Subject: RESPONSE TO CITY COUNCIL QUESTIONS REGARDING M&C C-13056
AUTHORIZATION TO PROCEED WITH REVISED CENTRAL LIBRARY 1986 CIP
PROJECT
INTRODUCTION
The City Council asked three questions in the discussion of M&C C-13056,
"Authorization to Proceed with Revised Central Library 1986 CIP Project." The
questions were:
(1) What is being proposed to mitigate the water infiltration problem?
(2) Explain the third recommendation of M&C C-13056, and
(3) What would be the cost to abandon the existing Central Library facility in
favor of a new facility?
Included below are responses to those questions.
ell, WATER INFILTRATION PROBLEM
Several factors may have played a role in the problem of water infiltration at the
Central Library. The proposed plan to mitigate water infiltration into the Central
Library includes all of the following:
a) removal of the existing roofing and plaza paving,
b) closing and removal of Lamar Street,
c) removing the existing waterproofing system, and
d) installing a new waterproofing system.
This includes replacement of the expansion joint system that has caused so much
trouble in the lower level. The closure of Lamar will eliminte vehicular traffic which
we believe is a major cause of building movement. Building movement creates
hairline cracks through which water can enter the building.
After the waterproofing system is installed, a new plaza surface will be built that
is designed to shed the water from the building as quickly as possible to minimize
the possibility of future problems. During the reconstruction of the streets around
the library, a new storm drainage system will be installed to take the water away
from the library site. The new plaza material is also deisgned to inhibit the transfer
of stresses into the library structure that Could cause cracking.

AUTHORIZATION TO PROCEED WITH REVISED CENTRAL LIBRARY 1986 CIP
PROJECT
During the Phase One construction, it is proposed to Include much of the
underground structural portions necessary for future completion of the library
tower. In this way, it will not be necessary to penetrate the waterproofing system
a second time.
ENVIRONMENTAL EVALUATION (M&C RECOMMENDATION NO.3)
The roof of the plaza entrance will be replaced, and the skylights reworked to
stop the water infiltration at that point. The water damage to the ceiling of this
entrance must be repaired; however, before any existing materials can be
distrubed, an environmental assessment must be performed. It is believed -there
may be asbestos containing material present in the ceiling area, and if so, it will
be necessary to abate the material before replacing the roof. The written report
will address priorities and recommend remedial actions as well as provide
specifications for necessary abatement work. Any abatement work must then
occur prior to construction. A contract to remove any asbestos that may exist
would be brought before the City Council for consideration.
ABANDON EXISTING FACILITY
One suggested alternative is to abandon the existing Central Library facility in
favor of an entirely new building.
To replace the existing 125,000 square feet plus add the subsequent planned
square footage in the current design (a total of 197,000 square feet) would cost
approximately $30 - 38 million in today's dollars. To build the total completed
Central Library through Phase 3 (a total of 260,000 square feet) would require a
total expenditure of $40 - 52 million. These figures are based on the average cost
per square foot of (14) fourteen central libraries now being built in the United
States (See attached chart). The range accounts for variables such as the

inclusion of fees, furniture and equipment or just construction alone. These figures
do not Include the parking garage nor the cost of relocating the existing Central
Library functions while construction is underway, assuming the use of the same site
or land purchase costs if another downtown site is acquired. The costs do include
the additional structure and heating/air conditioning requirements for a larger
above ground facility.
To salvage any future use of the present underground facility, the water Infiltration
must be resolved even if used as a parking garage.
Should you have any further questions or require additional infomration regarding
this project, please do not hesitate to call.
