Action
Requested: Approve contract with Weatherproofing Technologies, Inc. for
Phase 3 waterproofing the exterior of Town Hall in the amount of
$111,694
Background
Information: Since the construction of the Town Hall building in 1999 very little
maintenance to the exterior of the building has taken place prior to
this initiative. Because, rain events of varying intensities have
caused water damage to interior ceilings and walls on all sides of
the building, the first phase of this project was initiated in fiscal year
2011. The leaks are primarily due to crevices that have developed
around the window frames and joints between the brick and
masonry stones. Much of the original sealant and grout has
hardened and is no longer an effective water barrier. The products
available today are superior to those used in the original
construction and should withstand exposure to the elements and
provide greater flexibility and resistance to thermal expansion.
During fiscal year 2011 and 2012, the first two phases of the
weatherproofing project addressed the north and south elevations
of the building including the steps and handrails. Phase 3 of the
waterproofing project will address the same issues on the east and
west sides of the building completing the project. In order to
complete this work, scaffolding may have to be set up on the east
and west sides of the building in order to reach many of the
problem areas which need to be addressed. The work is planned
to begin in March and will take six to eight weeks to complete.
Phase three of the project will cost $111,694. The City of
Southlake is eligible to award this project to Weatherproofing
Technologies, Inc. through the Texas Cooperative Purchasing
Network (RFP# R5101).
Financial
Considerations: Funding for this project is available from the Facilities Infrastructure
Maintenance Fund in the amount of $114,000.
Strategic Link: The award of this service contract links to the city strategy map
relative to the focus area of Infrastructure. The specific corporate
objective is investing to provide high quality public assets.

the cast stones before and after the project. The right side of the photo (south elevation) has
recently been cleaned, pressure -washed and sealed to prevent water penetration and mildew
formation. The left side of the photo (west elevation) has not been cleaned and sealed.
