City of Phoenix 24th Street Water Treatment Plant
Phoenix, Arizona, United States
To control the formation of disinfection by-products in a potable water distribution
system, the city of Phoenix, Ariz., implemented an innovative 3D design for a $65
million, 120 mgd granular activated carbon post-filter contactor facility. Efficient
interaction bet ween the city and contractor using 3D models visualized the intricate
design, accommodated plant operator needs, and minimized and resolved conflicts
between various elements within the contactor pipe gallery.
Weekly team meetings – using Project Wise to share files and submit drawings
– facilitated coordination among the prime consultant and two major
subconsultants. The enhanced design process using MicroStation, PlantSpace, and
STAAD.Pro allowed the city to improve water quality for customers within budget
while making the project up to 25 percent more profitable for the contractor.
denver Metro Wastewater Reclamation district
Denver, Colorado, United States
The Metro Wastewater Reclamation District in Denver, Colo., serves
approximately 1. 5 million people and operates the Robert W. Hite Treatment
Facility, which includes two complexes for sludge removal. Metro selected
Carollo Engineers to provide $17 million of design services for expansion of its
South Secondary Improvements Project. The goal was to create capacity to
handle flows of over 200 million gallons of wastewater per day and meet more
stringent future discharge criteria.
Carollo used MicroStation, Bentley Structural, Bentley Architectural,
PlantSpace, InRoads, Project Wise, Bentley Navigator, S TAAD.Pro, and RAM for
Structural Analysis to develop a design incorporating many novel engineering
features as well as communicate the project vision and layouts to all
stakeholders. Design engineers had real-time access through Bentley Navigator
to evaluate potential layouts, coordinate with other disciplines, minimize
conflicts, and maintain efficiency.
