Use of Incentive/Disincentive Contracting to Mitigate Work Zone Traffic Impacts, 2012

Incentive/disincentive clauses (I/D) are designed to award payments to contractors if they complete work ahead of schedule and to deduct payments if they exceed the completion time. A previously unanswered question is, “Did the costs of the actual work zone impacts that were avoided justify the incentives paid?” This report answers that question affirmatively based on an evaluation of 20 I/D projects in Missouri from 2008 to 2011. Road user costs (RUC) were used to quantify work zone impacts and included travel delays, vehicle operating costs, and crash costs. These were computed using work zone traffic conditions for partial-closure projects and detour volumes and routes for full-closure projects. Conditions during construction were compared to after construction. Crash costs were computed using Highway Safety Manual methodology. Safety Performance Functions produced annual crash frequencies that were translated into crash cost savings. In considering an average project, the percentage of RUC savings was around 13% of the total contract amount, or $444,389 of $3,464,620. The net RUC savings produced was around $7.2 million after subtracting the approximately $1.7 million paid in incentives. In other words, for every dollar paid in incentives, approximately 5.3 dollars of RUC savings resulted. I/D provisions were very successful in saving RUC for projects with full-closure, projects in urban areas, and emergency projects. Rural, non-emergency projects successfully saved RUC but not at the same level as other projects. The I/D contracts were also compared to all Missouri Department of Transportation contracts for the same time period. The results show that I/D projects had a higher on-time completion percentage and a higher number of bids per call than average projects. But I/D projects resulted in 4.52% higher deviation from programmed costs and possibly more changes made after the award. A survey of state transportation departments and contractors showed that both agreed to the same issues that affect the success of I/D contracts. Legal analysis suggests that liquidated damages is preferred to disincentives, since enforceability of disincentives may be an issue. Overall, in terms of work zone impact mitigation, I/D contracts are very effective at a relatively low cost.

Effective Structural Concrete Repair, Volume 2 of 3, Use of FRP to Prevent Chloride Penetration in Bridge Columns, March 2004

Structural concrete is one of the most commonly used construction materials in the United States. However, due to changes in design specifications, aging, vehicle impact, etc. – there is a need for new procedures for repairing concrete (reinforced or pretressed) superstructures and substructures. Thus, the overall objective of this investigation was to develop innovative cost effective repair methods for various concrete elements. In consultation with the project advisory committee, it was decided to evaluate the following three repair methods: • Carbon fiber reinforced polymers (CFRPs) for use in repairing damaged prestressed concrete bridges • Fiber reinforced polymers (FRPs) for preventing chloride penetration of bridge columns • Various patch materials The initial results of these evaluations are presented in this three volume final report. Each evaluation is briefly described in the following paragraphs. A more detailed abstract of each evaluation accompanies the volume on that particular investigation.

State Government E-Commerce Study Encouraging the Use of Electronic Financial Transactions With the Citizens of Iowa, January 20, 2006

This report was produced in compliance the 2005 Iowa Acts, Chapter 52 passed by the Eighty-First General Assembly, Session One (2005), requiring that it be submitted to the General Assembly by January 20, 2006. The legislative language mandating the report reads as follows: “It is the intent of the general assembly to encourage the use of electronic transactions with regard to the state's dealings with the citizens of Iowa and other persons. The department of administrative services shall develop recommendations, including proposed legislation, to encourage the use of electronic commerce, including the acceptance of credit card payments, with regard to transactions involving the state. The department shall consult with the state treasurer, state entities currently accepting credit card payments, and any other state entities identified as considering the acceptance of credit card payments when developing the recommendations. The department shall deliver a report to the general assembly by January 20, 2006, including any recommendations, proposed legislation, and other related information, including cost information associated with credit card payments.”

Improving Transition Outcomes-An Innovative State Alignment Grant for Improving Transition Outcome for Youth with Disabilities Through the Use of Intermediaries, 2004

Iowa Vocational Rehabilitation Services, a Division of the State of Iowa Department of Education, in partnership with six other state agencies, applied for and was awarded funding for “Improving Transition Outcomes for Youth with Disabilities Through the Use of intermediaries.” This Innovative State Alignment Grant is funded by the Department of Labor, Office of Disability Employment Policy. For clarity and brevity, the Iowa team chose to use “Improving Transition Outcomes” as the project name, thus providing the acronym ITO. Grant funding began October 1, 2003 with the possibility of renewal for five years.
