What is MUCC GUIDE?

Michigan Utility Coordination Committee

Geospatial Utility Infrastructure Data Exchange

Creates a mature and sustainable approach to data collection, management and dissemination

of 3D geospatial data on underground utility infrastructure by capturing accurate XYZinformation at the time of installation and

organizing it in a spatial database format for secure, highly accessible use by downstream

stakeholders.


Goals

Create a central repository where all survey data can be submitted, stored, managed and shared.

Provide user access to the central repository in order to allow stakeholders access to the geospatial utility information

Focus the acquisition of accurate geospatial utility information solely on underground utilities


Goals

Identify challenges associated with acquiring

accurate spatial data during installation

Identify short and long-term benefits of

acquiring accurate spatial data

Identify the technical considerations for

acquiring accurate spatial data


Anticipated Benefits

Increased efficiency in project coordination during

design

Better project decision making

Improved project communication

Utilization of asset data through it’s life cycle

Reduce construction delays and user delays

Improve public safety and reduce owner & utility

company risk

Reduce costly utility conflicts during construction


Anticipated Benefits


Considerations

What location data

is important to capture?

X and Y

X, Y and Z


Considerations

Who Collects the Geospatial Data?

• Utility Company

• Utility Contractor

• MDOT

• Professional Surveyor

• Combination of above


What will the standards include?

• Level of accuracy

• Attribution

• Data format


Value of Additional Info

• Site conditions

• Installation methods

• Personnel involved

• How much is too much?

• Etc.


Workflow Overview


Spatial Data Collection


Accurate Data Collection

Relative to the National Spatial Reference

System

• Northing & Easting (MISPC, International Feet)

• Elevation (NAVD’88 Datum, International Feet)

Top of the pipe / conduit

Survey grade accuracy

• H - 5cm (0.16 feet) x V - 10cm (0.33 feet)


Required Observations

Transmission / distribution main lines Starting / ending points

100’ Interval

Any deviation in alignment (3D)

Any changes in facility characteristics

Start / end points for vaults

Multi-duct installations, observations shall be taken from

the top center of the duct bank. Recording duct bank

size



Appurtenances installed concurrently with new mains

• Tap-in location at main and ROW line points

New appurtenances from existing mains

• Tap-in at main and ROW line points for:

• Gas - 2 inches and greater

• Telephone - Fiber or copper cables 25 pair and greater

• Electric - Secondary and higher voltage lines

*Appurtenances, with respect to this pilot, are defined as service leads and stubs.



Directional drilling

• Actual observations at start and end

• Intermediate points to provide elevation curve data

• Intermediate points not directly accessible -Derive from actual ground elevation minus boring head depth readout

Facilities installed in existing conduit

• Installation method identified as “insertion”

• Necessity dependent on the existing conduit’s location relative to the existing roadway infrastructure


File Specifications

• .xls

• .xlsx

• .shp

• .gdb

• .txt

• .csv

Acceptable formats:


Pilot Projects (7)

• Data collection

• Provide MDOT with

data collected

• Additional costs

• Personnel impacts

• Equipment

procurement

• Required time

to process data

• Feedback on

requirements

• Best practices

• Positive impacts

to utilities

Guide Key Findings

Further development of the GUIDE Requirements Document

Potential for significant roadway agency impacts

Training requirements

Survey staff proximity to projects

Coordination of surveying efforts

Development of contract specific language

Lack of supporting utility conflict cost data


Data Acquisitions Lessons Learned

Data delivery standards

Coordination of data collection proved

challenging

Utility company contract provisions for

Costs


Overall Cost Benefit

Comparing Guide Costs to SUE

University of Purdue: SUE study 1999

71 projects studied

4 states

$4.62 saved for every dollar spent

Average 0.5% of construction cost

University of Toronto: SUE study 2006

9 projects studied

$2.05 - $6.59 for every dollar spent

Average 1.6% of construction cost

GUIDE resulted in cost of .75%-2% of construction cost


Pilot

• Set-up a draft database

• Enterprise database assembly

• Document pilot outcomes


Long term goals, pending pilot results

• Apply to all permitted

underground utilities

• Apply to MDOT

projects where new

municipal utilities are

installed and where

utilities (all) are

exposed
