We developed a detailed BIM model of the proposed midfield concourse, incorporating surrounding context to accurately represent scale, interfaces, and site conditions. Building on this, we produced a three-minute 3D animation that showcased key design elements, spatial planning, and construction sequencing. Together, these services enabled stakeholders to clearly understand the proposed development, assess design intent, and confidently communicate the project vision during the competitive bid phase.

The scope included demolition, concrete profile and room layout packages, FF&E, and site fire egress drawings. In parallel, we supported time-critical tasks to maintain programme momentum while the client’s team managed site inspections and consultant coordination.

Updated Revit models and AutoCAD drawings were coordinated and issued as final as-built PDFs in line with strict documentation protocols.

Through the development of bespoke BIM tools and targeted solutions to resolve outdated and defective files, we achieved a high-volume delivery rate of over 700 as-built drawings per month, ensuring project deadlines were met.

Developed from 2D CAD information, the integrated Revit model was produced by a multidisciplinary team within a four-week programme, resolving clashes and construction challenges as the design progressed.

The coordinated BIM models were used by the main contractor during construction, while a millimetre-accurate point cloud survey informed a data-rich as-built model for digital walk-throughs and ongoing asset management. In parallel, we provided BIM training to AAHK teams in Hong Kong and Vietnam, helping build internal capability for the wider Three Runway System expansion programme.

Our scope of work involved multidisciplinary as-built LOD 350 – 500 BIM modelling for 700,000 m² of existing buildings, including the Terminal 1 main building, link bridges, aircraft loading bridges, ground transportation centre, limousine lounge and associated tunnels, north satellite concourse and skypier.

To create the as-built BIM model, the Airport Authority provided us with thousands of pieces of reference information such as as-built architectural, structural and building services drawings, photos, data schedules, point cloud and panoramic photos.

From the reference information, we created a fully federated LOD 500 as-built BIM model, incorporating architectural, structural, building services, Special Airport Systems, and associated civil/underground utilities.

During the 2-year programme our team validated over 10,000 folders, 500,000 files and 391GB of information, and created and aligned over 3,000,000 BIM geometries.

Atlas is one of few companies in the world with the expertise and capacity to take on such a large project and deliver it to the aggressive programme. We mobilised a large multidisciplinary team to fully model the terminal building in the first 3-months to meet programme requirements. We then continued with model validation against point cloud files and asset tagging.

With large volumes of architectural and engineering documentation required and a demanding programme, the client needed a partner who could deliver coordinated BIM models, detailed design outputs, and special structural analysis quickly and accurately.

We provided comprehensive architectural and multidisciplinary engineering modelling, BIM support, and documentation services across key design stages. During the structural Reference Design package, we carried out detailed analysis using Robot, SAFE, and Tedds for core elements—all designed in accordance with relevant Eurocode and British Annex standards.

Throughout the project we continuously updated the Revit model and provided full calculation reports. Despite the scale and complexity, we delivered all pre-final (85%) and final design (100%) outputs within just three weeks, enabling our client to meet their programme targets.

Atlas provided architectural Revit support across several project areas within the development from preliminary design to detailed design, ensuring clear and accurate documentation while coordinating between structural, architectural, and building services. We also prepared detailed presentation drawings that helped stakeholders visualise design outcomes and secure approvals with confidence.

Our flexible delivery model allowed the client to scale our involvement in line with project demands. With expertise in both technical documentation and 3D visualisation, we provided responsive support that streamlined coordination, accelerated stakeholder engagement, and contributed to the successful delivery of the terminal upgrade.
