  1. 525 Golden Gate - Phase 3
    Brook Mebrahtu, Project Manager, DPW introduced Ryan Stevens, Project Designer, KMD and Ned Kahn, Artist. He explained that the project was started in 2001 and has been stalled due to cost. The building will house 1000 PUC employees and is on track for LEED Platinum certification.?

    Mr. Stevens presented the perspectives of the structure. He explained that the southern side of the building will integrate daylight technologies including shading devices that track the sun and will roll up and disappear when necessary. The entry has an integrated interior/exterior with greenery as part of the sustainable strategy.?

    Mr. Kahn explained that the tower on the north focuses the wind into the turbines and will move the art work.  As movement occurs, each of the small panels will light up. ?

    Mr. Stevens added that the large facade will emit minimal light pollution. He presented the materials and explained that the box portion of the building is white granite with two finishes. The metal used is a warm grey aluminum that is not intended to be too light or too blue.?

    Mr. Stevens responded that it is faceted, but very slightly and will not be noticeable to most.?

    Commissioner Smith asked if there were vertical mullions.?

    Mr. Stevens replied there are not. ?

    Commissioner Smith asked about the construction and materials of Ned Kahn's artwork. ?

    Mr. Kahn replied that the pieces that move are a hinged polycarbonate. There will be a one by one horizontal beams for support. It will look like highly fragmented glass wall that is moved by the wind.  The backside is a curved glass membrane.  ?

    Mr. Mebrahtu explained that the turbines and sun will provide 8.5% of the building's energy needs. ?

    Commissioner Smith asked if the cost of the environmental measures was worth the energy savings.?

    Mr. Mebrahtu responded that since the PUC is the provider of power, it is an expression of the types of alternative power sources they use. ?

    Commissioner Haryati asked about the programming and interactivity of the ground planes.?

    Mr. Stevens replied that they are telling the story of the building and it's sustainability with the publicly accessible lobby.  They are working with a variety of people including exhibit designers. ?

    Commissioner Chow asked what the changes have been in the public realm since Phase 2.?

    Mr. Bulkley presented the landscape and explained that there has been some regrading and screening.  The existing chain link fence will be replaced by a metal picket fence.  He said that the planting includes bamboo which the gardeners reuse in other places. ?

    Mike Pierron, Architect, DPW BOA explained that the pump station is rarely going to be seen. He presented the Phase 2 and Phase 3 elevation and the continuous band around the top of the building.  The site is under the Eugene A. Doran Bridge near the Crystal Springs Dam. He explained that the basic materials are stucco and concrete.  He said that there are no skylights because of issue of debris falling from the bridge. He added that the landscaping will be all natural restoration. ?

    Commissioner Smith suggested that the entry be reduced. ?

    Mr. Pierron responded that they would like to have a formal entry to the site.  ?

    Mr. Mavroudis responded that the entire site is restricted. ?

    Commissioner Chow commented that they should keep it really simple.  The function wants to be organized and clean.?

    Commissioner Smith commented that there are some points in which the concrete walls are too close the the interior metal box.  ?

    Commissioner Smith added that the gravel should be a gravel band. ?

    Commissioner Chow added that the paving needs to be revised.  ?
