Preface
Brickwork for Apprenticeshas been the basic reference book onbrickwork
for generations and a source of information for students/trainees starting
out in his/her chosen career or a trained bricklayer seeking guidance in a
particular area of study.
It has been an honour and a privilege to update this book for a
fifth edition.
As technology advances with ever-increasing speed it has been neces-
sary to produce this fifth edition to keep pace with the ever-changing pro-
gramme of study required by today’s students/trainees.
Some topic areas have been updated, extended or replaced, and new
topics have been added.
Many of the topics covered are required for students/trainees who are
studying for NVQs or CAs in brickwork but is equally useful for those
studying for National and Higher National Certificates and GCSEs in
construction.
The fifth edition contains 17 chapters which offer a structured pro-
gramme of training and information.

1 Craft training
Throughout the 1970s and 1980s there was great pressure for change in
the way a craft skill is learned. Brickwork along with other construction
industry trades has had its centuries-old tradition of Apprenticeship thor-
oughly examined.
There are three factors which have caused this re-examination of the
Apprenticeship system,with a capital ‘A’:
(i) A desire for retraining people who may wish to leave one industry
and enter another
(ii) A growing shortage of school leavers available and wanting to join
construction trades throughout the 1980s, due to a falling birth rate
16 or so years earlier
(iii) A general feeling that just because you ‘missed the boat’ for voca-
tional training when leaving school, you should not be denied the
chance of learning a vocational occupation at any time in later life.
All this is far removed from the traditional arrangement of a school leaver
joining a building company for a straightforward period of three or four
years’apprenticeship, with attendance at a local college of technology, as
the only way into the construction industry.
Very many patterns of vocational training have been proposed and
tried,and continue to be developed at the present time.
Current ET (Employment Training schemes), in operation at college
and training centres for adult learners, are the Government’s response to
change-factors (i) and (iii). Craft skills such as bricklaying,carpentry and
plastering,which involve the use of tools and materials and require judge-
ment of hand and eye, should not be confused with assembly processes.
