Work Plan <br />Cleaning Operation <br />Houston do Harris utilizes Vactor combination Gleaning trucks. In addition to one <br />Vactor unit assigned to this project on a daily basis, five additional Vactor units are <br />available. Being thoroughly familiar with the area, city procedures and protocol required, <br />reduces lost production Might work has been factored into the proposal to account for <br />both high traffic and flow. <br />The following procedures will be followed on a daily basis: <br />After reviewing the maps to determine the start location, the operator will fill the Vactor <br />tank with water from a hydrant utilizing the city supplied water meter, for hydro -flushing <br />Purposes. This procedure will occur throughout the day. The operator then assesses <br />manhole locations ensuring the safest position of the vehicle prior to setting up to begin <br />the washing process. Included in this set-up procedure are assurances of traffic cones <br />around work area and equipment as well as the use. of gas detector meter readings <br />indicating safe removal of manhole Gds. Traffic control will be provided when necessary. <br />Once the location is deemed safe, the manhole lid is removed. The appropriate cleaning <br />nozzle for the task is chosen and attached to the Vactor hose. The operator starts on the <br />downstream manhole and runs the nozzle to the upstream manhole to hydro -Hush the line <br />as the hose is pulled back When necessary, in addition to the hydro -flushing, a vacuum <br />process is applied to the line. <br />After ,the hydro-fiusbing procesa is complete, the operator replaces the manhole cover <br />back on the manhole and safely moves to the next location. Documentation is validated <br />by the operator utilizing a city supplied wantron sheet that includes details such as, <br />material in the line, type of nozzle used, and how many passes were needed on a <br />particular line segment. <br />This process is repeated for each line segment. <br />Video inspection Operations <br />Houston & Harris utilizes RST video inspection equipment. In addition to one Video <br />inspection unit assigned to this project on a daily basis, three additional Video Inspection <br />units are available. <br />The following Procedures will be followed on a daily basis: <br />After reviewing the maps to determine the start location, the operator assesses manhole <br />locations to ensure the safest positioning of the vehicle, and sets -up to begin the video <br />process. Traffic eor>trol will be provided when necessary. Included in set-up procedures <br />are assurances of traffic Cones around work area and equipment and use of gas detector <br />
