Utility Coordination Process
• QLD: Existing records• QLC: Survey of aboveground utilities• QLB: Geophysical methods• QLA: Exposure (test holes/vacuum excavation)
2-7
Reality Check …
• Frequently cited reasons for project delays (DOT perspective):– Short timeframe for developing projects– Project design changes– Environmental process delays– Inefficiencies in utility coordination
• Inaccurate location and marking of existing utility facilities
• Identifying utility conflicts late in the design phase• Disagreements on recommended utility-related
solutions• Utility relocation costs not handled properly• …
2-8
Reality Check …
• Frequently cited reasons for project delays (utility owner perspective):– Limited resources (financial and personnel)– Utility owner’s project development process
protocols– Coordination with other stakeholders during
design– Coordination with other stakeholders during
construction– Changes in DOT design and schedules– Unrealistic schedule by DOT for utility
relocations– Internal demands (maintenance, service
upgrades)
2-9
Consequences of Bad Utility Information
• Incomplete/inaccurate utility data = BAD data
• Negative impacts:– Disruptions during construction– Unplanned environmental corrective actions– Damage to utility installations– Delays and project overruns
2-10
Utility Conflict Scenarios
• Utility facility vs. transportation design feature (existing or proposed)
• Utility facility vs. transportation construction activity or phasing
• Planned utility facility vs. existing utility facility
• Noncompliance with: – Utility accommodation statutes, regulations,
and policies– Safety or accessibility regulations
2-11
2-12
2-13
Solution Strategies
• Remove, abandon, or relocate utilities in conflict– Relocating utilities NOT NECESSARILY OR
ALWAYS the best or most cost-effective solution• Modify transportation facility• Protect-in-place utility installation• Accept an exception to policy
2-14
Transportation Design Changes
• Geometric alignment (horizontal/vertical):– Change grade– Offset centerline, widen one side of highway– Move ramps, driveways
• Structure dimensions, other characteristics:– Change embankment slope– Add/modify retaining wall to reduce slope
encroachment– Redesign bridge footings and abutments, move
pilings– Redesign drainage structures
2-15
Example: Widening Both Sides vs. One side of Highway
• Issues to consider:– Widening both sides of highway impacts
everyone (no one is spared!)– Widening one side can reduce utility impacts– Depends on what kind of utilities are affected
2-16
Example: Embankment
• Due to interstate widening, embankment had to be raised 50-60 feet
• Major gas and water facilities in the area• Large soil settlement expected• Modified project to protect-in-place
utilities:– Foam layer – Thin concrete cap
• Costly utility relocation was avoided
2-17
Example: Bridge
• Bridge project affected multiple utilities (power, water, sewer, etc.)
• Modifying horizontal bridge alignment slightly– Would have avoided any utility impact– Would not have impacted right-of-way– Would not have compromised bridge
construction• Discovered during construction… too late!• Utility relocation costs = $5,000,000
2-18
Example: Power Pole
• Rapid City, South Dakota• Conflict discovered at 30% detailed design• Redesign avoided utility adjustment• Additional costs were paid by utility

Example: Drainage Channel
• Rapid City, South Dakota• Impact discovered during preliminary
project scoping inspection• Typical concrete lined drainage ditch would
have impacted electrical cabinet and cables
• Recommendation: redesign sloped ditch to vertical wall
• Additional benefit: elimination of some right of way acquisition

Example: Traffic Signal Footing
• Deadwood, South Dakota• Pole to be placed in close proximity to
existing utilities• Pole location surveyed on ground by DOT• Utilities in vicinity identified by One Call• High cost to relocate existing utilities• QLA utility investigation• Recommendation: Reduce pole footing
diameter from 36” to 30”

Summary of Cost Savings
• Cost to relocate power facilities
$95,000• Cost to collect QLA data
- $5,785
• Cost savings to taxpayers
$89,215
2-38
Key Concepts
• Utility conflict management:– Does not start at 60% design– Does not end at letting
• Not all projects or locations need QLB/QLA data
• Goal: Avoid or minimize utility impacts• Strategies:
– Avoid unnecessary utility relocations– Evaluate design alternatives– Conduct utility conflict analysis

2 This matrix was created by _______3___________ to assist the UAO's in identifying conflicts between the UAO's facilities and proposed roadway construction. __________________ accepts no liability for conflicts overlooked for this report. Each UAO or designee is responsible to perform a detailed and comprehensive plans review for conflict analysis.

Disclaimer that the reviewer and their firm is not responsible for any missed conflicts. The blanks are for the name of the design firm. Phase that the plans represent.
Consider using the form from the beginning of a project as a tool for monitoring areas of concern with UAO facilities. That is the reason for the Phase Number space. The form is set up to: 1. Print legal size and have the header information on each page. 2. The cells where the conflicts are listed are set to word wrap automatically. 3. The footer is set to number the pages 1 of ??.
What is it the facility perceived to be in conflict with? It a possible conflict or actually in conflict with proposed work. Consider the trench and hole size required to place pipe and drainage structures. Don't forget aerial facilities when there are signals and large signs in the project.SUE work can be used to if a conflict is considered a possibility. This entry area is a tool to determine areas where test holes should be taken for confirmation or exclusion of a conflict.Entry area for the test hole number. Test holes should be numbered consecutively to avoid confusion. What can be done to remove the conflict? Don't forget to consult with the Designer for alternatives to the proposed construction.
Owner of the underground line.The standard reference used on FDOT plans is the Centerline of Construction, it is used for all components of the proposed roadway construction. Describe the facility. What is it? Water main? Force main? Cable? Conduit? Overhead electric? Overhead cable? Manhole? Handhold? What's the size? How many? What's it made of?
Examples of entries could be "Cleared", "Pending", "No Conflict". It's suggested to keep the entries determined as "No Conflict" in the matrix so other reviewers will know a perceived conflict has been noted and determined to not be an issue.
Project number. Project description.
That would be you, the person that wrote the conflict matrix.The date the matrix was completed.For ease of discussion the conflicts are numbered, plan sheet numbers are not used because they change from Phase to Phase which has caused confusion in the past.
The date should be on the plans Key Sheet. The phase and plans date should keep everyone working on the same plans.

Recommendations from State DOTs
• Utility conflict matrix:– Track utility conflicts at facility level– Maintain and update UCM regularly– Develop UCM reports for utility companies– Keep UCMs simple– Use 11x17-inch page size for UCM– Start UCM during preliminary design phase– Include data from UCM in PS&E assembly
2-62
Recommendations from State DOTs
• Utility conflict management:– Use document management systems to
support utility conflict management process– Conduct “plan-in-hand” field trips with utilities– Use One-Call to identify utilities early in the
PDP– Use RFID tags for damage prevention during
construction– Provide 3-D design details to utility owners
early in the design phase
2-63
Recommendations from State DOTs
• Other:– Involve stakeholders in review of utility
conflicts and solutions– Develop effective communications with utility
owners regardless of reimbursem*nt eligibility – Provide training to utility coordination
stakeholders
2-64
Prototype UCM Development
• Many states use tables or spreadsheets to manage utility conflicts
• Different categories of data tracked• Wide range of styles and content
– 26 sample tables received– 144 different data items in total– Range of data items per table: 4 – 39– Average number of data items per table: 14– One size does not fit all– Different ideas about “consensus” tables
2-65
Prototype UCM Development
• UCMs are not simple 2-D table products• Prototype 1: Compact, standalone UCM
– Low number of data items– Spreadsheet (MS Excel)– UCM spreadsheet is the product
• Prototype 2: Utility conflict database– Formal data model (ERwin)– Tested in MS Access– Enterprise database support (e.g., Oracle, SQL
Server)– UCM is one of many queries/reports possible
2-66
Prototype 1: Development
• Steps to select data items for standalone UCM– Analyze sample UCM data items– Analyze survey results (conflict data)– Analyze survey results (facility data)– Consolidate/rank data items– Identify data items to include in UCM
• Result: reduced data items from 144 to 25
2-67
Prototype 1: Utility Conflict Matrix
• UCM header: 8 data items• UCM body: 15 data items• MS Excel format• Includes drop-down lists
