As historic preservation and adaptive re-use of existing buildings feature ever-more strongly in the mainstream of architectural practice, methods to clean masonry facades in a benign and cost effective manner need to be better understood as part of the PRMAI (preservation, repair, maintenance and improvements) skill sets of those concerned with condition assessments, design and specification work. Many famous buildings have been butchered by well-meaning but inappropriate cleaning techniques. The expert speaker will guide attendees through the many pitfalls towards best practice in this complicated field.


Objective 1: The types of pollution / surface deposition causing increased soiling on building facades 
Objective 2: The limitations and advantages of cleaning systems related to the physio-chemical sensitivities of different masonry surfaces and substrates to cleaning systems
Objective 3: Health, safety and environmental implications of façade cleaning practices
Objective 4: How ASTM and other standards are limited and need careful usage
Objective 5: How best practice in the design and specification of façade masonry cleaning can translate to benign and cost effective results

Based in Los Angeles and running an international technical consultancy business serving the AEC industry, John Fidler is a British-licensed architect with two postgraduate degrees in building conservation and over 35 years of specialist experience concerned with the cleaning and repair of buildings. He was formerly the Conservation Director of English Heritage responsible for the care of over 420 properties of national importance including the World Heritage Sites of Stonehenge and Hadrian’ Wall. He was chairman and co-author of British Standard 8221/2: 2000, The Cleaning and Surface Repair of Buildings and teaches on the International Stone Conservation course run by the Getty Conservation Institute and ICCROM in Rome.

We will have a “Historic Happy Hour” at Casey’s Irish Pub immediately following the lecture.

Built as a two-story structure in 1916, the original building housed a Turkish Bath below a General Store. The building did not begin its life as an eatery until 1924 when it was converted into the B&M Cafeteria, a place for the elite. Six years later it was renovated into a Spanish style restaurant, La Palma. Even when investment banking took downtown in the early ‘60s the building managed to avoid replacement and maintain its culinary connection as a private dinner club with Sumitoma Bank occupying the ground floor.

In 1969 the Casey’s we now know and love was created by moving the façade 30-feet back from the street to create the sunken patio.
