• Geotechnical Evaluation
• Transportation Systems
• Airports
• Bridges
• Roads

• Water/Wastewater Systems
• Pipeline
• Pump Station

• Water Treatment Plant                 

3
General Procedures

• All lifeline evaluations are Detailed Evaluations
• Instead of tagging, the responsible authority is
  informed of results
• If a facility is found to be unsafe, the
  authority is contacted immediately, so proper
  steps can be taken.

4
Assessment Form Heading

• See pages 134 136 in student manual.
• All the lifeline forms use the same heading.
• Facility name, address
• Date time, type of disaster
• SAP ID numbers
• Estimated damage
• Facility status (red, yellow, green)
• Section A Condition existing posting,
  recommended posting

5
Geotechnical Evaluation

• Only non-lifeline specific assessment
• Applies to all evaluations
• Can be requested for any evaluation
• Begin evaluation at point in question then spread
  out.

6
Geotechnical Evaluations

• Liquefaction
• Lateral Spreading
• Expansive Soils
• Landslides
• Differential Settlement

• Major bridges on the highways and freeways will
  be evaluated by CA Dept. of Transportation
  (Caltrans).
• Used to evaluate bridges not a part of the
  national highway system and located within the
  jurisdiction.

26
Bridge Evaluations

• Types of Damage
• Support columns fail in shear.

  determine what streets are useable.
• Will most likely be used to re-evaluate as
  streets are needed.

36

Pipeline Evaluations

• Used to evaluate water and sewage lines.
• How pipelines are evaluated will be up to the
  jurisdiction.
• Usually assigned a segment of the system be
  prepared to evaluate other facilities that are a
  part of the system such as pump stations and
  reservoirs

43
Pipeline Evaluations

• Types of damage
• Joint damage or separation.
• Bursting.
• For water systems entire areas of the system may
  lose pressure and can result in water boiling out
  of the ground.

44
Pipeline Evaluations

• Types of damage (Continued)
• Sewer pipelines may collapses, causing backup and
  possible overflow.
• In liquefiable soils, sewers and manholes will
  float, making them hydraulically inoperable.
• Identification of these types of failures will
  only be possible using specialized equipment.

Pump Station Evaluations

• Pump stations are found with water, wastewater,
  natural gas (compressor stations), and liquid
  fuel pipelines.
• All but wastewater pump stations are usually at
  grade, and may have components as deep as 10 feet
  below grade.

52
Pump Station Evaluations

• Types of damage
• Loss of power.
• Damage to the emergency power system.
• Fallen electrical and control cabinets.
• Damage to piping.
• Wastewater pump stations are often founded in
  liquefiable soils such that they become buoyant,
  breaking connecting piping.

Reservoir (Tank) Evaluations

• Water tanks are highly susceptible to damage from
  earthquakes.
• The potential is there for evaluations following
  other types of events or situations, but it will
  be earthquakes where they are most often used.
• Important components of a jurisdictions
  infrastructure, especially when their main water
  supply has been disrupted.

59
Reservoir (Tank) Evaluations

• Types of damage (Steel Tanks)
• Uplift, breaking connecting piping.
• Tank wall wrinkling, commonly referred to as
  elephants foot buckling.
• Wall-floor seam can burst.
• Sloshing water can damage the roof, although this
  is not likely to result in loss of service.

60
Reservoir (Tanks) Evaluations

• Types of damage (Cable Wrapped Concrete Tanks)
• Failure of the wrapping as a result of corrosion
  of inadequate design.
• Older tanks can slide off their floor slab
  foundations
• Roofs are also vulnerable.

Wastewater Treatment Plant

• Complex systems made up of many components and
  systems
• Buried and above grade pipe,
• Cast-in-placed concrete basins and galleries,
• Buildings, and
• Chemical, gas, piping, and electrical systems.

70
Wastewater Treatment Plant

• Types of damage
• Expansion joints have failed, allowing sewage to
  drain into galleries and
• Baffles in large basins have broken as a result
  of sloshing sewage.

71
Wastewater Treatment Plant

• The goal is to keep as much of the plant in
  operation as possible.
• It is desirable as a minimum to maintain
  operation of the headworks, primary sedimentation
  basins, and chlorine disinfection system, even if
  the secondary or tertiary systems were heavily
  damaged and not operational.

• Posting
• If determined the wastewater treatment plant

• They will notify Public Works who will notify the
  plant operators.
• If you have performed building evaluations, make
  sure to post the buildings.

76
Water Treatment Plant

• Types of damage
• Similar to wastewater treatment plants
• Damage to baffles due to sloshing water inside
  basins is common.
