Trump Administration Highlights Need for Infrastructure Spending, Permitting Reform
As part of a week dedicated to infrastructure, the Trump administration focused on aviation reform, increased federal funding, and efforts to reduce regulatory requirements for infrastructure projects....
Presidential Order Streamlines Permitting, Revokes Floodplain Requirements
An executive order issued by President Donald Trump to streamline the federal environmental review and authorization process for infrastructure projects prompts criticism for revoking Obama-era floodplain...
Small Projects are Big Deals
Geotechnical engineers work on a wide array of projects, ranging from small retaining walls or pavement projects, to construction of dams, canals, and foundations for bridges and high-rise...
Making Big Data Work for You and Your Project: A 3-D Geotechnical Model is a Smart Way to Work
Modeling the stratigraphy beneath a site and assigning soil and rock properties are important steps in geotechnical engineering. Geotechnical engineers often need to model ground conditions...
BIM in Geotechnics: The Benefits of Including Geotechnical Data in Building Information Modelling
Building Information Modelling (BIM) is becoming increasingly common around the world on building and civil engineering projects, but what are the benefits to geotechnical engineers and...
Introduction
The purpose of this white paper is to: foster understanding and transparency of analytical methods necessary to update and describe climate, including possible changes in the frequency...
Initial Criteria
Microtunneling is appropriate for a wide range of conditions. Careful evaluation of certain parameters will determine the applicability and constructability of a potential microtunneling...
Preliminary Geotechnical Considerations
In the planning phase of the project, a preliminary geotechnical investigation should be performed to identify the general subsurface conditions and any special subsurface conditions....
Project Layout
Microtunneling projects should be laid out with attention to the benefits and constraints unique to this construction process. The following recommendations address some of these concerns:...
Microtunneling Equipment
A discussion of microtunneling equipment in the context of the design aspects of a microtunneling project is applicable only to the extent that the engineer must set forth in the contract...
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...
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...
Contract Documents
As with any civil works project, the bid and contract documents prepared by the owner and the engineer should provide the contractor with the necessary information to prepare bids, to...
Field Aspects
As soon as practical after their arrival at the project site, all pipes, fittings, and appurtenances should be thoroughly checked for compliance with the contract documents and accepted...
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 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...
