BIM Improves Operations at Tokyo's Haneda Airport
Using scan-to-BIM and 3D modelling techniques, Redstack technicians created an LOD 500 as built model of Tokyo's Haneda Airport for facilities management.
The benefits of building information modelling (BIM) are not just limited to new developments - they can be implemented in facilities that are several decades old. This is quite evident at Tokyo's Haneda Airport, where Redstack has played a key role in a BIM implementation at the heavily-used transportation centre.
This project is helping to further demonstrate the usefulness of BIM at all stages in an asset's lifecycle - whether or not it was implemented at the start of the design timeline.
Bringing BIM to Haneda
Kicking off in the middle of 2015, the BIM implementation project at Haneda Airport brings in a number of different areas of this methodology. Normally, in order for a project to use the BIM process, BIM must be included in the planning stages. For a facility like Haneda Airport - which first opened in 1955, long before BIM was established - such an implementation must be done in a unique way.
This is where Redstack has been able to leverage its extensive expertise in BIM - bringing Haneda Airport into the modern age of asset management. Gabriel Baldonado, Redstack's project director for this undertaking, discussed the endeavour and how it will bring a wealth of benefits to the airport. One of the main goals of BIM at Haneda is to use the model in a facilities management capacity. This means that Redstack technicians needed to create a level of detail (LOD) 500 model - no easy feat in an airport as old as Haneda.
"That's where our technology comes in; whenever there's a building which is actually quite old, and we want to get a model of it as-built, we need to use a 3D scanner," Gabriel said. "Haneda Airport is quite a pioneering project, one which will increase BIM awareness."
How was the model created?
There are several steps involved in creating an as-built LOD 500 BIM model, especially with the Haneda Airport project; data came from two main sources - a 3D laser scanner and existing 2D architectural drawings.
Redstack technicians used a Leica 3D scanner throughout Haneda, recording data about the facility and generating a point cloud that contains measurements of everything scanned down to location on an X-, Y- and Z-axis. The scanner was able to take in a 360-degree view from multiple vantage points and stitch all the data together to form a complete representation.
While this work captured the structure as it currently exists, other specialists worked with the old architectural drawings from the construction and upkeep of Haneda Airport. Even though changes over time have made some parts of the drawings obsolete, they still provided valuable information that was essential in generating the BIM model.
Using the data from these two sources, Redstack modellers used Autodesk Building Design Suite to generate the BIM model, integrating information from the point cloud and 2D drawings. Once the model was complete, the final step was to verify the model against the actual facility.
How will BIM be useful at Haneda?
By far, the most advantageous use of the BIM model will be for further facilities management. A crucial function at any institution, facilities management is streamlined with BIM - particularly given the level of complexity involved with managing daily operations at an airport. "Most airports use the traditional way of building facilities management - this could be Excel sheets, hard-copy documents or any other original documentation - which mostly relies on 2D drawings," Gabriel noted.
BIM plus facilities management, on the other hand, provides an integrated, web-based solution for creating, integrating, building, communicating and managing information about all aspects of Haneda Airport's facilities.
In demonstrating what BIM can do in the facilities management stage, the Haneda Airport project will be instrumental in shattering people's perceptions about what the technique actually is and how it can be used.
"Normally, in the construction industry, the BIM model is used for clash detection, clash resolution and coordination - and then they archive the BIM model. And that, I think, just doesn't make sense. After construction, there's still plenty of use for that model," Gabriel said.
"We believe the BIM model has a lot more value and intelligence data for sharing information across the entire work process for airport operators. This expands the existing workflow into a new level of collaboration, coordination, simulation and visualisation processes."
