MEETING DATE: May 2, 2012
PREPARED BY: PublicWorks Director
RECOMMENDEDACTION: Approve plans and specifications and authorize advertisement for
bids for City Hall carport and Public Safety Buildingjail roof and
gutter replacement project.
BACKGROUND INFORMATION: The Public Safety Building (PSB) was constructed in 1967 and
consists of steel framing with masonry walls. The roof over the
decommissioned jail area consists of 3,016 square feet of multi -ply
built-up roof with glass felts and asphalt inter -ply bitumen surfaced with a granulated cap sheet. The
original roof was replaced in 1987, leaks significantly and can no longer be patched. The decommissioned
jail area is used for storage of office systems furniture, plumbing, electrical, painting and woodworking
supplies that are used by the Facilities Services Division staff for general building maintenance.
The City Hall carport building was also constructed in 1967 and consists of wood framing with masonry
walls. The roof over the carport consists of 2,400 square feet of multi -ply built-up roof with organic felts
and coal tar inter -ply bitumen surfaced with a river gravel embedded in floodcoat. The existing 45 -year
old roof has never been replaced, leaks significantly and can no longer be patched. The carport areas
house the Facilities Services Division's maintenance shop and offices and provides parking for three City
vehicles and three private vehicles. The life expectancy of a built-uptype roof is approximately 25 years.
Both structures have met or exceeded the useful life for its type of roofing.
After consulting with roofing contractors, staff recommends that a new thermoplastic, single -ply roofing
system be applied over the existing roof of both facilities. The single -ply roof construction is similar to
recently -installed roofs at the Police Station, Finance Department and Carnegie Forum. The estimated
construction cost of the single -ply roof over both facilities is $110,000. The life expectancy of a single -ply
roof is 25to 30 years. The contract includes a requirement for a 20 -year warranty.
To halt further damage caused by existing leaks, it is recommended Council approve plans and
specifications and authorize advertisement for bids for these two projects. The plans and specifications are
on file in the PublicWorks Department.
FISCAL IMPACT: Replacing the roofswill reduce repair costs for the interiorspaces caused
by leaking water.
FUNDING AVAILABLE: Funding for this project will be specified at the time of contract award.
