AutoCAD Helps Drive Infrastructure Design
Parsons Brinckerhoff uses AutoCAD to help design and visualize the Presidio Parkway project in San Francisco.
By David Cohn
Editor's note: Through a sponsorship by Autodesk, Cadalyst editors bring you this feature, part of a special series of articles that highlight the role of AutoCAD and 2D design in today's demanding CAD work flows. Watch for the next installment next month.
To say that Parsons Brinckerhoff is a large architecture, engineering, and construction management firm certainly would be an understatement. Founded in 1885 and headquartered in New York City, the firm employs more than 14,000 people and has 150 offices worldwide. One of the company's earliest projects was the original Interborough Rapid Transit (IRT) line of the New York City subway. Today, Parsons Brinckerhoff is a leader in the design and operation of infrastructure, and its list of projects is huge — both in number and scope — and includes transit systems in Atlanta, San Francisco, and New Delhi; airports in Hong Kong and Washington, D.C.; the North American Air Defense Command (NORAD) in Colorado; the H-3 highway in Hawaii; and the Detroit–Windsor Tunnel. Parsons Brinckerhoff also is a major Autodesk customer and runs its own in-house authorized training center.
To say that AutoCAD is a major factor in most Parsons Brinckerhoff projects, therefore, also would be an understatement. According to Rebecca Arsham, training manager at Parsons Brinckerhoff's CAD services group in San Francisco, Parsons Brinckerhoff uses "just about any and every product that we can in the Autodesk suite to get the job done." Nowhere is this integration of the wide array of Autodesk software more evident than it is in the Presidio Parkway project.
The Presidio Parkway project involves the replacement of the existing south access road to the Golden Gate Bridge. Originally built in 1938, the roadway known as Doyle Drive and Route 101 has reached the end of its useful life. (Image courtesy of the Presidio Parkway project.)
The Presidio Parkway project involves the replacement of the existing south access road to the iconic Golden Gate Bridge in San Francisco. The existing roadway, presently known as both Doyle Drive and Route 101, is structurally and seismically deficient and must be replaced. Each weekday, more than 100,000 vehicles travel between Marin County and San Francisco over the Golden Gate Bridge along the 1.5-mile-long Doyle Drive. The roadway is facing the same problem that threatens other parts of our nation's infrastructure — the ravages of time and continual use. Originally built in 1936, Doyle Drive has reached the end of its useful life. Read more »
