Detailed Site Investigations
This section addresses site investigation issues that are important for detailed design and construction of microtunneling projects. These site investigations include the following: Geotechnical...

Microtunneling Design Elements
The design elements and the process for a microtunneling project are generally the same as for other underground projects. Design elements include the following: General conditions; Special...

Microtunneling Operation
The shaft should provide safe working conditions and fully support the ground. Jacking and receiving shaft support system and sizes are typically determined by the contractor. See Chapter...

Shafts/Temporary Structures
Shafts should be of a size to accommodate the equipment and pipe selected and to allow for safe working practices. If the shaft must accommodate the permanent works, it is the contractor's...

Construction Support Services
A preconstruction survey of existing structures within the anticipated construction zone of influence should be conducted before any construction begins. A plan for structures that need...

Regulations
The contractor should meet federal, state, and local regulations. The contractor is responsible for jobsite safety....

Innovative Use of a Groin Structure: Saving Cost, Shortening the Schedule, and Minimizing Impacts
Almost any type of construction activity can pose a shock to the surrounding environment and habitat. Obviously, the extent of the impact will depend on the location of the project and...

The New Bedford Marine Commerce Terminal
When construction of the first American offshore wind farm support terminal encountered greater challenges than expected, jet grouting enabled construction to continue....

Performance Limits for Deepwater Pipelines
This paper highlights the differences between onshore and offshore pipeline design. It then summarizes the results of combined external pressure, tension, and bending testing on full scale...

Conduct of Operational Hail Suppression Projects
Those conducting hail suppression operations should be vigilant and always prepared to react when potential hailstorms begin to develop. In this chapter, some guidance is provided for...

Failure of a Twenty-Foot High Retaining Wall
A cantilever retaining wall, designed in apparent accord with provisions in a civil engineering handbook, failed soon after construction. Analyses of the causes of the failure are presented....

Advanced Fracture Control Procedures for Deepwater Platforms and Compliant Towers
This paper describes an integrated approach to fracture control problems – applied first as a necessary adjunct to the authors' own engineering practice, then in developing...

Offshore Platform Steel Specification
The discovery in the 1980's of local brittle zones (LBZ's) in and near the heat-affected zone (HAZ) of the fabrication welds in certain offshore platform steels...

Geo-Shanghai 2014
Proceedings of the Geo-Shanghai 2014 International Conference, held in Shanghai, China, May 26-28, 2014. Sponsored by the Geo-Institute of ASCE. These...

Managing Geotechnical Assets to Improve Highway System Performance
As geoprofessionals, we have a great opportunity to look at our work in new ways and to show its value to others. Highway agencies are looking to get the most from their assets and with...

Multi-scale Health Assessment for Effective Levee Management
Researchers are working on developing a new health assessment framework with the potential to modernize our ability to monitor, manage, and ensure the safety of levees and other systems...

Asset Management of Earth Retaining Structures: Design through Design Life
Regarding new earth retaining structures (ERS) construction, the message is clear: plan for asset management. New construction is certainly not immune to performance issues, and the time...
