75458 - Materials and Technologies for Historic Buildings M

Learning outcomes

At the end of the class, student has knowledge of the evolution of both the historic materials and construction techniques and the repair methods, especially focusing on stone, wood and masonry. In particular, at the end of the course he/she is able to specify a set of criteria useful to ensure that the materials selected for conservation and rehabilitation are best suited to the needs of each building in terms of safety, efficiency, compatibility and cost effectiveness, as a palette of variables that the design must manage simultaneously.

Course contents

1. Introduction: rehabilitation, repair and maintenance processes for historic buildings. Performance-based building design for historic buildings.

2. Historic Construction Materials and Techniques.

a. Timber structures: wood properties, structural timber.

b. Stone and brick masonry: stone masonry, brick masonry, masonry mortar.

c. Construction technologies and structural elements: foundations, walls, piers and columns, beams, floors, roofs and trusses, arches and vaults.

3. Building pathology.

a. Building pathology definition. Defect, failure and anomaly.

b. Causes of decay in materials and structure. Investigation process. Diagnostic process. Diagnostic system for non-destructive surveys of building constructions.

c. Cases of failures. Defects information sheets. Review of failures and defects.

4. Repair techniques:

a. Stone and bricks masonry retrofitting.

b. Structural timber repairs.

c. Rehabilitation project building site: temporary works, scaffolding, drilling works, grouting.

5. Facility Management & cost control

a. Maintenance process of historic buildings.

b. Cost control of rehabilitation projects.

c. Life Cycle Cost Analysis (LCC).

Teaching methods

The course content will be entirely covered by lectures.

Mandatory homework / project work will deepen course topics, students can have support from the computer laboratory of the faculty. In-class practical works will be evaluated in the final exam. Attendance in practical classes is recommended.

Assessment methods

Achievements will be assessed by the means of a final exam. This is based on an analytical assessment of the "expected learning outcomes" described above.

In order to properly assess such achievement the examination is composed of different sessions: written session, which consist of a test composed of questions; to be eligible to take the oral exam the student must score in the written test a minimum total of 18 points with a maximum of 30.

The oral session, consists of: a review of the homework and of the in-class exercises, and a review of the written output, in which examiners inform the student on grading criteria, and receive any student appeal supported by appropriate explanations; and a technical conversation.

In the final exam written and oral examinations are mandatory. Homework and in-class exercises will be evaluated and discussed in final exam. Homework must be completed and passed prior the oral exam.

Higher grades will be awarded to students who demonstrate an organic understanding of the subject, a high ability for critical application, and a clear and concise presentation of the contents.

To obtain a passing grade, students are required to at least demonstrate a knowledge of the key concepts of the subject, some ability for critical application, and a comprehensible use of technical language.

A failing grade will be awarded if the student shows knowledge gaps in key-concepts of the subject, inappropriate use of language, and/or logic failures in the analysis of the subject.

Teaching tools

The teaching tools are projector and PC.
