Innovative Technologies in Bridge Construction
PDCA Associate Member Highlight

The final installment of the PDCA 2021 Education Webinar Series will focus on highlighting various PDCA Associate Members. Five associate members will discuss their products, innovations, technologies, and more related to Bridge Construction and challenges engineers may face and how to overcome them. 

PRESENTATION information
  • Large Driven Bridge Piles - Lightweight Equipment 
    • Teemu Riihimäki, Junttan
    • Summary: The presentation will give an overview of bridge construction examples where access and working platforms were very difficult to achieve, but through the planning of lightweight dedicated rigs, advanced testing methods, Junttan and its customers were able to achieve rather large diameter pile driving and pile capacity with lighter weight equipment and hammers.
  • Bridge Construction with the Press-in Piling Method
    • Ian Vaz, Assistant Manager of Business Development, Giken America Corp.
    • Summary: This presentation will discuss how the press-in piling method was utilized for its non-vibratory, highly accurate, and speedy installation of steel sheet and pipe piles within low headroom on three challenging bridge projects. While the presentation will go into why the press-in piling method was selected for one construction project to install pipe piles almost 200ft below the ground surface, the discussion will continue with two other emergency construction projects that were carried out to stop severe scour from causing potential secondary disasters.
  • Accelerated Construction with Sheet Pile Bridge Abutments 
    • Ric Anderson, P.E., S.E., Nucor Skyline
    • Summary: Steel sheet pile bridge abutments are an innovative solution which provides savings in time and cost on many types of bridge projects. The basic concept of this solution is that the sheet piles can provide both the temporary formwork for the construction of the bridge, as well as the final abutment face and piling support for the bridge deck.
  • Best Practices in Pile Driving Testing Utilizing the PDA and GRLWEAP14 
    • Ryan Allin, P.E., Vice President, Pile Dynamics, Inc.
    • Summary: GRLWEAP, a wave equation analysis program, is used with the Pile Driving Analyzer® (PDA) to simulate motions and forces in a foundation pile when driven by an impact or vibratory hammer. Developed in the 1970s, GRLWEAP has been improved continuously to help increase the accuracy of predicted stresses, bearing capacities, blow counts and installation time. Newly released, GRLWEAP14 features static geotechnical analysis tools including methods based on soil type, SPT or CPT information and the American Petroleum Institute (API) method, as well as Residual Stress Analysis, and variable toe area input for consideration of plugging in selected soil layers, and more. The Pile Driving Analyzer® (PDA) is a reliable and cost-effective QA product that can accommodate a wide variety of subsurface conditions, as well as eliminate the guesswork in foundation design. High Strain Dynamic Load Tests, also called PDA tests, assess the capacity of several piles in a single day. PDA systems evaluate shaft integrity, driving stresses, and hammer energy when monitoring installation. PDA tests are performed during driving on pilot or production piles, taking advantage of the high strain impact provided by the driving hammer. Re-strike PDA tests are often recommended; if the driving hammer is no longer on location, a drop weight may be used to impact the pile. The PDA takes data obtained by accelerometers and strain transducers easily attached to the pile and calculates foundation capacity.
  • American - The Right Way
    • Mark Gwynn, American Spiral Weld Pipe
    • Summary: The presentation will give a brief company history, the manufacturing process of Spiral Weld Pipe, and how they go to market.
Upon completion of the webinar program, you will be eligible to receive up to 1.5 Professional Development Hours (PDH). This is based on the length of time you attend the webinar and is recorded through the Zoom platform. PDCA staff will automatically calculate the hours for each attendee and send certificates accordingly.
