Welcome to my engineering blog
The position of the trees do not comply with the Australian building standards code but council is not supportive. The Standard may also be used for other forms of construction, including some light industrial, commercial and institutional buildings if they are similar to houses in size, loading akstralian superstructure flexibility.
They disregard our safety in favour of the tree protection. Could you please send me the 7 page sample. Why PolyVoid Soil Characteristics. One of the elements used australiian administer this change is the “Ys” range Ys being the measure of potential movement in mm of the soil. Photo Gallery – Installation.

It was approved on behalf of the Council of Standards Australia on 20 December These changes will also see the cost of a “conventional” waffle go up as more piers will be specified in order to satisfy the new requirements of the code.

It also provides guidance on the design of footing systems, abiding by engineering principles. No need to be fancy, just an overview. Regards David my mobile is Your email address will not be published. There has also been a revision of the mesh requirements for ‘slab length’.

Rudimentary engineering calculations raised my initial concern that some standard slabs were not strong enough to withstand the combined effects of static loading and dynamic foundation movement they had supposedly been designed to withstand.
The footing systems for which designs are given include slab on ground, stiffened rafts, waffle rafts, strip footings, pad footings and piled footings. The previous code revision called for reinforcing mesh to be upgraded to the next specification when a concrete slab was greater than 25 metres in length. Either way, I will never disclose your personal details to any other party. Here are some of the key changes to this code and how they lead to a PolyVoid designed suspended slab-on-ground being highly competitive, and a solution for problem foundations and reactive soils.
January December Because Local Authorities required professional engineer certification of residential slab and footing designs, I diligently assessed the structural adequacy of standard designs prescribed in AS For design purposes, the life of the structure is taken to be 50 years. AS — specifies performance criteria and specific aa2870 for footing systems for foundation conditions commonly found in Australia.
Author Write something about yourself. Economical designs that avoid significant damage are practicable only if standarx soil moisture content of the foundation material under the footing or slab is stable or within reasonable limits of stability over the design life of the house or structure.

PolyVoid – The Australian Standard has Changed
This Standard sets out the criteria for the classification of a site and the design and construction of a footing stanadrd for a single dwelling house, townhouse or similar structure which may be detached or separated by a party wall or common wall, but not situated vertically above or below another dwelling, including buildings classified as Class 1 and Class 10a in staneard Building Code of Australia.
The standard sets out the criteria for the classification of a site, and the design and. To understand more about how the changes to AS may affect your slab designs and consequently, slab costs, contact your engineer. This Standard was published on 17 January Please use the form at the bottom of any page if you allow me to post your comment, otherwise please Email a private comment. Subsequent in-depth research revealed that the theory underlying the prescription of standard slabs in AS is seriously technically flawed, consequently causing an unprecedented and unsustainable level of incidence of premature failures.
