The recently passed Senate Bill 18-167 has many new provisions that could impact the GIS community and location of in-ground infrastructure. Find out about how this bill might impact your organization.

1. Will this law impact your
GIS?

11. What?
Current Excavation Damage
Prevention Law
 Before conducting an excavation
Contact Colorado 811 (Utility
Notification Center of Colorado)
 They contact the owners of the
underground facilities based on tier
type
 Violations enforced through civil
actions by damaged parties
11

12. Why?
Enforcement is Inadequate
 According to the United States
Department of Transportation's
Pipeline and Hazardous Materials
(PHMSA) 2016 report
 Which may eventually result in the
WITHOLDING OF FEDERAL FUNDS FROM
COLORADO
12

14. This is your
presentation title

15. Senate Bill 18-167
Underground Damage Prevention
Safety Commission
 Rule-making and enforcement authority
 Colorado 811 is required to provide
administrative support – Central
resource
 A review committee determines if a
violation has been committed
 Commission determines action on
violation
15

16. Senate bill 18-167
Follow the Money
 Fines credited to damage prevention
fund
 Educational programming
 Grants to improve the worker and
public safety
16

17. Which Tier?
Currently
 Tier 2 members - Local governments,
special districts, cable and small
telecom providers
- Contacted directly by excavator
 Tier 1 members – all the rest
- Colorado 811 contacted directly
17

18. Who?
Now it gets interesting
 Current law – Only the excavator can
submit a location request to 811
 SB 18-167 allows a licensed
professional engineer to submit a
location request
 Engineer is required to ensure plans
meet ASCE accuracy of underground
facility standards.
18

19. Tier No More
Effective January 1, 2021
 All underground facility owners and
operators are full members
 Colorado 811 will be contacted
 ALL NEW UNDERGROUND FACILITIES
INSTALLED AFTER JANUARY 1, 2020 MUST
BE ELECTRONICALLY LOCATABLE WHEN
INSTALLED.
 Home rule local governments must
adopt safety program or create their
own.

20. GIS Community Impact?
Our Data is a starting point
 Currently used as a starting point
 Future – Source with on-the-ground
updates
 Closely linked to GPS
 Used in ways we have not imagined
20

21. Caution

22. 22
 You do not want to accept liability
base on GIS coordinates that have
not been verified
 Where does your GIS come from?
 How do you verify locations?
 How is the GIS data used?
 Do you have solid disclaimers?
 Do you have metadata?

23. The line is a bit foggy

24. 24
This guideline is a protocol for engineers to use in
rendering a professional opinion about the quality and
reliability of utility information depicted on excavation
plans.
By following the process spelled out in ASCE 38-02, an
engineer can quantify the quality of the utility information
in terms that a lay person or non-engineer can
understand.
ASCE 38-02 defines four distinct levels of quality with
respect to utility information. The quality of the utility
information is ranked from the most reliable, Quality
Level A, to the least reliable, Quality Level D.

 Quality Level D
Information derived from existing records
or oral recollections.
-> GIS and those that are in the know

27. 27
 Quality Level C
Information obtained by surveying and plotting
visible above-ground utility features and by using
professional judgment in correlating this
information to quality level D information.
-> GIS and survey grade GPS

28. 28
 Quality Level B
Information obtained through the
application of appropriate surface
geophysical methods to determine the
existence and approximate horizontal
position of subsurface utilities.
Quality level B data should be
reproducible by surface geophysics at
any point of their depiction. This
information is surveyed to applicable
tolerances defined by the project and
reduced onto plan documents.

 Quality Level B

30. 30
 Quality Level A
Precise horizontal and vertical location of utilities
obtained by the actual exposure (or verification of
previously exposed and surveyed utilities) and
subsequent measurement of subsurface utilities, usually
at a specific point. Minimally intrusive excavation
equipment is typically used to minimize the potential for
utility damage.
A precise horizontal and vertical location, as well as
other utility attributes, is shown on plan documents.
Accuracy is typically set to 15-mm vertical and to
applicable horizontal survey and mapping accuracy as
defined or expected by the project owner.
