8:00 - 8:45 am               Breakfast and Registration

8:45 - 9:15 am               Welcome & Opening Remarks
James W. Shepherd, AIA, LEED AP, Washington National Cathedral 

9:15 - 10:00 am             Measuring Complicated Buildings – An Overview, History and Current Situation
This presentation will discuss the history of measuring and documenting buildings – how technologies and the interpretation of data have evolved. The presenter also will touch on future research and development needs including data integration.
Chris Gray, FRICS, Mollenhauer Group, Los Angeles, CA

10:00 – 10:15 am          Break

10:15 - 11:00 am           Architect's Digital Documentation Toolbox
Application of the traditional project management triangle (time-cost-quality) as it relates to the selection and implementation of various technologies will be discussed. The presenter will review the use of technologies at various phases of a project, as well as the use of multiple technologies together and their integration and degree of implementation. The application of technologies at different scales of projects also will be examined, using micro/macro comparisons – of both project size and level of detail required.
Purvi Gandhi Irwin, AIA LEED AP BD+C, CADD Microsystems

11:00 am – 11:45 am  Client Perspective:  Scanning the Washington National Cathedral
The 2011 5.8 magnitude earthquake on the east coast caused over $34 million in damage to Washington National Cathedral in Washington DC.  A first step to plan recovery and repairs was acquiring very accurate documentation of the historic building that had previously not existed.  This session will provide a critical review, from the client perspective, of commissioning a laser scan survey. Lessons learned will be shared as well as recommendations for what questions to ask when seeking out consultants to provide such documentation services.
James W. Shepherd, AIA, LEED AP, Washington National Cathedral

11:45 - 12:00 pm          Questions/Answers

12:00 - 1:30 pm            Lunch on your own – EXPLORE THE HISTORIC NEIGHBORHOOD ESTABLISHMENTS!

1:30 - 2:15 pm               Comparative Analysis of Remote-Sensor Survey Tools   
This session will provide a comparative analysis of the variety of tools available for the measurement, survey and recording of historic resources, from individual buildings to historic districts.  It will include a technical review and comparison of photogrammetry and laser scanning equipment and techniques.
John M. Evans, AIA, LEED AP, Preservation Design Partnership, LLC

2:15 - 3:00 pm              Non-Destructive Evaluation (NDE)
Documentation efforts typically concentrate on evaluating visible external features and resort to destructive probe openings for identifying localized concealed conditions. As an alternative to probe openings, nondestructive evaluation (NDE) techniques are used to evaluate subsurface hidden conditions without damage to historic materials. Several common evaluation approaches will be discussed, including surface hardness measurements, metal detection, pulse velocity methods, microwave radar, and infrared thermography. Borescope and videoscope methods will also be presented and, while not truly nondestructive, these techniques enable visual observations via small-diameter holes drilled in mortar joints. This workshop topic will include advice on setting up an evaluation program and calibration approaches to ensure NDE methods provide useful data.
Julie Maddox, PE, Atkinson-Noland &Associates

3:00 - 3:15 pm              Break

3:15 - 4:00 pm              Hygrothermal and Energy Documentation Concepts
Building physics background, benefits, and limitations for implementing hygrothermal documentation, modeling and analysis to existing buildings will be covered. Usage of whole building air leakage equipment, infrared thermography, and window air leakage testing in a holistic energy performance evaluation of existing buildings will be discussed.
Marcus Eliason, PE, Apollo BBC

4:00 - 4:45 pm             Special Cases in Documentation: Drones and UAVs
Exciting and rapidly-evolving developments in the world of unmanned aerial vehicles (UAVs) allow inspection teams to quickly and safely gather critical data from challenging locations on building and structures. With the combination of high-resolution imaging and photogrammetry tools, live-feed video streams, infrared thermography, and UAVs, a wide range of new documentation opportunities are now available. This final session will review the latest technical and regulatory advances in the use of UAVs in the practice of architectural documentation and will include illustrated examples of the types of documentation created using UAVs.
Annabelle Radcliffe-Trenner, AIA, RIBA, LEED AP, Historic Building Architects, LLC and Kristen Olson / Joe Haun, Vertical Access

4:45 - 5:00 pm             Questions/Answers

5:00 - 5:45 pm            Round Table Review: Discussion of Lessons Learned
Workshop attendees are encouraged to engage in a discussion of current projects, lessons learned from current and past projects, challenges with documentation technologies, and other pertinent topics.

6:00 - 8:00 pm            RECEPTION
Join presenters and fellow workshop attendees for some light refreshments and libations! Networking and continued intellectual discussions highly encouraged!
