Designing the Process to Deliver Zero-Carbon Construction – Computational Design in Practice
January 04, 2023 —
Peter Debney - AEC BusinessComputational Design is generating increasing interest in the construction industry as well as a certain amount of confusion. It is not parametric design; instead it takes parametric design to the next level. It is a set of methods that will define how we design structures over the next decades.
With Computational Design, you don’t design the building; you design the automated process to find the best building design.
Why use Computational Design?
Computational Design is enabling us to create buildings that are far more efficient than we can manage using more traditional methods. Some architects are indeed using it to produce novel building forms, but its great advantage is in helping us towards efficient, zero-carbon construction.

How Tech Is Transforming the Construction Industry in 2019
July 08, 2019 —
Ginger Butz - Construction ExecutiveThe immediate applications and benefits of Industrial Internet of Things technologies are obvious in industries like manufacturing and computing, but these digital transformation technologies may not be top of mind for construction managers.
It’s time for that mindset to change. Worldwide spending on IIoT is expected to reach nearly $2 trillion in 2022, proving that these technologies hold a significant amount of value to the industries using them. That rings especially true in construction, where IIoT stands to bolster an already significant commitment to safety and communication. Construction managers should keep these technologies firmly on the radar when making investments in 2019.
Smart equipment
With sensors and radio-frequency identification (RFID) tags, even legacy construction equipment can become part of a construction company’s IIoT fleet. The data collected from these machines provides construction managers with a wealth of knowledge around downtime, safety, labor, efficiency and more.
Additionally, the next era of smart construction equipment will feature more autonomous vehicles and automatic equipment shutdown, both of which promote worker safety. Autonomous vehicles, which self-correct based on feedback and environmental factors, also free up human engineers to move from maintenance tasks into more complex roles that leverage the feedback data reported by IIoT machinery.

Replacement of Defective Gym Construction Exceeds Original Cost
January 22, 2013 —
CDJ STAFFAustin, Texas has torn down a school gym, the Turner-Roberts Recreation Center at the Overton Elementary School, due to structural problems which became evident after the gym was completed four years ago. The cost of the new gym is $6.4 million, more than the cost of building the gym in the first place. The city is paying $3 million in repair costs with the rest of the money coming from the companies that designed and built the now demolished gym. According to the Austin Statesman, the total cost to the city will be about $8.6 million.
The Turner-Roberts Recreation Center cost $5.6 million to build, but soon after it opened, structural problems were discovered. Cracks formed in walls and glass doors buckled. The settlement with the designer, contractor, and engineering firm did not require the firms to admit fault as they paid $3.4 million to fix the situation. The Statesman was unable to get a breakdown of how much each firm paid. Tom Cornelius, president of the GSC, the architectural firm on the project told the Statesman that "the foundation issues were not caused by design defects."
Initially, the city sought to repair the gym, but early excavation determined that the defects were too extensive. In addition to the structural flaws, it was also determined that the HVAC system was faulty. Excavation also damaged plumbing work. Tearing down the gym turned out to be the most cost-effective response.

Safer Schools Rendered Unsafe Due to Construction Defects
February 10, 2012 —
CDJ STAFFBuilt on a program for safer school buildings, schools in Neenan County, Colorado have been shown to have mild-to-moderate structural problems, rendering some of them unsafe. The Denver Post reports that a third-party review of schools built by the Neenan Company has shown structural issues in all fifteen school buildings.
One school, Meeker Elementary, has been closed as it could collapse under high winds or during an earthquake. Sargent Junior-Senior High School is in use, but there are plans to evacuate the buildings if winds exceed 25 mile per hour. Two schools have roofs that are unable to bear expected loads of snow during the winter.
The Neenan Company says that the school buildings are not up to their standards and is working with the school districts to repair the buildings. Repairs are expected to be complete by August.

Nevada Supreme Court Rejects Class Action Status, Reducing Homes from 1000 to 71
July 02, 2014 —
Beverley BevenFlorez-CDJ STAFFThe Las Vegas Review-Journal reported that the “Nevada Supreme Court has rejected a request for class action status for claims of damaged stucco from faulty construction by Del Webb Communities involving nearly 1,000 Sun City Summerlin residents,” however, “the court upheld the award of damages to 71 homeowners following a jury trial in Clark County District Court in 2008.”
The case began in 2003, and the Las Vegas Review-Journal referred to it as “one of the largest construction-defect cases in Nevada history.” But District Judge Allan Earl denied class action lawsuit in 2006. “Attorneys were seeking $70 million for the homeowners.” In 2008, another court “determined that only 71 homeowners merited compensation totaling $4 million for the stucco issues.”
According to the Las Vegas Review-Journal, “[h]omeowners alleged that Del Webb failed to install metal screeds that would protect homes from water damage, and as a result, the homes suffered from cracked stucco, mold and weakened walls.”

Differing Rulings On Construction Defect Claims Leave Unanswered Questions For Builders, and Construction Practice Groups. Impact to CGL Carriers, General Contractors, Builders Remains Unclear
March 07, 2011 —
CDJ STAFFIn the past year a number of state and federal courts have rendered a number of conflicting decisions that promise to alter or perhaps shift entirely the paradigm, of how builders manage risk.
According to a report today by Dave Lenckus in Property Casualty 360 “Nine state and federal courts and one state legislature over the past year have addressed whether a construction defect a defective product or faulty workmanship is fortuitous and therefore an occurrence under the commercial general liability insurance policy. Four jurisdictions determined it is; three said no; two ruled that a construction defect that causes consequential damage to property other than the work product is an occurrence; and one federal court contributed its conflicting case law that has developed in Oregon since its high court ruled in 2000 that a construction defect is not an occurrence”.
The article strongly suggests that in the absence of a clear consensus over what the recent rulings mean for builders and contractors coverage disputes will intensify and continue to proliferate.
Doing this on a state-by-state basis has caused a lot of confusion among buyers and sellers, said Jeffrey A. Segall, a Tampa-based senior vice president and the Florida Construction Practice leader at Willis of Florida, a unit of Willis Group Holdings.

Eleventh Circuit Set to Hear Challenge to Florida Law Barring Foreign Citizens From Buying Real Property
April 22, 2024 —
Michael Gnesin - Lewis BrisboisFort Lauderdale, Fla. (April 2, 2024) - This month, the U.S. Court of Appeals for the Eleventh Circuit will hear a challenge to a recently-enacted Florida law, Senate Bill 264, which restricts foreign ownership or investment in Florida real property from specific countries and imposes a near ban on property purchases by Chinese, Russian and other foreign nationals.
On July 1, 2023,
Senate Bill 264 [codified under Fla. Stat. Ann. §§ 692.201 to 692.205] took effect. The bill, titled “Interests of Foreign Countries,” prohibits Chinese nationals and nationals from other countries, including Russia, from buying real property unless they are American citizens or permanent residents.
Prior to the new law's effective date, on May 22, 2023, four Chinese citizens who hold nonimmigrant visas and reside in Florida, along with a Florida-based real estate firm,
sued the state of Florida in federal district court, alleging that the new law is unconstitutional and discriminatory, and that it violates the Fair Housing Act [Shen v. Simpson, Case No. 4:23-cv-208].

Scientists Are Trying to Make California Forests More Fire Resilient
June 21, 2021 —
Laura Bliss - BloombergTo the untrained eye, the scrubby slope off Wentworth Springs Road in the Eldorado National Forest looks like any other patch of Sierra Nevada ridgetop. Tufted in native shrubs and flecked by darkened pine stumps, it’s part of a 30,000-acre swath of land that was deforested in 2014, when the King Fire tore through 17 miles of canyon in less than six hours.
But Dana Walsh can see what’s unique. On a recent Sunday morning, the USDA Forest Service forester bent over a white flag pinned into the ground to mark a barely-visible seedling. As she points to other seemingly camouflaged baby conifers nearby, what starts to emerge is a subtle pattern she calls cluster planting.
“It’s tough to make out unless you know to look for it,” she said. “But once you see a tree, then you can spot the five or six planted near it. Then there’s nothing. Then there’s another five or six. Then there’s nothing.”
