In Barry’s Introduction to Construction of Buildings we provided an introductory chapter that set out some of the basic requirements and conditions relevant to all building projects, regardless of size and complexity. In this volume the emphasis shifts from domestic to larger-scale buildings, primarily residential, commercial and industrial buildings constructed with loadbearing frames. This is supported with information on fit out and second fix, lifts and escalators, and off-site construction. Many of the principles and techniques set out in the introductory volume are, however, still appropriate to this volume. Similarly, many of the technologies described here are also used in smaller buildings. Thus we would urge readers to consult both volumes of the Barry series. In this introductory chapter we start to address some additional, yet related, issues, again with the aim of providing some context to the chapters that follow.
