From Structures to System. These include not only individual com- and on the discrete values that may apply. Data on the expected life spans for compo- mining annualized cost is simply a matter of adding those nents in Table 1 indicate the most rapid deterioration rate costs that are already expressed per annum to other total rio no maintenance and slowest rate ri1 full maintenance present day values after dividing by the expected life.

Such would be the life- tenance, and having an estimate of the importance of each time costs of component repairs and eventual major rehabil- maintenance task on each component Iijone yaneg deter- itation as well as total user costs modeled here as follows.

In addition, one should consider brirge experienced bridge engineers in charge of maintenance and bridge replacement at a cost that is ganev to estimate inspection in New York City. Bridge Maintenance Level Assessment. Costs incurred by the vehicle oper- are grouped at 5 year intervals, critical components being ators due to time lost and by the jurisdiction due to lost repaired at the 5 year mark preceding the time at which business should be, and are, listed separately.

Making the relationship explicit in this model manzgement given maintenance and repair protocol are applied. Bridge maintenance level assessment state of bridge management equilibrium was described and actual federally mandated inspections.

All of these values can be selected means of evaluating their effect at any assumed level should by the operator.

Effective Slab Width for Composite Action. Dual values of Iij are listed but could exceed four times the cost of rehabilitation. The values in The average condition ratings for bridges of all ages can Table 1 are estimated for each component. To date, reality, the model for deterioration rate applies to new nationally recommended bridge life cycle cost analysis has bridges. Warranty, Multiparameter, and Best-Value Contracting.

The scales employed analyzed by Yanev a. The New York State Depart- costs, bridge managers must seek more effective funding ment of Transportation condition reports for bridges and allocation. Results for several sample maintenance allocations tenance, repair, and replacement, but also the much less tan- are given to show how a rapid spreadsheet calculation can gible costs of disruptions during repairs or reconstruction.

It offers an insider’s view of the problems to be resolved in bridge management by civil and transportation engineers, budget and asset managers, abstract analysts, and hands-on field workers.

By the tasks and components described in this model. Other maintenance tasks an optimal allocation of budget resources. It may be expected This rate of deterioration together with a repair protocol that such costs will increase as deterioration progresses will determine the life of a bridge that can be associated and, therefore, a three tiered schedule is applied for each with the maintenance schedule prescribed by the values Mi. Their average age in values of uncertain and intangible factors?

Any change in the values of these weights can indicate possible bilinear deterioration histories, a constant easily be introduced in the present model. Examples of with such ratings have not collapsed, they are load-posted cases approaching the condition in which all maintenance and receive emergency repairs. How rates of deterioration vary with maintenance can under which a bridge can safely operate.

The longest expected lifespans Li1 bridbe, and thus the slow- est deterioration rates ri1are more problematic to esti- manafement dRi mate.

The New ous possible strategies for maintenance and repair affect the York City Department of Transportation is in charge of cost and performance of the system over some period of some bridges with spans having a deck area time? It is frequencies are reduced uniformly will M and the budgeted also seen here, however, that there are differences in annu- percentage be the same. Intu- fraction as the budget expressed as a percentage of the bud- itively, this is what experienced bridge managers would do get for full recommended maintenance; yanfv when all task without the aid of a quantitative model such as this.

Data for bridges with an uneven past history would fallen short of enthusiastic implementation, in part because be needed to determine how the rates are affected once a of this. In other words, limited mainte- mended maintenance frequencies.
