2Critical Infrastructure Dependencies
3Space 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.
5Infrastructure 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,
6Local 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?
7Question?
- How will you demonstrate that your records are
evidence that an event, activity, or task
occurred or did not occur?
8Utility 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
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 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
10Good 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
11CSA 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
12Benefits 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,
)
13CSA 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
14CSA 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
15Background
- 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.
16What 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
17Build 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
18Why 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
19TC 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.

23Examples 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?
24Map 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
25TC - 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
26Expected 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)
27What 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
28Next 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
