Recommended Action
RECOMMENDATION:
Staff recommends that the City Council:
1. Approve Additional Contingency in an amount not-to-exceed of $30,000 to Caltec Corporation’s contract for the Parking Structure Lot #2 Rehabilitation Project.
2. Authorize City Manager to approve additional work in an amount not-to-exceed $30,000.
Body
FISCAL IMPLICATIONS:
There are sufficient funds in the previously approved Capital Improvement Plan to fully fund this project (Attachment 1).
BACKGROUND:
Parking Structure Lot #2 is located at 222-12th Street in Manhattan Beach. This parking facility was built in 1979 and is a reinforced concrete structure with cast-in-place concrete columns. In September 2013, an assessment of the existing conditions of this parking structure was performed by Walker Restoration Consultants (Walker). The items that required attention at this parking structure include: repairs to damaged post tensioned tendons in the deck concrete slab; installation of vehicular barrier system; installation of a height restraint bar at the upper level entry to prevent large heavy load vehicles from driving on the parking structure deck; and re-striping of the parking stalls to meet current ADA Code requirements.
DISCUSSION:
On March 1, 2016, Council approved the plans and specifications for the Parking Structure Lot #2 Rehabilitation Project, authorized the City Manager to execute a contract in the amount of $630,000 with Caltec Corporation for this project, and authorized the City Manager to approve additional contingency work in an amount not-to-exceed $94,500. Construction on this parking structure began on April 4, 2016. During construction, there were many existing conditions discovered that resulted in change orders being issued to Caltec Corporation for additional work. One example is that the as-built drawings for this parking structure show the existing concrete slab on the upper deck to be 5” thick. However, when demolition began to replace the post-tensioned tendons, it was discovered that the concrete slab is only 4” thick. Because the concrete slab was thinner than anticipated, some of the rebar was laying directly on the post-tensioned tendons, and Caltec Corporation had to demolish more concrete slab then anticipated in order to remove the post-tensioned tendons.
Since the originally approved contingency amount of $94,500 was expended due to these existing conditions, an additional $30,000 in contingency for Caltec Corporation’s contract is being requested to cover these costs. Caltec Corporation proceeded with the work given that the parking structure needed to be opened to the public before the busy summer season and for large special events.
POLICY ALTERNATIVES:
No policy alternatives at this time.
PUBLIC OUTREACH/INTEREST:
Staff attended a meeting with the Downtown Business Association on January 14, 2016 and on June 9, 2016 to provide information regarding the scope of work and a schedule update for the project. This parking structure is now open to the public for their use.
ENVIRONMENTAL REVIEW
The California Environmental Quality Act (CEQA) requires public agencies to document and consider the environmental implications of their actions. Based on the scope of work, the Parking Structure Lot #2 Rehabilitation project is categorically exempt pursuant to Section 15301, Class 1(b). The project consists of the rehabilitation of the existing parking structure involving no expansion of use beyond what previously existed. A Notice of Exemption has been filed with the Los Angeles County Clerk’s office for the project.
LEGAL REVIEW
The construction contract with Caltec Corporation that was approved by Council on March 1, 2016 was executed before construction began.
