And a few extracts from the Preface written by the Chairman of NBS Ltd, Sir Robert Matthew,
Publication of the first edition of NBS is the culmination of a long period of intensive effort by many people and organisations in the building industry...
...The NBS presents architects, structural engineers and quantity surveyors with a unique opportunity to re-appraise and develop their specification practice. The benefits will come to them and to the industry as a whole in the form of better and more efficient building. I strongly recommend its use.
