1. INTRODUCTION

The main purpose of this inspection manual is to provide engineers in the Structural

Engineering Division (SED) with a rapid and effective methodology to evaluate bridges

during an emergency. However, depending on the extent of the damages and the

urgency for immediate inspection, it is likely that there may not be an adequate number

of experienced structural engineering personnel available to immediately survey every

structure. This manual is intended to promote and maintain uniformity in evaluation as

much as possible while assessing and rating bridges for damage on a timely manner.

In this manual, the necessary material is arranged according to two levels of inspection.

Level 1 inspection consists of a rapid visual evaluation of bridges in the affected areas to

identify obviously unsafe structures. This could also include providing emergency shoring

or other temporary repair solutions. Level 2 inspection consists of a more in-depth safety

evaluation of select number of damaged bridges, as well as to provide additional and

more permanent repair solutions. Depending on the condition of each bridge, inspection

teams may choose to reduce the speed limit of incoming vehicles as they approach the

bridge, to restrict access only to emergency vehicles, or to close the bridge entirely to

traffic. The inspection teams should also consider shoring or other strengthening and

long term monitoring measures as required.

2. ALERT RESPONSE PROCEDURES 2.1 Summary

(*) See Section 2.2 for SED’s chain of command in the absence of Division Engineer.

City Hall Operator activates Emergency Operation Center (EOC) -- (staffed by BOE, BOS, BSS, LADOT, LAPD, LAFD, etc.)

City Engineer directs emergency activation of BOE’s Bureau Operation Center (BOC) -- (if he determines that the extent of the emergency is sufficient to justify this.)

BOE’s BOC staff (includes SED DE) are notified to report to work ASAP

SED DE(*) activates SED Command Center (CC), and notifies SED engineers to report for their bridge evaluation duties

SED DE(*) decides on Full vs Partial Deployment (based on extent of emergency by reports from TV, Radio, EOC & BOE’s BOC). In case of Full Deployment, SED CC will seek help from Bureau of Contract Administration (BCA) emergency inspection teams, by sending request through BCA’s BOC.

SED Inspection Teams will take: a} Emergency Kits; b) copies of CFOS files for bridges to be inspected; c) cell phones; d)cameras & films, and will check out City cars, and will proceed on their trips to perform Level 1 Inspections on their designated bridges.

SED Inspection Teams will report the results of their Level I evaluations (Green, Yellow, or Red) back to SED CC, and receive further instructions before proceeding to their next site. Contact shall be made at least once every 3 hours. Further evaluation (i.e. Level II inspection) could be requested by SED CC, which may require assistance from BSS crew.

EMERGENCY STRIKES

SED CC reports the evaluation results back to BOE’s BOC, which will in turn report to EOC. All Level 1 inspections are expected to complete within 24 to 48 hours.

2.2 Chain of Command in SED Command Center during Emergencies In the absence of SED Division Engineer, the Division chain of command to lead SED’s

CC will be in effect in the following order:

Name Title 1) Farid Baher Assistant Division Engineer 2) Vigen Gharibian Structural Engineer 3) Shirish Mistry Structural Engineer 4) Edward Arrington Structural Engineer 5) David Li Structural Engineer 6) Peter Chiu Structural Engineer 7) Tony Lim Struct. Engineering Assoc. IV 8) Massoud Tayyar Struct. Engineering Assoc. III

2.3 Details of Response Procedure

In the event of a regional emergency, the City Hall Operator will notify the Bureau of

Engineering and other designated Bureaus that the Emergency Operation Center (EOC)

has been activated. If it is determined by the City Engineer that the extent of the

emergency is sufficient to require emergency activation of the Bureau Operation Center

(BOC), the essential staff for the operation of the BOC will be notified to report to work as

soon as possible. SED Division Engineer, one of the lead personnel to be notified in

these situations, will then activate the SED Command Center and notify the SED

engineers to report for bridge evaluation duty. (For a detailed guide on the operation of

the EOC and BOC, please see the Bureau of Engineering's "Emergency Operations

Plan", available on the BOE's Intranet, where it is listed under "Distributed Info".)

After activating the SED Command Center, the SED Division Engineer (SED_DE) will

assess the extent of the damages and will make the determination whether to engage

into either a Partial Deployment or a Full Deployment.

- In a Partial Deployment, only a limited number of SED engineers would be

assigned to the evaluation teams.

- In a Full Deployment, SED_DE will mobilize all available SED (and trained non-

SED) engineers, and will request the Bureau of Contract Administration (BCA)

through their BOC to put all their available emergency inspection teams on an

Vgharibi

alert mode, so that they can be deployed as part of our inspection teams with

SED engineers to any given assignment in a moments notice.

The following flow-chart illustrates the interaction of EOC, BOE and BOC in times of

emergency.

The SED_DE, based on reports coming from City's Emergency Alert System (EAS),

radio or TV, as well as inspection requests from BOC and EOC, will determine the extent

and vicinity of damages, and will dispatch the first round of inspection teams to those

locations. Using the "Computer File Of Structures" (CFOS) reports sorted by Thomas

Guide page and grid numbers, a target list of bridges will be generated which will include

all the bridges located within the vicinity of the disaster. In a short period of time (say

within 24 to 48 hours), designated bridge inspection teams will perform Level I

inspections and validate the condition of ALL bridges within a 10-mile radius of the

"epicenter" of the disaster, or as otherwise designated by SED_DE.

With the condition of reports coming from each inspection team, the SED_DE and

his assistants will transfer the incoming data to a large-scale City wall map in the

SED Command Center, using red, yellow and green markers to indicate condition

of each bridge per conventions described later in Section 4.2 of this Manual. For

bridges which receive a red or yellow designation, SED_DE may send a Level II

inspection team to make further recommendations for the necessary temporary

fixes and repairs, or to close the bridge to public use if damages are extensive. The

completed Detailed Bridge Inspection Reports shall be turned over to SED Bridge

Inspection Section (BIS), for updating data in CFOS.

3. SED'S COMMAND CENTER

Following a disaster, and depending on the location of the disaster and physical

condition of SED's main office, SED_DE may consider to set-up its Command Center in

another BOE Office. For this purpose, the Valley District Office in Van Nuys and the

Environmental Engineering Division in West Los Angeles have been supplied with the

essential equipment and tools specifically designated to accommodate the inspection

needs of the SED evaluation teams when disaster occurs.

Depending on the time when the disaster occurs, SED’s Command Center can be

activated under one of the following two general scenarios:

Scenario I: Disaster Occurs During Working Hours SED_DE will initiate the deployment of the emergency inspection staff. Each

employee, of course, will first need to check the well-being of his/her own family,

by calling home, or children's school, or spouse's workplace. After verifying that all

employees' families are safe and sound, SED_DE will send them off to their

assigned field evaluation duties.

Scenario II: Disaster Occurs During Off-Working Hours or Off-Working Days

In the event a substantial disaster occurs during off-working hours, the SED_DE

and his Assistant Division Engineers shall discuss on the phone the extent of the

Citywide damages, the usability of the Downtown Office, and to decide whether

an alternate Command Center is needed. After deciding on a suitable location for

the Command Center, all pre-designated engineers will be notified by telephone

through SED's chain of command, to report to the designated SED's Command

Center. (See Appendix ‘A’).

4. TYPES OF BRIDGE DAMAGE

4.1 General

Vehicular bridges in general have a structural combination of superstructure, substructure and

support bearings. The superstructure consists of all the structural elements of the bridge like

slabs, beams, girders, arches, or truss members that make the horizontal spans. Substructures

consist of structural elements of the bridge that provide the support to the horizontal spans like

abutments, piers, columns and footings. Bearings are placed between the superstructure and

substructure. Figure 4.1 shows the key components of a typical vehicular bridge.

4.2 Bridge Damage Classification Based on the results of the inspection, each bridge can be classified as follows:

Green Condition => very little or no damage: Safe for Traffic – shall remain open to traffic

Yellow Condition => minor structural damage: Safe for limited traffic - may choose

to reduce the speed limit of incoming vehicles as they approach the bridge, may

restrict access only to emergency vehicles, may close specific lanes to traffic, etc.

Red Condition => major structural damage: Unsafe for Traffic – shall be closed to

traffic

More detailed damage classification tables are given in the Figure 4.2 by considering the different

components of vehicular bridges.

4.3 Examples of Bridge Damage In this section examples of different types of bridge damage are given. The damage examples follow the damage classification tables in the previous section. These examples are organized in the categories of:

Bridge Collapse / Partial Collapse Superstructure Damage Substructure Damage Bearing Damage Geotechnical Problems

Note: The photographs shown in these pages depict some "extreme" cases of damage that actually have occurred to some California bridges during past earthquakes. These pictures serve as dramatized illustration of some of the damages that may occur to a typical bridge. Actual damages, however, may not be as pronounced and discernable as shown here. Each bridge inspector should always bear this fact in mind, and shall look for those "not so obvious" damages during his/her inspections. Bridge Collapse

5. EMERGENCY EVALUATION PROCEDURES

5.1 Required Inspection Equipment

Each inspection team needs to take the following items, as minimum, before embarking to

the field for inspection (see Appendix ‘B’ for quantity of each item assigned to each team):

Inspection manual Thomas Guide List of bridges to be inspected A copy of the latest regular inspection CFOS report for each bridge to be inspected Several blank "Detailed Bridge Inspection Report" forms Clipboard, pen/pencil Pocket tape, ruler Orange safety vest Hardhat with City emblem Flashlight City car (see Note below) City standard padlock key ("Master" Brand #1C80) for opening gates at channel

access roads Safety roadside flares First aid kit Binoculars Yellow warning tape Printed list of important phone number (See Appendix A and D)

In addition to the above, the following items may also be taken based on their availability:

City assigned cell phone (if available, see notes 2 and 3 below) Camera and film (or digital camera) Rubber boots and rain gear, if needed Two-way radios (Walkie-Talkies)

Notes:

1. Valley and EED offices have each 7 assigned division cars at their disposal. To check out cars in downtown, inspectors need to contact the following GSD Dispatch offices:

- Parking Structure for 1149 S Broadway Bldg. … Tel: (213) 741-0737 - City Hall East, P-1 Level ………... Tel: (213) 485-5494 or (213) 485-6706

2. For a current list of SED cell phones and digital cameras, refer to Appendix ‘E’. 3. BOE’s Administration Division may have additional cell phones available for SED’s

emergency use. Contact Winnie Harano at (213) 485-4969 for availability.

5.2 Level 1 Inspection The Level 1 Inspection will be activated immediately after a major disaster, and will consist

of rapid assessment of bridges to evaluate their integrity. It is critical that the inspections for

Level 1 get done in a timely manner, so that bridges with serious structural damage can be

17

taken out of service temporarily before they cause human casualties. The results of Level 1

inspections will be utilized to develop the inspection schedule for the Level 2 teams.

All Level 1 inspectors will be grouped into teams of two [i.e. (2 SED engineers), or (1 SED

engineer + 1 BCA inspector)], and will be sent out to inspect their respective assigned

bridges.

A suggested general procedure for the Level 1 inspection can be summarized as follows:

1. After collecting the necessary tools for inspection from SED's designated Command Center (CC) (for a list of items included in each prepackaged supply box, see Appendix B), begin the inspection of the assigned bridges. If your other team member has not arrived at the CC, arrange to meet him/her at a bridge site closest to the CC.

2. Upon arrival at the bridge site, call SED CC and record the arrival time. [Important Note: If

a member of the media is present at the site and approaches the engineer with any questions, the engineer should politely refrain from making any statement, and refer the reporter to the City’s Public Affairs Office, at (213) 978-0333.] The engineer should then make a quick assessment of the bridge by walking down the side access ramps or channel embankments, and evaluate the overall condition of the bridge from the side(s). Approach each bridge with caution and never walk immediately upon arrival directly under or over the bridge. At no time the two Level 1 inspectors should go under the bridge at the same time, because they have to backup each other and there is always the chance of aftershocks while they are under the bridge. Do not cross the bridge without first sighting down the curb/rail line and checking the underside for structural damage. Caution is to be exercised when inspecting in remote locations and/or during after-hours, specially when in heavy vegetative growth area adjacent to bridges, channels, washes, culverts, tunnels. These types of environment pose extra threat of safety due to possible presence of wild animals, snakes, or other unforeseen situations.

3. Check the traffic flow on the bridge. Although there may be traffic using the bridge, it

does not indicate the bridge is safe. Inspect all bridges assuming they may be damaged.

4. Prepare an inspection routine of different bridge components. Begin by inspecting

roadways and approaches and continue in the order listed in the inspection form. Also compare your findings with the latest inspection data from the CFOS printout. (For a list of abbreviations and legend used in CFOS reports, see Appendix ‘F’).

5. After completing the inspection form, discuss your observation with the other member of

the team. 6. By using the guidelines shown in Fig. 4.2, make the final evaluation of the condition, and

mark the appropriate section at the bottom of the Inspection Form, by checking of the GREEN, YELLOW, or RED condition boxes.

18

7. Additional recommendations and observations about the bridge can be written in the box provided at the bottom of the form, or on the back of the form if notes will not fit in the box.

8. If a bridge receives a YELLOW or RED condition designation, one of the team members

should contact SED CC immediately and provide detailed information about the condition of the bridge. The inspection team shall not leave any bridge site which has a YELLOW or RED designation until they receive specific instructions from the SED CC.

9. At the end of each bridge inspection, sign, date and record the departure time on the

form. If the bridge is not assigned a YELLOW or RED condition, head to the next assigned bridge site, and on the way, the team member who is not driving shall call SED CC and report about the bridge just inspected.

10. Every inspection team needs to call the SED's Command Center at least once every

3-hours, to report on the progress of his/her team and receive new assignments. The SED_DE or his designee will receive those reports and make new assignments as necessary.

11. After completion of inspection for each batch of assigned bridges, return the

inspection reports to the SED's CC.

5.3 Level 2 Inspection

The main goal of Level 2 inspection is to perform more detailed inspection on specific

bridges, as determined by SED CC, which have suffered considerable damages and

have been barricaded as a result of Level I inspection. The result of Level 2 inspections

would help SED engineers to decide on whether to continue closing the bridge, or to

open some or all of the lanes on the bridge while repairs on the bridge are being

performed.

The general procedures for Level 2 inspection and the Form to be used during inspection

are the same as those for Level 1 (see Sec. 5.2). A typical Level 2 inspection team would

normally consist of two SED engineers or one SED engineer and one BSS crew. After

completing the inspection, team members should be able to make a determination

whether in-house repairs can be made, or the work needs the services of a specialized

contractor. It is important to note that the condition of damaged structures may worsen

due to additional aftershocks, traffic, or simply gravity. When assessing the bridges, one

should assume that additional earthquakes and/or aftershocks would occur and consider

19

what effects they may have. Sometimes, it may be necessary to establish a monitoring

plan to detect any changes in the condition of the damaged structures.

During the inspection of various types of bridge components, care must be taken to

make the correct assessment. All the structural elements, supports, bearing elements

and soil conditions should be checked. It is important to note that some reinforced

concrete elements such as box girders, footings, and piles cannot be readily inspected.

If damage of these elements is suspected, assistance from BSS crew may be required to

gain access to inspect some hidden areas. For example, excavating the soil around the

footings for checking pile caps may give a better idea for the damage. For the box girder

type of elements, opening maintenance hole covers to enter into the cells may become

necessary. Consult with applicable codes for "confined space entry" before engaging in

this kind of inspection.

For the steel components, inspection of the damage is often not readily apparent such as

in the concrete elements. All assemblies, plates, anchor bolts, restrainers, connections,

hangers, welds, and other details should be carefully inspected. Sheared bolts, buckled

or bent members, cracked welds, shifted girders, and anything out of the ordinary should

be noted. For the composite elements, anchor bolts used to connect steel elements to

concrete (such as connection between steel columns and abutments or pier caps)

should also be checked.

In the event the SED determines that the work needs the services of a specialized

contractor, the Bureau of Contract Administration’s BOC will be notified and the

Inspector of Public Works will assign the appropriate Inspection teams who will monitor

the work directed by the Engineer. If the work is to be performed on a Time & Material

basis, the work shall be performed and inspected by the Bureau of Contract

Administration under the Board of Public Works’ Policy on Time & Material.
