Design flaws, construction shortcomings and maintenance errors caused the Oroville Dam spillway to break apart in February, according to an independent analysis by Robert Bea for the Center for Catastrophic Risk Management at UC Berkeley.
Bea, a co-founder of the center and retired civil engineering professor, found that in the 1960s, when the dam was being planned, designers did not call for a thick enough concrete spillway floor. Nor did they require the continuous steel reinforcement needed to keep its slabs intact during decades of service.
The design also did not require strong enough anchors into the underlying mountainside to resist movements downhill and from side to side.
The analysis is the first major assessment of what caused the massive damage that forced the evacuation of nearby Oroville and left the state with a repair bill likely to reach into the hundreds of millions of dollars.
It also sends a warning that the state’s aging fleet of dams may contain unknown defects that would threaten public safety in future wet years.
California Department of Water Resources spokeswoman Erin Mellon said the agency has not seen Bea’s analysis.…

An Aventura-based architecture firm allegedly left McKafka Development Group hanging, delaying construction on its 90-unit high-rise called the Crimson in Miami’s Edgewater neighborhood, according to a lawsuit.
McKafka, through its limited liability company Alpine Estates, accuses International Design Engineering and Architecture, or I.D.E.A. for short, of breaching its contract and negligence, in the lawsuit filed in Miami-Dade Circuit Court last month.
Stephane L’ecuyer, I.D.E.A.’s principal, did not return two phone messages seeking comment. McKafka principal Stephan Gietl also did not respond to The Real Deal, but his lawyer Bruce King said, “We had several discussions to get a resolution and have been unable to do so.” He declined further comment.
According to the lawsuit, McKafka hired I.D.E.A. on Feb. 8, 2013 as the architect of record and Facchina Construction of Florida as the general contractor for the Crimson. However, the architecture firm performed poorly, the lawsuit alleges. The Crimson, at 601 Northeast 27th Street, remains unfinished today.
“I.D.E.A. failed to timely coordinate with or respond to Facchina, prepared incomplete or inconsistent drawings and specifications, and failed to perform in a manner consistent with the design schedule,” the lawsuit states.
McKafka alleges that I.D.E.A. also failed to timely respond to requests for information, change order requests, or provide staff to ensure continuity of service. In addition, according to the suit, I.D.E.A. improperly designed the garage ramps that led to substantial structural changes. The company also improperly designed the temperature control system, resulting in high humidity in the condo units, the lawsuit alleges.
Other significant revisions at the Crimson included the relocation of piles and beams and the redesigning of the height of the building’s stairs and the size of an emergency generator room, McKafka alleges. As a result of the repairs and revisions, the project was delayed and Facchina charged the developer for the delays, as well as additional construction costs, according to the suit.…
