Dewatering Lunch and Learn – presented by Griffin DewateringAdd to Calendar
Please join us in Seattle for this informative Lunch and Learn on construction dewatering.
Lunch will be ready at 11:30 a.m., followed by the presentation.
This non-commercial seminar lasts approximately one hour, including lunch and a training certificate for all attendees. Participants will leave with a basic understanding of the following dewatering fundamentals:
Construction Dewatering 101
Dewatering means the removal of water from soil or taking the water out of the particular construction problem completely. In other words, we are discussing the pre-drainage of soils and/or groundwater control at construction sites. Construction sites can range in size and complexity from a simple man-hole replacement on a sewer line to a multi-block urban development project. Additionally, dewatering may be required at environmental-remediation sites, including coal ash (CCR) and manufactured gas plant (MGP) remediation.
The presentation will cover the following topics:
• What is dewatering and why is it needed for construction activities
• Site/project specific data required to develop a dewatering plan
• Drawdown, cone of influence and hydraulic conductivity basics
• Types of dewatering systems
• Drilling equipment
• Water treatment
• Case studies options include
- Coal ash dewatering
- Basic construction dewatering
- Levees and dams
- Water treatment
The data presented will be useful for both seasoned and relatively new construction professionals. This program is an informal format, and attendees will be encouraged to engage in the discussion.
Presenter: David Bardsley
David Bardsley, PG, has over thirty-eight years of geotechnical, water-supply and environmental drilling experience working in a variety of settings across the United States. He started his career as a drillrig helper, advancing through various technical and managerial positions in both small and large drilling companies. He was an early leader in the use of horizontal directional drilling and well-installation methods to solve environmental and water-supply challenges. Mr. Bardsley has recently transitioned back into the traditional vertical drilling and well-installation market with Griffin Dewatering.
Mr. Bardsley has a B.S. in Geology & Geophysics along with a Communications minor (1984) from the University of Missouri-Rolla. He is a licensed well driller in Texas, Arizona and Louisiana and holds RG/PG certifications in Texas, Missouri, Louisiana and Tennessee.
