PROJECT NARRATIVE

Giuliani is part of the Hensel Phelps design/build team chosen by the Purple Line Transit Partners to design and build the Purple Line Rail Yard in Maryland just outside Washington, DC. Giuliani will be providing peer review services with JMT Engineers to review design services by Baker International and M.C. Dean.

Project Description:
The Purple Line is a 16-mile light rail line extending from Bethesda in Montgomery County, Maryland to New Carrollton in Prince George’s County, Maryland. It will provide a direct connection to the Metrorail Red, Green and Orange Lines at Bethesda, Silver Spring, College Park, and New Carrollton.

The second maintenance facility, located in Lyttonsville, MD, is a 17,000 SF operations building.

Giuliani Associates is utilizing BlueBeam Revu to review documents prepared on multiple platforms.  The architectural documents were developed in Autodesk Revit while the engineering documents vary by discipline.  All facilities are being reviewed to conform with applicable national, state and local building codes and standards as well as standards put in place by Purple Line Transit Partners made up of the Purple Line Transit Constructors and the Purple Line Transit Operators.
