RFI LOG as of 10 January 24.pdf

Q1. Do you need to be a Small Business to submit a proposal? We do not fall under the Small

Business Classifica on so we’d like to know if we can s ll submit a proposal or if we need to work with

Small Business.

A1. 1. This acquisi on is unrestricted meaning that all firms, including yours, with the 237310:

Highway, Street, and Bridge Construc on NAICS code are allowed to submit.

Q2. If we need to send our quote to a Small Business for them to submit, do you have an approved bidder’s list? We do not know the Small Businesses approved to submit bids on this project and would need their contact informa on.

A2. There is no approved bidders list or a group of prequalified contractors.

Q3. Is there a Schedule of Values showing the items and quan es on the project?

A3: Please refer to the schedule of value requirements in the Specifica ons. Normally a contractor submits their own schedule of values post award.

Q4. Is this a Lump Sum project or will the contractor be paid for the quan es completed?

A4. This is a lump sum contract with that allows for progress payments for conforming work based on the approved schedule of values.

Q5: We’ve had a couple Small Businesses reach out to us reques ng a quote, do they receive a discount rate that would lower their overall bid during the bid evalua on process? It doesn’t make sense to me why they’d want to manage this project on our behalf.

A5: Please be mindful that if the small business is a cer fied HUBZone (Historically Under‐

U lized Business Zone) there is a 10% price evalua on preference against large businesses if it bids as a prime contractor The clause at 52.219‐4 NOTICE OF PRICE EVALUATION PREFERENCE FOR HUBZONE

SMALL BUSINESS CONCERNS (OCT 2022) has the necessary informa on and s pula ons and is included in the solicita on. This clause is mandatory for all full and open compe on solicita ons per FAR

19.1309 and is not waiver able. A HUBZone business is a small business that has offices and a percentage of employees located within these Historically Under‐U lized Business Zones. These zones are in rural or urban areas that are rela vely impoverished as you can imagine.

Other than the Hub Zone preference there is no price discount for small business.

Q6. In the instruc ons to bidders’ sec on, it states that A Forma ed CD with all documents is to be submi ed with the bid. However, no men on of a CD is made in Sec on 00 10 00 where is discusses what cons tutes a complete bid package. So, is a CD required with bid submi al or not?

A6. The submission of a CD is part of the IFB instruc ons as paper copies of bids are cumbersome and the use of CDs makes processing bids faster. A complete bid package is as per Sec on

001000 for the purposes of providing a responsive bid. Thumb/USB drives are not allowed on Govt computers due to security concerns.

Q7. Can you provide an es mated dollar value for the SESC Permit Required by the contract?

Typically, a dollar value is given to the contractors to plug into our bid for these permits.

A7‐ In review of the plans it does not appear that more than 1 acre of land will be disturbed.

SESC measures will be required in and/or around any catch basons located on the construc on site.

While the cost should be minimal the awarded contractor is responsible for all permit fees in accordance with the FAR clause at 52.236‐7 Permits and Responsibili es.

Q8. In the SOW it states the contractor is responsible for funding and coordina ng addi onal security requirements to ensure adequate coverage during construc on. What cons tutes above normal security requirements and what is the cost for addi onal security forces?

A8. per DAFI 31‐101, para. 3.6.7., commercial vehicle inspec on (CVI) areas (commercial trucks) must be manned with two armed individuals at all mes while the in opera on.

Aggregate hourly cost for armed individual: $60/hour

Government vehicle not provided. Contractor required to provide vehicle for armed individual.

Q9. Can you confirm the grooving is called for on the new AC pavement only, from sta on 0+00 to sta on 57+00?

A9‐ Only new asphalt on the runway (not taxiways) will be grooved according to plans and specs from sta. 0+00 to 57+00.

Q10. Since the grooving is a ‘Post Runway Closure Task’, should we an cipate limited working hours for the grooving? If so, what are the working hours we should base our pricing on?

A10. ‐ The Runway will not be open prior to grooving and paint. An cipate regular working hours.

Q11. The primary millings dump loca on shown during the site visit is not what’s iden fied on plan sheet C101. Please update this sheet to iden fy the primary dump loca on for millings.

A11 ‐ The primary milling dump site is iden fied as Milling Deposit Area 5 on page C100. Milling

Deposit Areas 1 and 4, iden fied on page C101 may be used in the event of an emergency or overflow of

Area 5. Areas 1 and 4 fall within the muni on's quan ty – distance radius and will require coordina on with Muni ons Explosive Safety to be u lized.

Q12. How is the contractor directed to handle the millings once dropped at the millings deposit area?

Will the contractor be responsible for pu ng the millings in a pile? Will the millings need to be spread, graded, and compacted?

A12 ‐ See Pg. C100 – “Milling Deposit Area, Contractor responsible for maintenance of pile height and spreading millings. Milling deposit areas are accurate at plan genera on but may need to be reassessed a er project award based on Base SESC Permit requirements. Addi onal sites as needed for milling deposits will be provided by the ANG Base within 6 miles driving distance from the runway.”

Q13. The typical cross‐sec on details shown on C301 are misleading for a lump sum contract. First, the exis ng asphalt is labelled as 6”‐7” in thickness. Second, the contractor is told to mill full depth if less than 1” of asphalt remains over the cement stabiliza on. At the proposed milling depth of 6.25”, there will be Zero areas on the runway where 1” of asphalt is le over the cement stabilized base. Please clarify how many areas the contractor will be paving asphalt deeper than 6.25”. Is there a core log that can be provided that iden fy these areas?

A13 – Due to natural fluctua ons in pavement thicknesses during placement, it's impossible to know exact areas where thicknesses will be in excess of 6.25”. The contractor shall maintain the proposed grade on the contract documents, have a minimum 1” of exis ng asphalt pavement le in place, with a minimum of 6.25” overlay of asphalt. Historic data, borings, logs and drawings indicated differing thicknesses on the runway ranging from 6” to 9.5” thick. Contractor should assume 20% of the runway would need addi onal asphalt because the exis ng asphalt thickness is between 7.25” and 6.25” thick.

Q14. The specifica ons call for Cemen ous Mixing Plant for the Cement Stabilized Base, because these are small patches, not much quan ty/area, can the plant requirement be waived? Maybe blend the cement in place or use a different material all together?

A14 ‐ No. The CTB should be mixed in the mixing plant per specifica ons.

Q15. The detail for pavement repair on C602 indicates undercu ng a not less than 42”.

a. Is undercut to be included in the lump sum price or will it be handled on a unit price basis?

b. If it’s included in the lump sum price, do we base it on 42”?

c. If it needs to go beyond a 42” depth how is that paid for?

A15 – A. The full depth repair requirement is to cut to 42” below grade – this should be included in the lump sum bid; B, The base bid is for 42” from finished pavement eleva on; C, Q16. Regarding The pavement repair areas.

a. The borders shown on plans, are we to use that as the perimeter/border of each patch?

b. Is there only to be par al shoulder removal/replace in the patch areas per the plans?

c. Per C602, are we to start our excava on in 2’‐6” from the border line, or because the pavement being milled, do we start excava on at that border line?

A16 – a. border dimensions are provided on sheets C‐401 and C‐402, b. Full depth repair dimensions are provided on sheets C‐401 and C‐402, c. Excava on to be offset 2’6” from dimensions provided in the drawings.

Q17: Sheets C101 through C206 of the contract drawings indicate loca ons where “Soil Boring(s)” were performed. Will the Government please provide the bidders with a copy of the soil boring logs and any geotechnical inves ga ons and reports that are available that may be per nent to the project?

A17 ‐ N/A, boring logs are not relevant at this stage when the design is complete.

Q18: Subpart 1.6.9c of Sec on 03 30 00 of the specifica on’s states, “Contractor Quality Control: All sampling and tes ng must be performed by an approved, onsite, independent, accredited laboratory.

“Please clarify whether the Contractor is required to provide and maintain ONSITE validated tes ng laboratories, or if the Contractor is allowed to u lize offsite validated tes ng laboratories (which is more common for a project of this size and magnitude) during the performance of the contract. It would be very imprac cal and extremely costly to have an on‐site tes ng laboratory for this project.

A18 ‐ USACE cer fied off‐site lab is acceptable; however, the Contractor may opt to establish an on‐site lab that would be required to be cer fied by the USACE by the MTC at no cost to the

Government. Any delays due to an off‐site lab will be the responsibility of the Contractor.

Q.19: Subpart 3.2D of Sec on 01 52 13 of the specifica on’s states, “Loca on of all temporary structures shall be as directed by the Contrac ng Officer.”

Will the Government please clarify for the bidders the loca on that the Contractor and subcontractors will be able to u lize as a temporary office trailer and staging area? Addi onally, will the Government please clarify if, and what, u li es are available for temporary use in the designated area?

A19 ‐ There are no u li es available in the designated staging area. There is an area available across from Bldg. 825 (Medical Facility) on Jefferson Rd. to place an office trailer. The Contractor will be responsible to provide the drop, meter and all associated material, equipment, and licensed electrician for the electrical connec on. The Contractor will be billed $0.118 per Kilowa Hour.

Q20. Subpart 1.18A of Sec on 01 50 00 of the specifica on’s states, “Provide temporary parking areas to accommodate use of construc on personnel.” Will the Government please clarify for the bidders any exis ng parking lots/areas that the Contractor and subcontractors will be able to u lize as a temporary parking and/or clarify if the Contractor will be required to construct a temporary parking area?

A.20 ‐ A loca on for Contractor personnel parking will be provided. The Contractor will be responsible for busing/car‐pooling personnel to the runway.

Q21. Will the Government please clarify for the bidders whether or not the Contractor will be required to construct temporary chain‐link fencing around any areas u lized by the Contractor as a temporary office trailer and staging area?

A21 – Temporary fencing will not be required.

Q22: Will the Contractors and subcontractors be required to make payment for access badges in order to mely access Selfridge ANG Base on a daily basis?

A.22 All persons needing unescorted access to Selfridge ANGB will need to be ve ed and issued a pass for the dura on of the project. The Contractor will fill out a ve ng form to be processed by

Security Forces. If approved, a pass will be issued at the Visitor’s Centre at no cost to the Contractor or the individual receiving the pass. The pass will be returned to the Visitor’s Centre upon comple on of the project.

Q23: There is a note on Sheet C100 of the contract drawings that states, “Base escort required for all work performed within airfield limits. “Will the Government please clarify what, specifically, the applicable requirements are for the “base escort?”

For example:

1) Are the base escorts provided by the Government (at no cost to the Contractor) or by the Contractor?

2) Are base escorts required to be provided for each and every vehicle that enters the airfield limits, or can gate guards be sta oned at the entrance(s) to the airfield limits to control who enters and leaves the airfield limits?

A.23

1. SOW 1.a.xii. The Contractor will be responsible for providing Contractor Escorts for the dura on of the project. The Contractor Escorts will have to be trained and cer fied by Airfield Management for opera ng on an Ac ve Airfield.

2. Any individual without a SANGB issued line badge will be escorted at all mes on the airfield. Crews can be escorted by a Construc on Escort, but individuals will not have free movement on the airfield unescorted. Properly trained Contractor employees may be used at airfield gates to allow movement of construc on traffic. Designated and marked haul roads may be used with unescorted drivers as long as they have been ve ed.

Q24: Subpart 3.3.1 of Sec on 32 01 18.71 of the specifica on’s states, “Cut grooves in the asphalt areas as indicated on the drawings.” Also, Runway Grooving Note 2 on Sheet C505 of the contract drawings is described as “Grooving Flexible Pavements. “Will the Government please confirm that the Contractor is only required to provide grooving of airfield paving specifically to the overlayed asphalt paving from

Sta on 0+00 through Sta on 57+00, and that grooving of airfield paving is NOT required to be performed on any other exis ng and/or Portland cement concrete (“PCC”) paving along any por on of the exis ng runway?

We are asking this ques on because Subpart 3.1.1 of Sec on 32 01 18.71 of the specifica ons, as well as

Figure 21‐1 on Sheet C505 of the contract drawings, contemplate “Exis ng Pavements” and “PCC

Surface(s).”

A.24 Exis ng Pavements and PCC outside of Sta 0+00 to Sta 57+00 are currently grooved or have stria ons in them. No groove cu ng outside of the new runway pavement area will be required.

Q25: Sec on 32 01 19.61 – Sealing Joints in Rigid Pavement of the specifica ons includes requirements for prepara on of joints and applica on of joint sealants in rigid pavements. The only loca on that the contract drawings indicate that Sec on 32 01 19.61 joint sealants are to be provided is at the interface between the new pavement and exis ng pavement at Full Depth Repair Area No. 1, as indicated by the

Expansion Joint w/ Dowel Detail ‐ Type B3 on Sheet C603 of the contract drawings.

Will the Government please confirm that the Contractor is not required to remove and replace any exis ng joint sealants in exis ng Portland cement concrete (“PCC”) pavements along any por on of the exis ng runway?

We are asking this ques on because Subpart 3.3 of Sec on 32 01 19.61 of the specifica on’s states, “Unless otherwise indicated, remove exis ng material, saw, clean and reseal joints;” however, this specifica on appears to be generic in nature and does not specifically state “where.” While the contract drawings indicate areas along the exis ng runway, specifically PCC pavement areas, where the exis ng pavement markings are to be removed and re‐applied with new, the contract drawings do NOT indicate that any exis ng joint sealants in the exis ng PCC pavements are to be removed and resealed.

A25. ‐‐ No exis ng rigid pavement crack or joint work

Q26: The “Shoulder Crack Quan es” on Sheet C800 of the contract drawings indicates that there will be 8,000 feet of “1/4 Inch Up To 2 Inches” type asphalt crack repairs, which would appear to include the work required by Details 1 and 2 on Sheet C800 of the contract drawings. For the purposes of bidding, will the Government please clarify what quan es, out of the total 8,000 feet, will be applicable to

Detail 1 – Crack Repair Detail ¼” to ¾” Reservoir Fill Method with Flush Finish versus will be applicable to

Detail 2 – Crack Repair Detail ¾” to 2” Flush Finish?

A26 –Please see revised unit price structure as per Addendum 4

Q27: General Note 3 on Sheet C101 of the contract drawings states, “Contractor to no fy base communica ons to mark u li es prior to start of construc on ac vi es. “Will the Government please clarify if the Contractor will be required to pay any costs/fees required for base communica ons to mark u li es?

A27 There is no fee for the base to mark u li es. The Contractor will maintain markings throughout construc on to the best of their ability. A dig permit is required prior to any excava on on base. A Miss Dig number will be provided to the Government by the Contractor to ini ate a Base dig permit. Once the Base permit is completed and signed, the Contractor will be able to commence with excava on. The Government will normally have the permit completed within two weeks.

Q28: The “Millings Disposal Note” on Sheet C101 of the contract drawings states, “Soil from this loca on shall be properly disposed to a licensed landfill if removed from the site . . . OR soil may remain within the area of concern delineated boundaries, covered with topsoil, and site vegeta on restora on (mulch ma ng and seeding) must occur, as soil disturbed areas. See Sheet T100 for milling deposit site loca on.

Contractor is responsible for spreading millings in the approved milling deposit areas.” Will the

Government please clarify if the Contractor is responsible for performing any work in the millings disposal area other than dumping and spreading the millings? For instance, is the Contractor required to cover the spread millings with topsoil, mulch ma ng, and/or seeding as well.

A28 ‐ Stockpile for future use

Q29: Sheet C603 of the contract drawings includes the Runway Shoulder Repair Detail 3. Sheet C603 of the contract drawings is tled “Repair Area 1 Detail.” Is the Runway Shoulder Repair Detail 3 applicable to Full Depth Repair Area Nos. 1, 2, and 3, or only applicable to Full Depth Repair Area No. 1?

A29 ‐ Applies to all full depth areas; Area 1, 2 and 3

Q30. The Contrac on Joint Detail – Type C1 detail 4 on Sheet C603 of the contract drawings states, “Sawcut joint 1/8” wide by 1/4 of slab thickness under AC overlay.” Will the Government please confirm our understanding that joint sealants are not required to be applied to the sawcut joint under the AC overlay?

A30 – Joint sealants ARE required to be applied to the sawcuts, including under the AC overlay.

Q31: Subparts 3.6F and 3.6G of Sec on 01 57 19 of the specifica ons state, “Excess soil can be managed by backfilling na ve material or grading and seeding in the local vicinity or transported to one of the onsite excess soil stockpile areas. Non‐contaminated excess soils may be transported to onsite excess soil stockpile areas . . .” Addi onally, the Special Note on Sheet REF‐01 of the contract drawings states that “soils may be relocated on the installa on.” Will the Government please clarify where the “onsite excess soil stockpile areas” are located?

A31 – The soil spoils from the full depth repair area can remain on Selfridge ANGB at PRL Site 9, see sheet REF-01. There are no requirements for geomembranes. The Contractor will be required to submit an SESC Permit including the proposed soil deposit location, complete with proposed final grades and PE stamp. Stabilization of the spoils is required – i.e., topsoil covering and seeding, with the airfield grass mix being utilized, see Selfridge Design Standards 10 No 2018 Edition “Airfield Grass Seed Mixture: Endophytic Fescue – 100%.” Contractor should be cognizant of total disturbed acreage and limit disturbance to under 5 acres in order to avoid additional regulatory approvals.

Q32: Is the “Buried PCC Slab” indicated on Sheet C601 of the contract drawings limited to the 150‐foot‐ width of the runway, or does the “Buried PCC Slab” con nue a certain distance into each shoulder, like the “CSB” indicated by the Runway Shoulder Repair Detail 3 on Sheet C603 of the contract drawings?

A32 – Buried PCC slab is limited to the 150‐ width of runway

Q33: Page 2 of 4 of the Statement of Work states, “A Macomb County Soil Erosion Permit will be required for this project. The contractor shall obtain, pay for, and follow the requirements of this permit.” Will the Government please clarify if it is aware of any other permits, such as permits from the

State, City, County, or any locality, which the Contractor will have to obtain for this project?

A33 ‐ Any Contractor required permits, i.e., over‐sized loads, mobiliza on permits, etc will be at the Contractor’s expense. Per sheet G101, Note 1, fi h bullet “A FAA 7460‐1" will be required to be submi ed by the Contractor. If soil disturbance, including proposed soil spoil deposit site, is in excess of

5 acres, addi onal EGLE approvals will be required.

Q34: Subpart 2.2B – Temporary Electricity of Sec on 01 51 00 of the specifica on’s states, “The cost of electricity consumed during construc on, up un l beneficial occupancy by SANG shall be paid by the

Government. “However, Subpart 1.32A – Temporary Field Offices of Sec on 01 00 00 of the specifica ons states, “If the contractor has chosen to provide a temporary office at their discre on, all u lity charges will be the responsibility of the Contractor at no addi onal cost to the Government.” Will the Government please confirm that the electricity consumed by the Contractor during construc on will be paid by the Government (per Sec on 01 51 00)?

If not, will the Government please provide the usage rates that will be charged to the Contractor so that the bidders may include these costs in their bid amounts?

A34 ‐‐ $0.118 (very close es mate) per Kilowa Hour will be assessed. Contractor responsible for supplying and installing meter and associated equipment.

Q35: The fourth note on Sheets C401 through C406 of the contract drawings states, “Contractor is required to complete milling and asphalt replacement, temporary Bravo runway markings and return markings to a taxiway, and temporary marking of asphalt surfaces within 6 weeks of mobiliza on to the site.” However, Subpart 1.55 – Construc on Phasing of Sec on 01 00 00 of the specifica ons describes the “Taxiway Bravo Marking Removal,” “Paint Taxiway Bravo Temporary Runway Markings as a VFR

Runway,” “Remove Taxiway Bravo Temporary Runway Markings,” and “Paint Taxiway Bravo” ac vi es as occurring outside of (before and a er) the runway closure period. Will the Government please confirm that the removal of the exis ng pavement markings, pain ng of the temporary runway pavement markings, removal of the temporary runway pavement markings, and pain ng of the taxiway pavement markings along Taxiway Bravo can be performed outside of (before and a er) the runway closure period?

A35 – See Amendment 001 to the solicita on upda ng the Project Drawings

Q36: Subpart 1.55 – Construc on Phasing of Sec on 01 00 00 of the specifica ons includes a task described as “Coordinate Runway Ligh ng and Sign Deac va on.” Will the Government please clarify what specifically will be required of the Contractor to coordinate runway ligh ng and sign deac va on?

A36 Runway Ligh ng and sign deac va on will be coordinated with 127 CES Electrical

Superintendent, Air Traffic Control, and Base Opera ons to insure a safe and smooth transi on to the temporary runway.

Q37: Subpart 2.10C – Temporary Erosion and Sediment Control of Sec on 01 51 00 of the specifica on’s states, “Provide measures to prevent soil erosion and discharge of soil‐bearing water runoff and airborne dust to undisturbed areas and to adjacent proper es and walkways, according to erosion‐ and sedimenta on‐control Drawings CE 100 and requirements of 2003 EPA Construc on General Permit or authori es having jurisdic on, whichever is more stringent.” Sheet CE100 is missing from the contract drawings. Will the Government please provide Sheet CE100 and/or clarify what type of and where temporary erosion and sediment control measures will be required?

A37. The soil spoils from the full depth repair area can remain on Selfridge ANGB at PRL Site 9, see sheet REF‐01. There are no requirements for geomembranes. The Contractor will be required to submit an SESC Permit including the proposed soil deposit loca on, complete with proposed final grades and PE stamp. Stabiliza on of the spoils is required – i.e., topsoil covering and seeding, with the airfield grass mix being u lized, see Selfridge Design Standards 10 No 2018 Edi on “Airfield Grass Seed Mixture:

Endophy c Fescue – 100%.” Contractor should be cognizant of total disturbed acreage and limit disturbance to under 5 acres in order to avoid addi onal regulatory approvals.

Q38: Will the Government please clarify if the sealing of cracks in asphalt paving specified by Sec on 32

01 17.61 of the specifica ons and indicated by Sheet C800 of the contract drawings is required to be performed during the runway closure period (concurrent with the major milling and overlay of the asphalt paving), or if this work can be performed during temporary closure(s) of the runway a er the runway closure period?

A38 All work on the runway will be completed during the runway closure period. Check

Amendment 001 to the Solicita on upda ng the project drawings.

Q39: Are the exis ng u lity services for domes c water, sanitary sewer, and electrical at Selfridge ANG

Base priva zed? If so, will the Government please provide the names and points‐of‐contact to the bidders to coordinate temporary u li es for the Contractor’s temporary trailers during construc on.

A39 There are no u li es available in the designated staging area. There is an area available across from Bldg. 825 (Medical Facility) on Jefferson Rd. to place an office trailer. The Contractor will be responsible to provide the drop, meter and all associated material, equipment, and licensed electrician for the electrical connec on. The Contractor will be billed $0.118 per Kilowa Hour.

Q40: Paragraph 3.1 – Scheduling on Page 86 of 92 of the solicita on states, “If the Contractor desires to work during periods other than above, he must no fy the Contrac ng Officer’s Representa ve (COR) five (5) working days in advance of his inten on to work during other periods to allow assignment of addi onal inspec on forces. When the COR determines that they are reasonably available, he may authorize the Contractor to perform work during periods other than normal duty hours/days. However, if inspectors are required to perform in excess of their normal duty hours/days solely for the benefit of the Contractor, the actual costs of the inspec on, at over me rates, will be charged to the Contractor and will be deducted from the final payment of the Contract amount.”

Addi onally, Paragraph 4.c of the Statement of Work also contemplates working outside of normal working hours. Further, the fi h note on Sheets C401 through C406 of the contract drawings states, “Base will allow flexible work schedule (e.g., 12‐hour workdays, weekend work, etc.) to meet 6‐week construc on schedule.”

Due to the short‐dura on runway closure period and poten al for substan al liquidated damages, it will be necessary to work during periods other than normal working hours in addi on to normal working hours.

Will the Government please confirm that it will approve and authorize the Contractor to perform work during periods other than normal duty hours/days?

Will the Government please clarify what is considered to be “solely for the benefit of the Contractor?”

Would this include any and all work outside of normal working hours?

Will the Government please provide the bidders with the costs(s)/amount(s) (for normal working hours, over me hours, weekend hours, etc.) that the Contractor will be charged for the inspectors performing in excess of their normal working hours/days?

A40 –This language will be deleted from the specifica ons.

Q41: Subpart 1.2C of Sec on 01 00 00 of the specifica on’s states, “Should the Contractor choose to use the South Gate for transpor ng materials in or out of the project site, Contractor will be responsible for coordina ng the security manning of the gate with Base Security. Contractor will also be responsible for reimbursing Base Security or paying the Base Security contractor directly for the addi onal security costs.”

Addi onally, Paragraph 1.xi of the Statement of Work states, “The Contractor will be responsible for coordina ng and funding any addi onal security requirements with Base Security Forces and DK Security to ensure adequate security coverage for the an cipated volume of construc on traffic. In the event the

Southern Construc on gate needs to be opened on a limited basis, the Contractor will be responsible for coordina ng and funding the required security personnel.”

Sheet C100 of the contract drawings appears to designate the South Gate as the “Construc on Entry

Point.”

Will the Government please clarify what alterna ve(s) the Contractor may choose to use for transpor ng materials in or out of the project site (other than the South Gate)?”

A41 – Use of the South Gate for access to the airfield is a requirement. If addi onal security is not able to be procured to man the south perimeter construc on gate (off N. River Rd) then the

Contractor will have to use the main gate for accessing the base

Will the Government please clarify what specifically is required by the requirements – “coordina ng the security manning of the gate with Base Security” and “coordina ng and funding any addi onal security requirements?” For instance, is this simply making payment for security manning of the gate, or will there also be addi onal work and/or provisions involved with manning of the gate for which the

Contractor will be responsible?

A – Funding the addi onal manning requirements u lizing the exis ng DK Security Contract

Will the Government please provide the bidders with the costs(s)/amount(s) (for normal working hours, over me hours, weekend hours, etc.) that the Contractor will be responsible for reimbursing Base

Security and/or paying the Base Security contractor (DK Security) directly for the addi onal security costs?

A ‐ per DAFI 31‐101, para. 3.6.7., commercial vehicle inspec on (CVI) areas (commercial trucks) must be manned with two armed individuals at all mes while the in opera on.

Aggregate hourly cost for armed individual: $60/hour

Government vehicle not provided. Contractor required to provide vehicle for armed individual.

Will the Government please provide the bidders with the point‐of‐contact and contact informa on for the Base Security contractor (DK Security)?

A ‐ Mr. Ermswiler @ jakobemswiler@dksecurity.com from DK Security

Q42 Please clarify if the concrete reinforcing bars are epoxy‐coated, dual‐coated, stainless steel, or uncoated. Specifica on Sec on 03 30 00, Subparts 2.6.1.1, 2.6.1.2, and 2.6.1.3 list three different materials for the reinforcing bars and it is not clear what is to be provided.

The drawing details on Sheet C601 state only deformed bars.

A42 Epoxy‐coated

Q43: Subpart 1.5 Contractor Quality Control Staff of Sec on 32 12 15.13 of the specifica ons includes a

Footnote (1) for the Airfield Asphalt Pavement QC Manager, Airfield Asphalt Pavement Inspector, and

Airfield Asphalt Pavement Technician, which states, “Registra on for the Airfield Asphalt Pavement

Cer fica on Program can be found at www.airfieldasphaltcert.com.”

Is it the Government’s intent that these three posi ons are required to obtain these cer fica ons?

A43a. Yes

Addi onally, is the “U.S. Army Corps of Engineers Transporta on Systems Center two‐day combined

Airfield PCC and HMA Paving Workshop” described in Item 1.a.i of the Statement of Work document the same program, or in addi on to the Airfield Asphalt Pavement Cer fica on Program?

A43b. The same program

Q44: Subpart 1.28 – Site Cleanup of Sec on 01 00 00 of the specifica ons states, “All roadways, taxiways, and ramp areas within the work area, or used by the Contractor, shall be swept and vacuumed daily to assure safe opera ons of aircra .”

Will the Government clarify if the Contractor is required to maintain a vacuum sweep truck on‐site at all mes during the performance of the work within the work area?

A44: VGLZ 172042 Drawings, Pg. G101, FOREIGN OBJECT DEBRIS (FOD) MANAGEMENT, A MINIMUM OF ONE SWEEPER SHALL BE ON‐SITE AND OPERATIONAL AT ALL TIMES. THIS

SWEEPER SHALL BE DEDICATED FOR THE EXCLUSIVE USE OF CLEANING AND FOD FROM THE RUNWAY, TAXIWAY, AND TAXILANE AREAS. THE BROOM SHALL NOT BE COMPRISED BRISTLES.

Q45 The copy of the slideshow issued a er the pre‐bid site visits states, “Project requirements include

Mill and overlay approximately 6.5 inch of asphalt . . .”

The contract drawings indicate that 6.25 inches of asphalt is to be milled and overlayed.

The contract drawings indicate that 6.25 inches of asphalt is to be milled and overlayed. Will the

Government please confirm that 6.25 inches, not 6.5 inches, is the correct thickness?

A45 – No less than 6.25”, compacted thickness, of asphalt shall be placed. Maintain REQUIRED final grade as shown on the profile drawings. Sheet C101 provides the Control Points. The contractor shall maintain the proposed grade on the contract documents, have a minimum 1” of exis ng asphalt pavement le in place, with a minimum of 6.25” overlay of asphalt. Historic data, borings, logs and drawings indicated differing thicknesses on the runway ranging from 6” to 9.5” thick. Contractor should assume 20% of the runway would need addi onal asphalt because the exis ng asphalt thickness is between 7.25” and 6.25” thick. The slideshow descrip on is not a contractual item.

Q46: Due to the short dura on provided for the runway closure and the risk of substan al liquidated damages for this contract, will the Government be willing to provide expedited reviews of submi als, test sec on results, and other test/inspec on reports during the performance of the work? This will be necessary in order to allow ample me to complete the physical work during the runway closure period.

As one example, Subparts 3.6 through 3.6.2 of Sec on 32 12 15.13 of the specifica ons provides the requirements for the test sec on for the airfield asphalt paving, which is required to be performed prior to full produc on paving. Subpart 3.6.1 states, “Construc on may con nue provided the test results are within the tolerances or exceed the minimum values shown in Table 11;” however, Subpart 3.6.2 states, “Full produc on paving is not allowed to begin un l an acceptable test sec on has been constructed and accepted.”

As a second example, Subpart 3.6.2 of Sec on 32 11 23.23 of the specifica ons states, “Construct the test sec on a minimum of 30 days prior to the start of full‐scale produc on to provide sufficient me for an evalua on of the proposed materials, equipment and procedures including Government QA tes ng.”

A46 – Expedited reviews of submi als, test sec on results and other reports during the performance of the work will be supported to the greatest extent prac cable

Q47 Please find below a few ques ons pertaining to the requirement for the bidders to submit bids by way of CDs, as specified by Subpart 2.4 of Sec on 00 21 00 – Instruc ons of the solicita on?

1) Subpart 4(e) of Sec on 00 10 00 of the solicita on states, “When comple ng the ‘Offeror’ por on of the SF 1442 (Blocks 14 – 20), an official having the authority to contractually bind the company must sign the SF 1442 in accordance with FAR 4.102. One copy of the SF 1442 is required to have an original signature.” However, the solicita on requires bidders to submit bids by way of CDs; therefore, there will only be a scanned copy of the original signature. Will the Government please confirm our understanding that the bidders will only be required to provide a scanned copy of the signed bid, not an original?

2) Box 13, Item A on the Standard Form 1442 states, “Sealed offers in original and 1 copy to perform the work are due . . .” Will the Government please clarify if the bidders are required to submit only one (1) CD (an “original”), or two (2) CDs (one as an “original” and one as a “copy”)?

3) Since hand‐carried bids are required for this solicita on, this will require the individuals delivering the bids to enter the bid amounts electronically and then burn CDs at the bid repository loca on just prior to the bid deadline. Would the Government please reconsider requiring the bid documents be submi ed by way of CDs and, instead, allow the bid documents to be submi ed in the more‐common fashion of physical paper‐copies to avoid the last‐minute task of burning CDs?

4) Alterna vely, would the Government please reconsider requiring the bid documents to be hand‐carried bids and instead consider allowing the bid documents to be submi ed electronically through email? This would maintain the Government’s desire to receive electronic versions of the bids.

A47. A CD is desired as supplemental to the 2 paper copies (1 original and 1 copy) required by the invita on for bids. Bids may be mailed to the contrac ng office in, or hand delivered. No email, facsimile or other electronically transmi ed bids will be accepted. The bidder is responsible for mely submission of bids regardless of if the bids are hand delivered or mailed.

Q48: Will the Government please consider extending the bid due date by two addi onal weeks?

This will allow me for the bidders and the subcontractors to receive, review, and understand the forthcoming clarifica ons to the pre‐bid inquiries, and allow adequate me to plan and coordinate the work, schedule, and security‐related requirements for the project that are necessary to finalize the bids.

We request a two‐week extension, as a one‐week extension would place the bid due date between the

Christmas and New Year’s Day holidays, when many contractors are not working, which would decrease the amount of par cipa on and compe veness of the bids.

We believe that having the Government’s clarifica ons to the pre‐bid inquires and extending the bid due date to the end of the first week of the year will increase par cipa on and the compe veness of the bids.

A48 – Please see Amendment 2 issued on 20 December 23.

Q49. Will the Prime contractor be required to have an onsite asphalt material tes ng lab or will a USACE

MTC validated lab that is offsite be sufficient to meet the QC Requirements set forth in the specifica ons?

A49. ‐ Sec on 32 12 15.13 requires the batch plant to have a fully equipped asphalt laboratory.

An off‐site MTC Validated lab is sufficient. The Contractor MAY establish an on‐site lab, but the Contractor will be required, at no cost to the Government, to validate any on‐site lab with the USACE MTC at the links provided in sec ons 01 45 00.00, part 3.7.2 and 32 12 15.13, part1.6.11.

Any delays caused by the Contractor due to their op ng to NOT u lize an on‐site lab will be the responsibility of the Contractor and shall not result in any addi onal costs to the Government.

Q50. For the cement stabiliza on, the specs read that the cement stabilized material is to be placed by a paver. However, given that the cement stabilized material is only for the repair areas, it doesn’t seem to make sense to try and put a paver in the hole and a empt to pave it. Will a paver be required for this work, or will an alternate method be acceptable?

A50 – A paver will be required for the Cement Stabilized Base per specifica on 32 11 23.23.

Q51: Will alternate technology be allowed to measure the ride quality of finished surfaces? Currently the specifica ons require the California Profilograph, but newer technology is available to measure ride quality.

A51 – For bidding purposes, assume the California Profilograph will be the requirement. Alternate technologies presented will be evaluated on a case‐by‐case basis and in coordina on with CETSC or AFCEC

Q52: Will the excavated materials and broken concrete from the repair areas remain onsite or will these materials need to be hauled offsite?

A52 – Remain on‐site at the proposed milling deposit loca ons.

Q53: Does the Grooving stop 10’ from where the new pavement meets the exis ng shoulder?

A53 – Grooving terminates 10’ from the runway edges; excludes shoulders.

Q54: Taxiway Bravo is for daylight use only so no temporary ligh ng is required, only pavement markings?

A54 Correct

Q55. as the contractor required to spread the millings or stockpile? What is the pile height of the milling stockpile?

Our past experience is when asphalt milling are stockpiled, There is possibility it may be difficult to spread at a later date.

A55 – Millings are to be stockpiled at Area 5 (see pg. C100 )

‐ Pg. C101, General notes, 1., CONTRACTOR IS RESPONSIBLE FOR LABOR AND

EQUIPMENT TO SPREAD MILLINGS. MILLINGS

STAGING PILE CANNOT EXCEED THE HEIGHT OF ADJACENT TREETOPS

Q56. Sheet C301 states If less than 1” of asphalt remains a er 6.25” of milling contractor needs to mill full depth. How does contractor get paid for addi onal asphalt pavement installed under a lump sum bid?

A56 –Please see unit priced line item structure in Amendment 4

Q57: Sheet C301 states If less than 1” of asphalt remains a er 6.25” of milling contractor needs to mill full depth. How does contractor get paid for addi onal asphalt pavement installed under a lump sum bid?

A57 – Please see unit price line item structure in Amendment 4 .

Q58. Leaving 1” of asphalt pavement per the detail on sheet C301 may not hold up construc on traffic to repair the runway. If pavement breaks up how will we handle paving over deteriorated pavement? Lump

Sum Contract?

A58 – Please see unit priced line item structure in Addendum 4

Q59: specifica on are unclear on what is happening with the excava on from the repair areas. Sec on

02 61 13 1.1.2.1 men ons on site transporta on of contaminated material. 1.3 Descrip on of Work states contaminated material and ground water are not expected.

Is the inten on for the excavated material to be hauled to an on‐site stockpile as has been fairly common with past projects on the site? And would this apply to clean and contaminated materials and approximately where on site would this be so we can figure trucking properly.

If the material is to be handled as contaminated there is a total of 13 pages of the spec sec on on how it is to be handled. Even if it is to remain on site there is significant costs associated with stockpiling and the geomembranes needed. If offsite disposal is required for Contaminated Non‐Hazardous material or

Hazardous Material is involved the cost are more significant.

As this is a lump sum bid clarifica on on how the excava on will be handled could significantly impact pricing based on the requirement. If the material is expected to be clean, we would just need a note for on site or offsite hauling. Then I would suggest a unit price for Contaminated material to a standard Class

II Unit price to keep everyone on the same playing field.

A59 – The soil spoils from the full depth repair area can remain on Selfridge ANGB at PRL Site 9, see sheet REF‐01. There are no requirements for geomembranes. The Contractor will be required to submit an SESC Permit including the proposed soil deposit loca on, complete with proposed final grades and PE stamp. Stabiliza on of the spoils is required – i.e. topsoil covering and seeding, with the airfield grass mix being u lized, see Selfridge Design Standards 10 No 2018 Edi on “Airfield Grass Seed Mixture:

Endophy c Fescue – 100%.” Contractor should be cognizant of total disturbed acreage and limit disturbance to under 5 acres in order to avoid addi onal regulatory approvals.

Q60. What is the status of the many RFIs submi ed for this project? Bid is due Friday and many of the ques ons have not received answers.

A. 60. They are being answered as quickly as prac cable. We will extend the bid due date as applicable.

Q61: Does the 30 Day wai ng period a er final paving and before the grooving/final pavement markings count against the Calendar Days of the contract

A61: Yes. All work on contract to include closeout documents and site restora on count against the Calander days of the contract.

Q.62 Does the nightwork in Phase 1A, Phase 2A, Phase 2C, and Phase 3A count towards the Calendar days of the project?

A62: Calendar days are independent of shi s worked.

Q63 How many calendar days is this project? Within the general descrip on, the project states the contractor has 84 Calendar Days to open a fully func onal runway. However, the phasing plan provided in Addendum 1 indicates 88 Calendar days. This 88 Calendar Days does not include any nightwork or the

30 Day wai ng period between final paving and grooving. The phasing plan breakdown is as follows:

Phase 1 and Phase 1A: 14 Calendar Days (Phase 1A happens at night and concurrently with Phase 1)

Phase 2, 2A, 2B: 60 Calendar Days (2A Work is at Nights and concurrent with 2 and 2B)

Wait 30 Days before grooving and final pavement markings

Phase 2C: 21 Nights

Phase 3 and 3A: 14 Days (3A occurs at night and is concurrent with Phase 3)

A63 – See SOW for the POP requirements for runway closure and the en re project. Any melines presented in the CSPP (Sheets G101 through G503) are for demonstra ons purposes.

Q64: What work must be completed for the airport to be considered a “fully func onal” runway?

A64: All work on contract, aside from restora on

Q65 Is the nightwork for Phase 2C to be included in the 60 Days for Phase 2, Phase 2B, and 2A. Will Phase

2C nights be counted as calendar days against the project?

A65 – Calendar days are independent of shi s worked. The nightwork days displayed on the G‐ series sheets are for general guidance and display purposes only. The Contractor may work more, or less, night shi s required to meet the 84 Calendar day POP for the runway closure.

Q66 Is the owner having a tes ng company do QA Tes ng? Has a tes ng company already been selected?

There are only a handful of tes ng companies cer fied to do airport tes ng and we need a third party

Company to verify our QC tes ng results.\

A66 – The Government has not selected a Type C Services Contractor at this me. This will be a requirement on their contract and will be coordinated with the Contractor selected for this Contrac ng

Ac on.

Q67: How are we going to handle Pay Factors for HMA tes ng if this is a lump sum project?

A67 – This will be treated as a credit via contract modifica on. The contractual basis for this work/price element is paragraph f of the Inspec on of Construc on clause at 52.246‐12

Q68. With several ques ons s ll not answered, will the Bid Date be extended?

A68 –Please see amendment 2 issued on 20 December

Q69:. If the Runway 01‐19 is closed un l grooving and final pavement marking as per the contract. In

Addendum #1 plans There is a note sta ng Phase 2C Runway and Taxiway Pavement Grooving and

Pavement Markings on Runway 01‐19 And Taxiway has to be completed at night from 10 PM to 6 AM. Do we have to do this work at night?

A69 – Night work is an cipated due to the accelerated schedule. Night shi s provided on the phasing plan are for general guidance and display purposes only. Night shi s are not a requirement

Q70: Since these repairs are small in dimensions can the Cement Stabiliza on process be performed in place in lieu of the pug mill process as stated in the proposal. I’ve be informed the in place process for cement stabiliza on was completed recently on the Airport Grounds using this cement stabiliza on process for patches?

A70 – No. See specifica on 32 11 23.23, sec on 1.4.4. The specifica on does not allow for alterna ve mixing processes. The OGM Stabilized course has a Job Mix Formula (JMF) submi al requirement as well. Specifica on 32 11 23.23, sec on 1.4.2 provides that if the Contractor can establish that an alternate PLACEMENT method (other than using an asphalt paver as specified) produces results that meet the required specifica ons, that would be submi ed on the test sec on report for the required test sec on a er project award and kick‐off. Any delays or costs associated with a rejected alternate placement method proposal will be the responsibility of the Contractor.

Q71: We are reques ng further clarifica on regarding the contractual period of performance (i.e., overall dura on) and the construc on phasing and sequencing requirements, especially as it relates to the runway closure period. Please find below ques ons reques ng clarifica on regarding conflic ng informa on that has been provided.

The Government provided an en rely new set of contract drawings with Amendment No. 0001.

The new set of contract drawings included “Construc on Phasing Notes” on Sheet G101 and prescrip ve

“Phasing General Notes,” “Dura on(s),” and “Construc on Ac vi es” related to the phases (and sub‐ phases) on Sheets G201, G202, and G203 of the contract drawings. Addi onally, Sheets C401 through

C406 of the contract drawings were revised to include note(s) sta ng, “Contractor is required to complete milling and asphalt replacement, temporary Bravo runway markings and return markings to a taxiway, and temporary marking of asphalt surfaces within the dura on specified on CSPP Sheets G201 to G203.”

The revisions provided with Amendment No. 0001 were generally in conformance with the requirements contained within Subpart 1.55 “Construc on Phasing” and Subpart 1.60 “Work Schedule” of Sec on 01

00 00 of the specifica ons—Phase(s) 1 and 1A include the “Pre‐Runway Closure Tasks,” Phase(s) 2, 2B, and 2A include the “Runway Closure Tasks,” and Phase(s) 3, 3A, and 2C include the “Post Runway Closure

Tasks.” The contract drawings and specifica ons clearly provide for certain work ac vi es to be performed prior to the runway closure period, certain work ac vi es to be performed during the runway closure period, and certain work ac vi es to be performed a er the runway closure period.

However, the Government’s answers to certain requests for informa on (“RFIs”) posted to

SAM.gov on 26 December 2023 contradict the informa on contained within the contract drawings and specifica ons. A bidder posted a few ques ons regarding the dura on and construc on phasing requirements provided with Amendment No. 0001 in Ques ons Q63, Q64, Q65, Q69, to which the

Government responded as follows:

“A63 – See SOW for the POP requirements for runway closure and the en re project.
