Bridge Design Manual - LRFD.pdf
Taken from Implementation: Load and Resistance Factor Design (LRFD) is a design methodology that makes use of load and resistance factors based on the known variability of applied loads and material properties. In 1994, the American Association of State Highway and Transportation Officials (AASHTO) published the first AASHTO Load and Resistance Factor Bridge Design Specifications. The Federal Highway Administration (FHWA) has mandated the use of LRFD for all bridges for which the Texas Department of Transportation (TxDOT) initiates preliminary engineering after October 2007.
Hydraulic Design Manual.pdf
Taken from introduction: The hydraulic design or analysis of highway drainage facilities usually involves a general procedure that is essentially the same for each case. Some of the basic components inherent in the design or analysis of any highway drainage facility include data, surveys of existing characteristics, estimates of future characteristics, engineering design criteria, discharge estimates, structure requirements and constraints, and receiving facilities.
Time, expense, focus, and completeness of the design or analysis process should all be commensurate with the relative importance of the facility, that is, its cost, level of use, public safety, and similar factors. These aspects of the design process are often subjective. The funding or time constraints associated with any engineered project often are determining factors in the designer’s involvement.
Oil and Gas Production Handbook - An introduction to oil and gas production.pdf
Taken from Introduction: Oil has been used for lighting purposes for many thousand years. In areas where oil is found in shallow reservoirs, seeps of crude oil or gas may naturally develop, and some oil could simply be collected from seepage or tar ponds. Historically, we know of tales of eternal fires where oil and gas seeps would ignite and burn. One example 1000 B.C. is the site where the famous oracle of Delphi would be built, and 500 B.C. Chinese were using natural gas to boil water.
But it was not until 1859 that “Colonel” Edwin Drake drilled the first successful oil well, for the sole purpose of finding oil.
Engineering and Design Geodetic and Control Surveying (EM 1110-1-1004).pdf
This manual covers the use of engineering surveying techniques for establishing and/or extending project construction control. Accuracy requirements, standards, measurement procedures, calibrations, horizontal and vertical datum transformations, data reduction and adjustment methods, and engineering surveying techniques are outlined. The primary focus of this manual is on conventional (i.e., non-GPS) horizontal and vertical survey techniques using traditional ground survey instruments–transits, theodolites, levels, electronic total stations, etc. Typically, conventional survey techniques include traverse, triangulation, trilateration, and differential leveling.
Mechanical and Electrical Design of Pumping Station - Engineer’s Manual.pdf
The purpose of this engineer manual is to provide information and criteria pertinent to the design and selection of mechanical and electrical systems for flood-control pumping stations. Elements discussed include equipment requirements, design memorandum, Operation and Maintenance manuals, pumping equipment and conditions, discharge system, engines and gears, pump drive selection, pump and station hydraulic tests, earthquake considerations, power supply, motors, power distribution equipment, control equipment, station wiring, station and equipment grounding, surge protection, electrical equipment, environmental protection, station service electrical system, and station service diesel generator.
