STRUCTURE EVALUATION SUMMARY

This three-span multi-beam prestressed concrete bridge is in fair to poor condition overall. The main problem is delamination and spalling with exposed rebar throughout the beams, diaphragms, pier caps, and east abutment breastwall, with exposed prestressing strands on several beams. This deterioration continues to progress, and of particular concern is the moderate to severe deterioration of the ends of the Center Span Beams #2 through #4 at the East Pier, as these beam ends provide the bearing area for their adjacent East Span beams. Due to the redundant nature of the structure, the deterioration is not considered sufficient to reduce the load rating or the expected life of the bridge. However, repairs to the deteriorated concrete should be made in the near future in order to prevent further deterioration and a possible loss of load capacity. The deteriorated concrete should be removed, the exposed rebar and prestressing strands cleaned and coated with an approved protective sealant, and new concrete placed to the original dimensions.

Additionally, the delaminated concrete could potentially spall and fall onto traffic below. For this reason, loose concrete on the beams and diaphragms above traffic lanes and on the pier caps adjacent to the traffic lanes should be removed immediately.

Furthermore, widespread cracking of the deck underside with efflorescence is likely indicative of water intrusion through the deck concrete. The deck surface should be sealed to prevent further intrusion and slow the rate of deterioration of the concrete. These and other repairs should be made as outlined in this report to prevent the possible development of more serious or costly problems in the future.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 3300-003P

A (Critical) - Structure is closed, in imminent danger of collapse, or presents a critical safety hazard.

B (Major) - Structure is seriously deficient or presents a safety hazard, but can remain in service at reduced loads or with frequent inspections.

C (Moderate) - Structure is deficient, functionally obsolete, or requires substantial repairs to prevent a serious deficiency or unsafe condition.

D (Minor) - Structure is generally in good condition. Preventative maintenance may be required.

E (Special) - Structure is under construction or reconstruction.

FIELD INSPECTION REPORT STRUCTURE NO. 3300-003P

G = GOOD (CODES 7 - 9) F = FAIR (CODES 5 - 6) P = POOR (CODES 0 - 4)

CONDITION RATING CODE EQUIVALENTS FOR SUB-ELEMENTS

SERIOUS CONDITION - loss of section, deterioration, spalling, or scour have seriously affected primary structural components. Local failures are possible.

Fatigue cracks in steel or shear cracks in concrete may be present.

CRITICAL CONDITION - advanced deterioration of primary structural elements. Fatigue cracks in steel or shear cracks in concrete may be present or scour may have removed substructure support. Unless closely monitored it may be necessary to close the structure until corrective action can be taken.

“IMMINENT” FAILURE CONDITION - major deterioration or section loss present in critical structural components or obvious vertical or horizontal movement affecting structure stability. Structure is closed to traffic but corrective action may return structure to light service.

FAILED CONDITION - out of service; beyond corrective action.

CONDITION RATING CODES FOR ITEMS 58 - 62, 222, 223

NOT APPLICABLE

EXCELLENT CONDITION

VERY GOOD CONDITION - no problems noted.

GOOD CONDITION - some minor problems.

SATISFACTORY CONDITION - structural elements show some minor deterioration.

FAIR CONDITION - all primary structural elements are sound but may have minor section loss, cracking, spalling, or scour.

POOR CONDITION - advanced section loss, deterioration, spalling, or scour.
