City Council Meeting Minutes June 13, 2017 Page 4 of 11 Chris Kastelic, Sink Combs Dethlefs, stated the existing building was built on concrete slabs on grade, placed on recompacted soil. He stated the new soils report states there are expansive clays in the soil that could cause the slabs under the new expansion to move and it recommends a modified foundation Mr. Kastelic stated this is not a safety issue, but rather a concern that if there is slab movement it can cause damage to the building The rest of the foundation including walls, roof structure, and the envelope of the building, are not affected by this recommendation The existing building has the same slab construction and has not had any movement He noted the pools are not an issue as they are built on piers This redesign would increase the costs of the project by approximately $1.3M Should Council decide not to go with the redesign, the City will be responsible for any for future damage to the building if the slabs move Staff requests direction on whether to build the expansion with a crawl space foundation or to follow the current design and accept the risk of slab movement. There is the potential of applying for a DOLA grant to offset some of these costs, but there are no guarantees the funding will happen. Councilmember Maloney asked if there has been any movement in the current building over the past 20 years Mr. Kastelic said a visual inspection shows no movement Mayor Pro Tem Lipton stated he would like additional analysis At some point it becomes a question of nsk assessment. If we go with the additional cost there should be some discussion of ideas other than a general fund transfer such as value engineering or a fund loan. He stated he would like to deliver what was approved, but we need more detail about what cuts can be made to the design. Mr. Kastelic stated there is not likely much additional value engineering that could be done, at this point it would be removing specific items or programs from the building. Mayor Muckle asked for public comments. Deb Fahey, 1118 West Enclave Circle, stated her house was built near the existing Recreation Center and noted that in 27 years the basement floor has sunk about a 1/2 inch so she doesn't think it is a big issue as long as it is only the slabs that would be affected. If the Council does commit to the additional spending, she hopes it does not affect the green energy efforts in the building. Councilmember Keany asked if the decision was needed this evening or if it can wait until additional information is available Mr Kastelic stated the project is already behind schedule and if a decision is not made tonight it will further impact the schedule.
