All the performance criteria must be met and all items in the range statement covered. ASSESSMENT In order to achieve this unit, candidates are required to present sufficient evidence that they have met all the performance criteria for each outcome within the range specified. Details of these requirements are given for each outcome. The assessment instruments used should follow the general guidance offered by the SQA assessment model and an integrative approach to assessment is encouraged. (See references at the end of support notes). Accurate records should be made of the assessment instruments used showing how evidence is generated for each outcome and giving marking schemes and/or checklists, etc. Records of candidates' achievements should be kept. These records will be available for external verification. 5

6 SPECIAL NEEDS In certain cases, modified outcomes and range statements can be proposed for certification. See references at end of support notes.

7 NATIONAL CERTIFICATE MODULE: UNIT SPECIFICATION SUPPORT NOTES UNIT NUMBER: UNIT TITLE: PROVIDING DIMENSIONAL POSITIONING FOR SETTING OUT GROUNDWORK SUPPORT NOTES: This part of the unit specification is offered as guidance. None of the sections of the support notes is mandatory. NOTIONAL DESIGN LENGTH: SQA allocates a notional design length to a unit on the basis of time estimated for achievement of the stated standards by a candidate whose starting point is as described in the access statement. The notional design length for this unit is 40 hours. The use of notional design length for programme design and timetabling is advisory only. PURPOSE This unit is designed to enable the candidate to develop skills and knowledge relating to the skills and practical work involved in measuring and setting out basic rectangular shapes for roads and other mason pavior activities, including basic levelling using a spirit level and straight edge, also the use of simple optical instruments for levelling (Cowley level). SQA publishes summaries of NC units for easy reference, publicity purposes, centre handbooks, etc. The summary statement for this unit is as follows: This unit will help you acquire the skills and knowledge to interpret technical information, position and secure corner profiles and accurately position the corners of basic rectangular building features using basic methods to form right angles. You will learn how to transfer levels to establish vertical dimensions by simple methods and will acquire a good knowledge of safe working practices. CONTENT/CONTEXT The candidate successfully completing this unit will require underpinning knowledge and skills relating to the interpretation of technical information to determine the correct dimensions and locations of rectangular buildings and other features. The unit also deals with methods of locating and establishing 90 corners of rectangular features so that work can be carried out, and the re-establishing of corners as required, as well as methods of transferring levels to establish accurately the correct vertical dimensions of buildings and other features from existing features to the feature being established. 7

8 This unit would be offered to candidates from the construction and related services industries. The skills are transferable within different working environments but the unit is primarily aimed at candidates whose normal place of work would be a roads site, or similar environment. The range statement is applicable to many areas of construction and other related occupations. The competences and underpinning knowledge gained in completing this unit would be transferable across a range of disciplines within the built environment. The unit covers locating, measuring and setting out simple rectangular shapes, using cornerpegs and profiles, and levelling for setting out floor levels using a spirit level, straight edge and simple optical instruments (eg Cowley level). APPROACHES TO GENERATING EVIDENCE The achievement of the underpinning knowledge required for this unit would be assisted by the use of slides and videos, and hands-on experience. Tutors/trainers should demonstrate practical elements step-by-step until the candidate feels confident enough to attempt them on his or her own. Safety factors, where relevant, should be thoroughly emphasised. Supervisors and employers could also play an important part in assisting candidates to generate evidence. ASSESSMENT PROCEDURES Candidates will be able to provide evidence of performance using a variety of methods. These will include: - performance at work (recorded in the Candidate's Achievement Record or other methods); - performance in training (recorded in the Candidate's Achievement Record or other methods); - simulated exercises (skills/progress tests results); - past achievement/experiences eg. letters of endorsement; past certificates or testimonies from previous employers. Evidence gathered from the workplace will be the preferred method; however there may be situations where this is inappropriate or the evidence is insufficient. Supplementary evidence will also be required to demonstrate the underpinning knowledge related to the competences in the unit. PROGRESSION This unit forms part of both level II and III SVQs in Construction: Mason Pavior. Each unit is a free standing unit and units are not necessarily taken in a prescribed order, although there may be a logical sequence to the acquisition of the skills and knowledge concerned. To gain either award, the candidate must successfully complete all of the units laid down for the SVQ, details of which can be obtained from SQA. 8
