CLARIFICATIONS: 1) Per the mandatory job walk there will be a concurrent electrical infrastructure project occurring between the dates of 12/22/12 through 01/01/13, contractor to provide all temporary electrical generators and lighting as required. 2) PSU has confirmed that all non-louvered panels of the existing cooling tower contain transite asbestos. Contractor to provide demolition and disposal of asbestos per all state, local and federal codes, see the attached PSU specifications.

2 3) Contractor to provide a logistics plan as a part of the submittal package. The adjacent green space can be used as a staging area but it must be re-planted, as required, to match existing condition. The adjacent driveway can be used for a crane pick area and material drop off point but specific times for use of that driveway must be coordinated with PSU staff. 4) Provide 3-D engineered drawings of the project piping; only new piping is required to be shown up to the tie in points. This will be required in the submittal package and included in the as-built documentation. 5) Contractor is to provide a chemical treatment plan as a part of the submittal process. 6) Per the job walk, the cooling tower VFD is to be ABB or approved equal and provided with the cooling tower and to be located within the cooling tower control panel. Substitution Requests: BAC Cooling Tower This substitution request has been rejected for the following reasons: 1. BAC unit has a higher pressure drop 7.85 psi vs. 2.4 psi 2. Not clear what materials are being submitted; EVAPCO is stainless on lower half including the basin. 3. Options of ladder/platform, vibration switch, flume plate, control panels, VFD, louver access panel, seismic construction are not included 4. Dimensional constraints of this existing cooling tower yard limit the width that can be used; BAC is 21-6 wide vs Top connection for condenser water is a problem for hiding the piping. Project has strict visual campus/ city of Portland constraints. 6. Documentation provided did not adhere to Division section 3.01 of the project specification. Puroflex Sump Sweeper This substitution request has been rejected for the following reasons: 1. The model submitted does not match the pressure requirements of the basis of design product. 2. Documentation provided did not adhere to Division section 3.01 of the project specification.

7 PORTLA STATE UNIVERSITY ASBESTOS SURVEY SCIENCE BUILDING SW 10 TH AVE., PORTLA, OR REVISED JULY 21, 2008 FORENSIC ANALYTICAL PROJECT #PJ4385 PAGE INTRODUCTION Forensic Analytical Specialties, Inc. performed an inspection to identify asbestos-containing building materials at the property located at 1719 SW 10 th Avenue, Portland, Oregon. Noal Kraft, Dan Rouse, and Robin Sharpe conducted the field investigation on April 1 through April 3, 2008, at the direction of Kate Vance, of Portland State University Facilities and Planning. The purpose of the inspection is to determine whether ACM is present in the structures onsite. The subject property consists of a four story building with three basement levels equaling approximately 215,860 square feet. The building was constructed in This report presents the results of the asbestos inspection conducted by Forensic Analytical Consulting Services, Inc. for the above referenced project. Results of the inspection are summarized in Appendix A. Drawings depicting ACM and sample locations are presented in Appendix B. A detailed laboratory report and chain of custody forms are contained in Appendix C. 2.0 FIINGS The results of the samples indicate that asbestos was detected at the site. A complete table of the samples taken and materials assumed to contain asbestos can be found in Appendix A. 3.0 RECOMMEATIONS Materials for which sample analysis by PLM results in greater than one percent asbestos (for any one sample collected from a homogeneous material) are classified as ACM under regulations promulgated by, but not limited to, the following agencies: federal EPA and federal OSHA. The agencies use the following definitions: Federal EPA (Oregon DEQ): materials containing greater than one percent asbestos are ACM Federal OSHA (OR-OSHA): materials containing greater than one percent asbestos are ACM For detailed regulatory requirements in specific situations, Forensic Analytical should be consulted, or the applicable regulations should be examined. All materials identified were classified by condition. Materials in "good" condition should be maintained in place following the OR-OSHA operations and maintenance requirements. Materials in "Fair" condition should have patch and repair activities performed to address any damaged areas. Materials in "Poor" condition should be addressed through removal, repair and/or encapsulation.

8 PORTLA STATE UNIVERSITY ASBESTOS SURVEY SCIENCE BUILDING SW 10 TH AVE., PORTLA, OR REVISED JULY 21, 2008 FORENSIC ANALYTICAL PROJECT #PJ4385 PAGE 4 The following materials are classified as in "Poor" condition in this building: The fireproofing above the fourth floor ceiling is deteriorating and delaminating. During the inspection, delaminated fireproofing material was observed on the top of the ceiling tile where the fireproofing is installed. The pipe fitting insulation on the sprinkler risers on the north and south end of the roof is deteriorated. 4.0 METHODS Materials suspected of containing asbestos were sampled in accordance with the federal EPA AHERA protocols. Materials determined by the inspector to be non-suspect, such as wood, metal, glass, and fiberglass insulation, were not sampled. Destructive sample techniques were not used during the inspection. Additional suspect building materials may be present in areas that were inaccessible, unsafe to inspect, or obscured from view during the inspection process. Suspect materials were grouped and classified as homogeneous materials based on their appearance, usage, and age of the building. Representative samples of each homogeneous material were collected for laboratory analysis. Where previous sample data exists, one confirming sample was collected of materials that previously tested positive. Additionally, where multiple samples of a given homogeneous material were collected, the set was analyzed to first positive. The unique sample description ID was developed specifically for PSU. The sample ID includes; the PSU building ID; the homogeneous material number; followed by a unique material code (FT = Floor Tile); and lastly the sample number. Samples were collected in such a manner as to minimize release of the material into the surroundings. Material type, sample number, sample location and other pertinent information were recorded at the time of sampling. Each sample was placed in a sample container labeled with a unique sample number and submitted to Forensic Analytical s NVLAP-accredited laboratory for analysis under chain of custody documentation. Samples were analyzed in accordance with EPA Method 600/R , using PLM with dispersion staining and using visual area estimation to determine percent asbestos content. This method allows for the identification of the primary types of asbestos used in building materials. The lower limit of detection for this method is one percent. Samples containing less than one percent asbestos by PLM with visual area estimation are reported as Trace. 5.0 LIMITATIONS Forensic Analytical did not inspect subsurface areas for asbestos. ACM such as underground waterproofing coatings, asbestos-cement water pipe, electrical ducts, or other subsurface materials or equipment may be present beneath the site. Forensic Analytical did not disassemble building equipment; such as fans, ducts, elevator equipment, and electrical equipment. Consequently, equipment may contain untested gaskets, internal components, overspray of building materials and the like. It is also common for carpet to be installed over previously installed floor materials. If the aforementioned materials or any other untested suspect materials are encountered during

Forensic Analytical has performed this asbestos sampling in accordance with generally accepted methods and practices of the profession, and consistent with that level of care and skill ordinarily exercised by reputable environmental consultants under similar conditions and circumstances. No other representation, guarantee or warranty, express or implied, is included or intended in this asbestos inspection report. Respectfully submitted, Reviewed by, Dan Rouse Noal Kraft

Representative subsamples were weighed and ashed for 6 hours, at 480 C. The ashed residues were ground in concentrated hydrochloric acid. The acidified residue was resuspended in 100 ml particle-free water and sonicated. Aliquots of this suspension were brought to >20ml and filtered through 0.22um pore-size mixed cellulose ester (MCE) membranes. After air-drying, these membranes were collapsed, etched, carbon-coated, and mounted on 200-mesh copper TEM grids. Analytical Method: The analysis was performed on a Philips CM12 TEM at 100kV accelerating voltage. An extended low magnificaton analysis (~2,500x) was performed for large asbestos structures, followed by a high magnification analysis (~19,000x) for smaller asbestos structures. Asbestos structures were identified by morphology (Yamate Level II definitions), qualitative selected area electron diffraction (SAED), and energy dispersive x-ray analysis (EDX). In addition, the length and diameter of each asbestos structure were recorded. Data Reduction: The asbestos concentration in each sample was calculated by first determining the volume of each asbestos structure counted, and then using magnification and density conversion factors to determine asbestos mass. The mass detected in the high magnification analysis was then normalized to the number of grid openings analyzed and the aliquot volume filtered for the low magnification analysis. Since a known residue mass was passed through a known filter area, and the filter area analyzed is also known, the normalized asbestos mass in the residue can be determined and then back-calculated to the weight percent asbestos in the original sample.
