Southeast Water Treatment Plant

■Average daily pumpage is approximately 35 MGD or about 24,300 GPM (Gallons per Minute)

■Maximum day pumpage was 75 million gallons

■Total storage capacity – 52 MGD

■Over 1,000 miles of water mains


Project Background

■ Current construction project began Spring 2015

■ New 24 MGD raw water intake on Lake Guntersville just upstream of Guntersville Dam

■ Approximately 3 miles of 42-inch DIP raw water main to plant

■ New 24 MGD conventional water treatment plant at the intersection of Highway 431 and TVA Guntersville Dam RD

■ Flocculation/Sedimentation/Dual Media Filtration/Granular Activated Carbon Filtration/Chlorination

■ Approximately 8 miles of 48-inch DIP finished water main from plant to existing distribution system

■ Expected construction completion Summer 2017



Design


Journey from 2D to 3D

■Why move into 3D?

■Choosing a 3D modeling software

■What hurdles to overcome?

■Benefits to working in 3D


Why Move to 3D?

■ Industry future

■Superior product

■Coordination

■Efficiency

■Accuracy


Which 3D Modeling Program to Use?

■Client requirements?

■Do we have disciplines or design centers already working in 3D?

■Compatibility issues

■Out-of-the-box library of content

■Ease of use and training available


Challenges to Overcome

■Learning and teaching the new program

■Create project workflows

■Creating existing company CAD standards in Revit format

■Create cohesive plan set

■Create custom content library


Benefits to 3D Modeling

■Accurate quantities and estimates

■Smart labeling and schedules



■Phasing capabilities

■Photorealistic renderings



■Easily add 3D “perspective” views to the construction planset
