Description of Workshop

As Collection Systems Professionals, we face a unique set of challenges on every conveyance project. Many of these are technical issues such as unique ground conditions, pipeline hydraulics, odor and corrosion concerns, and conflicts with existing infrastructure, while others require detailed coordination with outside stakeholders, such as permitting complexities, ROW and property issues, and community outreach. While there is no substitute for on the job training, there are lessons learned and tricks of the trade that can be applied to help your next project be successful. The purpose of this Pre-Conference Workshop is to provide a detailed overview of the proposal, design, bidding, and construction process as it relates to conveyance systems, including both gravity and pressure pipelines. The primary audience will be for engineers early in their career who would benefit from a primer on collection systems design, those engineers looking to get more into the conveyance field, or anyone who has interest in understanding more about collection systems design

A key component of this half day workshop will be to tackle a real-world example problem. We will intersperse discussion with presenters (conveyance designers, PMs, and O&M professionals) with group dialogue to evaluate an example problem. This will give attendees a more interactive experience and a chance to think through a design problem and what types of issues would need to be addressed. There will also be opportunities to discuss common pitfalls, lessons learned, and new technologies in the field of collection systems design.

Short Description of the intended audience

Geared towards those with less than 10 years’ experience, this half-day workshop provides an interactive overview of conveyance design, both technical and non-technical project complexities.

Learning Objectives

Attendees will learn about conveyance system design, focusing on both gravity and pressure pipeline applications. This will include a review of technical design issues, such as pipeline hydraulics, pipeline design, facility considerations (manholes, structures) and non-technical disciplines such as permitting, community engagement, and property issues.

Assessment

How will you assess that the participant has met the learning objectives? (Quizzes, successful completion of a lab exercise, Q&A session time?)

Q&A time will be built into the presentation to facilitate dialogue with attendees. The plan is to work through a project example with the group to demonstrate how design issues impact a project and let the attendees work directly with the presenters.

Outcome

Demonstrate the relationship between the learning assessment listed above and the expected learning outcome.

Attendees will be able to plan out a pipeline conveyance project, understanding the primary issues that can impact the design and construction of these facilities. They will know when to bring in additional expertise (geotechnical, permitting, environmental) and will identify potential pitfalls and issues that can impact their project. Attendees will also understand the basic design principals that go into a pipeline design, including hydraulics, pipeline materials, and construction techniques.

Who Should Attend

Engineers early in their careers, or those who are moving into pipeline design and would like to get a better understanding of the complexities associated with conveyance design.

Agenda

Follow the sample in the Workshop Guidelines document. Remember to include the mid-morning and/or mid-afternoon Networking Break of 15 minutes and the lunch (applicable only to all-day workshops).
