Access Granted
In southeastern Pennsylvania, CSX Transportation sought to increase the productivity of its Trenton Line freight rail service by improving the vertical clearance of its tracks so that it could operate...

Timber Rising
Ever-taller buildings made from engineered wood are being proposed and constructed around the world. To meet that demand, designers are being tasked with learning about the new capabilities, attributes,...

Fast Forward: One Small Step
A concept design for an inflatable habitat on Mars incorporates indigenous ice as a structural element and a shield to protect occupants from galactic cosmic radiation....

Engineer Wins First Round with Design/Builder, But the Fight Continues
A design/builder sued its engineer for inaccurate estimated quantities on a highway project. It’s a good reminder that designers working on projects should always read and understand their contracts....

Calibration of Jackup Leg Foundation Model Using Full-Scale Structural Measurements
The fitness of jack-up rigs to operate in varying water depths and weather conditions is determined by "site-specific" structural assessments. These assessments are conducted by a wide range of companies...

Design of Submarine Pipelines Against Upheaval Buckling
This paper describes part of a comprehensive joint-industry project on upheaval buckling. It develops a semi-empirical simplified design method and detailed design methods based on a new numerical analysis,...

Guidelines for Construction Vibrations: How Much Rattle is Too Much?
The study of construction/blast-related ground vibrations on structures, people, and objects is a surprisingly diverse field. Vibration sources vary from blasting, all types of construction equipment,...

Design for Major Flood-Control Project in Norfolk Begins to Take Shape

Testing the New Locks (part of "A Greater Wonder")
The recently completed third set of locks at the Panama Canal incorporates several civil components and hydraulic design features that are intended to reduce routine maintenance and conserve water. For...

Journal of Transportation Engineering, Part A: Systems
The Journal of Transportation Engineering, Part A: Systems contains technical and professional engineering articles on the planning, design, construction, operation, and maintenance of air, highway, rail,...

Journal of Transportation Engineering, Part B: Pavements
The Journal of Transportation Engineering, Part B: Pavements will contain technical and professional articles on the planning, design, construction, maintenance, and operation of airport, roadway and other...

D.C. Unveils Design for New Anacostia River Crossing

Translating the Language of Soils: Developing a Soil Classification System for International Engineering Projects
Soil classification systems are used to help predict soil behavior and provide information to farmers, engineers, builders, agricultural extension agents, homeowners, community planners, and government...

Optimized Drilled Shaft Design through Post-Grouting: Shorten That Shaft for Better Performance
Tip post-grouting is a technique used to inject, under pressure, a neat cement grout beneath the base of a drilled shaft. This method enhances or improves axial load-displacement performance by increasing...

Geotechnical Aspects of Pavements: There's More to Roads than Asphalt and Concrete!
When you jump on the highway to make that commute to work, do you think much about what's under the surface you ride on? Pavements are layered systems designed to provide a strong structure to support...

Foundation Reuse and Enhancement: A Viable Option for Bridge Widening and Replacement Projects
The transportation system in the U.S. includes over 607,000 bridges for grade separations, interchange configurations, and stream crossings. As governmental entities embark on the rehabilitation and rebuilding...

Answering the $64,000 Question: Geotechnical Risk in Design-Build Projects
Subsurface risk may well be the aspect of most construction projects that has the greatest potential impact on a project's success or failure. Even when a thorough geotechnical investigation is conducted...

What Does the Case Law Say? Geotechnical Risk on Design-Build Projects
The growth of design-build (DB) contracting, particularly on public-sector civil projects, has generated a great deal of industry discussion over the age-old question of who should bear the risk of unforeseen...

Geotechnical Delivery on Mega Transportation Projects: Challenges of Accelerated Delivery
Transportation projects have traditionally been delivered through the design-bid-build (DBB) delivery model, which continues to be the preferred method of delivering the majority of smaller and more traditional...
