Rail

Services included federated model creation, multidisciplinary clash and issue management—including subcontractor models—operational and maintenance clearance checking, and coordination across all tunnel MEP systems and overhead electrical works.

Ongoing support was provided to the main contractor throughout federation of the sub-contractor models.

The scope covered pre-design development and design development stages, with architectural Revit models developed to LOD 350. We adapted client-supplied Revit Families to suit the specific needs of each station and produced detailed door schedules.

To support close collaboration with the delivery team, several of our team were seconded to the client’s project office for an extended period.

Support was provided through to the completion of IFC documentation, contributing to a coordinated and construction-ready design outcome.

Supporting the client’s design of the superstructure, roof and façade systems, we provided structural modelling and documentation services. Using MicroStation, we delivered a full set of reinforced concrete construction drawings. BIM services included developing 3D models in Revit and Tekla to resolve clashes and reinforcement congestion within the complex structural forms. We also assisted with reinforcement calculations for columns, beams and slabs using the client’s Robot analysis model, helping ensure buildable, high-quality outcomes within budget and tolerance constraints.

We developed the provided MEP Revit models to LOD 350, coordinated all MEP services within the scope, performed clash analysis and rectified clashes between MEP, architectural and structural disciplines. Drawings produced included individual (ISD) and combined (CSD) services drawings, and builders work drawings (SEM).

The mass rapid transit (MRT) project includes two stations, one an interchange, and the world’s first integrated four-in-one depot facility with stacked 3-level rail depot, stabling yards, workshops and multi-level bus depot.

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.

At project commencement, a detailed clash matrix was developed in collaboration with the client to clearly define tolerances and eliminate false positives. Revizto was then used to undertake clash detection and generate structured clash reports, with our team also leading the ongoing coordination meetings.

In parallel, our engineering and as-built teams—appointed under separate scopes—delivered full station models based on 2D documentation.

Team members were seconded to work full-time within the client’s project office, operating as an embedded extension of the project team and supported by a dedicated delivery team based in our operations centre.

Our on-site expat team supported the project through the design phase and into the post-contract shop drawing stage, coordinating building services and site equipment fixings with internal panels and façade systems. Delivery was governed by strict documentation protocols, with all instructions and RFIs managed in accordance with the project’s BIM Execution Plan.

We updated the model to align with civil level information, updated planting types, reorganised trees and bushes, adjusted paving types and furniture placements, collaborated with utility providers, and coordinated civil levels and the architectural team to ensure seamless consistency between interior and exterior elements. Compliance was ensured with local standards for tactile elements, including verification of paving dimensions, road, cycle paths, parking bays, and car parks.

Our integrated support ensured the successful delivery of key project milestones while maintaining the highest standards of quality and precision.

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.

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.

We were tasked with structural Revit LOD 300 modelling, production of detailed design and IFC stage drawings, and services coordination and clash detection.

Given the complexity of the 3D modelling scope, we developed efficient execution methods by introducing customised add-ins and automation tools. This significantly accelerated the modelling and large-scale updates—their effectiveness evident when frequent design changes and rework were required, enabling the team to meet tight deadlines despite the project’s scale.
