BACKGROUND <br /> Fire Station No. 4, located at 1600 Oak Vista Way, was constructed in 2004, and almost <br /> immediately started showing evidence of roof leaks throughout the building. The original <br /> contractor was called back to repair roof leaks in the station on several occasions. The <br /> leaks were slowed to the point that the contractor's maintenance period was allowed to <br /> end. City maintenance crews have since made several repairs attempting to stop the <br /> water leaks. Investigation revealed the leaks are likely associated with a faulty design <br /> detail of the water proofing membrane system in the upper portion of the building's <br /> parapet walls, not a construction defect. Since all parapet walls were constructed in <br /> accordance with a faulty detail, it was recommended that the parapet wall waterproofing <br /> system be removed and replaced as it is the only effective method of stopping the roof <br /> leaks. <br /> On June 20, 2017, City Council awarded a professional services agreement to Jeff Katz <br /> Architecture (JKA) to prepare biddable construction documents to repair the Fire Station <br /> No. 4 parapet walls, as well as to perform construction support services after the bid. <br /> The project was first advertised in May 2018 as Fire Station No. 4 — Repairs to Upper <br /> Parapet Walls, CIP No. 11429. The project consisted of the repair of the roof parapet <br /> walls and painting the exterior of the building. The City opened bids May 31, 2018, with <br /> one bid received from JPB Designs, Inc. for $190,700. The engineer's estimate for the <br /> work was $125,000. During review of the bid and discussions with potential bidders, a <br /> concern was brought up about the condition of the existing roof and the potential for the <br /> roof to experience additional leaks due to the construction traffic on the roof that would <br /> be associated with repairing the parapet walls. Specifically, it appears that water has <br /> gotten under the roof membrane, likely from the leaking parapet walls. When the <br /> membrane started to heat up as summer began during the bidding period, large <br /> delaminating areas, or bubbles, began forming all over the roof. <br /> JKA reviewed the roof condition, observed several patched areas and bubbles that have <br /> formed, and agreed that the roof would not withstand the construction traffic and should <br /> be replaced. It was determined that the bid should be rejected and the project <br /> redesigned to include a full roof replacement. A letter was sent to the bidder, JBD <br /> Designs, Inc., informing them that the City was not going to proceed with the work. The <br /> first recommendation before City Council is to officially reject the bid received on May <br /> 31, 2018. <br /> JKA then modified the biddable plans and specifications to include the full replacement <br /> of the existing roof with a thermoplastic membrane roof. The project was re-advertised <br /> on June 30 and July 7, 2018 and posted on Ebidboard. During the bidding period, three <br /> non-mandatory pre-bid walkthroughs were held to allow potential bidders access to the <br /> roof. Eight contractors attended the pre-bid meetings. Pre-qualified roof installers from <br /> the roof manufacturer's online contact list were also contacted about the project. Since <br /> only bid was received on the first solicitation, staff actively sought to reach out <br /> contractors with the goal of getting multiple bids. Bids were opened on August 2, 2018. <br /> Again, only one bid was received. <br /> Page 2 of 4 <br />
