Past Technical Workshops

Keeping the northwest region embraced in preservation and technology for our built heritage. The APTNW Chapter hosts a technical workshop focusing on a variety of material topics each spring. Our venue cities change to accommodate our local members of our region. Technical workshops are day long and comprised of a line up of experienced local speakers and ends with a walking tour. These are an excellent way to gain more knowledge in the field of preservation technology and network with other professionals of our region.
