Keep temporary airport signs inside the airport’s existing wayfinding system rather than treating construction signs as a separate graphics project. Before work starts, document the current route network, name every affected destination, assign responsibility for each message, and test the passenger path in the field. At every phase change, preserve an unbroken chain from arrival point to destination, using the same terminology, colors, letter-height logic, and graphic treatment as permanent signs. Increase visibility where construction makes the route harder to understand, and select sign materials for the time they must remain in service.
This approach follows the Federal Aviation Administration’s AC 150/5360-12F, Airport Signing and Graphics (issued September 26, 2013 and listed as active) and AC 150/5360-13A, Airport Terminal Planning (issued July 13, 2018). Those are U.S. FAA advisory materials, not a project-specific design or code approval. The airport must also check applicable ADA requirements, local building and fire codes, roadway standards, lease obligations, and its own operator standards.

Why construction breaks airport wayfinding
A terminal construction project temporarily changes the route network passengers depend on. A door may close, a checkpoint approach may move, a corridor may narrow, or a familiar destination may be reached through a different level. A sign that was correct yesterday can therefore send a passenger toward a barrier today.
The FAA describes the objective plainly: “The primary goal for temporary signs is to maintain the credibility of the wayfinding system.” It also advises, “Plan carefully to make sure the wayfinding chain is not broken during construction.” A wayfinding chain is the sequence of understandable cues that connects a passenger’s arrival point with the intended destination. It includes curbside, parking, ground transportation, entrances, ticketing, security, baggage claim, gates, restrooms, concessions, rental-car return, and the airport exit, as applicable to the project.

When one link ends at a construction fence, passengers hesitate, backtrack, ask staff for help, or follow an unofficial shortcut. The resulting confusion can create crowding, missed flights, unsafe crossings, inaccessible detours, and inconsistent instructions from employees. Temporary signs should therefore be planned as operating infrastructure, not as decoration added after a barricade is installed.
FAA terminal-planning guidance states that signage and wayfinding should be “consistent and reliable throughout the airport” and meet local and national code requirements. That principle applies during demolition, structural work, fit-out, commissioning, and the final transition back to permanent conditions.
Set the baseline before construction starts
Survey the existing route network
Start with the airport as a passenger experiences it, not only with the construction drawing. FAA signing guidance recommends walking the terminal with the plans and a camera, marking sign locations and conditions, and maintaining an information database. Record every approach to the work area from landside and airside origins, including routes used by passengers with reduced mobility.
- Photograph each existing directional, identification, regulatory, and informational sign that may be affected.
- Record the sign’s exact message, arrow direction, mounting height, illumination, letter height, color treatment, and physical condition.
- Map doors, elevators, escalators, stairs, moving walkways, checkpoints, restrooms, service counters, seating areas, and other decision points.
- Note sightlines, glare, columns, low ceilings, temporary hoarding, advertising, retail displays, queue equipment, and any object that could hide a sign.
- Measure the route used by wheelchairs, strollers, and other mobility devices instead of assuming it is identical to the shortest walking route.
The survey creates a defensible “before” condition. It also exposes inconsistent naming before construction makes the inconsistency more costly. The FAA gives an illustrative example in which one destination had six different messages at a single airport. That is an example from the circular, not a sector-wide statistic; the practical lesson is to resolve competing names before producing temporary signs.
List every origin, decision point, and destination
Build a route matrix for each construction phase. An origin is where a passenger enters the decision system; a destination is the place the passenger is trying to reach; a decision point is where a directional choice must be made. Include staff-assisted and accessible routes, not just the route shown on the architectural plan.
| Route element | Questions to answer | Record for each phase |
|---|---|---|
| Origin | Where does the passenger first encounter the changed route? | Door, curb, parking level, transit stop, shuttle stop, checkpoint, or gate-area approach |
| Decision point | Where could a passenger choose the wrong direction? | Intersection, level change, queue entrance, elevator lobby, or temporary opening |
| Destination | What exact place must remain findable? | Approved destination name, level, access condition, and operating hours if relevant |
| Constraint | What makes the route harder to read or use? | Barrier, detour, reduced width, stairs, glare, noise, queue, or limited sightline |
| Responsible party | Who can authorize and maintain the message? | Operations, project team, airline, ground transportation, communications, or contractor |
Agree on names and message hierarchy
Choose one approved name for each destination before fabrication. Decide whether the passenger needs a destination name, an action, a level, a mode, or an arrow at each decision point. Keep the hierarchy short enough to read while walking. For example, a sign might identify “Terminal 2” first, then “Departures,” then an arrow; it should not alternate among “Terminal Two,” “T2,” and “Main Terminal” unless the airport’s established standard deliberately uses those forms.
Document abbreviations, capitalization, translations, symbols, color meanings, level terminology, and the treatment of airline or facility names. The project team should approve a message schedule, not allow each trade or subcontractor to invent wording at the work boundary.

Assign ownership and escalation
Temporary wayfinding crosses organizational boundaries. Assign one accountable owner for the sign schedule and define how changes are approved. Operations should control the live passenger route; the construction manager should provide reliable phase dates and barrier locations; communications should align public notices with on-site messages; airlines and ground-transportation operators should validate destination names and service changes; and the sign fabricator should work from the approved schedule rather than verbal instructions.
Set a change-control rule: no barrier, door closure, checkpoint move, or route opening becomes operational until the affected sign set has an owner, an installation time, and an inspection time. Keep a dated record of who approved each change.
Design temporary signs as part of the permanent system
Match the airport’s graphic standards
Temporary signs should look and read as though they belong to the airport. Keep letter height, terminology, color coding, arrows, symbols, spacing, mounting conventions, and illumination consistent with permanent signs wherever the environment permits. Consistency helps passengers trust a temporary message instead of dismissing it as an unofficial notice.
Construction can justify a more visible treatment, but not a different visual language. If a detour is longer, noisier, or visually cluttered, increase sign frequency, size, contrast, illumination, or mounting prominence in accordance with the airport’s standards. Do not compensate for poor placement by adding arbitrary colors or competing type styles.

| Placement | Predictable mounting height and decision-point positioning | Move or duplicate a sign when hoarding, queues, or retail displays block the normal location |
| Illumination | Airport-approved brightness and maintenance approach | Provide additional illumination where temporary walls or night work reduce visibility |
Choose materials for the service duration
Select a temporary sign material and mounting method for the expected duration, exposure, handling, and update frequency. A message needed for a single overnight closure has different durability requirements from a panel that will remain through several months of phased work. The material must remain legible, stable, cleanable, and secure for the entire planned period.
Before ordering, define whether the sign will be indoors or outdoors, exposed to weather or cleaning chemicals, moved between phases, illuminated, or repeatedly updated. Include removal and storage in the plan. A sign that curls, fades, becomes scratched, or loses its footing undermines credibility even if its wording is correct.
Portable sign stands can help display directional content, but a stand by itself does not make a sign airport-compliant. The message, location, stability, accessible clearances, visibility, and construction context still require review.

Create information zones
Place directional information where passengers make decisions and can read it without competing visual noise. FAA guidance encourages information zones that reduce competition with advertising and retail graphics. Coordinate hoarding graphics, promotional displays, queue barriers, digital screens, and temporary notices so that the directional message remains visually dominant at the decision point.

If a corridor is inherently ambiguous, coordinate with the project designer on lighting, sightlines, barriers, openings, floor-level changes, and the location of the decision point. A larger sign may be necessary, but a clearer physical route is often the more reliable remedy.
Design for the full passenger population
Account for first-time and international travelers
Passengers may not speak the airport’s primary language, understand local abbreviations, or recognize a facility from its internal project name. Use plain, consistent destination terminology and the airport’s established symbols. Avoid introducing a contractor’s shorthand, temporary room number, or colloquial label that appears nowhere else.
Check the complete sequence, not just an individual sign. A passenger should encounter the same destination name and directional logic at the curb, entrance, lobby, checkpoint approach, and final turn. Translations, where required by the airport’s policy or local law, should be managed as part of the approved message schedule rather than added informally to a single sign.
Support reduced vision and cognitive load
Review font type, size, character spacing, contrast, illumination, and sign frequency. Place signs where passengers have enough time and distance to read them, and repeat information after a turn or level change. Avoid dense instructions that require a passenger to remember several steps while navigating noise and crowds.

Protect accessible and family routes
Maintain an accessible path through every phase, including the route to elevators, accessible security lanes, restrooms, assistance points, and ground transportation. A detour that is technically signed but forces a passenger into stairs, steep grades, narrow clearances, or an inaccessible door is not a complete wayfinding solution.

Consider families with strollers, passengers carrying luggage, older travelers, and people who need more time to make a decision. Keep sign approaches and turning areas clear of equipment, cable ramps, stored materials, and queue spillback. Confirm requirements against applicable ADA standards and local building codes; FAA circulars provide planning guidance but do not replace project-specific compliance review.
Handle landside roadway work separately
Drivers approach at higher speeds and depend on familiar roadway conventions. Interior terminal sign treatment should not be copied onto a roadway without review. For landside road work, FAA AC 150/5360-12F points to the Manual on Uniform Traffic Control Devices, Part 6, for work-zone sign layout guidance.
At minimum, temporary roadway signing should continue to identify the key destinations relevant to the closure or detour, including:
- Terminal
- Parking
- Rental-car return
- Airport exit
Add other destinations required by the route, such as ground transportation or a specific terminal, using the airport’s established naming. Coordinate sign spacing, tapers, lane assignments, visibility, and traffic-control devices with the responsible roadway authority and the project’s traffic-control plan. Do not use an interior-style portable sign as a substitute for compliant roadway signing.
Run a phase-by-phase operating process
Use the same controlled sequence whenever the construction route changes. The exact dates belong in the project schedule, but the decision logic should remain stable.
- Define the change. Identify the barrier, closure, opening, checkpoint move, level change, or destination relocation. Confirm the start time, expected duration, and conditions that would reverse it.
- Rewalk the passenger route on plans. Trace each affected origin to each destination, including accessible alternatives, employee-assisted paths, and landside approaches.
- Rewalk it in the field. Check actual sightlines, noise, lighting, queue behavior, temporary walls, equipment, and the distance between decision points. Photograph the route.
- Update the message schedule. Remove obsolete arrows, approve destination names, identify new signs and duplicates, and record the owner for each location.
- Coordinate physical conditions. Align sign locations with hoarding, doors, barriers, fire egress, elevators, accessible clearances, retail leases, and security requirements. Resolve conflicts before fabrication.
- Fabricate and install. Use the approved graphic standard and material selected for the planned service duration. Install signs before the route changes, not after passengers encounter the closure.
- Inspect at opening. Walk the route as a first-time passenger. Verify that every cue is visible, legible, correctly oriented, securely mounted, and consistent with the next cue.
- Monitor and correct. Log complaints, staff observations, crowding, missed turns, damaged signs, and route changes. Correct the physical or message problem rather than adding uncoordinated handwritten notices.
- Close or advance the phase. When the next phase begins, remove signs that now contradict the route, move reusable signs to approved locations, and update the database and drawings.
Inspect wayfinding in the field, not only on drawings
Use a repeatable inspection route
Carry the current plans, sign schedule, camera, and a route checklist. Start at each passenger origin and travel to the destination without relying on local knowledge. At every decision point, ask whether a first-time traveler can identify the next action before reaching the turn.
Recommended Free Tools
- Is the sign visible from the required approach distance?
- Is the arrow aligned with the actual path, not merely the planned path?
- Does the destination name match the preceding and following signs?
- Is the sign readable at walking speed and under current lighting?
- Are queues, advertising, columns, equipment, or construction personnel blocking it?
- Does the route remain accessible, wide enough, and free of trip hazards?
- Does the next sign appear soon enough after a turn or level change?
- Does the route end at the intended destination without an unexplained gap?
Maintain a wayfinding information database
For each sign, store a unique identifier, location, message, direction, phase, mounting method, material, installation date, responsible owner, inspection date, and removal or revision status. Attach photographs and note defects. A database prevents a phase change from leaving behind an obsolete arrow and lets operations identify every sign affected by a destination-name change.

Keep the database synchronized with the construction schedule. A sign can be physically present but operationally wrong if a door, checkpoint, airline counter, or shuttle stop has moved.
Use passenger feedback carefully
Staff reports, accessibility observations, airline feedback, and passenger comments can reveal problems that a drawing review misses. The FAA suggests passenger-satisfaction surveys as one possible evaluation method after work. The reviewed FAA guidance does not provide a current construction-specific success metric or numerical target, so establish project-specific measures only when the airport can define and collect them consistently.
Common failure modes and practical fixes
| Failure mode | What passengers experience | Fix |
|---|---|---|
| Signage stops at the hoarding line | The passenger reaches the work boundary with no next instruction. | Extend the chain beyond the barrier and verify the next cue from the passenger’s actual approach. |
| Several names for one destination | Passengers wonder whether two labels refer to different places. | Approve one destination name and replace conflicting messages across the full route. |
| Temporary signs use a new visual language | Passengers cannot tell whether a notice is official or promotional. | Match permanent colors, typography, arrows, symbols, and mounting logic. |
| Signs are installed after the closure | Passengers encounter a barrier before receiving instructions. | Install and inspect the complete detour before changing the route. |
| Architectural confusion is left to signs | Extra arrows accumulate at an inherently ambiguous corridor. | Coordinate physical changes—openings, lighting, barriers, and sightlines—with the design team. |
| Accessible route is treated as an afterthought | Wheelchair users or families are directed to stairs, narrow paths, or blocked elevators. | Map, sign, and inspect the accessible route independently for every phase. |
| Roadway and interior conventions are mixed | Drivers receive signs that are too small, late, or unfamiliar for vehicle speeds. | Use the applicable roadway work-zone standards and coordinate with the traffic-control plan. |
| Obsolete signs remain in place | Two arrows point to different routes after a phase change. | Use a removal checklist, update the database, and inspect from every approach. |
Plan closeout as carefully as the temporary phase
Construction is not complete from a wayfinding perspective when the last barrier moves. Remove temporary signs that no longer describe the route, restore permanent signs, and check that repairs, new walls, lighting, doors, and furniture have not created fresh ambiguities.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesWalk the finished passenger route from every relevant origin. Confirm that permanent signs support the improved layout, that old directional cues have been removed or corrected, and that accessible routes are equally clear. Update as-built records and retain the temporary sign history so future projects do not repeat resolved inconsistencies.
Use the airport’s chosen feedback method—such as passenger surveys, staff reports, or accessibility reviews—to evaluate the finished system. Treat the result as an operational review rather than a claim of compliance by itself. Compliance remains subject to the applicable codes, standards, and airport approvals.

- Temporary signs match permanent graphic standards.
- Letter height, contrast, illumination, and frequency reflect the actual disruption.
- Materials and mounting methods suit the expected duration and environment.
- Information zones limit competition from advertising and retail graphics.
- Roadway work follows the applicable traffic-control and work-zone requirements.
- Signs are installed before closures and inspected from passenger approaches.
- The sign database includes locations, messages, photos, owners, and revision status.
- Obsolete signs are removed at each phase transition.
- Final permanent signing is checked after construction and evaluated through the airport’s chosen feedback process.
What the FAA guidance does—and does not—decide
FAA AC 150/5360-12F provides a framework for terminal and landside signing, including construction-period continuity, field survey, temporary-sign visibility, and roadway context. FAA AC 150/5360-13A adds terminal-planning considerations for passenger diversity, terminology, spacing, maintenance, fabrication, graphic standards, and code compliance.
Neither circular supplies a location-specific sign schedule, a construction safety plan, a universal sign size for every terminal, a product ranking, or a current numerical performance target for temporary wayfinding. The airport and project team must translate the guidance into approved drawings, schedules, inspections, and code reviews for the actual facility.
Bottom line
Clear airport wayfinding during terminal construction comes from managing the temporary route as a controlled extension of the permanent system. Survey the existing network, preserve an uninterrupted passenger chain, use consistent messages and graphics, design for accessibility, separate roadway treatment from interior treatment, inspect every phase in the field, and close out the temporary system deliberately. The result is not simply more signs; it is a route passengers can understand and trust while the terminal changes around them.
