HISTORY OF ROCHESTER’S BRIDGE PROGRAM

• Program first implemented in 1981Program first implemented in 1981

• PM Work is 100% funded by the City of Rochester (Cash Capital)

• Average annual maintenance contracts are valued at $250,000

• Over 54 Engineers with 13 individual firms in the Rochester Community g yhave been involved in this program over the span of 31 years

GOAL: Prolong the life of the City’s bridgeGOAL: Prolong the life of the City s bridge infrastructure and reduce the need for large capital improvements

DEFINITIONS

What is Bridge Preservation?

A ti t t i th t• Actions or strategies that:

Prevent, delay or reduce deterioration of bridges or bridge elements

Restore the function of existing bridges

Keep bridges in good condition

Extend their life

Source: FHWA Bridge Preservation Expert Task Group

DEFINITIONS

Bridge Preservation Actions

I t d d t d l th d f tl t ti l t b• Intended to delay the need for costly reconstruction or replacement by

taking action on bridges while they are still in good condition, before the

onset of serious deterioration.

• Bridge Preservation encompasses Preventive Maintenance and• Bridge Preservation encompasses Preventive Maintenance and

Rehabilitation activities.

DEFINITIONS

What is Preventive Maintenance?

Pl d t t f t ff ti t t t t i ti b id th t• Planned strategy of cost-effective treatments to an existing bridge that:

Preserves the bridge

Delays future deterioration

Maintains or improves the functional condition of the bridge

• Preventive Maintenance includes Cyclical and Corrective Maintenance

CYCLICAL MAINTENANCE ACTIVITIES

• Activities performed at planned intervals to preserve existing bridge element

or component conditions.

• Bridge element or component conditions are not always directly improved as

a result of these activities, but deterioration is expected to be delayed.

• Typical Cyclical Maintenance Items include:

Bridge Washing

Spot and/or Zone Painting of Structural Steel Elements

Deck Sealing & Overlays

Concrete SealingConcrete Sealing

Bearing Lubrication

INVENTORY MANAGEMENT

I t M t i i hi h d t k th i• Inventory Management is a process in which one oversees and tracks their assets.

• Bridge Inventory is data pertaining to the identification information, classification, t d t i l ti l diti t i l d ti d ti dtype and material, operational condition, geometrics, load rating and posting, and inspections of the bridge.

• There are several ways to track this inventory depending on the owner’s needs:Si l E l S d h tSimple Excel SpreadsheetMicrosoft Access DatabaseBridge Management Software Program

D t b id t l l ti f b id d t• Database provides a central location for bridge data:PhotosInspection ReportsFlag Reportsg pWork OrdersContract Documents

INVENTORY MANAGEMENT

• 1990’s / Early 2000’s - City utilized MS y yAccess to track bridge inventory

• 2008 – City purchased a Bridge Management Software Program toManagement Software Program to track bridge inventory

• City of Rochester utilizes Cartegraph’s BRIDGEview bridge management software program

INVENTORY MANAGEMENT

Advantages of a Bridge ManagementAdvantages of a Bridge Management Software Program:

• Accurately capture and maintain bridge datag

• Proactively monitor overall condition of bridges

T k t d hi t i l b id• Track current and historical bridge information

• Assists with factoring bridge i t i t l b d tmaintenance into yearly budget.

• Reporting features help track bridge data that helps establish

ti i tpreventive maintenance schedules, and accurately determine replacement needs.

PROGRAMMING

• Utilizing the Cartegraph Software Program generate report listing bridges with:• Utilizing the Cartegraph Software Program, generate report listing bridges with:

Element specific deficiencies (condition ratings ≤ 4)Safety concernsCyclical maintenance needsCyclical maintenance needs

• Based on this information, maintenance needs are prioritized

Estimate cost to eliminate deficiencies or perform the cyclical maintenance needs• Estimate cost to eliminate deficiencies or perform the cyclical maintenance needs

• Evaluate and compare needs, associated cost, and available funds

• Develop a list of maintenance repairs to be performed over a 5-year period

Priority is placed on bridges with safety concerns and bridge elements with condition ratings ≤ 4

• 5-year Maintenance Program is a working document that is updated year-to-year based on current condition and needs of existing bridge inventory.
