CATM Remodel Bidding Q&A

1. Can the schedule be submitted on a larger page size than 8-1/2"x11"?

a. Yes the Schedule can be submitted on 11X17. (G Shirley 509 CES)

2. Is there any lead abatement required in this project?

b. No (G Shirley 509 CES)

3. Specification 02 41 19 Selective Demolition 3.2B calls for "an engineering survey of condition of the building to determine whether removing any element might result in structural deficiency". Has this been completed by the EOR to establish the design?

a. No, this is the responsibility of the contractor and dependent upon the contractors specifications “means and methods”. (G Shirley 509 CES)

4. Is there any special recycling requirements for the project waste?

a. There will be expectation of normal construction operations with the project waste diversion. (G Shirley 509 CES)

5. Stage area?

a. Refer to sheets C4.02 and C1.01. (G Shirley 509 CES)

6. Unable to locate specification sections 31 or 33 for earthwork, water service line and storm drainage in the bid documents.

a. Specifications are on the civil drawings. (M. Christensen F+W)

7. Unable to locate specification section 09113 Exterior Painting that is referenced in sections 05 and 09 in the specifications.

a. If a UFC standard for exterior painting is not available, utilize MPI (Master Painter’s Institute) recommendations for material preparation and finish. To the best of my knowledge, exterior items that will need be painted are as follows:

i. Access panel doors on east and west wall (factory finish to match siding is preferred. If not available, factory primed and kynar paint to finish metal wall panel.)

ii. Exterior downspouts (and supporting unistrut) on east and west elevations are noted to be galvanized. If a painted finish to match prefinished metal wall panels is desired, then they’ll need to know)

iii. Guard rails around the exhaust units (not attached to the building) are noted to be galvanized. If a painted finish is desired, they’ll need to know.

iv. Hollow metal doors and frames to target shed and the range will need to be painted.

8. During the site visit, it was observed that the existing truss girder and bridging system has a substantial amount of rust and scaling. Are only the future weld connections to the existing truss system required by new work to be primed and painted?

a. I think it could go either way. Since it's still an unconditioned building, it would extend the life of the trusses to clean the rust and repaint but I don't think it's something that has to be done now for the current integrity of the building. If significant rust or scale is observed, notify the contracting officer. I would say that the original intent of the drawings would be for the new welded connections and any moved/removed bridging locations to be repainted. (V.

Baehr PMA)

(G Shirley 509 CES)

FirePrev DG WAFB 10 Mar 16.pdf

35. Being we now have a total enclosed non sprinkled building should we have a fire alarm system that encompass the entire building using heat detectors or liner heat detection?

a. From ETL 11-18:

7.2.10. Fire Protection. Burnt propellant, muzzle flash, freezing temperatures, and bullet damage all conflict with the operation of standard fire protection design. To resolve these conflicts, the Air Force only requires sprinklers when the range is constructed integral with range support facilities like training rooms and cleaning rooms. Sprinklers are required in the range support facilities and on the firing platform area, but are not needed in the downrange area or at the target area. Smoke and infrared detectors are also problematic and impractical in the downrange area or at the target area because of the amount of smoke and periodic muzzle flashes from the weapons. No detection is required in the downrange area and none in the range support facilities or firing platform area since these areas are protected by sprinklers. Assume metal bullet traps— rubber, foam, and other materials used for bullet traps may require dedicated additional fire protection features per the manufacturer’s recommendation.

Egress paths shall not require travel downrange from the primary firing line.

Downrange space shall not be included in calculating minimum egress capacity requirements. Egress marking, emergency lighting, and egress door hardware shall not be required downrange of the primary firing line.

(M. Christensen F+W)

b. Refer to architectural code plan on A0.01 for fire protection requirements/mandates. A quick glance at IBC 907 shows it is not required unless over 300 occupants (matt to confirm) even though we have shown a new panel with devices at the only point of occupancy (and to minimize damage).

c. See previous note that supersedes code mandated items as enforced by WAFB design guides

a. Provide NEMA 3R

76. Is there a designated area to stockpile dirt/ spoils?

a. See Question 53.

77. Please reference Sheet S3.1, detail 7. Unclear of the intent. Could additional detail be provided to show how this closure section is attached (i.e. plan view)?

a. The triangular portion is to seal the opening at the two side walls. See 9/A7.01 for additional information. Intent is to completely seal the range.

78. Panel shows a “Beacon” light. What does this do?

a. “Range-In-Use” light and operated from the control tower.

79. Panel shows an “auger” button. Any wiring details for interface to the auger system?

a. No wiring details provided. System is existing. Per plans this system is to be integrated into a new control plans.

80. Panel shows a dust collector, but not sure where/what that is. Any additional details?

a. Refer to power plan for location of existing dust collector. Per plans this system is integrated with new control panel.

81. Lots of manually controls for system that has building static control. Should there be an Hand OFF AUTO position on the Main switch that allows the system to manage supply/exhaust fan control? DP control won’t work if Exhaust fans have been turned off manually.

a. [Cory Wilson] Please refer to M7.01 for all DDC control interlocks and enable/disable manual controls. The intent is a fully automated system with manual initiation by the main control activation switch. See sequence of operation on this sheet. The general system operation described if on/off were initiated to skip this equipment in the auto mode (main control on). However, it can be changed that all of the on/off should in fact be HOA to simplify this in order to isolate and provide maintenance/troubleshooting if required.

82. Any time-out requirements for any of the fan systems? (e.g., after 16 hours of operation, fans shut down)? Or run continuously if someone forgets to turn off.

a. [Cory Wilson] we can agree that an overall timeclock function should be put in place so that any initation of the system starts a shutdown countdown after 4 hrs (adj). if USAF operation is expected to be longer they will have to just manually go initiate main control again for another 4 hours.

83. Would like to confirm that all radiant heaters are manually control with no override disable above certain temperatures?

a. Cory Wilson] per detail on sheet E7.02, install in series with on/off toggle initiation switch a line voltage thermostat (open on rise) with digital readout (equal by Honeywell or white rogers). Control circuit shall be 120V for thermostat and switch (unswitched hot).

84. Any metering requirements? Seems most WAFB projects have had requirement to monitor electrical demand at each building and totalize at Base’s EMCS. Ditto for water use. Plans show old meter coming out, but no new meter going in.

a. No metering required.

85. Do the existing joist get prepped and painted?

a. Yes (G Shirley 509 CES)

86. It is my understanding after the site visit, on detail 6/S3.1 that these repairs are referring to the joints and minor spalling between the existing foundation and original slab. Please clarify.

a. This detail is specifically referring to the deterioration of the concrete in the trench. It is cut on the plan at each end of the trench where the deterioration is the worst.

87. The specifications call for air barrier testing. Pressurization of the existing facility, even after the renovations, is going to be very difficult. Was this the intent of the Air Force?

a. The primary goal of this project is to enclose the range. Recommend test be conducted before exterior finishes are applied to determine areas that are not air-tight and address them appropriately (sealant, etc.). Intent of testing is to assure that new ventilation airflow will not “short-circuit” or weaken due to leaks in envelope. Coordinate modified tests with 509 CES and anticipate construction of temporary barriers if needed. This is not an attempt to meet sustainability requirements, it is intended to prevent failure of the ventilation system due to air leakage of the envelope north of the bullet trap.

88. Section 054000 3.5A – what type of testing and inspections will be required? Is a visual inspection satisfactory?

a. Yes, visual inspection is satisfactory (G Shirley 509 CES)

89. Section 07413.16 2.2 B-2 – specifications call for #20059 color. Can the contractors utilize a manufacturer’s standard color?

b. Yes, selection will be made from mfgrs standard color palate (G Shirley 509 CES)

90. Section 074213.13 2.2B-2 – specifications call for #23758 Antique Linen color. Can the contractor utilize a manufacturer’s standard color?

c. Yes, selection will be made from mfgrs standard color palate (G Shirley 509 CES)

91. Painting – Sherwin Williams is not included in the approved vendors list. Are they considered an acceptable manufacturer?

d. Yes (G Shirley 509 CES)
