PREFACE TO THIRD EDITION
The production of this metric edition completes the metrication and updating of the four Building Construction volumes.
Revisions have been made to all chapters and have been particularly extensive in the following: In the section on steel-framed construction because welding has almost entirely replaced riveting, the details in the Figures show the increasing use of welded joints. The reinforced concrete section has been re-written to take account of the design theory of limit state which has replaced the elastic theory. Chapter 3 on fire protection has been recomposed in the light of new legislation. Details of an industrialised building system are given in Chapter 4. Chapter 10, which includes particulars of soil and waste installations, has been extended.
In this book, which is concerned with the more advanced building techniques, it is important that up-to-date systems are illustrated whilst at the same time giving adequate coverage of older, well-proved systems which must form part of the vocabulary of those engaged in the building industry so long as thirty per cent of expenditure is devoted to repair, maintenance and reconstruction.
One reason for the success enjoyed by this book and the companion volumes is the large size of most of the Figures enabling full delineation of the units of construction; here several of them are new and the remainder have been fully revised.

PREFACE TO FIRST EDITION
Many inquiries have been made regarding the date of publication of this book. It was originally intended, after Volume III, to complete the subsequent volumes within a reasonable period, but for several reasons this was not possible. Their preparation was delayed by the war, and when it became possible to make a fresh start, it was found that a number of completed full-page drawings illustrated details of construction that had become obsolete during the intervening years. These drawings and the relevant descriptive matter were rejected. Again, it was difficult to assess which of the newly introduced building techniques and materials would be able to withstand the test of time; some of them have not survived beyond a short emergency period. It was decided therefore to defer the preparation of Volume IV until a clearer picture could be obtained.
Further, when this series of textbooks was first planned, it was anticipated that each of the later volumes would be devoted to one of the years of an approved advanced course. This is now thought undesirable as it would entail a certain amount of duplication, would break continuity and would not be the best arrangement for easy reference. In this connection, in view of the use of the previous volumes in other European countries, and also in Africa and Asia, the present one has not been limited to building practice at home. For example when an open timber framed roof is required, a glued laminated one (Fig. 60) is likely to be preferred in the United Kingdom instead of the older type (Fig. 59), which is more usual where there is a plentiful supply of large baulk timber.
