Title: CSA S250 Standard MAPPING OF UNDERGROUND UTILITY INFRASTRUCTURE


1
CSA S250 StandardMAPPING OF UNDERGROUND UTILITY
INFRASTRUCTURE
  • Bob Gaspirc, OLS, CLS, OAEM
  • Chair, CSA S250 Technical Committee
  • Manager, Mapping Services. City of Toronto
  • URISA - Ontario Chapter "Be Spatial'09" AGM
    Program and EXPO
  • May 5, 2009

2
Critical Infrastructure Dependencies
3
Space in the ROW is limited
4
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.
5
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,

6
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?

7
Question?
  • How will you demonstrate that your records are
    evidence that an event, activity, or task
    occurred or did not occur?

8
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

9
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

10
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

11
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

12
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,
    )

13
CSA s250 Mapping of underground infrastructure
  • Applying the standard to an organizations
    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

14
CSA s250 is Part of the decision framework
Acts, regulations, by-laws, codes Results of
court actions/decisions, other legal proceeding
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
Enables Framework for collection, access
exchange, and distribution
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.

16
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

17
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

18
Why a CSA based standard?
  • Part of the National Standards System accredited
    by the Standards Council of Canada
  • Provides management framework for administering
    technical committee
  • Acts a facilitator provides neutral third party
    forum, process, and structure for developing a
    consensus standard

19
TC CSA s250
Mandate The Committee shall be responsible for
developing and maintaining standards related to
mapping and recording of existing in-service
underground utility infrastructure and related
appurtenances below, at, or near grade and those
that are either abandoned or that are reserved
for future use.

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?

24
Map record accuracy
Spatial Accuracy Level Description Geodetic Reference
1 Accurate to within /- 10cm in the xyz projection coordinate system and referenced to an accepted geodetic datum within a 95 confidence level absolute
2 Accurate to within /- 30cm in the xyz projection coordinate system and referenced to an accepted geodetic datum within a 95 confidence level Absolute
3 Accurate to within /- 30cm in the xyz projection coordinate system and referenced to an acceptable topographic or cadastral feature within a 95 confidence level Relative
4 Accurate to within /- 100cm in the xyz projection coordinate system and referenced to an accepted geodetic datum within a 95 confidence level Relative
0 No information available related to spatial accuracy N/A
25
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

26
Expected Outcomes
  • 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)

27
What does it mean to megt
  • 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

28
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
