Q12: 1. We saw that the project is scheduled for 13 phases. Will these phases be back to back, meaning we can go from one phase directly into the next. Or will there be down time between phases, meaning we will not have any work and no man-power presence on site?

2. It was stated that plant operations will not stop during construction. Does this mean crane activity and men on the ground will be working simultaneously in our work area?

3. If the answer to question #2 is yes, what would be the safety protocol when working above/in the same area as plant personal and crane activity?

4. Is the Fire Protection Scope of work to be done during normal working hours or off hours?

A12: 1. No down time between phases.

2. Yes - To help minimize conflict and reduce coordination efforts work in the production areas is to be performed during second shift. When necessary, coordination will be made with the USACE COR and building occupants to de-conflict work areas.

3. To the extent possible the Contractor and Government should limit this situation through coordinated effort. If required then the Contractor will need to take measures to ensure there are no falling debris hazards to those working below.

4.See Specification section 01 14 00 paragraph 1.2a, “The B110 will remain in operation during the entire construction period. The Contractor must conduct his operations so as to cause the least possible interference with normal operations of the activity. The Contractor shall assume the scope of work between column bays 23 and 69 will be performed during second shift.

Q13: Please clarify the completion date.The Solicitation/Offer page #1 states 540 days and spec.section 011100 pg.1 para 1.4a states 365 days,which is it?

A13: Solicitation governs with 540 day requirement. Change spec.section 01 11 00 pg.1 para 1.4a to state 540 days

Q14: Can the existing sprinkler systems be removed at the start of each phase in their entirety,or will the new system have to be installed next to the existing,and put in service prior to removal of the existing system?

A14: The existing sprinkler systems within each phase can be removed at the start of each phase. Existing sprinkler systems in later phases shall remain fully operational until the start of the later phase.

Q15: Is galvanized pipe required for the pump suction piping? Note #5 on drawing FP-001 appears to allow black steel schedule 10.Will the pump suction piping be required to be schedule 40?

A15: Piping from discharge of backflow preventer to control valve downstream of fire pump test header shall be Schedule 40 (except for Schedule 30 for pipe sizes 8 inches and greater) and shall be galvanized on the inside in accordance with bid specification section 21 30 00 article 2.4.1.1.

Q39: Division 22 2.2.3 says to see section 23 07 00 for insulation, no domestic water listed in schedule. Please provide insulation type, thickness and jacket for systems requiring insulation.

Section 23 07 00, does LPS and LPC require to be insulated? If so please provide insulation type, thickness and jacket. Please provide a spec for the condensate pump with required options/accessories. Drawing schedule is lacking A39: Domestic water piping insulation. See attached from standard specifications for additional information which defines insulation type and thickness based on pipe size.

Low pressure steam and condensate piping insulation. Yes, provide insulation as defined in the attached charts. Replace bid specification 23 07 00 tables 1 and 2 in paragraph 3.2.1.5 with the attached.

Q40: We have received the answer to RFI ID 8171468 in regards to the Windows and glazing.

The response did not address what the Charge Weight, Standoff Distance or Level of Protection requirements. Without these 3 pieces of information glazing vendors will not price the job.

Additionally, to price the job glazing vendors need 5 to 7 days to engineer the makeup of the glazing units for pricing. Please advise and extend the bid date so proposals can be made.

A40: UFC 4-010-01 was changed in December 2018. The charge weight, standoff and protection level are not relevant to this situation. See following excerpt from that document:

UFC 4-010-01 12 DECEMBER 2018 3-2 STANDARD 1. STANDOFF DISTANCE. The previous version of Standard 1 established standoff distances to parking, roadways, and controlled perimeters that were based on building construction and occupancy. In this revision of Standard 1, standoff distances only apply to distances to installation perimeters for new construction and additions to existing buildings that are required to comply with these standards. Exception: Existing buildings within an installation perimeter are exempt from this standard. 3-11 STANDARD 10. GLAZING. Glazing that is in compliance with this standard is not required to be designed or constructed for blast resistance. It is intended to minimize hazardous glazing fragments. Apply the following provisions for exterior glazing for new construction or existing buildings that are required to comply with these standards.

3-11.1 Glazing. For glazing in exterior building elements such as storefronts, doors, windows, curtain walls, clerestories, and skylights provide no less than 1/4 in. (6 mm) nominal polycarbonate or laminated glass. The 1/4 in. (6 mm) laminated glass consists of two nominal 1/8 in. (3 mm) glass panes bonded together with a minimum of a 0.030 in. (0.75 mm) interlayer of a material designed for blast resistance. For insulated glass units (IGU), use the polycarbonate or laminated glass for the innermost pane as a minimum. For laminated glass, provide a glazing frame bite in accordance with ASTM F 2248. For polycarbonate, provide a glazing frame bite of no less than 1.5 times the polycarbonate thickness. Monolithic glass or monolithic acrylic used as a single pane or as the inner pane of a multi-pane system is not allowed for the purposes of complying with this standard. Spandrel glass when backed by a structural wall or spandrel beam, translucent fiberglass panels, other lightweight translucent plastics, and glass unit masonry are not required to comply with this standard. Spandrel glass that is open to occupied space must be designed in accordance with this standard.

Q41: We were unable to attend the site visit on 8/22/19, is there any possibility of having a second site visit for this project?

A41: no additional site visits are scheduled at this time.

Q42: Fixture type D8 model number on the fixture schedule calls for a 21,000 lumen industrial, but the lumens column shows 12,600. Which is correct?

A42: Model Number is correct – design is for 21,000 lumen fixture.

Q43: The partial lighting calculations shown on the photometric drawings do not match the lighting fixture schedule on drawing E-601. Please clarify the required fixture types.

(For example: There are 4 different types of E4 fixtures on the partial lighting calculations, but the actual fixture schedule only lists 1 type of E4).

A43: Provide fixtures as noted in the fixture schedule (including changes noted in these responses). Some annotations in the photometric calcs vary from the schedule due to limitations of vendor .ies file documentation

Q44: What is the mounting intent for the type B8 and C8 fixtures? Please provide a mounting detail. I have attached the mounting options for you use.

A44: B8 and C8 fixtures are to be chain or cable hung -suspended to meet the mounting height (floor to bottom of fixture) noted on the drawings

Q45: Is the design intent for there to be 2 emergency control devices per lighting fixture instead of per circuit?

A45: The intent is (1) emergency control device per EM fixture.

Q46: Can a symbols legend be made available for the lighting controls? We cannot identify the differences between the required devices.

A46: Symbols legend is on Drawing E-001.

Q47: Can the sequence of operations be made available for the lighting control design intent?

A47: See Daylight control notes on Drawing E-002 for general sequence of operation.
