The project has 4 types of partition designs to use, I am concerned about two, Partition B1 and Partition C1: Partition 1B. 2-1/2” studs spaced 24” oc with STC over 50 – there is no sound rated assembly available with STC over 50 for this stud thickness and spacing. The 2-1/2” studs have been tested with 2 layers on one side and a single layer of 5/8” on the other side, studs spacing 16” oc, not 24”, with STC 44. You would need to use 3-5/8” framing to be able to achieve STC over 50.

Partition type B1:

STC 44 is acceptable. IRS standard for STC zones are - General offices: STC 40-45 and Meeting/Conference Areas: STC 60-64. We are restrained on spacing in general offices, bumping stud size will cause issues. In any locatations where STC requirements are higher wall partition type will be modified. This will be adjusted during CD coordination.

Partition type C:

Any method is acceptable. Contractor is responsible for means and methods to meet design intent.

N/A N/A

Can you please clarify spec section 23 09 23 for direct digital controls and what type of certification is required for the installing contractor and any other information on the programming of the BAS.

The Contractor shall be an established supplier of control components with sufficient trained staff to prepare the system installation drawings/submittal, acquire the product, install the system, calibrate, program, adjust, troubleshoot and repair. The Contractor shall be adequately equipped and staffed to maintain a service organization capable of warranty maintenance. Subject to compliance with the specification requirements, provide building automation/control systems by any Factory Authorized N4 JACE Systems Integrator with Niagara N4 certified credentials.

BAS end solution shall have the ability to be programmed, expanded, and maintained by the use of only one engineering tool known as the N4 Workbench\Workplace. Split engineering tool or partial engineering tool support designs are prohibited.

Therefore VAV/FBP field level, AHU unitary level, and N4 JACE supervisory level controllers shall all have the ability to be programmed from the N4 Workbench engineering tool.
