Wireless Warnings
Formwork failures cause dozens of construction-related deaths per year, but most can be avoided by adequate monitoring. The problem is, most monitors must be hard-wired to a computer on...
Taking a New Approach (available in Structural Engineering Special Section only)
The first bridge rehabilitation project in Washington, DC to use the AASHTO Load and Resistant Factor Design (LRFD) specification reveals several lessons to be learned from using the newly...
Sinking a Sewer Line
The design and construction of a sanitary sewer siphon using high density polyethylene (HDPE) pipe in San Juan, Puerto Rico, provided Black & Veatch with a challenging opportunity...

Communicating in a Crisis
As professionals following the strictest ethical standards, civil engineers are entrusted with safety and well-being of the public, regardless of the scale or range of their designs. By...
Blocking the Tide
The city of Venice is in peril as a result of increased tidal flooding, and a proposed system of movable gates offers the greatest promise of safeguarding the city's future....
Examining the Capitol Dome
The dome of the United States Capitol, designed and built from the 1850s to the 1860s, is a masterpiece of 19th-century engineering and construction. The majority of the dome is made of...
Design Live Loads for Parking Garages
The objective of this research project is to obtain a better understanding of parking garage live loads and to recommend an appropriate value for design. A load survey was conducted in...
Foundation Design for the Elevated Station
The Amundsen-Scott South Pole Station is located at an elevation of 2,850 m on the 3,200 m thick polar plateau, a field of ice and snow that is moving toward the ocean at a rate of 10...
Irrigation Method Selection Process
Intelligent selection of the irrigation method that best meets the goals and objectives of an irrigated agricultural development is of primary importance in the design process. A system...
Weighing Anchors
Modern anchorage systems offer design engineers and contractors unprecedented choice in load transfer mechanisms. Some anchors are highly specialized, while others are appropriate for...
Bridging Substance with Style
Engineers used an elegant form to come up with a functional solution when designing the new Damen Avenue Arch in Chicago. Two steel ribs, created using heat induction bending, closely...
Structural Surgery
Structural engineers had to transform four existing buildings and two new buildings into a new non-profit center for Jewish history. The buildings were of varying ages and had different...

Power Struggle
The Florida Light and Power Company could have replaced its deteriorating, H-shaped wooden power poles in the Tomoka River with exact duplicates, but they chose to use hybrid steel-and-concrete...
Roughness Coefficients in Manning's Equation as an Estimating Tool for Bankfull Discharge in Natural Channels
(No paper) This paper compares the results of Annable's work to the roughness coefficients by stream type given in Rosgen (1994) as well as some additional coefficients from the eastern...
Stepwise Flood Routing for Gated Reservoirs and Conjunctive Optimization of Hydroelectricity Income with Flood Losses
A six-stage operation policy for routing of flood hydrographs of return periods from 1.01 year up to the Probable Maximum Flood (PMF) for dams having gated spillways is suggested. The...
Dynamic Groundwater Remediation Design with Genetic Algorithms
In groundwater remediation design it has been shown that dynamic policies, in which the pumping strategies may vary throughout the remediation period, can result in more cost-effective...
Simplification of Detailed Models of Water Distribution Systems Obtained from GIS Systems
For a long time simplified models have been used to simulate the behaviour of large water distribution networks. Often, simplification has been carried out by removing small diameter pipes...
Friction Factor Choice in Hydraulic Simulation Models: Does It Matter?
(no paper) To model water distribution systems using computer hydraulic simulation, a user is required to select a form of head loss-flow relationship for each pipe in the network. The...
