Cost-effective Practices for Off-system and Local Interest Bridges


Book Description

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 327: Cost-Effective Practices for Off-System and Local Interest Bridges examines off-system bridge design, construction, maintenance, financing, rehabilitation, and replacement. For this report, 'off-system' refers to those bridges typically owned and maintained by local agencies, and by state agencies on rural and other low-volume roads.




Field Performance of Timber Bridges


Book Description

The North Siwell Road bridge was constructed during December 1994 in Hinds County, Mississippi. The bridge is a single span, stress laminated T-beam structure measuring 9.1 m (30 ft) in length and 8.7 m (28.5 ft) in width. Performance of the bridge was monitored for 24 months, beginning at the time of installation. Monitoring involved gathering and evaluating data relative to the moisture content of the wood components, force level of stressing bars, and behavior of the bridge under static load conditions. Comprehensive visual inspections were also conducted to assess the overall condition of the structure. Based on field evaluations, the bridge is performing well.










Economic Feasibility of Projects


Book Description

This is a textbook for engineering and management/business undergraduates and postgraduate students and a reference for practicing engineers or managers who are familiar with their projects but less familiar with financial/economic analysis methods. The book is divided into two parts. Part 1 covers all the basic concepts and theories and provides the readers with a good understanding of the financial and economic analysis on the feasibility of projects. Plenty of examples are used to illustrate the theories, arguments and calculations. Part 2 consists of case studies on both financial and economic feasibility studies. Readers should be able to conduct their own financial and economic analyses by following the procedures and methodo-logy of the examples given.In this new edition, the chapters have been revised and expanded with the latest theories and data added, especially the most up-dated information on the development of the theories of internal rate of return and net present worth.
