Q14. Note 4.022 /AD-101 calls for demo of intermediate concrete cap above complete – see structural. Please clarify, as this does not appear on structural.

Refer to detail 9/S-521 for Concrete Cap/Slab demolition at connection point of East wall.

Q15. Note 4.011 / AD101 calls for demo of former infill. Please clarify that this was infilled with CMU or metal studs and EIFS.

Construction is assumed to be consistent with the adjacent construction with metal stud infill, yet with an EIFS exterior face.

Q16. General Note 5 on AD-101 states that typical wall construction to be demolished is metal stud and gyp. board that extends to the existing structure. Due to no access to identify exiting conditions we cannot determine which existing walls are metal stud and drywall or masonry. Please clarify any locations of existing walls that are not metal studs and gyp.

As the note states all existing construction is considered metal stud and gyp, unless noted otherwise. In the specific demolition notes, for instance 4.014, it notes where CMU construction and demolition occur. For specific clarification, the two rooms constructed of CMU/Concrete construction are the future 123/125/126/130 shell space, and the area supporting and surrounding the concrete cap demolition at note 4.022.

Q17. Note 4.026 on AD-101 calls for salvage and reinstall of markerboards. This note appears twice and does not clarify location within rooms. Please confirm that there are only 2 marker boards that need to be removed and salvaged.

Marker boards are located on the plan north and west walls of each respective briefing room (four (4) boards in total).

Q18. For purposes of accurately bidding the demolition please provide as-builts of existing building.

As-Builts were used to develop the plans provided within the solicitation. The A-E that developed the solicited plans was the A-E that performed the design and construction inspection for the previous project.

Q19. General Note 11 on sheet AD-101 calls out specification section 028213 for type, quantity and location of hazardous materials to be removed. Spec Section 028213 does not appear in the specification please confirm that there are no hazardous materials.

Q20. Detail 6 on sheet A-301 shows a metal stud wall with detail 6/A-501 called out at the parapet cap. Detail 6/A-501 is a detail for a CMU wall. Please clarify what detail is to be used at the office addition with metal stud backup at the parapet.

Detail should reference 10/A-501.

Q21. Please clarify where detail 10 on sheet A-501 is to be used.

See response to question, “Detail 6 on sheet A-301 shows a metal stud wall with detail 6/A-501 called out at the parapet cap. Detail 6/A-501 is a detail for a CMU wall. Please clarify what detail is to be used at the office addition with metal stud backup at the parapet.”

Q22. Per spec section 05 12 00 Structural Steel, paragraph 1.3 AISC Quality Certification is required for the structural steel fabricator. Due to the small size of this project this qualification severely limits the number of AISC steel fabricators that are interested in bidding this project. Please consider removing the AISC Quality Certification for the structural steel fabricators.

We would like to maintain this requirement.

Q23. Per spec section 05 12 00 Structural Steel, paragraph 1.3 AISC Quality Certification is required for the structural steel erector. Due to the small size of this project this qualification severely limits the number of AISC steel erectors that are interested in bidding this project. Please consider removing the AISC Quality Certification for the structural steel erectors.

Current penetrations have been certified to meet the requirements and may remain as installed. Above ceiling retrofitting work for improved inspect-ability is part of this work, but not under the purview of FP and their penetrations.

Q27. Specification 23 05 93 Testing, Adjusting, and Balancing for HVAC do not indicate whether the entire building's HVAC must be Tested, Adjusted, and Balanced or only if renovated and addition areas must be. Please confirm.

If a system does not serve a portion of the building being modified or added as part of this project, it does not have to be done for that system.

Q28.
