Scenario

A client has purchased a large site in a suburban setting, located in a leafy suburb surrounded with modern architectural dwellings. The client has appointed an architect to design 10 semi-detached two storey houses. The local planning authorities have indicated the proposals must complement the surrounding area with a maximum ridge height of 7.5m adhered to, to match existing adjacent properties.

Working as part of the design team you will produce drawings showing an architectural detail, floor layouts and elevational details. The drawings produced will be sufficient to satisfy the requirements of the local planning and building control authorities. You will make changes to the external elevation, where appropriate, including window design, door design and external finish.

The client would like an additional design option with an attached orangery on each house type.

Specification notes for construction:

• Walls: Cavity wall construction comprising; 100mm outer clay facing brickwork skin, 150mm cavity with pumped insulation beads, 100mm inner concrete blockwork skin with plastered finish.

• Roof: 30 degree pitched trussed roof comprising; 200mm × 38mm trusses spaced at 400mm centres, 200mm x 38mm ceiling joists spaced at 400mm centres supported on 100mm × 50mm timber wall plate. Natural slates.

• Floor Construction: Solid concrete floor comprising; 100mm concrete slab, 125mm floor insulation, 25mm to perimeter of slab, 1200 gauge damp proof membrane, 100mm subfloor concrete on 20mm blinding with 150mm crusher run hardcore below.

GENERAL MARKING INSTRUCTIONS

General Marking Instructions

IntroductionMark schemes are intended to ensure that the GCSE examinations are marked consistently and fairly. The mark schemes provide markers with an indication of the nature and range of candidates’ responses likely to be worthy of credit. They also set out the criteria which they should apply in allocating marks to candidates’ responses.

Assessment objectivesBelow are the assessment objectives for Construction.

Candidates must:

AO1 recall, select and communicate their knowledge and understanding of concepts, issues and terminology;AO2 apply skills, knowledge and understanding in a variety of contexts and in planning and carrying out investigations and tasks; andAO3 analyse and evaluate evidence, make reasoned judgements and present appropriate conclusions.

Quality of candidates’ responsesIn marking the examination papers, examiners should be looking for a quality of response reflecting the level of maturity which may reasonably be expected of a 16-year-old which is the age at which the majority of candidates sit their GCSE examinations.

Flexibility in markingMark schemes are not intended to be totally prescriptive. No mark scheme can cover all the re-sponses which candidates may produce. In the event of unanticipated answers, examiners are expected to use their professional judgement to assess the validity of answers. If an answer is particularly problematic, then examiners should seek the guidance of the Supervising Examiner.

Positive markingExaminers are encouraged to be positive in their marking, giving appropriate credit for what candidates know, understand and can do rather than penalising candidates for errors or omissions. Examiners should make use of the whole of the available mark range for any particular question and be prepared to award full marks for a response which is as good as might reasonably be expected of a 16-year-old GCSE candidate.

Awarding zero marksMarks should only be awarded for valid responses and no marks should be awarded for an answer which is completely incorrect or inappropriate.

Marking CalculationsIn marking answers involving calculations, examiners should apply the ‘own figure rule’ so that candidates are not penalised more than once for a computational error.

Types of mark schemesMark schemes for tasks or questions which require candidates to respond in extended written form are marked on the basis of levels of response which take account of the quality of written communication.

53

Other questions which require only short answers are marked on a point for point basis with marks awarded for each valid piece of information provided.

Levels of responseTasks and questions requiring candidates to respond in extended writing are marked in terms of levels of response. In deciding which level of response to award, examiners should look for the ‘best fit’ bearing in mind that weakness in one area may be compensated for by strength in another. In deciding which mark within a particular level to award to any response, examiners are expected to use their professional judgement. The following guidance is provided to assist examiners.

• Threshold performance: Response which just merits inclusion in the level and should be awarded a mark at or near the bottom of the range.

• Intermediate performance: Response which clearly merits inclusion in the level and should be awarded a mark at or near the middle of the range.

• High performance: Response which fully satisfies the level description and should be awarded a mark at or near the top of the range.

Quality of written communicationQuality of written communication is taken into account in assessing candidates’ responses to all tasks and questions that require them to respond in extended written form. These tasks and questions are marked on the basis of levels of response. The description for each level of response includes reference to the quality of written communication.

For conciseness, quality of written communication is distinguished within levels of response as follows:

Level 1: Quality of written communication is basic.Level 2: Quality of written communication is good.Level 3: Quality of written communication is excellent.

In interpreting these level descriptions, examiners should refer to the more detailed guidance provided below:

Level 1 (Basic): The candidate makes only a limited selection and use of an appropriate form and style of writing. The organisation of material may lack clarity and coherence. There is little use of specialist vocabulary. Presentation, spelling, punctuation and grammar may be such that intended meaning is not clear.

Level 2 (Good): The candidate makes a reasonable selection and use of an appropriate form and style of writing. Relevant material is organised with some clarity and coherence. There is some use of appropriate specialist vocabulary. Presentation, spelling, punctuation and grammar are sufficiently competent to make meaning clear.

Level 3 (Excellent): The candidate successfully selects and uses the most appropriate form and style of writing. Relevant material is organised with a high degree of clarity and coherence. There is widespread and accurate use of appropriate specialist vocabulary. Presentation, spelling, punctuation and grammar are of a sufficiently high standard to make meaning clear.
