Design-Build-Operate: Recommended Best Practices

Posted by Admin on Thu, Jul 02, 2015 @ 10:25 AM

Design-build-operate (DBO) offers an important expansion of the design-build (DB) project-delivery method for the water and waste-water industry. DBO comprises all of the components of DB -- including design, permitting, procurement, construction, and testing -- and also includes operation and maintenance (O&M) of the completed facility. Thus, the delivery of the project and services provided to the owner do not end at final acceptance; services continue through a defined operational term.

Progressive Design-Build Delivery Retrofits a Water Treatment Plant

Posted by Admin on Fri, Jun 12, 2015 @ 10:31 AM

In 2013, the city of Venice, Florida needed to retrofit its existing Reverse Osmosis (RO) 4.4 mgd, water treatment plant with new RO membrane skids that could meet the existing total dissolved solids (TDS) and flow conditions. To accomplish this task, the plant also needed to have the flexibility to decrease well withdrawals by second stage treatment and increase capacity without increasing well withdrawals through increased recovery.

As a result, the city’s overall goal for the project was to optimize the existing (treatment) system for the future and get the best performance out of the membranes by installing new pumps, cartridge filters, upgrading the clean-in-place system; and providing a new state-of-the-art fully automated SCADA system.

Using Design-Build to Improve the Water System in Goodyear, Arizona

Posted by Admin on Fri, May 15, 2015 @ 11:02 AM

The Technical Challenge

The City of Goodyear, Arizona, is one of the fastest growing communities in the U.S. with an average annual growth rate of 15 to 20 percent. With growth exceeding the existing infrastructure capabilities, the City developed a program to quickly grow their potable water delivery capacity.  The brackish groundwater from local perched aquifers also required treatment for potable use in most cases.

Balancing Risk Reduces Design-Build Project Cost & Scheduled Time

Posted by Linda Hanifin Bonner on Tue, Apr 28, 2015 @ 04:14 PM

A major advantage for utility and agency owners who chooses a design-build procurement process is the flexibility to optimize overall project risk to reduce cost and schedule. In contrast with design-bid-build procurement, owners are limited by the contracting approach and regulations that separate responsibilities for design and construction, and do not value overall performance.

Covering the Risks in Design-Build: WDBC’s Response to ENR's Editorial

Posted by Admin on Tue, Apr 28, 2015 @ 03:28 PM

In Engineering News-Record's March 30 Editorial on “Covering Risks in Design-Build” delivery, a representative of the Association of General Contractors posted the question as to whether “design-build projects were introducing industry contractors to risks for which they are unprepared?” While AGC’s statements are directed to those in the mechanical, electrical, and plumbing industries – they can seriously misconstrue and/or misinterpret the successful achievements of allocating risks in water design-build projects contracts.

When Does Protecting the Owner's Best Interest Jeopardize the Project?

Posted by David Kinchen, WDBC Board President on Thu, Apr 16, 2015 @ 04:07 PM

As I reflect on this year's DBIA conference, I was encouraged by the dialogue between owners and practitioners during the General Session “Finding Common Ground Through Best Practices.” The open and candid discussion centered heavily on the key role owner's advisors (OA) and owner's engineers (OE) play during the life cycle of the project, from procurement planning through delivery and startup.
