Glossary of common terms

Access panel (cover)

                        

An opening in flooring or ceiling or other part of a structure (such as service hatch, removable panel) to allow for entry to carry out an inspection, maintenance or repair. 

                            

Accessible area

Accreditation

Accreditation is the procedure by which an authorised independent body gives formal recognition that a conformity assessment entity is competent and proficient to carry out calibrations, tests, inspections and/or certifications.

Antiquated


No longer in use, useful or functioning, as in most home inspection associations. Obsolete.

                        

Appearance defect

                        

Fault or deviation from the intended appearance of a building element.

Architect

While virtually anyone can draw up plans and call themselves a “building designer”, only a person registered by the Architects Board of WA can use the title “architect”. But the distinction is far more substantial than the just the title used.

Architects must have gained approved tertiary qualifications (or equivalent), have undertaken a two-year period of practical experience and have successfully completed both the written and oral parts of the Architectural Practice Examination before becoming eligible to apply for registration, and qualifying to use the title “architect”.

 

Areaway


An open subsurface space adjacent to a building used to admit light/air or as a means of access to a basement.                        

Building element

                        

Portion of a building that, by itself or in combination with other such parts, fulfils a characteristic function.

                        

NOTE: For example supporting, enclosing, furnishing or servicing building space.

Associated waterproofing elements

Building Surveyor

In Australia, a Building Surveyor is a professional who is tasked with understanding the building control process. A Building Surveyor has the authority to assess building plans to ensure that they comply with the Building Code of Australia, the Australian Standards referenced within it and any other relevant Building Acts or other legislation or requirements of the jurisdiction the building is in. Building Surveyors are either private or municipal.

Exterior elevated element 

 

Means the following types of structures, including their supports and railings: balconies, decks, porches, stairways, walkways, and entry structures that extend beyond exterior walls of the building and which have a walking surface that is elevated more than six feet above ground level, are designed for human occupancy or use, and rely in whole or in substantial part on wood or wood-based products for structural support or stability of the exterior elevated element.

Modularisation (Modularization) 

Modular design is an engineering technique that a design of complete unit or plant divide into smaller units (system or subsystem) with tie-in provisions. Modularisation (or Modularization) is for difficulties in a skilled labour mobilisation at the site or remote areas and significantly disadvantages in economics for a traditional stick built construction method, requires large number of labour, construction equipment and supporting infrastructures, modularisation method is applicable. Modules are self contained and operated with essential utility supply. Module design and Engineering is slightly different form a normal engineering, reinforcement of structures for transportations and minimize ground spaces are executed, modules are fabricated (pre-fabricated) or manufactured at the module shop yard, tested, pre-commissioned, preserved and transported to the site for installation and connection (tie-ins) to other module or existing facility to complete a unit or plant. Modularisation plan develops in the beginning of the project, and perform a module design and engineering, procurement and construction. Optimum Module Size and Inclusions are depend on a transportation ability for inland and ocean, module erection and handling capacity at the site, module fabrication yard capacity as well as ability of skilled labour mobilisation and level of direct cost at the site, and a severity of project such as project duration, quality, safety and environmental requirement.
In general, a Modularisation project is shorter project schedule, but cost is dependent.
