AECC3 – Entrepreneurship in the AEC Community – KP Reddy and Chuck Eastman

The Workshop on AEC Entrepreneurship on the Cloud recognizes this time as an historical moment bringing together cloud computing, hand held graphic devices, Building Information Modeling  that is leading to revolutionary transitions in building that will forever change AECO practices. The workshop  was held on October 14 and 15, 2013. It focused on the entrepreneurial development of new innovative and advanced technologies that will lead the design, engineering and construction industry into the future. There were about 35 attendees. Bringing together entrepreneurs and capital raising leaders with people with ideas and vision, the workshop was meant to set the stage and provide opportunities to develop business partnerships and engaging investors.


Behavioral-centric systems integration in building models using SysML - Andres Cavieres and Francisco Valdes

The integration of BIM with System Modeling Language (SysML) is intended to support the collaborative modeling of a complex building project as a “system-of-systems”. SysML provides modeling capabilities not available in current BIM applications, including the ability to represent complex behavioral relationships such as the mechanical relationships between a structural steel frame and precast enclosures. Typical examples are last minute design changes to reduce costs that may have thermal, acoustical or other performance implications. Additionally, SysML supports the description of test cases for verification and validation of design alternatives. A case study towill illustrate the need for such systems-level perspective we propose the problem of tolerance specification for building components, specifically connections and interfaces between dissimilar construction systems. We propose the development of a prototype implementation to demonstrate this functionality, by integrating SysML with a parametric modeling application.  


Model Query Solution for Quantity Takeoff and Cost Estimation-  Shiva Aram

My assessment of major available tools for quantity takeoff and cost estimation as well as interviews with some of the top US general contractors and subcontractors revealed the following shortcomings in their cost estimation process:

  • quantity takeoff tools don’t extract much of design features’ information critical for accurate cost estimation

  • cost estimation process for many subcontractors is mainly manual.
  • Mapping quantity takeoff items to cost items/assemblies is manual.

This research project includes three major stages:

  • Conduct research on supply chain and current employed cost estimation process by GCs and subcontractors; evaluate production and construction processes of selected domains in order to identify and analyze impacts of design features on project cost.
  • Devise a set of rules and workflows to rigorously analyze designed objects’ feature properties based on their impact on cost.
  • Provide a prototypical solution that through semantic queries analyzes object properties of building models and based on devised rules infer new knowledge critical for cost estimation and target value design. 

Such a solution will greatly assist project entities especially general contractors and subcontractors by extracting more intelligence from design


Toward a More Successful Implementation of BIM in the Design-Bid-Build (DBB) Setting: Analysis of Existing BIMImplementation Plan through a Case-Study Approach- Pardis Pishdad-Bozorgi

Alternative delivery processes, such as Design-Build (DB) and Integrated Project Delivery (IPD) approaches are known to provide a better platform for proper implementation of Building Information Modeling (BIM). However, BIM can successfully be implemented using any project delivery method. This proposal aims to look into the Design-Bid-Build delivery method to explore how BIM can be most efficiently implemented in this delivery process. Some organizations, such as Smithsonian Institution,ENG works, and Georgia Institute of Technology have recognized the need for BIM implementation plan and have recently developed BIM strategies in support of their EPC efforts. This proposal aims to closely study and analyze the implementation of these newly developed BIM Strategies in a Design-Bid-Build setting and to further advance them by identifying and addressing their implementation issues. Through case study approach, this research will study and analyze the benefits, challenges, and the gaps associated with these newly developed guidelines to support a seamless development/flow of digital information throughout a project life cycle.


Determining the Impact and Effectiveness of BIM – Baabak Ashuri and Saman YarMohammadi

The objective of this research was to determine the impact and effectiveness of Building information Modeling (BIM) – in its varied dimensions. The impact of BIM is quantified on various project variables, such as number of Requests for Information (RFIs) and Change Orders (COs), considering several project characteristics, maturity of BIM leadership on project, project complexity and scale, and other factors. Another goal is to improve the metrics for assessing BIM productivity.


Design and Construction Applications of BIM-Based Mobile Augmented Reality – Javier Irizarry

This research will study the implications of the use of the BIM-Based InfoSPOT prototype for architectural design and construction applications. With the cooperation of DBL members, the research team will use the InfoSPOT prototype in the performance of design and construction related tasks defined with the assistance of participating DBL members.  Real projects will be used in the proposed research and will be documented through a case study approach. The ultimate goal of the research is to evaluate the performance of Mobile Augmented Reality in the tasks defined.
