Along with the technical designs, they show the building control officers what you are planning to do, and help them assess whether your plans are in line with current building regulations. 2) Beams Self Weight per running meter. The loads you calculate will probably be 15-20% higher than the actual load at design conditions, which gives you a buffer to help meet the extreme loads. The vast difference in cost of both the types of building is not only because of the regulatory licences and code practices adhered to,and the cost of materials used but also because of the overhead. Wind pressure is the overall force applied upon a structure by wind. They include the self-weight of structural members, such as walls, plasters, ceilings, floors, beams, columns, and roofs. In terms of the actual load on a structure, there is no difference between dead or live loading, but the split occurs for use in safety calculations or ease of analysis on complex models.
