Right besides the second oldest church in the Hanseatic city of Hamburg, 22100 sqm of mixed use project development is under construction since spring 2012. 130 attractive apartments alongside office and commercial spaces will be built in three houses of 6-7 storeys. Having more than 1700 rooms and 400 shaft segments to manage, the project management of this large facility is challenged with piles of drawings, photos, test records and other documents being generated every day. To enhance efficiency in these project processes, HOCHTIEF ViCon developed an innovative production system that combines its expertise on ‘Building Information Modeling (BIM)’ with the latest technologies of mobile devices.The online interface of the system carries a 3D model of the project that is linked to an organized set of information such as project schedule, construction status, inspection results, quality assurance reports, performance indicators, photos, documents and drawings pertaining to each specific room. On site, engineers are provided with customized digital forms for recording data on hand-held devices such as iPads. Acquired data is automatically sorted into the online platform and links itself to its corresponding location in the 3D model. Such a system not only offers the possibility of monitoring the site progress in real-time but also simultaneously records as-built situation of the constructed facility. For example, pictures and test records of hidden mechanical or plumbing services in the walls can quickly be identified in the online platform and its related documentation can be referred before making any maintenance alterations. For operation and maintenance phases, such efficiency can prove to be a huge time and cost-saving advantage. Often, in many legal disputes, the lack of documentation or the inability to locate the right information at the right time is a cause of financial or legal consequence. A model-based production system enables the client to protect himself by using up-to-date and reliable information in critical times. Additionally, the system is designed with an easy-to-use interface which does not require any specialized training. It allows multiple users of the project to work together at the same time. The permission to access data can also be customized. No prior knowledge of BIM or any specific software is needed to operate this system; opening the opportunity for wide array of stakeholders to input, manage and monitor the required data anytime from anywhere. With this technology fully in-place, Katherinenquartier project team and ViCon has together taken BIM into a new sphere of project management.
