1. General

1.1 Purpose

This Statement of Work (SOW) describes the objectives, scope, and requirements for electrical conduit reattachment services at the Denver International Airport Air

Traffic Control Tower (DEN ATCT). The Federal Aviation Administration (FAA) requires a qualified contractor to furnish all labor, materials, equipment, and supervision necessary to perform diagnostic inspection, risk assessment, and reattachment of electrical conduit that has become detached from its support structure and is resting on Heating Ventilation Air Conditioning (HVAC) ductwork within the Cable Access / Junction Level crawl space.

1.2 Background

The DEN ATCT Cable Access / Junction Level contains seven individual electrical conduit runs (originating from panels ELPT3-1 and CLPT3-CAB) sharing common strut-channel supports along the outer perimeter of the crawl space. The affected conduit runs originate at Penetration #1 on the upper east wall, traverse the outer perimeter resting on HVAC ductwork at three identified contact points (Contact

Point 1, Contact Point 2, and Contact Point 3), and terminate at Penetration #2 at the lower southwest area. A third penetration (Penetration #3) passes vertically into the

Control Area Building (CAB) floor. The detached/collapsed section totals approximately 60 feet. At the contact points, the conduit is in direct and sustained contact with the HVAC ductwork, creating a risk of conduit stress, deformation, and potential internal wiring damage — particularly at the ends where pinching may have occurred.

The physical extent of the conduit runs requiring reattachment is known. The condition of the internal wiring and the degree of stress or damage at the conduit contact and pinch points are not known and will be assessed by the contractor prior to work. The Cable Access Level crawl space constitutes a confined space and is accessed via the Access Door on the north side of the facility.

Note: The conduit run count, contact point count, penetration locations, and approximate run length above are drawn from the FAA trip report and accompanying facility drawing/print (06 May 2026), included as Attachment A. These figures are adopted as the working basis for this SOW. The Contractor's Phase 1 Site Survey

(Section 2.1, Section 5.2) must field-verify these figures and flag any discrepancy found. The Work Method Plan (Section 2.1, Section 5.4) must be adjusted if field conditions differ materially. Total conduit weight is assumed at approximately 2,000

FAA Procurement | Conduit Reattachment SOW | Page 5 pound (lb) for design and planning purposes throughout this SOW (the trip report's field estimate of 400 lb, should be disregarded); this figure should likewise be field-verified during Phase 1, and the Work Method Plan's hardware design must be adjusted if the verified weight differs materially from 2,000 lb.

1.3 Applicable Documents and Standards

The contractor must perform all work in accordance with the following, as applicable:

● National Electrical Code (NEC) – current adopted edition

● National Fire Protection Association (NFPA) 70 – National Electrical Code

● FAA Order 6000.15 – General Maintenance Handbook for National

Airspace System Facilities

● 29 Code of Federal Regulations (CFR) 1910.146 – Permit-Required

Confined Spaces (General Industry)

● 29 CFR 1926.1203 – Confined Spaces in Construction

● 29 CFR 1910.147 – Lockout/Tagout

● Occupational Safety and Health Administration (OSHA) regulations – 29

CFR 1910 and 29 CFR 1926

● Local Authority Having Jurisdiction (AHJ) requirements

● FAA facility-specific engineering drawings for the DEN ATCT Cable

Access Level

2. Scope of Work

2.1 Work to Be Performed

Provide all labor, material, equipment, design, and supervision to perform the following tasks:

2.1.1 Site Survey and Confined Space Evaluation

The contractor must perform the following tasks for the seven known conduit runs at the DEN ATCT Cable Access / Junction Level outer perimeter, from Penetration https://my.faa.gov/org/linebusiness/ato/operations/facilities_engineering/power_services/sys_eng_team/stand_specs https://my.faa.gov/org/linebusiness/ato/operations/facilities_engineering/power_services/sys_eng_team/stand_specs

FAA Procurement | Conduit Reattachment SOW | Page 6

#1 through Contact Points 1, 2, and 3 to Penetration #2, and the vertical Penetration

#3 into the CAB floor:

● SITE SURVEY: Conduct a Site Survey within the Cable Access Level crawl space, including pictures of the existing condition (before pictures) and field-verification of conduit run count, contact point count, penetration locations, run length, and total conduit weight.

● CONFINED SPACE EVALUATION: Conduct a full confined space entry evaluation in accordance with 29 CFR 1910.146 / 29 CFR 1926.1203, including evaluation of all confined space entry requirements.

2.1.2 Diagnostic Inspection and Risk Assessment

Prior to any reattachment or movement of the conduit, the contractor must perform a thorough diagnostic inspection of the conduit runs. The purpose of this inspection is solely to assess the internal condition of the conduit and wiring, evaluate stress and potential pinch damage at the contact points, and document any pre-existing conditions — not to define the scope of reattachment work, which is already established in this SOW. Diagnostic methods are organized into two tiers based on whether they require the affected circuits to be de-energized, given that these circuits feed DEN ATCT critical and essential power (Section 1.2) and any outage is high-impact.

Tier 1 – Energized / Non-Intrusive Screening (no outage required)

The contractor must perform the following screening methods first, under normal energized operating conditions, without de-energizing any circuit:

● Infrared (IR) thermography scanning, performed while circuits are energized and under normal operating load, to detect heat signatures indicative of damaged wiring, failed insulation, or loose/degraded connections.

● Visual inspection using borescope or endoscope camera where conduit end access permits.

● Physical deformation/ovality measurement at each contact point and pinch point identified in Section 5.2, to directly quantify any conduit deformation resulting from sustained HVAC duct contact.

FAA Procurement | Conduit Reattachment SOW | Page 7

● Circuit tracing and verification: confirm and document, in coordination with the Contracting Officer Representative (COR), which specific circuit(s)/breaker(s) at panels ELPT3-1 and CLPT3-CAB correspond to each conduit run, before any further testing or work proceeds.

● Any other non-intrusive, non-destructive evaluation (NDE) method the contractor determines appropriate that does not require de-energizing the circuit.

Tier 2 – De-Energized Testing (requires outage and System

Support Center (SSC) coordination)

Time-Domain Reflectometry (TDR), insulation resistance (megger) testing, and low-resistance (DLRO/micro-ohm) testing at accessible splices and terminations all require the affected circuit to be de-energized. Because de-energizing circuits that feed DEN ATCT critical/essential power is high impact to the National Air Space

(NAS) operations, Tier 2 methods must not be performed as a blanket procedure across all conduit runs. Tier 2 testing is reserved for specific conduit runs, splices, or locations where Tier 1 screening findings indicate a suspected fault, damage, or otherwise compromised condition.

Before performing any Tier 2 testing, the contractor must:

● Document the specific Tier 1 finding(s) that justify the suspected condition and the specific run/location proposed for Tier 2 testing.

● Submit the request to the COR for coordination with SSC Technical

Operations and Air Traffic, since the affected equipment must be taken out of service for the duration of testing.

● Obtain written approval of an outage window from SSC, through the COR, before de-energizing any circuit; the contractor must not perform

Lockout/Tagout (LOTO) or Tier 2 testing absent this written approval.

● Capture baseline megger and continuity readings on the de-energized circuit before any reattachment work, for later comparison against the post-work continuity/integrity checks required in Section 2.1.4.

SSC outage-coordination lead time is separate from, and may extend beyond, the diagnostic activities in the Phase 2 window (Section 2.2). If Tier 1 screening indicates Tier 2 testing is warranted, the contractor must notify the COR immediately so SSC coordination can begin without delaying reporting on runs that do not require Tier 2 testing.

FAA Procurement | Conduit Reattachment SOW | Page 8

The contractor must document all inspection findings with photographs, thermal images, deformation measurements, TDR traces, test data, and written observations, clearly distinguishing Tier 1 (energized/non-intrusive) findings from Tier 2 (de-energized) findings. Findings must be compiled into a Diagnostic Inspection and

Risk Assessment Report (see Section 5, Deliverables) that includes:

● A description of the diagnostic methods employed (by tier) and the rationale for their selection, including the specific Tier 1 findings that justified any Tier

2 testing performed.

● All test results and findings at each inspection point, with particular attention to Contact Points 1, 2, and 3 and the conduit ends at all three penetrations.

● A risk assessment identifying any potential hazards, pre-existing damage, or conditions that may affect the safety or execution of reattachment work.

● An identification of any internal wiring damage found. Note: Internal wiring damage requiring replacement or repair is outside the scope of this SOW and may be addressed through a contract modification. The contractor must document and report such findings but must not perform wiring replacement or repair under this SOW without written direction from the Contracting

Officer.

The Diagnostic Inspection and Risk Assessment Report must be submitted to the

COR in accordance with Section 5, within the Phase 2 window described in Section

2.2. No reattachment or conduit movement may begin until the FAA has reviewed the report and the contractor has received written authorization to proceed, in accordance with the Phase 3 review period in Section 2.2.

2.1.3 Work Method Plan

Concurrent with or following submission of the Diagnostic Inspection and Risk

Assessment Report, and within the same Phase 2 window described in Section 2.2, the contractor must submit a Work Method Plan to the COR. The FAA relies on the contractor's professional expertise to determine the best and most reliable method for reattaching the conduit given actual site conditions. The Work Method Plan must include, at a minimum:

● Proposed attachment method and a description of how the conduit will be lifted, supported, and secured independently from the HVAC ductwork.

FAA Procurement | Conduit Reattachment SOW | Page 9

● Proposed support hardware specifications, including channel strut sizing, support spacing, fastener type, substrate anchorage design, and load ratings

— sized by a Colorado-licensed Professional Engineer (PE) to support the total conduit weight verified during Phases 1–2 (estimated at approximately

2,000 lb for planning purposes; see Section 1.2), with a minimum design safety factor of 2:1 over the verified weight. See Section 2.3 and Section 5.4 for the PE-stamp requirement.

● A temporary rigging and load-transfer plan describing how the conduit will be safely supported while transitioning from its current resting position on the

HVAC ductwork to the new independent supports, sized for the verified total weight.

● Proposed support spacing (the trip report recommends 10-foot intervals per

NEC as a reference point; the contractor must confirm final spacing based on its own engineering analysis of the verified conduit weight and configuration).

● Technical data or engineering rationale supporting the selected method and hardware specifications.

● A risk assessment summary referencing findings from the Diagnostic

Inspection Report, including any conditions that may affect the safety or execution of the work and the contractor's proposed mitigation measures.

● A strategic plan of action describing the sequence of work, how the HVAC ductwork and existing infrastructure will be protected throughout, and how the contractor will manage confined space entry during reattachment.

● Identification of any alternative methods considered and the rationale for the recommended approach.

● Confined space entry procedures and safety plan.

The COR will coordinate FAA/Technical Operations review of the Work Method

Plan within the Phase 3 window described in Section 2.2 and provide written approval or requests for revision. The contractor must not deviate from the approved plan without prior written approval.

2.1.4 Reattachment Work

Upon receipt of the FAA written Notice to Proceed, perform conduit reattachment

(Phase 4) in accordance with the approved Work Method Plan and the following requirements:

FAA Procurement | Conduit Reattachment SOW | Page 10

● Lift and reattach the conduit runs, removing them from contact with the

HVAC ductwork at all identified contact points and securing them independently to structural elements.

● Install conduit supports using the approved method, consistent with NEC requirements and manufacturer specifications.

● Select and install appropriate fittings, clamps, and beam clamps suitable for the conduit size, weight, and routing conditions at each location, per specifications submitted in the approved Work Method Plan.

● Anchor all support channel to structural members using fasteners appropriate for the substrate (concrete anchors, beam clamps, threaded rod, etc.), in accordance with manufacturer load ratings.

● Ensure the HVAC ductwork is not damaged, modified, or used as a conduit support surface at any point during or after the work.

● Address conduit sealing and support at all penetration points identified during the Phase 1 site survey, including fire-rated sealant where required by code.

● Replace all damaged or missing conduit hardware, supports, and fittings.

● Seal or repair conduit penetrations through fire-rated assemblies in accordance with applicable code.

● Perform continuity and integrity checks on all conduit runs upon completion.

● Remove all debris, waste materials, and contractor-owned equipment from the work site.

● Document all completed work with before and after photographs and a written completion report, including as-installed support locations and spacing.

Reattachment work must be performed with the affected circuit(s) de-energized and under LOTO, coordinated with SSC Technical Operations through the same outage-approval mechanism described for Tier 2 testing in Section 2.1.2. Unlike Tier 2 diagnostic testing — which is reserved for specific runs or locations flagged by Tier

1 screening — this Phase 4 de-energization requirement applies to all circuits being physically reattached, regardless of whether Tier 1 screening flagged a suspected condition, since physically lifting and securing the conduit inherently requires the circuit to be de-energized for personnel safety. This substantially mitigates the risk of electrical damage during Phase 4 execution.

However, if the contractor encounters a condition not identified during the Phase 2 diagnostic inspection — including additional conduit damage, an unanticipated asbestos containing material (ACM) finding, or evidence that a circuit was damaged

FAA Procurement | Conduit Reattachment SOW | Page 11 or shorted prior to or during LOTO application — the contractor must immediately stop work in the affected location, secure the area, and notify the COR (Section 2.5).

Repair or restoration of any damaged, shorted, or otherwise compromised wiring or circuit is out of scope for this SOW and will be performed separately by FAA

Technical Operations; the Contractor must not attempt such repairs under this contract. Work may not resume in the affected location until direction is received from the Contracting Office (CO), consistent with Section 6.

2.2 Schedule of Performance

The phase durations in this section are deliberately liberal to reduce schedule risk to

NAS operations; the Contractor should not assume compression of these windows is available absent written CO approval.

NOTICES: Separate Notices to Proceed will be issued for Phases 1 & 2, and Phases

4 & 5. Do not commence work required in Phase 1 or Phase 4 without a Notice to

Proceed issued by the Contracting Officer. The period of performance for Phases 1

& 2 is 28 calendar days from the effective date of the Notice to Proceed. The period of performance for Phases 4 & 5 is 37 calendar days from the effective date of the

Notice to Proceed. The total Period of Performance is then 65 calendar days.

MOBILIZATION: Before Phase 1 begins, the contractor must have all required personnel (Section 2.3) engaged — including the Professional Engineer, Certified

Rigger, and InterNational Electrical Testing Association (NETA) -certified technicians — and all required equipment (Section 4) procured and calibrated. This mobilization lead time occurs prior to the issuance of the Notice to Proceed for Phase

1 and must be reflected in the contractor's proposed project schedule.

OPERATIONAL RISK MANAGEMENT PLANNING (ORMP).: The Contractor must notify the COR at least two (2) weeks in advance of planned mobilization to allow for ORMP. ORMP is completed by SSC Technical Operations and Air Traffic prior to any work commencing. The two-week advance notice requirement is mandatory, as ORMP coordination involves multiple FAA organizational stakeholders and cannot be expedited without risk to National Airspace System

(NAS) operations. Because Phase 1 (site survey) and Phase 4 (physical reattachment) are typically separated by several weeks and involve different on-site activities and risk profiles, ORMP coordination must be performed twice: once at least two (2) weeks before Phase 1 mobilization, and again at least two (2) weeks before Phase 4 mobilization. The Contractor must notify the COR of its intended

Phase 4 start date as early as possible once Phase 3 authorization is received, so this second ORMP window does not add avoidable delay.

FAA Procurement | Conduit Reattachment SOW | Page 12

WORK-SHIFT RESTRICTIONS:

● Planning, site surveys, and coordination activities (Phases 1–2): Day shift, Monday through Friday, excluding Federal holidays.

● Physical reattachment work (Phase 4): Midnight shift only, 11:00 pm – 4:00 am.

● Any deviation from the approved work window must be pre-approved in writing by the COR.

Phase 1 –Site Survey and Confined Space Evaluation (up to 7 calendar days)

Conduct a site survey of the Cable Access / Junction Level crawl space, including a full confined space entry evaluation in accordance with 29 CFR 1910.146 / 29 CFR

1926.1203. Work under Phase 1 must be completed within seven (7) calendar days after issuance of the Notice to Proceed. Included in this allotment is, an FAA-escorted briefing, and a walk-through of the work area. Findings must be documented in the Site Survey & Confined Space Evaluation Report (Section 5).

Phase 2 – Diagnostic Inspection, Risk Assessment, and Work

Method Plan (21 calendar days)

Within twenty-one (21) calendar days of completing Phase 1, perform the Tier 1 energized/non-intrusive diagnostic screening described in Section 2.1 This 21-day window is intended to accommodate realistic turnaround for the Professional

Engineer's stamped load calculations required in Section 5.4; the Contractor should engage and brief the PE during Phase 1 so substantive review can begin as soon as

Phase 2 opens, rather than starting PE engagement after diagnostics conclude. SSC outage-coordination lead time for any Tier 2 testing is separate from this 21-calendar-day window; see Section 2.1.

Phase 3 – FAA/Technical Operations Review and Coordination

(15 business days)

Upon receipt of the Risk Assessment Report and Work Method Plan, the FAA has fifteen (15) business days to review both documents, coordinate internally, or provide requests for clarification or revision. This window is sized to allow for review by multiple offices (SSC Technical Operations, Air Traffic, and any structural/PE review of the Section 5.4 stamped calculations); it is a ceiling, not a target, and the FAA is encouraged to respond sooner where possible. If the FAA does not respond within this 15-business-day window, the submissions are deemed

FAA Procurement | Conduit Reattachment SOW | Page 13 approved. Do not commence work required in Phase 4 without a Notice to Proceed issued by the Contracting Officer.

Phase 4 – Reattachment Work Execution (not to exceed 30 calendar days)

Upon effective date of the Notice to Proceed for Phase 4 & 5, execute the approved

Work Method Plan and perform the reattachment work described in Section 2.1, subject to the shift restrictions below. Physical work is limited to the 11:00 PM –

4:00 AM midnight-shift window (5 hours), of which a portion of each shift is consumed by confined space entry protocol (atmospheric testing, attendant staging, entry logging, and egress through the approximately 30" x 30" access portal verified in Section 5.2) rather than hands-on installation. Based on an estimated 10–15 net working shifts to install independent supports across all conduit runs verified in

Section 5.2, Phase 4 is allotted up to thirty (30) calendar days from the effective date of the Notice to Proceed. This duration is deliberately liberal to absorb schedule interruptions such as Federal holidays, weather, staffing availability, or Air Traffic

Control (ATC)-driven access restrictions, without requiring a schedule modification.

If the contractor anticipates exceeding 30 calendar days, it must notify the CO in writing with an updated shift-by-shift schedule.

Phase 5 – Closeout (10 calendar days)

Within ten (10) calendar days of completing physical work, submit the Project

Completion Report with before/after photographs described in Section 5, including as-installed support locations, spacing, and continuity/integrity test results.

2.3 Personnel Qualifications

The contractor must ensure that all personnel and sub-consultants performing work under this SOW meet the following minimum qualifications, organized by discipline: All personnel must be able to pass FAA and Denver International Airport security background-checks.

Electrical

● Master Electrician, licensed in the State of Colorado, must directly perform or directly supervise all electrical work.

● All personnel working in or around the crawl space must hold current NFPA

70E "Qualified Person" status, given the presence of adjacent live critical/essential panels (ELPT3-1, CLPT3-CAB).

FAA Procurement | Conduit Reattachment SOW | Page 14

● All personnel performing or directing lockout/tagout must be "qualified persons" under 29 CFR 1910.147, not merely briefed on LOTO procedures.

Rigging and Structural

● A certified rigger, qualified under 29 CFR 1926.1425, must plan and directly supervise the temporary support and load-transfer sequence for the conduit

(Section 5.4).

● The anchor, fastener, and support hardware load calculations required in the

Work Method Plan (Section 5.4) must be prepared and stamped by a

Professional Engineer (PE) licensed in the State of Colorado, sized to the field-verified total conduit weight (or the 2,000 lb planning estimate in

Section 1.2 if not yet superseded) with a minimum 2:1 design safety factor.

Manufacturer load-rating literature alone is not sufficient; a PE stamp is required given the documented prior failure of the existing supports under load.

Confined Space

● Authorized Entrant, Attendant, and Entry Supervisor roles must be explicitly assigned per 29 CFR 1910.146, with personnel holding current OSHA-compliant confined space entry training certification per 29 CFR 1910.146 and/or 29 CFR 1926.1203.

● The confined space rescue plan (Section 5.4) must provide a non-entry

(horizontal drag) rescue capability sized to the approximately 30" x 30" access portal verified in Section 5.2; a standard vertical tripod/winch rescue system alone may not be adequate for this portal geometry, and the contractor must confirm its rescue equipment functions for the actual verified opening.

Diagnostic / NDE Personnel

● IR thermography must be performed by a technician holding American

Society for Nondestructive Testing (ASNT) SNT-TC-1A Level I or II

Thermography certification (or equivalent).

● Insulation resistance (megger) testing must be performed by a NETA-certified technician (or equivalent).

● Time-Domain Reflectometry (TDR) testing must be performed by a technician with documented experience in cable fault location, not general electrical experience alone.

FAA Procurement | Conduit Reattachment SOW | Page 15

● Low-resistance (DLRO/micro-ohm) testing, where performed under Tier 2

(Section 2.1.1), must be performed by a NETA-certified technician (or equivalent).

Supervisory

● Project Manager or superintendent must have a minimum of 5 years of experience in commercial or industrial electrical conduit installation and repair, and must hold OSHA 30-hour construction safety training, given the combined confined-space, rigging, and electrical hazard profile of this work.

Key Personnel

The following roles are designated Key Personnel for this SOW: Master Electrician, Professional Engineer (PE) responsible for the stamped load calculations (Section

2.1, Section 5.4), Certified Rigger, and the Project Manager/superintendent. The contractor must identify the specific individual filling each Key Personnel role at contract award. Copies of current licenses/certifications for each named individual

(Master Electrician license, PE license, rigger certification, NETA certification(s), ASNT SNT-TC-1A certification) must be provided prior to issuance of the Notice to Proceed. Substitution of any Key Personnel during performance requires advance written notice to, and approval by, the CO, including a demonstration that the proposed substitute meets or exceeds the qualifications specified in this section.

2.4 Place of Performance

All work is performed at the Denver International Airport Air Traffic Control Tower

(DEN ATCT / CAB), 9800 Peña Blvd, Denver, CO 80249. The specific work area is the Cable Access / Junction Level outer perimeter crawl space, accessed via the

Access Door on the north side of the facility. Per the Trip Report and facility print in Attachment A, the affected conduit consists of seven runs, approximately 60 feet total, routed from Penetration #1 (upper east wall) through Contact Points 1, 2, and

3 to Penetration #2 (southwest wall), with Penetration #3 passing vertically into the

CAB floor; the contractor must confirm these figures during the Phase 1 site survey

(Section 1.2, Section 5.2).

The Cable Access Level crawl space constitutes a confined space per 29 CFR

1910.146 / 29 CFR 1926.1203. The contractor must treat this space as a permit-required confined space unless a formal evaluation by a qualified person documents otherwise. The HVAC ducting, existing electrical infrastructure, and structural elements within the space must be protected throughout.

FAA Procurement | Conduit Reattachment SOW | Page 16

2.5 Site Access and FAA Escort

Denver International Airport (DEN) badging is not required for contractor personnel for the period of performance under this SOW. The FAA will provide escorting for all Contractor personnel requiring access to the DEN ATCT facility throughout the period of performance. The Contractor must:

● Provide the COR with a complete list of all personnel who will require site access, including full legal name and any other information required by DEN security protocols, at least two (2) weeks prior to mobilization.

● Ensure all personnel on site are accounted for and remain under FAA escort at all times while on Denver International Airport property.

● Coordinate all site access with the COR in advance. No contractor personnel may access the facility without prior COR coordination and an FAA escort present.

● Ensure personnel list is kept current. Any changes to on-site personnel must be reported to the COR immediately and prior to the individual accessing the site.

A FAA representative will be on-site during all Phase 4 (reattachment work) shifts.

During these shifts, the stop-work notification required in Section 2.1 and the incident reporting required in Section 8 must be made directly and immediately to the on-site representative, in addition to any other required notification.

3. Government-Furnished Property and Services The FAA will provide the following, at no cost to the contractor:

● Access to the Cable Access Level crawl space via the north-side Access Door during approved working hours.

● DEN ATCT facility as-built drawings and engineering documents for the

Cable Access Level, including conduit routing plans.

● A designated COR to coordinate work and answer contractor questions.

● Utility shutdown and lockout/tagout coordination as required for safe work performance.

● FAA escorts for all contractor personnel requiring access to the DEN ATCT facility throughout the period of performance.

The contractor is responsible for all other materials, tools, equipment, and consumables required to complete the work.

FAA Procurement | Conduit Reattachment SOW | Page 17

4. Contractor-Furnished Items The contractor must furnish, at a minimum, the following:

● All diagnostic and NDE equipment required for the Diagnostic Inspection and

Risk Assessment, including IR thermography camera, TDR equipment, insulation resistance (megger) tester, and borescope or endoscope camera, as applicable.

● All conduit support hardware, channel strut, brackets, beam clamps, fittings, conduit clamps, anchors, fasteners, and associated materials required to complete reattachment work, per the approved Work Method Plan.

● All tools, ladders, lifts, rigging, and personal protective equipment (PPE) including confined space-specific PPE, with all lifting and rigging equipment rated for a minimum working load of 2,000 lb (or the actual field-verified conduit weight, whichever is greater, per Section 1.2 and the Work Method

Plan).

● Atmospheric testing and monitoring equipment required for confined space entry (calibrated gas detectors for oxygen, flammable gas, and toxic contaminants).

● Confined space entry kit including retrieval/rescue equipment, communication devices, and barriers/signage.

● Waste disposal containers and materials for site cleanup.

● Digital camera or equivalent for documentation photographs.

5. Deliverables The contractor must submit each deliverable below in both Microsoft Word (.docx) and Adobe PDF format, transmitted by email to the COR, unless another format is specified. Each electronic submission must be a single consolidated file (with photographs/data embedded or attached as labeled appendices) unless file size requires separate attachments, in which case each attachment must be clearly named and referenced in a cover memo. The COR will review each deliverable for completeness against the minimum content requirements below and may reject any submission that omits a required element; the contractor must correct and resubmit a rejected deliverable within three (3) business days of notification, and such resubmission does not extend the phase deadlines in Section 2.2 unless the CO grants a schedule adjustment in writing.

non-permit-required) for the Cable Access / Junction Level crawl space, with rationale citing 29 CFR 1910.146 and/or 29 CFR 1926.1203.

● An atmospheric and physical hazard assessment specific to the crawl space, including ventilation conditions, lighting conditions, and access/egress constraints (including measured dimensions of the entry portal).

● Dated, labeled photographs of the access point, egress path, and general crawl space conditions.

● A field-verified count and description of all conduit runs, contact points, and wall/floor penetrations present, confirming or updating the working figures established in Section 1.2 (seven conduit runs, three contact points, three penetrations, approximately 60 feet total run length).

● A field-verified (or best field estimate, with method of estimation stated) total weight of the affected conduit, confirming or updating the 2,000 lb design assumption used throughout this SOW (Section 1.2); if the verified weight differs materially from 2,000 lb, the report must flag this so the Work Method

Plan's hardware design (Section 2.1.2, Section 5.4) can be adjusted accordingly.

● A preliminary confined space rescue/retrieval concept and a list of recommended atmospheric monitoring equipment and Personal protective equipment (PPE)for Phases 2 and 4.

The COR will acknowledge receipt in writing within three (3) business days. This report does not require a separate FAA approval gate before Phase 2 begins, but its verified figures (run count, contact points, penetrations, weight) must be carried forward into the Phase 2 Risk Assessment Report and Work Method Plan; a discrepancy between this report and later Phase 2 submissions must be explained in the Phase 2 deliverables.

5.3 Diagnostic Inspection and Risk Assessment Report (Phase 2)

Due within twenty-one (21) calendar days of Phase 1 completion. In addition to the content required by Section 2.1.1, the report must include:

● The field-verified conduit run count, contact point count, penetration count, and total conduit weight, carried forward from Section 5.2 (or updated with an explanation if figures changed).

FAA Procurement | Conduit Reattachment SOW | Page 20

● Raw Tier 1 diagnostic data as separate labeled electronic files: IR thermography images (native format plus a viewable format such as JPEG), deformation/ovality measurements, and borescope/endoscope photographs or video, each keyed to a specific conduit run and location.

● For any Tier 2 testing performed: the specific Tier 1 finding(s) that justified it, the SSC outage-window approval reference and date, and the resulting TDR trace files, megger test logs, and DLRO/low-resistance readings, each keyed to a specific conduit run and location. If no Tier 2 testing was performed, the report must state this and confirm that no Tier 1 findings warranted it.

● A table cross-referencing each conduit run to its origin panel (e.g., ELPT3-1, CLPT3-CAB), destination, and diagnostic findings, noting which runs received Tier 1 screening only versus Tier 1 plus Tier 2 testing.

● A written risk rating (e.g., Low / Medium / High) for each identified hazard or pre-existing condition, with supporting rationale.

Acceptance: subject to the Phase 3 FAA/Technical Operations review and written approval described in Section 2.2 and Section 5.5.

5.4 Work Method Plan (Phase 2)

Due concurrent with or following the Risk Assessment Report, within the same 21-calendar-day Phase 2 window. In addition to the content required by Section 2.1.2, the plan must include:

● Anchor, fastener, and support hardware load calculations, prepared and stamped by a Professional Engineer (PE) licensed in the State of Colorado, demonstrating that the proposed strut-channel, fasteners, anchors, and rigging are rated for the field-verified total conduit weight (or the 2,000 lb planning estimate in Section 1.2 if not yet superseded by a field-verified figure), at a minimum 2:1 design safety factor. Manufacturer load-rating literature alone does not satisfy this requirement; see Section 2.3.

● A dimensioned support-spacing plan (informed by, but not limited to, the trip report's 10-foot-interval reference) showing proposed support locations relative to the verified conduit runs and existing structural members.

● A step-by-step temporary rigging and load-transfer sequence describing how the conduit will be supported at all times during the transition from its current resting position to the new permanent supports.

● A confined-space-specific rescue plan sized to the actual access portal dimensions verified in Section 5.2, including equipment and personnel roles.

FAA Procurement | Conduit Reattachment SOW | Page 21

Acceptance: subject to the Phase 3 FAA/Technical Operations review and written authorization (or deemed approval) described in Section 2.2 and Section 5.5.

5.5 FAA/Technical Operations Authorization (Phase 3)

A Government deliverable, not a contractor deliverable. Within fifteen (15) business days of receipt of the Section 5.3 and 5.4 submissions, the COR will provide the contractor with either (a) written approval, (b) written requests for clarification or revision, or (c) no response, in which case the submissions are deemed approved per

Section 2.2, Phase 3.

5.6 Before & After Photographs (Phase 5)

Submitted with the Project Completion Report (Section 5.7). Photographs must be digital, minimum 3 megapixels, in focus, and individually captioned identifying the specific conduit run, contact point, penetration, or support location depicted and whether it is a before- or after-work image.

● Confirmation of removal of all debris, waste materials, and contractor-owned equipment from the work site.

● An as-built redline of the facility conduit routing drawing (provided as

Government-furnished information under Section 3) reflecting final support locations and any changes from the approved Work Method Plan.

● A signed statement from the contractor's project manager or superintendent certifying that the work was performed in accordance with the approved Work

Method Plan and applicable codes and standards.

6. Scope Limitations and Contract Modifications

FAA Procurement | Conduit Reattachment SOW | Page 22

The defined scope of this SOW is the reattachment and support of the seven known conduit runs identified during the Phase 1 site survey (Section 1.2, Section 2.1), as described in Section 2. The diagnostic inspection is intended to assess the condition of the existing conduit and internal wiring prior to work — it does not define or expand the reattachment scope.

If the diagnostic inspection, the asbestos (ACM) survey (Section 2.1), or Phase 4 execution itself (Section 2.1.3) reveals conditions requiring work beyond the defined reattachment scope — including but not limited to internal wiring damage, a damaged or shorted circuit, confirmed ACM requiring abatement, conductor replacement, conduit replacement, or additional conduit runs not identified in this

SOW — document and report such findings to the COR. The Contractor must not perform any out-of-scope work without written direction from the Contracting

Officer. If damage or differing site conditions are discovered that are outside the defined scope, those conditions will be evaluated by the Government and, if appropriate, addressed through a contract modification in accordance with the

Changes Clause (AMS 3.10.1-16).

7. Quality Control The Contractor must maintain a quality control program to ensure all work meets the requirements of this SOW and applicable codes and standards. The contractor must:

● Inspect all completed conduit reattachment work prior to notifying the COR of completion.

● Correct any deficiencies identified during inspection.

● Permit the COR or designated FAA representative to inspect work in progress and upon completion.

8. Safety Requirements The Contractor must comply with all applicable OSHA regulations and FAA and

Denver International Airport facility safety requirements throughout performance.

The contractor must:

● Submit a site-specific safety plan to the COR prior to commencing work, including a written confined space entry program compliant with 29 CFR

1910.146 and/or 29 CFR 1926.1203.

FAA Procurement | Conduit Reattachment SOW | Page 23

● Conduct atmospheric testing (oxygen, flammable gas, toxic contaminants) before each confined space entry and continuously monitor as required.

● Designate a qualified attendant outside each permit-required confined space during all entry operations.

● Establish and maintain a rescue plan for confined space operations, including communication procedures and emergency response contacts.

● The FAA will lock out and tag out systems, and the Contractor may add their lock out and tag out on top of the FAA’s. The Contractor must positively verify de-energization before working on any systems.

● Immediately report any accidents, incidents, or near-misses to the COR or the on-site representative during Phase 4 shifts, per Section 2.5.

● Ensure all personnel wear appropriate PPE at all times, including confined space-specific PPE.

● Comply with all Denver International Airport safety and security requirements while on airport property.

END OF STATEMENT OF WORK

Attachment A – Site Trip Report Reference

Source: FAA Trip Report, "DIA ATCT Power Infrastructure," dated 06 May 2026, from Travis Schellpeper (TID) to Christopher Bates (TSCM), including an annotated facility drawing/print of the Cable Access Level showing

Penetrations #1–#3, the HVAC duct routing, and the conduit run. The full report, including annotated photographs and the print, is attached as a separate PDF

(DEN_ATCT_CAB_Power_Infrastructure_Trip_Report_06MAY26.pdf); it is summarized here for reference only.

The conduit run count, contact point count, penetration locations, and approximate run length in Section 1.2, Section

2.1, and Section 2.4 of this SOW are adopted from this report.

Summary of findings:

● The reported condition involves seven individual conduit runs (originating from panels ELPT3-1 and

CLPT3-CAB) mounted to shared strut-channel within a crawl space inside the Junction Level crawl space beneath the ATCT CAB, accessed through an approximately 30" x 30" portal.

● An estimated 60 feet of conduit has come to rest on HVAC ducting, preventing a full collapse to the floor.

The trip report's field estimate of the weight was approximately 400 lb; this SOW instead assumes approximately 2,000 lb as the confirmed design and planning figure throughout (Section 1.2), pending field verification during Phase 1.

● Two hypotheses were raised for the root cause: (1) the…
