TRB Structures Workshop: Steel Bridges – Evaluation and Rehabilitation for Safety (W-5)

Monday, June 2, 1:00–5:00 pm
Objective:
Current bridge funding levels are inadequate to replace the quarter of our nation’s bridges that are classified as structurally deficient or functionally obsolete. Faced with budget constraints and an aging infrastructure, those responsible for bridge safety are challenged to maintain and preserve our nation’s bridges, of which almost half built prior to 1960 are steel. This challenge will be met by developing better evaluation and rehabilitation methodologies so owners can maintain and preserve their bridge inventories under increased funding constraints. This session is cosponsored by the Transportation Research Board (TRB) Steel Bridge Committee (AFF20) and Dynamics and Field Testing of Bridges Committee (AFF40).

Design and Construction Monitoring of Structural Foundations - Best Practices and Pitfalls Workshop (W-8)

Monday, June 2, 1:00-5:00 pm
Instructor: Jerry Dimaggio, FHWA
Structural foundations (shallow and deep foundations) for surface transportation structures continue to present one of the most challenging tasks to design and construction specialists in both private and public professional practice. Current trends like innovative contracting, risk management, limit states design (LRFD) and accelerated construction have further raised the bar for geotechnical, structural and construction specialists in order to meet project development and delivery demands on time and within cost estimates. These features are consistently on the critical schedule path, have significant costs, and are very risk prone to contract overruns and contract disputes.

The goal of this session is to share Best Practices to ensure future project success based on the presenter’s 35 years of international experience with design and construction of infrastructure features.

The following topics are addressed in this workshop (all design related material is presented based on AASHTO LRFD Specifications, 4th Edition 2007):
•Subsurface Investigation
•Communication between Geotechnical, Structural, Hydraulic and Con
•Foundation Selection
•Design Process and Procedures (structural and geotechnical)
•Extreme Event and Hazard Considerations
•Plans, Specifications and Contracting
•Construction Monitoring and Inspection

SSPC Coatings Workshop (W-9)

-20-Year Performance of Bridge Maintenance Systems, J. Peter Ault, P.E. and Christopher L. Farschon - Elzly Technology Corporation and Corrpro Companies

In 1986-1987, New Jersey DOT applied forty-seven (47) different coating systems to various spans of the Mathis Bridge. Each experimental system was applied to a complete span comprising approximately 4,000 square feet of steel. Experimental coating systems included metallizing, various zinc-based systems, various levels of surface preparation, and several overcoating strategies (e.g., alkyd over a hand-tool cleaned surface).

The paper will present the results of an inspection conducted in 2007, nominally 20 years after the initial coating application. The inspection showed varied service lives associated with the different coating systems. Some of the systems were in excellent condition after 20 years while others had completely broken down. In addition to the present condition of the test spans, the paper will review the historical performance of the various coating systems as well as the applied cost. Finally, several important implications for maintenance planners will be presented. These will include cost-benefit calculations and risk-reduction strategies.

9:00-10:00
-Corrosion Mitigation For Steel Bridges: New Construction – Rapid Cure Polyaspartic Coating Systems Maintenance: High Ratio Calcium Sulfonate Coating Systems, Dr. Michael O’Donoghue- ICI Devoe Coatings

In today’s world of high performance coating systems the current milieu of multi-coat systems based on hard film formers provides some outstanding systems for new construction. Part A of this presentation outlines some of the best and most rapid curing systems available based on zinc, epoxy, polyurethane and polyaspartic coatings.

For maintenance painting of bridges Part B of this presentation describes the successful use of an innovative high ratio calcium sulfonate coating system to solve corrosion problems in crevice corroded structure-critical connections and solve the problem of frozen bearings. Case histories and chemistry will be used to highlight the effective use of the technologies described.

10:15-10:45
-One Hundred Years of Paint Performance: Fact or Fiction?, Eric S. Kline, PCS - KTA-Tator, Inc.

Steel bridge painting is in its infancy as bridge construction extends back thousands of years. In those millennia the first bridge made of iron was built in 1779. The first steel was not used in a bridge until 1828. Some coated painted bridges are already over 100 years old. Can modern coatings protect steel bridges for the next hundred years? The author discusses how to achieve 100 years of service life using current materials and offers recommendations for research to improve the performance and economics of steel bridge painting.

10:45-11:15

-Concrete Bridge Coatings in Kentucky: Progress in Lab and Field Testing Results
Derrick Castle and Dee L. McNeill - Kentucky Transportation Cabinet and The Sherwin-Williams Company

The continuing increase in usage of concrete structures, continued aging and deterioration of existing structures, and ever increasing restrictions on the manufacturing parameters of coating systems are evidence that re-examination of the applicability and performance of protective coating systems for concrete structures is long overdue. The Kentucky Transportation Cabinet and the University of Kentucky, Transportation Research Center have partnered with manufacturers in the coatings industry to evaluate selected coating systems. The main objective of this project was to evaluate performance properties of various commercially available thin film coating systems for use on concrete.

11:45-1:00 Lunch

2:00-2:30
-Visual Coating Condition Guide for NBIS Type Inspections, Stephen B. Karl, P.E., Greenman-Pedersen, Inc. (GPI)

This session explores a potential solution to linking the knowledge and practices of coating evaluators and bridge safety inspectors via the introduction of an inclusive visual coding guide that can be integrated with a state DOT’s existing Bridge Management System.

Most state DOTs maintain a comprehensive Bridge Management System as a tool in allocating resources to the inspection, maintenance, rehabilitation and replacement of bridges. These systems typically accept, store, update and report data on the physical and operating characteristics of bridge structures in the DOT’s inventory. Most systems pay little to no attention to the existing coating systems on steel bridge structures. Providing the key link between the two traditional disciplines of coatings specialists and bridge safety inspectors is a necessary task to fill this gap in data reporting. Better data reporting will provide the opportunity for the state to cost-effectively repair the protective coatings prior to requiring complete replacement, thus extending the life and protection of the steel substrate. This paper describes work performed with multiple state and local DOTs to develop paint coding guides that fit the specific needs of these clients’ Bridge Management Systems. The programs discussed reduce the subjectivity in the evaluation process, and provide a coatings management tool.

FHWA Accelerated Bridge Construction/ Highways for Life Workshop (W-15)

Wednesday, June 4, 8:00 am-5:00 pm
Congestion affects our productivity, mobility and safety; and it increases the costs of doing business. Faced with an aging infrastructure, we need better, less expensive and quicker methods to deliver projects in infrastructure renewal. Large construction projects designed to improve worn-out and outdated roads and bridges compound traffic problems during lengthy construction periods. Today’s motorists want high quality, longer-lasting highways and bridges, but they want any construction-related activity completed as quickly as possible. To that end, the Federal Highway Administration has been promoting and implementing accelerated bridge construction through the use of precast and prefabricated bridge elements and systems using high performance materials.

This workshop will provide information on the state of the art practices of the Accelerated Bridge Construction Technology, including information on how by using innovative prefabricated bridge technologies and innovative equipment and contracting strategies rather than conventional techniques, we can achieve our goals of rapid onsite construction with minimized traffic disruption, improved safety and constructibility, and improved durability, and at competitive construction costs and ahead of schedule. The workshop will include presentations on accelerated bridge construction techniques, equipment and details. Details of the new FHWA Manual entitled “Connection Details for Prefabricated Bridge Elements and Systems” will be presented.

1) MacArthur Maze Tanker Fire/ Bridge Collapse, Barton Newton, California State Bridge Maintenance Engineer

In the early morning hours of Sunday, April 29, 2007, a tanker truck hauling 8,600 gallons of gasoline overturned, burst into flames and severed a critical link in the transportation network of the San Francisco Bay Area.

As the fire raged on the MacArthur Maze interchange near Oakland where Interstate Highways 80, 580 and 880 intersect, the California Department of Transportation (Caltrans) responded to protect the public and to assess the damage, re-route traffic and initiate an accelerated repair and reconstruction plan.

Like previous disasters such as the 1989 Loma Prieta and 1994 Northridge earthquakes, this tanker truck fire and subsequent bridge collapse tested Caltrans’ emergency readiness and ability to respond to a major disruption of the Golden State’s transportation system.

Caltrans delivered, reopening one of the damaged connector ramps (the East Bay Viaduct) in eight days and rebuilding nearly 200-feet of the bridge (Distribution Structure) that collapsed in less than one month.

This presentation will provide an overview of the response and recovery efforts employed by Caltrans by identifying the amount and severity of the bridge damage, initiating repairs and restoring traffic service as quickly as possible.

2) I-95, Craig J Beissel, PennDOT
This presentation will talk about the events causing the failure and closure of I-95, the repair scheme, coordination and timeframe to begin and complete the repair, the coordination between all involved parties, repairs to other nearby piers and follow-up inspections.

3) Dillerville Road Over Amtrak Accelerated Bridge Construction, Harivadan Parikh, PennDOT; Greg Burkhart, J.D. Eckman, Inc.

The Concept was accelerated bridge construction using prefabricated system for the substructure and P/S box beams and removal of the existing superstructure using Gantry system.

4) Bradford Bypass, Section C09 – Pile Foundation Design and Detailing for Skewed Bridges Built with Half-Width Construction

This presentation discusses the issues that may arise when designing, detailing, and constructing pile foundations for substructure units that are skewed and built with half width construction. This discussion will focus on the basic considerations for determining the typical section of the superstructure to accommodate construction phasing and temporary shoring, tips for laying out a constructible pile pattern, considerations to avoid interferences of battered piles, and strategies for implementing pile pattern modifications during construction.

5) Million Dollar Bridge Phased Construction, Ahmad Ahmadi, SAI

The Million Dollar Bridge is a 5-span viaduct carrying US 220 over the Juniata River, Norfolk Southern mainline tracks and SR 1010 on the eastern edge of Huntingdon Borough, Huntingdon County. The viaduct consists of a 4-span unit over the river and railroad tracks, while a simply-supported single-span unit spans SR 1010. The support skew angles vary from 55 degrees to 39 degrees. The structure was built in 1948 and carries approximately 10,200 vehicles daily. The existing width is 37’-0” curb-to-curb and 44’-7½” out-to-out, which includes 3’-9” wide sidewalks on each side.

Virtually no work has been performed on the bridge since its original construction. Consequently, major repairs to the structure were needed. Design work on rehabilitating the structure began in 1995. However, with input from the local community seeking expansion of the 3-lane corridor to 5-lanes, the project became delayed due to funding and environmental constraints. With the condition of the bridge reaching a critical point – either rehabilitate or else loose the bridge altogether – and with the added realization that funds were not available to widen the corridor, the decision was made to undertake a $11,000,000 major rehabilitation effort. Due to high traffic volumes and the lack of any acceptable detour route, two lanes of traffic had to be maintained during daylight hours. Controlling one lane of traffic through the work zone in the remaining hours with temporary traffic signals and working at night was permitted. This construction scheme results in third-width construction and very tight work areas for the contractor. The project is scheduled to be completed in Fall 2009.

6) East Brady Bridge community Involvement/ Environmental Issues, James Andrews, PennDOT

The project was the replacement of an existing four span through truss with a new structure on a new alignment. The project is located in Bradys Bend Township, Armstrong County and East Brady Borough, Clarion County and carries SR 68 across the Allegheny River.

Due to the project’s impact on the local community, the Department utilized a Community Advisory Committee (CAC) to assist in the development of a preferred alignment and selection of context sensitive items to be incorporated into the project. In addition, there were several T&E species located in this section of the river that required extensive coordination by the Design Team.

The construction of the project involved some techniques not used in the District before, such as a cooling system placed in the tremie concrete for the piers; constant coordination with environmental agencies due to T&E species; and issues with bridge demolition.

The project was let for construction in 2006 and completed in 2007. KCI Technologies, Inc. of Mechanicsburg, PA was the Design Consultant, and Brayman Construction, Inc. of Saxonburg, PA was the general contractor. The project cost was approximately $16 million.

7) Emergency Design Build, Moderators: Troy Pritts, PennDOT District 12-0 Design Project Manager, Dave Fasiczka, PennDOT District 12-0 Structure Control Engineer
