STRUCTURE EVALUATION SUMMARY

This two barrel concrete box culvert is in fair condition overall. Problems include deterioration of the masonry mortar joints throughout; deterioration and undermining of the concrete sidewalk along the south end wall; and a moderate accumulation of flood debris at the upstream end of the intermediate wall.

In addition, the stream flow approaches the north barrel, but is blocked by an accumulation of silt and stones which conforms to the surrounding topography. The stream then flows across the upstream end of the intermediate wall and through the south barrel. The flood debris at the upstream end of the intermediate wall is promoting scour and has exposed up to 1'-6" of bedrock in the south barrel. The downstream channel at the south barrel is restricted by a rock formation and vegetation.

Corrective measures should be taken as outlined in this report to help prevent the possible development of more serious or costly problems in the future. In addition, consideration should be given to installing a guardrail system to help improve motorist safety.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 5140 012P

226 PRIORITY OF IMPROVEMENT C

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

B (Major) - Structure exhibits severe deterioration, presents a safety hazard, or is designated a high priority due to age and/or condition.

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.
