Pool Construction, Inc. X5,400 Aqua Logic X5,600 These prices reflect the purchase and installation of the main drain and suction trench. In the attached memo from Mr. Dahms, our engineering consultant on this project, it is suggested to include an additional X5,000 if we will need to place a baffle over the slide and play feature suction pipes that are located in our water recycling trench. There is some debate between the Consumer Product Safety Commission and the language in the Federal law regarding this issue. At the time this memo was prepared for the City Council, our engineer was still investigating this issue. It is my recommendation to retain Pool Construction, Inc. for the purchase and installation of the upgraded drain project. In addition, to allow for up to X5,000 in additional funding if we do need to retrofit baffles on our play feature suction piping. Thank you!

This one is from Aqua Logic, the other one that I am waiting on is Pool Construction. PCI said that I would have it before 8 am this mornng. As soon as I get it, I will send it to you. I also wanted to bring to your attention that Wednesday morning I called Consumer Product Safety Commission, the agency overloolang the VGB issues, and discussed with them the situation we have with your main drains. Due to CPSC not having solutions to every situation out there, there is a chance that we may need to do something a little different with the two main drains than what I have asked them to propose on. They told me that they would get back to me before the end of the day, but they didn't. Here is quick explanation. When pool was designed, since it was gravity flow from main drains, each main drain cover was designed to handle half of the required flow. This was the typical standard for designers in any gravity flow situation. The current way the law is written, we only need to have approved covers and gravity flow, which we have. However, they have notes on some covers that they need to handle 100% of the flow, which is a problem as the main drains are designed for half the flow. I am confident what we have here is going to meet the requirements as written in the law, but I will need CPSC to verify. The other issue is whether you want to bring the sumps up to current ANSI standards. This would require that we put on a baffle over the slide and play feature suction pipes in the trench. This can be done rather simply, but would be an added cost to this work. CPSC says you don't need to do this, but from a liability stand point, you may want to do that. My recommendation is that you approve the low bidder but include another $5,000 to accomodate these two potential issues to be covered. Give me a call to discuss if you would like. Thai~lcs. Jody A.
