Assignment Details

Answer the following questions (marks Q1 8×10, Q2 20). You may refer to textbooks and other references to complete the answers, but the response must be in your own words. It is essential that you provide a reference for the source used for each question. Questions answered without a reference will not be marked. Pay attention to the action verb in the question which indicates the type and detail of the response required. Your answers will be assessed and feedback provided.

2.  Choose either 2A or 2B.

 2A. Use the equations provided to calculate the time it takes for an adult male to walk along a 300 m corridor when density of occupant flow is:

1)      0.80 person/m2

2)      0.68 person/m2

3)      0.52 person/m2

4)      Comment on the effect of density on the travel time.

For density D ≥ 0.55 person/m2

 For density D < 0.55 person/m2

 Where:

v is the speed (m/s).

𝑣 = 𝑘 − 𝑎𝑘𝐷

𝑣 = 0.86𝑘

a is a constant (0.266 m2/person).

D is density of occupant flow (person/m2).

k is the velocity factor (see Table A1).

 Table A1. Parameters for evacuation speed estimation

 2B. Referring to Approved Document B (Volume 2, Table 3.2 and Diagram 2.6):

1)   A building with six above ground floors is served by two escape stairs without lobby protection. What is the minimum (required) width of the escape stairs if each floor accommodates 90 persons?

2)   A building with five above ground floors is served by three escape stairs with lobby protection. What is the minimum (required) width of the escape stairs if each floor accommodates 250 persons?

3)   A building with ten above ground floors is served by two escape stairs with lobby protection. What is the minimum (required) width of the escape stairs if each floor accommodates 180 persons?

4)   A ground floor storey exit serving 520 persons shares a common final exit with the stair obtained in (3) above. Calculate the required final exit width using the relevant formula.

The word limit of the whole report is less than 2000 words per student. This excludes

footnotes but includes quotations. The word count must be printed on the top right-hand corner of your work.

 Remember:

·       You must keep to the word limit.

·       You must demonstrate that you have met the learning outcomes.

·       As you construct and present your work, consider the assessment criteria.

Presentation Instructions

It is your responsibility to ensure that your work is neatly and accurately presented. The work must be:

·       Word-processed

·       Single sided

·       1.5 or double line spaced

·       Arial 12-point font

·       Justified

·       Page numbered

·       On A4 paper

·       Margins left and right 3 cm

·       Attached to a cover sheet.

Marks may be deducted for failure to follow these instructions. Please look at the Student Guide to Assessment for more information.

 Referencing

All academic writing must be referenced. If you use other people’s ideas without referencing them, you are plagiarizing their work.

Either:

Use the Harvard system of referencing within your text. This will take the form: surname, year of publication, page number, and is enclosed within brackets, for example (Bradley 1998, 277). At the end of your work, you should provide an alphabetical list of all the works you cite.

 Or:

 Use the Numeric System of referencing within your text. At every point in the text where a reference is made, insert a number (in brackets or superscript) and then list the references numerically at the end of your work.

Plagiarism

 The use of work produced for another purpose by you, working alone or with others, must be acknowledged.

 Copying from the works of another person (including Internet sources) constitutes plagiarism, which is an offence within the University’s regulations. Brief quotations from the published or unpublished works of another person, suitably attributed, are acceptable. You must always use your own words except when using properly referenced quotations.

 You are advised when taking notes from books or other sources to make notes in your own words, in a selective and critical way.

 Submission

 The work should be submitted:

• with a front cover sheet (detailing the module code and title, report title, learning outcomes, and date);

• electronically through Blackboard, which you can also check your successful submission copy straight after.

Every attempt will be made to ensure that the work will be marked and available for collection within 3 working weeks.

 The assignment is worth 50% of the total module assessment.

 Learning outcomes

This assessment tests your ability to meet the learning outcomes as described in your Module Descriptor, specifically:

2. Critically assess risks associated with fire in complex residential properties.

4. Critically assess active and passive fire protection systems in complex residential properties.

5. Appraise external cladding risks and determine if a PAS 9980 survey is required.
