WS2—Preservation Engineering: Principles and Practice in the Assessment and Treatment of Heritage Structures-

SOLD OUT! Waiting list only.
Sponsored by the APT Preservation Engineering Technical Committee
8:00–4:30  Sunday and Monday, October 26 & 27


Description
Architects and engineers who are guided by a preservation philosophy are well served with management hierarchies that allow projects to move efficiently through evaluations, diagnosis, and remediation in the face of ethical and legal (codes) challenges.

A solid preservation philosophy for heritage structures necessitates the proper assessment of the structural adequacy of heritage buildings, in conjunction with a proper interpretation and application of relevant codes and regulations. This workshop will cover this in depth, as well as present methods to implement and design structural remediation.

Facilitators will begin with establishing a common language between architects, engineers, and professionals by presenting general issues related to structural preservation:
• philosophical approaches to intervening on historic structures;
• an overview of structural systems in traditional and contemporary buildings;
• an overview of structural upgrades in historic buildings; and
• the assessment of code requirements versus the performance of existing structures.

They will then prove the need for understanding the existing structural components, how to establish a systematic diagnostic approach and how to propose appropriate solutions.

As the workshop proceeds, discussions will concentrate on
• the therapy and long term monitoring of heritage structures;
• the merits of a comprehensive analysis of historic structures before intervention;
• examples of remediation, both successful and not so successful;
• various analytical tools and methods; and
• ramifications of introducing new materials and technologies in existing buildings.

The workshop will conclude with issues of tectonics and material compatibility, tying the discussion into the overall Conference theme.

Field visits and case studies will provide opportunities for hands-on practice, to discuss the material presented, and interact with the facilitators.

Learning Objectives
Through a series of presentations and field visits outlining the challenges and opportunities regarding the treatment of heritage structures, workshop attendees should be able to:
1. Discuss the philosophies and strategies regarding engineering for heritage structures in traditional, hybrid and contemporary buildings;
2. Differentiate between performance-based design and code-based design requirements considering the context of legal necessities in dealing with codes in a balanced approach with engineering judgment;
3. Discuss structural diagnostics related to effects on components by receiving a general overview of diagnostic tools for assessing heritage structures and assessing existing structural capacities;
4. Present therapy and long-term monitoring methodologies of heritage structures based on discussions of analysis as tool, creating models, and running simulations to draw conclusions to better understand differential stresses between the structural frames, walls/claddings and interior finishes as remediation approaches are identified;
5. Discuss material compatibility concerns and related implications when using new materials for the remediation and treatment of heritage structures;
6. Provide examples illustrating a focused review of remediation approaches for heritage structures and carry on a detailed discussion regarding materials assessment.
