| CASE STUDY - SKANSKA USE ARTRA FM ON ROYAL LONDON HOSPITAL |
 |
|
When completed in 2012 the Royal London Hospital will be the largest new hospital in the UK. This 905-bed facility will provide London’s principal trauma and emergency centre and the city’s second largest paediatric unit, as well as 100 other specialist medical departments including the Helicopter Emergency Medical Service. The Royal London’s new building is being configured as a pair of 20 storey towers containing 6,225 rooms across 1.2 million sq ft of floor space.
The architects are part of a design and delivery team led by a principal contractor operating under a government Private Finance Initiative. The project is politically and financially complex, as well as being technically demanding.
Highly coordinated computing systems based around interoperability and “building information modelling” (BIM) have enabled the consortium to create a coherent design which minimises waste and duplication, reduces risk and allows different solutions to be explored quickly and robustly.
COST ADVANTAGES FROM THE BIM The "up-front" investment in BIM was not paid for by the customer (the UK’s National Health Service), but the consortium estimates that the BIM method should shave €93 million off the total cost of this project for an investment of just €2.7 million in additional costs. The benefits are widespread and the consortium forecasts that reuse of the BIMs data will save €375,000 on the cost of producing an operations and maintenance manual.
BIM CAD SYSTEM AutoCAD ADT was used to create the architectural model and CADDUCT was used for the MEP model.
ArtrA FM – roll over information
LINKS TO INFORMATION In parallel to the coordination checking, clash prevention and “virtual snagging” process, the Data Management Group are enriching the architectural, structural and the MEP models by links to documentation via ArtrA.
ARTRA ArtrA is used because of its ability to read any file format and its methodology of extracting the attribute values for all objects into its database. This provides more flexibility and an in depth collation of links as the process develops.

INFORMATION ON DEMAND All the attributes are in ArtrA's database, so when the operator navigates through the model, the attributes of an item will ‘pop up’ as the mouse hovers over it.
MEP attributes 'pop-up'
The user knows that the highlighted item is a 4" elbow on the Sprinkler system and which zone it is in.
SEARCH AND FIND The database can be queried and searched in many ways. In the example below where ArtrA has searched for the sprinkler system, it shows how the results can be isolated or the surrounding environment can be turned transparent for clarity.
Filtering views for clarity
LINKING DOCUMENTS Any electronic document can be linked to an item, or a series of items for fast information retrieval.
When a user clicks on an item, the object will reveal all the documents related to it - including PDF’s.
EASY TO USE
These libraries are the interface between the models & the documents and enable ArtrA users to search through a 3D model and retrieve the information that's required. By working graphically, the user is visually aware that the documents he is accessing relate to the physical component he is looking at on the screen.
COMPREHENSIVE FUNCTIONALITY ArtrA's impressive search facility enables users to find and access relevant documents even if they do not know the correct name for the part. But ArtrA can do more than just dig out documents; because it uses a BIM as its source, it can extract other information such as bills of material taken off from the CAD attributes.
Freedom to roam
ArTrA can create a link to every panel, pipe run, elbow, duct, containment, instrument etc. throughout the model. Its document searches can bring up information that is not found in a 3D model such as the paints used, or the results of corrosion monitoring etc. ArtrA is completely flexible and so allows the user to tag and include whatever is needed.

ARTRA TAGGING SYSTEM ArtrA's flexibility of allowing the addition of tags external to the CAD system opens up many possibilities. On the Royal London Hospital there are more than 28,000 partitions, in four different finishes; each needing inspection for signing off and requiring documentation. Here ArtrA's tagging system has been used to great effect for adding new information.
Searching ArtrA Tags
ArtrA will allow a new unique Tag with any amount of updateable data fields to be defined for any object. Tags can also be added to an entire selection of objects after running a search. A Tag can have any amount updateable data fields and be applied to a wide selection of items.
Users of the system can View and Edit the Tag data on-site, run searches on Tag fields and use ArtrA's functions to isolate, highlight, make transparent or hidden when reviewing the results.
The above image was created by a search on the tag data for all partitions that have been signed off. It shows that only 12 of 354 partitions have been completed and where they are. Any items selected in the search results will be highlighted in the model.
By selecting any of the partitions in the model or from the search results, the Tag data can be viewed. If the user picks any of the Tag values the edit dialog box will appear so they can be updated.
The Tag data can also be set using ArtrA
Librarian which allows ‘batch’ updates of the
information. In the example above, a new inspection date has
been set for all signed off items.
