Will the Hidden Cracks in the Bay Bridge Cause Problems During an Earthquake?
June 26, 2014 —
Beverley BevenFlorez-CDJ STAFFDespite a “no cracks” welding code and contract provision for the San Francisco-Oakland Bay Bridge, in 2008 Caltrans proceeded with the project despite welding cracks created by the Chinese firm hired to build the roadway, according to the Sacramento Bee. By the time the cracks had been discovered, the costs were at $6.5 billion and climbing, and fixing the cracks would be time-consuming and expensive.
However, there is some dispute as to rather the welding “cracks represent a hazard to the traveling public.”
“Examine history,” Brian Maroney, Caltrans’ chief engineer for the bridge, said in a recent interview by the Sacramento Bee. “… Caltrans reviewed major quakes around the globe and never found a case in which weld cracks caused bridge-roadway fractures.”
However, the Sacramento Bee reported that there was a case where welding cracks led to fractures. For instance, after the southern California earthquake in 1994 centered in Northridge, the Santa Clara River Bridge “suffered several fractures in steel girders. The breaks were traced to tiny cracks in welds, likely present before the quake, and worsened by vibrations of heavy trucks passing overhead. When the quake struck, the girders fractured.”
The Santa Clara bridge did not collapse. Sacramento Bee claimed it remained standing because the I-beam-shaped girders were “not fracture-critical.” However, the Bay Bridge’s “roadway consists of box-girder segments welded together. In effect, they create one contiguous, fracture-critical girder,” Abolhassan Astaneh-Asl, UC Berkeley engineering professor told the Sacramento Bee. “If welds crack and grow rapidly during a large quake, the entire roadway could fail.”

Sales of U.S. New Homes Decline After Record May Revision
July 30, 2014 —
Victoria Stilwell – BloombergFewer new U.S. homes were sold in June than forecast and May data showed the biggest downward revision on record, painting a picture of a housing market that is struggling to gain traction.
Sales of newly built homes declined 8.1 percent to a 406,000 annualized pace, the fewest since March and less than any economist surveyed by Bloomberg forecast, Commerce Department figures showed today in Washington. That followed a May reading of 442,000 that was 12.3 percent lower than estimated last month.
Restrictive lending rules, limited land supply, higher mortgage rates and more expensive properties are keeping a lid on how much the housing recovery can accelerate. Continued employment gains and bigger increases in wages will be needed to support further growth in the industry, which has stalled since interest rates started climbing last year.

Exploring Architects’ Perspectives on AI: A Survey of Fears and Hopes
March 19, 2024 —
Aarni Heiskanen - AEC BusinessRIBA, the Royal Institute of British Architects, ran a survey in late 2023 with 500 respondents on the impact of AI on their profession. The study also explored the near-term outlook for AI adoption and use. The results reveal divided opinions among architects. A popular view is that AI threatens the profession, even though a larger portion sees tools like AI as necessary in the coming years.
The Present Use of AI
The respondents were asked, for the projects they are currently working on, how often their practice used AI in any way.
In all, 41% said that they use AI to some degree. Of those, 43% agree that AI has improved efficiency in the architectural design processes, while 24% disagree.

Northern District of Mississippi Finds That Non-Work Property Damages Are Not Subject to AIA’s Waiver of Subrogation Clause
July 11, 2018 —
Shannon M. Warren - The Subrogation StrategistIn recent months, the Northern District of Mississippi has grappled with how to interpret waivers of subrogation in American Institute of Architects (AIA) construction industry contracts and, specifically, how they apply to work versus non-work property. The distinction between work and non-work property has been commonly litigated and remains a hotly debated topic when handling subrogation claims involving construction defects.
In Liberty Mutual Fire Ins. Co. v. Fowlkes Plumbing, 2018 U.S. Dist. LEXIS 23515 (February 12, 2018), a fire consumed the entire insured risk when one of the defendants was performing window restoration services. Subsequently, the insured’s subrogated insurer filed suit against several defendants involved in the construction project at issue. In response to the defendants’ motion for summary judgment, the District Court for the Northern District of Mississippi considered whether the waiver of subrogation clause in AIA contract form A201-2007 precluded the subrogated insurer from recovering damages from the defendants. The court held that the waiver of subrogation provision contained in AIA document A201-2007 barred the insurer from recovering for damages to the work itself, but did not apply to non-work property.

After 60 Years, I-95 Is Complete
September 10, 2018 —
Riley Griffin - BloombergAcross the U.S., public infrastructure is crumbling because of legislative gridlock and chronic underfunding. Roads are overcrowded, bridges are well past their expiration date, and transit systems regularly face unprecedented delays. But there will be one thing to celebrate as you seethe in beach traffic this weekend—a small, strange gap in I-95 is being filled.
Come September, one of the most audacious public infrastructure projects in U.S. history will be completed after more than six decades of work. Interstate 95 was the crown jewel of the American highway system championed by President Dwight Eisenhower, and yet the plan for an artery stretching the length of the East Coast almost didn’t happen—because of local lawmakers and land-owners in Mercer County, New Jersey.

General Contractors: Consider Importance of "Primary Noncontributory" Language
February 16, 2017 —
David Adelstein – Florida Construction Legal UpdatesIn prior articles, I reinforced the importance of general contractors including “primary and noncontributory” language in subcontracts and requiring the subcontractor to provide an analogous “primary and noncontributory” endorsement. As a general contractor this is important, particularly since you are going to require the subcontractor to (i) indemnify you for claims relating to personal injury, property damage, or death, and (ii) identify you as an additional insured under its commercial general liability (CGL) policy for claims arising out of the subcontractor’s scope of work. The “primary and noncontributory” language in your subcontracts allows you to maximize the value of your additional insured status.

California Case Adds Difficulties for Contractors & Material Suppliers
August 20, 2014 —
Beverley BevenFlorez-CDJ STAFFGarret Murai in his California Law Blog declared that “things just got a lot tougher for contractors and material suppliers in the Golden State.” In his blog, Murai analyzed the recent case Golden State Boring & Pipe Jacking, Inc. v. Eastern Municipal Water District, Case No. E054618 (July 23, 2014), in which “the California Court of Appeals for the Fourth Appellate District found that a subcontractor’s public works payment bond claim was time barred because its stop payment notice was served ‘before’ a notice of completion was recorded.”
Murai explained the importance of the ruling and how it changed the status quo: “Whereas before, it was commonly understood that you could serve a stop payment notice ‘during’ construction (after all, that was the point wasn’t it, to stop construction funds before they are paid out), now you may have only have a 30 day window (probably less) to serve a stop notice within 30 days after a notice of completion or notice of cessation is recorded.”

Catch 22: “If You’re Moving Dirt, You Need to Control Your Dust” (But Don’t Use Potable Water!)
February 18, 2015 —
Stephen McKae – California Construction Law BlogReturning from an Oregon vacation this past Summer along I-5, I found frequent reminders of the extraordinary drought conditions prevailing across California. A grey smoky gloom blanketed the California-Oregon border from Ashland to Weed from at least five wildfires. The prediction of rains in the north state was more curse than blessing as lightning threatened to touch off tender-dry fuel in the forests and start more fires. Farmers tilling fields produced massive dust clouds. And under the I-5 bridge along the Sacramento River arm of Lake Shasta, the lake had receded to the original streambed.
On NOAA’s Palmer Drought Severity Index, nearly all of California is listed as in a condition of extreme or severe drought, and the Governor has issued a Proclamation of Continued State of Emergency requiring water conservation measures affecting all California residents. Indeed, early August news reports indicate that hopes of relief from an El Nĩno year are waning. The State Water Resources Control Board’s Emergency Regulation No. 2014 issued July 15 mandates action to reduce water use and require larger water suppliers to activate their Water Shortage Contingency Plan. The emergency regulation will remain in effect until April 25, 2015 unless extended due to ongoing drought conditions.
