Seismic Hazard Analysis Services Supplemental Agreement No.3 with Reid lVliddleton City Project No. 03-BG04, Contract No. 07-087 ISSUE Approve Supplemental Agreement No.3 with Reid Middleton for Seismic Hazard Analysis Services. BACKGROUND Reid Middleton was the only respondent to the Request For Qualifications and subsequently entered in to City Contract No. 07-087 for preliminary seismic hazard screening services (phase I) in the amount of $19,092.00. Reid Middleton began work on May 16, 2007 and submitted the fmal seismic hazard screening report on September 21, 2007. Supplemental Agreement No.1 was for a 90-day time extension, and Supplemental Agreement Number 2 in the amount of $5,240 included a time extension for adding three City facilities to the Seismic Hazard Screening Services Project (the Community Center, George Long Shops, and Minkler Shops were not included in the original contract). As recommended in the fmal report, the City facilities listed below will now be evaluated in detail using the industry standard ASCE 31 Seismic Evaluation Procedure described on page 2-2 of the final report. The City asked Reid Middleton to submit a supplemental agreement proposal with a scope and fee estimate to perform Tier 2 and Tier 3 seismic evaluations (phase II). Tier 2 evaluations provide analyses more refined than Tier 1, but are still limited to simplified linear procedures. Tier 3 evaluations are more detailed and use advanced analytical procedures. The attached Supplemental Agreement No.3 will include, but not be limited to the following services: . Tier 2 evaluations for: o Fire Station 53 . Tier 3 evaluations for: o City Hall o 6300 Building o Fire Station 51 o Fire Station 54 o Tukwila Community Center P:\PUBWORK5\PROJECTS\A- BG Projects\03BG04 Seismic Screening Oty Fadlities\Info Memo Seismic Analysis 07-087 Supplement #3.doc Page 2 October 22, 2007 Mayor Mullet .

DATED this CITY OF TUKWILA Reid Middleton Steven M. Mullet, Mayor David B. Swanson, Principal P:\PUBWORKS\PROJECTS\A- BG Projects\03BG04 Seismic Screening City Facilities\07-087 Supplemental Agreement 3.doc EXHIBIT A Scope of Services A. Project Understanding This work is a continuation of the Phase I preliminary seismic screening and evaluations of City of Tukwi1a (the City) facilities. Based on the fmdings and recommendations contained in the fmal report from the preliminary seismic hazard screenings and evaluations, dated September 21, 2007. The City decided to progress with Phase II detailed seismic evaluations of the following buildings; City Hall, 6300 Building, Fire Stations 51, 53 and 54 and Tukwila Community Center. In addition to the seismic safety for these buildings, this work will also provide the City with preliminary structural concept retrofit designs, an assessment on how functionally useful the buildings are, preliminary geotechnical information, and preliminary costs for retrofitting the buildings and replacing the buildings. The purpose of this of this study is to provide the City with enough information to determine if the buildings should be renovated or replaced. B. Scope of Services Reid Middleton will provide the following services: 1. Conduct site visits to each of the buildings listed in Item 2 and Item 3 in order to gather additional information required for the seismic evaluations. The City will coordinate access to each of the sites with the building occupants. 2. Perform an ASCE 31-03 Tier 2 deficiency-based structural evaluation of the building listed below based on the findings from the ASCE 31-03 Tier 1 evaluation. As part of the Tier 2 evaluation, efforts will be made to obtain a complete set of the buildings record drawings. Fire Station 53 4202 South 115th Street Tukwila, WA 98168 3. Complete ASCE 31-03 Tier 3 building seismic evaluations of the facilities listed below. Reid Middleton will perform ASCE 31-03 Tier 3 evaluations using ASCE 41-06 component-based procedures. The buildings listed below will be evaluated for Immediate Occupancy structural performance under the 10%/50-year seismic event. Forces will be reduced by 25 percent for evaluation purposes. Nonstructural performance will not be evaluated at this time. The results of the evaluation will be used to determine the extent of seismic deficiencies in both the primary and secondary structural elements and components throughout the buildings. The detailed evaluation will provide the basis for the recommended seismic rehabilitation strategy. Tukwila City Hall 6200 Southcenter Boulevard Tukwila, WA 98188 6300 Building 6300 Southcenter Boulevard Tukwila, WA 98188 Fire Station 51 444 Andover Park East Tukwila, WA 98188 Fire Station 54 4237 South 144th Street Tukwila, WA 98188 Tukwila Community Center 12424 42nd Avenue South Tukwila, W A 98168 4. Perform limited preliminary concept-level design to assess the feasibility of basic seismic rehabilitation strategies and design concepts for the buildings listed in Item 3. Rehabilitation alternatives will be evaluated for Immediate Occupancy structural performance under the 1 0%/50-year seismic event using ASCE 41-06 criteria. 5. Provide preliminary opinion of probable costs for the concept-level retrofit designs provided in Item 4. The preliminary opinion of probable costs will be given in a cost per square foot format and with a range of values. This information will be used to help determine the feasibility of retrofitting the buildings versus constructing new buildings. 6. Architectural Services a. Capital Facilities Assessment Document the age, condition, and functionality of the buildings in Item 3. Services would include: (1) Tour these existing facilities. Perform a visual inspection and document significant property features, conditions, constraints, and/or encumbrances. (2) Review documented property information and previous construction plans provided by the City of Tukwila. (3) Together with City staff and division heads, identify the functional and operational inefficiencies at each building. This could include inadequacies of the particular room or space, obsolescence, lack of specialized equipment, inefficient circulation, and/or the like. b. Building and Site Diagrams Provide preliminary building and site diagrams to confirm if the existing buildings can adequately support any projected building additions and/or replacement plans. Also known as "test-to-fit" diagrams, this exercise would inform the City of potential inadequacies in meeting the identified operational requirements. This could assist the City of Tukwila in their decision to renovate or replace anyone or more of these particular buildings. c. Capital Facility Financial Models Assist in estimating the project soft costs (i.e. sales tax, A&E fees, permits, special consultants, land acquisition, furnishings, equipment reasonable contingencies, and the like). Overall project timelines would be incorporated into the cost modeling to capture the cost of inflation over time. d Stakeholder Presentations Assist with presenting the fInal capital facility recommendations to individual stakeholder groups. These services could include preparation of graphic materials (large format renderings, PowerPoint presentation, handouts, narratives, and the like). 7. Provide preliminary geotechnical recommendations for the sites listed in Items 2 and 3 and the sites listed below. These recommendations will be based on the geotechnical engineer's knowledge ofthe local geologic hazards and features. No site borings will be conducted. This information will be used to help determine the feasibility of retrofItting the buildings versus constructing new buildings. George Long Shops 14000 Interurban Avenue South Tukwila, WA 98168 Minkler Shops 600 Minkler Boulevard Tukwila, WA 98188 Fire Station 52 5900 South 147th Street Tukwila, WA 98188 8. Prepare a report summarizing the fmdings of the ASCE 31-03 evaluations for the buildings listed above in Items 2 and 3. The report will also include a narrative and sketches ofthe preliminary concept designs from Item 4 above and the opinion of probable cost from Item 5. A draft report will be submitted to the City for review and comment, followed by a fInal report. Four copies of the report will be furnished at each submittal. In addition, one electronic copy of the fInal report will be provided. In conjunction with the submittal of the draft and fInal reports, Reid Middleton will attend a meeting to present our findings and recommendations to the City.
