1.0 INTRODUCTION
The intent of this report is to identify the locations and content of
accessible friable and non -friable asbestos containing building materials
(ACBM), co assess the condition of the friable ACBM, to access its hazard
potential and provide removal cost estimates for the ACBM at the Building
"B", 19620 Stevens Creek Boulevard, Cupertino.
This survey addresses accessible friable and non -friable suspect materials.
triable materials include materials chat can be crumbled, pulverized, or
reduced to powder, when dry, by hand pressure. Non -friable materials can
become friable by being rendered to a crumbled, pulverized, or powdered
stace, when dry, by crushing, sanding, sawing or shot-blasting, severe
weathering or other mechanically induced means.
Or. September 3, 1993, Larry Everton, an Environmental Protection Agency (EPA)
Certified Building Inspector/Management Planner from ACC Environmental
Consultants, Inc. (ACC), performed a survey of Building "B".
The suspect macerials identified and sampled consisted of:
Surfacing Materials
none
Thermal Systems Insulation
none
Miscellaneous Materials
roof tar
roofing felt
transite shingles
joint mudding compound
floor the and adhesive
glue -or. ceiling tile
sheet vinyl flooring
2.0 EXECUTIVE SUMMARY
.Nofriable asbestos containing materials were found in this building.
The non -friable ACBM found at Building "B" includes roof tar, transite shingles,
roofing felt, and 9" x 9" white floor tile and adhesive. Actual descripcicrs,
locations, and quantities o: these materials.are detailed in Section 3.2 of chis
report. A summary of estimated removal costs is listed in Section 6.0. ACC
does not recommend removal of any of these materials unless demolition or
renovation activities,will disturb them.
Page 1
As long as asbestos containing materials remain at this building, an operations
'and Maintenance (O,&M) Program should be instituted to alert maintenance,
custodial workers and outside vendors of the existence and location of these
materials and to set policy for the maintenance of these materials.
This report is based upon conditions and practices observed and information
made available to ACC Environmental Consultants, Inc. This report does not
purport to identify all hazards or unsafe practices nor to indicate that
ocher hazards or unsafe practices do not exist. No responsibility is
assumed for the control or correction of conditions or practices existing
at the premises.

3.0 TYPE, LCCATION AND QUANTITY OF ASBESTOS CONTAINING BUILDING MATERIALS
This survey addresses friable and non -friable suspect materials.. Examples
of friable materials include, but are not limited to, spray applied
fireproofing on structural steel members, spray applied acoustical ceiling
macerial, acoustical ceiling tile and thermal systems insulation. Examples
of non -friable materials include, but are not limited to, roofing material,
floor tile, linoleum and adhesives used to glue them in place, fabric,
caulking compounds, wall and ceiling plaster, exterior stucco, wallboard
board joint compound and cement "transite" products.
ACC shall not be responsible for identifying asbestos -containing materials
located behind walls and/or columns, beneath flooring, under carpeting, above
solid ceilings, underground or any other inaccessible areas. Roof samples were
obtained during the inspection.

• 3.1 FRIABLE MATERIALS
No friable asbestos containing materials were found in Building "B".
3..2 NCN-FRIABLE MATERIALS
There is approximately 1000 square feet of asbestos containing roof car on the
roof in Building "B". This material, identified as sample R1, is reported to
contain 121 Chrysotile asbestos. ACC estimates the removal cost for this
material is $2,000. -
':here is approximately 1300 square feet of asbestos containing trans'ite si:c'-es
on the roof in Building "B". This material, identified as sample 13, is
retorted to contain 15V Chrysotile asbestos. ACC estimates the removal cost t.,_
this material is $5,200.
':here is approximately 320 square feet of asbestos containing roofing felt on
the parapet wall in Building "B". This material, identified as sample '14, is
_emcrted to contain 45: Ch^ sot' -le asbestos. ACC estimates the removal cost
this material is $640.
There is anoroximately 160 lineal feet of asbestos containing roofing felt or.
the top of the parapet wall in Building "9". This material, identified as
sample »5, is reported to contain 55V "Chrysotile asbestos. ACC estimates the
. removal cost for this material is $500.
':here is approximately 2000 square feet of asbestos containing joint mudding
compound throughout all areas on the first floor in Building "B". This
material, identified as sample #7, is reported to contain 2t Chrvsoti'_e
asbestos. ACC estimates the removal cost for this material is $6,000.
:'here is approximately 850 square feet of asbestos containing 9" x 9" white
floor tile and adhesive throughout room 1230 on the first floor in Buil-ding "B"
This materia'_, identified as samples #8 and #9, is reported to contain 2:
Chrysotile asbestos in the tile and!SVChrysotile asbestos in the adhesive.
ACC estimates the removal cost for this material is $1,700.
4.0 GENERAL BUILDING CONSTRUCTION AND SYSTEMS DESCRIPTION
Building IIBII located at 19260 Stevens creek Boulevard in Cupertino is part of a
three building complex owned by the wells Fargo Bank Corporation. it is di•:_ded
into 3 or 4 commercial office spaces under one roof.
The building exterior consists of painted stucco and glazing. The f'loor'ing is
wood framed and finished with floor tile, sheet vinyl and carpet over pi_rwccd.
The'rcof is a wood framed system that supports a manzard facade around the
building perimeter with a flat section in the center supporting HVAC Ecr4`pment.
This flat section is built up rolled roofing over plywood.
The interior partitions are wood framed and finished with painted gypsum
wallboard and ceramic tile in the restrooms. The ceiling is wood framed and
finished with 12" x 12" glue -on ceiling tiles and painted gypsum wallboard i
the restrooms..

Heating, ventilation and air is supplied from forced air heating and chiller
units located on the roof and connected to each space by ducting throughout the
attic space. Hot water is provided by copper lines from the.water heating tank
in .the mechanical room.
5.0 OPERATIONS AND MAINTENANCE PROGRAM
The lack of a known, safe level of asbestos exposure is the reason for
implementation of an Operations and Maintenance Program. Research and physical
.,evidence have proven conclusively that 'asbestos damages the human lunc tissue.
Asbestos related lung diseases are debilitating and almost always fatal.
Studies over the past 30 years have documented thousands of such ases among
insulation workers, and even persons indirectly exposed to asbestos fibers. The
question of how much asbestos can be inhaled without causing damage to the lures
in unclear.
The purpose of an 0&M program is to minimize building user exposure to airborne'
asbestos fibers. The 0&M program is designed to train maintenance and custodial
workers in the proper procedures to be used when working in and around asbestos
containing building materials and to continually monitor the condition of these
materials.
The first step of an O&M is to alert those workers who may come in contact with
the ACHM as part of their maintenance or routine duties that the material
contains asbestos. Only wher. the location of the material is known, can the O&M
program work effectively to prevent disturbance of the material which in turn
prevents fiber release.
Whenever ACHM is found to be damaged, the O&M training provides the techniques
and use of specialized equipment safely and properly repair the damage as well
as decontamination of the surrounding vicinity where asbestos fibers may be
present. The O&M training must include the proper use and fit testing of each
person who wears a respirator.
Asbestos management is a dynamic process. Since there are no guarantees that
the condition'of the asbestos will go unchanged over time, that workers will not
disturb. the materials, or that outside vendors or other service personnel will
always know the proper safety precautions, ACC recommends an O&M program as long
as friable or potentially friable asbestos remains in these buildings.

6.0 REMOVAL COST ESTIMATES
The following cost estimates for the ACBM identified at Building "B" are
based on prices recently obtained from projects at locations with similar
materials. Prices may vary markedly from those listed depending on
industry conditions, contractor work loads, removal control methods and
other factors. Lower prices may be obtained by combining one or more of
the materials in a single project. Prices do not include demolition,
replacement, reconstruction, project design, management or sample analysis
costs.
