Please clarify what quantities, for the work specified in Subpart 1.1, that the Contractors are to include in their bid. Additionally, will the Government be adding unit priced items to the bid pricing schedule to address this requirement?

36.

A review of the “Soils/Foundation Notes” on Sheet Number S-001 reveals that the Government has concerns over the suitability of the existing soils materials below the building footprint and throughout the project site.

Soils/Foundation Note 6 on Sheet Number S-001 states, “Stripping and undercutting shall extend a minimum of 5 feet beyond the building perimeter and the depth shall be as determined by the Geotechnical Engineer.” Additionally, Note 9 states, “After inspection of the subgrade, structural fill material shall be placed in lifts between 6 and 12 inches.

1) Please clarify what depth of stripping and undercutting and replacement with compacted structural fill (below the building footprint and extending 5 feet beyond the building perimeter), if any, the Contractors are to assume and include in their bids. This is a potential substantial cost that the Contractors need to understand what quantity, if any, to include in their bids.

Soils/Foundation Note 7 on Sheet Number S-001 states, “After stripping the site but prior to placing fill the site shall be compacted. Any areas of significant deflection during compaction may be disked, dried, and re-compacted if weather permits, or removed and replaced with engineered fill.” Note 7 continues by requiring the identification of soft or unstable areas (during proof-rolling) and subsequent remediation procedures for “soft areas of subgrade that deflect more than 1 inch or show permanent deformation greater than 1 inch.” Additionally, Note 9 states, “After inspection of the subgrade, structural fill material shall be placed in lifts between 6 and 12 inches.

2) Please clarify what volume (depth and area) of undercutting and replacement with compacted engineered fill (of the site), if any, the Contractors are to assume and include in their bids. This is a potential substantial cost that the Contractors need to understand what quantity, if any, to include in their bids.

Note 10 states, “The Geotechnical Engineer shall provide recommendations for suitable types of engineered fill. Where unsuitable soils are encountered at the base of the foundations, soil correction should consist of additional excavation to remove the unsuitable soils to a depth determined by the Geotechnical Engineer. These over excavations shall be filled with engineered fill as given in Note 9. Alternatively a lean concrete with a minimum compressive strength of 500 psi can be used to fill the over-excavation to the bottom of the foundation.”

3) Please clarify what volume of removal of unsuitable soils and replacement with compacted engineered fill or lean concrete (below the base of foundations), if any, the Contractors are to assume and include in their bids. This is a potential substantial cost that the Contractors need to understand what quantity, if any, to include in their bids.

Undercut amount and soil characteristics to be determined by Contractor from information provided in contract documents and the geotechnical report for the project.

Geotechnical report will be provided for use and review.

Government is considering this pay item as a Lump Sum.

Subpart 1.3d “Criteria for Bidding” of Section 31 00 00 states, “Material character is indicated by the boring logs.”

According to the Site Characterization Report included in Section 02 61 13, Boring Numbers AA-MW-1 and AA_MW-2 indicate that the first approximately five feet (5’) consists of silty sand (SM), a combination of fill and silty sand (SM), clayey sand (SC), and lean clay (CL).

Poorly graded sand (SP) begins at a depth of approximately five feet (5’).

Boring Number AA-MW-3 indicates that the first approximately five feet (5’) consists of silty sand (SM), a combination of fill and clayey sand (SC), silt (ML), and lean clay (CL). Poorly grade sand (SP) begins at a depth of approximately five feet (5’).

Boring Numbers AA-MW-4 and AA-MW-5 indicate that the first approximately five feet (5’) consists of silty sand (SM), a combination of fill and silty sand (SM), and a combination of fill and clayey sand (SC). Poorly grade sand (SP) begins at a depth of approximately five feet (5’).

Subpart 1.5.1 “Satisfactory Materials” of Section 31 00 00 states, “Satisfactory materials comprise any materials classified by ASTM D2487 as GW, GP, GM, GP-GM, GW-GM, GC, GP-

GC, GM-GC, SW, SP.”

Subpart 1.5.2 “Unsatisfactory Materials” of Section 31 00 00 states, “Materials which do not comply with the requirements for satisfactory materials are unsatisfactory.”

According to the boring logs and Subpart 1.5.1, “Satisfactory Materials” are not present until approximately five feet (5’) below existing finish grade and, therefore, according to Subpart 1.5.2, the first five feet below finish grade would be considered “Unsatisfactory Materials.”

Subparts 3.7 and 3.7.1 “Ground Surface Preparation, General Requirements” of Section 31 00 00 states, “Remove and replace unsatisfactory material with satisfactory materials, as directed by the Contracting Officer, in surfaces to receive fill or in excavated areas.”

Subparts 3.13 and 3.13.2 “Subgrade Preparation, Construction” of Section 31 00 00 states, “Remove soft of otherwise unsatisfactory material and replace with satisfactory excavated material or other approved material as directed.”

4) Please clarify whether or not it is the Government’s intent that the Contractor is to consider the first approximately five feet (5’) of the existing soils to be “Unsatisfactory Material” and whether or not the Contractors are to include the costs in their bids to remove (undercut) and dispose of this existing material (“Unsatisfactory Material”) and replace with selected fill (“Satisfactory Material”) throughout the project site. This is a substantial cost that the Contractors need to know whether or not to include in their bid amounts.

37.

Soils/Foundation Note 1 on Sheet Number S-001 states, “Foundation recommendations are based on the geotechnical report prepared by Gestra dated September 10, 2020 . . .”

Subpart 1.6 of Section 31 00 00 states, “Subsurface soil boring logs are available upon request. The subsoil investigation report and samples of materials taken from subsurface investigations may be examined at the contractor’s request.”

Geotechnical report will be provided for use and review.

Please provide a copy of the geotechnical report prepared by Gestra dated September 10, 2022, as well as any other pertinent subsurface soil boring logs and subsoil investigation reports.

38.

Subpart 3.2.4 of Section 31 00 00 states, “The water level encountered during subgrade investigations was approximately 4.5 feet. If ground water is encountered, treatment for PFAS may be required.”

Please clarify if the Contractor is to include costs in its bid for the potential treatment for PFAS (of encountered ground water) that “may be required,” or if the Contractor should assume that a modification will be issued if treatment for PFAS (of encountered ground water) is actually required.

If the Government intends the Contractor to include costs in its bid for the potential treatment for PFAS (of encountered ground water), please clarify what quantity of treatment for PFAS (of encountered ground water) the Contractor is to assume in its bid.

This is a potential substantial cost that the Contractors need to understand what quantity, if any, to include in their bids.

Contractor should not include costs for environmental remediation associated with PFAS-contaminated groundwater as part of the base bid. The Environmental Materials Management Plan (to be provided) states soil will be stock piled/treated on base at the 115 FW. If dewatering is required the permit won't has PFAS in it. Therefore anything deviation from the plan would be part of a contract action in the future.

39.

Subpart 1.3 Description of Work of Section 02 61 13 Excavation and Handling of Contaminated Material states, “The work consists of excavation and temporary storage of approximately 25 cubic yards of contaminated material, including contaminated soil . . .”

Please confirm our interpretation of the contract documents; specifically, that the Contractor is only required to assume and include a total of 25 cubic yards of contaminated material (contaminated soil) removal (excavation and temporary storage), hauling, disposal, and replacement (with suitable backfill material) in its bid for this project, and that, if additional contaminated material is discovered, the Government will issue a modification for additional contaminated soil removal, handling, hauling, disposal, and replacement with select fill.

Provide pricing as Lump Sum included in the base bid.

40.

Subpart 1.5.9 Surface Smoothness of Section 32 12 16.16 of the specifications specifies that “Straightedge Testing” shall be performed on the finished surfaces of the pavements.

However, it appears that a reference to the “profilograph” method was erroneously left in Subpart 1.5.9.2 Testing Method.

According to Unified Facilities Guide Specifications (UFGS), the profilograph method cannot be used for paving lanes less than 0.25 miles in length and states to “use the straightedge method for transverse testing, for longitudinal testing where the length of each pavement lane is less than 0.25 miles, and at the ends of the paving limits for the project.”

Please confirm that only straightedge testing will be required for surface smoothness testing.

Correct. Only straightedge testing will be required. The profilograph has been omitted. Contract documents have been updated to remove reference to profilograph from Specification Section 32 12 16.16. This has been updated as part of Addendum No. 02, dated 8 June 2022. Please see Addendum No. 02, Specification Section 32 12 16.16.

Subparts 1.1.2 and 1.1.2.1 Payment, Excavation and Transportation of Section 02 61 13 Excavation and Handling of Contaminated Material states, “Compensation for excavation and onsite transportation of contaminated material will be paid as a unit cost. This unit cost shall include any other items incidental to excavation and handling not defined as having a specific unit cost.”

Additionally, Subparts 1.1.2 and 1.1.2.2 Payment, Backfilling of Section 02 61 13 states, “Compensation for backfill soil, transportation of backfill, backfill soil conditioning, backfilling, compaction, and geotechnical testing will be paid as a single unit cost.”

Further, Subparts 1.1.2 and 1.1.2.3 Payment, Stockpiling of Section 02 61 13 states, “Compensation for construction of stockpile areas will be paid for as a unit cost. This unit cost shall include all aspects of grading, preparation, handling, placement, maintenance, removal, treatment, and disposal of stockpile cover materials and liner materials and all other items incidental to construction of stockpile.”

The bid pricing schedule does not include any unit priced items as stated in Subparts 1.1.2 through 1.1.2.3 of Section 02 61 13. Will the Government be adding unit priced items to the bid pricing schedule to address this requirement?

It is the Government's intent to provide this item as Lump Sum in the base bid.

Item 11 on the Standard Form 1442 and Contract Clause 52.211-10 states that the contract performance duration is only 550 calendar days (approximately 18 months). We are requesting that the Government please consider increasing the duration by 12 months for the reasons discussed below.

The bid due date is currently 15 June 2022 and the Government is requiring an acceptance period of 180 calendar days. This means that the contract will likely be awarded during, or just prior to, the winter season. The winter weather conditions will prohibit, or greatly limit, the Contractor from performing many of the major earthwork activities that must be performed to prepare the project site for construction of the new concrete building foundations. The Contractor will likely not be able to make substantial progress on the major earthwork and concrete foundations activities until Spring of 2023, unless substantial costs are expended utilizing ground thaw provisions and winter-concrete provisions; both of which will only substantially increase the overall price of the project for the Government.

Also, before the earthwork activities can begin, the Contractor has hazardous material abatement work to perform, as well as major demolition of the entire existing Building 414;

both of which will require substantial time to perform.

As the Government is aware, the Contractors are also still faced with long lead-times for certain key building materials, such as structural steel, steel roof deck, insulated metal wall panels, roof deck insulation, etc. Extended durations to fabricate and delivery these items

Contracts period of performance WILL NOT be changed.

directly impacts the Contractor’s ability to construct the building structure and ‘dry in’ the building envelope to allow the interior work to progress.

Additionally, the development of a concrete mix design required by Section 32 13 14.13 “Concrete Paving for Airfields and Other Heavy Duty Pavements” typically requires approximately 12 months in order to complete the proportioning studies and prepare the mix design for the Government 30-day review and approval, which is then followed by key, time-consuming quality control activities before production paving can begin. It will be a challenge to obtain an approved mix design and construct the airfield concrete paving for the new PCC pavement (apron area) and three hangar floor slabs before the onset of the second winter season in late 2023; as it is not possible at all to expedite the concrete mix design process due to the strict prescriptive requirements in Section 32 13 14.13. Also, due to the stringent weather and environmental requirements contained within Section 32 13 14.13, the Contractor will likely have to wait until the Spring season of 2024 to construct the airfield concrete paving for the new PCC Pavement and three hangar floor slabs, or be faced with substantial costs for utilizing ground thaw provisions and winter-concrete provisions;

both of which will only substantially increase the overall price of the project for the Government. It should be noted that there is a substantial amount of work that still must be performed within the hangar bays after the hangar floor slabs are constructed.

The specifications also include time-consuming start-up and testing requirements for this project, which are typical for a Federal Government project of this size and complexity (i.e., fire suppression, plumbing, mechanical, building automation, electrical, fire alarm and mass notification, and security system start-ups; performance verification testing (PVT); testing, adjusting, and balancing (TAB); total building commissioning (both pre-FPT and FPT) of the numerous systems required by Section 01 91 00.15 10; and both the preliminary and final testing requirements for the fire suppression systems and fire alarm and mass notification system). Also taking into consideration the items discussed above, it will be a challenge to complete all of the work and the start-up and testing requirements within the only 550 calendar day duration due to the prescriptive sequencing and scheduling requirements for these tests contained throughout the specifications.

As mentioned above, we are requesting that the Government please consider increasing the duration by 12 months for these reasons. If the contract duration is maintained at only 550 calendar days, it will require extensive expediting fees and a considerable amount of overtime to complete the contract within the 550 calendar days. This will simply result in increased costs to the Government.

44.

Will the Government please provide the bidders with copies of all available as-built drawings for existing Building 414?

As-built drawings can be provided to successful bidder.

Sheet Number C-301 shows two parallel light gray dotted lines routed from the Existing Building 414, continuing towards the plan Northwest, and then continuing towards the plan North. Sheet Number C-401 reflects the same two parallel lines. During the pre-bid site visit, there was evidence of saw cutting and sealant (of some unknown type) within the existing concrete and asphalt pavements following this approximate route. Since the existing concrete and asphalt pavements are indicated to be demolished, it is assumed that whatever this item is will also be demolished with the pavement.

Will the Government please clarify what these two parallel lines represent?

Please confirm our interpretation of the contract drawings; specifically, that the Contractor will have no responsibility to replace whatever these two lines represent.

Correct. These are existing fiber optic lines with backer rod and sealant. This will be removed at any location where pavement is indicated to be removed. Replacement is not required.

50.

Slab Plan Note 1 on Sheet Numbers SB105 and SB106 states, “11” Concrete Pavement (Flex Strength = 650 PSI at 90 Days) Reinf w/ #4 at 8” OC EW . . .” This note applies to the Weapons Training 101, Fuel Cell 119, and Wash Bay 128.

Will the Government please confirm that Section 03 30 00 Cast-In-Place Concrete (not Section 32 13 14.13 Concrete Paving for Airfields and Other Heavy Duty Pavements) is the specification section applicable to the concrete pavement work in the Weapons Training 101, Fuel Cell 119, and Wash Bay 128?

Confirmed. Specification Section 03 30 00 contains the applicable requirements for 11-inch-thick, concrete slabs within Weapons Training, Room 101; Fuel Cell, Room 119;

and Wash Bay, Room 128.

51.

Please confirm our interpretation of the specifications; specifically, that the Contractor is only required to assume the quantities of “Non-friable Category I and Category II ACM” and “RACM” listed on Pages 2 and 3 of 5 of the Ayres letter dated 29 July 2020, which is included as the “02 61 13 _02 Final Asbestos Report (072920)” in Volume 1 of the specifications, are required to be abated and that any additional asbestos abatement will be considered a change to the contract.

Asbestos removal will be Lump Sum as part of the Base Bid based upon the study.

52.

Sheets A-201 & A-202 Building Elevations refer to “color #1” and “color #2” for the vertical and horizonal insulated metal wall panels and well as split-faced “colored” CMU. However, no color schedule or reference to any of the exterior finishes can be located. Please provide the exterior finish schedule.

Contract documents have been updated to provide exterior finish/color information. This has been updated as part of Addendum No. 02, dated 8 June 2022. Please see Addendum No. 02, Specification Section 09 06 00.

Subpart 3.6 Test Section of Section 32 12 15.13 Asphalt Paving for Airfields states, “Prior to full production, place a test section for each JMF used. Construct a test section 250 to 500 feet long and two paver passes wide with a longitudinal cold joint.”

There appears to be a minimal amount of airfield asphalt pavement on this project for which Section 32 12 15.13 is applicable. There is no area of new airfield asphalt paving that is 250 to 500 feet long. Additionally, two paver passes wide would complete a substantial majority, if not all, of the new airfield asphalt paving required for the entire project.

Will the Government please consider waving the requirement for the “Test Section” associated with the asphalt paving for airfields?

15.13. This has been updated as part of Addendum No. 02, dated 8 June 2022. Please see Addendum No. 02, Specification Section 32 12 15.13.

54.

Section 32 13 14.13 Concrete Paving for Airfields and Other Heavy Duty Pavements of the specifications includes requirements for a project-specific mix design, with the Contractor performing deleterious testing and alkali-silica reactivity (ASR) testing of aggregates, proportioning studies, trial mixture studies, and uniformity testing for its proposed mix design. These tests amount to costs in excess of $50,000 and, for a relatively small quantity of airfield pavement (PCC Pavement) and hangar floor slab pavement, it would be much more cost-effective if the Government were to provide bidders with an option to use a previously-approved mix design(s) that has been successfully utilized on other projects at Truax Field ANGB. It is understood that the Government requires a quality product for the concrete paving and we believe this would be a more cost-effective way to achieve that end result.

Additionally, Subpart 1.4.4 “Preconstruction Testing of Materials” of Section 32 13 14.13 states, “All sampling and testing is required to be performed” and “Materials are not allowed to be used until notice of acceptance has been given. Additional payment or extension of time due to failure of any material to meet project requirements, or for any additional sampling or testing required is not allowed.” Subpart 1.4.4.1 “Aggregates” of Section 32 13 14.13 states, “Perform all aggregate tests no earlier than 120 days prior to contract award.” Based on experience on past projects and the required testing sequence for aggregate testing (ASR / deleterious testing), proportioning study, trial mixes (with 90-day breaks), uniformity testing, and Government-approvals for each, the total time to perform pre-construction testing is approximately 12 months. Due to the extremely short contract duration (550 calendar days), it will be extremely difficult to perform all preconstruction testing of materials, proportioning studies, trial mixture studies, and uniformity testing and leave adequate time for construction of the airfield pavement and the subsequent construction activities.

A mix design will be provided upon award by the Base to be utilized for the PCC apron paving.

Will the Government please provide the mix design company and mix design number of an acceptable previously-approved mix design(s) that will be acceptable for the Contractor to utilize for the project? Note, due to the limited size of paved areas, it is anticipated most, if not all, of the concrete paving will be performed by fixed forms; therefore, please provide previously-approved mix design(s) for slip-form and fixed form paving methods.

55.

Please confirm that the CQC System Manager specified by Subpart 1.4.1a of Section 32 13

14.13 Concrete Paving for Airfields and Other Heavy Duty Pavements of the specifications can be the same individual as the CQC System Manager specified by Subpart 3.4.2 of Section 01 45 00.00 10 of the specifications.

Correct. This may be the same individual.

56.

Please confirm that the Airfield Asphalt Pavement QC Manager specified by Subpart 1.5a of Section 32 12 15.13 Asphalt Paving for Airfields of the specifications can be the same individual as the CQC System Manager specified by Subpart 3.4.2 of Section 01 45 00.00 10 of the specifications.

Correct. This may be the same individual.

Subpart 1.4.6.1 “Pilot Lane (Test Section)” and Subpart 1.4.6.2 “Fill-In Lane (Test Section)” of Section 32 13 14.13 Concrete Paving for Airfields and Other Heavy Duty Pavements of the specifications require the Contractor to construct a pilot lane test section of at least 200 feet long and a fill-in lane test section 400 feet long as part of the production paving area. Due to the relatively small size of the project, this is not possible.

Contract documents have been updated to remove requirements for test section from Specification Section 32 13

14.13. This has been updated as part of Addendum No. 02, dated 8 June 2022. Please see Addendum No. 02, Specification Section 32 13 14.13.

58.

As it relates to the pilot lane test section, there are no lanes that are 200 feet long. Also, a 200-foot-long pilot lane test section would be approximately thirty percent (30%) of the entire area of PCC pavement required for the project.

As it relates to the fill-in lane test section, the project does not even contain 400 feet of production fill-in lanes that can utilize two adjacent existing lanes as forms. Also, 400 feet of fill-in lane test section would be another approximately sixty percent (60%) of the entire area of PCC pavement required for the project.

Collectively, the specified pilot and fill-in lane test sections would be greater than ninety percent (90%) of the entire area of PCC pavement required for the project.

Will the Government please revise the specifications to remove the requirements for the test sections (pilot lane and fill-in lane) given the small amount of concrete paving on the project? If the Government determines test section(s) are required, please provide reduced requirements consistent with the size of the paving scope and confirm that test section(s) may be part of the completed work if they meet specified requirements.
