Answer: The concentrate tank may contain approximately 800 gallons.

38) Our understanding of Sections 01 11 00 Summary of Work and 01 14 00 Work Restrictions and will require us to consolidate onsite construction activities as much as possible to limit occupant displacement. Once interior facility modifications begin the facility will be unoccupied and under contractor control. Is that correct?

Answer: Yes. The intent is for the contractor to mobilize and stage materials in a manner that prolongs occupancy before displacing occupants for construction activities, transferring the building to contractor control.

39) In 01 57 19 Section 3.16.1 includes a substantial analytical list for testing soils (GRO, DRO, RRO, VOC, SVOC, PAH, PCB, pesticides, PFAS, and RCRA metals), however, in 02 61 13 Section 3.4 only PFOS & PFOA are noted as chemical parameters. Please clarify if a wider chemical list should be used for handling the 250cy noted in 02 61 13 spec.

Answer: 01 57 19 Section 3.16.1 refers to procedures for INADVERTENT DISCOVERY OF PETROLEUM- CONTAMINATED SOIL OR HAZARDOUS WASTES. At this time, the only known potential contaminants are PFAS and PFOA, however there is always the possibility that other contaminants may be encountered. Should the inadvertent discovery occur, then procedures listed in that section should be followed.

02 61 13 Section 3.4 is required for this excavation on this project.

40) Should sampling for perfluoroalkyl substances (PFAS) be done by Method 1633 or Method 537?

Answer: Method 1633

41) In 01 57 19 Section 3.16 mentions PID screening as well as 02 61 13 Section 3.4 however there is no 31 09 20 00 29 specification. Is it correct that field screening with a PID during soil excavation is not required?

Answer: Correct, no PID field screening is required during excavation

42) General Note 6 on A-0.1 – Please provide referenced roofing report. Requesting Government to quantify amount of roofing repairs that will be required or set up an additional site visit to allow contractors to assess the existing conditions prior to bidding.

Answer: See attached roof report.

43) Due to the delegated design elements for building automation, seismic restraints, fall arrest system, etc., we respectfully request more time to engage with designers for concept drawings to allow subcontractors to provide accurate pricing. A minimum of 2 weeks to a maximum of 4 weeks would benefit the proposal process.

Answer: This solicitation amendment includes an extension.

44) Are as-built drawings of B1171 available? Elevation information is particularly important related to the structure, platforms etc.

Answer: See Answer to Question #18

45) Existing B1171 floor slab elevation is shown as 543.3'. Spec section 01 01 00, paragraph 1.3.2, Bid Option 2 states the new fire main water loop is to be 10' below the apron and match installation of the new utiliducts. Are soil bores available to provide ground water depth? (Reference DWG C-1.1)

Answer: Soil borings only went to 5’ below grade and did not show any groundwater in the test borings. No other information is available.

46) Given the top of water line under the apron is 10', is a sleeve/casing require? If so, what diameter, and what type of joints are required for the water piping? (Reference DWG C-1.1)

Answer: A sleeve will be required to house the insulated water line. The water line is nominal 8", with 2" of insulation around it. Outer pipe sleeve should be 14" min diameter to allow for pipe to be inside the sleeve. A minimum of 10 ft joints are acceptable.

47) Please confirm the jack-n-bore section of fire main loop does not require heat trace. (Reference DWG C-1.1)

Answer: Provide heat tape on the jack and bore section, with 2" insulation around the pipe. Provide pull points at each end and J boxes in utilidor for replacing heat tape if needed in the future.

48) If the under-apron section of pipe is in direct contact with earth, is a corrosion protection system such as sacrificial anodes, required? (Reference DWG C-1.1)

Answer: Anodes shall be put in if ductile iron pipe is used for direct contact with soil. See question 47 for additional details on pipe.

49) What are the existing swale inverts on the north (plan left) and south (plan right) sides of B1171? (Reference

DWG C-1.1)

Answer: See attached revised drawing C-1.1 with elevations taken from the sheet C3.1 from the original design/construction drawings.

50) Given the anticipated 11' - 12' depth of excavation (below 543.3') what is the footing structure of B1171?

(required to prevent undermining) (Reference DWG C-1.1)

Answer: Refer As-Built for detail. Due to Alaska climate, footing is primarily supported below the frost line. All perimeter wall is supported on Frost wall below grade and on continuous footing. All steel column is supported on concrete pedestals and on spread footing. All steel braced frame column footing is connected with concrete grade beam and footing. The area of influence from bottom of footer is a 1:1 slope. The Utilidor edge is approximately 14 feet away from the edge of the existing structure. Bottom of footers are a minimum of 6’ below finished floor. At a 1:1 influence, the 12’ excavation depth will not impact the area of influence of the existing footers.

51) Specifications state, "B1171 will remain in operation by the occupants to the greatest extent practicable . . . " It is unlikely any contractor would choose to work over an aircraft parked in the hangar; is this prohibited? If suspected service operations require use of the floor to work on jets, would the Gov't provide a quantity of times and distinct durations the hangar bay will be unavailable to the Contractor? (Reference 01 30 00, 1.1.b)

Answer: Contractor work in the hangar is generally incompatible with aircraft maintenance work. See answer to Question 38.

52) Are five sets of color boards truly required for this project? According to the submittal register following 01 45 00, each specification section calling for finishes requires samples. This paragraph is usually reserved for Design- Build proposals. (Reference 01 30 00, 1.3)

Answer: 5 sets of color boards are not necessary. Digital samples indicating color and finish are acceptable for submittal review.

53) Please confirm as-built CAD files, as well as the solicitation's design drawings, will be made available after award for Contractor use in developing shop drawings and new Record Drawings? (Reference 01 78 00, 1.3)

Answer: Hard copy record drawings are available for review. .dwg files from the design can be made available after award. .dwg files from original construction can be made available after award, however, they may not fully reflect the as-built or current facility configuration, and the contractor must verify accuracy of any record information provided.

54) Is the Contractor able to disregard the "Design Phase" commissioning activities? (Reference 01 91 00, 3.1)

Answer: Yes.

55) The Division 02 specifications insinuate a large range of known hazardous materials/wastes are in B1171.

Since it was constructed in ~1998, it's unlikely ACM, LPB and PCBs were used in construction originally. Is the Contractor to complete a full sampling / survey of these HAZMATs under scope of this project? What criteria is to be followed? (Reference Div 02 Spec)

Answer: Per specifications, the contractor is required to provide a complete hazardous waste management plan for approval by the Government.

56) If hazardous materials/waste are found in the sampling / survey, how is the Government going to work with the contractor for abatement and disposal? (Reference Div 02 Spec)

Answer: The Government does not anticipate the contractor will encounter any hazardous materials/waste.

However, if any are discovered, the contractor shall adhere to the instructions in FAR Clause 52.236-2, Differing Site Conditions.

57) Although some sitework and minor excavation occurs under the base bid, the drawings and specifications are unclear as to what activities are required detection of possible contamination, or is the site presumed clean?

(Reference 02 61 13)

Answer: See answer to Question #3.

58) If option 2 is not awarded, will a simple ESCP with field screening be acceptable in lieu of a unified QAPP?

(Reference 02 61 13, 1.3.2)

Answer: If option 2 is not awarded, all work is still subject to environmental requirements listed elsewhere in the specs. A site specific sampling and analysis plan is required for this project for any excavation because it is in the buffer of a PFAS contaminated site.

59) Please confirm a UFP-QAPP is not required for this project. (Reference 02 61 13, 1.3.2.)

Answer: All work is still subject to environmental requirements listed elsewhere in the specs. A site-specific sampling and analysis plan is required for this project for any excavation because it is in the buffer of a PFAS contaminated site.

60) The pricing schedule following the SF 1442 does not include any line items for disposal of varying categories of hazardous waste, nor does provide anticipated quantities. Is Specification 02 81 00 included only for the purpose of negotiating disposal costs should contamination be discovered? Depending on the contaminants, disposal costs vary widely, and unknown quantities prevent contractors from assessing cost impacts at this time. (Reference 02 81 00)

Answer: See answer to Question #56.

61) The fire pump specification, para 2.2 states the fire pump shall deliver 150% of rated flow (2,500 gpm) at 65% of the rated pressure (165psi). Please confirm this means at the Preliminary and Final testing the pump is to discharge 3,750 gpm @ 107.2 psi. Is Eielson's Water Treatment Plant able to produce this level of output? What is the volume of the cistern? (Reference Spec 21 30 00)
