Accelerated bridge construction (ABC) is an innovative construction technique used to accelerate the construction of new bridges, as well as the renovation/replacement of existing bridges. Due to the benefits offered by ABC, transportation authorities have a higher preference in executing an accelerated approach over conventional bridge construction. The execution of an accelerated approach has differences when compared to the conventional approach, and it is important to identify such differences for the successful implementation of ABC projects. However, there have been no studies to identify such execution differences. Therefore, this study was conducted to identify execution plan differences relevant to ABC. For this purpose, an extensive literature review was conducted to prepare a preliminary list of execution plan differences. Then, a questionnaire survey was administered with the industry experts, who were previously involved in the execution of ABC projects, to validate the preliminary list. Based on the literature review and the responses from questionnaire survey, this study identified 61 execution plan differences relevant to ABC in different phases of execution. This study is expected to benefit owners, contractors, and road/bridge users for successful execution of ABC projects.

To succeed at developing a nationwide Integrated Ocean Observing System (IOOS), stakeholders in academia, government, and industry must forge and maintain strategic partnerships. The South Florida Ocean Measurement Center (SFOMC) is such a partnership model and mutually beneficial collaboration that is conducting year-in and year-out major at-sea operations, sustaining the operation of a complex array of sub sea sensors, and providing the maintenance and the shore-based infrastructure to support both. The transformation of a longstanding, narrowly focused, and somewhat antiquated (but highly capable) Navy test and evaluation facility is described. Formerly plagued with a decreasing customer base and increasing operational costs, the Center's transformation into this now fully integrated coalition has mitigated these forerunners of extinction while answering both Navy and academic needs. The successful partnership has resulted in modern facilities, a broad customer base, and steadily decreasing costs of operation. Examples are provided that demonstrate the ability of the Navy's South Florida Testing Facility (SFTF) to realize user cost savings and to aid in the convergence of interest and capabilities among a variety of user groups toward the solution of problems of national concern, including naval research, homeland security, and environmental stewardship.

Reduced Mobility

Traffic disruption from bridge construction has been reduced to several hours through the development of methods characterized as accelerated bridge construction. Associated risks and additional activities involved in the accelerated construction increase initial project cost. This additional cost is offset by the benefits of reduced mobility impact time. Traditionally, the savings in user cost from reduced mobility impact time are used to justify the additional cost of accelerated construction implementations. This paper presents a comprehensive cost model for bridge construction that incorporates the economic impact on surrounding communities and businesses. This economic impact model incorporates user costs, environmental costs, and business revenue changes. The M-100 over the CN Railroad bridge replacement project in Potterville, Michigan, is presented here as a case study to demonstrate the application of economic impact analysis concepts and procedures. This bridge replacement was the third slide-in (i.e., lateral slide) project completed by the Michigan Department of Transportation. Economic impact analysis revealed the benefits of the implementation of the lateral slide bridge construction method at this site.

Modularization is a well-known construction technique where sections of the job are moved from on-site to a fabrication shop. Previously, the researchers identified the 21 most influential Critical Success Factors (CSFs) for successful modularization and quantified the degree of each CSF’s accomplishment by conducting a survey with 19 subject matter experts, and a case study with three modular projects. Through this methodology, the findings relied on the experience of experts. However, still missing from the understanding of modularization CSFs is a validation of the current degree of each CSF’s accomplishment by examining actual modular projects using a sufficient number of samples. This paper presents a comparison of CSF accomplishment degree between 25 actual sample projects (project based) and the industry experts’ survey results (experience-based estimation). The study results indicate that the industry experts made a good estimation of the current occurrence degree of each CSF. The study did identify, however, three significantly overestimated CSFs and three underestimated CSFs. The three most overestimated CSFs are Owner-Furnished/Long Lead Equipment Specification, Cost Savings Recognition, and O&M Provisions. The three most underestimated CSFs are Contractor Experience, Management of Execution Risks, and Transport Delay Avoidance. This study will help the industry to 1) better understand modularization CSFs and their accomplishment statuses; 2) achieve higher modular project performance by accomplishing the CSFs

Open Trench

When a pipeline is installed under flexible pavement structures using open excavation and fill methods, the excavation can result in premature pavement deterioration due to difficulties associated with trench site restoration and soil and asphalt compaction. In developed areas, trenchless construction methods have become a popular alternative to open trench excavation because of reduced surface disruptions and reinstatement costs, a shorter construction period, and significantly reduced traffic delay costs associated with construction by saving time in construction operations. This paper summarizes a recent study that examined how pipeline installations on 1- and 7-year-old Ontario municipal collectors and minor arterial roads impact the 30-year life cycle of a pavement in terms of performance, future maintenance costs, and user-delay costs. Study results indicated that (1) approximately 30% reduction in pavement life can be expected once an excavation is made in a road; (2) increased maintenance and rehabilitation costs for excavating 1-year-old pavement were determined to be approximately Can$146/m2, and the costs for excavating 7-year-old pavement vary from Can$85 to $140/m2; and (3) the use of trenchless technology with good construction practices has the potential to significantly reduce road maintenance and rehabilitation costs and user-delay costs.Key words: pavement performance, open excavation, trenchless technologies, user-delay costs.
