Demolition of Existing Tile Coping and Installation of New Tile Coping

The City of Missoula Parks and Recreation Department (City) is requesting proposals for the demolition and disposal of the existing tile coping and to provide and install a new tile coping at Splash Montana, located at 3001 Bancroft, MT 59801. The City will select one (1) Supplier to provide the equipment, materials, and labor for the project outlined in this request.

Scope of Work

Facility Description & Project History

Splash Montana is an outdoor water park at 3001 Bancroft Street in Missoula, Montana. Original construction was completed in June of 2006. At this time, the Lazy River and Pond pools were opened to the public. The pools are Gunite and plaster pools with various play features. The max depth of each pool is 3 feet 6 inches. The Lazy River pool has tiled edges (horizontal and vertical) that make up about 3000 linear feet of water line. The Pond has about 50 feet of similarly tiled water line. Both pools have areas where a stainless steel gutter system has been installed.

Within a few years of construction, the tile in the Lazy River in large spots began to delaminate and pop off. Most of this would occur in the Springtime after the final thaw cycle. We now believe that much of this was caused by the freeze/thaw cycle. Staff would affect simple, quick repairs to ensure the pool shell was safe for the operating season but would have to repeat the process each year with increasingly larger sections of tile. The Lazy River encircles a dirt and vegetation area that is the ground base for the slide tower (the slides deposit riders into the splash down section of the pool). We now believe that melt water and rain would seep into the concrete and Gunite from behind the tiles, degrading the sublayers and eroding the tile thin set.

In the spring of 2016, a retile project was completed to address these issues. At this time new tiles were installed using a cement underlayment. However, the probable cause of the tile delamination was not addressed as the issue was not at that time fully understood. Thus, within a year or two, the tile delamination resumed, and the spring quick fixes continued. This current project is to ensure that the correct tile and underlayment is installed to provide proper adhesion and surface protection.

Work to be Performed by the Selected Bidder

Lazy River:

1. Demolish and remove water line tile coping. The interior and exterior perimeter of the Lazy River measures out to 1000 linear feet. Width of tile, including vertical and horizontal is roughly 3 feet. Currently consisting of 6x6 inch tile and 8x8 inch tile. This will need to be done without damaging the existing plaster walls and pool bottom.

2. Clean and prepare the underlying shell and edges. Repair Gunite and seal cracks where needed.

3. Identify problem areas which may be the result of melt water intrusion from the planter areas and identify low points. Install proper drainage (field tiling or similar) and waterproofing (waterproofing sealant or similar) on the backside of the Gunite to protect the new tile work.

4. Apply a leveling mortar to create the perfect vertical and curved shape (Brown Mud or similar product). This mortar bed should “true up” the pool’s walls.

5. Apply a Waterproof Epoxy as a secondary barrier to protect the Gunite and brown coat by providing a specialized, non-porous membrane (Use Latapoxy 300 Adhesive, an epoxy adhesive provided by Laticrete, or similar).

6. We are open to most coping options, the bid needs to include submittals for the type of product you will use and it should match all the way around the perimeter. Some of the options we are interested in include 1 inch tile with bullnose (or similar product), an epoxy style pour in place (or similar product), or ecoFINISH (or similar product)

7. Install selected coping around the perimeter of the Lazy River Pool (except for the stainless gutter areas). Install new coping on the vertical and horizontal surface to butt into the existing plaster and concrete. Horizontal surface should be slip resistant rated for standing water (wet DCOF of .6 or R12 or approved equal). Grout installed should be epoxy based and rated for underwater use.

8. Chip out delaminating plaster around the entry steps and tile edges; check for structural cracking and repair with epoxy injection. Replaster areas of delamination.

9. Sweep and dispose of all demolition and construction refuse leaving a turnkey environment.

Pond Pool:

1. Demolish and remove 60 linear feet of water line tile coping. Currently consisting of 8x8 inch tile.

2. Clean and prepare the underlying shell and edges. Repair Gunite and seal cracks where needed.

3. Apply a leveling mortar to create the perfect vertical and curved shape (Brown Mud or similar product). This mortar bed should “true up” the pool’s walls.

4. Apply a Waterproof Epoxy as a secondary barrier to protect the Gunite and brown coat by providing a specialized, non-porous membrane (Use Latapoxy 300 Adhesive, an epoxy adhesive provided by Laticrete, or similar).

5. We are open to most coping options, the bid needs to include submittals for the type of product you will use, and it should match all the way around the perimeter.

6. Install selected coping around the perimeter of the Lazy River Pool (except for the stainless gutter areas). Install new coping on the vertical and horizontal surface to butt into the existing plaster and concrete. Horizontal surface should be slip resistant rated for standing water (wet DCOF of .6 or R12 or approved equal). Grout installed should be epoxy based and rated for underwater use.

7. Sweep and dispose of all demolition and construction refuse leaving a turnkey environment.

Interested respondents shall come prepared to inspect the work site and provide contact information including: Name, business name, phone & text #, and email address with Facility contact during the prebid site inspection. If any alterations are made to the scope of work or if answers to questions asked during either pre-bid site inspection, the Facility contact will share the information with all perspective bidders no later than May 25, 2026.

A Liquidated Damages Clause will be included in the Agreement based on calculated revenue loss per day should the project go past the allotted time frame.
