STRUCTURE EVALUATION SUMMARY

This two barrel concrete box culvert is in fair condition overall. Problems include deterioration of the headwall and wingwall masonry mortar joints, and two utility lines lying in the south barrel and in the upstream channel.

There are several site-related issues, including silt and vegetation growth in the upstream channel which obstructs flow through the south barrel and directs the stream toward the northeast wingwall. This has resulted in sloughing along the north upstream channel bank adjacent to the wingwall, exposing the floor slab of the north barrel and northeast wingwall footing.

Repairs should be made as outlined in this report to prevent the possible development of more serious or costly problems in the future. In addition, a guardrail system should be installed to help improve motorist safety.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 5140-050P

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.
