Case Study of an Offshore Horizontal Boring
A pipeline system was needed to transport natural gas from a discovery in Mobile Block 823 to Mobil's existing system inside Mobile Bay. Sand Island, a small barrier island off Dauphin...
Dutch Experience on Design of Dikes and Revetments
The increased demand for reliable design methods for protecting structures has resulted in The Netherlands in preparing a set of design guidelines for design of dikes and revetments. The...
Development of Detached Breakwater Design Criteria Using a Shoreline Response Model
An evaluation of beach response to detached breakwaters was conducted using the numerical shoreline response model GENESIS. Functional design parameters such as structure length, gap distance,...
Application of a Dolos Structural Design Procedure
Dolos concrete armor units are widely used to protect coastal structures. New developments in armor unit strength design permit the armor unit designer to optimize the dolos parameters...
Concrete for Sealing Voids in Rubble Structures
Permeability of rubble-mound breakwaters and jetties to sand transport and wave transmission results in increased costs for dredging and navigation. Guidance is provided for economically...
Application of Extremely Low Altitude Photogrammetry for Monitoring Coastal Structures
Extremely low altitude mapping photography exposed from a helicopter is showing considerable promise in providing another method of extending the many benefits of photogrammetric data...
Value Engineering in Coastal Design
A formal procedure of value engineering can be applied to coastal design to refine a design and reduce the construction costs. Despite the relatively simple technology and materials used...
Environmental Effects of Beaufort Sea Causeways
Two gravel-fill causeways have been constructed into the shallow nearshore Beaufort sea on the north coast of Alaska for the development of petroleum reservoirs. These long (4-8 km) structures...
Sandbridge Virginia Oceanfront Seawall Arbitration Hearing: Some Lessons Learned for Coastal Engineers
A group of beach property homeowners claimed that their new oceanfront seawall was defective in design. A beefed-up design cost about $1.3 million more and they sought this amount from...
Retrofitting a Landmark
A decade after it was abandoned, a famous sixty year old tire factory has been rehabilitated as part of a $118 million adaptive mixed-reuse commercial-office mall known as the Citadel....
A Case of the Shakes
New York City's unusual Terrace on the Park offers dining and dancing in a catered ballroom that stands six stories above the ground on four supercolumns. But when guests...
Seismically Safe, Spectator-Friendly
As 50,000 frightened spectators at Candlestick Park can attest, the Loma Prieta earthquake in 1989 provided chilling evidence of the importance of seismic design in public structures....
Peaches and Concrete
One Peachtree Center, Atlanta's latest highrise tower, will measure 62 stories high (860 ft) with 1.42 million sq ft of office space when completed next July. It will also...
L'Ambiance Plaza: What Have We Learned
In April 1987, a structure called L'Ambiance Plaza collapsed during construction, killing 28 workers. The building, in Bridgeport, Conn., was being built using the lift-slab...
Engineering a Monument, Evoking a Nightmare
Rather than simply standing as a backdrop for exhibits, the $53.2 million U.S. Holocaust Memorial Museum is intended to be part of the fabric of the exhibition itself. Now under construction...
Real-Time Condition Monitoring of Concrete Structures by Embedded Optical Fibers
Fiber optic sensor methodology has matured to the point where the impact of this new technology is now evident, especially in aeronautics and space structure applications. External perturbations...
Concrete Beam Testing with Optical Fiber Sensors
The use of an embedded multimode optical fiber to monitor curing and load-to-failure testing of a reinforced concrete beam has been investigated. The embedding process used to network...
