Download or read book Management and Oversight of Structural Defects on Highway Bridges at the New York State Department of Transportation written by Thomas P. DiNapoli and published by DIANE Publishing. This book was released on 2010-11 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Between Jan. 1, 2006 and June 24, 2008, a total of 1,280 serious defects were identified on 228 State and 495 locally-owned highway bridges in New York State. To determine whether these defects were addressed within the required time frame of seven weeks, the report reviewed the records relating to a sample of 204 of the defects which pertain to 44 State and 74 locally owned bridges. It found that 69 of the 204 defects (33.8%) pertaining to 25 State and 16 locally owned bridges were not addressed within the required time frame. In fact, it took, on average, more than 17 weeks to address these 69 defects. This report contains 11 recommendations for strengthening the Dept.¿s oversight of the actions taken in addressing serious structural defects on bridges.

Download or read book Gravel Roads written by Ken Skorseth and published by . This book was released on 2000 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

Download or read book Lifetime Modeling of Deficient Bridges in New York written by Levi Phippen and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Given the importance of bridges to a state's economy and strength, and the costs involved in building and maintaining bridges, maximizing their service life is essential. In order to safely extend a bridge's utility as long as possible, an understanding of its lifetime processes is needed. This paper attempts to model the lifetime of a bridge in New York once it has become deficient. Lifetime is defined to be the length of time between deficiency classification and failure. A bridge is considered deficient when certain structural components receive a poor rating in the National Bridge Inventory, which is compiled annually by the Federal Highway Administration. A list of bridge failures is provided by the New York State Department of Transportation. In 2012 the Federal Highway Administration database showed that 39.5 percent of New York's bridges were deficient. Using analysis of variance and considering a bridge failure to be a random Bernoulli trial, this paper shows that New York's deficient bridges are typically older than their non-deficient counterparts, and that they are also more susceptible to failure. From survival analysis techniques an estimate of the mean time to failure of a deficient bridge is found to be 47.2 years. Finally, a statistical model is created to predict the lifetime of a deficient bridge, while accounting for influential factors such as average daily truck traffic, deck geometry and structural evaluation ratings.

Book excerpt: There are approximately 2,100 bridges in the Metropolitan area of New York City; 842 of the bridges, counting over 4,500 spans, are the responsibility of the City administration. According to New York State inspection records, 56% of these bridges are rated less than 4.5 on a 7 grade system. This is regarded by the New York City Department of Transportation (NYC DOT) Bridge Bureau as an indication of the need for structural repair of some magnitude. In the situation involving 42% of the City's bridges, a ten-year,
