Abacus Construction Index USA

About this Website

Abacus Construction Index USA brings together in one place recommended sources of information and advice about architecture and construction in the USA. The website is a professionally edited directory, and does not accept payment from websites which are included. It is financed entirely from Google Adsense advertisements, which are clearly identified.

The main part of the website is a set of Product Guides. Each Product Guide is devoted to a single construction product, such as Sliding Doors or Bamboo Flooring. The Product Guide describes the types of product available and their characteristics; selects and describes recommended websites of suppliers, and provides useful links to relevant organisations such as trade associations. The Product Guides may be browsed by product category using the blue navigation buttons to the left.

There is a separate UK version of Abacus Construction Index which can be reached by clicking the blue button on the left marked 'UK Version'.

Abacus Construction Index is edited by Dr. Alex Reid, who qualified as an architect at the University of Cambridge and University College London, and who was from 1994 to 2000 the Director General of the Royal Institute of British Architects, London.
