Unit 212: Produce setting out details for bench
joinery products

Learning outcomes
• Understand how to interpret information for setting out bench joinery
products.
• Describe types of information used.
• Accuracy of information.
• Reporting discrepancies.
• Overall effects of errors.

Types of information
• Working drawings
• Job sheets
• Specifications
• Schedules
• Technical and manufacturers’ information
• Building regulations

Working drawings
An example of a typical working drawing for a straight flight of stairs.
This type of drawing will give you details such as:
• handrail height
• handrail size
• baluster sizes with horizontal gaps
• headroom required.

Working drawings continued

Job sheets
A job sheet will vary in design and layout from company to company but will always carry
the same information:
• job number
• client name and address
• start and completion date
• type of bench joinery product, ie stairs, window, door
• materials to be used
• type of finish, paint, polish, left unfinished
• cutting list.

Specifications
Specifications or a ‘spec’ as it is normally referred to is a document supplied to a
contractor, joinery manufacturer or other tradesman to ‘tender’ against for the work
described in it.
A tender is a formal written offer to carry out work for a stated fixed price.
An architect or the client will issue it and it will cover:
• all aspects of the work to be priced
• the quality of the workmanship
• the quality of the materials to be used
• the date work is to start and be completed
• terms and conditions regarding payment, retention, penalty clause, etc.
It will have working drawings along with a disclaimer stating that it would need to be
checked against site requirements and sizes for discrepancies.

Programme of work/schedules
Schedules or programme of works are a list of where and at which moment in the job’s
timescale each given task or item of materials should be completed or installed.
Sometimes called a Gantt chart or schedule of works, it is a way of everyone being aware
of when their part of the contract process is to take place or where on the site specific
items are to be installed.
This enables the contractor/
manufacturer to plan and
keep the works on time
and due for delivery or
job completion on
time and within budget.

Technical and manufacturers’ information
Manufacturers’
literature both the
names of the parts
they supply but also
the relationship of
each part of a
staircase to each
other.

Technical and manufacturers’ information
This technical sheet shows the types, sizes, names, styles and variations of handrail
turns, Newell posts and balusters available. Both this and the previous slide are intended
to provide the client with a selection of products to choose from.
Reproduced with permission from Pear Stairs.

Building regulations
Building regulations contain the rules for
building work in new and altered buildings
to make them safe and accessible and limit
waste and environmental damage. These
cover all construction work including bench
joinery products.
The most recent versions of the Approved
Documents for the 14 technical ‘parts’ of
the building regulations’ requirements are
available at www.planningportal.gov.uk

Accuracy and discrepancies in manual drawing practices
Accurately setting out and cross-referencing all information regarding bench joinery to
establish the existence of any discrepancies is very important as errors not seen at the
early stages of setting out can have severe consequences further on in the
manufacturing stages.
Lines drawn like these will give a different inside or outside measurement
than ones drawn like these
This is because of the thickness of the lines which over many increments of the
measurement will make your setting out wrong by a long way. Mistakes of this type can
cause remakes, waste of materials, late delivery and ultimately the possibility of penalty
clauses being enforced, so a sharp pencil at all times is of the utmost importance.

Accuracy and discrepancies (continued)
Lack of accuracy in taking measurements from working drawings or job sheets can also
result in the possible outcomes given in the previous slide.
Discrepancies in the specification, schedule or working drawings should have been
noticed prior to the job sheet arriving with the bench joiner, but things do get missed. An
E with the bottom line accidently missing becomes an F.
An 8 partly rubbed out becomes a 3, so slight errors are possible.
It is essential that any alteration to the job sheet or specification should be written down
and signed by either the line manager, manager, architect or client to ensure
disagreements do not occur on completion.
All errors and discrepancies should be reported to the person directly above you in the
management structure before work continues and it is a good idea to put it down in
writing.
