Infrastructure

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.

We seamlessly integrated the latest technological tools into our workflow—leveraging Grasshopper for parametric modelling, Tekla API for automated component creation, and Solibri for comprehensive quality assurance. This allowed us to transform what could have been a painstaking manual task into a streamlined, data-rich, and highly automated pipeline.

The automation and structured dataflow greatly improved project scheduling and progress monitoring, making the process more predictable and manageable for all stakeholders. The result was an exceptionally precise digital model, delivered far faster than with conventional methods.

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.

With the facility design at an early concept stage, elements of the services infrastructure layout and sizing were estimated for visualisation purposes, requiring close coordination and informed assumptions to deliver a clear and compelling representation of the proposed scheme.

By deploying a flexible delivery team, we helped the client reduce operational risk, maintain coordination across disciplines, and support efficient project delivery.

Bridge structures were also modelled using simplified geometries with appropriate levels of detail to support coordination and construction planning.

Automation tools developed from previous, comparable projects were applied to optimise resourcing, ensure consistency and accelerate delivery. The project involved the construction of a new drinking water treatment plant and transfer pipelines, increasing the city’s potable water supply capacity by approximately 60%.

Architectural elements were developed to LOD 300, while structural and MEP components were modelled for the influent pumping station and associated areas, supporting coordinated design and efficient delivery of the works.

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.

Given the scale and complexity of the facility, we utilised EdgeWise pipe modelling software to automate and accelerate the generation of accurate 3D pipe work. On completion, the coordinated model was converted into a 3D AutoCAD file, providing a reliable digital foundation for design, coordination and construction planning.

The 2.5-minute animation, produced in 14 days, focused on a specific section of pier works, visualising construction sequencing, plant and equipment operations, material movements, and the installation of beams and metallic components to support a compelling and technically accurate bid submission.

The animation incorporated Google Earth Studio topography, along with traffic detours, lane shifts and falsework details. Developed collaboratively with the client, the storyboard and final animation were delivered within a six-week programme.

As the client’s point cloud scans lacked sufficient detail to model the complex equipment and structures, we supplemented them with piping and instrumentation diagrams (P&ID), general arrangement and isometric drawings, and instrument photographs. This approach allowed us to accurately model the assets and link all 3D elements to AIM Class metadata.

Their goal was to propose a construction solution that could be fabricated off-site and built with minimum disruption to the adjoining hospital and surrounding park environment.

Using our BIM model, we deconstructed and rebuilt the design, rationalising it into regular components suitable for efficient off-site fabrication. To support the competition evaluation, we created walk-thru animations and an immersive augmented reality experience, allowing the judging panel to fully understand the proposed construction solution. We also produced detailed fabrication drawings for the steel manufacturer.

As a result, the client reduced construction costs by approximately 21% and clearly demonstrated the commercial viability of their proposal.

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.
