31. Mary Ave Footbridge remaining funds & quail sculputureCUPERTINO DEPARTMENT OF PUBLIC WORKS SU UVIARY AGENDA ITEM 3 _ AGENDA DATE April 6, 2010 SUBJECT AND ISSUE Mary Avenue Bicycle Footbridge Project Review of the remaining project funds and the closeout work for the Mary Avenue Bicycle Footbridge project. 2. Report on the theft of the Quail sculpture from the Mary Avenue Bicycle Footbridge entry plaza and the feasibility of installing a security camera system to protect the artwork from future vandalism. REMAINING PROJECT FUNDS AND THE CLOSEOUT WORK On November 20, 2007 Council authorized and ,warded the $7,469,735 construction contract for the Mary Avenue Bicycle Footbridge to Golden State Bridge and authorized the Director of Public Works to expend $1,000,000 in construction contingency. On April 30, 2009, the bicycle footbridge was opened to the public in a celebration ceremony held at the entry plaza in Cupertino. On May 25, 2009, Final Completion of the Golden State Bridge contract, reflecting all of the construction, was achieved by the general contractor. Final Acceptance, formal action taken by Council when all of the construction related items were complete, was authorized by Council on September 15, 2009. This action allowed the release of retention and initiated the process of releasing bonds. The project was then recorded in the Santa Clara County Recorder's office. To date, the City has released all but 10% of the Faithful Performance Bond, which will be released on September 15, 2010, in accordance with City policy. 31 -1 ANALYSIS It is common for a project of this magnitude, involving outside agencies, to have a number of closeout issues requiring substantial time to resolve before the project can be declared complete. A project such as this may require as much as two years finishing the remaining items of work to close it out. The project is expected to be fully complete and closed out with VTA, Caltrans, the Water District, PG &E, AT &T, the design team, and the general contractor, between September 2010 and December, 2010. Caltrans provided oversight of the project and the City constructed the bridge in accordance with Caltrans criteria and standards covered by a formal Cooperative Agreement. The City is obligated by that agreement to provide, among other things, As -Built drawings, project completion documents, land transfer documents, and project related material. The collection, organization and distribution of that information is currently underway. The following are the close -out items (including the Caltrans matters) to be accomplished by the end of 2010.

Balance Remaining in Project $ 110,000 Set -aside for closeout 35,000 Balance $ 75,000 The balance of $75,000 has been proposed to complete the re- installation of the Quail sculptures and the security camera system as discussed below and as shown in Attachment A to this report MARY AVENUE BICYCLE FOOTBRIDGE ENTRY PLAZA QUAIL SCULPTURES AND SECURITY CAMERA SYSTEM The Mary Avenue Bicycle Footbridge was opened to the public on April 30, 2009 in a celebration ceremony held at the entry plaza at the southern end of the bridge in Cupertino. The entry plaza design included seven slightly oversized bronze Quail and a bronze Red Tailed Hawk. The hawk was mounted on a pole overlooking the plaza and the Quail were mounted on two large granite boulders in the center of the plaza within easy reach of the public. 31 -2 Several weeks after the opening, one of the smaller Quail was discovered to have been stolen from the site, with just the feet and legs left still attached to the boulder. The Quail appeared to have been broken off its legs by a significant impact, which left the legs still anchored to the boulder with the original stainless steel anchor rods and epoxy adhesive. City staff removed the broken legs and began to seek evidence from the local residents and the bridge users about the vandalism that might lead to the return of the Quail. Unfortunately, the Quail was never recovered. Within two weeks, a second Quail was stolen in a similar manner, and out of concern for further loss, all of the Quail were removed from the boLdders. A local resident, adjacent to the plaza, did report hearing a large impact sound similar to it ball bat hitting a metal surface one day around noon time, near the date -of the second Quail theft. The second Quail has also not been recovered. The artist's concept for the bronze sculptures was to present a representation of native birds that are common and appealing to many people. The Quail were intended to be within easy access of young children and were specifically designed to withstand the typical forces children and adults might exert on them. The design of the legs and feet were naturally of special concern. The original bronze legs were designed to be strong enough to resist any of the imagined forces that young children and adults might exert on the birds, however, it was not expected that the Quail would be attacked in a vicious manner with the intent of destruction. Following the removal of the Quail, staff contacted the artist, sculptor and the foundry to discuss ways to improve on the strength of the legs. The sculptor and the foundry owner all agreed that the legs of the remaining birds could be reconstructed with large diameter stainless steel rods and anchored inside the bird's body. The stainless steel could then be tinted to match the bronze color of the body. The sculptor agreed to make a new mold and the foundry agreed to recast the two missing Quail and to repair the other Quail, at no cost to the City. Once this reconstruction was accomplished, each of the birds was placed in a heavy vise and several people at the foundry attempted to bend or break the birds from their legs in a variety of ways. The new legs held up perfectly without showing any evidence of the forces applied to them. The reconstructed bronze Quail are currently waiting to be reinstalled on the granite boulders or in some other suitable location. Following the theft of the Quail, a numb(!r of trail and bridge users expressed deep disappointment in the vandalism and encourages[ the City to consider installing a security camera system at the plaza. ANALYSIS The surveillance system proposed a dual camera security system, that captured frontal images from either side° of the plaza. The cameras, to be effective, have to be capable of capturing images in the variable light conditions of both nighttime and daytime. The images also need to be stored on a secure file server and the most reasonable location is the Municipal Service Center IT room. 31 -3 The images need to be sent to the file server and unfortunately, the remote location of the site, although quite close to the Service Center, makes it necessary to send the images using wireless microwave technology. All of these unique conditions contribute to the budgetary cost estimate of a suitable system. The most recent cost information indicates that a suitable dual camera security system will cost- approximately $75,000. A more detailed description of the surveillance system is- described in Exhibit A. There are, of course, other alternatives to' the expenditure of these funds, including, simply reinstalling the Quail and risking another theft but trusting to the strengthening of the legs as sufficient to deter future theft and/or vandalism. Another alternative would be to not reinstall the Quail family at all by the bridge but to install them in a more protected location. Each of these alternatives, as shown in the attached Exhibit A for the Council's consideration, have cost implications, but are much less costly than the surveillance system. FISCAL IMPACT The Council may wish to defer action of the Quail alternatives for consideration during the 2010- 2011 Capital Improvement Program. However, a key fiscal impact is that any funds remaining after complete project closeout must be equally shared with the Valley Transportation Agency (VTA), the major source of funding for this project. For example, if the Council elects to proceed with the least cost alternative (i.e., installing the reinforced Quail in their original location for $5,000) the balance remaining would be $70,000. By agreement, $35,000 of that amount would be refunded to the VTA for other bicycle programs in the county. STAFF RECOMMENDATION Staff recommends that Council preserve the remaining project funds for the necessary closeout activities. Staff will provide a more detailed explanation of the dual camera security system components during the CIP review process or at a future Council meeting should more detail be desirable.

Public Art and Security Camera Alternatives 31 -4 EXHIBIT A Mary Avenue Bicycle .Footbridge Entry Plaza Public Art and Security Camera Alternatives Following the theft of the two quail from the public art display in the entry plaza in early summer of 2009, staff began investigating; the feasibility of installing a digital video security system for the entry plaza. The system, as currently envisioned, includes the major components listed below: • Weatherproof power cabinet with pad at Entry Plaza • Conduit for power and image transmission • Two poles, each with a digital camera • Microwave transmission dish mounted on one of the camera poles • Microwave receiving dish mounted on top of the Service Center • File server and digital recording and storage devices in Service Center The system, as currently envisioned, would provide the ability to capture and retain images for a short period or up to 30 days on a file server in conjunction with a recording device. Suitable cameras have been identified that have high resolution and contrast control to enable positive identification during both day and night light levels. It is thought that the most cost effective way to transmit the images to the file server is by use of low frequency wireless microwave technology. The cost estimates below are provided to assist in the development of a project budget for the work described. The budgets include anticipated administrative and project management costs in addition to the costs for equipment, material and labor. ALTERNATIVE A $5,000 Install the reconstructed quail on the boulders in the entry plaza and trust that the rebuilt legs are sufficiently strong enough to prevent their theft. ALTERNATIVE B $15,000 Do not reinstall the quail at the entry plaza but plug the old anchor holes and repair the boulders. Display the reconstructed quail in City Hall or another protected indoor public location. (cost may vary depending on the location selected by Council) ALTERNATIVE C $75,000 Design and construct a security camera system at the entry plaza to provide the capturing and storing of digital video images sufficiently detailed enough to aid in the arrest and prosecution for criminal behavior in that area and reinstall the quail on the boulders after verification that the camera system works properly. 31 -5
