2013 Michigan Bridge Conference Bridge Field Services Update

2013 Michigan Bridge Conference Bridge Field Services Update Matthew J. Chynoweth, P.E. March 20, 2013

DEQ Bridge Painting Consent Order Update:

In second year of Consent Order for Bridge Painting Typically CO’s last two years before terminated DEQ attended 2013 Bridge Paint School Over 50 attendees, mix of MDOT, Local Agency and

Consultant groups Currently working with DEQ to update hazardous

management training through DEQ webinars and meetings with Compliance Specialists

Pay special attention to bridge paint project while under order

While the CO is “mild”, noncompliance could still result in major implications and fines.

Bridge Construction Inspection Training Updates:

Bridge Deck Inspection Beam erection, reinforcing steel placement Shear developers, haunch grades, positive and negative

moments Pour sequencing, finishing machine set up (Bidwell), forming,

placing and curing BOHIM 2007-02

Form 1138 Reinforcing computations Form 1131 Depth checks Form 1125 Permit to Place Form 1174B Report of Concrete Placed Bridge Deck Construction Checklists

706 Standard Specifications


Additional emphasis this year on the following: Setting haunch grades Pour Sequences and negative moment regions Stay-In-Place forms Cold Weather Protection 706.03.J

Below 50 degrees but above 40 degrees per National Weather Service use Ordinary Protection (tarpaulins, straw, other approved methods)

Below 40 degrees for more than 8 consecutive hours apply low temperature protection (insulated forms, heating and housing) to maintain concrete/form temperature of at least 40 degrees

If temp falls below 15 degrees heat and house superstructure concrete Concrete temperature of 40 degrees is critical for curing period


Bridge Rehabilitation Construction Bridge Scoping Substructure patching and repair Construction of new bearing surfaces Pin and Hanger rehab and replacement Structural steel repairs Concrete beam repair Expansion joint design, theory, replacement and installation Bridge deck patching Concrete deck rehab, LMC and SFMC overlays Epoxy overlays and healer sealers Total deck replacement

Welded Pile Splice Update: BOHIM Field Splicing of Steel Foundation Piles Special Provision to replace subsection 705.03.C.2.d Special Provision for Quality Control Plan for Welding

Pile Contractor QC plan Updated 1161L for MDOT QA

Field Manual for Pile Welding Comprehensive reference document for field welding

Post Construction critical needs:

23 CFR 650.315 states: (c) For existing bridge modifications that alter previously recorded data and for new bridges, enter the SI&A data into the State or Federal agency inventory within 90 days after the completion of the work for State or Federal agency bridges and within 180 days after the completion of the work for all other bridges. This includes taking vertical underclearance

measurements, and sending form to Bridge Management Unit for SI&A update.

Currently working on updates to MDOT Project Scoping Manual for evaluation of ABC/PBES techniques with respect to: Site and Structure considerations Work zone Safety and Mobility Cost Technical Feasibility Seasonal Constraints and Project Schedule Environmental Issues


Achieve industry buy-in Will be developing ABC workshop with industry in late 2013 Allow time to become comfortable and knowledgeable

using PBES.

Think like a Contractor Consider equipment capabilities and capacities Means and methods to be more thoroughly developed

during the design phase Blur the line between design and construction

Plan a Program of Projects Build Momentum – a clear signal to the industry that the

business model is changing.


Challenges: Lack of Knowledge and Experience

Detailing Connections Tracking Durability Designing Curvilinear Geometry Accounting for Negative Moment Continuity

Availability of Precast Contractors Designing element size for transport and site

erection (limiting weight) Contractor Proposing to go Back to CIP After Award


Three bridge slide projects proposed for 2014 US-131 over 3 Mile Road in Grand Region M-50 over I-96 in Grand Region M-100 over RR in University Region

Others being discussed in MDOT Bridge Committee

meetings

MDOT ABC Policy Update: GRS Bridges

Pilot project in design Phase in Ionia County: Keefer Hwy over Sebewa Creek

MDOT incentivized by providing Geotechnical

Load Rating Plan of Corrective Action Update Technical Assistance for Load Ratings Metrics 13 and 14 MAP-21 and Expanded NHS Element Level Inspection – What is it? MiBridge Update Questions

Load Rating Plan of Corrective Action

Local Agencies had over 1600 bridges to rate as part of the Tier 1 requirements

Tier 1 was comprised of bridges with no load ratings Tier 1 Load Ratings were due on December 31st,

2012

% of Local Agency Ratings Complete by Date


Tier 2 is comprised of bridges in poor condition Load Ratings must be reviewed or updated to

account for the poor condition Tier 2 Load Ratings are due on December 31st,

2014 Tier 2 was already 20% complete on January 1st Remember that as this Tier is tied to inspections, it

likely makes sense to include the load rating with the inspection rather than waiting until December of 2014

Technical Assistance for Load Rating

Bridge Advisory 2012-01 July 2012 MBIS/MBRS Update and Coding Revisions

Bridge Advisory 2012-02 October 2012 Guidance for “Judgment” ratings

Technical Assistance for Load Rating

Bridge Load Rating Program Support with MTU Center for Technology and Training

2012 Accomplishments 6 Virtis Training Workshops 3 Webinars Over 240 technical assistance cases

2013 Plans User Needs Survey 1-2 additional Virtis Workshops Webinars on advanced load rating topics Continued technical support and license facilitation

Metrics 13 and 14

Metric 13 – Conditional Compliance due to the Load Rating action plan being underway

Metric 14 – Post or Restrict In the 2011 Review, there were 56 Structures with

Item 41 coded “B” In the 2012 Review, there were 60 Structures (taken

December 17th, 2012 Currently there are 183 Structures coded “B”

MAP-21 and Expanded NHS

Asset Management MAP-21 requires a Risk Based Asset Management

Plan 18 month deadline for FHWA to define the process

and 18 month transition period Performance Goals Penalties applied is more than 10% by deck area of

the NHS is Structurally Deficient for the prior 3 years 18 month deadline for FHWA to establish additional

performance measures and standards and 12 month for States to set targets

MAP-21 and Expanded NHS

Expanded NHS Local Agencies have 151 NHS Structures which is

5.5% by Count or 5.4% by Deck Area Statewide The Local NHS Structures are owned by 26 different

agencies Element Level Inspection Beginning in October of 2014, all NHS bridges must

have Element Level Inspection The Federal SI&A Manual will need to be updated

Element Level Inspection

National Bridge Inventory general condition ratings assigned by inspectors for major components

FHWA reviewing whether Element Level Inspection should be extended to Non-NHS bridges

MDOT is currently updating the Michigan Element Inspection Manual (Pontis Manual) to conform with the AASHTO Guide Manual



NBI Item Inspection Fair Condition Do nothing - $0.00 Rehabilitate all of the

bananas - $3.00 Element Level Inspection

7 bananas 4 good bananas 3 rotten bananas

Rehabilitate only the rotten bananas - $1.28

MDOT collects both NBI and Element level data

NBI data Network or System level

analysis Monitoring Network Goals Information for high level,

executive, legislature, transportation commission

Element level data Project level analysis Prioritizing bridge projects Managing bridge elements Information for bridge

engineers and practitioners Element level data still requires

a needs indicator

MiBridge Update

MBIS and MBRS are being combined into one system

Display and Entry of SI&A Data and Scour Action Plans in MBRS – Estimated April, 2013

Update for new Element Level Inspection – Estimated End of 2013 to Early 2014

MBIS and MBRS consolidation complete and MiBridge released – Early 2014
