Any pre-existing damage to site or surrounding areas shall be documented by the Awardee. Failure of Awardee to document pre-existing damage(s) on site may result in an expectation by the City of Tampa that the damages are the result of the resurfacing work and as such would need to be repaired by Awardee.

Install new sleeves per manufacturer’s recommendation with appropriate footer (18” diameter round at top tapering down to square bottom minimum 30” per side, and minimum 42” deep overall). Repair court as indicated below based on existing court surfacing material.

3.3.1.1 For concrete courts, top of footer shall be level with court playing surface. Add any necessary fill dirt between edge of footer and underside of court, and compact to 95% density. Top of added fill dirt shall be level with bottom of undisturbed court when compaction is complete. Place sufficient depth concrete as needed over compacted fill dirt to match level of existing court and new footer. Court area immediately adjacent to sleeve shall be repaired to smooth, level surface after sleeve replacement is complete.

Top of added fill dirt shall be level with existing compacted soil level under layer of crushed subgrade material beneath asphalt layer when compaction is complete. Add layer of crushed material to match existing base layer under asphalt and compact as needed: top of crushed material shall be level with bottom of undisturbed court when compaction is complete. Apply tack coat over compacted base layer and concrete footer as a binder prior to application of asphaltic concrete. Add sufficient depth of Type S-III Asphaltic Concrete over compacted base to match level of existing court and cover top of concrete footer. Court area immediately adjacent to sleeve shall be repaired to smooth, level surface after sleeve replacement is complete.

3.3.2 All cracks shall be scraped and ground. All cracks of 1/8” width or more shall be patched with an acrylic patch mix and leveled with surrounding area.

Adjacent panels shall be overlapped a minimum of 3”. Wrinkles in the fiberglass material shall be corrected prior to application of the acrylic resurfacer. Completely mask and embed fiberglass material to hide the texture of the fiberglass membrane. Apply two texture/color coats of multipurpose acrylic fortified with silica sand over fiberglass overlay layer. Court colors shall be as noted in INSTALLATION 3.3.6.

3.3.9 According to the governing body of the sport(s) to be played on the surface, accurately locate, mark, and paint 2” wide playing lines using acrylic paint fortified with silica sand, as clarified by Awardee for each individual court with City Representative prior to start of work.
