Space in the ROW is limited
Traffic Congestion is increasing If unchecked By 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.
Infrastructure Challenges Definitions, terms, features, symbology Cost management issues, business disruptions to revenue stream, disruption to other utilities, damage prevention, coordination, circulation Reduced right of way size, congestion, no cut moratoriums, advancements of trench technology,
Local Government Responsibilities Owner/user of the public roads under its jurisdiction Public roads are held in trust for the long- term benefit of the public, the taxpayers & other users of the public roads Policies are needed that will withstand the test of time, to administer the surface & subsurface space To support municipal activities, there is a need to know what is in the right of way & where is it located?
Question? How will you demonstrate that your records are evidence that an event, activity, or task occurred or did not occur?
Utility Records - Evidence of an event, activity, task As-built drawings, plans, sketches Circulation drawings, mark ups Design drawing Permit drawings, sketches Approved design drawing used for purposes of construction Field notes, locator notes, inspector notes, Digital representations of above
Key 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 completed Have record containing relevant, factual, and timely data Be able to access and retrieve utility record Be able to share, manipulate, analyze, distribute data Make and act on decisions using reliable and dependable utility map records
Good records - better decision making CSA s250 provides: Terminology –characteristics of a record Authenticity – what it purports to be Reliability – trusted as full and accurate representation of the fact Integrity – complete and unaltered Usability – can be located, retrieved, presented, and interpreted Codification 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 infrastructure Quality levels envisioned to be as per ASCE 38- 02, Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data
CSA s250 Mapping Standard also Provides a technically neutral language Creates 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 challenges
Benefits to all Improved safety of company and contractor employees and the general public by decreasing utility hits/strikes Improved reliability and accuracy in the location of underground utility infrastructure mapping records and supporting data Lower 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, …)
CSA 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
CSA s250 is Part of the decision framework Acts, regulations, by-laws, codes Results of court actions/decisions, other legal proceeding Enables Framework for collection, access exchange, and distribution Business policies, best practice, procedures, and operational requirements STANDARDS ISO 15489 - records management CAN/CGSB-72.34, Electronic records as documentary evidence standards endorsed for the Canadian Geospatial Data Infrastructure (CGDI) (DRM, metadata, web services etc) CSA s250 – Mapping of Underground Utility Infrastructure Technology neutral language Improves, enhances records management during design, construction, operation, retirement phase of plant
February 9, 2007Regional Public Works Commissioners of Ontario 15 Background RPWCO 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; and planned construction activity in the road allowance.
What was found No current mapping standard that addresses accuracy, process, and identification of underground plant Historically, high variability in the reliability, consistency & accuracy of mapping underground utilities The (Ontario and BC) Common Ground Alliance movement have introduced Mapping “Best Practices” for Damage Prevention Recent technological advancements allows for: Improved records capture (GPS, LIDAR, imagery) Better records storage (GIS, CADD systems) Enhanced access and sharing mechanisms Growing appetite to share utility mapping records Utility owners/operators already have internal standards
Build Up to Development of Standard 2005 to 2006 Q3 – ORCGA Mapping Best Practices finalized and committee dissolved 2006 Q1 to Q3 – RPWCO gathered support to develop a mapping standard 2006 Q3 – RPWCO approached CSA to conduct a study on the viability of developing a new mapping standard 2006 Q4 to 2007 Q2 – Feasibility Task Force 2007 Q2 – Call for participation nationwide to become member of committee to develop new CSA standard 2007 Q3 – New CSA S250 Technical Committee established and kick off
Why a CSA based standard? Provides management framework for administering technical committee Acts a facilitator; provides neutral third party forum, process, and structure for developing a consensus standard Part of the National Standards System; accredited by the Standards Council of Canada

Committee Meetings Held Thus Far October 2007 (Toronto) - Kick-off and member training session December 2007 (Mississauga) – Lifecycle of plant February 2008 (Mississauga) – Content development April 2008 (Mississauga) – Content development June 2008 (Vancouver) – Content development September 2008 (Mississauga) – Rough outline review November 2008 (Mississauga) – 1 st reading of draft January 2009 (Calgary) – 2 nd reading of draft Teleconferences as required
Examples of recent committee discussions … Feature description and symbology Common symbology and attributes to be used to graphically represent utility infrastructure and its associated attributes Municipal utility coordination How will data get shared? What data needs to be shared? How do changes get communicated?
Map record accuracy Spatial Accuracy LevelDescriptionGeodetic Reference 1Accurate to within +/- 10cm in the xyz projection coordinate system and referenced to an accepted geodetic datum within a 95% confidence level absolute 2Accurate to within +/- 30cm in the xyz projection coordinate system and referenced to an accepted geodetic datum within a 95% confidence level Absolute 3Accurate to within +/- 30cm in the xyz projection coordinate system and referenced to an acceptable topographic or cadastral feature within a 95% confidence level Relative 4Accurate to within +/- 100cm in the xyz projection coordinate system and referenced to an accepted geodetic datum within a 95% confidence level Relative 0No information available related to spatial accuracyN/A
TC - Challenges & Observations Need to remind ourselves of the benefits of having a standard Need to maintain interest in the standard by committee members and all stakeholders Need to assess how the standard will be embraced and then sustained Definitions: relative, absolute, content, accuracy, depth of cover, elevation
Improved reliability and accuracy in the location of underground utility infrastructure mapping records & supporting data Improved safety of company & contractor employees and the general public by decreasing utility hits/strikes Lower cost in the utility design life cycle by sharing accurate & complete utility records in a timely fashion amongst all users (municipalities, carriers, contractors, designers, consultants, locators…) Expected Outcomes
What does it mean to me> Once CSA S250 is published, stakeholders may: Ignore it Use standard to support their records management frameworks Voluntarily modify internal practices, processes, systems to meet or exceed standard formally mandate implementation of all or part of CSA standard in regulatory/legislated framework
Next Steps - Timeline for Publication Complete rough outline June 2009 Enquiry (public review) stage – Fall 2009 Approval by CSA Technical Committee – Winter 2009 / 2010 Ready for publication – Summer 2010 CSA “S250” – Mapping of underground utility infrastructure
