2019 Spring Conference

2019 Fall Conference

The Louisiana Parish Engineers and Supervisors Association (LPESA) was founded in 1972 to foster and maintain a high professional spirit among Louisiana parish's public works and engineering employees. It provides instructive, entertaining, and important programs to those primarily concerned with the planning, operation, and maintenance of parish infrastructure. The LPESA is an organization through which programs may be coordinated among parishes and other government agencies. The organization's goal is to include an active member in every parish in Louisiana. CLICK HERE to visit the LPESA website.

LPESA Virtual Showcase logo

LPESA Virtual Showcase is designed to provide professional development and networking opportunities for the LPESA members, associate members and partner organizations. Each month, we bring in a subject matter expert to share valuable information on relevant program(s), product(s), tools(s) and/or service(s) that may be of interest to the LPESA group and local communities across Louisiana. Topics include, but not limited to, public works, emergency preparedness, road safety, worker safety, road maintenance, construction, pavement preservation, railroad safety, local bridges, and more. Participants will receive 1 PDH for each session attended.

Survey Lite Using Mobile LiDAR and Panorama Videography: Preparing Accurate Strip Maps for AutoCAD, DGN, and ESRI
April 16, 2021
10:00 a.m. - 11:00 a.m. (CST)

Presenter: Wilfred Barry, SJB Group, LLC
The SJB Group will demonstrate a surveying application using Mobile LiDAR and panorama videography with GPS observations in State Plane Coordinates. The end product is an array of strip maps of highway or/or utility rights-of-way surface features. These features are then digitized and drawn in 3D and can be provided in AutoCAD, DGN, or ESRI shape files. SJB Group calls this Survey Lite and costs a fraction of full blown conventional surveying. The accuracies are good for preliminary concepts and designs. Full surveying can then be concentrated on areas that need it, not the whole highway/utility corridor.

Louisiana DOTD’s Specification for Internally Cured Concrete: The Key to 100-Year Service Life?
May 21, 2021
10:00 a.m. - 11:00 a.m. (CST)

Presenter: Jeff Speck, FACI, Arcosa Lightweight
Internal curing using presoaked lightweight fine aggregate reduces concrete shrinkage and related cracking, extending the service life of structures built with Internally Cured Concrete (ICC). Lafayette Consolidated Government has led implementation of ICC in Louisiana with the help of the Louisiana Transportation Research Center (LTRC). LA DOTD has drafted a new specification for ICC for use in the state’s transportation structures to maximize the return on its infrastructure investments.

Arcosa Lightweight, in support by the Concrete and Aggregates Association of Louisiana (CAAL), will present the science behind ICC, review the draft DOTD specification and provide examples of the use of ICC in Louisiana and throughout the U.S.
