Question: Drawing C-001, under "Survey Notes", there is a note of a field survey completed by LDSI Dated March 2017. Please provide this survey.

Answer: The topographic survey performed by LDSI is depicted on sheet C-101 'Existing Conditions Plan'.

Electronic files of the topographic survey will be made available to the contractor after award.

Question: On Structural drawing S-001 under foundation general note 2.1.C it is saying that undocumented fill under the Hangar site is to be removed and replaced at a depth ranging from 3 to 5-1/2 feet, and depths from 5-1/2 feet to 12 feet at the C17 Simulator building. These ranges are very wide and will have a significant amount of cost increases depending on how much material to be over excavated.

Question: On dwg FA-111, room TER S112 is missing a smoke detector. Please verify this is correct.

Answer: Yes, a smoke detector should be provided in TER S112. See sheet FA-111.

Question: On dwg FA-111, vestibule S101 has a symbol for GAP. Please indicate what this is.

Answer: The "GAP" referenced in Vestibule S101 on drawing FA-111 should be a "ANN". This is a remote LCD type annunciator. See sheet FA-111.

Question: On EP111, key note 23 is used for various areas with demountable partitions. However, there is no A-111A architectural drawing do not indicating demountable partitions for the Simulator building.

We assume key note 23 does not apply. Please verify.

Question: Dwg TS401, detail B1 shows new ductbank from the pullbox merging into esisting conduits running south from Hut 72. We assume that is is incorrect and we are to install a new concrete encased ductbank as shown on TS101. Please verify.

Answer: TS401 with indicated conduits and termination is correct and does not conflict wih TS101.

TS401 provides additional details on the connection at B72.

Question: Regarding the BAS requirements in Spec section 23-09-23 Part 1. General 1.1 Summary A. it calls for the new building’s BAS to be an addition to the existing Alerton base-wide BAS (server).

The existing server has several branded controls systems tied into it. Some are directly integrated into the Alerton server via branded software (Basically all of the Alerton building BAS’s) and some other brands like Schneider are accessible through the Alerton server via a hyperlink to that particular Schneider building BAS. A representative at the pre-bid meeting from the National Guard said that the intent was to provide a native BACnet controls system at the building that would be accessible through the Alerton server. Basically the only true integration (for the purpose of control from the Alerton server) to the Alerton server would be via an Alerton building BAS. However, this approach would eliminate any other controls vendor from submitting a bid, thus disallowing a competitive environment for this part of the project, unless the use of hyperlinking to the Alerton server is acceptable. It appears that the owner’s intent is to have a vibrant field of competitors for this project and to allow open-source, nonproprietary equipment. Will the owner accept server access in the form of a hyperlink to the new building BAS (which would be BACnet with specifically a Tridium JACE front end), similar to the link to the Schneider system?

Answer: Ascent Compass by Alerton is the standard for the base-wide BAS and the new control system provided for this project shall be fully compatible with and integrated into the existing Alerton system as specified in Section 230923, Par. 1.1.A and Par. 2.1.A. Using a third party front-end, gateway or network interface that utilizes non-Alerton software, tools or additional licenses is acceptable provided the GC offers O&M training on the new software to base facility personnel and that the all software to include but not limited to, smart meters, dash boards, points, etc. intergrate seamlessly with the Alerton system. See Specification Section 01 79 00 para. 3.3.A, the contractor is to provide demonstration and training for HVAC controls listed in specification section 23 09 23 per the training schedule provided in this section.

Question: Reference A-701. Wall types OG and 1G on A-701 are noted to be a STC 55 wall type. In order to get this rating, the wall needs to be fully grouted or use of sand in non-reinforced cells. Please verify these wall types need to be STC 55 and should be fully grouted or sand used to meet the STC rating.

Answer: Refer to revised drawings A-111 and A-701 for partition clarifications requiring an STC 55 rating.

Question: Are we required to paint the exposed Roof and Floor decks? These decks are specified as factory primed with manufacturer’s standard baked-on, rust-inhibitive primer (see section 05 31 00 Para. 2.2 & 2.3). Generally, baked-on paints are not required to be painted. The finish of a bake-on paint surface is slick and glossy and it would have to be primed with a Bond Primer that is not included in the specs. If exposed decks are to be painted, can you provide specs for this bond primer?

Answer: See updated drawing A-602 for exposed structural steel to be painted.

Question : Exterior Painting Spec. Section 09 91 13, Paragraph 3.3E indicates to paint exposed MEP Items but it doesn’t list the ductwork. Are we supposed to paint the ductwork?

Answer: There is no exterior ductwork. However, (Interior) exposed ductwork that is insulated/double walled shall be provided with an integral PVC outer surface as indicated in documents.

Question: Interior Painting Spec. Section 09 91 23 doesn’t indicate to paint the Exposed MEP items.

Is this correct?

Answer: Interior Painting Spec 09 91 23 references substrates/surfaces that define painting requirements which include applicable MEP items. See revised Sheet A-602.

Question: Are Overhead Coiling Doors field finish Painted? Spec. Section 08 33 23 indicates Factory Prime Finish with Manufacturer’s standard color. Manufacturer’s standard paints are generally finish paint and not only primed paint.

Answer: Overhead Coiling Doors are to be factory finished. Refer to updated Spec section 08 33 23 - OVERHEAD COILING DOORS for finish requirements.

Question: Please confirm all the exposed structural steel in the hangar is to be painted. Does this include the metal deck as well?

Answer: See revised drawing A-602 for exposed structural steel to be painted.

Question: Please verify below grade foundation wall construction joints will be approved at avg 100' spacing. Drawing S-001, Div 03, 3.1.H says construction joints in walls shall be keyed and placed at approved locations. 3.1.F. says 10-15' intervals, but these are for joints in retaining walls, not foundations. Please verify 100' will be approved.

Answer: CONTROL joints shall be provided at 10 FT to 15 FT intervals in walls per the General Notes.
