1.3  Terms and definitions
For the purpose of this document, the following terms and definitions apply. 1.3.1 backfill free-draining material or nominated blends of sand and cement 1.3.2 bedding sand or similar free draining material 1.3.3 bond beam structural member that supports the coping 1.3.4 competent person person who has acquired, through education, training, qualification or experience or a combination of these, the knowledge and skill enabling that person to perform the task required Note 1 to entry: An example would be a professional engineer who is — (i) a corporate member of the Institution of Engineers Australia; (ii) eligible to become a corporate member of the Institution of Engineers, Australia, and has appropriate experience and competence in the relevant field; (iii) a Chartered Professional Engineer (CPEng) or equivalent qualifications recognized by Engineers Australia with experience in a relevant area of practice; or (iv) a person who is eligible for the grade of Member (MIEAust) of Engineers Australia with experience in the relevant area of practice.1.3.5 coping horizontal rim or pool edge which is moulded integrally with the pool shell 1.3.6 hydrodynamic pressure pressure created by moving water leading to impact on a pool installation Note 1 to entry: May be caused by storms, burst pipes or any circumstances of differential water pressure leading to a flow of water. 1.3.7 hydrostatic pressure pressure created by a change in the level of the water table 1.3.8 hydrostatic relief valve means to reduce water pressure around the outside of a pool 1.3.9 installation tolerance combination of manufacturing tolerance, design deflection and installation deviation 1.3.10 may indicates the existence of an option 1.3.11 naturally cementitious material silty sand which “goes hard” when exposed to sunlight 1.3.12 pump and sump system method for removing excess water around a pool using a pump connected to a low-lying drainage sump 1.3.13 reactive clay clay soil which swells or shrinks with changing moisture content 1.3.14 relevant authority agency authorized by legislation or regulation to issue determinations, orders, or other instructions in respect of any subject covered by this document 1.3.15 shall indicates that a statement is mandatory 1.3.16 should indicates a recommendation 1.3.17 seasonal movement movement which can occur due to seasonal moisture change in reactive clay 1.3.18 step ledge internal ledge in a pool
3.1  General Installation of the pool shall be in accordance with the design specification for use of the pool shell and installation requirements for the site, taking into account — (a) loading from hydrostatic pressure; (b) hydrodynamic pressure; (c) reactive clay; and (d) any additional loadings that do not form an integral part of the design criteria of the pool shell. 3.2  Condition of the pool at the point of delivery Prior to installation, an inspection of the pool shell shall be carried out to ensure that it is free from visual defects and fit for purpose. Moulding and blow-off marks shall not be determined as defects. 3.3  Site investigation A site investigation shall be undertaken prior to commencement of work to ensure that the proposed installation of the pool shell is suitable for the conditions of the site as specified in Clause 3.1. 3.4  Hydrostatic pressure Hydrostatic pressure on the pool shall be controlled in the installation. NOTE  Hydrostatic pressure control is to prevent the possibility of flotation or upward displacement of the pool floor and deflection of the pool walls, see Clause 6.2 for drainage requirements. 3.5  Hydrodynamic pressure Damaging effects of hydrodynamic pressure caused by moving sub-surface water shall be minimised in the installation. NOTE  These effects may include erosion of backfill or bedding, and may impose additional loads on the pool, see Clause 6.2 for drainage requirements.
