5. Detail 2/S3.04 indicates details the elevation for the elevator machine room. Please review and advise where this steel slab is being constructed, please provide a connection detail for the new masonry to the existing to remain roof structure. If the steel slab is being placed above the elevator shaft, does this elevation allow for sufficient overrun space?, and if so, what is the access to the elevator hoisting equipment and control panels.

5. Plan 2/S3.04 is partial plan of the existing machine room between lines F & G and lines 3 and 4. This area is not intended to be a machine room as part of the renovation work.

The elevation tag shown is to the existing slab that is located above the 5th floor level. No new slab is to be constructed at this location, above the 5th floor level.

6. If the contractor is to receive electronic CAD files prepared by the A/E and be required to create & maintain complete & full construction BIM Model…will the CAD files be provided in 2-D or 3-D? Or...will the provided files already be in a 3-D BIM Model format?

This will have a huge impact on the initial cost to set up the BIM Model for this project.

6. Requirement shall be removed (BIM)

7. Will electronic CAD files be provided by each of the design disciplines, i.e. Civil, Structural, Architectural, and MPE? Will the software be compatible / consistent to integrate to the BIM Model software or should we expect to utilize NAVIS for the integration?

7. Requirement shall be removed (BIM) Electronic record drawings will be required per section 01781

CO

8. In the RFP / Part IV Representations And Instructions

- Section K - Representations, Certifications and Other Statements of Offerors: there are parts that should be completed by the Contracting Officer.

8. See Section L for the Business Size and NAICS Code.

Additionally, see Paragraph 1.(b)(2) which indicates that FAR Clause 52.204-7 applies. You must therefore go to Paragraph 1.(d) page 4 of the Section K document, which directs that you go to the hyperlink to the ORCA site and complete the Online Representation and Certification Application.

9. Other than the Pre Proposal Conference scheduled for March 24th I do not see any meetings scheduled for a walk through of the facility.

Due to the number of subcontractors involved I would hope to have at least two opportunities made available.

9. See response to RFI #8 above.

10. Spec Section 01270 -- Unit Price Item # 9 asks for pricing for "additional shoring and bracing" with a unit of measurement per LINEAR METER. Specification Section 02300 does not address this"unit price" or provide a height. Since this unit of measurement is normally provided as a per square unit measure instead of linear…do you have a unit height to correspond with the linear meter length so the

10. Linear meter is correct. The shoring requirement for the work is to be included in the base bid. Unit price item #9 is intended to address the possibility that the shoring (included as par to the base bid) may need to extend deeper that expected.

contractor can properly quantify the item? Or should this item be provided per square meter?

Defective Concrete, B. Patching Mortar, C. Repairing Formed Surfaces, D. Repairing Unformed Surfaces, & E. structural repairs of concrete. Should the contractor assume the three details shown on sheet S4.11 are the only requested Unit Prices for this item?

11. The concrete repairs associated with Division 03300 are to address pouring and forming defects that may occur in newly poured concrete.

12. Spec Section 17723 - The Electrical drawings on sheet E0.02 refer to Specification Section 17723, regarding the Mass Evacuation System. Has this specification section been released yet? Where can I get a copy?

12. The specification section for the Mass Evacuation System is 16723.

13. The RFP - Section F - Deliveries of Performance, Article F.3 Time of Delivery, (a) states the delivery of the services described in Section C within 540 days.

13. The performance period is actually 365 working days which is 511 calendar days (365/(5/7)

14. Spec Section 01222 - I can find no reference to Cost Breakdown Item # CB27 on the plans. Please identify the work and location of the work in the contract document.

1. Provide as indicated and specified

17. Article B. 3 Prices -- The statement at the bottom of Table B-1 -- Schedule Of Charges For The Basic Award Period instructs the contractor to provide back-up pricing information to support each CSI Division.

Are you asking for the individual Subcontractor bid quotations for each trade we submit? When is the "back-up" documentation due? Given the MEP trades "last minute" pricing due to supply houses not releasing material quotations, it is not expected we will know which subcontractor we will use, or have a completed subcontractor proposal in time to turn in our proposal. Can we have 48 to 72 hours to review subcontractor scopes and quotes prior to this disclosure?

17. We will accept back up calculations showing how you arrive at the B.3 pricing (unit pricing and quantities). Prior to award, the selected offeror must provide the subcontractor written quotes to support the calculations.

18. Article B.3 Prices -- Table B-1 -- Schedule Of Charges For The Basic Award Period is different from Attachment 6 - Pricing Schedule. Which Pricing Schedule do you wish the contractor to submit for this proposal?

18. Please disregard Attachment #6 – Provide your individual pricing calculations to support you B.3 pricing. See #17 above.

19. Article B.3 Pricing - Are we expected to include the

Owner Contingency at $2,000,000 in the Pricing Schedule we turn in?

19. You may; however, this amount may go up or down based on the selected offeror’s award price.

20. Spec Section 02620 -- Structural Drawing S3.01 indicates that the existing subdrainage lines shall be cleaned, serviced and utilized for the renovated building. Drawing Note #2 on sheet DP2.01 states that all plumbing utilities within the building shall be removed in their entirety and replaced with new piping. Please advise which note shall take precedence.

20. The existing sub-slab drainage system is to remain and is not part of the plumbing utilities of the building although, there is a note on the plumbing and structural drawings to tie the existing sub-slab drainage system into the storm water system as part of the work.

21. Please review and confirm that it shall be the General Contractors responsibility to design, furnish and install a permanent ground water system for the sub-basement level. Please advise if there is a current system in place, and if the Engineer of record has sized the new building systems to receive additional water from the dewatering system. Also, if there is a current system in place, will you provide all of the calculations and information downstream of the proposed work? If it is a CG responsibility to design are we precluded from using the Engineer of record as the designer? Since the Engineer of record already has the baseline studies and records it should be significantly less expensive and faster to produce the design.

21. According to the existing structural drawings, there is a sub-slab drainage system below the basement level slab and the layout of this system is shown on 1/S3.01. This layout is copied from the existing structural drawings. The existing structural drawings do not indicate a sub-slab drainage system in the sub-basement level. The new sub-slab drainage system shown in the new portion of the sub-basement is to be designed by the Contractor as noted on the drawings. Using the Engineer of record could be perceived as a conflict of interest.

22. The Contract Documents indicate that there is an Opaque Film to be applied to several of the window

22. Refer to new Specification SECTION 08871 PRIVACY FILM attached openings. Please review and advise what type of film, thickness and manufacturer should be utilized.
