The April 15, 2017 date is earlier than the completion date than the completion date for the rest of the project. The following factors need to be considered:

- Mechanical and Electrical equipment have long lead times and have to be approved through the submittal process prior to ordering

- Support facilities such as restrooms, breakroom for employees to allow the MTC to be ready for the government to occupy

- Life safety and egress requirements for occupants

- LEED certification after a portion of the building is occupied

- Government or other contractor access to building while construction is under way

- Asphalt paving cannot be completed until late spring or summer

- Construction site is not scheduled to be completed until the end of the project

Due to these factors several items need to be clarified:

a) Is it the governments intent to occupy the MTC on April 15, 2017 or will government be doing more construction/installation activities after April 15, 2017?

ANSWER: The government will not occupy (with personnel) the MTC until the project is completed. The MTC equipment will be delivered and stored in this area following 15 April 2017.

b) Can the April 15, 2017 date be extended?

ANSWER: No.

c) Can the level of finish of the MTC area on the April 15, 2017 date be reduced?

ANSWER: No.

d) Which room numbers are included in the MTC area?

ANSWER: Room C113 (MTC Sim Area 1), C120 (Brief), C125 (MTC Sim Area 2), D101 (Server), and D102 (Brief).

e) Will bathrooms, hallways, breakrooms or other support facilities adjacent to the MTC, in the building, be required to be completed by the April 15, 2017 date to allow for the government to occupy the MTC?

ANSWER: No.

f) If these areas are not required, who is responsible for providing temporary facilities for government employees?

MTC?

ANSWER: The area will not be occupied by personnel. Only government inspectors will be moving through the site as in any other government project.

j) MTC is to be commissioned prior to April 15, 2017. Will the MTC area be required to be re-commissioned upon substantial completion when the entire project is commissioned?

ANSWER: No. Unless the startup of the remainder of the facility effects the systems in that area.

k) LEED certification for clean air will take place at project completion not at MTC turnover.

Will we be required to do duct cleaning and maintain clean air levels in MTC during the period between April 15, 2017 and project completion?

ANSWER: Yes, you will need to provide filters at the return-air and the system filters, and a final duct cleaning if needed for LEED certification. You should only need limited access back into the MTC area after 15 April 2017, as it is on its own system.

l) Will a portion of the construction site be required to be completed prior to April 15, 2017 to allow access?

ANSWER: No.

m) Are we to have the parking lot complete before April 15, 2017 to allow for government parking?

ANSWER: No.

83. What is the typical approval duration for personnel listed on the Entry Authorization list as described in Specification Section 010000 General Requirements?

ANSWER: The approval time to allow access on base (through DBID) is a minimum of 72 hours, and should not take much longer than that. Once approved they will have access as long as they are required to complete their work on the project. For instance the project superintendent will be approved for the duration of the project, where a subcontractor installing the temporary fencing may only be approved for a week or two. The duration is task specific.

84.

a. Existing sliding doors (two on each side of the vertical lift door) – Bottom rail: Facility personnel stated during the site visit that weather changes cause the bottom rail to curve up and makes door operation very difficult. There’s no mention of repairing or replacing of bottom rails in specifications. Do we provide repairing or replacement of bottom rails as an option?

ANSWER: No option will be provided for the repairing/replacement of bottom rail.

89. QUESTION: It appears that power is to be disconnected to the building at the beginning of the project, and that the existing electrical gear, MV XFMR, and generator/enclosure are to be removed, so all civil work can begin and then the new service and generator enclosure reinstalled after all new concrete and asphalt is finished. Is temporary power required within Building 909 during construction, the electrical drawing E002 references two different sets of trailers requiring temporary power and where to obtain the power, but nothing is indicated for the building itself; if temporary power for Building 909 is required, what is the source for the temporary power and are there any other specific requirements or specifications?

ANSWER: The generator and enclosure will be removed and stored to complete the equipment and concrete pad. Temporary power is not required in building 909 for the government’s purpose. Only what is required by the Contactor. Contractor is to provide temporary power and power panel to distribute power to lights and other construction needs while electrical SWBD and primary feed is being demolished and replaced.

90. QUESTION: As mentioned above it appears that the existing generator/enclosure is to be removed and reinstalled per C002, yet E003 states the generator is to remain and not part of the scope of work, also electrical one-line on E701 references that the generator is to be by others at a later date,

a. Will the new generator be installed, after the project is finished?

ANSWER: Yes. Drawing C002, is correct. The generator shed needs to be removed to allow the pad to be replaced. The new generator is not part of this project and will be installed after this contact by others.

b. Please clarify the generator scope of work, is it the electrical contractor’s responsibility to remove the existing generator and enclosure, and then re-install the existing and perform all necessary startup & testing procedures?

ANSWER: The generator scope is to:

1) The electrical contractor is responsible for removing and re-installing the generator and enclosure.

2) Disconnect existing generator from existing ATS. Do not demolish.

3) Remove conductors and conduit between generator and existing ATS.

4) Install new ATS in existing generator enclosure as shown on drawings with feeds to SWBD and EP1 located in Bldg 909.

5) Reference drawing E003 for additional demolition scope for generator enclosure.

6) Reference drawing E100 and E200 for additional installation scope for generator enclosure.

Testing:

1) No testing is required to the existing generator.

2) The new ATS is to be tested before construction completion. To test ATS, a temporary generator is to be provided.

c. Is just the enclosure to be removed and reinstalled?

ANSWER: Yes, the enclosure and all contents is to be removed and reinstalled. With keeping in mind the additional scope for this enclosure.

d. Will all generator work be performed by others with the exception of the new ATS & Panel EM-1?

ANSWER: The generator will not be used during the period of construction.

92. QUESTION: Both electrical drawings E007 & E110, Detail 4, reference Fire Pump XFMRs, but electrical one-line on E701 does not indicate any XFMRs associated to the Fire Pumps, are there any XFMRs to be installed for the pumps?

ANSWER: There are no XFMRs for the fire pumps. Just disconnects as shown on the one-line diagram E701. The feeder tag is incorrect. Instead of XFMR-FPCX, it should be DISC-FPCX (see amendment 0006).

93. QUESTION: Are the new feeders for the fire pumps to be routed overhead once they enter the building similar to the condensing unit feeds shown on E101, or is the intent for saw cutting of the existing slab and these new feeders be routed underneath?

96. QUESTION: The grounding riser schematic on E402, Detail #1 indicates new 4/0 bare copper to be installed from the main building ground bus in the basement under the first floor, is all of the existing 1st floor slab to be removed during construction allowing us to install the grounding cables this way? S009 indicates concrete saw cutting & removal of the slab to accommodate the new structural & plumbing work, but not any electrical, if the existing slab is to remain with minimal removal, should these new grounding cables be installed overhead and in conduit to protect from damage?
