Text Mining of BIM Model Log Files to Extract Useful Information for Enhancing Design Process - Babaak Ashuri (Building Construction) 
Log files record the actions taken by aa BIM user during multiple session of BIM projects. They contain tremendous amount of information, but very few practitioners or researchers have good ideas about how to make good use of the information embedded in BIM log files. The proposed project is aimed at discovering what information log files contain and how one can extract and further analyze the information to improve the design process. The information can be utilized to measure production rate (i.e., productivity) at the project level, the performance of each team member involved in the BIM model development, keep track of the design progress of each element in the BIM model, and find the most common design issues of BIM projects. DBL members are expected to benefit from the outcome of this research through (a) better understanding of embedded information in BIM model log files; and (b) developing customized text mining techniques to retrieve interesting insights related to major productivity issues that should be overcome to enhance the quality of design process.

Data model and processes for building programming - John Haymaker and Chuck Eastman (Architecture) 
Current building programming definition and management processes are sequential, ad hoc, and error-prone because they are not based on a formal model and process. This research project proposes to develop a data model, interfaces, and processes to support the creation, application, verification, and modification of building program data. We will create system maps of the current and desired programming processes with two DBL member companies. We will evaluate current and emerging technologies. Through a, multidisciplinary, semester-long student classroom project, we will prototype a future state process and test it on DBL member project data.  Contributions include the resulting model and process described in SysML, an open-source implementation in Dynamo, and validation on industry projects.

Digital Mockups - Daniel Baerlacken (Architecture)
Mock-ups are generated for most large façade projects; they are expensive, difficult to change but have many virtues: (1) Subs can try out assembly sequences and refine them if needed; they may be complex; (2) In some cases, engineering tests for water and air leakage/deflection can be applied; (3) Provides a visual example how façade and details will appear, allowing limited trade-offs. Can using various software tools virtualize the benefits of mock-ups? Can a facade assembly be put together in a virtual environment and tested for mechanical assembly? How might alternative detailing be tested? How can using these tools increase the validity of performance testing?

BIM-integrated Wireless Localization Technology for Construction Management and Communication - Yong K. Cho (Civil & Environmental Engineering)
Construction becomes larger, more dynamic and complex, and demands better organized and effective management skills and tools. Many problems and issues related to defects, safety hazards, productivity at construction sites are location-based. This research aims to identify and develop a low-cost new technology that enables real-time location tracking of mobile users (e.g., superintendent, inspector) for more efficient construction project management within a 2D/3D BIM  environments utilizing mobile devices over Bluetooth and wireless mobile data networks. Utilizing highly sophisticated wireless localization technology with BIM, the quality of construction management and communication can be significantly enhanced via seamless communication among all stakeholders in a timely manner.
