This task included several individual tasks to include: - Scheduling of asbestos surveys - Collection of asbestos samples - Laboratory testing - Analysis of laboratory findings - Development of ACM scope of work Approximately 7 — 9 samples were taken at each condominium to include gypsum board joint compound, window glazing, and exterior window and door caulking. In addition, random exterior stucco samples were collected on both the "walkway" and "courtyard / balcony" building elevations. Asbestos Abatement Requirements The degree of required asbestos abatement depends entirely on laboratory test results of the samples collected: No presence of Asbestos Containing Materials (ACM) No abatement is required A presence of <1% of Asbestos Containing Materials (ACM) Only OSHA worker safety precautions need to be performed such as respirators for workers when cutting or sanding, additional poly curtain wall around cutting / sanding area and the use of a HEPA vacuum to capture dust. A presence >1% of Asbestos Containing Materials (ACM) Full abatement is required to include air sealed containment, air sampling, safety barricades, worker clearances in containment area, full worker protective suits, worker decontamination, and hazardous waste ID and disposal. KWBTS Building B Test Results In mid - November 2017, samples were taken at multiple surfaces at each of the participating KWBTS Building B condominiums to include gypsum board joint compound, window glazing, exterior window / door caulking, and random exterior stucco at "courtyard" and "walkway" building elevations. The laboratory test results received in mid -March 2018 showed that 100% of all samples collected showed no presence of ACM in all surfaces: gypsum board joint compound - no ACM window glazing - no ACM exterior window & door caulking - no ACM exterior stucco - no ACM KWBTS Building C Test Results During the December 2017 to February 2018 time period, samples were taken at multiple surfaces at each of the participating KWBTS Building C condominiums to include gypsum board joint compound, window glazing, exterior window / door caulking, and random exterior stucco at "courtyard" and "walkway" building elevations. The laboratory test results received in late -May 2018 showed no presence of ACM in three (3) of the surfaces: window glazing - no ACM exterior window & door caulking - no ACM exterior stucco - no ACM However, test results showed ten (10) samples of the gypsum board joint compound contained <1% of ACM in units C212, C215, C217, C221, C304, C306, C307, C307S, C311 and C317. Since the presence of ACM is less than 1 %, only OSHA worker safety precautions will be required in these 10 condominiums. KWBTS Building A Test Results During the mid -April 2018 time period, samples were taken at multiple surfaces at each of the participating KWBTS Building A condominiums to include gypsum board joint compound, window glazing, exterior window / door caulking, and random exterior stucco at "courtyard" and "walkway" building elevations. While we have not yet received laboratory test results for three (3) of the surfaces (gypsum board joint compound, window glazing, exterior window & door caulking), in late July 2018, we received laboratory test results for the exterior stucco which showed the following: "Walkway" Elevation Stucco Laboratory test results showed that 22 of the 24 random samples (90 %) (taken on all floors 1 -6) showed a <1% presence of ACM, while 2 samples (taken at adjacent condominiums) showed a 2 -5% presence of ACM). Based on these results, it was determined that OSHA safety precautions will be required for all window, door and PTAC work performed on the "walkway" building elevation, with the exception of the 2 condominiums where full abatement will be required (containment, safety barriers, air sampling, full worker protective suits, containment release, and worker decontamination). "Courtyard" Elevation Stucco Given the results for KWBTS Building B and C, which showed no presence of ACM on either "walkway" or "courtyard" elevations, only 6 samples were taken at the "courtyard" side of Building A on the ground floor. Unfortunately, the laboratory test results showed a <1% presence of ACM (similar to the "walkway" elevation) on 1 sample and a 2 -5% presence of ACM) on the remaining 5 samples. Summary & Recommendation In addition to being completely inconsistent with Building B and C, the Building A laboratory results suggest that full abatement (containment, safety barriers, air sampling, full worker protective suits, containment release and worker decontamination) may be required on the entire Building A "courtyard side," unless additional testing is performed. There are only two (2) options to consider: Option 1 With our limited testing results, assume that 100% of all 65 KWBTS Building A "courtyard / balcony" elevations are "hot" (2 -5% ACM level) requiring full asbestos abatement on all acoustic window and door installations, HVAC installations, and during the removal and infilling of PTAC units, on the "courtyard / balcony" building elevation. Option 2 Conduct supplemental asbestos testing in all 65 KWBTS Building A Units on the "courtyard / balcony" building elevation in an effort to limit the level of required asbestos abatement during the future KWBTS Building A NIP construction. Given the high cost of asbestos abatement and its negative impact on construction schedule timelines, Option 1 would be very expensive. For example, assuming a $100,000 cost for NIP construction in each Building A condominium, full asbestos abatement could add up to 50% to this cost ($50,000). Full asbestos abatement, especially on 6 -story scaffolding, could add multiple days to the construction period in each condominium, - resulting in a longer period that property owners would be required to relocate from their condominium. Option 2 would be much more cost effective, as it reduces the potential for required full asbestos abatement in KWBTS Building A condominium units that show stucco samples with a <1% ACM level. In summary, testing the exterior stucco of all 65 KWBTS Building A condominiums on the "courtyard / balcony" elevation will have the potential to greatly reduce the amount of required full asbestos abatement during the future Building A NIP construction. The cost of additional asbestos testing and associated laboratory results has the potential to greatly outweigh the cost of 100% asbestos abatement. The following scope of work (see below) has been developed to conduct Option 2. . SCOPE OF WORK SUPPLEMENTAL ASBESTOS TESTING OF KWBTS BUILDING A (65 UNITS) — COURTYARD ELEVATION Consultant Team Overview The Supplemental Asbestos Testing of KWBTS Building A (65 units) — Courtyard Elevation task will require an array of tasks to be completed by THC and their environmental sub - consultant, EE &G. The THC Director of Acoustical Services will act as the Project Manager of the THC Consultant Team during this task, reporting directly to the Airport's Noise Program Coordinator. The THC Project Manager will be supported by an Assistant Project Manager from the THC Atlanta headquarters office. This work will be performed by the following disciplines. • THC, Inc: - The Project Manager, THC, Inc. (THC) will provide overall program management services as necessary. THC will provide database services and project scheduling, along with interaction with all participating property owners and tenants. The Director of Acoustical Services ($256.39) will act as Project Manager and will have overall responsibility for all daily project tasks and activities. THC will also utilize the services of an Assistant Project Manager ($115.00) for both management and administrative support from the Atlanta headquarters office. • EE &G — The Environmental Consultant will provide all services associated the with the Supplemental Asbestos Testing of Building A (65 units) — Courtyard Elevation task to include asbestos sample collection, laboratory analysis, analysis of test findings and development of final ACM scope of work for each condominium. EE &G will utilize the services of the Principal, Senior Technical Advisor, Senior Project Professional and Administrative Assistant. Supplemental Asbestos Testing — KWBTS Building A (65 Units) The Consultant (THC, EE &G) will be required to complete supplemental asbestos testing in 65 KWBTS Building A condominium units on the "courtyard / balcony" building elevation. This process will include several sub - tasks: Scheduling of Asbestos Surveys The Consultant will schedule appointments for each of the 65 KWBTS Building A condominiums, to allow for the collection of require number of asbestos samples. The following is an approximation of the survey schedule: Monday afternoon 1 pm — 5pm: 10 condos Tuesday morning 8am — 12noon: 9 condos Tuesday afternoon 1 pm — 5pm: 10 condos Wednesday morning 8am — 12noon: 9 condos Wednesday afternoon 1 pm — 5pm: 10 condos Thursday morning 8am — 12 noon: 9 condos Thursday afternoon 1 pm — 5pm: 8 condos Collection of Asbestos Samples During the scheduled Asbestos Survey, the Consultant will collect two (2) stucco samples in each of the 65 KWBTS Building A condominiums (sliding patio door, PTAC wall location). Laboratory Testing After the collection of samples for each of the 65 KWBTS Building A condominiums, the Consultant will ship them to an accredited scientific laboratory for analysis and presence of asbestos containing materials (ACM). Analysis of Laboratory Findings The Consultant will review and analyze sample test findings for each of the 65 KWBTS Building A condominiums. This analysis will provide a summary of ACM presence in all 65 condominiums. Development of ACM Scope of Work Based on the analysis of laboratory findings, when sample results show the presence of ACM, the Consultant will develop a custom ACM Scope of Work for each condominium that can be included in the future bid documents. Reimbursable Expenses Notes: In this Task, the Consultant (Project Manager) and Environmental Consultant will need to budget costs for one (1) 5 -day trip. All costs will include related airfare, auto rental, per diem, shuttle, fuel, and parking costs for each Consultant staff. In addition, the Consultant will need to include all costs related laboratory fees, shipping and duplication. • T•H• Improving Your Community TRANSMITTAL 3300 Breckinridge Blvd. Suite 200 • Duluth, GA 30096 Telephone: 770.623.0520 Fax: 770.495.2384 www.thcinc.net Date: September 27, 2018 THC Project No.: PSO3 -S3 Attn: Beth Leto, Sr. Airport Business Manager Project: Key West NIP (FY 2018 -19) To: Key West International Airport 3491 S.
