Description

Job Description:

• Organize the materials needed for each section of trench.
  • The pipe or manhole would generally be placed beside the trench by the loader, and the topman would be walking several feet back and forth from a supply crate or supply boxes to the trench to carry smaller accessory parts, small tools, supplies such as 2×4 wood pieces, etc to the trench area.
  • The topman might carry some of the light pipe from the supply pile to the trench.
  • The topman could be dropping small supplies into the trench for the labourers to use.
• Cut or sharpen pipe
  • The topman might have to cut pipe, with a quick-cut saw, into a shorter length in order to be the correct length to attach to a manhole or other structure.
  • The end of a pipe might have to be sharpened in order to have a bevelled end, by using the saw to bevel it, so the pipe can fit into another pipe or structure.
• Rigging pipe with nylon slings or pipe cables
  • The topman places a sling (<5 lbs) or a single pipe cable (<10 lbs) around a pipe that is lying beside the trench. The device used depends on the weight of the pipe.
  • If it is a light pipe, the topman can lift an end of the pipe to get the sling or cable around the pipe.
  • If the pipe is heavier, the topman can place the cable on the ground and role the pipe over the cable and into position. The cable would then be fastened together.
  • When the labourers in the trench need another pipe, the excavator operator swings the excavator bucket into position over the pipe that is beside the trench and the topman lifts the top of the sling or the top ring of the pipe cable and hooks it onto a hook on the excavator bucket and then the excavator lifts the pipe and places it into the trench.
  • After the pipe is disconnected from the pipe cable in the trench, the excavator would bring the pipe cable out of the trench and place it beside the next pipe at ground level.
• Rigging concrete manholes or other concrete structures with a manhole lifting cable or manhole lifting chains
  • Manhole lifting cables or lifting chains have a metal ring on top with 2 cables or 2 chains that are several feet long that extend down from the ring and the cables or chains have an attachment on the bottom of them that can be attached to the concrete structure.
  • A manhole lifting cable weighs around 25 lbs and a manhole lifting chain assembly weighs about 50 lbs. The type of lifting device used depends on how heavy the concrete structure is.
  • The lifting cable or chain would be near the concrete structure and the topman attaches the end pieces of the cables or chains onto the concrete structure by clipping it on.
  • In a separate movement, the topman will lift the ring portion of the lifting cable or lifting chain and hook it onto the excavator bucket hook so the excavator can lift the concrete structure and lower it into the trench. The topman isn`t lifting the full weight of the lifting cable or lifting chain, only the weight of the ring and some of the cable or chain
  • The lifting cables or chains would be placed near the concrete structures by the excavator machine, but the topman might have to drag the chains or cable closer to the structure.
• Other miscellaneous labour duties such as drilling, cutting or grinding bolts, using a shovel, using other small tools.
• If the crews are in the road-building phase of the job, the topman would be assigned other duties such as running a packer machine or general labour duties involving a shovel, or rake or fixing deficiencies that have been found on the job site.
