The rule is covered by various standard texts in the field of civil engineering, for instance Principles of Foundation Engineering by B.M. Das. The application of this rule is limited to foundations that are square or rectangular in plan. (For circular foundations a different rule, known as the Middle Quarter Rule applies). == References == - [[Professional Practice/Codes & Standards/National Building Code of India/Part 03 - Development Control Rules]] - [[History and Theory/World History/Medieval Architecture]] - [[Design/Building Typologies/Residential Architecture]] - [[Design/Building Typologies/Healthcare Architecture]] - [[Professional Practice/Ethics and Professional Conduct]] - [[Building Construction/Construction & Materials/Building Material/Natural Stone]] - [[Professional Practice/Codes & Standards/National Building Code of India/Part 06 - Structural Design/Section 5A - Plain and Reinforced Concrete]] - [[Professional Practice/Codes & Standards/Standards Index]] - [[Professional Practice/Codes & Standards/National Building Code of India/Part 07 - Construction Management]] - [[Wiki-Architecture/Architectural Concepts and History]]
