Vdc Application Case Study: North Zealand Hospital Project Collaboration

Background

The New North Zealand Hospital will be the result of consolidating the three existing hospitals across the region and is part of Denmark’s healthcare consolidation programme which includes the redevelopment of 7 hospitals. The New North Zealand Hospital is the 3rd major healthcare building to be awarded to Ramboll as part of this consolidation programme. ’ The hospital will have a capacity of 700 beds and serve over 310, 000 people. Only 4 storeys tall, the bottom half of the building will cover diagnosis and treatment facilities, while the top half will shelter ‘a ribbon of wards surrounding a roof garden’. The design is flexible enough for future changes and shift in function.

Project

The case presented in this chapter is based on personal experience and involvement with one of the most complex VDC projects in Denmark. ‘Following a 12 month intensive international design competition, the Architectural consortium of Herzog & de Meuron/Vilhelm Lauritzen Arkitekter were awarded the contract to design the New North Zealand Hospital in Hillerød, Denmark and we are delighted to be named the engineering services and project management consultant for this project. ’ The design is a low-rise, clover-shaped structure, maintaining human scale. The roof garden above the diagnosis and treatment floors, with access from the bed wards, makes it an inviting facility for patient rehabilitation.

Process

For this specific project, the software used includes Revit, Dynamo and Navisworks setting up the VDC method for future input. The 3D model was created in Revit, which allows quantities and element specifications data to be stored together with the geometry.

In a project of this scale that requires a lot of repetitive tasks, we focus on implementing Dynamo since it enables us to control tens of thousands of components and elements at once. We implement workflows such a Revit-Dynamo-Excel, being able to export element parameters directly to Excel, overriding data in Excel and then exporting it back into Revit, which speeds up the process. Navisworks Manage fulfills the clash detection operation and is indispensable to VDC. Real value comes from avoiding construction problems on site.

As a student working on the project, my responsibilities are project exchange with other companies, and auditing the health and consistency of the Revit model. This is, at the moment, very important since latest decision were focused on turning the entire BIM model 90% accurate, meaning every piece of equipment and furniture is included in the model. Unofficially, it is the most advanced project in Denmark at the moment due to LOD.

Examples of work completed are Quality Assurance of Revit models, creating IFC and WC exports for coordination and clash rendition. Occasionally, I export federated Enscape model, which we review using VR as a visual perspective to understand the scale of the space. Another example is submitting pristine models for tender and scrutiny, with only applicable information attached.

What resulted was a BIM model 90% quantifiable and automated. There is no final price available since the project was recently submitted for bidding. The details of the Revit model supply the platform to turn the currently 3D model into a 5D model at a future time.
