Henry Riley LLP, acting as Construction Project Managers and Employers Agents for ASDA since 2005 have assisted in the administration of numerous schemes on The-Project extranet. The systems features, ease of use, availability, reliability and level of service have provided the construction teams with many years of improved co-ordination and better communication of design information. We find that even new and inexperienced users are able to retrieve and contribute information to the extranet with little and in most cases no instruction.
