Course Overview:
 Course focuses on issues related to failures in buildings, decay and damage, approaches for maintenance, repairs and renovation of buildings.

Objectives of the Course:
 To create awareness among the students regarding problems related to old buildings and methods to mitigate their problems.

Course Contents:

 Unit - I Failures:
 Introduction to building failures: causes of decay and damage in old buildings, issues of maintenance and repair. Preliminary inspection and general observation, decayed elements difference between decay and damage.

Unit - II Timber:
Moisture content, treatment prior to installation, factors reducing strength of timber, approach to repair and to the timber roofing system.

Unit - III Bricks:
Strength reducing factors in brick work, effect of ageing, weathering, temperature variation of brick-work, joints and cracks, construction defects, repair and maintenance.

Unit - IV
R.C. Concrete: Mixing methods at site, structural design for repairs, causes of failure in concrete structures, pressure-grouting.

Unit - V
 Methodical approach to Repairs: Cracks over openings, sinking and sagging balconies, repairs to decayed floors and floor joints, example: Jack arch., madras roof terrace, foundation sinking, repairs to walls. Propping, strutting and under pinning.

Unit - VI 
Unusual problems: Repairs to large span rooms, water proofing the roof terraces, leakages from toilets, case studies and site visits.

Factors influencing architecture and vernacular architecture    Factors that affect architectural design   Each project has a different set of requirements, limitations, challenges, and opportunities that affect a project’s cultural, environmental, technological, and aesthetic contexts. The 10 factors presented below are among the most influential.  CLIENT Some clients have a clear idea of a program, budget, and other project objectives, including the final appearance of the building. Others look to their architect to help them define the project objectives and to design a building that meets those objectives. In both cases the effectiveness of the relationship between client and architect is a major factor in making and implementing design decisions throughout the project. PROGRAM All clients have a series of aspirations, requirements, and limitations to be met in design. The program provides a place for identifying and delineating these factors and any number of r

UNIT V---METHODICAL APPROACH TO REPAIRS   CRACKS OVER OPENINGS :  The cracks over the windows had developed over many years due to rusting lintels.   Lintels are made of steel and support the brick over a window openings.     Rusting lintels are the number one reason cracks occur above window frames.    This generally is not a structural issue, but can develop into a structural issue if left unrepaired.  REPAIR :    The only true way to tell if a crack is active is to install a crack monitor.    The proper way to install a crack monitor is to epoxy the monitor to both sides of the crack and leave on the wall or foundation for as long as possible.    SINKING BALCONIES :   There are many things that can increase the risk of injury on a property.    Loose railings on decks and walkways are one of the areas that we need to be aware of.   Wood railing, iron railings, stucco, or even concrete have to be checked regularly to be safe.   The bolt holding the iro
