Brookglen Pool Uplift - Report & Recommendation December 16, 2009 Overview On Monday November 23rd staff discovered that the Brookglen Swimming Pool had uplifted approximately 12 inches over the weekend. Staff called Curtis Morgan, a swimming pool consultant for Paddock Southwest, LLC, a reputable pool construction and repair company in the area. Mr. Morgan inspected the pool and issued a report on the conditions (see attached report from Mr. Morgan). Cause Mr. Morgan concluded that a return line from the main drain pump to the pool broke at some point over the weekend, and began pumping water under and around the pool, instead of back into the pool. The main drain pump continued to pump water out of the pool, with no water returning, thus emptying the pool of water. The additional water on the outside of the pool, coupled with rain over the weekend, and the water being removed from the pool, caused the hydrostatic pressure outside the pool to surpass the weight of the pool, which made the pool "float out of the ground like a boat would float in water" . Condition of Uplifted Pool The pool suffered extensive damage with numerous cracks appearing laterally across the bottom and up the sides of the pool. Mr. Morgan and Mr. Whitfill inspected the pool again on December 1st and observed that a number ofthe cracks penetrate completely through the pool shell and have subsequently begun to widen, in some cases up to W' wide for a number offeet. In addition, it was observed that the pool shell is only 4 to 5 inches thick which is about half the normal thickness for commercial pools ((10"-12") in the deep end. Also the reinforcement steel seen through the cracked areas appeared to be inadequate for a pool ofthis size. Mr. Morgan's opinion is that the Brookglen Pool has "sustained overwhelming structural damage and any attempt to repair the shell in the condition that exists now would be a waste of money" due to the substantial cracking, the thinness of the original construction, and the fact that the entire circulation system would require replacement. Estimated Cost of Repair/Replacement Mr. Morgan indicated that the pool could be repaired by constructing a new shell inside the existing shell and tying the two together; then re-plumbing the entire pool. He estimates the cost of repair of the pool, at $200,000 but stresses that there is no guarantee that the pool will last any substantial length of time. He estimates the cost of a new pool of the same size and configuration, including demolition of the old pool, at approximately $350,000, and a new pool with play features (like San Jacinto Pool) at $500,000. While the City carries liability insurance on its pools, only the bathhouses are covered by property insurance, which is fairly typical according to TMl risk management. The City Council had awarded a bid to Hull & Hull, Inc. to construct a roof over the Brookglen Bathhouse at its November 9th meeting, but that contractor has not been issued a Notice to Proceed until the issue of pool replacement
