Design and Construction Standards

LINEAR CAD MANUAL 2023

The Linear CAD Manual and it's appendices are now available by clicking the links on this page. 

The Linear CAD Manual (LCM) is the primary computer-aided design (CAD) reference for preparing linear design Drawings in the Capital Improvement Program (CIP) of the District of Columbia Water and Sewer Authority (DC Water). The LCM is referenced as required criteria in the Standard Scope of Work Exhibits of the DC Water Professional Services Agreement. The LCM presents CAD Standards to be used to produce all Design Drawings and Record Drawings for linear infrastructure that are produced by DC Water and its consultants.

If you are working on projects for DC Water, contact Kyle Tyler at kyle.tyler@dcwater.com or Calwood.Somers@dcwater.com to obtain pre-approved CAD templates for design drawings.

For more information regarding other standards, contact Bethel Abate at bethel.abate@dcwater.com

First turn of cutterhead signals the start of excavation for the Potomac River Tunnel Project

In a defining moment for one of the District’s largest infrastructure investments, DC Water has marked its next major milestone in the Potomac River Tunnel Project. The first tunnel boring machine, Mary, has launched her northbound journey breaking through the soil to signal the start of excavation.

With the first turn of Mary’s drill-like cutterhead underground, the machine pushed forward to begin tunneling, representing the transition from years of planning and preparation to active tunnel construction on the $819 million project.
