4Traffic Congestion is increasing If uncheckedBy 2031 we will need 19 additional lanes of expressway capacity to move suburban commuters to jobs in the City and City residents to jobs in the 905 region which cannot be effectively served by public transit.Road system reaching capacity The road system can't continue to accommodate car-dependent sprawl. Projections show that our arterial roads will be seriously congested, both in the regions and in Toronto.Air pollution Increased traffic congestion will further pollute what is already the poorest air quality in Ontario and may limit the ability of the entire GTA region to attract people and businesses.Ability to attract people and businesses The cost of installing and maintaining infrastructure and services at lower densities over a broader area will be in the billions of dollars, while in the City, parts of the existing infrastructure are under-utilized.Cost of installing/ maintaining infrastructure and servicesLost farmland - 3,000 hectares per year Between 1976 and 1996, over 60,000 hectares of farmland was paved over, and we continue to lose over 3,000 hectares of farmland per year.
5Infrastructure Challenges Definitions, terms, features, symbologyCost management issues, business disruptions to revenue stream, disruption to other utilities, damage prevention, coordination, circulationReduced right of way size, congestion, no cut moratoriums, advancements of trench technology,
6Local Government Responsibilities Owner/user of the public roads under its jurisdictionPublic roads are held in trust for the long-term benefit of the public, the taxpayers & other users of the public roadsPolicies are needed that will withstand the test of time, to administer the surface & subsurface spaceTo support municipal activities, there is a need to know what is in the right of way & where is it located?As you are aware, the City has a dual role to play on the TPUCC. It is both a user and owner of the public highways under its jurisdiction.The common and statute law recognizes that public highways have special characteristics which distinguish them from private property.Public highways are held in trust for the long-term benefit of the public, the taxpayers and other users of the public highway.This trust necessitates that municipalities develop policies to administer the surface and subsurface space in the public highways that will withstand the test of time.
7Question?How will you demonstrate that your records are evidence that an event, activity, or task occurred or did not occur?Accidental contact with underground utility lines can be dangerous and cost millions in repairs and delays. Time spent properly locating and mapping utilities before starting construction can significantly lower the risk
8Utility Records - Evidence of an event, activity, task As-built drawings, plans, sketchesCirculation drawings, mark upsDesign drawingPermit drawings, sketchesApproved design drawing used for purposes of constructionField notes, locator notes, inspector notes,Digital representations of aboveThese key phrases are not defined by the law, but the Canada Evidence Act, as well as most provincial and territorial evidence acts, contains the following provision, encouraging the use of standards:31.5 For the purpose of determining under any rule of law whether an electronic document is admissible, evidence may be presented in respect of any standard, procedure, usage or practice concerning the manner in which electronic documents are to be recorded or stored, having regard to the type of business, enterprise or endeavour that used, recorded or stored the electronic document and the nature and purpose of the electronic document..
9Key Goals –improve decision making during utility life cycle You must:Be ready to produce utility “record” as evidence that an event, set of activities, or task occurred and was completedHave record containing relevant, factual, and timely dataBe able to access and retrieve utility recordBe able to share, manipulate, analyze, distribute dataMake and act on decisions using reliable and dependable utility map recordsThe basic process by which a standard is developed is consistent among all standard development organizations, national and international. The following is a simplified breakdown of the process:Identification of the need for new standardPreliminary study and preparation of a draft outlineEstablishment of a committee (pre-existing or new)Committee meetings and consensus building on the draftVote on the draft standardPublication of the standardStandards help organizations ensure their products and services are consistent, compatible, effective, and safe. They also help the public understand these important safety requirements.Most standards are voluntary - there are no laws requiring their application - but an increasingly competitive market place for goods and services means that more and more customers are demanding adherence to specific standards. Governments also make some standards mandatory by referencing them legislatively or through regulations.
10Good records - better decision making CSA s250 provides: Terminology –characteristics of a recordAuthenticity – what it purports to beReliability – trusted as full and accurate representation of the factIntegrity – complete and unalteredUsability – can be located, retrieved, presented, and interpretedCodification of best practises to qualify the level of reliability of mapping records information that is collected and used to depict the location and attributes of utility infrastructureQuality levels envisioned to be as per ASCE 38-02, Standard Guideline for the Collection and Depiction of Existing Subsurface Utility DataAccuracy of mapping recordsAccurate content, completeness, extent of coverage, completeness, and spatial accuracy(Absolute & Relative) Accuracy levels being defined
11CSA s250 Mapping Standard also Provides a technically neutral languageCreates a consistent and repeatable approach to mapping and recording of facility information“as per CSA S250”Promotes communication among utility infrastructure stakeholders and reduces infrastructure life-cycle challengesOwners, operators and regulators nationwide want to better manage record the existence, identification, and depiction, and location of buried plant during the planning, design, construction and operation, retirement phases.The development of a standard for mapping of underground utility infrastructure is a logical next step, building on best practicesRefer back to Common Ground Alliance in Ontario and BCInfrastructure challenges:Defintions, terms, symbology, features, have known meaning and can be applied to :Cost management issues, business disruptions to revenue stream, disruption to other utilities, damage prevention, , Time cost, coordination, reduced right of way size, congestion, no cut moratoriums, advancements of trench technology,-By improving communication between infrastructure stakeholders there is a better opportunity to cooperate and collaborate rather than work in isolation – co-builds, joint trenching,
12Benefits to allImproved safety of company and contractor employees and the general public by decreasing utility hits/strikesImproved reliability and accuracy in the location of underground utility infrastructure mapping records and supporting dataLower cost in utility design life cycle by sharing accurate and complete utility records in a more timely fashion amongst all users (owners, municipalities, designers, contractors, locators, …)
13CSA s250: – Mapping of underground infrastructure Applying the standard to an organization’s business will not eliminate the possibility of litigation, but it will make the production of electronic records easier and their acceptance in a legal proceeding more certain.This standard is not intended to replace, reduce, or eliminate the “Call before you dig” requirements for field locates of buried utilities
14CSA s250 is Part of the decision framework Acts, regulations, by-laws, codesResults of court actions/decisions, other legal proceedingBusiness policies, best practice, procedures, and operational requirementsThis standard can be applied to the policies, procedures, practices and documentation that organizations need to establish the integrity and authenticity of recorded information on field notes, plans, sketches, as-builts, GIS systems, or other data/information management systemsIts technology-neutral language allows organizations to apply the procedures to various types and combinations of Information Technology“…as per CSA s250 statements - will assist them in demonstrating compliance with legal requirements, without dictating the types of technology required.As a codification of best practices become more embedded into the evolution of this standard, organizations can and will be able to rely on this standard if they implement the appropriate procedures and follow them.Applying the standard to an organization’s business will not eliminate the possibility of litigation, but it will make the production of electronic records easier and their acceptance in a legal proceeding more certain.STANDARDSISO records managementCAN/CGSB-72.34, Electronic records as documentary evidencestandards endorsed for the Canadian Geospatial Data Infrastructure (CGDI) (DRM, metadata, web services etc)CSA s250 – Mapping of Underground Utility InfrastructureTechnology neutral language Improves, enhances records management during design, construction, operation, retirement phase of plantEnablesFramework for collection, access exchange, and distribution
15Regional Public Works Commissioners of Ontario BackgroundRPWCO Task Force formed in June 2005 in order to improve the efficiency and safety of road and utility construction by developing standards for the following:as-built records of buried utilities;electronic formats of as-built records; andplanned construction activity in the road allowance.February 9, 2007Regional Public Works Commissioners of Ontario
16What was foundNo current mapping standard that addresses accuracy, process, and identification of underground plantHistorically, high variability in the reliability, consistency & accuracy of mapping underground utilitiesThe (Ontario and BC) Common Ground Alliance movement have introduced Mapping “Best Practices” for Damage PreventionRecent technological advancements allows for:Improved records capture (GPS, LIDAR, imagery)Better records storage (GIS, CADD systems)Enhanced access and sharing mechanismsGrowing appetite to share utility mapping recordsUtility owners/operators already have internal standards
