InfraWorks models to assist with construction sequencing and planning

Autodesk Software package InfraWorks is a 3D Infrastructure planning and design tool which is being used to model specific areas of the High Speed Two (HS2) proposed route and the proposed construction sequences respectively. This paper focuses on the creation of the models, data processing, material volume reports and the benefits that these models have presented.

The models produced have created a visual platform to review the integration of temporary works and permanent works for these large areas of the HS2 Project. Video flythroughs that have been created have also provided the HS2 Project Team with a valuable tool to present the scheme to their client and for use in public consultations.

The paper discusses how the designer is using advanced software to undertake detailed planning at pre-construction stage and how this is helping to eliminate risk items, understand areas which pose the greatest risk and how risk can be mitigated. On the surface, the learning legacy of this study is the value in InfraWorks as a pre-construction tool and its potential application in future phases of HS2 and projects beyond. Additionally, it further supports the importance of high levels of care and attention at preconstruction phase to further optimise both design and construction phases through careful optioneering.

Taking the time to produce high quality outputs at this stage in the project’s life cycle can have benefits for project stakeholders across the board. The outputs described in this paper are constantly being made easier to produce through the development of software such as InfraWorks. This is an area the industry would do well to keep its attention on in the coming years.
