8. 5-24-22 6-27-22 Spec 09-6900 2.6.A Finishes: Calls for a static dissipative vinyl tile for the finish surface of the raised floor tile. This can be done, however, if using a soft vinyl surface you may not want to use more than a CC1500 tile due to weight restrictions on the vinyl (not the raised floor tile). If you decide to use a high pressure laminate (HPL) you can use a heavy duty floor tile (CC3000) and keep the manufactures warranty. Using an HPL finish surface will still meet your specs called out in 2.6.A.1.

The raised floor tiles will be High Pressure Laminate (HPL).

30. 6-3-22 6-27-22 On the Civil Drawings, multiple pages have callouts stating, “Work Performed by Others” and appear to be referencing new underground utilities. Please clarify what is meant by “Work performed by others.” Is this work to be done under a separate contract?

36. 6-14-22 6-27-22 1. On page MG0003 of the construction prints dated 10/29/2021, System Points List, Under the computer room air conditioning units, (24" and 12" wide). Is it the intent of the design team to pick up all the listed points solely through BACnet IP integration?

a. The system points list included discharge static pressure and discharge static pressure setpoint, but per the attached BACnet points obtained from Liebert, these points are not available from these units. See the attached PDF file for all available points offered through the BACnet IP interface and indicate whether something needs to be added to provide this information or if it is not critical whether this point can be omitted all together.

1. Yes. All available points from the CRAC units are to be integrated into the DDC system, as required by spec 230923-1.2-B-1.-a. The points listed on the drawings indicate a minimum expectation for this, however the actual points available from the equipment will vary depending on the manufacturer of the equipment that actually ends up being supplied for the project.

1.-a. If these points are not available for the specific units delivered during construction, they can be omitted from the integration into the DDC system. If they are available, they should be integrated along with the other available points.

37. 6-17-22 6-27-22 1. Specs Section 23 09 23 Part 1, 1.1 Project Scope.

a. Buildings 1, 2, 6 and 11 are listed but in the construction, prints Building 4 is also listed in the schedule on page MG0003, and pages 004-MD-0B1, 004-MH-0B1, and 004-MH-011. Please verify that the scope is to include Building 4.

b. Under each of the buildings - Provide new DDC sensors to monitor IT spaces.

i. Each of the air conditioning units are factory supplied with temperature and humidity sensors and integrated in the BAS system through BACnet IP.

Based on this verbiage we are planning to have independent temperature and humidity sensors directly connected to the BAS so that these could be used for alarming purposes for each IT space. Please confirm that our understanding is correct.

1. If yes, then on page 001- MH-051 IT room 5281 does not show duplicate temperature and humidity sensors should these be added?

1-a. Yes, the intent is to include Building 4 as shown on the drawings.

1-b-i. Yes, this is correct.

1-b-i-1. Yes, provide 1 set of temperature/humidity sensors (or 1 combined sensor) for this space. Locate sensor(s) on north wall of room 5281 to the right of the existing electrical panel in the NW corner of the space.

38. 6-17-22 6-27-22 On page 001-MD-0B3 in room B296, details the removal of a 12/12 Supply Duct. Please indicate new CFM values for effected VAV.

The current airflows for those units are unknown.

Part of the TAB scope for the project includes taking preliminary airflow readings for all affected spaces & units. The intent is that the modified systems would be balanced to maintain their current air flow rates.

39. 6-17-22 6-27-22 On page 001-MD-012 in room 1216, details the removal of a 12/12 Supply Duct. Please indicate new CFM values for effected VAV.

The current airflows for those units are unknown.

Part of the TAB scope for the project includes taking preliminary airflow readings for all affected spaces & units. The intent is that the modified systems would be balanced to maintain their current air flow rates. In cases where grilles are removed and not replaced, the intent would be to reduce the system airflow by the sum of airflows of removed inlets/outlets.

40. 6-17-22 6-27-22 On page 001-MD-022 in room 2306 shows an existing Liebert Unit with only temp sensor, on page 001-MH- 023 it shows the same existing Liebert Unit to have a temp and humidity sensor without keynote (1) “Provide humidity sensor and thermostat installed at 4’6” AFF.

Connect to DDC system.” Please clarify if the desired intent is to install duplicate temperature and humidity sensors used for alarming purposes as part of the scope?

The plan shows a new humidity sensor (enlarged plan 3, sheet 001-MH-023) being added but does not include the keynote. There is already a DDC temperature sensor installed on the wall in the room. The intent is to have new DDC-connected humidity sensor added at the same location.
