Paragraph

68. QUESTION: Section 02 41 10, paragraph 3.3(C) states to provide temporary shoring. As a fully-designed project, please identify where temporary shoring will be required so all Offerors bid the same conditions.

ANSWER: Section 024119, Items removed and returned to the Owner should be turned over shortly after being removed in a “as-is” condition. Refer to specific drawing notes for such items.

70. QUESTION: In an effort to reduce cost, would the owner please consider removing the requirements for Engineering Judgements found in Section 07 84 13, paragraph 1.2(B)(1)?

ANSWER: This requirement will remain. Please note that SECTION 012100 – ALLOWANCES, Allowance No. 1 was provided to cover theses unforeseen.

71. QUESTION: In an effort to minimize costs, would the owner please consider allowing applicable trades to install firestopping as needed when their trade penetrates a fire-rated wall? Most trades are well-experienced with fire-caulking their own penetrations. Requiring specialized installers to caulk every penetration, as required by Section 07 84 13, paragraph 1.5, adds significant cost to the project.

ANSWER: It was the intent that a fire stopping contractor be utilized in lieu of each trade since there may be other wall and floor penetration that were not part of this contracted work. These other opening are required to be stopped in order to restore the existing fire rated walls and floors to the original design intent per the building department. This work is in Section 012100 – ALLOWANCES, Allowance No. 1 and needs to be part of the bid. If individual trades do their own fire stopping work there is no good way to account for the allowance.

72. QUESTION: Please confirm that the owner will provide all testing and inspections require for Section 07

84 13.

ANSWER: This is correct.

73. QUESTION: Can the owner please provide more detail on the signage requirement found in Section 07 84 13, paragraph 3.2? What type of material, size, etc., does this fire barrier sign/identification require?
