STRUCTURE EVALUATION SUMMARY

This concrete slab bridge is in good condition overall. Problems noted include adhesion failure of several joint seals, resulting in leakage and heavy staining of the bent caps below; the joints seals over Bents #5 and #13 are depressed up to 1" below the deck. Other problems include vegetation growing from the bearing seats at Bent #2 and #10, and deteriorated double yellow centerline striping. Corrective action should be taken as outlined in this report to prevent the possible development of more serious or costly problems in the future.

In addition, some concrete deterioration was observed at the Bent #2 and #13 caps. The Bent #2 cap exhibits a large spall with exposed rebar; the rebar should be cleaned and sealed with an approved coating to prevent corrosion and further damage to the surrounding concrete. the Bent #13 cap has several areas of spalling and delamination; repairs are not currently deemed necessary, but this condition will continue to be monitored during future inspection cycles.

It should also be noted that the deck slab is exhibiting cracks in several locations. This condition is not considered a serious problem at this time, but will continue to be monitored during future inspection cycles.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 5280-004P

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.

(*Includes typical contract costs for mobilization, traffic control, and design/construction engineering; but does not include detour bridges, work beyond the bridge limits, or work not listed above.

FIELD INSPECTION REPORT STRUCTURE NO. 5280-004P

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.
