Appropriate Tools for Maintenance Operations’ Key Role in Hydraulic Infrastructure Asset Management

Maintenance Operations’ Key Role

Maintenance Operations “owns” the pipe for life.

Maintenance gets stuck with

bad construction

MnDOT’s new video cameras, Laser Ring and Digisewer , can detect bad pipe installations

Close to the ground, Maintenance sees what’s out there

Maintenance repairs the failed pipe and wrecked road.

A little background:

HydInfra = Hydraulic Infrastructure

Culvert and Storm Drainage System

Inventory and Inspection Program at MnDOT

HydInfra includes pipes less than 10 foot span.

Disclaimer: HydInfra is not an

Asset Management System

yet.

MnDOT is on the verge of choosing an EAM. (Enterprise Asset Management system)

These slides depict HydInfra functions to be developed in Asset Management.

HydInfra has evolved over 16 years

• 1996 Hydraulics and I.T.: – Hired a database specialist – Coordinated input from 8 Districts + others – Created database with GPS inspections and ArcMap

data access • 2006 Hydraulics and I.T.:

– Major update envisioned Maintenance use – New features address MS4 requirements – I.T. bestowed web access to data

• 2008 Maintenance and Hydraulics and I.T.: – Maintenance adopted HydInfra for “Performance

Measures”

2008 Maintenance’ “Drainage Performance Measure”

• Culvert repairs got funding – Chapter 152 funds – BARC funds

• Accountability – record keeping in HydInfra • More culvert Inspectors from Maintenance • Districts’ culvert inventory is completed • Inspection cycle is established

Maintenance added ideas.

• HydInfra Report: Suggested Pipe Repair Method

• Cost estimate from Repair Method Report improves Districts’ planning and budgeting

Maintenance sparked the “Pipe Suggested Repair Method”

Bad pipes are sorted into Repair Methods from traits

Maintenance developed Statewide Pipe Repairs Cost Estimate

About the Suggested Repairs Report data: Suggested repair method is based on Flowcharts on the HydInfra MBMT webpage http://bridge/Hydraulics/HydInfraforMBMT.html • Pipes included in the Report have Status of Inplace, in Condition 3 or 4 with Repair = Y or N, or null. • Pipes of Material Types other than Steel or Concrete have no repair suggested • Pipes with extensions may not show up in this data set • These repair methods are suggested for estimating purposes and are not a repair decision • Contact bonnie.peterson@dot.state.mn.us with questions about the report Before repairing a pipe many factors must be considered, including: • Hydraulic capacity of repaired pipe – get recommendation from Hydraulics/WRE • Individual pipe’s data should be verified before repair • Additional work may be required, especially mudjacking the voids • Soundness of road – can voids outside of the repaired pipe be adequately filled? • Structural integrity of pipe after repair • Cost reduction of combining repairs for several pipes of one repair method in a project • Cost comparison for repair methods in local area may suggest a different repair method • Cost balance of open trenching (with required pavement repairs) versus other methods • Type and scope of project (reconstruction, overlay, maintenance) may suggest choosing replacement over

repair, or vice versa • Traffic requirements – are lane closures required or are they feasible? • Right‐of‐Way sufficient for repair method • Accessibility for equipment used in repair method • Presence of large rocks prevents jacking • Other repair methods may be appropriate for any pipe, for example, “Grout Joints” pipes might also be repaired

with internal bands

HydInfra data is used by Maintenance and Hydraulics

• Budgeting • Repair planning • Project Pre-design • Reporting for MS4 • Research on Materials • Lifecycle planning - someday

Hydraulics + Maintenance

Friends with Benefits

Good Asset Management requires

Appropriate Tools

Tools for inspection and data access vary by user background

and location

(International development agencies learned this lesson long ago. It took me awhile)

8 Individual MnDOT Districts

act like 8

individual districts

(or maybe 10)

Many, part-time users have a variety of skills

and needs.

HydInfra Data Management Tools

Simple ratings suggest repair needs

Explicit criteria behind the condition ratings Concrete Pipe and Special Structure condition rating guide

Inspection “Flags” allow sorting for problems

Condition Indicators –Needs Repair? –Piping –Cracks –Holes –Deformation –Misalignment –Joints Separated –Spalling/Flaking –Pitting/Rusting –Infiltration

Roadway Indicators –Void in Road –Road Distress –Inslope Cavitation –Erosion/Scour

Not in Condition Rating –Needs Clean? –Plugged –Silt –Standing Water

Pipe Materials & to track lifecycle

Liner HDPE Liner PVC Liner Cured in Place Liner Metal Liner Other

“Liner” materials describe a lined pipe:

Corg. Steel (CSP) Structural Plate Polymeric-Coated Bituminous-Coated

Aluminized Steel Corg. Aluminum (CAP)

Corg. Plastic (HDPE) PVC Perforated Plastic

Timber Other

Concrete

Together condition, flags and material

create solutions.

ArcMap:

Repair Planning

Potential Invert Paving Repairs

behind the map

there is data

What kind of data goes in?

•Project design “Proposed” data (CSV)

•Construction as-builts (we wish)

•HydInfra inspection cycle (TerraSync,

ArcPad)

•Maintenance’ repairs (TerraSync, Excel)

HydInfra Tools and Capabilities

Flexible data input tools for varied skill types

• GPS – Trimble Terrasync for part-time Inspectors – ArcPad field inspection for Metro District

• CADD data export for Hydraulics designers • Excel/Crystal Report for random updates

– HydInfra Input file

• Forms

District Inspectors can inspect with little human support

• Inspection support is web-based – downloads uploads and instructions

• Trimble TerraSync GPS is very forgiving

• Inspectors work from remote Truck Stations

• Some Inspectors process and upload data

TerraSync GPS Import Files Inspector “edits” HydInfra data, saves new record

Reduces duplicate inventories!

Excel HydInfra Input File – “hif-like data” for input from paper inspections

Getting the data out is more important than

getting the data in.

Appropriate Data Out Tools

Data comes out: •Web-based Crystal Reports

– Export to Excel for number crunching

•ArcMap HydInfra Tools – Simplifies GIS data access

•MnDOT Basemap and DNR Quick Tools – Fast setup for background ArcMap layers

•Web-based WRE Map Service – Map and data available to special outsiders

•KML Google Earth – Quick maps and data for the hinterlands

Data line speed – slow or fast?

• Remote Truck Stations can’t use ArcMap – painfully slow updates

• ArcMap for District office people – fast(er) updates

• Web-based Crystal Reports for all regions • Google Earth KML for fast and easy map

Inspectors – wide range of PC skills

• Inspectors may need basic PC training • Inspectors may be skilled with PCs • Most human support is by phone • Annual HydInfra Inspector Training includes

download procedures

How it all might be used

Asset Management Scenarios:

1. Maintenance plans annual pipe repairs 2. Hydraulics’ culvert design for construction

project 3. Maintenance finds shoulder cave-in 4. Heavy rains wash out culvert on remote

highway 5. Metro District hazardous spill

Scenario 1: Maintenance plans annual pipe repairs

• District Key Expert runs web report: “Pipe Suggested Repair Method” • Exports to Excel and “Format as Table” • Selects pipes on highways to be repaired • Sends to Hydraulics group for input • Estimates costs, orders materials, fixes • Or repairs are contracted out

Web-based HydInfra Reports export to Excel

Maintenance selects pipes to repair: Suggested Repair Methods Report

Excel “Format as Table” saves time for Maintenance

Scenario 2: Hydraulics’ culvert predesign for construction project • Winter design work • Aging steel plate culvert • HydInfra shows condition rating and pipe

problems (inspection flags) • Check for pipe video • Fish passage and DNR permit required • Possible culvert upsizing & StreamStats • Materials Lifecycle consideration

HydInfra ArcMap Query Tool export data to Excel, also CADD

Maybe this pipe also has a Video Inspection

• Designer reviews video inspection data

• Video standards at: Asset Management should include space for video inspection data lNASSCO PACP Pipeline Assessment & Certification for video inspections http://www.nassco.org/training_edu/pdfs/pacpcodechart.pdf

Get environmental permits info from MNDNR - Quick Tools in ArcMap

Find MnDot-DNR Permit best practices Questions to MnDOT’s DNR Liaison

Designer gets culvert watershed area from StreamStats

Should we replace the steel culvert with concrete?

Check the

Materials Lifecycle Map

(It doesn’t exist yet but that would be so cool!)

Research Pipe

Materials in ArcMap

Inspection flags show hotspots: Joint Separation

Inspector tells Supervisor HydInfra ID Highway Milepost location

Scenario 3: Maintenance Inspector calls in shoulder collapse

• Pipes2.kmz • SpecialStructures2.

kmz • Structures2.kmz

Supervisor finds location in KMZ

The Supervisor • Runs the Suggested Repair Method Report

• Sends information to District HQ for Hydraulics’

recommendation

• Sends right of way staking request to Surveys

• Repairs pipe as recommended

• Updates pipe in HydInfra with Hif-like data report

Scenario 4: Heavy rains wash out culvert on remote highway

• Roadway is out • FEMA disaster

declared = special forms and records

• Asset Management to find spare parts

Find spare parts and people in Asset Management

• Adjacent District has right-size apron and can deliver today

• Request Metro Maintenance Drainage Crew for help with emergency repairs

• Request HydInfra Inspectors from other Districts for other emergency inspections

Trained Maintenance’ Inspectors can collect other data with GPS

• FEMA flood disaster field records

• Guardrail hits

• Noxious weeds control

• Maintenance has endless needs

Scenario 5: Metro District Hazardous Spill is contained

• Semi-Truck carrying benzene overturns • 1100 feet from Mississippi River • Storm drain outlets to the river

Locate Outfall on WRE’s Map Service Geocortex Map Service for outsiders

Maintenance plugs outfall while

HAZMAT contains spill

Planning for Asset Management

Don’t tell one guy to go make a list of data fields and call that good.

It won’t be.

Developing Asset Management is a process that begins by gathering fresh ideas, then beating the crap out of them in group discussions, to end up with a sleek and efficient set of improvements . . .

I know . . . Maintenance folks are

doers not talkers but . . .

• Asset Management needs good planning • Good planning requires hours of discussion • Once completed it’s hard to change
