Structural Engineer

s e a u
SEAU

Structural Engineers Association of UtahEstablished in 1980, membership of approximately 250 engineers

Promote public awareness of structural engineering

Committee structure to support technical and practical aspects of the profession.

Structural Engineers Emergency Response committee (SEER) formed in 2002.

SEAUSEER

Utah’s SEER

modeled after NCSEA program

Established after Sept. 11, 2001

when City of New York asked

SEAoNY to organize teams to

provide assistance with disaster

Other programs:

California Post-Disaster Safety Assessment Program (SAP)Applied Technology Council ATC-20 “Procedures for Post-Earthquake Safety Evaluation of Buildings”

s e a u s e e r4
SEAUSEER

How Does it Work?Local Jurisdiction requests assistanceSEAU SEER committee helps organize “teams” including building officials, structural engineers and others prepared to evaluate damaged buildingsTeams visit affected buildings and “tag” structures based on safety requirements.Reports filed with authority having jurisdiction for follow-up.

ATC Placards

Green = Inspected

Yellow = Restricted Use

Red = Unsafe

SEAU SEER

Why Needed in Utah

  • Post-earthquake building evaluations are responsibility of local building departments
  • How well we were prepared for response to an emergency is ultimately judged after the event
  • More people, more buildings
  • Earthquakes can happen at any time. (No forewarning)
  • There is no test-of-time for buildings which have not experienced an earthquake

SEAUSEER

FEMA HAZUS Study

s e a u s e e r8
SEAUSEER

Do The Math

HAZUS estimates about 239,694 buildings will be at least moderately damaged.(This represents about 42% of the total number of buildings in the 9 county region)

It is estimated that a two person team can investigate approx. 10 bldgs./day

(10 bldgs./day / 2 persons/team = 5 bldgs./person/day

# buildings estimated to need inspection = 239,700

Response time# persons req’d# teams req’d

7 days 6,850 3,425

14 days 3,424 1,712

30 days 1,598 799

60 days 799 400
