Working Platforms for Foundation Construction and Related Equipment in the United States

Matt Meyer, P.Eng., D.GE, Principal at Langan Engineering & Environmental Services

Outline: As many of the Owners, General Contractors, Specialty Foundation Contractors and Engineers are aware, a working platform provides stability for cranes and drilling equipment required to install deep foundation systems or ground improvement/modification systems. The intent of this presentation is to provide an introductory type presentation of the topic, some background on US practices and approaches, a few examples of working platforms and to increase awareness that proper evaluation, design, preparation and maintenance of the working platform is critical to the safe operation of cranes and drilling equipment.

Mr. Meyer, in addition to his positions with the respective firm, Langan Engineering & Environmental Services, is a member of the Industry Wide Working Platform Working Group, which consists of various participants from ADSC, DFI and PDCA.

An Engineer’s Role in Mitigating Risk on Pile Driving Projects: An Operational and Legal Perspective

Alex Filotti, MBA, P.E., Risk Controller of Underpinning & Foundation, Skanska, Inc.

Rick Karlson, Partner, Benesch, Friedlander, Coplan & Aronoff LLP

Outline: The presentation will reveal the very important and complex role of the engineer in mitigating the risks of pile driving projects.

On the operational side the risk mitigation role, cover multiple aspects such as proper design, comprehensive geotechnical site exploration, optimum pile selection considering the supply availability and driving knowhow of the area contractors, safety by design, incorporation of contractor knowledge in the design, clear and simple driving criteria for the pile capacity and as build analysis.

On the legal perspective, the role of the engineer in risk mitigation is the writing of the project specifications, outlining of the scope of work, differing site conditions clause inclusion in the project specs, clear measurement and payment criteria, approving of the work, approving of change orders, etc.

Current Guidance and Code Issues Impacting Driven Pile Practice

Silas Nichols, P.E., Principal Geotechnical Engineer, Federal Highway Administration, Office of Bridges and Structures

Outline: One of the unintended consequences of recent code changes for highway geotechnics is that reliability and uncertainty in design methods and construction quality assurance procedures for driven pile foundations have evolved in complex ways. This has required agencies like FHWA to evaluate the intent and effectiveness of standards and codes to ensure that driven pile foundations are constructed safely, cost-effectively, and equitably with respect to other foundation alternatives. This presentation will cover some of the issues that FHWA is currently working on, and how they may impact future driven pile work.

Outline: Design/build has become a popular method of contract work delivery. It has many advantages over conventional design-bid-build methods, but also some disadvantages when it comes to foundations work. For driven piles, design/build contracts provide opportunities for the engineer and contractor to be innovative and responsive to findings on site, but also challenges due to the nature of the uncertainty inherit in the geotechnical condition’s information. This panel discussion provides the points of view from the various angles of involvement, and includes structural engineer, geotechnical engineer, pile driving contractor, and owner (FDOT).

A 2700ft Quay Wall Becomes an Engineering Challenge for Pioneers

Stefan Mewes, Dipl.-Ing (TU), Product Manager Pile Driving Equipment, Liebherr USA, Co.

Outline: Europe’s second largest seaport has installed a new combi-wall consisting of pipe piles, sheet piles and inclined shaft grouted piles to support it.
The Port of Antwerp’s location deep inland in Belgium provides more efficient transfer than most North Sea ports. Antwerp’s docks are connected to the hinterland by road and rail, as well as rivers and canals. As a result, the Port of Antwerp has become one of Europe’s largest seaports.

The new Liebherr piling rig type LRH 600 with swinging leader was used to drive shaft grouted piles into a very dense soil layer of sand with glauconite. The 195-foot Liebherr swinging leader was suspended at an inclination of 45° via a suspension frame and suspension ropes from the Liebherr crawler crane LR 1600, as carrier machine.

This inclined installation of shaft grouted piles via freely hanging swinging leader, as used for this project, is unique in Belgium. Moreover, the pile length of 140 feet is a novelty for this type of pile.
Shaft grouted piles or MV piles consist of a traditional steel profile with a separate box-like pile shoe with an open top. A separate injection pipe is welded to the flanges. The steel HEM pile is driven to depth using a free-fall hammer. A thin grout is injected via an injection pipe during driving and emerges just above the pile shoe. As the pile is driven further down so compressing the ground, the space above the pile foot is immediately filled with grout under pressure. This piling system is ideally suited for the transfer of high tensile loadings. It is a method to increase geotechnical load-bearing capacity and to reduce negative skin friction during pile driving.
Jan De Nul Group has successfully completed the pile installation and the project. Thanks to its multidisciplinary approach, the company was able to manage and execute this large-scale project within the scheduled time.

Pile Driving on the I-4 Ultimate Improvement Project

Michael W. Byerly, P.E., Florida Department of Transportation (FDOT), District 5 Geotechnical Materials Engineer

Carl W. Knott, P.E., HNTB Corporation, Foundation Engineer, Construction Oversight Services (COS), I-4 Ultimate Improvement Project

Outline: Presentation by Michael W. Byerly, P.E., FDOT District 5 Geotechnical Materials Engineer, and Carl W. Knott, P.E., COS Foundation Engineer, introducing the I-4 Ultimate Improvement Project – the $2.32 billion, Public Private Partnership (P3) that is transforming 21-miles of Central Florida’s most vital corridor. Topics of discussion will include project and geotechnical related information, pile driving activities and equipment, variability in subsurface conditions, and the utilization of soil-setup per the FDOT Specifications.
