Blueprints at Addison Circle is a steel sculpture located in Addison, Texas inside a 133-foot-diameter (41 m) roundabout. The sculpture consists of 25 poles and five art panels. The sculpture weighs 410,000 pounds (190,000 kg) and required 650 US gallons (2,500 l) of custom "Sharpie blue" paint. The sculpture is more than 4 stories high and 140 feet (43 m) across. It was designed by landscape architect Michael Van Valkenburgh and artist Mel Chin with the aid of LeMessurier Consultants, and was fabricated and erected by Big D Metalworks of Dallas. The poles weighing 9,000 pounds (4,100 kg) were made in Houston, Texas and the tapered cones at the top of the poles were made in New Jersey. The structure was dedicated on April 13, 2000. The design is said to resemble the branching pattern of a grove of oak trees. The five art panels were designed using actual blueprints from Addison’s municipal buildings, parks, bridges, and water pumping facilities. Total cost for the sculpture was $2.1 million. The nighttime lighting was designed by Stephen Bernstein of Cline Bettridge Bernstein Lighting Design.
