The firm used BIM models and workflows to optimise building design and incorporate existing structures. Voyants Solutions designed a structure and development plan that specifically accommodated the challenging requirement of keeping the existing station fully operational during construction.
Like the city of Gwalior, the railway station will be a combination of new and old. The station sits between the old city of Gwalior to the west and the new settlement to the east. The proposed design embraces the old heritage station, which remains a focal point, and adds a light-weight shell structure based on the arch of the existing building. These new modular three-dimensional arches will bring light and new life to the complex. The project designers faced unique constraints to their design since the station will remain fully operational with all platforms open during construction. Voyants Solutions determined that it could meet these specifications with a framed structure, where multiple components could be fabricated off-site and placed in position with the help of cranes. The construction team would cast the pile foundations in-situ, using auger boring and self-compacting concrete.
Voyants Solutions constructed a complete BIM model using Bentley software. They designed the structure in MicroStation and STAAD.Pro, and then created a digital engineering model in OpenBuildings Designer. The design required parametric modelling, 3D modelling, and animation. Given the parametrically controlled model, a base component was generated and informed based on site constraints.
The complete BIM model made it easy to understand design requirements and optimise project results. Sustainability was a key feature of the design. The team used building energy modelling technology to optimise natural light and minimise the heat gain of the building. By incorporating large overhangs, shading features, and natural ventilation, the firm reduced the heat gain of the building by 40%.
A team of five designers at Voyants Solutions prepared the plan set and 3D model for this project in one month. Voyants Solutions estimated labour-hour savings of 30% for this proposal and a 500% ROI for the project. Bentley software helped the organisation industrialise its BIM workflows to quickly deliver a high-quality design with a cohesive scheme.
Upendar Rao Kollu, managing director at Voyants Solutions, said: “Innovative designs need innovative applications. Bentley applications have allowed the multidiscipline team to work on a single platform and create iconic designs.”
The Voyants Solutions team succeeded in creating a visually stunning and functional design for the Gwalior Railway Station that will improve passenger-related amenities, serve as a community hub, and contribute to the economic development of the local community.
