Airport Barricade Placement Best Practices for Active Airfields
Correct airport barricade placement on active airfields requires FAA-compliant, frangible equipment installed strictly in accordance with the approved Construction Safety and Phasing Plan (CSPP). Barricades must stay outside Object Free Areas, form a continuous unbroken line, carry the required lighting during night operations, and be inspected at the start of every shift. Deviations from the approved placement – even briefly during repositioning – can trigger FAA enforcement action and halt flight operations.
Active airfield construction is one of the most tightly regulated work environments in the construction industry. Barricades that would be standard on a highway job site aren’t appropriate on an active airfield. The wrong equipment, or the correct equipment misplaced even by a few feet, can encroach on protected airspace zones, obstruct pilots’ sightlines, and trigger FAA enforcement action that suspends the entire project.
This guide covers the FAA standards, CSPP requirements, Object Free Area rules, frangibility requirements, lighting standards, and inspection protocols that govern airport barricade placement on active airfields – so every placement decision on your project is made with the full picture in mind.
Why Barricade Placement Matters on Active Airfields
On a standard construction site, a misplaced barricade is a compliance issue. On an active airfield, it can be an aviation safety incident.
Airfield construction zones operate adjacent to – and sometimes within – areas used by taxiing aircraft, ground vehicles, and runway operations. A barricade placed inside the Object Free Area (OFA) can trigger a Notice to Air Missions (NOTAM) and halt runway operations immediately. Equipment that obstructs the line of sight between pilots and taxiway guidance signs creates navigation confusion at the worst possible time.
Non-frangible barricades in areas where aircraft could strike them pose hazards far more serious than those in the construction zone itself.
Placement errors on active airfields can result in:
- FAA enforcement action and formal project suspension
- NOTAM issuance that halts or restricts active runway and taxiway operations
- Runway incursion incidents if barricade gaps are misread as passage points
- Contract termination for CSPP non-compliance
Airport work zone safety isn’t just about protecting workers on the ground; it’s about protecting aircraft, passengers, and the integrity of the entire airfield operation.
FAA Requirements That Govern Barricade Placement
The primary federal standard for airfield construction safety is FAA Advisory Circular 150/5370-2G. This document sets out the guidance for all construction activity on active airfields, including specific standards for airport barricade placement.
Key requirements under AC 150/5370-2G include:
- All barricades used on active airfields must be low-profile and frangible – designed to break away on aircraft contact without creating dangerous projectile hazards
- Equipment must not penetrate the Obstacle Free Zone (OFZ) or Object Free Area (OFA) during active operations
- All barricade placement must be documented in the approved Construction Safety and Phasing Plan (CSPP) before any equipment is positioned on the airfield
- Retroreflective orange and white markings are required on all active airfield barricades for daytime visibility
- Lighting is required during nighttime operations and periods of reduced visibility
State aviation authorities may impose additional requirements on top of the federal baseline, so it’s best to always verify current state requirements for the specific airport before procurement. When in doubt, contact the airport authority directly, as they are the on-the-ground enforcement authority.
Understanding the Construction Safety and Phasing Plan (CSPP)
The Construction Safety and Phasing Plan is the FAA-required document that governs every aspect of construction activity on an active airfield. It’s not a general safety plan – it’s a detailed, FAA-reviewed document (like this sample plan published by the FAA) that specifies exactly where work can occur, when, and under what conditions. For further clarity and as a guideline on how a contractor will comply with the CSPP, the Safety Plan Compliance Document (SPCD) must also be compiled and approved by the airport operator.
For airport barricade placement, the CSPP is the controlling document. It specifies:
- Approved work zones and their exact boundaries
- Permitted barricade locations, including specific placement coordinates relative to taxiway edges and runway safety areas
- Approved construction access routes and the gates or removable sections that serve them
- Phasing sequences – which zones are active when, and how barricade placement changes as the project progresses
There is no field improvisation on an active airfield. All airport barricade placement must conform exactly to the approved CSPP. Any change to barricade placement – even a temporary repositioning during a work phase – must be submitted to and formally approved by the airport authority before it happens.
Contractors must keep a current, approved copy of the CSPP (and SPCD) on-site at all times. FAA inspectors can request it without notice, and the inability to produce it is itself a compliance failure.
What Is an Object Free Area (OFA) and Why It Matters
The Object Free Area (OFA) is the FAA-designated clear zone around runways and taxiways that must remain free of all objects – including construction equipment, materials, vehicles, and barricades – during active flight operations. It can be further divided into the Runway Object Free Area (ROFA), the Taxiway Object Free Area (TOFA), and the Obstacle Free Zone (OFZ), which is the three-dimensional volume of airspace protecting the transition to and from the runway, where the same rules apply.
OFA dimensions are not universal. They vary based on runway classification, runway design code, and the specific aircraft types using the facility. Before any airport barricade placement begins, verify the OFA boundaries for your specific airfield from the current Airport Layout Plan and the approved CSPP. Do not rely on general OFA dimensions from other projects, as they may not apply to a new project.
Key OFA rules for airport construction barricades:
- No barricades, equipment, or materials may be placed within the OFA during active operations under any circumstances, except for fixed frangible navigational aids (NAVAIDS) required for air traffic
- Unapproved encroachment on the OFA – even briefly during equipment repositioning – can trigger a NOTAM and halt runway operations until the encroachment is cleared
- OFA boundaries must be identified and marked on your site map before the first barricade is placed
- Coordinate any work that approaches the OFA boundary with the airport operations center and the CSPP requirements
The OFA exists because even low-profile, non-frangible equipment in this zone poses an unacceptable risk to aircraft during takeoff, landing, and taxiing. Any temporary barricades that are allowed in the area must be highly reflective, frangible, and pre-approved and coordinated with the appropriate authorities.
Pre-Placement Planning for Airfield Barricades
Placement on an active airfield requires more pre-work than any other construction environment. The sequence below should be completed before the first barricade is moved into position.
It’s important to review the approved CSPP and all site drawings in detail, and to understand exactly where barricades are permitted, the required standoff distances from taxiway edges and runway safety areas, and the phasing sequence for the project. Identifying all OFA boundaries, taxiway edge lines, hold short lines, and runway safety areas on a working site map is essential for a smooth and compliant work zone. Clearly marking these boundaries allows crew leads to reference them during setup without relying on memory.
Coordinating placement timing with the airport operations center is a must. Barricade setup and repositioning must be scheduled around active movement areas, so specific time windows will likely be assigned. Never assume a window is open without confirmation! Once the window is confirmed, conduct a pre-placement walkthrough with the airport safety officer before any setup begins. This walkthrough confirms that the planned placement matches the CSPP and that no site conditions have changed since the plan was approved.
Lastly, verify that all barricade equipment has been inspected and carries current frangibility certification documentation. Non-compliant equipment cannot go on the airfield, regardless of schedule pressure, so getting it right the first time saves a lot of headaches.
Runway and Taxiway Barricade Placement Guidelines
The placement of active airfield barricades along runway and taxiway edges is governed by specific standards that go beyond general construction zone practice. The stakes – and the precision required – are significantly higher.
Barricades must define a clear, continuous boundary between the construction zone and active movement areas, as pilots and ground crew use barricade lines as visual references. Ambiguity in that boundary is a safety failure.
- Place barricades perpendicular to the taxiway or runway edge. Angled or irregular placement can mislead pilots about the actual boundary of the construction zone
- Maintain minimum clearance distances from runway and taxiway edges exactly as specified in the CSPP. These distances are calculated based on the aircraft types using the facility and are not negotiable
- Never position barricades in a way that obstructs runway threshold markings, taxiway centerline markings, or taxiway guidance signs. Pilots depend on these references for navigation, so obscuring them creates an immediate hazard
- Use high-visibility orange-and-white retroreflective markings on all airfield construction barricades. FAA-compliant barricades must be visible from the required advance distance under all lighting conditions
Spacing and Gap Requirements for Airfield Barricades
Gaps in airport barricade lines are not a minor deficiency on an active airfield. A gap large enough to be interpreted as a taxiway passage can direct an aircraft into a live construction zone, turning such gaps into a potential incursion hazard.
To prevent incursions from improperly interpreted barricade placement, airfield barricades must form a continuous, unbroken line along the entire work zone boundary. There should be no gaps that could be misread as a passage or opening by pilots or ground crew!
As a rule of thumb, the maximum gap between adjacent barricade panels should not exceed the width of the narrowest aircraft using the taxiway. In practice, this means continuous interlocked panels with no visible openings, except for an appropriately sized gap if necessary. Spacing must be consistent across the entire barricade line. Irregular gaps – even if each individual gap is small – create visual confusion and increase the risk of incursion.
Gated access points serve as transitions between the Air Operations Area (AOA) and construction zones, and these gates are strictly controlled and must be in the closed and secured position whenever [construction] vehicles are not actively transiting the access point. Temporarily placed low-profile airport barricades (generally paired with flashing hazard lights) are the optimal means of delineating routes to and from these access points. The same rules apply to the barricades leading up to access points as they do anywhere else – frangible, appropriately spaced, and highly visible.
If a gap is visible in your barricade line, it needs to be closed before operations resume. Report it to the airport operations center if it occurred outside of a planned setup window.
Lighting Requirements for Airfield Barricades
Visibility requirements for airport barricades remain active 24/7. All airfield construction barricades must be lit during nighttime operations and whenever visibility is reduced by weather, fog, or low-light conditions.
Required Lighting by Application
- Red steady-burning lights are required on barricades that mark closed taxiways, runways, or other areas off-limits to aircraft and ground vehicles. These are the primary closure markers and must be visible from the required advance distance
- Flashing amber lights may be used on construction equipment, supplemental markers, and to delineate the edges of the construction zone perimeter
- All lighting must remain operational throughout the entire shift. Assign a designated crew member to inspect all barricade lights before dusk and after any significant weather event
- Solar-powered units are common on active airfields because they eliminate power cord hazards. Verify charge levels and backup battery status daily – a solar unit that ran down overnight is a non-functional light at the start of the next night shift
A barricade with a non-functional light during nighttime operations is a non-compliant barricade. It must be corrected immediately and reported to the airport operations center, so do not wait until the next scheduled inspection!
Frangible Barricade Requirements for Active Airfields
Frangibility is the single most important equipment specification for airport barricade placement on active airfields. It is not optional and not a secondary consideration – it is an FAA requirement in any area where aircraft are present.
A frangible barricade is designed to break down and collapse on aircraft contact, dissipating impact energy rather than concentrating it. This design reduces the risk of aircraft damage and injury to the flight crew when an aircraft departs a taxiway or runway edge.
The FAA requires frangible equipment in all areas on an active airfield where aircraft contact is possible, including along taxiways, near runway edges, and on aprons. Non-frangible, rigid barricades are prohibited in Object Free Areas and on active movement surfaces under any circumstances.
Frangibility is not self-certified by the contractor. It must be verified through manufacturer certification documentation for each specific barricade model before deployment, and you should request and retain frangibility certification documentation for every barricade type you plan to deploy. FAA inspectors can request this documentation, and failure to produce it constitutes a compliance failure.
When evaluating FAA-compliant barricade options, verify that the certification covers the specific application – not just a general claim of frangibility. Low-profile design and frangible construction work together; a barricade that is frangible but still too tall violates requirements.
For a deeper review of FAA equipment compliance requirements, see OTW Safety’s guide to FAA-compliant barricade requirements.
Barricade Inspection Protocols for Active Airfield Projects
On active airfields, inspections aren’t a best practice – they’re a requirement. FAA audits of active construction projects regularly include requests for shift-by-shift inspection records, and if those records don’t exist, the project is non-compliant regardless of whether the barricades are actually in the right place.
- Inspect all barricades at the start of every shift before operations resume. This means before any construction activity begins, not concurrent with it
- Check for displacement caused by overnight ground crew activity, vehicle movement, weather, or wind. A barricade that was correctly placed at the end of the previous shift may not be in the same position at the start of the next one
- Verify that all lights are functional and positioned correctly. Replace any units with dead batteries or malfunctioning lights before the shift begins
- Document inspection results for every shift – date, time, inspector name, findings, and any corrective actions taken. This documentation is your compliance record and your protection in the event of an FAA audit or incident investigation
- Report any barricade displacement or lighting failure to the airport operations center immediately, even if it occurs mid-shift. Do not wait until the next scheduled inspection window
Common Barricade Placement Mistakes on Active Airfields
Most airport barricade placement failures follow predictable patterns. Understanding them is the most direct path to avoiding them.
- Placing barricades inside the OFA boundary, even briefly during setup. There is no grace period for OFA encroachment on an active airfield. Any encroachment at any point during the shift is a violation that must be reported to airport operations immediately. Construction equipment on a closed runway or taxiway must be coordinated with the airport operations center.
- Using non-frangible equipment in areas where aircraft contact is possible. If a barricade doesn’t have current frangibility certification, it doesn’t go on the active airfield.
- Gaps in barricade lines that could be interpreted as taxiway passages. Every gap is a potential incursion risk, so barricade lines on active airfields must be continuous and unambiguous.
- Failing to notify airport operations before repositioning barricades mid-project. Any placement change – even moving a barricade a few feet – requires coordination with airport operations and must conform to the approved CSPP.
- Missing or non-functional lighting during night operations. One dead light on a closed taxiway barricade is an FAA violation and a navigation hazard. Pre-dusk inspections are mandatory.
- Deviating from CSPP-approved placement without a formal amendment. The CSPP is the controlling document, and field improvisation on an active airfield is not permissible under any circumstances.

Frequently Asked Questions
What type of barricade is required on an active airfield?
FAA requires low-profile, frangible barricades on active airfields. Frangible barricades are designed to break away on aircraft contact. They must carry retroreflective orange-and-white markings for daytime visibility and be equipped with the required warning lights for nighttime operations. The specific barricade type and placement must be documented in the approved CSPP for the project.
What is the Object Free Area (OFA), and can barricades be placed in it?
The Object Free Area is the FAA-designated clear zone around runways and taxiways that must remain free of all objects during active flight operations. No barricades, construction equipment, vehicles, or materials may be placed within the OFA at any time during active operations. OFA dimensions vary by runway classification and must be verified from the current Airport Layout Plan and the approved CSPP for your specific project.
What does frangible mean in the context of airport barricades?
A frangible barricade is designed to break away upon aircraft impact rather than resist it. This breakaway design reduces the risk of aircraft damage and injury when an aircraft departs a taxiway or runway edge and contacts a barricade. FAA requires frangible equipment in all areas on an active airfield where aircraft contact is possible. Frangibility must be verified through manufacturer certification documentation – not assumed based on the barricade’s material or appearance.
How often must airfield barricades be inspected during construction?
Barricades must be inspected at the start of every shift before any construction operations resume. Inspections must check for displacement, lighting functionality, and conformance with the CSPP-approved placement. All inspection results must be documented with date, time, inspector name, findings, and corrective actions. FAA audits can request these records for any shift during the project.
What happens if the placement of barricades violates the CSPP?
A CSPP violation on an active airfield can result in immediate project suspension by the airport authority, FAA enforcement action, and a formal Notice to Air Missions (NOTAM) if the violation creates a hazard to flight operations. In serious cases, contract termination is possible. Any deviation from CSPP-approved barricade placement – even a temporary one – must be reported to the airport operations center immediately, and a formal amendment must be submitted before any non-conforming placement continues.
The Bottom Line
Airport barricade placement on active airfields is subject to a different standard than in any other construction environment. The FAA requirements are specific, the CSPP is the controlling document, and there is no field improvisation. Every placement decision – where, when, what equipment, and how it’s configured – must be coordinated, documented, and compliant before a single barricade is moved into position.
Get the pre-placement planning right, verify the frangibility documentation before equipment goes on the airfield, and inspect every shift and document the inspection. And, when anything changes – in the field, in the phasing, or in the layout – notify airport operations before acting, not after!
