Recommendation to Solicit Bids to Repair the Water Infiltration Leak at the Aurora Police Department Headquarters and repair pitched walkway on second deck of structure.
body
PURPOSE:
Currently there is water leaking in the bathroom at booking at the Police Headquarters. The purpose is to go out to bid to isolate and repair the water leak. In addition, the current walkway on the second deck has water pooling. The purpose is to go out to bid to repair the issue.
BACKGROUND:
There is evidence of water leaking into the booking bathroom. The prior superintendent caulked the wall in hopes of curing the problem. The fix has failed and the leak has returned after 2 years. In addition, the current walkway on the second deck of the building is pitched towards the building creating water to pool and puddle up.
DISCUSSION:
In order to seek out the permanent fix, we did exploratory work that included removing the cap stones to expose the waterproof membrane in order to identify the permanent fix. We will remove and replace insulation and drainage mat as required and install new flashing and tie into existing waterproofing membrane. We will extend stainless steel flashing to exterior wall and tie it to base flashing. The new 24 gauge stainless steel flashing will be solder at the edges as required to form a continuous flashing. We will grout the CMU cell solid. In addition, we need to remove concrete topping from the second deck walkway. Pour concrete to existing trough and add an additional roof drain with vandal-proof secure top and polished nickel bronze top.
IMPACT STATEMENT:
We anticipate spending up to $120,000 for this work, the funds are available in account 340-1710-417-38-05 for this project, and there will be no impact to other departments or divisions.
RECOMMENDATIONS:
Finance Committee approval to solicit bids for Water Infiltration Repair and repair of second deck walkway, for the Division of Central Services.
