Construction projects are plagued by inefficiencies, mistakes, and delays that account for $200 billion annually in the US. New business-to-business companies are creating websites for individual building projects that allow all involved parties to access blueprints, orders, and specifications online, permanently recording all information to reduce mistakes and delays. Companies like Bidcom and BuildNet are also developing industry-wide marketplaces that integrate the systems of builders and suppliers to further streamline the ordering process, reduce human error, and cut costs for the fragmented construction industry. These online hubs aim to become fully-fledged marketplaces that facilitate transactions between all buyers and sellers in the industry.
