- First progressive design-build horizontal project in AZ
Working in partnership with adjacent neighborhood groups and a developer constructing a new mall for this area, Pima County embraced the progressive design-build delivery method for the widening of Skyline Drive. The scope included the widening and reconstruction of 2 miles of Skyline Drive as well as improving 3,100 feet of Campbell Avenue North and 1,300 feet of Orange Grove Road. Skyline is a four-lane divided roadway between Chula Vista Road and Orange Grove, and a six-lane divided roadway between Orange Grove and Campbell Roads. The construction scope included surveying; drainage and extensive new underground utility improvements (120,000 linear feet); raised medians; curb, gutter and sidewalk; multi-use lanes; intersection improvements; landscaping and public art; noise and retaining walls; and quality assurance and quality control services.
This project exemplified the success of design-build for all stakeholders. A formal partnering agreement was implemented not only with the owner and design-build team, but with the community stakeholders along the corridor as well all of the public and private utility companies.The integrated project team (owner, designers, contractor and utility companies) also co-located in an office adjacent to the roadway and the neighborhoods being impacted by construction.
The project was completed 285 days ahead of schedule including all design, environmental permitting, and right-of-way acquisition. The core value of design-build was proven by working together to save time, save money, alleviate frustration and misunderstandings, promote creative thinking, provide solutions and build relationships of trust between community, government and industry.
The Skyline team took a proactive approach to public and community relations that was unheard of and turned what is normally an unpleasant construction experience for neighbors, businesses and the traveling public into something where everyone felt they were part of the process and their needs, wants and concerns were being addressed.
