10. Statement of work: “The Contractor shall provide testing, balance, and adjustment (TAB) of ALL HVAC systems for each building by third party (with documentation) to include new and existing equipment. controls contractor to support TAB as required.”

Is Pre-Tab required to obtain current readings, prior to system swap out? Are the original design flows available to reset the tab parameters to? This project does not include replacement of mechanical equipment, which may impede the ability to properly set TAB parameters.

A. Only some of the buildings have existing as-built drawings that show the Pre-Tab. These will be provided after award at the pre-construction meeting. Buildings that will require mechanical repairs will be handled on a case-by-case basis through RFIs during contract performance.

11. Access to buildings: With a significant number of these buildings being TLF or high security areas, we will need access to multiple adjacent areas in order to complete the communication path and meet the performance period timeline. Can it be assumed that we will have access to areas conveyed on project schedule, which may be large swaths of TLF rooms (A floor at a time)? There are approximately 262 guest rooms in TLF locations and 280 days to complete the entire scope A. The on-site contractor project superintendent will coordinate with the construction manager for any high security areas or TLF rooms to ensure there is unimpeded access to all areas required for contract performance.

12. Attachment 5. MAHG211140 Specifications V2, Section 23 81 00, Page 4 "The Building Management System Contractor shall be the primary manufacturer- owned branch office that is regularly engaged in the engineering, programming, installation and service of total integrated Building Management Systems.”

As a small business, we are not branch owned, we are a partner. Is there a way to edit this language?

A. The Building Management System Contractor shall be able to provide the engineering, installation, programming, and service of a turn key complete and operational integrated Building Management System that is compatible with the current user operating systems Metasys or Desigo (Apogee).

13. Attachment 5. MAHG211140 Specifications V2, Section 23 81 00, Page 5 "The BMS Contractor shall be a recognized national manufacturer, installer and service provider of BMS."

How does this apply to partners, not manufacturers?

A. The BMS contractor shall be a known installer and service provider of BMS BACnet capable control systems.

14. Attachment 5. MAHG211140 Specifications V2, Section 23 81 00, Page 5 "If a franchised dealer is to be considered via addendum, the authorized building control system installer must provide a letter written by a minimum Vice President of Operations for Johnson Controls. This letter must be provided to the engineer along with the other supporting documentation at the time of request for equivalence."

Can this language please be removed as it eliminates all competition other than Johnson Controls as a sole source provider and hinders competition?

A. If a franchised dealer is to be considered via addendum, the authorized building control system installer must provide a letter written by a minimum Vice President of Operations of the (franchised dealer). This letter must be provided to the engineer along with the other supporting documentation at the time of request for equivalence

15. Attachment 5. MAHG211140 Specifications V2, Section 23 81 00, Page 5 "As evidence and assurance of the contractor’s ability to support the Owner's system with service and parts, the contractor must have been in the BMS business for at least the last ten (10) years and have successfully completed total projects of at least 10 times the value of this contract in each of the preceding 5 years."

As a total small business set aside, how are we to clear this hurdle?

A. As evidence and assurance of the contractor’s ability to support the Owner's system with service and parts, the contractor must have been in the BMS business for at least the last five (5) years and have successfully completed total projects of at least the value of this contract in each of the preceding 5 years.
