      <title>Develop Best Practice to Improve CRCP Performance near Transverse Construction Joints</title>
      <link>https://rip.trb.org/View/2652074</link>
      <description><![CDATA[The research team will develop best practices to enhance the performance of continuously reinforced concrete pavement (CRCP) near transverse construction joints (TCJs). To support this effort, the research team will identify key construction variables that affect concrete compaction quality near TCJs through a combination of literature review, surveys, field investigations, and statistical analysis. Based on the findings, the research team will develop evidence-based recommendations to ensure acceptable concrete compaction quality and performance of manually constructed TCJs. Upon approval by the Texas Department of Transportation (TxDOT), the research team will propose revisions to the statewide standard specifications, CRCP design standards, and quality control procedures related to TCJs.]]></description>

      <description><![CDATA[The research team will provide a framework to minimize project issues through improved Constructability Reviews (CRs). The research team will develop a cost/benefit analysis to justify CRs on projects of all scopes. The research team will develop a Guidebook of Best Practices will be developed to help the Texas Department of Transportation (TxDOT) improve construction plan quality and minimize project durations and costs. The Guidebook will discuss using knowledgeable construction personnel to review, ensuring adequate time for reviewing, ensuring clear and relevant comments that designers consider and implement, and ensuring that new lessons are continuously communicated back to design teams.]]></description>

      <title>Develop Best Practices for Temporary Pavement Design and Construction</title>
      <link>https://rip.trb.org/View/2652070</link>
      <description><![CDATA[The research team will develop best practices for the design and construction of detours and traffic handling sections. Detours can be designed as a (i) completely new short-term pavement structure, (ii) by using the existing pavement, for example a traffic shift including the shoulder as part of travel lane, (iii) as part of stage construction, and (iv) as a combination of new, stage, and existing. Premature pavement failures continue to occur on detours during construction. The cost to repair pavement failures on detours can significantly impact the construction budget because repairs are reactionary (not planned), there is limited space to both work, and shift or move traffic within. Traffic estimation for the design of temporary detours can be challenging, and clear guidance needs to be developed for accurate pavement design. The research team will produce best practices for evaluation of existing pavement used as detours, pavement design methods, and construction practices that will help designers, engineers, and inspectors make better decisions resulting in successful projects.]]></description>

      <title>Synthesis of Information Related to Highway Practices. Topic 57-15. Institutionalizing Innovations and their Associated Skillset from Alternative Contracting Methods</title>
      <link>https://rip.trb.org/View/2630495</link>
      <description><![CDATA[Project delivery methods have evolved significantly in recent decades as public owners seek to accelerate schedules, reduce claims, encourage innovation, and incorporate life-cycle considerations. State departments of transportation (DOTs) increasingly use alternative contracting methods (ACMs), such as construction manager/general contractor (CM/GC), design–build (DB), progressive design–build (PDB), and public–private partnerships (P3). These approaches often require closer collaboration between designers and contractors, rely on performance specifications, and provide opportunities to pilot new practices such as 3D design and building information modeling. While some states have institutionalized these innovations, practices vary and are not widely shared. A synthesis is needed to document how ACMs have supported innovation in design and construction and to identify the staffing, skills, and training needed to implement such efforts.

The objective of this synthesis is to document state DOT practices on using CM/GC, DB, and PDB project delivery methods to inform future advances and innovative design and construction practices.

Information to be gathered includes (but is not limited to): (1) Use of ACMs, their evolution, and their impact on efficiency, cost, and industry adoption; (2) Innovative solutions enabled by ACMs, including common patterns, applications, and benefits; (3) Programmatic changes in design and construction practices resulting from ACM-driven innovations; (4) Processes and procedures DOTs and state highway administrations (SHAs) use to identify, evaluate, and institutionalize innovations; and (5) Skillsets, knowledge, and training strategies needed to support innovation and leadership in ACM implementation.

Information will be gathered through a literature review, a survey of state DOTs, and follow-up interviews with selected DOTs for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.

      <description><![CDATA[This project will fund a pilot project using the collaborative digital stationing program, OnStation, to complement existing New Mexico Department of Transportation (NMDOT) e-Construction technologies. The digital stationing software will be deployed in two districts for use on multiple construction projects for two years. The software will be deployed on mobile electronic devices for use by field inspectors, supervisors, and project managers. Software users will receive training before usage. Users will have the ability to access digital stationing and software features in the field and the project offices. The software deployment and usage will be a complete project. By piloting this software in two of the six Districts in New Mexico, the NMDOT can ensure that the software will be fully functional and a good fit for use in the state of New Mexico. In the future, if the deployment is successful, the software will be used in all six NMDOT Districts. ]]></description>

      <title>E-Ticketing Technologies for Efficient Asphalt Ticket Collection and Quantity Calculation</title>
      <link>https://rip.trb.org/View/2596426</link>
      <description><![CDATA[The Federal Highway Administration (FHWA) Every Day Counts program has highlighted e-Construction as a proven innovation to shorten the project delivery process, enhance roadway safety, reduce traffic congestion, and integrate automation. The New Mexico Department of Transportation (NMDOT) has implemented many e-Construction innovations. The use of e-Ticketing software on construction projects will complement existing NMDOT e-Construction technologies.   
The decision was made to use an e-Ticketing platform by Haulhub Technologies on NMDOT projects during the 2024 project season. Biweekly meetings with Haulhub and the NMDOT e-Ticketing implementation team commenced in January 2024. User accounts for the implementation test were created for training and testing purposes.  An NMDOT landing page with a picture and a quote from the technology champion was created as an initiative introduction to contractors and vendors. 
Two Haulhub-led e-Ticketing training sessions were scheduled with construction crews and audit sections throughout the state. The sessions were held virtually and covered how to interact with ticket data on the mobile application online (how to mark tickets as delivered, input notes, and take pictures) and offline, how to submit a missing ticket report, and how to interact with the web interface including flex grid overview and daily and delivery reporting options.
A list of construction and audit users was sent to Haulhub for account creation in preparation for the training sessions. Once the accounts were created, users were able to interact with the e-Ticketing platform in advance of the training sessions. This interaction allowed users to formulate questions to ask during training sessions.   
E-Ticketing was optional for contractors starting on the July 2024 bid letting. When projects were let and subsequently awarded, the contractor was allowed to use e-Ticketing technology on their project. The contractor was reimbursed for the cost of any associated equipment via a bid item in the contract and submitted invoices. Contractors were notified of the potential for e-Ticketing use on projects via the Notice To Contractors (NTC). Information on the use of e-Ticketing was also dispersed through partnership associations with the Associated Contractors of New Mexico (ACNM) and the Asphalt Pavement Association of New Mexico (APANM). Contractor use of e-Ticketing will be mandatory starting in the September 2025 bid letting for all projects over 10,000 tons of asphalt.

      <link>https://rip.trb.org/View/2576319</link>
      <description><![CDATA[Premature pavement failures have occurred on several widening projects, including shoulder widenings, conversion of two-lane roadways to Super 2 sections, and other safety enhancements. Repairing these early failures is time-consuming, expensive, disrupts traffic, and poses safety hazards. Key contributing factors include poor-quality materials, poor joint construction, and inadequate drainage which could have been avoided through proper pavement condition assessment, design, and construction practices. The research team will develop detailed guidance to document and implement better widening practices across the Texas Department of Transportation (TxDOT).]]></description>

      <title>Synthesis of Information Related to Airport Practices. Topic S01-31. United States Airport Experience with Multi-Disciplinary Program and Project Teams



</title>
      <link>https://rip.trb.org/View/2458786</link>
      <description><![CDATA[Airports continually focus on practical and functional needs of the airport environment to address a multitude of issues and opportunities. These issues and opportunities range from in-house programs to large-scale capital projects and initiatives, or establish programs to address small-scale everyday issues. These programs and projects take time to envision, build consensus, and deliver; and most airports utilize a mix of approaches and team management methodologies to accomplish these tasks within a demanding schedule and constrained budget. However, some airports have established a process to bring together a multi-disciplinary team to engage all stakeholder groups from the development to the completion of the program or projects. Engaging a diverse team with a collaborative decision-making process provides a shared understanding of the issues and opportunities for all stakeholders. Airports of all sizes can benefit from understanding the process of establishing a multi-disciplinary team, including how airports identify responsibilities of each team member and keep the team and stakeholders engaged throughout the life of the project.

The objective of this synthesis is to document airport practices and processes in assembling and maintaining multi-disciplinary program and project teams adaptable for in-house to large-scale capital projects and initiatives. The audience for this synthesis is for a broad spectrum ranging from small-General Aviation to large-hub airports. ]]></description>

      <title>Evaluation of the Ohio Department of Transportation's Small Business Enterprise Program
</title>
      <link>https://rip.trb.org/View/2431740</link>
      <description><![CDATA[The Ohio Department of Transportation (ODOT) is committed to fair and equal opportunities for firms of all sizes to do business with the state. The Small Business Enterprise (SBE) Program was established to ensure that small businesses receive fair opportunities to participate in ODOT contracting and consulting activities as prime contractors. It is a race/gender-neutral set-aside program that restricts competition for prime contracts on certain federally funded highway construction and design contracts (e.g., culvert replacement, geotechnical design, environmental consulting) to small businesses that have been certified through the program. SBE firms must be prequalified with ODOT to bid on SBE set-aside projects. The SBE must perform or exercise responsibility for at least 30% of the total cost of its contract with its own workforce. While it is a federal requirement to have an SBE element as part of the Disadvantaged Business Enterprise (DBE) program, the design and implementation of the SBE element is completely at ODOT's discretion, however, the process must be approved by the Federal Highway Administration (FHWA). ODOT's current SBE program was developed in 2015. While some individuals view the program as being successful, concerns have been expressed that the pool of SBE contractors is small resulting in a lack of competitive bids on construction projects.  Research is needed to evaluate ODOT's SBE program to ensure it is effective and meets the desired outcome.

The goal of this research is to evaluate ODOT's SBE program, determine its effectiveness and make recommendations for improvements. Objectives of this research include the following: (1) determine the current state of practice for SBE programs and establish best practices; (2) provide a baseline assessment of ODOT's SBE program's performance from its inception in 2015 to present day; and (3) provide recommendations for enhancements in the design and implementation of ODOT's SBE program which includes both certification requirements and the implementation of the program. This research will provide critical insights into how other recipients of transportation federal funding are structuring and managing their SBE programs and how ODOT's program can become more effective and efficient at facilitating competition by fostering productive relationships with SBEs. Findings from this research will identify potential improvements in the program that will not only help ODOT ensure compliance but may also serve to make the SBE program more robust and competitive while maintaining ODOT's ability to carry out design and construction programs in a cost effective manner.

      <title>Synthesis of Information Related to Highway Practices. Topic 56-21. Practices Related to Construction Contingency



</title>
      <link>https://rip.trb.org/View/2384698</link>
      <description><![CDATA[State DOTs are interested in understanding the state of practice for establishing construction contingencies for highway projects. Contingency is defined for the purpose of this synthesis as a predetermined amount of money set aside to cover unexpected costs, changes, or risks that may arise during the project construction phase. Contingency funds serve as a financial buffer to ensure the project can address unforeseen challenges without requiring additional funding approvals.

The integration and management of contingency funds by state DOTs are typically influenced by risk tolerances, specific project conditions, and project delivery methods whether managed by the owner, shared, or designated to contractors.

The objective of this synthesis is to document state DOT practices related to project contingency analysis, development, and use for various project delivery methods, ie. Design-Bid-Build (DBB), Design-Build (DB), Construction Manager/General Contractor (CM/GC), Progressive Design-Build (PDB), and Job Order Contracting (JOC)/Indefinite Delivery, Indefinite Quantity (IDIQ).

For identified project delivery methods, information to be gathered includes (but is not limited to): (1) Written guidelines, policies, practices for contingency analysis, development and use; (2) Methods, tools, and processes used for contingency analysis and risk-based cost estimation; (3) Distinction between contingencies and allowances;
(4) Contingency tracking and management practices; and (5) Past performance of project contingency use.

Information will be gathered through a literature review, a survey of state DOTs, and follow-up interviews with selected DOTs for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.

      <title>Movable Bridge Construction Requirements</title>
      <link>https://rip.trb.org/View/2286630</link>
      <description><![CDATA[There are approximately 800 highway movable bridges in service in the United States per the current National Bridge Inventory database, spread across 33 states. Of the total inventory of existing highway movable bridges in service, over 20 percent are classified as in poor condition and more than 300 exceed 70 years of age.

The lifecycle costs of movable bridges are highly influenced by construction quality, which is, in part, a function of the adequacy of the technical specifications by which a project is executed. The American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications for Movable Highway Bridges, last updated in 1988, contained limited information on construction, primarily related to machinery. This document was replaced by the AASHTO LRFD Movable Highway Bridge Design Specifications in 2000, which does not contain specifications for construction. Since there are no AASHTO documents that address movable bridge construction, movable bridge owners would benefit from a comprehensive national document. Research is needed to develop comprehensive construction requirements for new and existing movable bridges.

The objective of this research is to develop construction requirements for new and existing movable bridges. It shall cover all components of movable bridges including (1) structural, (2) mechanical, and (3) electrical.]]></description>

      <title>Synthesis: Pavement Widening Best Practices</title>
      <link>https://rip.trb.org/View/2256148</link>
      <description><![CDATA[Texas Department of Transportation (TxDOT) has observed premature pavement failures on several widening projects, including shoulder widenings, conversion of two-lane roadways to Super 2 sections, and other safety enhancements. Repairing these early failures is time-consuming, expensive, disrupts traffic, and poses safety hazards. Key contributing factors include poor-quality materials, poor joint construction, inadequate drainage, differential settlement, etc. These issues could have been avoided through proper pre-evaluation, design, and construction practices; but detailed guidance which methods to employ, which can be project specific, is not readily available to district personnel. Therefore, there is a need to document and implement better widening practices.
The research team will synthesize the best practices for pavement widening by conducting the following research objectives: reviewing the literature for effective widening practices; reviewing current widening practices employed by TxDOT, including: pre-design pavement evaluation, pavement layer and cross-section design, materials, project plans, specifications, and estimates, and construction practices; evaluating previous widening projects both in good and poor condition; identify issues and practices that can lead to premature failure, and practices that should be adopted more widely; and developing comprehensive guidelines and modifications to specifications.]]></description>

      <title>Determine Effectiveness of Construction Management Plans</title>
      <link>https://rip.trb.org/View/2255827</link>
      <description><![CDATA[A Construction Management Plan (CMP) is a document that describes the project execution plan and sequence of construction activities that can be performed in the project considering pending clearances related to unclear utility conflicts, right-of-way (ROW) acquisition, ROW encroachments, ROW relocation, and/or outstanding railroad agreements. Texas Department of Transportation (TxDOT) CMPs are required for projects where the estimates for certification and permit clearance extend beyond three months after letting. One of the main goals of CMPs is to mitigate the risk of construction delays. Since the implementation of CMPs a few years ago, TxDOT has not conducted a thorough review of their effectiveness to date. Therefore, the main objectives of this research project are to conduct a review of TxDOT CMPs, verify the potential impact of TxDOT CMPs on change orders and claims, compile lessons learned, and develop recommendations to make TxDOT CMPs more effective. A guidebook and training materials will be developed to facilitate implementation by districts, divisions, consultants, and contractors.]]></description>

      <title>Implementation of Constructability Reviews for Highway Construction Projects in KDOT: Best Practices and Key Lessons</title>
      <link>https://rip.trb.org/View/2255785</link>
      <description><![CDATA[Many state departments of transportation (DOTs), including Kansas Department of Transportation (KDOT), are continually facing challenges of increasing technical complexities, regulatory restrictions, and pressures to deliver quality products on time and within budget. These challenges create a schedule-driven environment during the project development process that may lead to errors, omissions, and constructability problems. To overcome such challenges, state DOTs often seek input from industry representatives to identify constructability issues and improve the project development process across different phases, including environmental, design, construction, and maintenance. The intent of constructability reviews is to identify ambiguous specifications, refine project design, increase project construction efficiency, and potentially reduce disputes, cost overruns, and delays. 
It is important to note that there is a difference between a constructability review and a plans review. A plans review is a traditional industry term that applies to design quality control and quality assurance (QC/QA) reviews of the design plans and other project-design documents during pre-construction. A plans review typically involves checklists that address format, compliance, consistency, calculations and data, and other aspects of the plans. A constructability review focuses on the optimum use of construction knowledge and experience in planning, design, procurement, and field operations to achieve the overall project objective. An effective constructability review offers several key benefits, including reduced cost, shorter schedules, improved quality, better control risk, fewer claims, and fewer change orders. However, there is a depletion of valuable construction knowledge among DOT personnel. In fact, many state DOTs, including KDOT, lacks staff with experience and knowledge of project constructability. To address this essential need, the proposed research will identify and evaluate effective practices for KDOT to conduct constructability reviews and evaluate the long-term value of constructability and industry input.]]></description>

      <title>A Comprehensive Literature Review of Stay-In-Place Form for All Types of Bridge Elements as a Means to Reduce the Demand on Skilled Workers</title>
      <link>https://rip.trb.org/View/2255707</link>
      <description><![CDATA[It is widely known and accepted that the demand on skilled construction work force is higher than ever as the older generation of construction personnel is not getting replaced by a younger generation. This clearly initiates the thought process for exploring creative ways to reduce the demand on skilled workers by introducing construction approaches and practices that minimize the need to employ skilled workmanship. One of such innovative techniques serving the bridge construction industry is the implementation of stay-in-place structural forms that are readily available formwork and external reinforcement that eliminates the need to build and remove falsework being in the bridge decks, bridge girders and bridge piers. Because fire is a recognized hazard in these situations, the targeted elements will be conventionally reinforced for redundancy while the Stay-in-Place (SIP) system will be available as the main reinforcement system. In this project, a comprehensive literature review will be performed of all research and existing projects using SIP form technology. Furthermore, the project will identify specific negative issues with SIP forms, such as problems with inspection or with corrosion, and the corresponding mitigations that might be available. These issues will be addressed individually and the known or proposed solution will all be documented. The proposed research will target a comprehensive state-of-the-art literature review of all the bridge elements utilizing the SIP technology. This includes but is not limited to bridge deck, bridge girder and bridge pier construction in addition to all the other complementary elements like cross girders. The literature review will include the experimental prototypes as well as the actual project implementations in bridges performed by the United States DOT’s, Canada and the rest of the world. The specific literature review research tasks include: 
(1) Identifying a historical perspective for this technology in each bridge element application to link it to the current state-of-the-art construction techniques. 
(2) Surveying all the full-scale experimental investigations performed highlighting the main take away conclusions. 
(3) Establishing a database of all implementation projects that have utilized this technology in the US, Canada and the rest of the world. 
(4) Performing a comprehensive review of the design documents and construction specifications available to the engineering community 
(5) Building flow charts that facilitates the effective implementation strategies of this technology.
