The new Code has addressed this problem by requiring alarm signals to have a standardized sound pattern, conforming to a referenced standard. This is to ensure that an alarm can be properly heard and understood, thereby expediting evacuation, and reducing injuries and loss of life. Other important Code changes Some of the other improvements to the Code that may be of interest include the move, in Part 4, Structural Design , to Limit States Design for foundations. Limit States Design permits greater design flexibility and has the potential to offer economic benefits. All sections that relate only to houses have been shifted to Part 9, Housing and Small Buildings, allowing the house to be dealt with as a complete system.
Greater choice can help reduce costs and achieve better building performance.
