Request for Information from Steel Foundries

The Transbay Joint Powers Authority (TJPA) issues this Request for Information (RFI) to Steel Foundries interested in participating in the production of the Cast Steel Nodes for the Structural Steel Superstructure of the Transbay Transit Center.

The Transit Center, designed by Pelli Clarke Pelli Architects, Inc., is a light-filled, open, and accessible public building. The above-ground structure, comprising the Ground Level, Second Level, Bus Deck, and Roof Park, features on its exterior a gently undulating glass wall floating above the street on architecturally exposed inclined steel columns featuring cast steel nodes at their junctions. A central structural sculpture or light column, a tubular steel construction also including cast nodes, will serve as the building’s prominent interior feature, allowing daylight from the Roof Park into the major public space at ground level.

The project requires the production of 296 steel castings made up from 71 unique geometries, totaling approximately 3.3 million pounds of cast steel. The cast steel nodes range in size, geometry, and weight, with the smallest node weighing approximately 4,400 lbs and the heaviest, 41,000 lbs. Delivery of the castings will be expected over a period commencing December 2013 and ending in December 2014. It is anticipated that the trade subcontractor for the Structural Steel Superstructure, Steel Deck, Steel Stairs and Miscellaneous Metals (TG07.1), to be selected via competitive bid in February 2013, will engage steel foundries to commence foundry engineering and casting production in March 2013.

The TJPA seeks to identify steel foundries interested in participating in the production of the castings required for this project. Interested foundries should complete the questionnaire included in Attachment 1 of this RFI, indicating their production capabilities with reference to the various castings required for the project and providing information on their available production capacity for this project. Cast Connex, the TJPA’s engineering and administrative services consultant for the cast steel nodes, will process and communicate the information to the TG07.1 bidders; bidders will then follow up with the foundries of their choosing to negotiate pricing and delivery terms for the castings. Ultimately, the single successful bidder will contract with the foundries of its choosing to produce the steel castings required for this project.

Please forward responses to the questionnaire to Cast Connex Corporation via email at info@castconnex.com, with the subject line heading: TRANSBAY – Response to Foundry RFI, by October 1, 2012.
