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...

Heave Compensated Landing System - A Novel Tool for Subsea Intervention
This paper presents a new intervention system that allows the use of a low cost workboat to deploy and recover delicate payloads in subsea installations. Vessel motions are decoupled from the subsea package...

Where Geosynthetics Meet Mining Geotechnics: Part of the Mining Engineer's Toolbox
From enhancing stability to providing environmental containment, geosynthetic materials play an important role in mining projects and geotechnics in general. While often overlooked, advancements in geosynthetic...

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,...

Self-Healing Concrete Uses Natural Stone Formation Processes

Fast Forward: Around the Bend
An architecture firm envisions an inverted U-shaped tower in New York City that would outstrip the height of current megatall structures and replace it with length....

When Old Meets New: Railway Geotechnics and Remote Sensing
Railroad track, like any other built structure, relies on a foundation of geomaterials for support. In its most basal form, the railway track is quite simple: steel load-bearing members (rails) supported...

Fast Forward: Towering Views
A proposed observation tower for New York City’s Central Park would comprise the world’s tallest temporary wooden structure and include a wind-powered system to filter water from the reservoir it would...

Restoring The Capitol Dome
While most construction projects serve only as local points of interest, some are conducted on a national stage. The restoration of the U.S. Capitol’s dome was one such project. The extent of the scaffolding...

Musical Masterpiece
La Seine Musicale, a world-class concert hall on a redeveloping island west of Paris, is a masterpiece of structural, acoustic, and mechanical engineering. Resembling a ship at sea, the concrete structure...

Rock Glue Gets the Job Done: Reducing Rockfall Hazards along the G.W. Parkway
After a large rockfall damaged the road and disrupted traffic along the George Washington Memorial Parkway in 2002, the National Park Service was looking for solutions to stabilize the slope against additional...

Borehole Geophysics: Tools to Characterize Rock Properties
Effective design and construction in rock requires characterization of the engineering properties of the rock mass, as well as any associated geological features such as joints, faults, and bedding planes....

Art by Design
The University of Iowa’s Visual Arts Building opened last fall on a campus that is still recovering from flooding in 2008 that caused nearly $800 million in damage. The structure houses the university’s...
