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....
Instrumentation and Monitoring
A detailed plan for monitoring possible ground surface movements caused by the microtunneling operations should be prepared. The plan is typically prepared by the engineer in consultation...
Measurement and Payment
The owner shall establish a bid schedule to obtain pricing for all work associated with the microtunneling installation. This bid schedule provides the bidders the opportunity to establish...
Filling The Bay: Deepening the Oakland Inner and Outer Harbors
The project to deepen the Oakland Inner and Outer Harbors from elevation -42 to -50 ft was federally authorized in 1999 to accommodate the next generation of post-Panamax container ships....
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...
Notes on Heavy Lift Design
The interrelated activities and responsibilities of the various organizations involved in the lift design and offshore installation of topside facilities for an offshore platform are discussed....
The Joint Industry Development of a Recommended Practice for the Site Specific Assessment of Mobile Jackup Units
The mobile self-elevating (drilling) unit, or jack-up, has been central to the exploration and development of offshore oil and gas reserves. In recent years there has been an increased...
The Hail Problem
Unlike some other forms of precipitation, hail comes in bursts of short duration, falls over isolated and unpredictable locations, and usually occupies only a small percentage of the total...
The Design of Hail Suppression Operations
When hail suppression operations are being considered, it is already understood that hail damage is a significant problem in an area in which the political subdivision, organization, or...
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...
Evaluation of Hail Suppression Efforts
The rationale for conducting project evaluations is to find out how successful the operations are in achieving the desired results. This assessment is more easily said than done. It is...
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....
Sustainable Development � A Geotechnical Perspective
Sustainability has become a key factor in major construction projects these days, and many geotechnical engineers have started focusing on the concept. Owners, public agencies, and the...
Enhanced Detection and Mapping of Buried Utilities�A Sustainability Perspective
The social and environmental impacts and benefits of projects make up the triple bottom line that represents a modern view of sustainable project development. Rather than considering only...
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...
Condition Indices, Performance Measures, and Managing Performance Data for Geotechnical Asset Management � Don't Get Buried!
Why don't transportation agency assets like pavements, bridges, and earthwork have a Check Engine light? Why can't you simply pull up the complete history and life cycle plan for them?...
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...
Risk-based Methods for Geotechnical Features in Transportation Asset Management
The purpose of asset management is to meet life cycle performance goals through the management of assets in the most cost-effective manner. In developing risk-based, asset management plans...
