Higher National Unit specification: support notes


This part of the Unit specification is offered as guidance. The support notes are not mandatory.

While the exact time allocated to this Unit is at the discretion of the centre, the notional design length is 40 hours.

Guidance on the content and context for this Unit

This Unit has been written in order to allow candidates to develop knowledge, understanding and skills in the following areas:

1 The application of algebraic techniques to manipulate expressions and solve equations commonly found in construction (10 hours) Roots and powers. Factors, removal of brackets. Index values. Linear, Simultaneous, Quadratic equations. Indices and logarithmic functions. Scientific / engineering notation.Graphs: y = mx + c, y = axn,Equations: A = P(1 + r/100)t, ax2 + bx + c = 0 Indices: Positive, Negative, Fractional

2 The use of trigonometry and circular measure formula to solve commonly found problems in construction (15 hours) Trigonometry: Pythagoras, Sine ratio, Cosine ratio, Tangent ratio, Sine rule, Cosine rule. Circular measure: Arc length (r�), Sector area (1/2r2�), Segmental area (1/2r2[� - Sin�]).�

Measure of centre: Mean, Median Measure of spread: Inter-Quartile deviation, Standard deviation Normal Distribution: Calculations involving standardised variables

Mathematics for Construction has been incorporated within the first year of the HNDs in Architectural Technology, Building Surveying, Construction Management, Quantity Surveying and Facilities Management awards as a mandatory Unit. It is considered that a Unit in Mathematics is essential to support other areas of work in the awards, notably the surveying and structural principles areas.

In designing this Unit the unit writers have identified the range of subjects they would expect to be covered by lecturers. The writers have also given recommendations as to how much time should be spent on each outcome. This has been done to help lecturers decide the depth of treatment that should be given to the list of topics attached to each outcome. Although it is not mandatory for centres to use this list of topics it is strongly recommended that they do so to ensure continuity of teaching and learning across the Mathematics Units and because the exemplar pack for this unit is based on the knowledge and/or skills and list of topics in each of the Outcomes.


Higher National Unit specification: support notes (cont)


Guidance on the delivery and assessment of this Unit

As the Unit provides core mathematical principles, which underpin many of the studies done in the HND awards , it is recommended that the Unit be delivered towards the start of these awards.

The Unit has been designed to incorporate sufficient time to allow lecturers to teach the core Mathematics contained within the Unit. The unit has also been written to allow candidates sufficient time to practice what they have learnt through appropriate formative assessments and exercises.

Delivery of the Unit should focus on, and be within the context of commonly encountered problemsin the construction industry.

Details on approaches to assessment are given under evidence requirements and assessment guidelines under each outcome in the Unit specification: statement of standards section. It is recommended that these sections be read carefully before proceeding with assessment of candidates.

The content of this Unit is such that it is recommended that if the Unit is assessed by one holistic assessment instrument then assessment takes place at the end of the Unit delivery time.

Open learning

This Unit could be delivered by distance learning, which may incorporate some degree of on-line support. However, with regard to assessment, planning would be required by the centre concerned to ensure the standard and authenticity of candidate evidence. Arrangements would have to be put in place to ensure that assessment whether done at a single or at multiple events was conducted under controlled, supervised conditions.

To keep administrative arrangements to a minimum, it is recommended that a single assessment paper (taken by candidates at a single assessment event) be used for distance learning candidates.

For information on normal open learning arrangements, please refer to the SQA guide Assessment and Quality of Open and Distance Learning (SQA 2001).

Candidates with additional support needs

This Unit specification is intended to ensure that there are no artificial barriers to learning or assessment. The additional support needs of individual candidates should be taken into account when planning learning experiences, selecting assessment instruments or considering alternative Outcomesfor Units. For information on these, please refer to the SQA document Guidance on Alternative Assessment Arrangements for Candidates with Disabilities and/or Additional Support Needs, which is available on SQA’s website: www.sqa.org.uk.

1 The process of site investigation2 Describing methods of ground water control. 3 Describing methods of improving the ground 4 Describing forms of foundation and basement construction.

This Unit has been developed as part of a group of construction technology units. There are three other units in the group entitled:

� Construction Technology: Domestic Construction,� Construction Technology: Industrial/Commercial Superstructure � Construction Technology: Specialist Systems

This Unit at SCQF level 7 is a mandatory unit within all the HNC and HND Built Environment and Civil Engineering awards.

The three Units mentioned in the previous paragraph have been developed as an integrated suite of units to meet all the construction technology requirements of the HNC and HND Built Environmentawards. However, this does not preclude the use of one or more of these units in other awards where award designers feel this to be appropriate. As well as providing a substantial course in construction technology principles these units also provide important underpinning knowledge, understanding and skills for other parts of the HNC and HND Built Environment awards

In designing this Unit the unit writers have identified the range of topics they would expect to be covered by lecturers. The writers have also given recommendations as to how much time should be spent on each outcome. This has been done to help lecturers to decide what depth of treatment should be given to the topics attached to each of the Outcomes. Whilst it is not mandatory for a centre to use this list of topics it is strongly recommended that it does so to ensure continuity of teaching and learning across the Construction Technology units and because the assessment exemplar pack for this Unit is based on the knowledge and/or skills and list of topics in each of the Outcomes.

The list of topics is given below. Lecturers are advised to study this list of topics in conjunction with the assessment exemplar pack so that they can get a clear indication of the standard of achievementexpected of candidates in this Unit.




1 Describe the process of site investigation. (10 hours)

Site investigation: � Desk studies � Walk-over survey (site reconnaissance) � Direct ground investigation:

— planning the investigation — extent, depth of exploration and choice of method— trial pits— auger holes— bore holes — light percussion boring — hollow stem auger — rotary core drilling

Soil mechanics: This should be a brief introduction covering the topics below, however lecturers shall decide the depth of treatment required which may depend on the award programme.

� soil formation and nature � soil description and classification — Rock, granular soils, cohesive soil, organic soil � fill (or made ground): engineered and non-engineered fills

In-situ testing:penetrometers or cone penetration test � probing, using lightweight dynamic

Note for tutors

Many standard texts are available covering foundation design and construction. Tutors should refer students to BRE publications particularly in the ‘Good Building Guide’ series for simple foundations of low rise buildings. Many Contractor’s web sites are available and students should be encouraged to search these web sites and examine the case studies available.

The current British Standards are a useful reference when covering basement construction. A copy of the British Standards should be available for access by the students.

Unit Assessment (4 hours total)

This takes the form of three different assessment papers, one covering the content of Outcome1 and lasting one and half hours duration, one covering the content of Outcome 2 and Outcome 3 and lasting one hour duration and finally an assessment paper covering the content of Outcome 4 and lasting one and half hours duration.


As this Unit provides core construction technology which underpins much of the studies done in other areas of HNC and HND Built environment awards it is recommended that the Unit be delivered towards the start of these awards.

Where this Unit is incorporated into other Group Awards it is recommended that it be delivered in the context of the specific occupational area(s) that the award is designed to cover.

Details on approaches to assessment are given under Evidence Requirements and Assessmentguidelines under each Outcome in the Higher National Unit specification: statement of standards section. It is recommended that these sections be read carefully before proceeding with assessment of candidates.

1 Sketching and describing methods of underpinning buildings. 2 Sketching and describing methods of façade retention and shoring of structures. 3 Describing methods and materials used to over clad and over roof buildings. 4 Explaining the viability of the range of off site construction solutions.

This Unit has been developed as part of a group of construction technology units. This Unit at SCQF level 8 is a mandatory unit within many of the HND Built Environment awards.

The group of units mentioned in the previous paragraph have been developed as an integrated suite of units to meet all the construction technology requirements of the HNC and HND Built Environmentawards. However, this does not preclude the use of one or more of these units in other awards where award designers feel this to be appropriate. As well as providing a substantial course in construction technology principles these units also provide important underpinning knowledge, understanding and skills for other parts of the HNC and HND Built Environment awards

In designing this Unit the unit writers have identified the range of topics they would expect to be covered by lecturers. The writers have also given recommendations as to how much time should be spent on each outcome. This has been done to help lecturers to decide what depth of treatment should be given to the topics attached to each of the outcomes. Whilst it is not mandatory for a centre to use this list of topics it is strongly recommended that it does so to ensure continuity of teaching and learning across the Construction Technology units and because the assessment exemplar pack for this Unit is based on the knowledge and/or skills and list of topics in each of the Outcomes.

As this Unit provides core construction technology that underpins much of the studies in other areas of HNC and HND Built Environment awards, it is recommended that the Unit be delivered towards the start of these awards.

Where this Unit is incorporated in other group awards it is recommended that it be delivered in the context of the specific occupational area(s) that the award is designed to cover.

The outcomes are presented in a logical sequence of Walls, Components (Windows/Doors etc) Floors and Roofs. It is recommended to deliver Outcome 2 — the installation of Components together with Outcome 1 — Walls, because of the inter-dependent nature of the subject.




The content of the Unit forms the basis for much of the work to be undertaken in the construction technician study programme. It is essential that students are familiar with the basic forms of construction. To this end, the lecture programme should be supplemented with structured visits. Technical literature, current British Standards and the current Scottish Building Standards should also be used extensively to ensure the students understand the basic construction concepts.

This Unit could be delivered by distance learning that may incorporate some degree of on-line support. However, with regard to assessment, planning would be required by the centre to ensure the sufficiency and authenticity of candidate evidence. Arrangements would be required to be put in place to ensure that the assessment, which is required to be a single event, is conducted under controlled and supervised conditions.





This Unit has been designed to allow you to develop knowledge and understanding of low-rise, domestic construction in both traditional and timber frame methods of construction. You will consider the functional and performance requirements of the various elements of low-rise construction and the construction methods and materials that are best suited to meet all the requirements.

Construction Technology: Domestic Construction is designed in such a way that it may be presented as a stand-alone unit. However, as the content of the Unit builds on the knowledge and understanding of foundations and substructure construction gained in the unit Construction Technology:Substructure, it is recommended that the Unit Construction Technology: Substructure is completedprior to the commencement of Construction Technology: Domestic Construction.

This Unit is designed to provide candidates with ‘soft’ underpinning skills required by competenttechnical practitioners who often combine with other disciplines in a project environment. It is suggested that the unit should be studied early in the first year of the programmes. Local site construction activities or local case studies are particularly important in raising awareness of the importance of technical communications within the diverse construction industry. In addition, role-play; oral presentations, and group work encourage discussions and present opportunities to generate appropriate evidence to contribute to the assessment of Core Skills units.

Where available, evidence from the workplace can also be incorporated to enhance the learning outcomes, provided that this evidence is appropriate and authenticated as the student’s own work.

The volume of evidence required for each assessment should take into account the overall number of assessments being contemplated within this unit and the design of the overall teaching programme.

Although assessments must be focused on the individual achievement of each student, group work and role-play activities may contribute to the assessment. Integrative assignments and project work will help to link this unit with other related units.

This Unit provides the candidate with the knowledge and understanding of the basic processes in land surveying for construction purposes. Attention should be paid in the delivery of this Unit to the content of the other units in the programme(s), especially those related to measurement and, in particular, Construction Site Surveying B.




The opportunity to provide evidence of the achievement of a range of key skills will feature stronglyin both formative and summative assessments. Since this unit links with others in the built environment and civil engineering programmes, it should be studied in the first year of a two-yearprogramme. Case studies could usefully be employed to illustrate the practical working context of the material delivered. This might involve practitioners to deal with some aspects of the content or site visits where these are possible. In addition, where the centre has access to land surveying software, this might be used to allow a broader application of the concepts.

Candidates will work in groups for the fieldwork sections of this unit but would normally work individually in other parts of the unit. Candidates should be encouraged to participate in discussion in relation to their own studies or experiences. Assessment may be formative and summative and both may feature as part of the process. Although assessment must be focussed on the individual achievement of each candidate, group work will contribute as appropriate. Integrative project work might assist in linking this unit with other related units. Appropriate attention must be given to health and safety arrangements in relation to the topics covered.

The volume of evidence required for each outcome should take into account the overall number of assessments being contemplated within this unit and the design of the overall delivery programme. In designing the assessment instrument(s) opportunities should be taken to generate appropriate evidence to contribute to the development of core skills elements.

Where available, evidence from the workplace can also be incorporated to enhance the learning outcomes, provided that such evidence is appropriate and authenticated as the candidate’s own work.


Opportunities for the development of Core Skills at the output level are more fully identified in the Core Skills Signposting Guide. The grid below is indicative of the opportunities for core skills development within this Unit.

This Unit at SCQF level 7 is a mandatory unit within all HNC and HND Built Environment awards and HND Civil Engineering award.

In designing this Unit the writers have identified the range of topics they would expect to be covered by lecturers. The writers have also given recommendations as to how much time should be spent on each outcome. This has been done to help lecturers to decide what depth of treatment should be given to the topics attached to each of the outcomes. Whilst it is not mandatory for a centre to use this list of topics it is strongly recommended that it does so because the assessment exemplar pack for this Unit is based on the knowledge and/or skills and list of topics in each of the Outcomes.

The list of topics is given below. Lecturers/tutors are advised to study this list of topics in conjunction with the assessment exemplar pack so that they can get a clear indication of the standard of achievement expected of candidates in this Unit.

1 Describe the manufacture and the properties of building materials. (12 hours)

This Outcome covers the manufacturing processes associated with a range of construction materials and the properties of such materials which has a bearing on their performance. Use should be made of published performance data.

Building materials to be covered should include:

Cement:� Portland cement (including white cement and high early strength cement)� Sulphate Resisting Portland cement.� mention that many other cements are available such as low heat Portland Cement and fly

ash cements

AggregatesConcrete (in-situ and precast) Bricks (clay, concrete and calcium silicate) Blocks (lightweight and dense)




Timber, including timber products such as: � Structural timber composites: Glued laminated timber (Glulam), Laminated Veneer

Lumber (lvl) � Wood-based panels: Plywood, Oriented Strand Board, (OSB) Wood chipboard, Fibre

board, Cement-bonded particleboards

Steel/Aluminium/Lead/Copper/Zinc etc PlasticInsulation materials: (cork, foam glass, mineral wool, rigid polyisocyanurate foam boards, extruding foamed polystyrene, rigid phenolic insulation) BitumenAsphalt

Properties should include: strength, durability, appearance, water resistance, fire resistance, thermal resistance and movement.

Quality control procedures should be stressed.

2 Describe and carry out laboratory tests on building materials and prepare reports. (12 hours)

This Outcome is designed to allow candidates to identify relevant current standards for the testing of materials and to use the procedures described in these standards to undertake a series of material tests in a laboratory.

Candidates may refer to a computer database for information retrieval of the relevant standards for the laboratory test being undertaken.

Material Tests

Fresh Concrete: � slump test � vebe test � flow table test � degree of compactability (test)

Hardened concrete: testing cubes

ammer)�� rebound hammer (Schmidt h

c covermeter� electromagnetiultrasonic test �

Cement:ess (using Vicat apparatus)� determination of setting times and soundn

� determination of strength (mortar prism)




Aggregates:� sieve analysis� moisture content

Masonry Units: � clay masonry units � assessment of dimensional deviation

Timber:� assessment of moisture content using the oven-drying method

Metallic materials: � tensile testing at ambient temperature

All tests must be carried out in accordance with current standards.

Candidates will undertake a minimum of four laboratory tests covering at least three construction materials in which they will describe the test procedure, carry out the test and prepare a laboratory report. It is recommended that at least two of the tests should be carried out on concrete.

For each test, the precise requirements of the test must be covered to completion of the test.

The assessment for this Outcome will be carried out both in the laboratory and in a classroomwriting up the reports. This should be done under controlled supervised conditions.

3 Prepare sample specifications for materials. (9 hours)

This Outcome concentrates on the appropriate specification of three materials: concrete, timberand mortar in accordance with current standards and which will require some explanation in class.

Specifications may be prepared in a format similar to the National Building Specification (NBS). It would be useful if candidates had access to this library of specifications clauses either in electronic format or from a library.

Concrete: The approaches to the specification of concrete in accordance with current standards should be covered, they are: � sdesignated concrete� designed concretes � prescribed concretes

d concretes� standardised prescribeproprietary concretes �

It is intended that this should be a brief introduction covering the five approaches to the specification of concrete; however lecturers shall decide the depth of treatment required which may depend on the award programme.




It is not intended that any depth is given to designed mixes which is a specialist area but lecturers should explain the use of designated concretes and standardised prescribed concretes which are in common use.

Timber: The approaches to the specification of timber should be covered. This should include situations where timber species is not important but strength grade/strength class and treatmentmay be, for example, for floor joists spanning a given distance. In other situations such as in exposed roof trusses timber species will be important.

Therefore, timber species, strength grade/strength class, preservation/treatment, moisturecontent should be covered.

Mortar: The specification of mortar, including the difference cement types that may be used, the specification of fine aggregate, plasticiser, hydraulic lime and water. The specification of mix designations in accordance with current standards should also be covered.


This takes the form of three different assessments, one covering the content of Outcome 1, one covering the content of Outcome 2 and finally one assessment paper covering the content of Outcome 3 and lasting one and half hours duration and be carried out under supervised controlled conditions.

The time duration allocated to Outcome 2 will vary depending on what tests are undertaken and the number of laboratory sessions included. For example, cube testing concrete will require visits to test cubes at 7 and 28 days after the cube has been produced to carry out tests in accordance with current standards.




Work may be undertaken in groups. However, planning would be required by the centre to ensure the sufficiency and authenticity of candidate evidence.

Where available, evidence from the workplace can also be incorporated to enhance the learning outcomes, provided that this evidence is appropriate and authenticated as the student’s own work.

Higher National Graded Unit Specification: Instructions for designing the assessment task and assessing candidates


Conditions of Assessment

The candidate should be given a date for completion of the case study. However, the instructions for the assessment task should be distributed to allow the candidate sufficient time to assimilate the details and carry out the assessment task. During the time between the distribution of the assessmenttask instructions and the completion date, assessors may answer questions, provide clarification,guidance and reasonable assistance. The assessment task should be marked as soon as possible after the completion date. The final grading given should reflect the quality of the candidate’s evidence at the time of the completion date.

The evidence for the project is generated over time and involves three distinct stages, where eachstage has to be achieved before the next is undertaken. Thus any reassessment of stages must be undertaken before proceeding to the next stage.

If a candidate fails the project overall or wishes to upgrade, then this must be done using a substantially different project, ie all stages are undertaken using a new project, assignment, case study, etc. In this case, a candidate’s grade will be based on the achievement in the reassessment.

The candidate should be given a date for completion of the case study. Parameters should be agreedwith the tutor/supervisor by the candidate/s) on a continuing basis providing clarification, guidanceand reasonable assistance.

Each assessment task should be marked as soon as possible after the completion date. The final grading given should reflect the quality of the candidate’s evidence at the time of the completion date, including any oral examination. Reassessment of this Graded Unit should be based on a significantlydifferent assessment task.

At this level, candidates should work independently within the context of a typical working environment. It is up to Centres to take reasonable steps to ensure that the candidates bring their specialist knowledge and experience to the project. For example, Centres may wish to informallyquestion candidates at various stages on their knowledge and understanding of the project/case studyon which they have embarked. Centres should ensure that where research etc, is carried out in otherestablishments or under the supervision of others that the candidate does not receive undue assistance. Candidates should be allowed to use appropriate technology within and outwith the college environment.

To ensure authentication of work it is advisable for candidates to complete a log or diary recording progress and tasks completed. There should be regular meetings between the tutor and candidate(s) to review progress and these meetings should be recorded.

The final evaluation should include an oral examination of each candidates understanding of theevidence submitted. Where possible the involvement of an employer in the oral examination is encouraged.


Higher National Graded Unit Specification: Instructions for designing the assessment task and assessing candidates (cont)

Instructions for designing the assessment task

The assessment task is a project. The project undertaken by the candidate must be a complex task which involves:

� variables which are complex or unfamiliar� relationships which need to be clarified � a context which may be familiar or unfamiliar to the candidate

The assessment task must require the candidate to:

� analyse the task and decide on a course of action for undertaking the project � plan and organise work and carry it through to completion� reflect on what has been done and draw conclusions for the future � produce evidence of meeting the aims which this Graded Unit has been designed to cover

The assessment task should be a case study based project within the context of a domestic building development project (new build or refurbishment). The range of the tasks to be undertaken should bedefined in relation to the context of the particular building development, and what it is reasonable to expect of candidates in the time scales available. The issues selected should focus on the main aims of the HNC course, and the need to demonstrate an ability to integrate knowledge and skills across the mandatory Units in the award.

The investigation should allow the candidate(s) to demonstrate valid and realistic responses to the current and future needs of an ongoing development including, where appropriate, issues of Healthand Safety and sustainability. Safe working practices should be looked at in accordance with current safety codes of practice and regulations. Sustainability should include reference to criteria affecting sustainability, impact of not implementing sustainability on the environment and the legislation promoting sustainability.

NOTE:

Where candidates are progressing from a HNC to a HND programme the Centre may wish to consider that the HND Graded Unit 2 task/s might be an extension of the tasks for the HNC Graded Unit 1. A similar progression might also be considered for candidates progressing through the three GradedUnits credits of a HND.

Guidance on grading candidates

Candidates who meet the minimum Evidence Requirements will have their achievement graded as C— competent, or A — highly competent or B somewhere between A and C. The grade related criteriato be used to judge candidate performance for this Graded Unit is specified in the following table.

While the exact time allocated to this Unit is at the discretion of the centre, the notional design length

is 40 hours.


This is a required Unit of the HNC/D in Computer Aided Draughting and Design but may be

delivered on a standalone basis or as an option to another Group Award. If this Unit is delivered as

part of a Group Award, it is recommended that it should be taught and assessed within the subject area

of the Group Award to which it contributes.

This Unit has been written in order to allow candidates to develop fundamental knowledge,

understanding and skills in basic file management, drawing set up, creation and use of Standard

Template files, creation and editing of objects and production of printed drawings. These skills are

essential to creation of practical 2D drawings within any design discipline.

There is one other Unit in the group entitled CAD: 2D II. The two Units have been developed as an

integrated suite of Units to meet most 2D CAD requirements and can be used in awards as necessary

and where appropriate.

In designing this Unit a range of topics have been included which would be expected to be covered by

lecturers. Recommendations are given below as to how much time should be spent on each Outcome.

This has been done to help lecturers decide what depth of treatment should be given to the topics

attached to each of the Outcomes. Whilst it is not mandatory for a centre to use this list of topics, it is

strongly recommended that it do so to ensure continuity of teaching and learning across the Units.

The assessment exemplar pack for this Unit is based on the knowledge and/or skills and list of topics

in each of the Outcomes as well as covering aspects of the discipline which it is used in, ie Building

Environment.

The list of topics is given below. Lecturers are advised to study this list of topics in conjunction with

the assessment exemplar pack so that they can get a clear indication of the standard of achievement

expected of candidates in this Unit.

Unit Assessment

Outcome 1 to 3 Practical 3 hours

Outcome 4 Practical 2 hours





As this Unit provides basic CAD skills, which requires continual use to obtain proficiency, it is

recommended that the Unit be delivered towards the start or middle of an award so that it may be used

with other Unit requirements.

Where this Unit is incorporated into other Group Awards it is recommended that it be delivered in the

context of the specific occupational area(s) that the award is designed to cover, eg architectural

drawings with Built Environment courses.

Details on approaches to assessment are given under Evidence Requirements and Assessment

guidelines after the Outcomes in the Higher National Unit specification: Statement of Standards

section. It is recommended that these sections be read carefully before proceeding with assessment of

candidates.


Candidates are working to a remit which requires the ability to create and manipulate objects in a

computer aided design environment. Access to, and evaluation of, examples of complex design

drawings would be of value in formative work. Candidates should be able to work unaided in correct

file management: considerations of security and safety should be a routine aspect of good practice.

The selection of appropriate software application packages and the ability to manipulate objects,

dimensions and text is integral to achievement, as are techniques in editing data to meet identified

needs of purpose and context.

Accuracy of interpretation and effective communication of numerical and graphic information

underpins the competencies developed in the Unit, and candidates are assessed on their ability to edit,

to use a full range of dimensioning commands and plot to scale. Some candidates may benefit from

formative opportunities to further develop effectiveness in the understanding, analysis and application

of numerical and graphic data, and the use of software packages or on-line tutorials to reinforce

numeracy skills may be useful. Candidates could additionally benefit from discussions with the class

group and/or assessor in order to encourage analytical evaluation of approaches to the design process.

Open learning

This Unit could be delivered by distance learning, which may incorporate some degree of on-line

support. The candidate would require access to a PC with the appropriate CAD software installed.

With regard to assessment, arrangements would need to be made by the centre to ensure the

sufficiency and authenticity of candidate evidence under controlled conditions. Candidates should

also be made aware of the time commitment to assessment. Outcome evidence may be presented as

an electronic drawing file if creation of a printed version is not possible.

For further information and advice, please refer to the SQA guide Assessment and Quality Assurance of Open and Distance Learning (SQA, February 2001 - publication code A1030).





This Unit specification is intended to ensure that there are no artificial barriers to learning or

assessment. The additional support needs of individual candidates should be taken into account when

planning learning experiences, selecting assessment instruments or considering alternative Outcomes

for Units. For information on these, please refer to the SQA document Guidance on Alternative Assessment Arrangements for Candidates with Disabilities and/or Additional Support Needs, which is

available on SQA’s website: www.sqa.org.uk.





This Unit has been designed to help you to develop knowledge, understanding and basic skills in the

use of Computer Aided Design application software for the creation of two-dimensional drawings. It

will provide a sound basis for progression to other CAD Units. You will learn file management

techniques, standard drawing and editing commands, drawing layout and final printing options. It is

appropriate for use within chosen Group Awards such as Built Environment, Architectural,

Mechanical or Civil Engineering.

There will be a series of practice exercises and drawing tutorials which will logically progress from

simple to complex.

There are two formal practical assessments with times as follows:

Outcome 1 to 3 Practical 3 hours

Outcome 4 Practical 2 hours

The assessments will be supervised and conducted under open-book conditions in which you will be

allowed to take notes, textbooks, etc. into the assessment. You will sit these assessments at prescribed

points during the Unit at the discretion of the lecturer.

This is a practical Unit requiring you to have individual access to a CAD system. A CAD system is

defined as hardware and software, which will enable an operator to generate (and regenerate)

drawings at an acceptable processor speed. A typical minimum hardware configuration would be a

current single user PC fitted with suitable peripherals attached such as a printer/plotter to produce

hard copies of your work. Alternatively other configurations such as networked CAD stations are

acceptable provided they can satisfy the Unit’s criteria.

This Unit has been developed as part of a group of building services units. There are three other units in the group entitled Building Services in Commercial and Industrial Buildings, Building Services Design: Heating, Lighting and Acoustics and Building Services Design: Ventilation & Air Conditioning. This Unit at SCQF level 6 is a mandatory unit within the new HNC and HND Built Environment and Civil Engineering awards.

The three units mentioned in the previous paragraph have been developed as an integrated suite of units to meet all the building services requirements of the new HNC and HND Built Environmentawards. However, this does not preclude the use of one or more of these units in other awards where award designers feel this to be appropriate. As well as providing a substantial course in building services principles these units also provide important underpinning knowledge, understanding and skills for other parts of the HNC and HND Built Environment awards

In designing this Unit the unit writers have identified the range of topics they would expect to be covered by lecturers. The writers have also given recommendations as to how much time should be spent on each outcome. This has been done to help lecturers to decide what depth of treatment should be given to the topics attached to each of the outcomes. Whilst it is not mandatory for a centre to use this list of topics it is strongly recommended that it does so to ensure continuity of teaching and learning across the Building Services units and because the assessment exemplar pack for this Unit is based on the knowledge and/or skills and list of topics in each of the Outcomes.

Unit title: Building Measurement and Cost Studies

Unit code: DW3X 34

Unit purpose: This Unit is designed to enable candidates to gain knowledge and understanding of the processes involved in the preparation of a tender for building works. The Unit begins with the preparation of quantified item descriptions and proceeds to examine the factors affecting labour and plant outputs and how these and other factors such as material costs impact on the overall estimate for the work and the subsequent tender submitted to the Client.


1 Produce quantified items for superstructure walls, together with associated openings and finishes, for a single building of straightforward construction using the current Standard Method of Measurement (SMM) for building works.

2 Describe the factors which affect building costs. 3 Explain the production and adjudication of an estimate for building works.



Recommended prior knowledge and skills: It would be an advantage for candidates to have a basic knowledge and understanding of external wall construction, although this is not essential because the Unit covers all the basic principles. Possession of basic knowledge and understanding may be evidenced by the candidate having obtained a Unit or Units in construction technology at HN level.

Core Skills: There are opportunities to develop the Core Skills of Communication, Numeracy and Problem Solving in this Unit, although there is no automatic certification of Core Skills or Core Skills components.’


HN Unit (DW3X 34): Building Measurement and Cost Studies 1


Assessment: It is possible to assess candidates either on an individual Outcome basis, combinations of Outcomes or by a single holistic assessment combining all Outcomes.

It is recommended that assessment of this Unit should take the form of two separate papers.

Outcome 1 should be assessed individually and last two hours. The assessment paper will require the candidate to prepare a draft Bill of Quantities for the external walls of a single building of straightforward construction.

The assessment for Outcomes 2 and 3 should be combined together into one assessment paper which it is anticipated would take the candidate approximately two hours to complete. This assessment paper will take the form of an assignment which will require the submission of a written report.

The assessment for Outcome 1 should be conducted under controlled, supervised conditions. It should be noted that candidates must achieve all the minimum evidence specified for each Outcome in order to pass the Unit.

This Unit has been designed to introduce you to and develop knowledge, understanding and skills in the measurement and description of quantities for building work. In particular it covers the measurement of external walls, windows and doors. This Unit also explains the process involved in producing an estimate and tender for building work and outlines the factors which affect the costs for building works. Even if you do not intend to follow a career in quantity surveying, this Unit will help you understand how building work is measured and priced by a building contractor.

You will be required to examine building drawings and specification notes and your knowledge of building construction will be enhanced by undertaking this Unit.

By the end of this Unit you will be aware of the many and varied factors which affect the cost of building projects and how the contractor includes for these in his tender for a construction project.

The formal assessment for this Unit will consist of two separate assessment papers lasting a total of four hours. The assessment for Learning Outcome 1, lasting two hours, will be conducted under supervised conditions with access to the current SMM for building works. You will be allowed to take in your own notes and a scientific calculator. The second assessment, covering both Learning Outcomes 2 and 3, will take the form of an assignment requesting you to submit a written report.

It is recommended that the Outcomes in this Unit be completed in the sequence in which they are presented. This does not preclude some integration of the Outcomes during teaching, tutorial and assessment. Videos, slides, photographs etc can be used to illustrate the architectural content of the Unit. Visits to buildings of architectural interest will also contribute to the learning process. Sketching exercises may be undertaken in the classroom and in the field, using different techniques and media.

The use of texts and manuals on architecture and related subjects, available from CIAT, CIOB, RIAS, RIBA and RICS as well as other sources, will provide the basis of the information required bycandidates to complete the assessment tasks.


1 Basic architectural design concepts. 2 Architectural form, function and mass.3 Construction drawing preparation, standards and conventions. 4 Freehand and instrument-aided sketching and illustration.

This Unit at SCQF level 7 is a mandatory Unit within the HNC and HND suite of Built Environment.

In designing this Unit, the Unit writers have identified the range of topics they would expect to be covered by the tutors. The writers have also given recommendations as to how much time should be spent on each Outcome. This has been done to help tutors decide what depth of treatment should be given to the topics attached to each of the Outcomes. Whilst it is not mandatory for a centre to use this list of topics, it is strongly recommended that it does so to ensure continuity of teaching and learning across the suite of Built Environment awards and because the assessment pack for this particular Unit is based on the knowledge and/ or skills and list of topics embraced by each of the Outcomes.

The list of topics is given below. Tutors are advised to study this list in conjunction with the assessment exemplar pack so that they can get a clear indication of the standard of achievementexpected of candidates undertaking this Unit.

The content of the Unit builds on the knowledge and understanding of drawings and sketching gained in the Unit Construction Communications, it is recommended that this Unit be completed prior to the commencement of Architectural Design Sketching and Drawing.

The content of the Unit forms the basis for much of the work to be undertaken in the construction technician study programme. It is essential that students are familiar with the basic principles of design and sketching. To this end, the lecture programme could be supplemented with the use of site visits. Design sketches, construction drawings, technical literature, British Standards and the Scottish Building Standards should be used extensively to ensure the candidate understands the basic design and construction concepts.

This Unit could be assessed holistically by the production of a portfolio of evidence generated by the candidate during designated tutorial time within the centre or in private study time outwith the confines of the centre. Much of the evidence could arise from tasks set by the tutor to elicit appropriate graphical responses that meet the Evidence Requirements demanded by the Outcomes.Some written text will be required to satisfy the descriptive elements of Outcomes 2 and 3.

It is the responsibility of the centre to satisfy themselves that the portfolio of evidence submitted for assessment is entirely original and solely the respective student’s work.

Where available, evidence from the workplace can also be incorporated to enhance the learning Outcomes, provided that this evidence is appropriate and authenticated as the student’s own work.

Higher National Unit specification: support notes Unit title: Construction Technology: Industrial/Commercial Superstructure This part of the Unit specification is offered as guidance. The support notes are not mandatory. While the exact time allocated to this Unit is at the discretion of the centre, the notional design length is 40 hours. Guidance on the content and context for this Unit This Unit has been written in order to allow candidates to develop knowledge, understanding and skills in the following areas: 1 Comparing and describing the range of materials and construction forms available for the

erection of a structural frame. 2 Sketching and describing methods and materials for forming external walls to framed

buildings. 3 Sketching and describing ground, upper floor and stair construction in framed buildings. 4 Sketching and describing forms of roof construction and finishes. This Unit has been developed as part of a group of construction technology units. There are three other units in the group entitled Construction Technology: Substructure, Construction Technology: Domestic Construction, and Construction Technology: Specialist Systems. This Unit at SCQF level 7 is a mandatory unit within the HNC and HND Built Environment award with the exception of the HNC Construction The three units mentioned in the previous paragraph have been developed as an integrated suite of units to meet all the construction technology requirements of the HNC and HND Built Environment awards. However, this does not preclude the use of one or more of these units in other awards where award designers feel this to be appropriate. As well as providing a substantial course in construction technology principles these Units also provide important underpinning knowledge, understanding and skills for other parts of the HNC and HND Built Environment awards In designing this Unit the unit writers have identified the range of topics they would expect to be covered by lecturers. The writers have also given recommendations as to how much time should be spent on each outcome. This has been done to help lecturers to decide what depth of treatment should be given to the topics attached to each of the outcomes. Whilst it is not mandatory for a centre to use this list of topics it is strongly recommended that it does so to ensure continuity of teaching and learning across the Construction Technology Units and because the assessment exemplar pack for this Unit is based on the knowledge and/or skills and list of topics in each of the Outcomes. The list of topics is given below. Lecturers are advised to study this list of topics in conjunction with the assessment exemplar pack so that they can get a clear indication of the standard of achievement expected of candidates in this Unit.

Reviewing and Evaluating 5 Working with Others Open learning This Unit could be delivered by distance learning, which may incorporate some degree of on-line support. However, with regard to assessment, planning would be required by the centre concerned to ensure the sufficiency and authenticity of candidate evidence. Arrangement would be required to be put in place to ensure that the assessment, which is required to be at a single event, was conducted under controlled, supervised conditions. For information on normal open learning arrangements, please refer to the SQA guide Assessment and Quality Assurance of Open and Distance Learning (SQA 2000). Candidates with additional support needs This Unit specification is intended to ensure that there are no artificial barriers to learning or assessment. The additional support needs of individual candidates should be taken into account when planning learning experiences, selecting assessment instruments or considering alternative Outcomes for Units. For information on these, please refer to the SQA document Guidance on Alternative Assessment Arrangements for Candidates with Disabilities and/or Additional Support Needs, which is available on the SQA website www.sqa.org.uk.
