Approve Actions Relative to the Amendments to the Interagency Agreement with the State of California, Division of Mines and Geology to Install a Seismic Instrumentation System on the Golden Gate Bridge Relative to Contract No. 99-B-5, Golden Gate Bridge Seismic Retrofit (Phase II), South Approach Structures; and, to Install a Wind Monitoring System on the Golden Gate Bridge

In a report to Committee, Deputy District Engineer Ewa Bauer, District Engineer Denis Mulligan and General Manager Celia Kupersmith provided staff’s recommendation to approve actions relative to amendments to the Interagency Agreement with the State of California, Division of Mines and Geology, Strong Motion Instrumentation Program (SMIP). The report provided background regarding the District’s Golden Gate Bridge Earthquake Response Plan, which was adopted by the Board of Directors in October 1996, and includes the provision of the Golden Gate Bridge Seismic Instrumentation System connected to the Sacramento office of SMIP.

The report stated that the Board of Directors, by Resolution No. 92-26 at its meeting of February 14, 1992, approved the formation of the Golden Gate Bridge Seismic Instrumentation Advisory Panel (Seismic Advisory Panel), composed of eminently renowned experts in the field, to plan and design the seismic instrumentation system. The report also stated that the Board of Directors, by Resolution No. 92-194 at its meeting of September 11, 1992, authorized execution of an Interagency Agreement with the SMIP for the procurement and installation of the Phase I Seismic Instrumentation System for the Golden Gate Bridge, consisting of 76 sensors and two recording stations distributed over the entire structure as well as in close proximity of the structure.

The report further stated that the Board of Directors, by Resolution No. 2001-121 at its meeting of July 13, 2001, authorized execution of an Interagency Agreement with the SMIP for the Phase II Seismic Instrumentation System, consisting of 25 sensors for the Golden Gate Bridge South Approach Structures, 24 sensors for the North Viaduct and North Anchorage Housing and two recording stations at Pylon S1 and the North Anchorage, to be installed in stages as part of the Contract No. 99-B-5, Golden Gate Bridge Seismic Retrofit (Phase II), South Approach Structures. Due to the extension of the Contract No. 99-B-5 contract time and to a recent assessment of the Phase II Seismic Instrumentation System, it has been determined that additional free field sensors and rehabilitation of the downhole sensors should be added to the scope of work by the SMIP. The Seismic Advisory Panel met and, at its meeting of October 25, 2006, recommended installing a wind monitoring system on the Golden Gate Bridge to monitor the Bridge response and to provide a warning system to assist in implementing traffic control measures during wind storms and to assist Bridge inspection subsequent to wind storms.

The report noted that the SMIP has submitted a cost proposal in the amount of $35,000 for the additional work for the Phase II Seismic Instrumentation System and a cost proposal in the amount of $20,000 for installation of the wind monitoring system. Staff has determined that these cost proposals are commensurate with the scope of work and that a budget increase and a budget transfer are necessary in order to carry out these amendments. It is recommended that amendments be executed with SMIP for the Phase II Seismic Instrumentation System and for the wind monitoring system. A copy of the report is available from the Office of the District Secretary and on the District’s web site.

At the meeting, Mr. Mulligan summarized the staff report, stating that the wind instrumentation will be connected to the seismic instrumentation transmission cables and will capture data from the sensors that were previously installed as part of the Seismic Instrumentation Project.

Discussion ensued, including the following:

  • Director Reilly made the following comments and inquiries:
    • She inquired as to whether the technology for the Seismic Instrumentation System is kept current. In response, Mr. Mulligan stated that the sensors and recording stations use state-of-the-art technology, and that the instrumentation system is upgraded when new technology becomes available.
    • She inquired as to the location of the sensors for the Seismic Instrumentation System. In response, Mr. Mulligan described the various locations of the sensors, noting that some sensors are distributed over the entire Bridge structure and that other sensors are located underground near the Bridge in close proximity of the structure, some as deep as 500 feet below the surface.
  • Director Grosboll inquired as to the life expectancy of the sensors. In response, Mr. Mulligan stated that the acceleration sensors can last over 10 years, while the data recorders, since they are computer-based, have a shorter life span. Mr. Mulligan further stated that advancements in sensor technology can precede the life expectancy of this equipment.

Staff recommended and the Committee concurred by motion made and seconded by Directors STROEH/MARTINI to forward the following recommendation to the Board of Directors for its consideration:

RECOMMENDATION

The Building and Operating Committee recommends that the Board of Directors approve the following actions relative to the amendments to the Interagency Agreement with the State of California, Division of Mines and Geology, Strong Motion Instrumentation Program (SMIP):

Approve Actions Relative to Contract No. 2007-B-2, Merchant Road Improvements and Realignment, with Granite Rock Company, dba Pavex Construction Division

In a report to Committee, Deputy District Engineer Ewa Bauer, District Engineer Denis Mulligan and General Manager Celia Kupersmith provided staff’s recommendation to approve actions relative to Contract No. 2007-B-2, Merchant Road Improvements and Realignment. The report stated that the Board of Directors, by Resolution No. 2006-053 at its meeting of June 23, 2006, authorized award of Contract No. 2007-B-2, Merchant Road Improvements and Realignment, to Granite Rock Company, dba Pavex Construction Division (Pavex), in the amount of $1,318,861, and authorized a contingency fund in the amount of 131,886, equal to 10% of the total bid price.

The report described the background of the Merchant Road project, which was jointly funded by the District and the Presidio Trust The report also stated that the improvements and realignment of Merchant Road are complete, and a compilation of the actual quantities furnished and installed for contract items “Asphalt Concrete” and “Minor Concrete (Curb, Gutter, Sidewalk and Driveways)” exceeded the estimated quantities used to obtain bids for Contract No. 2007-B-2 by 151 tons and 22 cubic yards, respectively.

The report also stated that it is recommended that Change Order No. 13, in the amount of $30,910, be executed, to compensate Pavex for the additional 151 tons of asphalt concrete installed at the “Contract Unit Price” of $110 per ton and for the additional 22 cubic yards of minor concrete installed at the “Contract Unit Price” of $650 per cubic yard. In addition, since the cost of Change Order No. 13 will deplete the 10% contingency fund, it is further recommended that the contingency fund be increased in order to compensate Pavex. A copy of the report is available from the Office of the District Secretary and on the District’s web site.


At the meeting, Denis Mulligan summarized the staff report and described the other change orders that were issued for Contract No. 2007-B-2, noting that many of these change orders were associated with unanticipated man-made buried objects that were discovered during the course of work to excavate materials in order to construct the new section of roadway. In addition, a live gas line and water lines were discovered in locations that had not been clearly identified on historic Presidio maps used to create the contract plans.

Discussion ensued, including the following:

  • Director Grosboll inquired as to whether 13 change orders was an unusually high number of change orders for a construction contract of this type. In response, Mr. Mulligan stated that the amount of change orders was not unusual, given the historic nature of the Merchant Road project area, and given the fact that the project was jointly funded by the District and the Presidio Trust.
  • Director Middlebrook inquired as to whether the gas line discovered during construction supplied gas to the Golden Gate Bridge Toll Plaza facilities, and Mr. Mulligan answered in the affirmative.

Staff recommended and the Committee concurred by motion made and seconded by Directors STROEH/MARTINI to forward the following recommendation to the Board of Directors for its consideration:

RECOMMENDATION
