Stretching Dollars with Bridge Maintenance Presentation Transcript
NEW YORK STATECOUNTY HIGHWAY SUPERINTENDENTS ASSOCIATION Stretching Your Dollars with Bridge Maintenance August, 2011 Alexandria Bay, New York
Understand how the taxes we pay are returned to us for localprojects. Understand how Federal HBRRP funds can be captured for localbridge maintenance activities. Not everyone uses Federal funds for bridge maintenance. Understand the difference between cyclical maintenanceactivities and corrective maintenance/repair projects. Compare and contrast Federally funded and Locally fundedBridge Maintenance programs.
The Highway Revenue Act of 1956 created the HighwayTrust Fund.Established to financetransportation projects,including the InterstateHighway System.Funded by 18.4 centsexcise tax collected fromthe purchase of everygallon of gasoline.
The Trust Fund pays for multi-year programs for highways,highway safety, and transit through a funding and authorizationbill that governs surface transportation expenditures.The current program: Safe,Accountable, Flexible, EfficientTransportation Equity Act: ALegacy for Users (SAFETEA-LU)expired in 2009 but has sincebeen extended 7 times. The latestextension will expire onSeptember 30, 2011.
There could be another extension to SAFETEA-LU, anentirely new program, or States could be left to fend forthemselves until there is a new authorization bill.A new $339 billion surface transportation bill has receivedthe unanimous support of the U.S. Senate Environmentand Public Works Committee as of July 21, 2011.The name of the Senate Bill is “Moving Ahead forProgress in the 21st Century” or “MAP21”.
Like most Federal Programs, the current spending levels arein excess of the revenue generated by taxes and fees. If spending continues at current levels, there is concern that the Trust Fund will be depleted in the next few years unless stabilized by an infusion of funds from the Federal Government.“A New Direction” Transportation Reauthorization Proposal – House Committee on Transportation and Infrastructure, Page 3, July 2011
For years, Federal funding given to local municipalitiesfrom the Highway Bridge Replacement andRehabilitation Program (HBRRP) had been limited tobridge replacement or major rehabilitation.On January 11, 2002 the Federal HighwayAdministration opened the door for HBRRP funding tobe used for preventive maintenance activities onFederal-aid highway bridges.11. January 11, 2002 Memo King W. Gee, Program Manager to Division Administrators
On October 8, 2004 the Federal Highway Administrationclarified its position on HBRRP funding for preventivemaintenance activities on Federal-aid highway bridges.2“...Timely preventive maintenance and preservation activities arenecessary to ensure proper performance of the transportationinfrastructure...”“...Preventive maintenance offers State DOTs a way of increasingthe return on their infrastructure investment...”2. October 8, 2004 Memo King W. Gee, Program Manager to Division Administrators
Prior to this change inpolicy, local bridges wereoften allowed tosignificantly deteriorateuntil they were eligible toreceive Federal funding forbridge rehabilitation orreplacement.
Metropolitan Planning Organizations (MPOs) were created forurbanized areas with a population greater than 50,000 to assurethat Federal funds are expended using a comprehensive planningprocess.For rural or non-urban areas, NYSDOTis responsible for programmingFederally funded projects.MPOs develop the StatewideTransportation Improvement Program(STIP) which is a list of all transportationprojects in New York proposed forFederal funding.
Owners are required to develop a BridgeMaintenance Program to access HBRRP funds.Approved Bridge Maintenance Programs areeligible for 80% Federal Funding.There is still a 20 % Local Match required.Unfortunately, Marchiselli funds are not available forthis program to assist with the local share.
A strategy for preventative bridge maintenanceactivities that describes: Cyclical Maintenance Activities that will be planned on an annual basis; Corrective Maintenance Activities that will be planned assuming a cyclical maintenance program has been developed and implemented; Approximate unit costs per bridge per activity based on material and type of bridge; Proposed frequencies of each activity; and, Approximate Total Annual Cost of the program.
Programmed routine bridge work that is time dependent and does notaddress immediate bridge deficiencies.Includes cyclical activities such as bridge washing, bearinglubrication, painting, deck sealing, crack sealing, deck overlay, andsubstructure concrete sealing.
Programmed bridge work that does not involve the evaluation ofdifferent alternatives but addresses specific (not necessarily all)bridge deficiencies.Includes joints, bearings, pedestals, bridge seat/pier cap,columns/stems, channel erosion, flooding, drainage, verticaldown, vertical clearance, overload/load ratings, etc.
HBRRP Bridge Maintenance Plans are developed annually by bridgeowners.The MPOs and NYSDOT Regions revise their Regional TransportationImprovement Plans (TIPs) every two years.The STIP is developed every four years with “periodic” updates.The Federal Transportation Plan is an unknown after September 30, 2011if SAFETEA-LU expires.
There are over 17,406 bridges in New York, of which 7,632 are ownedby NYSDOT. 8,587 are locally owned structures and 1,187 are ownedby commissions, privates or others.

Niagara County is located in NYSDOT Region 5 and is a partof the Greater Buffalo-Niagara Regional TransportationCommission (MPO).Niagara County’s Bridge Maintenance Program is funded with80% Federal money.Niagara County tax payers fund 20% the Niagara CountyBridge Maintenance Program.
Federally Fundedbridge Maintenance:Niagara Countytogether with othersworked through ourMPO to allow federalfunds to be used for80% of the cost forbridge preventive andcorrective maintenance.
The Niagara County Inventory of Bridges We believe we have 88 bridges. NYSDOT believes we have 90 bridges. 88 bridges represent 124 bridge spans and an average bridge length of 69’.
PROGRAM DEVELOPMENT HISTORY Maintenance saves money “No washee no checkee!” The Color of Money Federally Funded Bridge Maintenance Bridge maintenance is not a capital expense
Bridge Cleaning began in 2008. The regional strategy calls for biannualcleaning, but we desire annual cleaning. Bridges were cleaned in 2009 and 2011.We had hoped to wash the tops of our better bridges in 2010, but NYS budgetarytroubles pushed the work back into the fall which makes it nearly useless.Our costs initially were about $2000 per bridge but in 2011 we paid about $1000.The competition appears to be fierce so I expect an eventual stabilization of costsat about $1500. We wash about 80 bridges.
Bridge Sealing was performed in 2009. The cycle for this is to be 6years. We extended the scope of this work to include the bridgefascias, seats, back walls, wing wall tops and the undersides of theconcrete superstructure near the stem.This work was combined withcleaning making it difficult to separateout the sealing cost, but $2500 isprobably close. We think that thenon-trafficked surfaces will not needre-sealing in 6 years. If the concretewill not take the sealer we will havebeen proven right.
Bridge Painting was performed in 2009. The cycle for this is to be 12years. We thought we had enough money for four bridges so we bid it witha fifth bridge as a deduct alternate. As it turns out we could have done sixbridges. The painters were hungry that year.The sad thing was that this left us withone bridge to be painted. Of the fivebridges two were total removals. Ourcost was about $15.50/SF for totalremoval, and $4.50/SF for over-coating. The sixth bridge was paintedin July 2011.
Bridge Joints on six bridges were completed in 2010. The contractreplaced or established bridge joints at a cost of about $20,000 per joint.This was funded with unspent ARRA funding.
Asphalt Overlays were completed in 2011. The cycle for this isto be 12 years. This work is complete. Our cost was about$13,000 per bridge. Our bridges tend to be about 40’ clear span.
Bearing lubrication, restoration and replacement contract was let in 2011NYSDOT has been replacing lubricated with elastomeric bearings. The concern isthat we are supposed to account for the forces needed to deform the elastomericbearings and that replacement costs more money than we could get. Our solutionwas to install pressure fittings on the outside of the bearings and inject a corrosioninhibiting and lubricating solution. The lubrication will cost about $1500 per bearing,restoration about $2000 per bearing and replacement about $8,000 per bearing.
Looking Ahead….. Scour Protection project is currently in design. Vertical Down project is also currently in design. Funding for a Superstructure Repair project has been requested.
Selecting our maintenance project candidates: A bridge programmed for replacement does not receive any maintenance work. We will however perform preventive maintenance on bridge programmed for rehabilitation. The County Bridge Spreadsheet: Starting about 2000 we began keeping some of our bridge data (entered by hand) in one spreadsheet for all bridges, and for various purposes. Now we copy and paste the latest WinBolts, selected data only, into the County Bridge Spreadsheet.
Selecting our maintenance project candidates: The County Bridge Spreadsheet we developed uses a series of logical tests such as condition ratings and program status to generate numbers for the bridge categories for the annual Bridge Maintenance Strategy. The spreadsheet also uses logical tests such as element condition ratings, type of construction, year of latest maintenance etc. to flag qualifying bridges for each maintenance program, and to create a list of BINs. The Region reviews the Bridge Maintenance Strategies submitted by the locals, contacts us with questions, discusses our priorities, and later notifies of us which programs will be funded and to what extent.
Lessons Learned: You can develop your program to suit your needs. The application of eligibility rules is not completely rigid. This is particularly noteworthy if you have erroneous ratings. Within limits the funding can be adjusted. You might be allowed to create a new program such as annual bridge washing rather than biannual. Group bridges for cyclical work.
Lessons Learned: Group similar work into one contract. Give the entire scope of work needed some serious thought before submitting an estimate. Where experience is lacking forethought must be multiplied. Keep track of your list of BINs. Since these projects are difficult to estimate the first time, consider using deduct alternates so you can fit the contract based on the bids received to the funding available.
Lessons Learned: The candidates for any of the paving work will be a moving target particularly if your towns pave over your bridges without telling you before or after. Be careful with Inter-municipal agreements for preventive maintenance projects!!! The Agreement process is onerous. It makes the most sense to clean the bridges as soon as possible after the last likely application of salt. Washing and sealing contractors are not familiar with NYSDOT specs and process or federal laws. You have to walk them through it all.
•Access will be a large part of the cost. Lessons Learned: Access will be a large part of the cost. Give thought to whether multiple contractors will have to work on the same bridge at the same time. The inspection effort has to be planned and re-planned. The Bridge Maintenance Strategy is a living document that is revised rather than rewritten every year. Funding is limited so NYSDOT will ask you to prioritize the programs.
•Access will be a large part of the cost. Lessons Learned: Maintain new bridge immediately. This means sealing the concrete as part of the construction contract. Selective repairs of key bridges could give you a “like new” bridge. Crawl then walk then run.
Allegany County is located in NYSDOT Region 6 and is notrepresented by an MPO.No Federal money is used in our Bridge MaintenanceProgram.Allegany County tax payers fund the Allegany County BridgeMaintenance Program.
The Allegany County Inventory of Bridges Allegany County has 125 bridges. Allegany County also maintains 230 Town Highway bridges. A significant portion of the inventory is old or historic.
We don’t waste anything. We recycle our bridges when wecan.The main elements of the former CR 4 Bridge over anabandoned railroad were repurposed for the construction ofthe York’s Corners Bridge over the Genesee River.
Each February, Allegany County contacts each of the Townand Village Highway Superintendents to identify their bridgemaintenance needs.A list of candidate bridges are reviewed by the Public WorksCommittee.Bridge maintenance projects are selected based on needfeasibility and budget.
A key component of the Allegany County Bridge MaintenanceProgram is shared services with the Towns and Villages.The County works closely with the Allegany County Town andVillage Superintendent of Highways Association to executeShared Services Agreements with the Association Members.Allegany County shares engineering, labor and equipmentwith the Towns and Villages.The Towns and Villages provide all of the materials for theirBridge Maintenance activities.
Allegany County DPW has a specialized crew that performs bridgemaintenance and repair activities.In the winter months, this crew is utilized to plow snow and de-ice.Allegany County has only 5 plow trucks. To increase efficiency andmobilization, most of the plowing and de-icing is delegated to the Townsand Villages.
One goal of the Allegany County Bridge Maintenance Program is towash all 125 County bridges and selected Town and Village ownedbridges.
Each Year, approximately50 (County, Town andVillage) bridges arepainted. This is CR-43over the Angelica Creek.This seven panel PrattThrough Truss wasconstructed in 1930.
The painting program involves high pressure washing and anapplication of Alkyd enamel. The enamel is sprayed, brushedor rolled depending on the bridge.The paint system is fairly inexpensive and doesn’t requirespecialized equipment or respirators (unless spraying).
One unique aspect to Allegany County’s Bridge Maintenance Program isthat we own a Under Bridge Inspection Unit (UBIU). This piece ofequipment saves a considerable amount of time and provides the bridgecrew with safe and efficient means of access for maintenance activities.
Bridge Joints are repaired or replaced as necessary.
Bridge scour is a constant problem, especially for the many small,single span bridge culvert structures in the County.The County is able to leverage Federal Emergency ManagementAgency (FEMA) Disaster Mitigation Funds for replacement ofwingwalls and channel stabilization.
The advantages of the Allegany County BridgeMaintenance Program include: The budget is clearly defined – no uncertainty concerningthe MPO’s TIP, the NYSDOT STIP or the FederalTransportation Bill. Low administrative costs – more money for bridgemaintenance activities. There is no waiting for reimbursement.
