The School of Engineering at the University of Vermont (UVM) has been exploring the addition of heritage preservation engineering modules to its existing curriculum. NCPTT and the Getty Conservation Institute hosted a colloquium in June 2009 to identify curricular additions for a program focused on the engineering evaluation and remediation of heritage structures. The colloquium focused on the quantitative techniques and methodologies applied to the engineering evaluation and remediation of heritage structures, and the challenge of ensuring that students acquire the competencies necessary to address the challenges of the market.
