F&R Project No. K68-019E

Dear Mr. Reigle:

Per your request, Froehling & Robertson, Inc. (F&R) collected 6 samples of suspect asbestos-containing

material (ACM) on August 19, 2008 from the Georgetown Neighborhood Library as a follow-up to the Limited

Hazardous Materials Survey Report dated July 11, 2008 prepared by F&R. These samples were collected due

to the identification of ACM in historic architectural drawings of the building. These materials were not

sampled as part of the original survey as they were inaccessible under the scope of the non-destructive

investigation.

Samples were analyzed by polarized light microscopy (PLM) by AMA Analytical Services, Inc. of Lanham, MD, a

National Voluntary Laboratory Accreditation Program (NVLAP) certified laboratory. The stop positive method

was used when analyzing these samples. Utilizing the stop positive method, when there is a positive result for

a certain material, additional samples of that material are not analyzed. Samples collected included threesamples each of fiberboard duct lining and radiator casing insulation.

The fiberboard duct lining collected from the 1st floor lobby was determined to contain 60% Chrysotile

asbestos through laboratory analysis. F&R observed approximately 450 square feet of this material in encased

duct vents throughout the 1st floor. The radiator casing insulation collected from the 1st floor front stairwell

lobby was determined to contain 50% Chrysotile asbestos through laboratory analysis. F&R observed

approximately 50 square feet of this material in the 1 st floor front stairwell lobby. Please find the laboratory

results, location diagrams and photographs of the identified ACM attached.

F&R recommends that all fiberboard duct lining and radiator casing insulation identified throughout the

Georgetown Neighborhood Library be assumed to be asbestos-containing until sampling proves otherwise. AllACM should be removed by a District of Columbia licensed asbestos abatement contractor prior to impact by

renovation or demolition activities.

F&R estimates that abatement of the asbestos-containing fiberboard duct lining will cost approximately $5.00

per square foot for a total of $2,250.00. Abatement of the asbestos-containing radiator casing insulation is

estimated to cost approximately $25.00 per square foot for a total of $1,250. The provided costs are just

estimates and should not be used for budgetary purposes. These estimates were made with the assumption

that all ACM will be abated under one mobilization. F&R provided an estimate in the previous Limited

Hazardous Materials Survey Report of $7,500 and $2,000 for abatement oversight and Transmission Electron

Microscopy air clearance respectively. The identification of the asbestos-containing fiberboard duct lining and

radiator casing insulation should not have a significant cost impact on these services

GENERAL LIMITATIONS

This report has been prepared for the exclusive use of Martinez & Johnson Architecture and/or their

agents. This service was performed in accordance with generally accepted environmental practices. No

other warranty, expressed or implied, is made. Our conclusions and recommendations are based, in part,

upon information provided to us by others and our site observations. We have not verified the

completeness or accuracy of the information provided by others, unless otherwise noted. Our observations

and recommendations are based upon conditions readily visible at the site at the time of our site visit, and

upon current industry standards. During F&Rs non-invasive inspection, accessible areas were visually

surveyed for the presence of suspected ACM. Inaccessible areas, such as behind solid walls or above solid

ceiling were not surveyed and therefore suspected ACM may be present. Areas inspected for the above-

referenced materials were limited to those designated by the client.

During this study, suspect material samples were analyzed for asbestos. As with any similar survey of thisnature, actual conditions exist only at the precise locations from which suspect samples were collected.

Certain inferences are based on the results of this sampling and related testing to form a professional

opinion of conditions in areas beyond those from which the samples were collected. No other warranty,

expressed or implied, is made.

Under this scope of services, F&R assumes no responsibility regarding response actions (e.g. O&M Plans,

Encapsulation, Abatement, Removal, Notifications, etc.) initiated as a result of these findings. F&R assumes

no liability for the duties and responsibilities of the Client with respect to compliance with these

regulations. Compliance with regulations and response actions are the sole responsibility of the Client and

should be conducted in accordance with local, state, and/or federal requirements and should be performed

by appropriately qualified and licensed-personnel, as warranted.

Froehling & Robertson, Inc. by virtue of providing the services described in this report, does not assume the

responsibility of the person(s) in charge of the site, or otherwise undertake responsibility for reporting to

any local, state, or federal public agencies any conditions at the site that may present a potential danger to

public health, safety, or the environment. The client agrees to notify the appropriate local, state, or federal

public agencies as required by law, or otherwise to disclose, in a timely manner, any information that may

be necessary to prevent any danger to public health, safety, or the environment. The contents of the report

should not be construed in any way as a recommendation to purchase, sell, or develop the project site.

The Consultants Construction Cost Estimate (CCCE) provided in this document has been prepared for the

exclusive use of our Client and their authorized agents for use on this specific project. The purpose of this

CCCE is to provide a construction cost estimate for preliminary budgeting purposes only. It has been

prepared based on our experience within the environmental industry with projects of a similar scope of

services. No other warranty, expressed or implied, is made. Furthermore, it is not intended to replace

competitive bidding by construction contractors who are interested and qualified to perform the actual

services discussed in our survey report. The client recognizes that construction costs will also vary

dependent upon when the cost estimate is obtained verses when the work will be performed, in addition

to other such factors such as seasonality of the work in addition to the status of the economy. Therefore,

F&R does not assume liability for the use of the CCCE included in this report for purposes other than which

it is intended, as stated above.
