STRUCTURE EVALUATION SUMMARY

This concrete box girder bridge is in fair condition overall. Problems include areas of spalled concrete with exposed rebar on the underside of the deck overhangs, cracking with efflorescence and delaminated concrete on the north pier, spalling with exposed rebar on the south pier, clogging of most deck drains with soil and debris, trees growing against the box girder at the south pier, and an open light fixture with exposed wiring at the south approach. It should also be noted that the neoprene bearing pads at both abutments are deteriorating, but this condition does not appear to be causing any distress to the structure. Since the previous inspection, the north approach and railings have been reconstructed, and tree limbs in the channel and against the south pier have been removed.

Corrective measures should be taken as outlined in this report to prevent the possible development of more serious or costly problems in the future.

CONDITION ASSESSMENT:

AARON IMMEL, P.E., FIELD TEAM LEADER

REPORT REVIEW:

MARCUS MILLER, P.E., LEAD STRUCTURAL ENGINEER 703-404-6252

REPORT APPROVAL: DATE: 7/30/10

GEORGE CHOUBAH, P.E., INSPECTION PROGRAM TEAM LEADER 703-404-6244

FIELD INSPECTION REPORT STRUCTURE NO. 5530-001T

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.
