Airport Terminal Construction · Engineering Sectors
Passenger Terminal Building is the core transitional structure between the landside and airside of an airport, handling the full passenger journey including check-in, security screening, waiting, boarding, arrival, and baggage claim. From a general contractor's perspective, terminal construction is not merely a building project—it is a composite undertaking of "building construction + civil aviation specialty systems + municipal transportation + airside coordination," involving multiple specialty interfaces such as civil structure, long-span roof, curtain wall, Baggage Handling System (BHS), Passenger Boarding Bridge (PBB), low-voltage information systems, security screening equipment, fuel and gas supply, and Automated People Mover (APM) systems.
Regarding the rationale for development, the demand for standardization in terminal construction stems from three driving forces: first, sustained growth in global air passenger traffic, with ICAO and IATA providing clear classification and level-of-service requirements for airport design; second, Chinese contractors have undertaken numerous airport projects along the "Belt and Road" routes, necessitating the integration of Chinese standards, international standards, and host-country standards; third, as a city's gateway, a terminal's owner has multiple demands regarding image, functionality, schedule, and cost that far exceed those of ordinary building projects.
In terms of scope of application, this guide applies to new construction or expansion of civil transport airport terminals under the overseas EPC general contracting model, covering the full lifecycle from conceptual design to completion and handover. It does not apply to military airports, simple general aviation facilities, or pure cargo facilities.

The core logic of terminal design is "minimizing passenger flow, optimizing baggage flow, and maximizing commercial value." Typical zones are as follows:
| Zone | Primary Function | Key Interface |
|---|---|---|
| Landside Transportation Center | Taxi, bus, private car, rail transit connection | Municipal roads, parking structure |
| Check-in Hall | Check-in counters, self-service check-in, baggage drop | BHS origin |
| Security Screening Area | Passenger screening, carry-on baggage screening | Security equipment, information systems |
| Departure Lounge | Retail, dining, rest, boarding gates | PBB, gate systems |
| Arrival Level | Arrival corridor, baggage claim, customs and immigration | BHS terminal end, border control systems |
| Airside | Apron, service roads | Airside security, apron control |
General Contractor Key Points: The passenger flow process determines civil reservations, MEP coordination, and low-voltage cable tray routing. It is recommended to engage BHS and PBB suppliers during the schematic design phase for interface coordination to avoid costly rework later.
Terminal roofs typically employ steel space frames, trusses, or beam-string systems, with spans exceeding 100 meters. Curtain wall systems must simultaneously address daylighting, energy efficiency, wind resistance, and blast resistance requirements.
Key Control Point Checklist:
This is what distinguishes a terminal from ordinary building construction. Major systems include:
| System | Function | General Contractor Management Focus |
|---|---|---|
| BHS Baggage Handling | Baggage sorting, conveyance, storage | Coordination with civil reservations and structural loads |
| PBB Passenger Boarding Bridge | Passenger boarding | Interfacing with airside stands and FIDS |
| FIDS Flight Information Display System | Flight information display | Integration with airport AODB database |
| Security Screening Information System | Screening images, passenger information | Compliance with local civil aviation authority requirements |
| Low-Voltage Intelligent Systems | Building automation, security, public address | System integrator management |
| APM Automated People Mover | Inter-terminal passenger transport | If applicable, requires dedicated management |
Integration Recommendation: Establish a "Civil Aviation Specialty System Interface Management Matrix" that clearly defines the civil conditions, MEP conditions, information interfaces, and commissioning sequence for each system.
Overseas terminal projects often involve expansion of existing airports, making non-stop-flight construction the greatest risk source.
Core Measures:
Overseas projects must navigate the triple overlay of "Chinese standards + international standards + local standards." Recommended strategies:
---
| Comparison Dimension | Chinese National Standards (e.g., MH/T series) | International Standards (ICAO/IATA) | Local Standards (Examples) |
|---|---|---|---|
| Passenger Flow | Emphasizes efficiency and centralized layout | Emphasizes level of service and flexibility | Varies by country; often references the former two |
| Structural Design | GB series with explicit load values | No unified structural standard | Mostly adopts British, American, or European standards |
| Fire Protection | GB 50016, performance-based design | NFPA 415, etc. | Subject to local fire authority approval |
| Civil Aviation Systems | MH/T 7003, etc. | ICAO Annex 14 | Local civil aviation authority regulations |
| Green Building | GB/T 50378 | LEED, BREEAM | Local green building certifications |
General Contractor Strategy: Use local standards as the compliance baseline, international standards as technical references, and Chinese standards as cost optimization tools. When conflicts arise among the three, local mandatory requirements take priority.

Scenario 1: Pakistan Gwadar New International Airport
According to public reports, this airport was constructed by a Chinese enterprise, with the terminal design integrating local climate characteristics and modern functionality. It is a key project of the "China-Pakistan Economic Corridor." The general contractor must address challenges including high temperatures, sandstorms, and localized labor.
Scenario 2: Cambodia Siem Reap Angkor International Airport
Public information indicates that this airport was invested and constructed by a Chinese enterprise under the BOT model, with the terminal design incorporating Khmer cultural elements and meeting annual passenger throughput targets. The project involves non-stop-flight construction coordination, local civil aviation authority approvals, and interfacing with international airline operational requirements.
Scenario 3: Nigeria Lagos Airport New Terminal
According to public reports, this project was constructed by a Chinese enterprise, featuring a long-span steel structure and glass curtain wall, equipped with modern BHS and PBB systems. The general contractor must coordinate the compatibility of local standards, international standards, and Chinese equipment.
Common Challenges: Standards integration, localized labor, airside coordination, system integration, and schedule pressure.

Q1: What is the most easily overlooked interface in terminal projects?
A: The interface between BHS and civil works. The baggage system has precise requirements for structural loads, reserved openings, and MEP coordination elevations. If not locked in during the schematic design phase, later modifications incur extremely high costs.
Q2: How should structural design standards be selected for overseas projects?
A: Use local mandatory codes as the baseline. If local codes are incomplete, Chinese GB or American standards may be referenced. It is recommended to define the design standards list during contract negotiations.
Q3: How long does non-stop-flight construction approval typically take?
A: It varies by country, typically 2 to 6 months. It is recommended to communicate with the local civil aviation authority and airport operator in advance, incorporating approval milestones into the master schedule.
Q4: How should the commissioning schedule for civil aviation specialty systems be arranged?
A: It is recommended to commence individual system commissioning 6 to 9 months before completion, system integration testing 3 months before, and trial operation 1 month before. Time must be reserved for interfacing with the airport AODB and air traffic control systems.
Q5: How can terminal project costs be controlled?
A: First, optimize roof and curtain wall schemes to avoid over-design; second, balance Chinese brands with local certification requirements in equipment selection; third, lock in exchange rates and material prices in advance; fourth, minimize design changes.

1. Early Involvement: Engage civil aviation specialty consultants at the bidding stage to identify key interfaces such as BHS, PBB, and low-voltage systems.
2. Standards Checklist: Prepare a "Design Standards Applicability Checklist" specifying the standards and priorities adopted for each specialty, and submit to the owner and local approving authorities for confirmation.
3. Interface Matrix: Establish a "Specialty Interface Management Matrix" defining the responsible party for civil, MEP, and information interfaces of each system.
4. Non-Stop-Flight Plan: Prepare a dedicated non-stop-flight construction method statement in advance and establish regular coordination mechanisms with the airport operator and control tower.
5. Localized Labor: Develop a localized labor plan, with Chinese key personnel in critical positions and trained local workers in general positions.
6. Equipment Certification: Verify in advance whether Chinese equipment meets local certification requirements; select local or third-country brands when necessary.
7. Commissioning Plan: Incorporate civil aviation system commissioning into the master schedule, reserving sufficient time for integration testing and trial operation.
8. Risk Contingency: Reserve risk contingency funds in contracts and budgets for standards conflicts, approval delays, and exchange rate fluctuations.
Conclusion: Terminal construction is a typical overseas project characterized by high technical complexity, numerous interfaces, and diverse standards. The core competency of a general contractor lies not in "knowing how to build a building," but in "integrating resources, managing interfaces, and harmonizing standards." Systematizing scattered information and making hidden risks visible is the key to success. For specific standard numbers and project amounts, please refer to official documents and contract files.
