Progressive Design-Build Delivery Retrofits a Water Treatment Plant

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.

Project Spotlight: Arizona’s Agua Nueva Water Reclamation Facility

Partnering to Promote Best Design-Build Practices in Pima County, Arizona Jacobs partnered with Pima County to implement one of the world’s most advanced water reclamation facilities: the Agua Nueva Water Reclamation Facility. As the single-entity designer, builder and operator, Jacobs combined its integrated delivery capabilities and penchant for technical excellence to create an industry-first wastewater treatment process that saves taxpayers’ money and conserves resources in Arizona’s water-starved climates.

Project Spotlight: Quincy, Washington Industrial Water Reuse Utility

Third-Party Contracting and Public/Private Collaboration Open the Door to Design-Build in the City of Quincy, Washington To maintain operability, data centers demand abundant amounts of low-cost power, reliable infrastructure, mild weather, low-risk seismic zoning, buried power lines and reasonably priced Greenfield land. Since 2006, these criteria have made the city of Quincy, Washington, an ideal location for farming, food processing, and data centers. Located in Grant County, the largest potato producing county in the United States, the city of Quincy is home to over 60 megawatts (MW) of server farms for Microsoft, Dell, Yahoo!, Intuit and others.

Project Spotlight: Orlando Wastewater Treatment Discharge Project

In an effort to relocate freight traffic out of Orlando, Florida, CSX offered to purchase the City of Winter Haven’s 1,200-acre spray field for the development of an intermodal station. The City was interested in selling the property in order to gain the financial benefit of the sale price and to create economic development and additional tax revenue for the community.

Answering Questions about CMAR and Design-Build Delivery

During a recent education and discussion session with a state regulatory agency the following questions pertaining to the differences in design-build and CMAR delivery were addressed. The responses on these topics are provided below. Currently, most State SRF and DWRF programs require completion and approval of design prior to construction as well as a competitive bidding process.

Allocation of Risk and Liability in a Design-Build or CMAR Project

Risk and liability allocation in a design-build or CMAR contract generally follows the principle that risks should be allocated to the party in the best position to manage them. Whether it is the owner or the design-build or CMAR firm that prepares the contract, a risk allocation matrix can provide a useful starting point. A risk allocation matrix identifies potential risks across a project and then allocates or shares these risks between the owner and a firm. The objective is to reduce the owner’s risk-related costs by taking into account the following concepts.

Progressive Design-Build Procurement Selection Process

Progressive design-build procurement enables an owner to select the design-builder on the basis of qualifications. It is recognized, however, that some owners may not want, or may not have the ability (due to applicable law), to base selection solely on qualifications. The WDBC model documents, therefore, include RFQ and RFP templates for best-value (incorporating both price and non-price factors), as well as qualifications-only selection.

Project Spotlight: Charnock Well Field Restoration Project (CA)

Charnock Well Field Restoration Project

Serving a population of nearly 90,000, the Santa Monica Water Treatment Plant and the city’s Charnock Well Field stand as examples of the issue faced by many utilities throughout the United States—limited fresh water supplies, mixed and/or emerging contaminants, and tighter regulations. After more than a decade with the Charnock Well Field closed due to contamination from MTBE (a gasoline additive), the City reached a settlement agreement with the three major oil companies, whose leaking underground storage tanks caused the contamination. The settlements would fund a restoration project on the facilities. On the heels of the lengthy settlement process, Santa Monica faced an urgent need to move toward water self-sufficiency.
