44、ty infrastructure0IntroductionThe purpose of this Standard is to specify the mapping records requirements used to identify and locate underground utility infrastructure. This Standard is intended to promote the use and drive the advancement of mapping records during the planning, design, constructio
45、n, and operation of underground utility infrastructure.Underlying the development of this Standard is the two-fold recognition that it is a privilege, not a right, to bury anything underground in the public right of way and that it is in consideration or exchange for that privilege, that the owner i
46、s obliged to provide an accurate and retrievable as-built location of that utility infrastructure.The underground is a maze of pipes and cables. Currently, thousands of kilometres of underground pipes and cables have never been accurately mapped or recorded. Infrastructure in Canadas older cities wa
47、s installed more than 100 years ago when as-built drawings, if any existed, referred to surface features that have long since disappeared. Up until recently, recording the presence and location of such utilities was not formally required or was not carried out in an accurate or methodical way. Today
48、, many of the records that do exist are in formats that are incompatible between utilities, making it difficult to position one companys pipes relative to anothers cables.With so many communications lines, fibre-optic cables, and petroleum, natural gas, electricity, water and sewer lines, public saf
49、ety issues arise as to how quickly utility infrastructure can be located and accurately identified in order to avoid an excavation mishap that could result in significant damage, an interruption of service, possible serious injury to workers or the public, or negative impact to the environment.Municipal authorities and the construction industry are now making a concerted effort to prevent accidental damage to underground utility infrastructure. For example, the Common Ground Alliance (CGA) has launched a “Call Before You Dig” program des
