The PBX is a trade association that has been serving the commercial construction industry since 1886. We are now a full-service online construction news service supplying the most accurate information about construction opportunities from the design phase through contract awards. Our website includes continuously updated project news, bid documents, addenda, reprographic services, online take-off tools, sophisticated searching, tracking and notification features. Although our primary service is the online planroom we also have a fully-equipped physical planroom for your convenience. Our long-term presence in the Western Pennsylvania area results in a more quality reporting service than is available through other non-local services. We have been operating for over 100 years and have a proven track record of stability, accuracy and fair pricing.
