This is Addendum No. 2 to the bidding documents for the Wissahickon Valley Public Library's Blue Bell Branch Library Renovation project located in Pennsylvania. The addendum, issued on September 11, 2026, modifies and supplements the original contract documents dated August 21, 2026. The project scope includes general construction work encompassing demolition and reconstruction of interior partitions and finishes, construction of a new entrance feature, and selected additions of doors and windows. Sealed proposals must be submitted through PennBid by 10:00 A.M. on Thursday, September 15, 2026. The last day for submitting written technical and scope-related questions is Friday, September 11, 2026. Electronic copies of drawings and specifications became available on Tuesday, August 25, 2026 via PennBid. All bidders are required to acknowledge receipt of this addendum on their proposal forms and in accordance with the Advertisement for Bids and Instructions to Bidders, with failure to acknowledge all addenda potentially resulting in disqualification.

The addendum specifically addresses changes to drawings, including the provision of partial elevations of the after-hours entrance on drawing A-201. Each bidder must submit one copy of the proposal as prescribed, accompanied by a bid guaranty as specified in the Instruction to Bidders (Exhibit C). Performance and Labor and Materials Bonds in the amount of 100 percent of the contract value are required, along with a Maintenance Bond in the amount of 25 percent. Bidders should direct all questions and obtain all project documents through PennBid rather than contacting the Wissahickon Valley Public Library directly. The proposal process will be administered by PennBid, with notification of bidders following the standard PennBid procedures.
