GEI Completes Work on San Diego County Water Authority's $1.5B Emergency Storage Project with the Dedication of the San Vicente Dam Raise

The dam raise is the culmination of 22 years of GEI support to the Water Authority on the project

SACRAMENTO, Calif., Sept. 2, 2014 /PRNewswire/ -- GEI Consultants, Inc., one of the nation's leading geotechnical, environmental, water resources, and ecological science and engineering firms, announced today that its client, the San Diego County Water Authority, recently dedicated the San Vicente Dam Raise, the final major piece of the Water Authority's $1.5 billion Emergency Storage Project (ESP).  The ESP consists of a system of reservoirs, interconnected pipelines, and pumping stations that will ensure the region has a six-month supply of water in the event of an interruption of imported water deliveries.

GEI has provided engineering services to the Water Authority on a continuous basis for the last 22 years to bring the ESP to fruition, encompassing all project phases – planning, design, construction, and operation.  In addition to the San Vicente Dam Raise, the ESP has also included the following notable projects: Olivenhain Dam, the tallest roller compacted concrete (RCC) dam in North America; a pump station and tunneled pipeline to deliver Lake Hodges water to Olivenhain Reservoir, which also includes a pumped-storage component to generate hydroelectricity; and a pump station and 11-mile long large-diameter tunnel to connect San Vicente Reservoir with the regional aqueduct system. GEI assisted the Water Authority in obtaining environmental approvals for the ESP, and developed conceptual designs of all facilities, annual operation plans for storage reservoirs, emergency water delivery plans for allocating available supplies in an emergency event, and aqueduct operation plans for regional distribution of emergency water supplies.

The recently completed San Vicente Dam Raise expands the capacity of the reservoir by 152,000 acre-feet to over 242,000 acre-feet, which includes 100,000 acre-feet of carryover storage for use in times of drought.  The original 220-foot high concrete dam was raised 117 feet using RCC, making it the highest dam raise in the country and highest dam raise in the world using RCC.

GEI's scope of services for the dam raise included: planning studies to determine the optimal height of the raise; engineering analysis to support CEQA/NEPA documentation for the additional carryover storage component of reservoir expansion; seismicity analyses; a comprehensive geotechnical investigation program; inspection and analysis of the existing dam, hydrologic and hydraulic evaluations; conceptual designs for raising the dam and appurtenant structures; dynamic analyses of the composite concrete/RCC structure; dam breach inundation mapping; constructability analysis; cost estimating;  and development of reservoir operations plans for construction and post-construction. 

A critical element of the project was the conceptual design of a new outlet works system, involving construction in an active reservoir. GEI developed a cost effective concept for the new outlet works, involving a dual system consisting of an outlet works tower on one of the abutments and a separate low level outlet near the center of the dam. This concept reduced the amount of underwater construction, reduced costs, and reduced construction risks.

"GEI is proud to have played an integral role in the success of the Emergency Storage Project which is so vital to the San Diego region," said GEI president Raymond Hart.

DevOps has often been described in terms of CAMS: Culture, Automation, Measuring, Sharing. While we’ve seen a lot of focus on the “A” and even on the “M”, there are very few examples of why the “C" is equally important in the DevOps equation. In her session at @DevOps Summit, Lori MacVittie, of F5 Networks, will explore HTTP/1 and HTTP/2 along with Microservices to illustrate why a collaborative culture between Dev, Ops, and the Network is critical to ensuring success.
Today’s connected world is moving from devices towards things, what this means is that by using increasingly low cost sensors embedded in devices we can create many new use cases. These span across use cases in cities, vehicles, home, offices, factories, retail environments, worksites, health, logistics, and health. These use cases rely on ubiquitous connectivity and generate massive amounts of data at scale. These technologies enable new business opportunities, ways to optimize and automate, al...
You have your devices and your data, but what about the rest of your Internet of Things story? Two popular classes of technologies that nicely handle the Big Data analytics for Internet of Things are Apache Hadoop and NoSQL. Hadoop is designed for parallelizing analytical work across many servers and is ideal for the massive data volumes you create with IoT devices. NoSQL databases such as Apache HBase are ideal for storing and retrieving IoT data as “time series data.”
Clearly the way forward is to move to cloud be it bare metal, VMs or containers. One aspect of the current public clouds that is slowing this cloud migration is cloud lock-in. Every cloud vendor is trying to make it very difficult to move out once a customer has chosen their cloud. In his session at 17th Cloud Expo, Naveen Nimmu, CEO of Clouber, Inc., will advocate that making the inter-cloud migration as simple as changing airlines would help the entire industry to quickly adopt the cloud wit...
The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data...
There are so many tools and techniques for data analytics that even for a data scientist the choices, possible systems, and even the types of data can be daunting.

IT data is typically silo'd by the various tools in place. Unifying all the log, metric and event data in one analytics platform stops finger pointing and provides the end-to-end correlation. Logs, metrics and custom event data can be joined to tell the holistic story of your software and operations. For example, users can correlate code deploys to system performance to application error codes.
In his session at DevOps Summit, Bryan Cantrill, CTO at Joyent, will demonstrate a third path: containers on multi-tenant bare metal that maximizes performance, security, and networking connectivity.
Mobile, social, Big Data, and cloud have fundamentally changed the way we live. “Anytime, anywhere” access to data and information is no longer a luxury; it’s a requirement, in both our personal and professional lives.

There are many considerations when moving applications from on-premise to cloud. It is critical to understand the benefits and also challenges of this migration. A successful migration will result in lower Total Cost of Ownership, yet offer the same or higher level of robustness. Migration to cloud shifts computing resources from your data center, which can yield significant advantages provided that the cloud vendor an offer enterprise-grade quality for your application.
Overgrown applications have given way to modular applications, driven by the need to break larger problems into smaller problems. Similarly large monolithic development processes have been forced to be broken into smaller agile development cycles. Looking at trends in software development, microservices architectures meet the same demands. Additional benefits of microservices architectures are compartmentalization and a limited impact of service failure versus a complete software malfunction....
Manufacturing has widely adopted standardized and automated processes to create designs, build them, and maintain them through their life cycle. However, many modern manufacturing systems go beyond mechanized workflows to introduce empowered workers, flexible collaboration, and rapid iteration.
