50 Will cyber security insurance be required as part of this projeCyber security insurance will not be required as a part of this project.

The specifications say that “each controller shall have a minimum of 8 inputs”, as many zone level-controlled units such as one exhaust fan or a unit heater will use far less than 8 inputs and would still have expandability, can a controller with less inputs and outputs be used?

8 inputs is the minimum required for future expandability.

52 It is assumed that splicing will not be allowed in the event wiring is to be reused, please confirm? Splicing of wire is not allowed.

Based on the age and condition of the wiring identified in the buildings is it recommended that all wiring be replaced as part of this project, Would the base like all wiring removed and replaced as part of this project?

Point to point wiring may be reused to the maximum extent possible.

54 It is assumed that all new wiring can utilize existing raceways, please confirm? Existing raceways may be reused.

The specifications say, “actuators shall provide position feedback to the controller”. Does this mean an extra set of wires or can this be calculated? And is this for major central-plant and zone level controllers (unit heater or exhaust fan)

Actuators require a hardwired feedback to determine their actual position.

56 It is assumed that, as a base standard, all wiring is required to be in conduit, please confirm? All wiring is to be in conduit.

Given that the EMCS will already be in place during construction, is a support radius of 100 miles acceptable

A support radius of 200 miles is acceptable.

The drawings reference a lot of new and existing utility meters, can you provide a list of meters that are to be reused and a list to be replaced for Electrical, Natural Gas, Water, Domestic Water, and BTU.

All meters are to be new to provide a readable pulse to the new building controller. Existing Meters may not provide a pulse output that can be digitally read.

The drawings call for a display for the electric meters, is the desire for the information to be displayed on the front end of the BMS?

The system shall display electric consumption at the Central Control system.

Submittals are to show the integrated existing control system. Are we able to get a digital usable copy of the existing submittals?

The existing control system data will be provided to the Contractor. The data is not digitally available.

In review we haven’t seen that any dampers will be replaced, can you confirm?

Dampers are not being replaced as a part of the scope of this contract. Actuators are to be replaced where necessary to provide control capability with the new system.

If, after all pre-bid questions have been answered, there is a discrepancy on the drawings between the points list and sequence of operation schematic, which one should we base our bid off of?

Default to the sequence of operations.

One of the biggest discrepancies on the drawings between the points list and sequence of operations schematic is the number of valves. We have primarily seen this on the larger equipment (AHUs, Central Plants) rather than terminal units. Can you clarify what valves are existing and if they are modulating or 2 position control?

Generally, valves are existing and only need be converted to digital control. The contractor shall verify if a specific valve is modulating or 2 position control.

64 Is the intent of the project to replace all existing valves and actuators or are we to reused the existing?

Reuse exsiting valves/actuators to the extent that they are compatible with the new controls system.

Is it correct to assume that all room temperature sensors are to be provided with a display and override capabilities except for those in common areas (hallways, cafeterias, etc) where it would be more feasible to use a flat stainless steel wall plate temperature sensor?

Acceptable as proposed.

On the drawings for many of the buildings there is a note on the points list that says, “Provide for each of 4.” Can you clarify what this note means? It is unclear whether that means there are four total units or if there are 4 points that should be combined onto one controller.

The note refers to the number of total units (for example 4 pumps)

67 For pneumatic demo, is the intent to cap it in place or remove it in its entirety? Remove pneumatic controls in their entirety.

68 Who is responsible for the pneumatic demo? The contractor is repsonsible to remove the pneumatic control systems.

The points lists on the drawings have DP sensors across all of the pumps, is the intent for these to provide pump status in lieu of a current sensing relay?

The Differential Pressure (DP) sensors will provide pump status. Current sensing relays are an acceptable alternative to DP's.

For buildings with Fin Tube Radiators, is there a valve for each of the radiators or are there cases where multiple radiators are controlled off of one valve? For reference buildings B735 and B220.

Generally, there is 1 valve per thermostat. There may be multiple fin tubes controlled by a single valve.

1. Will new electric actuators be allowed to replace old pneumatic actuators? In phase one this was not allowed, and new valves were required.

It is acceptable to replace the existing pneumatic actuators with electric digital actuators and leave the existing valve in place.

72 2. Will x-ray inspection be required on welds on HTHW lines to install BTU meters?

Third party testing of welds are not required. The contractor shall use licensed qualified welders for this project.

3. Will Testing, Adjusting, and Balancing be required, and if so, will it be required before and after required before and after

Testing, Adjusting and Balancing will be required at the completion of each building control system replacement.

74 4. Would you desire to have the new Jaces use N4 version or the existing Jace AX version?

New JACES shall have version 3.8 to be compatible with existing JACES and the central control system.

5. If an upgrade is desirable and N4 software is used on the new buildings the Web Supervisor would need to be upgraded to N4 as well. The existing system uses PxImport tags at the Jace level to import graphics to the Web Supervisor. Should an upgrade of the existing system also be included in the pricing?

The upgrade will not be performed under the scope of this contract.

6. The existing Jace 700’s would have to be individually tested to confirm that they are upgradable to N4 or they should be replaced if the test fails. Is replacement within the budget of this project since no mention of the existing system was in the scope of the project? Provide new JACES with the existing version 3.8.

77 7. Which CLIN item should be used for an N4 upgrade to the existing system if this is desired? No upgrade under this contract.

8. 2.30 OUTPUT DEVICES, VALVES AND DAMPERS.

States that all dampers and valves feedback signals are to be wired back to the control panel terminal strip. Do they need to be wired to an input of a controller?

Feedback signals for all devices shall be wired to an input of a controller.

9. The ATFP system code requirements are not listed in the References 1.1. Is the current ATFP method of implementation acceptable?

The current ATFP method of implementation shall be acceptable.

80 10. What is the temperature and pressure that the new valves on the HTHW system must be rated for? Minimum 400 deg F and 400 psi rated valves.
