CURRICULUM VITAE
____________________________________________________________________________________________________________________________________________________
About me:
Most recently I have had the pleasure to work with Hensel Phelps as the BIM/VDC Manager for the Southern California district. During this time I worked on the winning proposals for the United Airlines Terminal modernization at LAX, and student housing projects at UC Irvine and UC San Diego. I also provided BIM support to our teams at Kaiser Hospital San Diego, Terminal 1 (Southwest) and Terminal 2 (Westfield Malls) at LAX, and our numerous other projects in SoCal. I also worked closely with my counterparts at the corporate office and other districts on the development and implementation of BIM/VDC standards.

Prior to my work with HP I was a consultant in the San Francisco Bay Area for general contractors, including Clark and McCarthy, as well as a variety of architects, subcontractors, and equipment vendors. During this time I worked on numerous proposals including the new Apple office complex (the "spaceship"), the VMware campus, and numerous others. I also provided BIM management, production, and coordination services for a wide range of projects including laboratories, hospitals, and even an amusement park, among many others.

I have also worked with View by View on large hospital, education, and other projects providing BIM modeling, coordination and support services. View by View is widely recognized as a pioneer in BIM beginning with their groundbreaking work on the Letterman Arts Center for George Lukas among many other accomplishments. It has been an invaluable experience to work with such leaders in the world of BIM.

In addition to my experience in BIM modeling and coordination, I have worked with many firms to develop, implement, document and maintain BIM and CAD standards and practices. My clients have included Architects, Engineers, Contractors, Owner/Developers and Government Agencies.

Prior to focusing my efforts on the development and implementation of BIM and CAD standards and practices I worked as a general contractor and before that as a master carpenter and cabinet maker. These early experiences have served to provide me with both the experience of how buildings are built and an understanding of the importance of attention to detail, getting things right the first time and fixing them quickly when necessary.

I look forward to continuing to explore ways that BIM practices can facilitate team building and communications to improve the design, engineering, construction and maintenance of the built environment.

Skills:
BIM Consulting & Coordination
I have worked with Architects, Engineers, Contractors, building owners, governmental agencies and software developers to establish, develop, use and maintain BIM practices and standards. The primary focus of my career is the implementation, customization and documentation of BIM standards and practices. I have developed standards over twenty firms and agencies directly and influenced developments in many more indirectly through my lectures and network of associates. In addition to my own resources, skills and experience I have access to a wide range of connections and associations that I can draw upon in the worldwide community of BIM users and developers.
Teamwork & Management
Working in a broad range of projects with widely differing firms and disciplines has afforded me considerable experience with large and small teams of all sorts. I have worked at all levels of management and responsibility in architectural design, construction management and BIM deployment. I understand what it takes to get things done and will fulfill whatever role is required to make that happen.

Construction Management
I have experience as the primary general contractor or construction manager on projects ranging up to several million in construction costs. I have also worked in collaboration with others on projects into the hundreds of millions, including hospitals, commercial and residential development projects. This experience dovetails with my experience in BIM modeling to provide an exceptional skill set for construction coordination.
File Formats & Translation
Working with and having to coordinate a wide range of BIM, CAD and other software has provided me the opportunity to learn the ins and outs of translating files and interoperating successfully for BIM coordination and construction management.

Revit, NavisWorks, ArchiCAD, Solibri, Tekla and a host of other programs can be made to successfully interoperate with IFC, DWG, 3DS, DWF, NWC and other formats. While this process is still time consuming and requires careful setup it can be made quite reliable and reasonably efficient. In time this will inevitably become more automatic and robust as we build on the lessons learned.
Design Collaboration
My experience with a wide range of Architects, Planners and Designers has given me an understanding of the methods, processes and issues involved in the creation and execution of schematic design, design development and construction documentation. The combination of architectural and construction experience makes me particularly qualified in architectural detailing, problem solving and matters of constructibility.
Computer Programming
Since customization often provides major benefits in the use of BIM software I have become experienced in scripting and high level programming languages in order to create specialized libraries and adapt the programs to the particular needs of my clients. I have also worked on libraries for the localization of BIM software to specific national practices in the US, Canada and Croatia. In 1996 I was responsible for the development of the US content library of doors, windows and other parts for the localization of the german BIM program speedikon (by IEZ) for the US market.
