STRUCTURE EVALUATION SUMMARY

This steel multi-beam bridge is in fair condition overall, and has only minor problems at this time. These include rusting of the bridge railings; leakage through the deck joints over the piers; accumulation of debris on the deck surface; erosion of the approach roadway embankment; spalling and cracking with efflorescence and rust staining on substructure elements; and a lack of object markers at the bridge corners. Corrective measures should be taken as outlined in this report to prevent the possible development of more serious or costly problems in the future.

The condition of the paint system and steel elements will continue to be monitored during subsequent inspections, and repainting may be recommended in the future.

There have been no significant changes since the previous inspection.

CONDITION ASSESSMENT:

ED MILTNER, P.E., FIELD TEAM LEADER

REPORT REVIEW:

MARCUS MILLER, P.E., BRIDGE INSPECTION ENGINEER 703-404-6252

REPORT APPROVAL: DATE: 12/9/19

JORGOMAI CEESAY, PH.D., P.E., BIP SUPERVISORY ENGINEER 703-404-6244

FIELD INSPECTION REPORT STRUCTURE NO. 9830-007P

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 sec ion 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.
