Government Response 13:

The Geotechnical Report is provided in the specifications, as an attachment to 01 11 00.

Question 14:

The proposed detail for the spike plate over a rock anchor bearing plate will not secure the mesh to the slope, as the bearing plate will prevent any contact between the spike plate and rock slope. Is this the intent? Typically the spike plates are secured directly to the slope to engage the mesh against the slope.

Government Response 14:

Please bid as specified.

Question 15:

Is it the design intent that each rock anchor provide enough pullout resistance within the rock anchor free length to resist the 113 kip max design load? Due to overlapping rock cones with the 7'x 6' grid anchor spacing, a rock column length of about 32' is needed to provide a factor of safety of 2 against rock cone pullout for every anchor.

The Technical Portion due July 20 will require the project technical approach as indicated in Factor 3: Organizational / Technical Approach. Depending on the scenario chosen it will affect scheduling, material/equipment delivery and management, labor management, cost management, site security, documentation and quality control. To provide the most competitive costs scenario, we will not know unit the after July 20 when the pricing is due from the subcontractor trades.

We are requesting the Technical Portion of the proposal be due at the same time as the Pricing Proposals due on July 29 so we can provide the best competitive approach to the rock removal scope.

Government Response 17:

The Government understands and acknowledges the concern. The Government encourages Offerors to write their Technical Proposal in a way which reflects the Offeror's best understanding at the time the Technical Proposal is submitted. When writing the Technical Proposal, the Offeror may avoid imposing unnecessary restrictions on the Offeror's ability to submit the best possible Price Proposal nine days later.

The Government is not considering extending either deadline at this time.

Question 18:

Please provide a basis of design for the precast concrete access vault.

Government Response 18:

The design of the access vault can be found on Sheets C-503 thru C-506 Question 19:

It is not clear if this demolition will be by the GC, or by others. Note 13 on CD101 says "TBR" (To Be Removed). Note 11 on CD102 says "TBR BY OTHERS". Are Demolition of these Structures in the General Contractors scope of work?

Government Response 30:

Concur Quarters 8 is brick. Demolition of Quarters 5, 6, 7 and 8 is to be performed by the Contractor. Note 11 on CD102 was corrected in Amendment 7.

Question 31:

Reference Division 2. There are Asbestos/ Lead Surveys (with Bulk Sampling) in Div. 2 for Quarters 5, 6 & 7. Nothing for Quarters 8, which is also scheduled to be demolished. Are we to conclude there are no Hazmats contained in Quarters 8? If not, kindly provide an Asbestos/ Lead Survey for Quarters 8.

Government Response 31:

A HazMat report is not available for Quarters 8. Contractor is to assume similar HazMat conditions for Quarters 8 as has been reported for Quarters 7.

Question 32:

The specs show 25 seismograph monitoring locations but they do not indicate how long the seismographs need to be onsite. We will need that information to determine pricing.

Government Response 32:

Seismographs will need to be in place for the duration of rock blasting and excavation and any activities that could potentially cause vibrations above the specified threshold value.

Question 33:

What are the blast rating and requirements for aluminum systems?

Government Response 33:

If this comment is referring the aluminum framed window and doors systems there are no blast ratings and blast requirements.

Question 34:

What is the STC rating desired for at the interior aluminum systems?

Government Response 34:

The aluminum curtainwall system (08.44.00) is specified to have an STC of not less than

40. Aluminum windows are based on Kawneer Trifab which has an 38 STC when glazed with an insulated glass unit.

The GL-11 glass that is called out for the interior windows is nominal 1/4" glass (1/8" glass + interlayer + 1/8" glass) to achieve an STC of 35. The STC of the entire assembly will vary depending on size, number of divisions, etc.

Question 35:

Drawing I-103D does not label the room located west of Elec EC-308 and south of room EC-310, photonics supports.

Please provide a label and finish designations for this room.

Government Response 35:

This is unfinished/unoccupied space.

Question 36:

Please provide clarification regarding CLIN's 007 & 008. Drawing A745.A was revised in Amendment #06, showing that add alt #02 (CLIN 007) affects the stair landings/treads associated with add alternate #03. CLIN 007 requests the cost difference between providing terrazzo as the finished stair product for the treads and landings, in lieu of the polished concrete. However this CLIN would be affected if CLIN 008 is accepted, as it adds another floor to this stair.

Please clarify if CLIN 007 should include the terrazzo pricing from floors 1 through 4, or just the base bid floors 1 through 3. If the 4th floor is required, it should be priced as a sub-CLIN, that can only be accepted if CLIN 008 is accepted.

Government Response 36:

The Government understands and acknowledges the concern, but the direction is to bid as shown on the drawings.

If both Optional CLINs 0007 & 0008 are exercised, the stair will be terrazzo up until and including the 3rd floor landing, and above the 3rd floor landing will be sealed concrete floor.

Question 37:

Please confirm stairs are to receive Terrazzo treads only at stair #3, tread & risers at stair #4, no TZ finish at stair 1.

Government Response 37:

Confirmed. See base bid documents for terrazzo finish at Stair #3. See Add Alternate #02 "Terrazzo Throughout North Stair" for terrazzo extents at stair #4.

Question 38:

Is refinishing of any existing terrazzo in the Mahan Building included?

Government Response 38:

Refinishing of existing finishes in the Mahan Building would only be required if disturbed or damaged by new work and all new work to match existing unless noted otherwise. Refer to Sheets A112L.A and A113L.A for clarification on extent of new finishes in Amendment #2.

Question 39:

Spec Section 230000 page 17 2.9.1.4-Duct Pressure Classifications and Construction Paragraph a, Item #1 says supply ducts between AHU and Fire or Smoke Dampers is 10 inch WG. There aren't any Smoke Dampers shown and some systems don't have any Fire/Fire Smoke dampers in them and others have them coming out of the shafts or somewhere downstream. For clarification, please indicate or summarize exactly where the 10 WG duct is required.

Government Response 39:

This pressure class requirement applies to ductwork between the respective AHU discharge and the first fire damper, or combination fire/smoke damper, indicated in the respective mains. Refer to the interstitial space ductwork plans (Drawings MH-114 - Sectors D through J) for damper locations.

Question 40:

Duct pressure classifications differ from spec section 230000 and drawing M-003-i.e. the specifications call for the supply duct between the AHU and Air Volume Control Box to be 6 inch WG. Drawing M-003 Note #8 says supply duct to Air Volume Control Boxes is 6 inch WG when the external static pressures are 3 to 5 inches which would only apply to AHU-4. All other AHU's would be either 3" or 4" WG. Please clarify which specification to follow.

Government Response 40:

The more stringent criteria shall apply. Follow specification 23 30 00. All supply ductwork between the AHUs and Air Volume Control Boxes shall be 6" w.g. (minimum).

Question 41:

On drawing M-003 Note #33 says Exposed duct in all areas shall be double wall. Is this required for this project? If so, does this apply to MH-111D-Exposed duct in loading dock and AHU-1 return and drawing M-112D-AHU-1 exposed supply and return duct?

On drawing MH-111F is the exposed duct in High End Fabrications and the electrical rooms double wall? On drawings MH-111E, MH-111F, MH-111J, MH-112E and MH-112F much of the duct is above a Strut Grid Ceiling System-Is this duct considered exposed and required to be double wall?

Government Response 41:

Yes, double-wall ductwork is required for this project. It is intended to protect ductwork insulation in occupied spaces where it may be prone to damage.

Yes, this applies to exposed duct (requiring insulation) in the loading dock on Drawing MH-111D.

Yes, this applies to exposed duct (requiring insulation) associated with AHU-1 (supply and return) on Drawing MH- 112D.

No, this does not apply to ductwork above the unistrut grid ceiling in High End Fabrication and ductwork in the electrical rooms on Drawing MH-111F unless specifically stated otherwise.

No, this does not apply to ductwork above the unistrut grid ceiling on drawings MH-111E, MH-111F, MH-111J, MH- 112E and MH-112F unless specifically stated otherwise.

Question 42:

On drawing M-003 Note #53 Item I says the first 5' of duct after the Volume Control Boxes is to be double wall. Is this a requirement on this project?

Government Response 42:

Yes, this is a project requirement for sound attenuation. Refer also to detail E5/M503.

Question 43:

Spec section 230000 2.9.1.4-Duct Pressure Classifications and Construction Paragraph a, Item #5 says dust collection supply ducts between the dust collector outlet and the explosion isolation valve is 22 inch WG positive. On drawing M-601 the dust collector schedule note #5 indicates there will be isolation valves on DC-4 and 5. Please indicate where the valves are to be located in the ductwork so the extent of the 22 WG duct can be determined. Just to verify, are these the only 2 dust collectors that will require isolation valves and 22 WG duct?

Government Response 43:

Refer to ductwork plans MH-111F and M403 for explosion isolation valve locations. Yes, only dust collectors DC-4 & DC-5 have explosion isolation valves and 22" w.g. ductwork.

Question 44:

Drawing MS108.A has an add Alternate #4 that increases the size of the Chiller and the Chilled Water and Condenser Water Pumps. Should the size of the Cooling Tower be increased too? Please provide a schedule if required.

Government Response 44:

The size of the cooling tower CT-7 is not changed as a result of Alternate #4.

Question 45:

There are clocks shown on the drawings but there is no spec. section. Please advise.

Government Response 45:

CLOCK SYSTEM SHALL BE COMPATIBLE WITH WEST POINTS STANDARD CLOCK

SYSTEM FROM SAPLING AS PER T-606.

Question 46:
