APWA Corporate Member Directory of Products and Services (alphabetical listing) The APWA Corporate Member Directory of Products and Services is provided as a service by the American Public Works Association to its members to assist in identifying the corporate members that represent the consulting, service, and manufacturing firms serving the public works industry today. It is by no means an attempt to list all of the firms serving the industry, only those that are APWA members as of February 7, 2001. The alphabetical listing appears first, followed by the categorical listing on page 71 (due to space limitations, address and contact information appear in the alphabetical listing only). The APWA Reporter makes every effort to achieve accuracy, but cannot be held responsible for inadvertent omissions or incorrect entries. If any errors are detected, please notify the Membership Department as soon as possible so that the APWA records may reflect the corrections immediately. Membership can be reached at 1-800-848-APWA. 3 Dimensional Contracting, Inc. Mr. Kenneth F.
