Millar Management - UK airport security checkpoint


Millar Management provide design consultancy services for security checkpoints, baggage systems and facilities and offer architectural design services to a wide range of projects in aviation. MM’s recent client – a UK airport, provided a brief to develop a series of concept designs for the new security checkpoint, including the impact of future legislative requirements in relation to the use of both body scanners and CT X-Rays for cabin baggage. EBEA Consulting provided 3D simulation support, to validate the proposed final designs, as well as support during the transition period between the current equipment and the new one.  

Airport business need:

Future legislative changes will require UK airports to replace all conventional X-Rays with CT units for the screening of baggage, together with a requirement to increase the number of body scanners. Airport's success criteria for the project were:

  • Compliance with DfT regulation by the stipulated dates.

  • Enabling passenger growth.

  • Minimising passenger queuing to enhance the passenger experience.

  • Phased project plan to ensure adequate capacity during the works.

EBEA Consulting Solution:

In response to the airport’s business need, EBEA conducted
a comprehensive analysis of the expected performance of CT technology at the airport security checkpoint.


Based on industry best practices, we used a combination of both static and dynamic tools to ensure time and cost efficiency, while delivering a great level of detail to make informed data-driven decisions.


Based on the designs created by Millar Management, the analysis covered:

  • Validation of the expected throughput of the new CT lanes for both Summer and Winter operation.

  • Assessment of the expected queue times and lengths for:

    • The proposed final design options in both seasons.

    • The proposed construction phasing programme.


  • Validation of the proposed lane designs and expected passenger throughput for the Summer and Winter seasons (adequacy of design).

  • Identification of potential system bottlenecks and breaking points, with recommendations on:

    • Minimum levels of lane manning for peak period operations (passenger experience).

    • Body scanner provisions based on seasonality in passenger throughput (OPEX efficiency).

  • Identification of minimum operational requirements to achieve queue time business targets and maintain the queues within the dedicated areas (OPEX/CAPEX/passenger experience).

  • Validation of the final design options to meet forecast demand, provide resiliency and allow for further growth (value engineering).

  • Identification of potential risks across the most constraining phases of the proposed phasing programmes (passenger experience).
