accomplished by the use of several different software applications. This <br /> research is carried out by simultaneously using the following applications; <br /> "As-Construct Research'; "Cassworks 7'; "Cut Research'; "Deed Records', <br /> "EWEB As-builts'; "Gas Co. As-Builts', "Microfile Index'; "Myriad'; "RLID'; <br /> "Sewer Connections', and "TV Reports". Research is not limited to the use of <br /> these applications and the efficient use of them is dependant on the <br /> Engineering Technician's knowledge of and proficiency with them. Each has <br /> limitations as to the amount of information they provide. <br /> i With a copy of the reference map, the previously mentioned databases are <br /> opened on the desktop PC. A printout of the information provided by each of <br /> the applications is cross referenced to determine the most accurate <br /> information. At this point, if the information is available in the format of an <br /> AutoCad drawing, fhe Engineering Technician exports the information to the <br /> reference drawing in the AutoCad drawing they have created. Many times it is <br /> necessary to take the information and create fhe line work by hand in <br /> AutoCad. <br /> Conflicts in information arise when the horizontal and vertical locations of <br /> structures do not agree with each other in the database or with the field <br /> survey data or both. Resolution is made by knowledge of fhe nature and <br /> <br /> j construction of the structures, gathering more recent information from Public <br /> Works Maintenance and often by another field visit to determine more <br /> information. <br /> As an example, in the development of Wastewater Rehabilitation plans, the <br /> resulting collection of information is evaluated and compiled into folders <br /> sorted by area or proposed plan sheet. This information is forwarded to the <br /> project manager who determines the priority for potenfial rehabilitation of <br /> wastewater lines. The information is then returned to the Engineering <br /> Technician who uses the information to create project plans. <br /> Understanding the nature and construction of sewer mains, utilities, and <br /> roads and even an understanding of the archival techniques and limitations <br /> can help in performing the research. A knowledge of the capabilities and <br /> limitations of the many different Technological advances in the sewer <br /> rehabilitation industry is necessary so as to properly evaluate the potential for <br /> repairs to defective systems. <br /> e) Existing infrastructure conditions <br /> • Opening and sometimes entering live wastewater and storm sewer <br /> manholes to measure depths, verify directional flow and determine the <br /> nature and severity of defects <br /> • Viewing of video taped inspections of wastewater and storm mains <br /> • Reviewing logs of video taped inspections <br /> • Reviewing Defect Summaries of sewers <br /> Experience with the nature of defects of a particular component of the <br /> infrastructure is necessary. <br /> An example of this would be an understanding of the materials, products <br /> and techniques involved in the construction of a wastewater main <br /> constructed during a particular era. In the 1950's particular products were <br /> Engineering Technician Position Review 5 January 2004 <br /> <br />
