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 drawingsAn 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 sheetsA 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.



SpecificationsSpecifications 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/schedulesSchedules 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’ informationManufacturers’ 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’ informationThis 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.

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 practicesAccurately 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.
