This guide presents the proper procedures for the design, fabrication, inspection, testing, and installation of concrete poles. It outlines the information that a line designer should provide to the engineer who is designing the pole structure. It also suggests a suitable quality assurance program to ensure receipt of adequately designed and manufactured product. The guide addresses concrete poles that are spun or statically cast and that are prestressed, partially prestressed, or conventionally reinforced. This performance-oriented guide presents theories and methods that are generally recognized as good practice, but also allows for innovative and unique circumstances to be fully acceptable upon presentation of sufficient test data to demonstrate that proper performance can be achieved.
Design and Construction of Urban Stormwater Management Systems presents a comprehensive examination of the issues involved in engineering urban stormwater systems. This Manual?which updates relevant portions of Design and Construction of Sanitary and Storm Sewers, MOP 37?reflects the many changes taking place in the field, such as the use of microcomputers and the need to control the quality of runoff as well as the quantity. Chapters are prepared by authors with experience and expertise in the particular subject area. The Manual aids the practicing engineer by presenting a brief summary of currently accepted procedures relating to the following areas:financial services; regulations;Ø surveys and investigations;Ø design concepts and master planning;Ø hydrology and water quality;Ø storm drainage hydraulics; andØ computer modeling.
This report investigates whether standards or guides are useful to hydraulic engineers and whether additional standards or guides should be prepared. The results of a questionnaire indicate that most hydraulic engineers are not familiar with the procedures used to develop standards or with existing national or international standards. However, responses to the questionnaire show that hydraulic engineers welcome guides or standards as long as some flexibility to use engineering judgment for site specific conditions is allowed.
The report recommends that guidelines or consensus standards be developed in the following areas:application of one-dimensional surface water computer programs of the HEC-2 type; prediction of scour at bridge piers; design of pump intakes and sumps; and calculations of friction and form losses in closed conduits.
Annotated lists of standards and guidelines produced in the United States and abroad are included.
