 applicable, vaporproof condition.
The A/E shall prepare and submit a report detailing the results of
all sample cuts taken accompanied by the lab analyses for asbestos
content. The report shall include the number and locations of cuts
taken, descriptions or sketches of all types of roofing assemblies
encountered and sketches indicating the method(s) of repair to all
cuts taken. As a minimum, the descriptions or sketches shall
indicate the type of aggregate surfacing, type and number of plies,
type, thickness and number of layers of insulation, type of vapor
barrier, type of roof deck, type of flashing, and the location of any
asbestos material detected, as applicable. All visible detrimental
conditions, such as saturated insulation or damaged roof decking,
shall also be noted.
The A/E shall use the report to incorporate details, with dimensions,
on the drawings to illustrate the types and extent of roof assemblies
present as determined from the sample cuts. Such details shall be
clearly labeled as existing construction so as not to be confused
with the new work to be done.
The sampling and testing of roofing materials for asbestos content
shall conform to the appropriate requirements of the paragraph titled
"Asbestos Samples/Analysis, Removal and Disposal Report" in this
chapter. Samples for asbestos testing of the roof membrane shall be
removed from the roof core samples; separate samples need not be
taken.
(NOTE: SEE THE CHAPTER TITLED "STRUCTURAL DESIGN" FOR REQUIREMENTS
REGARDING ANALYSIS OF THE ADEQUACY OF EXISTING ROOF FRAMING TO
SUPPORT THE NEW ROOFING SYSTEM FOR REROOFING PROJECTS.)
15.7
Asbestos Samples/Analysis, Removal and Disposal Report
Various existing materials found in facilities undergoing
alteration/rehabilitation/addition or removal shall be suspected of
containing asbestos. The A/E shall make all reasonable efforts to
investigate, detect and evaluate such materials during the site
investigation phase of the project. Such efforts shall include
retrieval of samples from exposed areas, including those not normally
reached from floor levels and, in the case of removal work, sub-
surface investigations, and lab analysis as appropriate to assure
detection of all significant amounts of asbestos.
The A/E shall ensure that sampling of materials suspected of
containing asbestos is performed by or under the direction of an
American Board of Industrial Hygiene (ABIH) certified industrial
hygienist. The A/E provided laboratory that analyzes the collected
samples shall be a successful participant in the National Institute
of Standards and Technology National Voluntary Laboratory
Accreditation Program (NIST/NVLAP) sponsored quality assurance
program for asbestos identification and have demonstrated proficiency
in asbestos analysis. The A/E or company taking samples shall comply
with all safety and environmental regulations during field
investigations and take precautions to protect human health and the
environment as required by federal, state and local regulations.
