PART 1 GENERAL
1.01 SCOPE OF WORK
A. The asbestos abatement and disturbance work related to this Project will consist of the removal
and disposal of asbestos containing materials (ACM) and presumed asbestos containing
materials (PACM) throughout at Tigard High School as a part of a planned bond renovation
project. This section is intended to provide instruction for requirements in connection with
asbestos abatement or disturbance to materials containing asbestos and is complementary to
the other contract documents, which apply to this section by reference.
B. For Work described in this Section, the Abatement Contractor (Contractor) shall furnish all
labor, materials, equipment, tools, and any other resources necessary to complete the work in
accordance with regulatory requirements and project'contract documents, using best available
technology and industry standard methods and procedures. The work shall include but not be
limited to the removal and/or disturbance work of ACM and PACM as described below:
I1. 42,850 Square Feet of Floor Tile and Mastic (9" and 12")-- Various 9" x 9" and 12"
x 12" Floor tiles have been found to contain up to three percent(5%) chrysotile asbestos
with up to five percent (3%) in the associated mastics. The asbestos containing floor
tiles and associated mastics were identified in various locations throughout the work
area. Any additional flooring materials identified, that have not been tested and may be
impacted by the renovation must either be presumed to contain asbestos or be sampled
to determine if the flooring materials are negative for asbestos.
2. 400 Each Hard Fitting TSI Elbow Insulation — Hard pipe fitting insulation located
throughout the tunnel system and within ceiling and wall cavities of the work area.
Fittings are associated with non-asbestos containing pipe run insulation. Contractor
should provide a line item per fitting price for any additional fittings needing abatement
above and beyond the 400 that are estimated.
1 3, 500 Square Feet of Sheet Vinyl Flooring — Vinyl Sheet flooring located within the
auxiliary gym training room.
4. 11,950 Linear Feet of Caulking — Window and door caulking located throughout the
work areas. Much of the caulking is located in the northwest area of the building however
based on not having the ability to differentiate between various caulking's that were
found to contain asbestos and the ones that don't, all of the various caulking's were
assumed to be asbestos containing. Any caulking that may be impacted by the
renovation must either be presumed to contain asbestos or be sampled to determine if
the material is negative for asbestos.
5. 24,000 Square Feet of Built-up Roofing — Roofing located above the C57/C56
Classrooms as well as above the auxiliary gym were identified to contain asbestos.
6. 550 Square Feet of Boiler Insulation — Boiler insulation located within the boiler room
was found to contain asbestos. The boiler insulation is labeled as asbestos free but was
sampled during the most recent survey and found to contain asbestos.
' 7. 40 Fire Rated Doors and Frames — All the fire rated doors and frames have been
presumed to contain asbestos. The fire doors are located at entrances to the hallway,
1
Tigard High School— Bond Renovation December 8, 2017 111
Asbestos Abatement Contractor Bid Document and Specification TRC Job#281719
locker rooms, and possibly to office areas. All fire rated doors and frames that may be
impacted by the renovation must either be presumed tocontain asbestos or be sampled
to determine if the material is negative for asbestos prior to disposal. 1
8. 220 Square Feet of Mirror Mastic—All of the mirrors contain mastic which is presumed
to contain asbestos. The mirrors are located in the locker rooms and offices. All mirrors
that may be impacted by the renovation must either be presumed to contain asbestos
and abated or be sampled to determine if the material is negative for asbestos prior to
being impacted by the renovation activities.
Please refer to Appendix A for more detailed information concerning asbestos surveys for
the site. Estimated quantities are provided as an approximateguide to the Contractor. The
material quantities listed in the list above are approximations and TRC is not responsible for
the accuracy of the quantities and measurements provided. The Contractor shall field verify
all material quantities, locations, and make themselves cognizant of existing field conditions
prior to submitting bids for the work of this specification. Submitting of bids for work described
herein shall take into consideration and utilize the Contractor's field measurements of
materials and observations of the conditions verified on site.
C. The Contractor shall be aware of all conditions of the Project and is responsible for verifying

quantities and locations of all Work to be performed. Failure to do so shall not relieve the
Contractor of its obligation to furnish all labor, equipment, and materials necessary to perform
the Work.
D. All Work shall be performed in strict accordance with the Project Documents and all governing
codes, rules, and regulations. Where conflicts occur between the Project Documents and
applicable codes, rules, and regulations, the more stringent requirement shall apply.
E. Working hours shall be as required and approved by the Owner. Asbestos abatement activities
including, but not limited to,work area preparation, gross removal activities, cleaning activities,
