Case Studies & Criterion Examples

TxDOT - Embedding INVEST in Contracting for the Corpus Christi Harbor Bridge: The Texas Department of Transportation (TxDOT) used INVEST during the procurement process for the Harbor Bridge Project in Corpus Christi. TxDOT’s request for proposals (RFP) required that bidders describe how their proposal would meet a “Platinum” rating on the INVEST PD module and a “Silver” rating on the INVEST OM module. The sustainability score, along with price and other factors, was part of the total score for selecting among the four bidders. This provided a strong incentive for bidders to achieve high sustainability at low cost. The winning bidder committed to a range of sustainability practices that will bring tangible benefits to the community.

Arizona DOT - Using INVEST to Integrate Sustainability: The Arizona Department of Transportation (ADOT) decided to use all three modules of INVEST – System Planning, Project Development, and Operations and Maintenance – to help the agency meet its sustainability goals across the transportation life cycle.  ADOT used INVEST to integrate and advance existing sustainability efforts and to push forward new efforts.  INVEST’s comprehensive sustainability framework and criteria helped ADOT institutionalize sustainability across the agency and with local partners through inclusion in manuals, trainings, and awards.  This case study focuses on ADOT’s use of the Project Development module.

  2. Provide a list of all non-road construction equipment used on the project that contains the following information for each piece of equipment:
  • Make and model of each piece of equipment.
  • Operating hours associated with the project.
