What is Verification of Evidence?

Written by Simon Keown on November 28th, 2007.      0 comments

Verification is the process of confirming a candidate’s ability to consistently meet the evidence requirements of the task as set down by the industry association and/or the New Zealand qualifications Authority (NZQA). A verifier’s role is to therefore provide proof that a student constantly meets the evidence requirements. This proof will provide additional information that will be used to decide whether the student meets the required level of competency for the particular Unit Standard.

Techniques for the Assessment of Competence

Written by Simon Keown on November 28th, 2007.      0 comments

There are two accepted forms of assessment, assessing practical performance (skills) and assessing theory (knowledge). For the assessment of skills the assessment can be on-job in an actual work situation or in a simulated environment. For the assessment of knowledge the assessment may be written or oral

Qualification Level Descriptions

Written by Simon Keown on November 28th, 2007.      0 comments

National Qualification Framework Level Descriptors The level descriptor matrix explains the level, processes, learning demand and application of standards registered on the National Qualifications Framework (NQF). The descriptor is a guide to determine the level of a standard and how the standard applies to the learning skill or knowledge competency. Credits and Levels Credits are a numerical value assigned to a unit standard that represents the estimated time (about 10 hours) needed for a typical learner to demonstrate that all specified outcomes, (assuming no previous knowledge or skills) have been met.

Bridge construction is a demanding application requiring heavy hot rolled and plate welded sections. These types of sections often fall outside the range of standard sections and plates held by local steel distributors. To aid bridge designers in their choice of materials, information is provided in this article for non-standard plate sizes and large hot rolled I sections, which are available to Japanese Standards.

Design Yield Stress vs Mill Certificate Yield Stress

Written by Clark Hyland on November 27th, 2007.      0 comments

Occasionally the question is asked as to whether a steel that has been certified to a lower steel supply grade classification eg. G250 can be accepted as complying with a higher grade such as G300 on the basis that the Mill Test Certificate associated with its batch has a higher yield and ultimate tensile strength than the minimum required for the higher grade. The answer revolves around the issue of confidence levels in the materials properties derived from large and small statistical samples.

Composite Steel Beam Behaviour with Precast Rib Flooring

Written by Allistair Fussel on November 27th, 2007.      0 comments

Floors consisting of precast ribs supported on structural steel beams and in situ structural topping are a common form of composite floor construction. In this article guidance is given on the modifications required to previously published design guidance for computing shear stud capacities to adapt them for use with precast rib flooring systems. In addition consideration will be given to steel beam top flange stability during construction using this type of flooring system. COBENZ 97 is a popular spreadsheet based programme used for steel composite beam design. Explanation is given to allow designers to use this programme to design composite floor systems utilising precast ribbed floor systems

Steel Availability in New Zealand

Written by Clark Hyland on November 20th, 2007.      0 comments

There are three main purchase options for structural steel sections and plates in the New Zealand market depending on the project scale. The first and second ex - stock supply options are normally more costly than the third indent supply option because of overhead costs such as handling, storage and financing. Other issues should also be considered such as steel quality levels. Sometimes it is better to pay a little more for quality products from known reputable suppliers rather than risk poor end application performance. Fluctuations in demand and supply around the world can affect availability and price.
