The intent of this question is unclear. Please provide examples of items which “do not seem to apply” for review and comment.

Other cmu manufacturers are acceptable provided they can provide a masonry unit which is similar to the Trenwyth block in color, texture and physical properties.

Steel fabricators shall be AISC certified per the specification requirement.

Steel erectors shall be AISC certified per the specification requirement.

The metal roof panels for the Ammo Breakdown Building are non-insulated.

The metal roof panels for the Classroom Building are non-insulated. Your attention is called to the sprayed on foam insulation shown in Section 5/A501.

Butler is the “Basis of Design” for non-insulated wall and roof panels but other manufactures providing a “or equal” product are acceptable.

The roof and wall panel of the Control Tower are to be insulated metal sandwich panels having a R value of R-28 for the roof panels and R-14 for the wall panels. These panels will not necessarily match the profile of the non-insulated panels but should match the color.

The window schedules in the drawings refer to note #1 in the Remarks Column.

Note #1 calls for 1/4" polycarbonate glazing. Provide sealed double pane units consisting of ¼” polycarbonate tinted outer-pane, ½” dead air space and ¼” polycarbonate clear inner-pane.

Refer to 1/A-110 for location of CMU walls, columns, and slab edges.

Refer to 1/A-120 for location of CMU walls and slab edges.

Final determination of acceptable soil bearing strata shall be provided by an Utah Professional Engineer or his designated representative per Foundation Note 4. If the geotechnical engineer determines that native soils at the base of the excavation are acceptable, then foundations may be placed on the native soils. If the geotechnical engineer determines that natives soils at the base of the excavation are not acceptable, provide structural fill as noted. The Contractor will have to determine the level of risk they want to assume in their assumptions regarding the fill. If fill is required, the cost will be the responsibility of the Contractor.

Steel roof deck may be omitted.

Delete note 8 and Sheet A-125 and corresponding requirement for “Service Identification” Sign. Provide building signage as called for in detail 4 sheet A-125.

The components will be stockpiled at a location designated by UTARNG. They will not be re-assembled by the contractor. Location of stockpile will be on site of the MPMG Range. West of the current M-31 range tower. Contractor to coordinate with Camp Williams Range Control.

Design floor gratings in accordance with NAAMM MBG 531 to support a live load of 250 pounds per square foot for the spans indicated, with maximum deflection of L/240, or ¼”, whichever is greater. Slip resistance requirements must exceed both wet and dry coefficient of friction of 0.5 as tested in accordance with ASTM F 1679.

Please refer to notes on Sheet C-701 regarding seeding of Disturbed Areas with “seed species appropriate to the season as provided by the Utah Army National Guard”. The Contractor will be responsible for “stabilizing” all disturbed areas in accordance with the Construction Sequence, and all of the Erosion and Sediment Control Notes (General and SWPP) shown on Sheet C-701. Please refer to General Note 3 on C-701 for requirements for permanent stabilization. Allowing “the natural vegetation to spread onto these areas” would not be acceptable stabilization. UTARNG to confirm.

Letting these areas naturally colonize or seeding in turf grass, without an irrigation system, will result in cheatgrass and other fire-prone or weedy vegetation and will worsen the wildfire situation.

The INRMP requires native species for revegetation. Species that are native to that area will establish best. So, they ought to use a mix of native, fire-resistant species for any reseeding or disturbed areas. It would take some time to research and develop that mix.

The water point at the Tickville Maintenance building will not be available. However, water is available at no charge to the contractor at the Camp Williams Beef Hollow water tank. The UTARNG will not be held responsible for any temporary or emergency interruptions to this source. If there is a temporary or emergency interruption with Camp Williams water, the contractor will still be responsible to provide construction water to the project.

As indicated in Note 1, Detail 3, on Sheet C-530, the smaller dimensions are for the 25M Zero Range, and in like manner, the Small Interior Limit Markers are for the 25M Zero Range.

Target Boots are placed at the center of each Zero Lane at 25M and at the center of each even numbered Zero Lane at 10M. Please refer to Sheet C-173 for 25M Zero Target Boot location coordinates.

If a flagpole is to be provided, please provide specs.

Note 1 on Detail 2/C-533 references Electrical Drawing E-504 for Flagpole Information. Detail 2/E-504 calls for a 5" x 20'-0" Round Non-Tapered Aluminum Pole with Hinged Base. Basis of Design for this pole is Lithonia CAT. #RSAH 20 5 G, 4-8 SQ. FT. EPA with 1.3 Wind Gust Factor.

The INRMP requires native species for revegetation. Species that are native to that area will establish best. So, they ought to use a mix of native, fire-resistant species for any reseeding or disturbed areas. It would take some time to research and develop that mix. The proper mix will be coordinated with the Envirnmental Office at Camp Williams.

Sheet C-050 Note 2 states the tower is to be "moved" by the contractor to an undetermined area on base. The questions are 1) does the term "moved" mean reassembled? And 2) can you give an approximate distance the tower is to be moved to from the site?

Salvaging involves disassembling the existing tower(s) into small enough pieces for transport to a storage yard to be determined by UTARNG. The contractor is not required to reassemble the tower(s). UTARNG will designate the location where the tower(s) will be stockpiled. . Range Control is asking that both towers and components from the firing line be salvaged. Materials will be moved to an area within the foot print of the MPMG Range which the contractor will coordinate with Camp Williams Range Control (stockpiled west of existing M-31 Range).

Sheet C-050 Indicates a structure to be removed completely, however, there are no details indicating what kind of structure it is, size, or foundation material.

The building in question is a metal shed on a concrete slab. It was anticipated the contractor would review this building at the site visit. A photograph is attached.

Note #1 calls for 1/4" polycarbonate glazing. Provide sealed double pane units consisting of ¼” polycarbonate tinted outer-pane, ½” dead air space and ¼” polycarbonate clear inner-pane.

On page S-002 under reinforcement masonry Item 9. No control joints are required but the architectural show a control joint every 20 feet. Which one are we going with? A-501 5/a-501 shows 1# 4 bar every 24 inches on center but S-002 shows a typical space as 1 # 5 bar at every 48 inches?

CMU walls should be constructed and reinforced per the notes and details on sheet S-002.

Section 015000 2.1.B requires the contractor to provide a field office “of sufficient size to accommodate the needs of the Owner, Architect, and construction personnel.” Please clarify what the Owner & Architect needs will be so we can provide the required space?

Normally a small trailer.

Regarding the Outer Limit Markers, are these signs, or the specialized paint for the signs, Government Furnished? A specification regarding paint for the exterior signage is not noted. Please provide information.

The Outer Limit Markers and the paint are to be supplied by the Contractor. The paint for the Outer Limit Markers is the same as for the rest of the range markers except for the color. The paint for the markers is not a specialized paint. The paint must be an exterior paint which will hold up to the outside changing weather conditions.The color for the markers is as shown on sheet C-530.

Is printed vinyl acceptable in lieu of paint on exterior signage?

This would be a user decision. The Contractor would have to certify that the Vinyl would be as good or better than the paint. UTARNG go provide input. The UTARNG would need to see the proposal from the contractor to make a decision.

The plans show limits of disturbance and also access roads outside the limits of disturbance. Please clarify what is part of the project outside the areas identified and limit of disturbance.

SAIC reviewed the drawings and could not find any work outside the defined construction limits. Could the contractor provide an exact location and sheet reference where they saw work outside the construction limits?

We asked LTC Filoso of UTARNG to define the ground snow load in a 06 /06 / 2011 e-mail. In item 4j of the 95% Review Meeting notes (dated 09 / 12 /2011), UTARNG directed SAIC to use 40 psf for ground snow load.

We are unclear where the 45 psf snow load reference comes from in the question. Sheet S-001 lists a ground snow load of 40 psf and a flat roof snow load of 28 psf. These values are consistent with the design criteria and snow load calculations in the signed and sealed calculations dated 10 / 28/ 2011.

"The UTARNG has made every attempt remove the UXO from the construction area. After the UXO clearance operations are completed by the UXO contractor, the risk level should be low, but the risk is never completely eliminated. It is incumbent on the Contractor to understand the risk and obtain the appropriate insurance coverage for the project and in accordance with the contract documents. UTARNG does not provide any insurance or liability coverage for the contractor or his personnel. The contractor's personnel will be required to undergo contractor awareness training so everyone working at the site knows the appropriate actions if any suspicious objects are found during the construction."

"The takeoff shows that the 15KVA and 1 of the 50KVA require a meter. The transformers are 1ph pad mount which includes a clamshell type cabinet. The movement of the clamshell would not permit a meter like a 3ph which has swing outdoors. Is the meter required to be included in the transformer? Also there is no detail in the spec regarding what type of meter is required. Can you get clarification?"

The meter may be installed remote from the transformer enclosure. Primary metering is required at these locations for the UTARNG to monitor the consumption at each Range location. The meters need to be standard utility grade for the voltage level servicing the installation.

"The one line shows that the transformers have a 7200V primary, however the drawings nor the spec indicate if that is a 7200 Delta, 12470GY/7200 or 12470Y/7200. Can you find out what the system configuration is?"

Per the UTARNG, the upstream 3-phase voltage is 12470 volts. At the Range location, the voltage is 7200 volts, single-phase. The area is powered off a #2 ACSR conductor with a load of 12 amps.

"Due to the length of the feeder from T-5 to T-6 manholes are required. I have no spec anywhere on manhole dimensions and sizes. I have included 7- 4'x 4' manholes. Will this be acceptable? Will there be any specs provided to size this item?"

No additional specifications will be included. Sizing of handholes and/or manholes furnished by the Contractor shall be done per the National Electrical Code for the voltage level where they are installed.All needed handholes/manholes will be the responsibility of the Contractor.

"The feeder from T-1 to T-7 shows it in base bid #1 along with the xfmr. I have included the feeder from T-7 to MDP1 and the MDP1 panel in the Alt #1 breakout. Is this accurate?"

The entire underground feed from the UG distribution switchgear to transformer T-7, the transformer itself, and the distribution panel for the 25 Meter Zero Range is ABI-1.

Is the Control tower and the Class Room Building not needing to be on the sites wide area network? Or are they on a standalone network? If they need to be on the campus wide area network where does and how much fiber and copper is needed.

The service to the Site is being installed under separate contract. The Drawings, specifically sheet E-140, note what is required in the way of communications wiring.

Civil drawings on page C-176 show SAT positions 7-V21 and 8-V21. The electrical drawings don't show these emplacements on the prints or the one line drawings. I am guessing these do not have electrical and teledata. If so please indicate the requirements and locations for these items?

No power or data is required at these locations.

Civil drawing C-122 shows the entire underground feed, XFMR, and Panel MDP1 going on Alt #1. Electrical sheet E-601 shows only the feed from the xfmr and panel MDP1 on Alt#1. I have followed the Civil drawing and included the entire run, xfmr, and panel MDP1 in Alt #1. Is this correct?

E-601 depicts the same information as that shown on the Civil Drawings. The entire underground feed, transformer and panel for the 25 Meter Zero Range is ABI-1.

where is T8 located? I do not see it on the one-line or anywhere else in the plans. In the solicitation under item 0004 it states; . Electrical items shall include the new underground primary electrical feed from transformer T1 to T8, transformer T8, and main distribution panel MDP-1

There is no T-8 designator on the Project. Only transformers T-1 through T-7 are included in the Contract Documents.

Could you please provide a resolution to following conflicting specifications: Spec Section 01 40 00 1.1 C states that the Contractor to provide all testing and inspections (see attached). Spec Section 32 20 00 3.19 A states Owner to engage geotechnical engineer to test soils (see attached) Will the contractor be permitted to contract the same geotechnical engineer used by the owner to perform the other inspections required for this project if they are qualified to perform such inspections? Who is the owner contracting for the geotechnical inspections?

All construction testing services including Geotechnical services are the responsibility of the Contractor. The Contractor will pay all costs for the construction testing services. The Contractor may utilize the same geotechnical testing firm who performed the original testing. The government will not be providing any of the testing services.

Regarding Sheet C-132, please provide target information, like previous sheets.

We are unclear on this question because Sheet C-132 seems to have all the target information in the Key Notes. We assume you are referring to the missing key notes on sheet C-129. Below are the missing key notes from C-129:

Key Note 5– 12”graded crushed aggregate surface RE: C-301 Key Note 28- FOR TARGET DETAILS RE: C-503 STATIONARY INFANTRY TARGET (P), C-504 WIDENED STATIONARY INFANTRY TARGET (WP), C-505 MOVING INFANTRY TARGET (IM), C-507 STATIONARY ARMORY TARGET (V).

Key Note 29- maintenance trail Key Note 32- SIT grading Detail RE: 2/C-503.

Detail A/C-502 does not adequately detail rebar reinforcement in all walls. Please clarify.

Detail A/C502 calls for #4 rebar @ 1’ – 0” on center each way, centered in the slab and all walls. (4) # 6 x 1’ – 6” @ 1’-0” O.C. Bent Dowel bars are shown for each of the four corners and #6 x 1’-6” Bent Bars @ 1’-0” O.C. where the walls and slab intersect.

Regarding details A/C-503, A/C-504, A/C-505, and A/C-511 rebar reinforcement is not detailed in wing walls. Please clarify.

Per the call outs on Details A/C-503, A/C-504, A/C-505, and A/C-511 the reinforcing for the side wing walls are the same as the front wall. On Detail A/C-503 and A/C-504 the rebar laps must be a minimum of 18”. On Detail A/C-505 and A/C-511 the rebar laps must be a minimum of 12”. The rebar shall be centered in the walls and slab as per the notes. .

Regarding Outer and Interior Lane Markers. Plans do not specify small or large sign on the drawings. Please clarify On sheet C-530, Detail 2/C-530 “Interior Limit Markers”, the small interior limit markers are for the 25M Zero Range and the large markers are for the MPMG Range. Detail 3/C530” Range Lane Markers”, the smaller signs are for the 25M Zero Range and the large signs are for the MPMG Range.

On sheet E-101 thru E-112 it calls for 15KV #2 conductor w/133% insulation and jacketed concentric neutral in 4" sched 40 conduit. On Sheet E601 it states "route (1) 15KV #2 conductor with 133% insulation" this is not correct. Please give the correct # of conductor.

The callouts for the wiring are correct on sheets E-101 through E-112. The same nomenclature should be used on sheet E-601.
