The AASHTO LRFD Bridge Design Specifications allows the use of either of two design methods for precast reinforced concrete pipe; the indirect design method or the direct design method. The indirect design method relates the strength of the pipe in the field condition to its three-edge bearing strength tested at the plant. The majority of reinforced concrete pipe designs are performed with the indirect design method, resulting in one of five pipe classes or a specified D-Load. The indirect design method is one of the most complete design methods used for buried drainage pipes, while also being one of the quickest to perform. Join this webinar to learn how to design RCP with the indirect design method.

The basic Indirect Design Method used for precast concrete pipe is relatively simple. However, to save time, the American Concrete Pipe Association (ACPA), along with the Canadian Concrete Pipe and Precast Association (CCPPA), have made available a web-based program called PipePac. PipePac has three modules:  Life Cycle Analysis (LCA for evaluating the life cycle cost of a pipe installation, CAPE (Cost Analysis Pipe Envelope) to evaluate the installed cost of various pipe products, and the 3 Edge Bearing (3EB) Analysis to perform an indirect design of buried precast concrete pipe.

This seminar will focus strictly on the 3EB Analysis module of the program and is a follow up webinar to Basic Concrete Pipe Design.  Knowing the basic nomenclature used for Indirect Design, the Engineer can easily perform designs using PipePac/3EB.  This webinar will take the software user through the program and design examples.

This presentation introduces and reviews of AASHTO R-73, which provides excellent guidance on the evaluation of Pre-installed precast concrete pipe, box culverts, manholes and drainage inlets.  R-73 describes criteria for acceptance, repairable and rejection criteria of precast products. Examples of acceptable and rejectable precast products will be shared in this presentation. Intended for inspectors in the field and at the manufacturing facility.  This guide is not intended for the evaluation of installed precast concrete pipe, box culverts, three-sided structures, manholes, drainage inlets or other precast products.

Buried pipelines are a long-term investment and their effective service life can be ensured with quality installations. With limited budgets for regular onsite soil testing and construction observation, one of the best ways to verify satisfactory pipeline installation is through post-installation inspection (PII). PII provides value and confidence to engineers, owners, and the traveling public that underground infrastructure will meet the intended service life, similar to a home inspection prior to a real estate purchase. With how much is being invested in infrastructure, it’s important to use PII to protect these investments.  This course will overview common post-installation inspection methods, categories of possible defects to watch for, and applicable standards for evaluation criteria.

In the United States more than 800 construction workers die every year while on the job. One of the most dangerous types of work is trenching, which kills 40 construction workers every year. The Occupational Safety and Health Administration’s (OSHA) Excavation standards, 29 Code of Federal Regulations (CFR) Part 1926, Subpart P, contain requirements for excavation and trenching operations. This training highlights key elements of the standards and describes safe work practices that can protect workers from cave-ins and other hazards.

Building safer and more resilient communities comes in a variety of ways, from product, to design, to installation. This webinar will focus on how adhering to DOT installation standards for concrete pipe will increase the longevity and value of infrastructure by reducing potential failures and decreasing maintenance costs.

The course will cover basic concrete mix designs and batching, box culvert reinforcing and manufacturing methods, pipe reinforcing and manufacturing methods, and will wrap up with a discussion on curing.

Understanding the history and the basic and unique attributes of concrete pipe will give you a better understanding of where we are headed in the future. This presentation hits upon understanding the design, strength, installation, performance, and true value of concrete pipe. Attendees will have the chance to see a life cycle analysis of drainage systems and better understand the connection between the sustainability and the resilience of concrete pipe. Whether you know a little or a lot about concrete pipe, you will find this presentation informative!

Asset Management provides agencies/owners both a long-term roadmap toward better supervision of asset inventories, as well as data necessary for logical material placement and usage. This information allows agencies to make sound engineering decisions backed by years of data, which in turn improves resilience of the infrastructure system and maximizes sustainability.

In this webinar, we look at current issues and actions that impact such decisions in critical locations such as evacuation routes, flood prone areas, emergency access routes, and others. We also explore how asset management data can be used to help prepare for recovery from major natural disasters, and to determine the most appropriate mitigation planning.
