STRUCTURE EVALUATION SUMMARY

This timber beam structure is in good condition overall, but has some problems that need attention. These include deterioration of the substructure masonry mortar joints; undersized wingwalls at the west abutment; erosion of the embankment at both approaches; broken timber planks at the west approach ramp; erosion of the east channel bank;

moderate soil accumulation between the deck planks and at the bearing seats; a missing anchor plate and nut on one rail post; and broken reflectors on the ends of bridge railings.

Corrective measures should be taken as outlined in this report to prevent the possible development of more serious or costly problems in the future. It should be noted that the bridge may be scheduled for repairs in the near future under Project NP NERI BMS(1).

It should also be noted that the structure is too narrow to accommodate 2-way traffic, and that the east approach is located on a sharp turn. However, these geometric problems are not considered serious in view of the low speed and volume of traffic.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 4780-001P

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.

REMARKS: Cost estimates assume that the recommended actions will be combined with similar work being performed on other structures.

FIELD INSPECTION REPORT STRUCTURE NO. 4780-001P

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.
