STRUCTURE EVALUATION SUMMARY

This concrete tee-beam bridge has some problem areas that are pressing and need to be addressed. Several areas of concrete spalling are present, primarily in the deck underside, beams, and substructure, and several previously repaired (in 2011) areas are deteriorating as well.

The delamination and spalling of the bearing areas at the pier caps appears to be progressing, as evidenced by a new spall on the south side of the west end of the Pier #14 cap. The spall has resulted in a loss of bearing for the full width of the steel bearing plate by up to 1/2" wide. The bridge plans indicate the bearing plate as actually the top flange of an embedded tee section, which provides significant capacity for the bearing for the time being. Regardless, to help ensure safe use of the bridge, this and other delaminated and spalled bearing areas should be addressed with a more comprehensive and effective repair project in the near future.

This structure is scheduled for rehabilitation under Project No. COLO 1B37, 1D46. The scope of this project includes repair of all deteriorated concrete on the piers, deck underside, abutments, beams and diaphragms, install scupper extensions, and reseal the deck expansion joints.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 4290-022P

A (Critical) - Structure is closed, in imminent danger of collapse, or presents a critical safety hazard.

B (Major) - Structure exhibits severe deterioration, presents a safety hazard, or is designated a high priority due to age and/or condition.

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.

FIELD INSPECTION REPORT STRUCTURE NO. 4290-022P

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.
