As stated in the SOW the contractor is responsible for verifying all dimensions and creating shop drawings to fit. Question 2. Do the windows need to match the wall specs concerning pressure? Answer: Yes, the windows need to meet the specifications concerning pressure. If the walls exceed the specifications the windows do not need to be the same. As a clarification on the Lab Positive Pressure: The Lab shall be able to withstand the structural forces of a positive pressure of 0.2 inches of water (0.0072 psig). Question 3. Who is responsible for unloading materials from trucks upon delivery? Answer: As stated in SOW paragraph 3.4 "The contractor shall be responsible for delivery and in plant moving and storage of all materials. Should the government assist the contractor in any in plant moving or storage of material, the contractor shall be responsible for any damage to the materials." Question 4.

Contractors must be licensed for the use of the fork-lifts and the scissor lift and must wear proper safety equipment. Availability of the lifts is not guaranteed. EPA employees and in-house contractors have first priority for use of the lifts. Question 5. Does the ?" plywood flooring need to be fire retardant?

Question 10. Section 5.12---The support columns for the catwalk will be exposed against the existing sturcture, as the load bearing capability of the adjoining wall cannot be verified. A structural engineer may be able to sign off on this if he knows all the details of the situation. Answer: Exposed posts are not allowed. A cantilevered design may be quoted if the contractor identifies/verifies the existing build will not support the load. Question 11. Section 5.13--- Is a 22ga steel roof deck acceptable? Answer: The specification in the SOW is for a 20ga minimum. An offeror may propose other sizes, but must address how this will effect loading, flexing, and sound transmission between floors in the quotation. Question 12. Section 5.3---Is the "Ceiling" referred to actually the Top of Deck or the actual drop ceiling height? Answer: The "Ceiling" referred to in paragraph 5.3 can be considered the "Top of Deck". The requirement refers to the finished floor height of the second floor of both buildings. Question 13. Section 5.8---The maximum I-Beam width is spec'd out at 16", however a W18x35 I-Beam will be required to span 32' at 125PSF Deck loading. Section 5.2---The ceiling height may change based off the size of the beams. Answer: The PO conducted market research and feels that the 16" requirement (as stated in the Specifications) can be met. An offeror may submit an option in its quotation, for 18" beams. Question 14. What is the Top of Deck Dimension of the Existing Cat Walk? Answer: See SOW paragraph 5.2.
