STRUCTURE EVALUATION SUMMARY

This steel beam bridge is currently in poor condition due to decay and deterioration of the transverse timber deck planks, longitudinal runners, and railings. Additional problems include soil and debris accumulation on the deck surface and bearing seats; ponding of water at the approaches; and paint deterioration and rusting of the steel beams and diaphragms, with minor section loss evident in some locations.

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 this bridge is scheduled for rehabilitation in the near future under Project NP NERI BMS(1). The scope of work includes cleaning and painting of the structural steel, and replacement of the timber deck and railings. The new deck will be a nail-laminated type, and the new railing will meet current safety standards. In addition, a pedestrian railing will also be installed to further improve visitor safety.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 4780-003P

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.

PRELIMINARY ESTIMATE TOTAL* :

(*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. Estimates are approximate and are for preliminary planning purposes only; they should not be used as a complete or final engineers estimate.)

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

Existing paint on structural steel is likely lead-based and may require special environmental protection measures for removal.

FIELD INSPECTION REPORT STRUCTURE NO. 4780-003P

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.
