Civil Engineering

Achieving this required a coordinated BIM model capable of detecting clashes, supporting construction sequencing, and informing safety assessments. The client also needed clear, ongoing coordination across disciplines and a robust approach to maintaining and updating project information.

We provided comprehensive BIM and documentation from LOD 200 to LOD 400 in critical areas supported by integrated civil and structural engineering expertise.

From existing design information, we produced a fully integrated BIM model with particular focus on the viaduct’s critical interfaces with live transport infrastructure. We confirmed the accuracy of the design work, detected clashes and confirmed that the design was buildable. Throughout the project, the model was rigorously maintained and updated. In addition, we supported the design and planning of temporary works and contributed to improvements in the buildability of the permanent works.

One of our team members worked from the client’s project office, enabling close day-to-day coordination with the wider project team, additionally helping support the development of construction programmes, detailed modelling of construction sequencing, and the assessment of health and safety considerations.

At project completion, the Project Director could demonstrate to their Board that collaborating with Atlas contributed to a direct project saving of close to HK$20million.

We provided full architectural, structural, MEP, and civil documentation services, working in close coordination with the client’s team. By leveraging the time-zone difference, we ensured near-24/7 progress on the documentation, delivering the test-fit package efficiently, below budget, and on schedule, giving the client a clear and reliable basis to plan the next stage of their development.

The final drawings and associated models incorporated the end-clients standards for architectural, landscape, structural, civil, and building services elements. Throughout, we developed BIM tools to support the efficient delivery of the models and drawings and incorporated relevant data for the final asset information model.

Using our flexible resourcing, we delivered a Revit LOD 200 3D solid road and services model for coordination, incorporating roads, footpaths, drains and culverts, sewers, development plots, and terrain and parkland elements.

Our civil team alone contributed to the completion of more than 2,000 as-constructed drawings and 75 LOD 300 models incorporating roadways, footpaths, car park, utilities, retaining walls, fencing and barriers. As-constructed drawings were validated against models using as-built surveys, and updated asset tags for the constructed civil elements.

The work was performed using 12D, OpenRoads, Revit, Tekla, AutoCAD and Civil3D software, and throughout the project we developed custom BIM tools to support efficient production of more than 1,000 drawings per month, meeting all rigid documentation protocols. At completion we supplied a final asset information model (AIM) with all relevant model data.

The project comprises new stations, structures including road-over-rail bridges, sections of elevated viaduct, bridge and rail tunnel portal.

The project involved major road and bridge upgrades with associated infrastructure. Our accurate and efficiently delivered as-built documentation enabled the client to meet contractual requirements and access bond and retention funds promptly.

Working in Revit across all disciplines, with Plant 3D used for MEP services, the team developed accurate as-built drawings and models from hundreds of issued-for-construction 2D drawings, 3D models, redline mark-ups and survey data. Delivered over an approximately 15-month period, the coordinated digital outputs provided a reliable foundation to support planning, coordination and delivery of the facility upgrades.

The scope included the accurate application of pavement edge detailing and pavement depth configurations to reflect the final design intent. From these coordinated models, we generated intelligent solid object representations of the completed road and car park infrastructure, ensuring all elements of the design were captured with precision.

The resulting models were developed to LOD 300, providing a reliable, information-rich foundation to support downstream coordination, documentation, and construction workflows.

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.
