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.

Unit title: Mathematics for Construction
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.

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 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.

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.
Guidance on the delivery and assessment of this Unit
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.

Higher National Unit specification: support notes
Unit title: Construction Technology: Specialist Systems
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 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.
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.

Unit Assessment (4 hours total)
This takes the form of three different assessment papers, one covering the content of Outcome 1 and lasting one hour duration, one covering the content of Outcome 2 and lasting one and a half hours duration and finally a combined assessment paper covering the content of Outcomes 3 and 4 and lasting one and half hours duration.
Guidance on the delivery and assessment of this Unit
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.
Opportunities for developing Core Skills

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.

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 Select and describe forms of masonry and timber frame wall construction and finishes. 2 Describe the performance requirements, materials, function and construction of the principal
components in a building. 3 Select and describe forms of floor construction and sketch their junctions with other building
elements.4 Select and describe forms of pitched and flat 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: Industrial/Commercial Superstructure � Construction Technology: Specialist Systems
This Unit at SCQF level 6 is a mandatory unit in the HNC Construction and all HND Built Environment awards.
The three units mentioned above have been developed as an integrated suite of units to meet all the 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 provide important underpinning knowledge, understanding and skills in 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 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 Construction Technology units and because the assessment pack for this particular unit is based on the knowledge and/ or skills and list of topics for each of the Outcomes.
The list of topics is given below. Lecturers 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 achievement of candidates in this Unit.

Guidance on the delivery and assessment of this Unit
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.
Opportunities for developing Core Skills
The following grid provides a general guide to opportunities for the development of Core Skills in this Unit. Opportunities for the development of Core Skills at the output level are more fully identified in the Core Skills Signposting Guide.

HN Unit (DW5H 34): Construction Site Surveying A 9
Higher National Unit specification: support notes (cont)
Unit title: Construction Site Surveying A
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.

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.
HN Unit (DW53 34): Construction Materials and Specification 9
Higher National Unit specification: support notes (cont)
Unit title: Construction Materials and Specification
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.
Unit Assessment (7 hours total)
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.

HN Graded Unit (DX20 34): Construction: Graded Unit 1 4
Higher National Graded Unit Specification: Instructions for designing the assessment task and assessing candidates
Graded Unit Title: Construction: Graded Unit 1
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.
HN Graded Unit (DX20 34): Construction: Graded Unit 1 5
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.

Unit title: CAD: 2D I
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 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.

Guidance on the delivery and assessment of this Unit
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.
Opportunities for developing Core Skills
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).

General information for candidates
Unit title: CAD: 2D I
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.

HN Unit (DW4P 33): Building Services: An Introduction8
Higher National Unit specification: support notes
Unit title: Building Services: An Introduction
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 Demonstrate an understanding of the selection and design of above and below ground drainage systems.
2 Demonstrate an understanding of the selection and design of hot and cold water supply and distribution systems.
3 Produce annotated sketches of the supply and distribution of electricity.4 Select and produce annotated sketches of appropriate space heating systems.5 Describe home electronic security systems.
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.
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.

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

Guidance on the delivery and assessment of 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.

General information for candidates
Unit title: Architectural Design Sketching and Drawing
This Unit is designed to enable you to develop competence in graphical communication techniques, especially in the field of architectural drawing and sketching. In addition, you will also develop a knowledge and understanding of basic architectural design concepts and elements.
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 you 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 that you understand the basic design and construction concepts.

General information for centres (cont) 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 all outcomes shall be assessed by a question paper details of which are given at the end of each outcome under the heading ‘Assessment guidelines’. The assessment papers should be composed of a suitable balance of short answer, restricted response and structured questions. Assessment 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. An exemplar instrument of assessment and marking guidelines has been produced to provide examples of the type of evidence required to demonstrate achievement of the aims of the Unit and to indicate the national standard of achievement at SCQF level 7.

HN Unit (DW55 34): Construction Technology: Industrial/Commercial Superstructure 8
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.
