Summary of Content

The aim of this module is to gain knowledge and understanding of various types of problems in buildings and to identify repair/ maintenance techniques to be adopted.

Syllabus

The teaching syllabus will cover the following areas: Maintenance, repair and rehabilitation: Facets of Maintenance, importance of Maintenance, various aspects of Inspection, Assessment procedure for evaluating a damaged structure,, causes of deterioration, Definitions, development of maintenance policies and strategies/ models. Repair techniques and Refurbishment / upgrading concepts. Survey procedures- techniques(remote monitoring) and report writing, models, equipment, impulse radar, endoscopy, thermal imaging cameras, moisture meters, and other non-destructive techniques Cracks: Recording, monitoring, analysis and repair including grouting, reinforcing, reticulated stitching and corseting, underpinning including shoring, traditional proprietary systems including stooling, micro piles, pile based systems, and geotechnical solutions underpinning framed buildings, monitoring procedures during underpinning. Dampness: Rising, penetrating and condensation, consequences, diagnosis, monitoring and repair. Deterioration and repair of significant construction materials, timber, fungal and insect attack, repair techniques, both traditional and environmental, resin bonded repairs. Concrete: Quality assurance for concrete construction concrete properties- strength, permeability, thermal properties and cracking. - Effects due to climate, temperature, chemicals, corrosion - design and construction errors - Effects of cover thickness and cracking, Carbonation, sulphate attack, alkali silica reaction, Traditional and electrochemical protection and repair techniques, carbon and steel plate bonding, increasing load bearing capability of concrete structures by inserting new steel work, post tensioning etc. Rust eliminators and polymers coating for rebars during repair, foamed concrete, mortar and dry pack, vacuum concrete, Gunite and Shotcrete, Epoxy injection, Mortar repair for cracks, shoring and underpinning. Methods of corrosion protection, corrosion inhibitors, corrosion resistant steels, coatings and cathodic protection. Engineered demolition techniques for dilapidated structures - case studies. Masonry: Sulphate attack, deterioration of wall ties, stone deterioration, crystalline damage, chemical damage and contour scaling. Roofs: Pitched and flat roof defects, causes, investigation and repair. Catastrophic damage: Assessment and repair of fire, natural calamity and flood damaged buildings.

Learning Outcomes

On completion of this module the student should be able to:1. Identify the requirements to identify the cracks, its nature and diagnostic methods. A1,A5, A62. Compare alternative solutions to rectify or repair. B4,B5,C1C2,C3,C43. Demonstrate understanding of the interaction between the building fabric and refurbishment D1,D5

Teaching / Learning Strategy

Lectures will concentrate on principles and students will be expected to undertake significant private study and group discussions based on some case studies. Project work will be a mix of individual work and presentations.
