Main Contractor & Builder Support

We authored the project-specific BIM Execution Plans for all disciplines and developed and managed the fully federated LOD 300 model including updates throughout delivery.

3D models and documentation were produced for every discipline, with MEPF 3D modelling extended through construction, contract administration, and post-practical completion stages. We also led 4D/5D/6D integration, and provided full clash detection, issue resolution, and design model adjustments aligned with agreed system priorities. Enscape visualisations were produced for client sign-off, and we ensured accurate tagging and metadata structuring for FM systems. Our team also supported the client with trade package development, workshop drawing reviews, schedule generation, RFI resolution and defects inspections and at project completion handed-over a fully coordinated as-built LOD 500 model ready for operational use.

At project end, the client received a well-coordinated, clash free model in roughly 60% of the time a conventional workflow would have required. This upfront efficiency provided a reliable model for construction and allowed the project to reach completion ahead of schedule.

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.

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.

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.

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

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.

dRofus database reviews were undertaken alongside collaborative workshops with the consultant team to coordinate information requirements and align design outputs with the BEP and long-term asset management needs. A flexible resourcing model enabled rapid progression of design and BIM deliverables, helping the client meet contractual milestones while maintaining quality and compliance across the project.

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 as-builts incorporated various elements of light rail infrastructure, such as building and yard services, earthworks, CRS, drainage, utilities, structure, all civil works, overhead wiring, all rail systems, earthing and bonding, architecture, landscape, fencing and gates, roadworks, signage and wayfinding.
