60. Who is responsible for the utility locations?

No below ground utility locates are expected on this contract.

61. Due to current potentially significant tariffs being placed on the importation of building materials such as wood or steel by the current Presidential Executive Branch, if a tariff is placed after bid time and before award will the government consider a price escalation on a contract value for products such as steel or wood should the executive branch levee tariffs effecting such materials? Most of these materials would still have been Buy American compliant as the tariffs would increase pricing on all steel or wood materials, regardless of origin.

In accordance with FAR 52.229-3, if a tariff is imposed after bid, the resulting contract amount may be increased by the amount of any after-imposed Federal tax if the Contractor certifies in writing that no amount for such newly imposed Federal excise tax or duty or rate increase was included in the contract price, as a contingency reserve or otherwise. Adversely, the contract amount may be decreased by the amount of any after-relieved tax.

62. Describe all tasks that may be required for this project as it relates to infectious control?

Enterprise server to be integrated to is Niagara AX. Existing individual controllers are Schneider as well as other legacy protocols and manufacturers.

67. Drawing M507, detail 1, as defined, the existing communication network include the existing conduit and cabling?

Detail 1 is diagrammatic as a typical control architecture and does not show entire controls network as-built architecture. All new controllers will require their own conduit and cabling and shall be integrated to the existing Niagara AX enterprise server.

68. Is the existing BAS Contractor Automated Building Systems(ABS) located in Tulsa OK? YES. If so, the specifications indicate that ABS are to perform the final tie from the new into the existing BAS and that ABS is to provide the prime contractor the pricing directly and not through the mechanical contractors, is this correct?

See Specification 23 09 23 1.4.A.1

QUALITY ASSURANCE

A. Criteria:

1. Single Source Responsibility of subcontractor: The Contractor shall obtain hardware and software supplied under this Section and delegate the responsibility to a single source controls installation subcontractor. The controls subcontractor shall be responsible for the complete design, installation [and commissioning] of the system. The controls subcontractor shall be in the business of design, installation and service of such building automation control systems similar in size and complexity.

69. Is ABS required to provide pricing and detailed scope of work to all Bidding contractors?

Contractor shall determine how to develop proposal

70. Can a detailed scope of work from the BAS / Control contractor be provided in an amendment form the VA?

71. Trending is important to verifying system operation – page 132 of the specification. Will the BAS Contractor add this to their point list before balancing and testing?

Systems shall be commissioned to verify trending following Test & Balance and control point integrations.

72. Can the clarify the fire alarm system interlock. The specs call for tying into the smoke system with the smoke detector on the AHU. Is this the only interlock?

Typical AHU start interlocks include smoke detectors, freeze stat, fire damper position, high static pressure, low static pressure, etc.

73. Can the discuss the responsibility of the BAS contractors during commissioning?

See Specifications 01 91 00 General Commissioning Requirements and 23 08 00 Commissioning of HVAC Systems

74. Can the mechanical contractor purchase the AHU’s and VAV’s with controllers factory installed provide they are Bacnet?

This would need to be coordinated with the controls subcontractor. See Question #3 above.

75. On Page 50, the network architecture has been defined. Under the Control System Configuration, it basically says to use the existing ECC(Siemens), Install new bacnet controls but they call the model number out as a Siemens part number, please clarify?

Disregard Siemens nomenclature. See question #2 above.

76. Is this Project a taxable project?

See Tax Exemption form attached

77. Question: Several rooms require lowering of the ceiling height to accommodate the HVAC Equipment. Can the VA provide a typical architectural detail for how to handle the window framing?

Reply: An exact detail could not be located but the attached picture represents how we would like to see the drop ceiling installed where the ceiling is below the top of the window.

78. Question: The Fan Schedule for 1-SF-1.1 lists 20,000 CFM. The AHU Schedule for 1-AHU-1.1 lists 13,000 CFM. Which one is correct?

Reply: Modify Fan Schedule on Drawing M-607 so the Air Flow for 1-SF-1-1 is 13,000 CFM [6,100 L/s].

79. Question: On sheet EP101 Note 1 & 2 say to connect the New Exhaust Fan to the New VFD and the VFD to the existing power source. The fan is above the ceiling in a corridor, where will the New VFD be located? Same question on Sheets EP102-EP105.

Reply: The existing fan motors, controllers/VFDs, and circuit conductors are above the ceiling tiles. Please see below:

Existing fans and ducts with existing motors and VFDs above ceiling:

Fan motor above the ceiling tile:

Motor controller/VFD above ceiling tile:

They will need to remove the existing controller/VFD and replace with the new equipment, in the same location as previous installation, utilizing the same power connection, above the ceiling tile.

80. Question: Sheet E-501 Detail 2 Lighting Control Diagram. Can the engineer provide a Manufacture and part numbers for this design?

Reply: The following is the “basis of design” and does not constitute a specification of manufacturer. That is to say, we will approve alternate manufacturer’s products with similar functionality.

Vacancy Sensor:

Wattstopper LMDC-100

Lighting Control Device:

Wattstopper LMRC-211

Low-Voltage Dimmer Switch:

Wattstopper LMDM-101

The Wattstopper system requires 0-10V dimming wiring be installed between the Lighting Control Device and the luminaires, as well as Cat-5 cable between each sensor / dimmer-switch and the Lighting Control Device (can be daisy-chained).

87. Question: In the electrical drawings in multiple locations it says to connect the new equipment to the control system. Is this something ABS will be handling? What will be required of us? Do they need any conduit ran for this?

Reply: The new equipment (VFDs, etc.) will need to be connected to the existing building mechanical controls. This needs to be coordinated with the mechanical controls contractor, they may require conduit; however, in cases where replacing existing equipment, I would think that conduit to a control point must exist for the existing equipment to function.

82. Question: How much of this work do you anticipate being after hours or on the weekend?

Reply: The Sheet Notes indicate that “WORK SHALL PRIMARILY TAKE PLACE AFTER BUSINESS HOURS AND SCHEDULE WEEKEND PERIODS.” This is a functioning hospital, I would expect that 90% or more will occur in those allotted times; however, coordination with the COR is required.

83. Question: On 1-AHU-2 Steam Heating Coil (1-SHC-2-1)

a. The scheduled Steam Heating Coil is Noted as being a Face and Bypass Coil, however the scheduled Face velocity is scheduled at 314.5 FPM, which is close to the Face Velocity of this units Chilled Water Coil. Is this coil truly a Face and Bypass coil?

Reply: This coil is to be a face and bypass coil. The listed velocity is a cross the coil assembly, assuming it is similar to the cooling coil in overall size.

b. The scheduled Steam Heating coil EAT is 31F and the LAT is 55 F. The requested Total Capacity is 166 MBH, which will result in a LAT of 97.5 F. Which one is correct?

Reply: The capacity is to be 166 MBH since this is a 100% outside air unit. Change the entering air temperature to -9 Degrees F. (-23 degrees C.) And extra capacity is to provide a safety factor.

c. The Drawing on the plans scales off to be approximately 280” in length, whereas the existing equipment is 103” in length. Are the equipment in the drawings to scale?

Reply: The equipment drawing are to scale for the design basis unit. Since there are no obstructions in that area, the size of the new unit is not limited in length, but the width is restricted to be able to provide better service clearances than the existing unit.

2. On 1-AHU-3

a. All Schedules show an airflow of 2600 CFM, Except for the Chilled Water Coil Schedule which shows an airflow of 3000 CFM. Which is correct?

Reply: The airflow is 2600 CFM (1200 L/s). Please change the Chilled Water Cooling Coil Schedule and the Hot Water Heating Coil Schedules to match this value.
