Andrew Dunlap’s primary work experience is in the analysis and development of exterior building enclosures, including historic buildings. Exterior enclosure expertise is comprised of roofing, skylights, windows, curtain walls, rainscreen/cavity walls and waterproofing, and includes development of remediation options and construction documents for corrective work. Andrew’s work focuses on providing energy efficient designs as he regularly participates in validating designs for energy code compliance or to exceed code requirements. Project responsibilities include the collection of detailed building information, investigation and analysis of existing conditions, computerized thermal analysis of building systems (WUFI 5.2, THERM 7, WINDOW 7, and other software packages), formulation of remediation plans, preparation of construction documents for remediation, and construction contract administration including field observation and systems testing. This work often includes performing diagnostic field water tests as part of the forensic investigations or used to validate installed conditions.

Sarah Flock has over 12 years of architectural experience in water/moisture intrusion investigations, repair design, and field testing of distressed structures, and nonperforming buildings and material systems. At RRJ, she has specialized in building enclosure assessment and in the resolution of moisture intrusion, including condensation formation. She has performed hygrothermal modeling to analyze a wide range of projects utilizing her knowledge and expertise in THERM, WUFI, and other types of computer analyses. Building materials and systems she has evaluated and tested include masonry, windows, curtain walls, metal panels, stucco, wood and vinyl cladding systems, and exterior insulation and finish systems (EIFS). Her experience has involved architectural peer review of building enclosures and assemblies to ensure the designs meet the demanding codes and standards for energy efficiency and environmental performance. With her extensive building enclosure knowledge, she has provided litigation support and served as an expert witness on a variety of related failures. Previously, she gained experience working at both an engineering firm and residential design practice in the areas of site investigations, code analysis, construction documents, and interactive graphics.

She served as a teaching assistant for a construction and building technology course while working on her Master’s degree at the University of Illinois, Urbana-Champaign.
