The Federal Highway Administration (FHWA), in collaboration with industry partners, is helping state DOTs take their existing geotechnical site characterization programs to the next level. Technologies...
Practical Aspects Of Routine Geotechnical Site Investigations � They Should Be Anything But Boring!
It�s likely that on any given day there are hundreds of geotechnical site investigations in progress in North America alone. While many of these investigations are carried out in support of large projects,...
Pay Now, Or Pay Later � Using A Risk-Informed Mindset for Site Investigation Decisions
How much subsurface investigation is adequate to aid in the planning and design of a construction project? It�s a question every geo-professional must grapple with, particularly in an era where cost efficiency...
Site Constraints Complicate a Bulkhead Replacement: It Takes a Team to Overcome the Challenges
North American Aggregates (NAA), a leading supplier of aggregates in the New York area, recently constructed a new processing facility in Perth Amboy, NJ. One of the final components of the new facility...
Beyond the Water�s Edge: Geotechnics in the Wet
Gaining insight into the subsurface and developing an understanding of what�s hidden below ground is a key to the design and construction process. Geotechnical engineers and geologists often develop their...
Subsurface Utility Engineering and Megaprojects: Avoiding Underground Conflicts Helps Speed Project Delivery
Experienced project owners realize that utility conflicts can be risky and pose unexpected impacts on the cost and delivery of projects, especially in urban settings. To help overcome these impacts, Subsurface...
Senate Subcommittee Examines Risks to Superfund Sites from Natural Disasters
In the aftermath of recent natural disasters, a Senate subcommittee examines how to improve the protection of Superfund sites against such events....
A Light in the Deep: The Future of Offshore Site Investigations
For deep-water energy developments, hazard identification and risk assessments (that is, assessing the probability of occurrence along with the consequences of failure) are more important...
Long-Term Performance Monitoring of a Hillside Retaining Wall
To accommodate expansion of the West Point Treatment Plant in Seattle, WA, a 3,000-ft-long soldier pile, tieback-anchored retaining wall was constructed from May 1991 to May 1992. An oblique...
Achieving Success and Avoiding Failures with Permeable Pavements
This chapter provides experienced-based recommendations on how to achieve success with permeable pavements. This information is based on an informational survey completed by designers,...
Maintenance
While site selection and proper construction are the most critical factors in establishing that permeable pavements function as designed, all must be inspected and maintained to maximize...
Site Conditions
The owner and the engineer should visit the proposed site during the initial planning phase and periodically throughout design to identify site conditions and constraints. A survey of...
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...
Shaft Considerations
Jacking and receiving shaft locations should be selected to minimize the number of shafts and disruptions while not exceeding the practical limits of the drive lengths achievable for a...
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...
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...
Restoration and Cleanup
The contractor should be responsible for site restoration and keeping the construction site clean, neat, and orderly at all times....
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...
Underpinning and Shoring of the Historic Howard Theatre in Washington, DC
The Howard Theatre was constructed in 1910 at 620 T Street, NW in Washington, DC. In 2010, a group of sponsoring organizations and developers put together a $17.1 million plan to revitalize...
