PURPOSE

Staff requests City Council approval of the As-Built Record Drawings for traffic signal improvements at nine intersections as a part of Bid Schedule No. 1123.  The project was completed on October 8, 2003, and the as-built drawings were reviewed and approved by staff on February 18, 2004.

BACKGROUND

City Council approved contract documents for Bid Schedule No. 1123 on October 22, 2002 for the construction of left turn traffic signals at ten intersections in Burbank.  Those locations are:

1. Alameda Avenue and San Fernando Road

2. Alameda Avenue and Glenoaks Boulevard

3. Buena Vista Street and Olive Avenue

4. Glenoaks Boulevard and Olive Avenue

5. Magnolia Boulevard and Buena Vista Street

6. Hollywood Way and Burbank Boulevard

7. Burbank Boulevard and Buena Vista Street

8. Victory Boulevard and Magnolia Avenue

9. Victory Boulevard and Olive Avenue

10. Riverside Drive and Buena Vista Street

The project began on December 6, 2002, and construction was completed on May 15, 2003.  The Notice of Completion was dated October 8, 2003.

ANALYSIS

This project constructed left turn traffic signal phasing at nine locations.  The tenth location, Riverside Drive and Buena Vista Street, was not constructed because Caltrans would not agree to the signal modification.  The existing level of left turning traffic and the intersection accident experience does not currently meet Caltrans minimum criteria for the installation of separate left turn phasing.

During the construction period, small changes were made in the design at some locations because of unforeseen conditions found during the construction or because of changes in left turn signal operation.  The change from protected left turn phasing to protected-permissive left turn phasing at a number of locations was one change that required some hardware modifications.

At the completion of construction, the initial design plans were changed to reflect the �as-built� modifications that were included during construction.  These As-Built Record Drawings show the actual equipment used, the location of hardware and actual signal operation in place at each location.

RECOMMENDATION

Staff recommends that City Council approve the As-Built Record Drawings of Bid Schedule No. 1123 as a true and complete record of the facilities in place at each of the nine intersections.  City Council approval of the Record Drawings will insure that the City is protected by design immunity for any future issues that may arise.
