How Machine Learning Can Help with Urban Development

March 27, 2019 — Aarni Heiskanen - AEC Business
An experimentation project has demonstrated the capabilities of machine learning in urban development. It used images as a starting point and came up with interesting and useful applications. “I read data science papers on how machine vision algorithms can be used with satellite imagery. I immediately saw a connection to what we had been doing,” Antti Kauppi, architect at Arkkitehdit Sankari, explains. “Most people associate image recognition with Google’s visual searches. Google can distinguish whether a photo shows a cat or another animal, for example. We went a step further.” An Experiment with Open Urban Imagery Arkkitehdit Sankari Oy, a Finnish architectural design firm began the experimentation project CityCNN in May 2018. It received funding from KIRA-digi, the Finnish government’s digitalization program for the built environment. CityCNN explored the possibilities of using machine learning and open data for urban development. Read the court decision

Enhanced Geothermal Energy Could Be the Next Zero-Carbon Hero

June 10, 2024 — Sidney L. Fowler, Robert A. James & Clarence H. Tolliver - Gravel2Gavel Construction & Real Estate Law Blog
Hydrogen, solar, wind—and even microwave beams from outer space—are a few of the alternative energies being explored as the world strives to cut the cord on carbon emissions. Recently, advancements in geothermal energy technologies appear poised to significantly expand geothermal’s reach. These new methods, varyingly referred to as enhanced, engineered or advanced geothermal systems (collectively referred to here as EGS), have recently made strides in scalability and grabbed the attention of changemakers. If successful, EGS may play a major role in the clean energy transition. The technique creates no emissions and is virtually limitless (it pulls from heat generated by the Earth’s core), and can provide constant baseload power, making it appealing to green-minded investors. This article calls attention to the progress and variety of EGS projects and proposals that Pillsbury sees as part of the ongoing energy transition. People have long been drawn to geothermal energy, with Paleo-Americans settling at hot springs some 10,000 years ago. In 1892, Boise, Idaho, became the first town to establish a district heating system that piped naturally occurring hot water from underground and into homes. It would take another 70 years for other cities to replicate the feat, but now 17 U.S. districts use such systems, along with dozens more worldwide. Reprinted courtesy of Sidney L.

U.S. Navy Sailors Sue Tokyo Utility Company Over Radiation Poisoning

April 09, 2014 — Beverley BevenFlorez-CDJ STAFF
In a one billion dollar lawsuit, U.S. Navy sailors contend that they “suffered massive doses of radiation” from the Fukushima Dia-ichi nuclear power plant in Toyko, Japan while stationed on the USS Ronald Reagan, reported the Orange County Register. A tsunami (caused by a 9.0 earthquake) flooded the plant, “cutting off electrical power and disabling backup generators.” The USS Reagan was sent to provide aid, but the plant then “blew up” before they arrived. “Sailors on the flight deck said they felt a warm gust of air, followed by a sudden snow storm: radioactive steam,” according to the Orange County Register. “Freezing in the cold Pacific air. Blanketing their ship.” However, the Orange County Register posed the question, “Could the Reagan – one of the most advanced nuclear aircraft carriers in the U.S. fleet – really not know that it was being showered with massive doses of radiation?” TEPCO, the company being sued by the sailors, answered that it’s “wholly implausible.” Read the court decision

Seventh Circuit Confirms Additional Insured's Coverage for Alleged Construction Defects

August 10, 2017 — Tred R. Eyerly - Insurance Law Hawaii
The Seventh Circuit held that the underlying complaint alleged an occurrence by asserting that the painting subcontractor was negligent in causing damage to the building. Westfield Ins. Co. v. Nat'l Decorating Serv., Inc., 2017 U.S. App. LEXIS 12516 (7th Cir. July 13, 2017). McHugh Construction, the general contractor for construction of a 24 story condominium building in Chicago, retained National Decorating Service, Inc. as a subcontractor to perform all of the painting work. This meant National Decorating would paint the exterior of the building with a protective coating that was a waterproof sealant. After completion, the building's board of managers sued McHugh, National Decorating, and others for damages resulting from faulty workmanship. The third amended complaint alleged: (1) significant cracking of the exterior concrete walls, interior walls, and ceilings; (2) significant leakage through the exterior concrete walls, balconies, and windows; (3) defects to the common elements of the building; and (4) damage to the interior ceilings, floors, interior painting, drywall, and furniture in the units.

Defects in Texas High School Stadium Angers Residents

March 07, 2014 — Beverley BevenFlorez-CDJ STAFF
According to WFAA News, many residents of Allen, Texas were upset when their tax dollars were spent on a new high school football stadium, and they are angry now that alleged construction defects may cause the stadium to close, and perhaps not even reopen again this fall. There “is a disproportionately large amount of our tax dollars that goes just to Allen ISD," Rachel Palmer, an Allen resident, told WFAA News. However, Ben Pogue, president of Pogue Construction, the stadium’s general contractor called the situation “a road bump.” WPAA News also interviewed Dr. Simon Chao of the Department of Civil Engineering at the University of Texas at Arlington: "Cracking is fairly common in concrete," Chao stated. "The problem is the damage water may cause by getting in the cracks.” Read the court decision

“License and Registration, Please.” The Big Risk of Getting Busted for Working without a Proper Contractor’s License

July 25, 2021 — Christopher A. Henry & Mia Hughes - ConsensusDocs
The need for contractors to maintain the proper contracting license may seem like a mundane, clerical detail, and generally is just that. If, however, the contractor ignores or mishandles paperwork and the proper license is not in hand, licensing may go from a mundane, clerical detail to a financial catastrophe. An unlicensed contractor may be barred from asserting claims or collecting payments for work already performed; the contractor may even be required to return payments for unlicensed work performed. A recent case in Georgia, a state that had no state-wide general contractor’s license requirement in effect until 2008 illustrates the risk of unlicensed work.[1] In Saks Management and Associates, LLC v. Sung General Contracting, Inc.,[2] the court ruled that without a license the general contractor did not have the right to enforce a contract. The contractor’s claims for payment failed, and the mundane, clerical error led a major financial loss. This disastrous result for the Georgia contractor is far from an outlier, and is a real risk in many states. Reprinted courtesy of Christopher A.
