RJM Engineering was responsible for the preparation of design plans and profiles for storm drains, water mains including permit acquisitions, and sewer replacements at Oxon Hill, University of Maryland College Park, Aspen Hill Park, New Carrollton, and Tantallon, Maryland. RJM’s services included the following:
All sanitary sewer design work was in accordance with the WSSC Pipeline Design Manual and WSSC Standard Details.
RJM Engineering, as a sub-consultant, prepared the site piping plans and valve vault structural designs including the appropriate specifications and construction phase services of a new 0.5-million gallon elevated water storage tank to replace the existing Colgate tank, located at 440 Simmons Avenue, Baltimore, Maryland. Piping included a 16-inch tank supply line and an overflow/drain line to the existing storm drain. The project consisted of four stages – site evaluation, preliminary design, final design and engineering services during construction phase, including the following items:
Services also included coordination of underground utility locating/testing services.
.
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.
