CITY OF BOZEMAN, MONTANA MORRISON MAIERLE By________________________________ By_____________________________ Jeff Mihelich, City Manager Print Name: Jay Fisher Title: Project Manager APPROVED AS TO FORM By_______________________________ Greg Sullivan, Bozeman City Attorney DocuSign Envelope ID: C72D3F33-7BBF-4042-98BB-03FD61CCA781 Bozeman Operations Manager Travis Eickman --------- ---------- EXHIBIT A DocuSign Envelope ID: C72D3F33-7BBF-4042-98BB-03FD61CCA781 March 17, 2022 City of Bozeman Attn.: Mike Gray and Max Ziegler Facilities Superintendent and Facilities Project Coordinator 20 E Olive Street Bozeman, MT 59715 Re: Swim Center Tier 1 Seismic Evaluation and Initial Roof Truss Assessment and Analysis Dear Mike and Max: Thank you for this opportunity to continue assisting the City with the assessment of and long-term planning for the Swim Center. As requested, the following is our understanding of the scope of services, fee, assumptions, and limitations associated with performing a Tier 1 Seismic Evaluation for the building and completing an initial visual structural assessment of the long-span wooden roof trusses over the natatorium. Assumptions/Limitations Our structural engineering fees were based on the following assumptions and limitations: • Existing drawings and previous condition reports have been provided to MMI. • MMI will perform a Tier 1 Seismic Evaluation of the Swim Center and prepare a statement to supplement the evaluation checklist if necessary. We understand ladders or other means of access necessary to perform the Tier 1 Seismic Evaluation will be provided by others on site. • MMI will perform a preliminary structural analysis of the wooden roof trusses spanning the natatorium using the information currently available to our team. Please note that this analysis will assume that all members are structurally sound with no failures and will not take into consideration the current condition of the members. The purpose of this analysis is to better understand the system behavior and end reactions as well as failure modes with which the system may be predisposed. • MMI will perform a non-destructive, limited visual assessment of the long-span wooden roof trusses over the natatorium. We understand that access will be limited, and, due to the safety of our personnel as well as access constraints, a thorough, unobstructed assessment of the full length of the trusses is not possible at this time. Our visual assessment will be limited to those items which can be observed from the scaffolding on the pool deck. • We understand that scaffolding will be provided by others for our use during the assessment. We understand the ceiling tiles will not be removed prior to our assessment and that MMI will be responsible for removing ceiling tiles as required to access the trusses and for re-positioning them following the assessment. MMI will not be responsible for replacing ceiling tiles that break or are damaged during the process of removing and repositioning the tiles. The fee below includes budget for these services. • The truss assessment does not include scope / fee for providing specific options and recommendations to update the system if required, preparing a cost estimate, nor DocuSign Envelope ID: C72D3F33-7BBF-4042-98BB-03FD61CCA781 bringing a specialist (i.e., wood scientist or other) to provide a more specialized investigation of the wood truss chords. These services may be deemed necessary pending the findings of the assessment. Should these services be deemed necessary we can amend our scope and fee at that time. • MMI will develop a report for the City documenting the findings of the Tier 1 Seismic Evaluation and truss assessment and will provide recommendations for moving forward. Please note that this initial visual assessment of the roof trusses is intended to serve as a follow-up to our initial conditional assessment, and that the comprehensiveness of this visual assessment will be limited by the limited ceiling and scaffold access which is being provided. Only those portions of the existing framing which are accessible and viewable will be evaluated for potential damage and deterioration. As a result, we will be unable to determine with a high level of certainty the overall integrity of the structural roof system and our conclusions regarding the overall structural adequacy of the roof framing system and condition of its members will be correspondingly limited. Only after each roof truss is fully exposed and visually evaluated will we be able to provide a comprehensive assessment of the structural adequacy of the roof system. • The anticipated project schedule is as follows: o Assessments will be completed by mid-April of 2022. o A draft of the reports documenting our findings will be delivered to the City by end of April 2022. Scope of Services and Fee The following is our understanding of the scope of services: • Draft and submit the City’s Standard Agreement for approval. • Tier 1 Seismic Evaluation o Travel to the Swim Center and perform a Tier 1 Seismic Evaluation of the building o Take photographs to document the existing conditions. o Take relevant measurements of existing members to determine the extent of their damage / deterioration. o Take measurements to determine the vertical alignment of walls using a level, plumb bob, or similar device. o Complete the Tier 1 Seismic Evaluation checklist and prepare a statement to supplement the checklist if necessary. • Analysis and Initial Visual Assessment of Wood Roof Trusses o Perform analysis and calculations using current building code gravity and lateral loads to verify the structural stability and strength of the trusses spanning the natatorium to better understand their behavior and reactions, as well as the failure modes with which the system may be predisposed. o Travel to the Swim Center and perform a visual assessment of the roof trusses from scaffolding supported by the pool deck. o Take photographs to document the existing conditions. o Based on the results from the above tasks, prepare a report documenting the findings of the assessment and provide general recommendations for possible options for repair (if necessary / possible) and for the next steps moving forward. DocuSign Envelope ID: C72D3F33-7BBF-4042-98BB-03FD61CCA781 Please note that the scope of services does not include providing specific options and recommendations to update the system if required. • Present the Tier 1 Seismic Evaluation and assessment report to City representatives. For the scope of services outlined above, we have estimated a lump-sum fee of $18,500. We are agreeable to negotiate additional services if additional scope items are added or found to be necessary. Once we receive your approval of this proposal, we will proceed with beginning our work on this project.
