BOARD MEETING DATE: |

TO: |
Honorable Board of Supervisors | ||
FROM: |
Neil R. Cullen, Director of Public Works | ||
SUBJECT: |
Renovation of Windows and Glazing - Maguire Correctional Facility, | ||
Recommendation | |||
Adopt a resolution adopting plans and specifications, determining prevailing wage scales and calling for sealed proposals for the Renovation of Windows and Glazing at the Maguire Correctional Facility (Correctional Facility). | |||
Key Facts | |||
1. |
The window frames in Building A (the original building ) of the Correctional Facility are not "water tight" which has resulted in water leaks into the building, corrosion of the metal frames and rust stains on the interior and exterior of the building. | ||
2. |
The windows in Building B (the newer section) of the Correctional Facility consist of multi layers of glass. The layers of glass are separating (delaminating), which increases the potential of the glass being broken to allow access to objects outside of the facilities, or for the broken glass to be used as a weapon. | ||
3. |
Making repairs in both Building A and Building B is expensive as it will be necessary to move the occupants to another cell within the facility while the window renovation work in a cell is being done. The Sheriff's Department has informed us that they can only release one or two cells at a time for the renovation work. | ||
Discussion | |||
A. |
Renovation of Exterior Security Windows - Building A | ||
The original Correctional Facility is constructed with pre-cast concrete panels and unitized steel window frames. A water test and the disassembly of the one of the windows indicate that water, over time, penetrated between the window assembly and precast concrete panels causing leaks into the building, stains on the exterior and interior of the building and corrosion of the metal frames. We are recommending removing the metal frames from the wall; and then removing the glazing from the frames; cleaning off all rust from the wall and frames; repainting the metal frames; reinstalling and resealing the glazing; and then reinstalling and resealing the metal frames to the structure. | |||
B. |
Replacement of Exterior Security Glazing - Building B | ||
The newer section of the Correctional Facility uses a different window configuration and has layered (laminated) security glass. It was determined that the majority of the security glazing is delaminating; possibly due to either the incompatibility of the sealant used to laminate the layers of glass, or the quality of the glass and the lamination material used. However, the glazing is no longer under warranty. The Sheriff is concerned as the security glass, when delaminated, can be broken and could be used as a weapon. We are recommending that the security glass be removed and replaced with compatible glass, laminate material and sealants. | |||
Vision Alignment | |||
We believe our recommendation is consistent with Goal Number 7, "maintain and enhance the public safety of all residents and visitors" of the Shared Vision Commitment to "ensure basic health and safety for all," as the renovation of windows and replacement of security glazing will help maintain the security of the Correctional Facility for the public, the inmates and the Sheriff's employees that operate the facility. | |||
Fiscal Impact | |||
The is the first phase of project which will repair the windows in 5 cells in the Building A and the windows on the south and east side of Building B. The Engineers estimated is $350,000, and an appropriation financed with Proposing 172 funds for this work was approved in the Capital Projects Budget in the 2002/03 fiscal year. We will recommend that additional funding be approved in subsequent fiscal years to complete the remaining 18 exterior cells/rooms and the windows on the north and west side of Building B. This work is relatively expensive since it can only be done at the rate of one or two cells at a time. | |||
There is no impact to the General Fund. | |||
A form of resolution has been approved by County Counsel. | |||
