MOUNDS VIEW City of Mounds View Staff Report Item No: 7G Meeting Date: September 23, 2613 Type of Business: Council Busi ess Administrator Review: To: Honorable Mayor and City Council From: Nick DeBar, Public Works Director Item Title/Subject: Resolution 8158, Authorizing Inspec, Inc. to Perform Final Design Services and Prepare Bidding Documents for Reroofing and Masonry Renovation of Ground Reservoir, Booster Station, and Well House No. 2 Background: The City authorized Inspec, Inc. to perform a roof management plan in October 2010 and an exterior wall management plan in May 2012 for all sixteen municipal facilities. These plans provide a detailed evaluation of repairs needed and provide a timeline for replacement if required. Public Works has been working with these plans to prioritize and budget the various repairs and improvements to the various facilities owned by the City. The Booster Station, Well House No. 2, and Public Works Facility (1986 addition) are scheduled for reroofing in 2014 and all have some level of masonry renovation needed. The ground reservoir has significant masonry renovation needs and its roof is in need of improvements. Inspec was authorized to perform preliminary engineering design and analysis to determine the best approach to fixing the ground reservoir wall and roof (Nov. 2012 — Res. 8020). Work included investigations by removing test openings in the exterior wall and structural analysis to determine possible roofing systems. Inspec completed this phase of the project and provided Public Works with final reports to be used in final design and bidding document preparation. Discussion: A combined reroofing and masonry renovation project is proposed for the Booster Station, 2MG Grounds Reservoir, and Well House No. 2. The booster station and reservoir were constructed in 1968 and the well house in 1964 with none or little improvements to the exterior systems. The entire Public Works Facility is also due or past due for reroofing and masonry renovation, but no improvements are recommended since demolition and construction for a new building is planned to occur in 2016. Reroofing and masonry renovation are compatible activities and will deter having to undo or redo improvements if done as separate projects. Preliminary engineering has identified reroofing the booster station and well house with a built-up roofing system and installing a fully -adhered EPDM single -ply membrane to the reservoir top. Additional inspections and evaluation of the wall coatings are needed inside the reservoir structure. These inspections require emptying the 2 million gallons inside the reservoir and entering the confined space. Public Works is planning to empty the reservoir this fall and perform cleaning maintenance by removing sediment and other mineral deposits. Interior wall coating inspections are anticipated to occur at this time. The reservoir will be required to be emptied again next year during the reroofing and masonry renovation, at which time any improvements to the interior wall coatings will be performed as part of the project. Public Works solicited a fee proposal from Inspec to perform final design and prepare bidding documents for a public bid of the project. Inspec provided a fixed fee of $15,900 to perform these services. Public Works also solicited a fee proposal from KLM Engineering to inspect and evaluate the interior wall coatings of the reservoir, including any unsafe OSHA conditions. KLM provided a fixed fee of $3,800 for these services and recommendations for inclusion into the bidding documents.
