STRUCTURE EVALUATION SUMMARY

This double barrel concrete box culvert is in fair condition overall. Problems include a moderate accumulation of drift in the north barrel, which has diverted the stream flow into the south barrel and caused minor scour; the scour has exposed the downstream end of the barrel floor. In addition, there is moderate scaling of the south barrel floor slab with exposed rebar, minor deterioration of the headwall and wingwall masonry mortar joints, and mortar missing between the masonry and concrete floor slab at the upstream end of the north barrel.

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, consideration should be given to installing a guardrail system over the structure and approaches to help improve motorist safety.

Since the previous inspection, the mile marker in the west shoulder has been replaced, and a missing stone at the downstream end of the south wall of the south barrel has been replaced.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 5140-051P

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.

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

N

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.

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.
