Pile Dynamic Analysis

Supplementing our geotechnical engineering expertise, TRC offers a unique set of skills that is fully capable of implementing the latest advancements in Pile Dynamic Analysis (PDA) testing. With 20 years of test methodology and test plan development experience, we can quickly interpret and implement a comprehensive and realistic PDA test sequence that fully meets a project’s requirements. Once deployed in the field, TRC staff quickly obtain the driving profile as a function of the depth penetrated versus the blow count. Our staff will then provide a summary of measured stresses, hammer efficiency and pile capacity. A final review of the measured pile parameters versus the predicted Wave Equation Analysis of Piles (WEAP) values is then performed for your field team so that fast and reliable

pile driving correlations can be determined in ‘real-time’. Once the field test data is obtained, it is modeled in CAPWAP to produce a comprehensive drive and measured stress summary that ensures pile integrity. Additionally, TRC offers preconstruction WEAP to satisfy your project’s pile driving needs. Through implementation of the WEAP analysis program, TRC staff can provide guidance and sound geotechnical predictions regarding the ‘drivability’ of your pile/hammer/soil system. We can also provide predictions of pile static compressive capacity using the DRIVEN program and lateral pile capacity using the L-Pile program.

About TRC A pioneer in groundbreaking scientific and engineering developments since the 1960s, TRC is a national engineering, consulting and construction management firm providing integrated services to the power, oil and gas, environmental and infrastructure markets. We serve a broad range of clients in government and industry, implementing complex projects from initial concept to operations. TRC delivers results that enable clients to achieve success in a complex and changing world. TRC includes over 4,000 technical professionals and support personnel in more than 120 offices throughout the U.S. Our clients depend on TRC’s multidisciplinary teams to design solutions to their toughest business challenges. TRC’s PDA Technicians continue to enrich themselves through by attending at specialty seminars that focus on the latest pile driving topics, and fully support a collaborative environment amongst their peers that keeps them informed of the latest data trends and geotechnical advancements in PDA testing. TRC is a certified user of the Pile Dynamic Analyzer (PAK model) and has passed the Foundation QA Institute’s Dynamic High Strain Testing Exam. TRC takes great pride in the fact that our PDA services start well before we arrive at the job site. We conduct a thorough review of each customer’s needs via our user-friendly online data gathering system which serves to promote the execution of a successful project. As a result of our proactive preplanning efforts and on-site operational experience, your project is allowed to efficiently move forward, thus enabling you to focus on other project demands.

TRC provided estimated pile uplift capacity based on CAPWAP analyses during the construction of US Coast Guard structures on the Delaware River between NJ and PA.

PDA testing was performed at night to accommodate acute project schedule demands for a project at the Lackawanna County Courthouse in Scranton, PA.
