STRUCTURE EVALUATION SUMMARY

This concrete tee-beam bridge remains in fair to poor structural condition due to extensive concrete deterioration throughout the deck, superstructure, and substructure. The bridge is scheduled for rehabilitaion in the near future under Project PRA-NAMA 17(1).

It should also be noted that several wires for electric lighting inside the structure are exposed. This condition could pose a safety hazard, and should addressed in a timely manner. In addition, debris buildup is present at several vent locations inside the structure along the north side retaining wall; this debris should be removed.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 3400-036P

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. 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 the recommended actions will be combined with similar work being performed on other structures.

Structure is scheduled for rehabilitation in the near future under Project PRA-NAMA 17(1).

FIELD INSPECTION REPORT STRUCTURE NO. 3400-036P

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.

STRUCTURE EVALUATION SUMMARY

This continuous concrete tee-beam bridge remains in fair to poor structural condition due to extensive concrete deterioration throughout the deck, superstructure, and substructure. Spalling of the concrete is ongoing and has exposed rebar in several locations, and the exposed rebar has now begun to corrode. In view of the extent of the existing deterioration and the potential for loss of load capacity over time, the park has been informed that this structure should be programmed for rehabilitation in the near future. The rehabilitation would involve removing all unsound concrete, cleaning the exposed rebar, replacing or splicing any rebar having significant section loss, and placing new concrete to the original dimensions. In addition, as a measure to prevent further water intrusion into the deck, the existing wearing surface should be removed, a waterproofing membrane installed, and a new wearing surface placed.

Additional problems include moderate to severe deterioration of the deck and sidewalk expansion joints, missing light posts, and exposed wires on the utilities inside the structure. The missing light posts and sidewalk expansion joints should be repaired immediately, as the exposed anchor bolts and broken and dislodged cover plates present a hazard to pedestrian and bicycle traffic.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 3400-036P

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.

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

If the recommended wearing surface replacement is not programmed in the near future, the deteriorated areas along the centerline should be patched as an interim measure, and the existing wearing surface saw cut and sealed over the joints between the spans/panels. The estimated cost for this work is .

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.

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.
