DESCRIPTION: The Fiscal Year 1998-99 Budget includes the Dublin Swim Center
Deck Replacement project. The project provides for the replacement of the pool deck and related
equipment at the Dublin Swim Center. The deck will be increased by approximately 6,000 square feet to
accommodate a group picnic area, bleacher seating, and storage for the pool cover and lane line reels.
Equipment to be replaced includes the 1-meter diving board stand and the lifeguard stands. New
equipment to be installed includes two starting platforms, new stanchions for backstroke pennants, picnic
tables, benches, trash/recycling containers, and bleachers. The City has received a Measure D Grant to
purchase and install picnic tables, benches and trash receptacles made from recycled products. The
balance of the project will be financed from the General Fund.
At the July 21, 1998 meeting of the Dublin City Council, the Council approved an architectural services
· agreement with Arch Pac, Inc. to prepare the final design and construction documents for the Dublin
Swim Center Deck Replacement project. Before proceeding with final design and construction
documents, Staff and the architect met with a representative from the Alameda County Health Department
to review the scope of the project. Based on this meeting, there are several changes to the scope of the
project, which are discussed below.
.t. The Dublin Swim Center was built in 1973 and since then, there have been several revisions to the
health code. Due to the size of the wading pool the current code requires that it be isolated from the
main pool and have its own filter and sanitation system. This will be accomplished by installing a
small filter and pump in the mechanical building and running new piping to the wading pool.
.~. The narrow size of the walkway between the two pools was another concern of the Health
Department. In order to widen this area, a portion of the main pool will be reconfigured with a new
wall and stairs for easier access to the pool.

Attachment 1 shows the existing layout of the pool; Attachment 2 shows the proposed layout of the pool
reflecting the increased deck size and the reconfigured walkway and pool wall.
In addition to replacing the deck and separating the pools, it is also recommended that the scope of the
project be expanded to provide for the removal of the fiberglass pool shell and the installation of new
plaster and ceramic tile. The fiberglass is nine years old and is nearing the end of its useful life. Last year
the City had to repair a portion of the fiberglass in the main pool, and more repairs are expected in the
future. Including the plaster as part of the deck project is more cost effective than continuing to repair the
fiberglass, or plastering in the future. This is primarily due to the fact that the pool will already be drained
as part of the deck project. Additionally the demolition work for the deck may damage the fiberglass and
tile which would require repairs to the fiberglass around the entire pool. Plaster was chosen over
fiberglass because it is has a longer life and ages more gracefully. When plaster begins to fail it becomes
rough, but not sharp like fiberglass, plaster can also be repaired without draining the pool.
Although not included as part of the current project, the next phase of the Dublin Swim Center Deck
Replacement project (scheduled for Fiscal Year 1999-2000) provides for the purchase and installation of
two drop-slides for the pool. As originally proposed, the two drop-slides would be installed in the deep
end of the pool in place of the 3-meter diving board that is being removed as part of the current project.
However, due to safety concerns the Health Department will not allow these types of slides to be
installed. Consequently, Staff has been working with the architect and Health Department to identify
slide options that would be safe and meet the health and safety code requirements.
Three different slides have been identified that could be accommodated on the site and meet the Health
Department's criteria (Attachment 3). The slide flumes that are available vary in length from 60 feet to
150 feet with one, two or three loops. The following is a breakdown of the cost of each slide:
Single Loop (60 feet)
Double Loop (90 feet)
Triple Loop (150 feet)
$ 55,770
$ 92,356
$125,686
Two of the three slide options exceed the amount currently identified in the 1998-2003 Capital
Improvement Program ($60,000). Depending on the option selected, the 1999-2000 Update to the Capital
Improvement Program may need to be adjusted to reflect the cost of the slide.
Of the three slide options identified above, the triple-loop slide would give a longer ride and provide the
most thrill for the rider. Neighboring cities have installed single and double loop slides but a triple-loop
slide would be the largest water slide in the Tri-Valley. Based on the experience of other cities, Staff
anticipates that the slide will generate additional revenue for the pool.
Staff is proposing to install the necessary piping and infrastructure for the slide as part of the current deck
project. This would be more cost effective and minimize the amount of damage done to the deck and pool
plaster when the slide is installed next year.
The Engineers estimate for the project is $427,236 which is approximately $36,000 more than the
available budget. Based on the current competitive bidding climate, the estimate includes a 20%
contingency as opposed to the more conservative amount of 10% which is typically used.
Staff recommends that the City Council authorize advertising of Contract 98-16 for bids. Additionally,
Staff recommends that the City Council provide input on the type of slide preferred so that the necessary
piping and infrastructure for the slide can be included with the plans and specifications for the deck
project.
