Work Plan <br />Cleaning Operation <br />Houston & Harris utilizes Vector Combination Cleaning trucks. In addition to one <br />Yactor unit assigned to this project on a daily basis, five additional Vector units are <br />available. $eing thoroughly familiar with the area, city procedures aad protocol required, <br />reduces bst production. Nght work has been factored into the propose] to account for <br />~ both high tra$xc and flow. <br />The following procedwes will be followed on a daily basis: <br />After reviewing the maps to determine the start location, the eperator will fill the Vector <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 lids. Traffic control will be provided when necessary. <br />Once the tocatian is deemed safe, the manhole lid is removed. The appropriate cleaning <br />nozzle for the task is chosen and attached to the Vector hose. The operator starts on the <br />downstream manhole and runs the nozzle to the u <br />as the hose is pulled back. When neces ~~ manhole to hydro-flush the line <br />sary, in addition to the h tiro-flushin a vawum <br />Process is applied to the line. Y g. <br />After the hydro-flushing process is complete, the operator replaces the manhole cover <br />back on the rnanhoie and safely moves to the next Location. Documeraation is validated <br />by the oPeTator utilizing a city supplied scantron 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 ~nSpeCtiOn OperatlOhS <br />Houston & Barris 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 procedums will be followed on a daily basis: <br />`~~ ~~'u!8 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.
