COUNCIL AGENDA REPORT STEM NUMBER: -4f
FROM: Wayne A. Peterson, Acting Public Works Director
PREPARED BY: David Elliott, Administrative Analyst
SUBJECT: Seismic Safety Corrections for Fire Station No. 3
CAO RECOMMENDATIONS:
By motion:
1) Approve plans and specifications for "Seismic Safety
Corrections to the City of San Luis Obispo Fire Station No.
3 - City Plan No. S-35X"
2) Authorize staff to solicit bids on the construction contract
3) Authorize the CAO to award the construction contract if the
lowest responsible bid is within the engineer ' s estimate.
DISCUSSION:
An engineering survey conducted by H.J. Degenkolb Associates in
1990 found two possible structural deficiencies in Fire Station
No. 3 .
• inadequate lateral bracing across the front and rear of the
building caused by the large apparatus room door openings
and the need for unobstructed open area in the apparatus
room
• lack of positive anchorage between the wall framing and the
foundation walls.
The Degenkolb report concluded that the station might pose a
"low" risk to life safety in a major earthquake.
A thorough structural analysis by Howard F. Stup and Associates
in 1991 completed the following tasks:
• confirmed the findings of the Degenkolb report about
inadequate lateral bracing
• concluded that the lack of positive anchorage did not pose
a problem
• discovered a lack of positive connection between a small
flat roof and a wall at the southeast corner of the
building
• proposed a design for corrections based on standards for
Seismic Zone 4 of California Administrative Code Title 24
Construction plans prepared by Stup and Associates call for:
• installing steel columns at the ends of the two steel beams
which span the interior of the apparatus room
• welding the columns to the beams
• anchoring the columns to the concrete floor of the
apparatus room
. installing bent sheet metal clips to connect the flat roof
sheathing to blocking within the adjacent wall

COUNCIL AGENDA REPORT
Seismic Safety Corrections for Fire Station No.
Page 2
These corrections should reduce the life safety risk from "low"
to "minimum" and should ensure that firefighting equipment and
personnel can respond to emergencies after a major earthquake.
FISCAL IMPACT:
The Seismic Safety Corrections project is included in the Capital
Improvement Plan of the 1991/93 Financial Plan on pages E-10 and
E-23 . $379, 000 is designated for construction with $25, 000
allocated for Fire Station No. 3 . The engineer ' s cost estimate
is $20, 000 including contingencies .
At its meeting on June 30, 1992 , the Council decided that this
project should go forward despite impending financial
difficulties. This decision was based on the following criteria:
• The project improves public safety.
Design is completed.
• There is a policy commitment to correcting seismic safety
problems, particularly with essential services facilities.
• This project involves maintenance of existing facilities.
