EXECUTIVE SUMMARY

A routine inspection was performed at structure number 13599 on 26 February 2019 in accordance with the Code of Federal Regulations, Title 23, Part 650, Subpart C -

National Bridge Inspection Standards (NBIS) and the requirements for routine inspection as specified in Army Regulation (AR) 420-1 “Army Facility Management”, Chapter 7 “Transportation Infrastructure and Dams.” The previous NBIS inspection was performed on 28 July 2017. Subsequent routine NBIS safety inspections should be performed at regular intervals not to exceed twenty-four months in accordance with the

NBIS.

Bridge 13599 is in poor condition overall (NBI Rating = 4). This condition has not changed significantly since the previous inspection. Following is a list of the most significant findings.

• No load rating document of the structure.

• Deficient traffic safety features.

• Shear and flexure cracking and exposed rebar on T-beams.

• Spall with exposed rebar in the deck underside.

• Scour around abutments (degradation and aggradation).

• Large scour hole with undermining in channel upstream from the structure.

• Erosion and undercutting of the downstream channel banks.

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

None of the deficiencies at this bridge are considered critical, so no immediate corrective actions are needed. Current repair/maintenance recommendations include the following (described in more detail in Table 1 & 2):

Perform and document a load rating.

Upgrade traffic safety features to state requirements.

Monitor crack growth in concrete T-beams.

Clean and patch exposed rebar areas.

Install countermeasures to address scour and erosion.

The bridge is currently not posted for weight restrictions. The bridge requires a load rating to be performed and documented, and civilian posting signs installed if necessary.

SUMMARY OF FINDINGS

Critical Findings / Sustainment Deficiencies and Recommendations:

Table 1 shows all critical findings that require immediate attention. Table 2 shows the deficiencies and recommendations for the bridge that should be completed over the next two years, or for larger rehabilitation or replacement projects where planning and design should begin. The estimated costs in Tables 1 and 2 are approximate costs based on the cost of material and labor required to complete the recommended repair, in U.S. dollars. All cost data is based on current bid tabulations from contract cost data reported by the California Department of Transportation. These approximate cost estimates should only be used as a reference and for project planning purposes. Although they represent the costs for individual repair activities, they may not represent the total cost of a complete repair/rehabilitation project. Costs such as

Engineers’ Office, Submittal Reviews, Mobilization and Demobilization, Maintenance of

Traffic, Stream Diversion, Contractor's bond etc. would have to be added to the costs provided to develop a complete project cost.

ITEM # 113: SCOUR CRITICAL BRIDGES

N Bridge not over waterway.

U

Bridge with "unknown" foundation that has not been evaluated for scour. Until risk can be determined, a plan of action should be developed and implemented to reduce the risk to users from a bridge failure during and immediately after a flood event. (see HEC 23).

T

Bridge over "tidal" waters that have not been evaluated for scour, but considered low risk. Bridge will be monitored with regular inspection cycle and with appropriate underwater inspections until an evaluation is performed. ("Unknown" foundations in "tidal" waters should be coded U.)

9 Bridge foundations (including piles) on dry land well above flood water elevations.

Bridge foundations determined to be stable for the assessed or calculated scour condition: Scour is determined to be above top of footing (Example A) by assessment (i.e., bridge foundations are on rock formations that have been determined to resist scour within the service life of the bridge4), by calculation or by installation of properly designed countermeasures (see HEC 23).

8P Bridge is a culvert-type structure with paved bottom.

8L Bridge has been evaluated / assessed as a low risk structure and no further study is required.

Countermeasures have been installed to mitigate an existing problem with scour and to reduce the risk of bridge failure during a flood event. Instructions contained in a plan of action have been implemented to reduce the risk to users from a bridge failure during or immediately after a flood event.

Scour calculation/evaluation has not been made. (Use only to describe case where bridge has not yet been evaluated for scour potential.)

6R Bridge is scheduled for major rehabilitation or replacement within the next 5 years; the scour study is deferred to the location/design phase of the bridge project. Periodic monitoring may be necessary.

6U

Bridge foundations are unknown. The bridge site conditions have been evaluated / assessed with cursory study in the field and office, and the risk of potential damage from scour is judged to be moderate or mild.

Structure has no history of scour problems. Further evaluation is deferred. If the risk of damage from potential or actual scour damage is judged to be severe, additional scour studies will be undertaken including borings or others means of subsurface exploration to ascertain foundation and supporting soil conditions.

Bridge foundations determined to be stable for assessed or calculated scour condition: Scour is determined to be within the limits of footing or piles (Example B) by assessment (i.e., bridge foundations are on rock formations that have been determined to resist scour within the service life of the bridge), by calculations or by installation of properly designed countermeasures (see HEC 23).

RBI-HUA-19-13599-40

Bridge foundations determined to be stable for assessed or calculated scour conditions; field review indicates action is required to protect exposed foundations (see HEC 23).

Bridge is scour critical; bridge foundations determined to be unstable for assessed or calculated scour conditions:

- Scour within limits of footing or piles.

- Scour below spread-footing base or pile tips.

3M

Bridge is rated as scour critical on the basis of an evaluation and/or analysis; the potential risk is judged to be mild or moderate, and no actions are planned other than monitoring during routine inspections and after flood events.

3C

Bridge is rated as scour critical on the basis of an evaluation and/or analysis; the potential risk is judged to be severe and scour countermeasures are planned. Monitoring is to be performed until scour countermeasures are in place.

Bridge is scour critical; field review indicates that extensive scour has occurred at bridge foundations, which are determined to be unstable by:

- a comparison of calculated scour and observed scour during the bridge inspection, or

- an engineering evaluation of the observed scour condition reported by the bridge inspector in Item 60.

Bridge is scour critical; field review indicates that failure of piers/abutments is imminent. Bridge is closed to traffic. Failure is imminent based on:

- a comparison of calculated and observed scour during the bridge inspection, or

- an engineering evaluation of the observed scour condition reported by the bridge inspector in Item 60.

0 Bridge is scour critical. Bridge has failed and is closed to traffic.
