Solicitation Number W91242‐17‐B‐0005

National Guard Readiness Center, Wilmington, North Carolina

80. Question: One of the requirements listing within the SOW states that equipment must be compatible with the Tridium BMS, while our products communicate through a proprietary communication network we do have an API developed that allows our equipment to communicate with certain third party systems. Is there someone that would be able to look at our

API and determine if it would work for the NCNG? It does also state in the SOW that the NCNG has the ability to write their own programs within the Tridium software, so I assume this would allow the NCNG to be able to write programming that would work with any/all third party systems. Is my assumption correct?

Answer: US Army NETCOM issues the Certificate of Net worthiness (CON). Currently the only approved system that has a CON, is non‐proprietary, and allows full access to us for programming is Tridium. Refer to Attachment 4 (Brand Name J&A) of the Solicitation.

We recommend a 150 MPH wind load and the Seismic Category C as required for the location for Risk Category III and IV building types.

Answer: See amendment 0002, revised Section 133423.10. section 2.1.A.5 for wind load requirements Reference specification 133423.16 section 2.1.A.6 for seismic requirements. The fabricated storage building shall be Risk Category III. The Seismic Importance Factor shall be 1.25.

118. Question: Electrical supply of 480 voltage /3 phase ‐ We can provide a transformer to accept a

480v/3ph electrical supply, but the alarm panel and water heater will need to be provided by others in the field using a separate connection.

Answer: Provide electrical power service per Section 133423.10 Article 2.2.H. The general contractor is responsible for split of responsibilities and means and methods.

119. Question: Audible and visual alarms ‐ Alarms for interior use are not standard items for chemical storage buildings, since these buildings are not a personnel occupied buildings. Any audible and visual alarms supplied will be mounted on the outside of the building and be non‐ explosion proof electrical options as required per industry standards. Any audible and visual alarms required for inside the building will need to be supplied by others and installed in the field

122. Question: Ventilation ‐ FM requires 6 air changes per hour for buildings with mechanical ventilation. Minimum air changes per hour cannot be confirmed for passive ventilation buildings, so a mechanical ventilation system is required.

Answer: Specification Section 133423.10 Para 2.2.E provides the heating and ventilation design requirements. Space was designed per National Guard DG 415‐1, Table 3 Mechanical

Requirements ‐ Part 1. FM not applicable.

123. Question: Eyewash and shower water supply ‐ We can provide an eyewash and shower to be shipped loose for field installation by others, but we will not provide the tank‐less water heater or water supply to the eyewash and shower. Installing the water heater inside the chemical storage building require a Class 1 Division 1 explosion proof water heater that will add a minimum of

$12,000 to the project. It is recommended that we ship the eyewash and shower loose and the contractor providing the water supply provide the installation of the eyewash and shower in the field at a nearby location. This will eliminate the need of the eyewash and shower being mounted on the exterior of the building.

Answer: Per Section 133423.10 Article 2.2.R. Emergency eyewash and shower as well as tankless instantaneous water heater to be provided and installed exterior to building, outside of Class 1, Division 1 requirements. Provide heat trace as required by Section 133423.10 Article 2.2.I. The
