This standard guideline covers planning, design, pipe materials, and construction of microtunneling. The term microtunneling is defined as a trenchless construction method for installing...
Geotechnical IT Revolution: Intelligent Compaction and Beyond
The explosion of innovative developments in the IT industry is making many of us geotechnical engineers green with envy. We want some new technology, too! Luckily, advances in sensors...
ITS Then and Now
One of the authors of a 1992 strategic plan for developing intelligent transportation systems in the United States reviews the progress that has been made in the interim....
Lesssons Learned from Experience Dealing with Risks of Extreme Events: Part II
For every known IS vulnerability, there is a matching countermeasure. However, we do not know all IS vulnerabilities. The following tasks are geared towards identifying IS vulnerabilities,...
Role of ASCE in the Advancement of Computing in Civil Engineering
Computing has emerged as a major focus area in civil engineering, just as it has in other disciplines. This paper examines the role of the American Society of Civil Engineers (ASCE) in...
A Realistic Vision for the Future of IT in Civil Engineering and a Plan for Achieving It
In October 2001, a group of experts from the capital projects industry met in San Antonio, Texas to begin development of a comprehensive technology research and development (R&D)...
Multifaceted Trenchless Rehabilitation at the Middletown, Ohio WWTP
This paper describes the multiple trenchless technologies that were evaluated and the ones that were applied to the rehabilitation of a 78la diameter corrugated metal influent line and...
When To Sell
For owners of small firms, deciding to sell the business they've founded or owned can be gut-wrenching. But some owners find it's a good way to transfer ownership...
Socioeconomic Characteristics and Transportation in Berlin
Berlin's future as a site of commerce and services, as a significant goods handling center and as an important focus for commercial relationships, is dependent upon an intact transportation...
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...
Trenchless Transformation
The Framingham Extension Sewer (FES) was constructed of reinforced-concrete pipe in the mid-1950s as part of the wastewater collection system for the greater Boston area. Age and hydrogen...
The New Perspective on I.T.
In the last few years engineering firms have stopped seeing information technology as a support system and started looking at it as an opportunity to create new series. Through Web sites,...
Making Way for Water
The State Water Project Coastal Branch Aqueduct and Extensions brings 48,000 acre feet of water annually to 23 Southern California communities. built over five years, the project involved...
Riding the Technology Wave
Computer hardware and software is getting faster, more powerful and more affordable. At the same time, the way in which engineers use the equipment is varying. Identifying costs and benefits...
Sky High
The increasing demand for personal communication services (PCS), such as digital cell phones and pagers, as well as digital television (DTV), has created new challenges for creating and...
I.T.S. On the Way
With fewer roads being built, surface transportation engineers must develop ways to increase the efficiency of existing roadways by using intelligent transportation systems (ITS), but...
The Invisible Infrastructure
Most developed countries have 50- to 100-year-old underground utility systems that carry far greater loads than their designs. They're difficult to repair or replace, yet...
Wireless System
The technology of using radio frequencies to communicate is not new. Ham radio and walkie talkies were the first form of radio communication used by the public; then the Citizen Band (CB)...
Potential Flow Instability Theory and Bed Forms
An extended, generalised version of two-dimensional linearised potential flow theory of fully unsteady fluid flow-sediment bed interaction is presented. In contrast to previous potential...
