Question Answer Please confirm we are to dismantle the two existing rows of 4 bay parking spots. We are submitting this question as during the site walk there was some discussion of dismantling one row of 5 bay parking. Confirmed that only the two existing rows of 4 bay parking sports are being dismantled.

Does the government intend to publish the original sunshade drawings that were submitted stamped, sealed, and with the words “Confidential Property of Agate, Inc” along with patent-pending? Did the government receive in writing from Agate, Inc. permission to publish the company’s proprietary information?

There is no current patent on the original sunshade drawings. IAW FAR 52.236‐21 (d) Shop drawings means drawings, submitted to the Government by the Contractor, subcontractor, or any lower tier subcontractor pursuant to a construction contract, showing in detail (1) the proposed fabrication and assembly of structural elements, and (2) the installation (i.e., fit, and attachment details) of materials or equipment. It includes drawings, diagrams, layouts, schematics, descriptive literature, illustrations, schedules, performance and test data, and similar materials furnished by the contractor to explain in detail specific portions of the work required by the contract. The Government may duplicate, use, and disclose in any manner and for any purpose shop drawings delivered under this contract.

The existing sunshades were constructed in 2005. The existing sunshades were engineered per 1997 UBC, 12 PSF roof live load, 80 mph wind load, exposure “C”, 4 PSF framing load, and designed in accordance with seismic zone 2B (Ca-0.28). The specification states “Provide certified engineered drawings for the re-construction of the eight sunshades. In addition, the specifications reference the Contractor shall be responsible for researching all historical weather conditions within the local area and shall install the sunshades to withstand these conditions. Wind pressure shall be computed and applied using a basic wind speed of 110 miles per hour. If certain members do not meet the government's desired 2018 International Building Code should the Contractor include the cost of a new steel member in the base bid? Yes, if there are new members to be added, the Contractor should include that cost in the base bid.

Under the description of work – “Conduits shall be removed vertically to the 90-degree bend avoiding water getting into the conduit.”. Please describe what we are to do with the existing end of the conduit? Are we to plug the end of the conduit and simply patch the concrete? Yes. Plug the conduit and then patch the concrete.

The scope of work states, “Full depth replacement of concrete where existing anchor bolts flush existed and fill voids with a pourable epoxy.” The existing anchor bolts are 4 each per column - ¾” diameter embedded deep into the concrete. In past projects we simply grind the anchor bolts down below the flightline concrete surface and cap them with a pourable epoxy. Please clarify how the contractor is to remove and cap the existing anchor bolts?

The existing bolts at Kirtland will need to be completed removed and the concrete will need to be filled where the bolts were displaced. They will not be ground down.

Under specification L-10. Submitting The Proposal - Please confirm we can submit the 20% Bid Bond with the Bid Proposal via email? No. Please submit all bonding as hard copies with the original raised seal.

Please confirm that all existing bolts and fasteners are to be replaced with new ones that are made in American?

Does the government require the existing cable bracing, strand grips, eye bolts, hillside washers, and nuts to be replaced? If they are not in good working condition, or do not function properly, yes.

It was pointed out on the end of the canopy a series of screws, closely spaced, 6” o.c. that were used to retain the end screen fabricate. Will the government require all of the existing fasteners be removed and discarded before new sunscreen is applied?

Yes, they will need to be removed in order to place a new fabric canopy. After installation, fasteners will need to be replaced as required.

Along the lines of question #10, will all of the screws remaining in the tops of each purlin be required to be removed before the new sunscreen fabricate is applied? If they are in the way of installing the new fabric, they will need to be removed and replaced after installation.

Does the government want the sunshade steel repainted before the new sunscreen is applied? We are submitting this question because the scope of work refers us to the Installation Excellence Guide Air Education and Training Command. Within the specification of the AETC, it references the local command colors to be selected within the range of neutral and earth tones If the sunshade needs to be reapinted, the Contractor will do so before the canopy is installed.

The scope of work does not address if the government wants new sunscreen applied to the ends of the parking rows. Please clarify? Yes, sunscreen will be applied to the ends of the rowsd as well as the tops.

Will the government require a manufacturer’s warranty on the re-constructed sunshades? If yes, how many years?

Warranty will be whatever the current commercial standard is at no additional cost or for one year upon project final acceptance.

The Contractor is to “Provide certified engineered concrete foundation drawings based on the existing expansion soils. New sunshades foundations will include 30-inch diameter x 13-feet-0-inches deep, drilled concrete caissons with engineered steel reinforcements.” The specifications reference UFC 3-220-01 Geotechnical Engineering, will the government provide a geotechnical soils investigation for the new location at Laughlin? If not, will the Contractor be required to perform a geotechnical soil investigation? No, Laughlin is not capable of doing this testing. The contractor will have to do the investigation.

How thick is the existing flightline concrete at Laughlin AFB where we are to install the sunshades?

SOW states the Contractor shall conduct site surveys to include above and below ground grade conditions assessments. The Government does not have that information on file.

Concrete sampling and testing, will the government provide this service, or will the Contractor pay for the services of a third-party testing company? The contractor will be required to look into third‐party testing.

Will the government provide the following information for Laughlin AFB. Currently there are no existing as‐builts on file.

Netting holes will be no larger than 3/4".

Under the structural design criteria, the government provided the aircraft dimensions and clearances for the desired parked plane. Has the government checked and confirmed the specified aircraft will properly fit under the sunshades with the required clearances? If the specified aircraft encroaches within a clearance dimension is the government willing to issue a waiver? Yes, the aircraft fit under the sunshades.

The specification references UFC 3-575-01 Lightning and Static Electricity Protection Systems. Within this broad specification are NFPA 70 and NFPA 780. Yes Shepherd’s Crook – without existing drawings please specify how many new static grounding units the Contractor is required to install?

Needs to be new material. Number of rods depends on how many aircraft go in each bay and how many tie downs are required per aircraft. Should be 48 total

Under lightning protection and grounding – please clarify if the relocated sunshades are to be grounded? Sunshades shall be grounded per UFC and NEC.

Does the government desire air terminals to be installed to enhance the overall lightning protection to the sunshade?

Follow NFPA 780 and UFC 3‐757‐01. From UFC: If lightning protection is required and the structure is steel I‐ beam or roundheavy beam construction and continuous to ground, air terminals are not necessary as thestructural steel forms a large air terminal. Grounding will be addressed specific to each facility.Tubular steel assemblies do not meet the intent of protection against lightning

What is the desired light intensity of the LED fixtures to illuminate the aircraft under the sunshades? Lighting intensity needs to be in conformance with UFC 5‐530‐01 Before commencing onsite work at the Laughlin AFB site, we understand the requirements for filling out the AF Form 103 and the AF 3000 Form.

Yes, the Government will require the Contrator to use GPR to scan the airfield for concrete caissons.

Under the barricade specification, it states, “Contractor shall use Low Profile Construction Barricades.

Barricades shall have no separation or as instructed by the CO.” Please clarify if we can space the barricades apart if they are tied together with colored rope and if so at what is the maximum spacing permitted? Barricades must connect together. Spacing with rope does not prevent FOD When working on the flight line will portable toilets be permitted, or will the Contractor be directed to use the permanent restrooms on-site? Portable toilets are not to be on the airfield due to winds

Within the specification titled, “On-Site Field Oversight” – A superintendent and Quality Control (QC) manager, approved by the Government, must be on-site whenever work is being performed. The superintendent and the QC manager shall not be the same person.” There was a verbal discussion regarding this requirement, and we would like to obtain further clarification.

For this project, the superintendent and Quality Control manager will be required to be two separate individuals.

If we submit the resume of our superintendent and can establish 10+ years of experience working on active flight lines will the government allow our superintendent to also be our Quality Control Manager? No.

Under Existing Site Conditions, it states the Contractor is responsible to conduct a site survey and validate existing site conditions. It goes on to state “Above and below grade condition assessment”. Please confirm the government will provide a soil report and as-built of the proposed area for construction or the requirement for below-grade condition assessment will not be obtainable. The Government does not have any existing soil reports or as‐builts for this area.

Under specification section 5.4 Warranty – The Contractor shall prepare and submit the Transfer and Acceptance of DoD Real Property. If the sunshades are going to be considered real property, then please clarify if this project is subject to Prevailing Wages? If yes, please provide a copy of the Prevailing Wage Determination. Additionally, under the Laughlin specifications, 12.4 Temporary Signage, it references the displaying of the Wage Decision. Lastly, there is a reference under contract clauses 52.222-6 Construction Wage Rate Requirements. The Government has posted the prevailing wage determinations with this amendment.

Under specification section 5.4 Warranty – “The bolting to the concrete shall have a 5-year warranty against any material defects, corrosion, and deterioration.” During our site visit at Kirtland AFB, it was mentioned the existing sunshades were constructed in 2005. The 17-year-old paint has held up well but has some signs of corrosion developing around the base plates and connections. Please clarify if the government wants the sunshades repainted or waive the 5-year warranty against corrosion and deterioration? The government would like the sunshades repainted to match the existing sunshades.

This depth varies between 12" and 24" Will the contractor have access to the entire area where the 2 new canopies are being installed for the duration of the project? Yes The SOW calls minimum clearance requirements the Aircraft . These are structures have been previously been fabricated to their current dimensions. Has this been taken into consideration? Yes.

Will trucks carrying the canopies be allowed access during normal business HRS ? Yes Will major lifting activities be allowed during normal business HRS ? Yes The finishes on the existing structure has held out fairly well , will Laughlin accept paint touchups or will we be required to paint the entire structure to meet Laughlin paint scheme? If it does not meet Laughlin requirmentrs, the whole structures will need to be repainted to standards.

Will the superintendent / quality control be allowed to be the same person? No.

Can you please provide the wage scales for both locations? Wage scales have been published as part of this amendment.

Please provide as-built drawings for flight line Rows X and Y reflecting the following information:

Currently there are only partial as‐builts for the CASS system. Please see the attached information to the solicitation.

Current dimensional airfield paint markings. Will the existing striping be sufficient? If not please provide the new proposed layout? Can you provide a specification for the aircraft pavement markings? Striping will be required at Laughlin AFB. Specification for striping are in UFC 3‐260‐01.

What is the quantity of existing aircraft tie downs? If current tie-downs are in the wrong locations please provide the quantity to be removed and a drawing reflecting the desired new locations.

In accordance with the SOW the Contractor shall conduct a site survey to ID, verify, and validate exisitng site conditions.

There was a verbal comment made onsite about relocating the air and power underground. Please provide as-builts of the current utility locations and a drawing reflecting the new desired locations. Currently there are no existing as‐builts on file.

Please provide the current thickness of the existing flight line concrete? The Government does not have any existing soil reports or as‐builts for this area.

Can the government provide a soil report for two new rows of concrete caissons? If a geotechnical report is not available will the government require the Contractor to provide one to support the new concrete foundations? If the Contractor has to perform a geotechnical investigation, may we perform these tasks during the workweek or must we perform the work on the weekend? The Government does not have any existing soil reports or as‐builts for this area.

Does the government want the Contractor to install the concrete caissons as drawn or does the government require the Contractor to provide new engineered concrete caissons per either an existing soils report or a new one that the Contractor is required to develop? Since we do not have as‐builts, the Contractor will need to provide new engineered caissons.

Are there any written specifications and or requirements for installing the new concrete foundation into the existing flight line concrete? Are we required to simply patch back in the immediate area of the new concrete foundation or remove and replace the existing concrete with the next existing concrete to the nearest existing concrete joint?

There are currently no written specification for installing new concrete foundation. Please ensure all work meets criteria set forth in the UFCs.

Can the government provide information on the desired LED lights and obstruction lights? It was mentioned at the site walk that the government could provide the make and model of the desired electrical fixtures.

Lighting intensity needs to be in conformance with UFC 5‐530‐01. A specific light will not be directed by the Government. Any light fixtures will be submitted as a submittal for approval.

Will the Contractor be permitted to work both Row X and Y simultaneously? If yes there is considerable savings in both time and money associated with the efficiency. Yes.

We understand we must install FAA low profile, lighted barricades around the perimeter of our work area.

May we stretch them 10’ apart and tie them together with colored rope or do you require the barricades to be interlocked? Barricades must connect together. Spacing with rope does not prevent FOD After the construction of the sunshades, and FOD inspection, does the base require the Contractor to run a vacuum truck over the entire work area before the base will accept the sunshades?

FOD must be removed at all times. Vacuum is preferred however other means are acceptable as long as all FOD is removed.

Will the bid submittal form be modified to separate the costs associated with Kirtland AFB vs. Laughlin AFB? This question was raised due to the New Mexico tax situation.

An additional line item has been added in order to separate the costs associated with Kirtland AFB and Laughlin

AFB.

We understand the current project is not funded but maybe by September 30th. Based on today’s turbulent times with material shortages and constant material increases we will have to bid to extend the pricing for an extended time. Can the government state how long the bid proposal is to remain valid? The longer we have to hold the price the larger the material escalation contingency will be added.

Proposals must remain valid for 90 days after the proposal closing date in accorandance with the solicitation, block 13.d.

The current specifications reflect 75 Calendar days for the engineering and permits and 150 Calendar days for construction. When you evaluate Calendar days vs. workdays less the required time for review and approval the current times are tight and may not be achievable. Can the government extend the times to 90 workdays and 160 workdays?

In accordance with the solicitation, block 11 the period of performance is negotiable. Please include proposed period of performance in the submitted proposal.

Based on the number of questions to be responded to, the upcoming holiday, we are requesting a time extension to submit the bid 3 weeks after the receipt of the final government responses.

This proposal was extended in order to ensure all questions are answered. This amendment is allowing for a second round of questions and the government will continue to review all information to allow for adequate time for proposal preparation and submission.

Can you please provide copies of the site visit sign in sheets? No. Sign in sheets will not be made publically available.

Statement of Work Section 2. Description of Work states to provide Obstruction Lighting for Sunshades.

During the site visit it was indicated that a Make and Model for the desired lights could be provided. Please provide. Please reference question 59.

Statement of Work Section 2. Description of Work states to provide Obstruction Lighting for Sunshades.

What quantity of lights is required per bay? Should it match the existing quantity installed on the shade structures? Reference UFC 3‐535‐01, Chapter 06 During the site visit at Laughlin electrical was discussed. Please confirm that the only electrical required is for the obstruction lighting. If not, what other electrical requirements are included in the project? Electrical will also be required for the GPUs During the site visit at Laughlin the government discussed an electrical panel in Building 219 that would feed the project. There was an electrical manhole located near the future sunshade’s location. Is there a spare conduit running from this manhole to the electrical panel that can be used for obstruction lighting power or will trenching all the way back to the electrical building be required? If trenching is required this will result in signifcant additional cost to the project.

Since the government does not have the as‐builts, this is something that will have to have eyes‐on. A small amount of trecnhing may be required.

During the site visit at Laughlin the government discussed an electrical panel in Building 219 that would feed the project. This building was not visited during the site walk. Please provide a map showing the location of this building. This map is not currently approved for release.

During the site visit at Laughlin the government discussed an electrical panel in Building 219 that would feed the project. This building was not visited during the site walk. If a spare conduit is not available, then trenching to this panel will be required. Is the panel located inside the building or outside? This is not an actual building but rather a fenced in area. That is where the panel will be located.

During the site visit at Laughlin the government discussed an electrical panel in Building 219 that would feed the project. This building was not visited during the site walk. Has the government confirmed that this panel has available capacity to accommodate the new lighting load? The government will need to get eyes on the panel to verify that it is large enough/has the capacity.

Will a disconnect or subpanel for the obstruction lighting be required at each sunshade? An electrical panel or disconnect will be needed for any lighting or outlets at each sunshade There is no mention in the SOW for an engineer signed and sealed electrical design. Is an engineer signed and sealed electrical design required as part of this project for the obstruction lighting and associated electrical feeds? Should not need a design. There are specs and requirements in the UFCs and NECs SOW Section 3.5 states that the structure shall be properly grounded to provide protection against any electrical surges, to include, but not limited to, lightning protection and surges from primary feeder. Please confirm that each shade structure is required to have a lightning protection system engineered and installed? Yes, this is requried.

SOW Section 3.5 states that the structure shall be properly grounded to provide protection against any electrical surges, to include, but not limited to, lightning protection and surges from primary feeder. Do we have to provide surge protection at the electrical panel feeding the obstruction lighting or is surge protection already in place at that panel? Panel has surge protection

SOW Section 3.5 states, “the sunshades' electrical power system shall be installed to have power brought to them from Laughlin AFB's primary electrical power distribution. Coordination with Rio Grande Electric Coop (RGEC) shall be made for any primary electrical requirements and installation. The Government shall assist the Contractor in this.” This conflicts to what was discussed at the site visit. Is the panel that was discussed in Building 219 owned by RGEC or the government? Government owns panel. No coordination with RGEC is needed.

SOW Paragraph 5.2 states, “Commissioning shall be done for electrical (grounding, lighting). Is this commissioning required to be performed by a 3rd party commissioning agent? Commissiong shall be in accordance with UFCs and standard practices.

At the Laughlin site visit we observed that a new trench was installed the length of where the canopy will be installed that appears to provide utilities to a Compressed Air system. Please provide As-Built drawings that indicate what is located in these trenches showing depth of utilities, type of utilities, etc.

Currently there are only partial as‐builts for the CASS system. Please see the attached information to the solicitation.

Please provide any specific underground utility trench requirements (minimum depth to electrical conduits, bedding requirements). Please see the trenching attachment.

Please provide pavement section requirements for patching of any underground utility trench to include base type and thickness, concrete type and thickness, and any reinforcement requirements. Please see the trenching attachment.

Is all concrete on the airfield required to meet 650 psi flexural strength or will the government accept compressive strength test data? Please note there is no current test data for 650 flexural strength concrete in the Laughlin or San Antonio areas. If required to submit 650 psi flex test data then contract will incur significant cost and schedule impacts to prepare an acceptable mix design. Please provide the data for review.

Please confirm that 650 psi flexural strength concrete will not be required for sunshade column foundations as these will not be subject to airfield wheel loading? Please provide the test data.

During the Laughlin site visit the government had a drawing showing the approximate placement of the sunshades. Can the government provide this exhibit? Currently there are no existing as‐built on file.

Statement of Work Section 2. Description of Work states full depth replacement of concrete where existing anchors bolts flush existed and fill voids with a pourable epoxy…. Yes, this is required at Kirtland AFB.

During the site visit at Kirtland it was indicated that no pavement marking restoration would be required.

Please confirm. If pavement marking restoration is required please provide an as-built so a scope of work can be determined. Striping will NOT be required at Kirtland AFB.

Statement of Work Section 3. Sunshade Design/Construction provides Aircraft Design Sizing. This information seems applicable if we were designing a need sunshade only. Since we are only re-installng an existing sunshade please confirm that this information is not relevant to the contractor. This information is not necessarily relevant to the contract but gives sizes as a reference.

Does the government have a geotechnical report for this area? The Government does not have any geotechnical report for this area.

Statement of Work Section 3.2 states that the structure shall be built to mitigate bird roosting and nesting within the shade structure. Is netting beneath the fabric required? Yes, The Government is requiriung bird nesting mitigation. Netting holes will be no larger than 3/4".

To property quantify the extent of the sunshade demo and re-installation as-builts of the existing sunshades are needed. Please provide as-builts so that pricing can be prepared. Currently there are no existing as‐builts on file.

Statement of Work Section 2 Description of Work requires airfield pavement marking removal and striping if layout design requires relocation of aircraft. We do not know if the layout will result in relocation of aircraft as we do not have any information on placement of the sunshades. We would need the government to tell us whether the placement will result in the relocation of aircraft for bidding purposes and provide a drawing showing required re-striping. Please provide or indicate that no striping is required. Striping will be required at Laughlin AFB. Specification for striping are in UFC 3‐260‐01.
