    Utility Relocation and Coordination for Purple Line

    Maryland Transit Administration

    As a sub-consultant on the Purple Line GEC team, RJM provided utility coordination support along the proposed Purple Line transit alignment located in Montgomery & Prince George’s counties for approximately 20 miles. Services included obtaining existing and proposed utility mapping information from utility companies, researching the utility mapping, field verification of overhead line locations and pipe directions in drainage manholes, and preparing MicroStation utility files.

    For gas lines along this project, RJM contacted Washington Gas to acquire gas line as-built drawings and design manuals, and identified potential conflicts requiring relocation. RJM updated model utility files, adjusted gas line layouts based on discussions in utility coordination meetings, and provided QA/QC reviews for relocation designs.
