The only specified laydown/staging space available for this contract is shown in Volume 2 drawings adjacent to the VMF building. This area would need to be logged/cleared to create usable laydown space. Given the current bid date and 180 day evaluation period, award of the contract would be anticipated in March of 2021. Per spec, logging is not allowed annually from April 01 through Sept 23. This means the specified laydown area will not be available for use until after

Sept 23, 2021. Is there another staging area the Government will make available to the contractor prior to Sept 2021? 66

A temporary small staging area will be provided for this time between contract award and logging operations.

10 is for seismic and antiterrorism protection for Electrical Equipment. Can you please provide the correct spec section for the MV switch gear? 104 See revised EW602. See amendment #006.

Drawing EW602 describes generator and switchgear sequence of operation. Does that mean the MV gear is generator paralleling gear? If so it seems like the MV paralleling gear would come with the generator.

Below are supplier questions for the Hazardous Material Storage Building.

Spec reference: Section 13 34 20

1. Please provide the electrical options required for the Hazardous Materials Storage Building listed in Section 13 34 20 /

# 2.2. No electrical options were included in the specification; however, options will be required for the chemicals being stored.

2. Drawing AB101 shows separate storage bays needed, but the building electrical options and alarms typically required for the storage requirements are not included in the specification.

3. Also on Drawing AB101 the 4 bay chemical storage building will need to be moved out further from the larger building wall, because of the required clearance needed for the electrical options installed on back wall to support the separate bay storage.

4. On Drawing AB101, we recommend that Hazardous Material Storage 119 be quoted as a separate 4 hour fire-rated chemical storage building that will be installed outside next to the larger building with door access directly into the chemical storage building installed on the outside of the larger structure. 106

Furnish interior class 1 /div1 explosion proof LED luminares and switch at doors. Also note the building should be fire sprinklered by manufacturer as noted on the drawings. 2.

Power connection added to sheet EB111. 3. Electrical junction box connection point shall be located on top or side to allow access. 4. Clarification: terminology in specification intended for the prefabricated storage building

(rooms X115-118) rather than room 119.

Section C1 on SB 301 gives foundation detail occurring at metal building column ad the window panel through grid line E.

According to SB 02 this footing is 6 ft wide and 2’-6” deep carrying a 5 inch slab on grade per C1/ SB301.

A cut, C1 /AB301 , through the same area on drawing AB103, shows details at building perimeter of A3 and A4 on AB501.

In these details the metal building wall appears to sit on a curb out board of the slab with rigid insulations sandwiched between this curb and the foundation.

Please confirm there is no curb on top of the 5 inch SOG and that rigid insulation would be placed to the exterior of the

SOG and of the footing. 182

Provide curb per revised structural drawing C1/SB302, exterior insulation is acceptable. See amendment #006.

What are the charge weights and stand-off distances for the project? Translucent Panel Spec 086045, paragraph 1.1 (last sentence) states, “Systems must meet requirements of UFC 4-010-01”. Then in paragraph 1.2, the last line item, it references the 2012 edition of the UFC 4-010-01/DOD Minimum

Antiterrorism standards for Buildings. I cannot get pricing on the translucent panels until I have this information. The blast requirements could change the bay spacing, could require stronger mullions and potentially double walled perimeter I beams. 183

The government established the VMF to be located more than 50 feet on the interior side of a controlled perimeter during the design phase; therefore, construction standoff distances do not apply per Interim Technical Guidance (ITG

2018-02), Implementation of NAVADMIN 026/18 Policy and
