FV3201 IndividualAssignment Brief

Assignment Details

This assignment is based around the principle of ASET-RSET and guidance provided in BS7974. You must therefore utilise BS7974 and the relevant Published Documents that support BS7974 to answer this assignment.
Part A –50%

• On the basis of the plansand information provided below determine the Required Safe Escape Time (RSET)from the MEZZANINE area following the guidance of BS7974 (i.e. perform the RSET part of an ASET-RSET calculation).

• Provide a commentary alongside the calculation that discusses the calculation process and explains each of the different terms/elements used, their importance and provide justification for your choice.

Part B – 50%

• For the same case explain how the Available Safe Escape Time (ASET) could be determined. You should discuss the different approaches that could be used, potential design fire scenarios and the criteria (e.g. Tenability limits) that could be used to determine the ASET. Please note that an actual ASET calculation is not a requirement of this assignment.

Scenario

When answering Parts A and B above the following information should be used:

• The area in question is a storage warehouse for building materials (which may include combustible materials).

• The building will have dimensions 60m by 52m by 14m high (See Figure 1).

• The building will have two exits (each 1.8m wide) from the ground floor (See Figure 1).

• The building will only be accessed by trained staff and not members of the public

• The owner of the warehouse wants to add a mezzanine floor (see area in red on Figure 2).

• The floor of the mezzanine will be located 9m above the ground floor level.

• The mezzanine will be occupied by up to 20 members of staff and there will be no disabled access.

• A single open stair (1.8m wide) will be the only way to access/exit the mezzanine(see Figure 2).

• Important note: the plans do not show the location of storage/obstacles. You should ensure that your calculations/discussion etc. take account of this.
