|Use of Design-Build Strategies
||The $1.1 billion DFW Connector project in Grapevine will be substantially completed in summer 2013 after four years, instead of the eight- to 10-year original estimate. Contracting with one developer to integrate design and construction offered the flexibility of design adjustments during the construction phase.
The Design-Build approach also eliminated the time-consuming step of bidding and contracting the construction phase after the design is complete.
|4-6 years in construction time||Construction|
|Adjustment to Federal Yellow Paint Policy
||Dalton Pratt, a regional fleet manager in TxDOT's North Region Office, identified $2 million in cost savings by suggesting TxDOT stop using a special color of paint called Federal Yellow for its heavy equipment fleet.

|Use of Competitive Bid Process to Sell Bonds
||Recently TxDOT successfully priced just over $1.1 billion in State of Texas Highway Improvement General Obligation (“HIGO”) Bonds with an overall borrowing cost of 3.37%.
The bond sale included $100 million of taxable bonds sold via competitive sale. This is the first time TxDOT has used the competitive bid process to sell bonds, considered an industry best practice.
