CLQ Capacity Planning: More Than Counting Beds

Use several capacity limits, not one calculation

A sensible capacity study should calculate or review several possible limits:

• sleeping-space limit;
• sanitary-facility limit;
• room and gender-separation limit;
• circulation and safety limit;
• common-facility limit;
• utilities and infrastructure limit;
• certificate or authority limit; and
• practical operating limit.

The lowest defensible limit usually controls the usable capacity.

Sleeping-space calculation

The 2020 regulations state minimum sleeping space generally of:

• 3.6 square metres per employee for accommodation other than a dormitory; and
• 3.0 square metres per employee for dormitory accommodation.

The calculation should use the relevant sleeping area, not the total building floor area. Corridors, toilets, kitchens, stairs, stores and common areas should not be counted as worker sleeping space.

Room shape, doors, windows, furniture and circulation also affect whether the theoretical area can be used properly.

Bed and personal-storage requirements

Every employee should be provided with the required personal facilities, including a suitable bed and an individual lockable cupboard. Capacity planning should allow sufficient space to use these items safely and accessibly.

Avoid layouts where:

• beds block doors or escape paths;
• cupboards cannot be opened;
• upper bunks interfere with ventilation or fixtures;
• occupants must cross another sleeping space to enter or leave; or
• maintenance access is impossible.

Toilets and bathrooms

Sanitary facilities frequently become a capacity constraint. Review the applicable ratios and arrangement for the accommodation type, including:

• number of toilets;
• number of bathrooms or showers;
• male and female separation;
• distribution across floors or blocks;
• accessibility and maintenance access;
• water pressure and supply; and
• drainage and sewage capacity.

A large sleeping floor with inadequate sanitary facilities should not be treated as having the capacity indicated by area alone.

Gender and room allocation

Act 446 requires separate accommodation for employees of opposite genders. Capacity planning should therefore consider the expected gender mix, room allocation flexibility and separate supporting facilities.

A facility with a nominal capacity of 200 may not be able to accept every combination of male and female occupants without leaving some rooms or facilities unused.

Common and supporting areas

Plan enough space and infrastructure for:

• cooking or food service;
• dining;
• rest and common activities;
• laundry and drying;
• waste storage and collection;
• cleaning materials;
• management or person-in-charge functions;
• sick or isolation arrangements where required;
• security and access control; and
• vehicle, bus or pedestrian movement.

These areas affect worker welfare and daily operating quality even when they do not directly appear in the sleeping-space formula.

Utilities and infrastructure

Check whether the proposed occupancy can be supported by:

• water storage and pressure;
• electricity and load capacity;
• sewage or septic systems;
• waste volume;
• ventilation and heat management;
• internet or communication needs;
• fire water and safety systems; and
• transport movements at shift changes.

Infrastructure designed for a much smaller previous use can make the theoretical room capacity unrealistic.

Certified, design and operating capacity

Use separate terms:

• Design capacity: the number assumed by the designer or feasibility study.
• Certificate or approved capacity: the capacity accepted or stated through the relevant process.
• Operational capacity: the number the facility can manage safely and effectively.
• Available capacity: operational beds not currently occupied or reserved.

Do not market design capacity as available certified capacity.

Consider employer acceptance

Employers may impose practical requirements beyond the minimum legal standard, such as:

• maximum travel time;
• lower room density;
• dedicated employer blocks;
• specific security arrangements;
• transport staging;
• meal services;
• recreational facilities;
• reporting and incident procedures; and
• room-allocation flexibility.

The commercially usable capacity may therefore be lower than the highest possible certificate capacity.

Build a room-by-room schedule

A useful schedule should state:

• room identifier;
• sleeping area;
• accommodation type;
• calculated area limit;
• proposed beds;
• gender allocation;
• nearby sanitary facilities;
• ventilation and window information; and
• final accepted operating capacity.

Reconcile the room schedule against the total toilets, bathrooms, common facilities and certificate information.

Common capacity mistakes

• Dividing total gross floor area by the sleeping-space minimum.
• Counting corridors and common areas as sleeping area.
• Adding beds without increasing toilets or infrastructure.
• Ignoring gender allocation and room flexibility.
• Treating every physical bed as certified and available.
• Failing to update capacity after renovation or room-use changes.
• Advertising capacity before the certificate and operating plan are confirmed.

A sensible next step

Prepare a floor-by-floor room and facility schedule. Calculate the sleeping-space limit, sanitary limit and practical operating limit separately, then use the lowest supportable figure for further planning.
