Spon's A&B provides comprehensive coverage of construction costs from small-scale alterations and repairs to the largest residential or commercial developments. With competition growing fiercer throughout the industry, the A & B' s unique tender index, which allows updating every three months, will be more valuable than ever before. This is the only price book which publishes details of its cost base in such a way that it can be adjusted to allow for the market conditions that affect building prices. The separate minor works section on coloured paper covers contracts of around u65,000 value.
