RE:                  1CP-206 Kaw Water Treatment Plant Building Envelope Repairs

 

Please include the following item on the consent agenda for the June 19, 2007 City Commission meeting.

 

Set Bid Date for 1CP-206  Kaw WTP Building Envelope Repairs:

 

Based on the projected timeline of this project, staff requests an opening bid date of July 17th, 2007.

 

Project History/Status : 

The Kaw Water Treatment Plant consists of two attached buildings.  The Chemical and Filter building dates from 1954, its construction includes brick facing over concrete block. The west wall of the building has numerous cracks in the exterior brick and cracks in the interior tiled corners. The wall has deflected outward. The second building is the original plant and was constructed in 1916. It does not exhibit appreciable cracking or wall deflection.  

 

February/March 2006: The Utilities Department requested proposals and received responses from five firms. We selected Walter P. Moore Engineers based on the project team qualifications and the well documented examples of similar building assessment projects.

May 2006: Walter P. Moore investigated the causes of building envelope distress and determined that leakage through building lintels has caused brick ties to erode on the 1954 Chemical and Filter building. Their inspection also found deficiencies with roofing, and concrete façade material that had exceeded its useful life.

February 2007 – Staff amended the contract with Walter P. Moore to include design of repairs related to the discovered deficiencies

June 2007 – Specifications and Bid Documents have been prepared for a proposed opening bid date of July 17th, 2007.  The project has completed the Historic Resources Review process.
