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

Contract Disruptions: Navigating Supply Constraints and Labor Shortages

January 24, 2022 — Greg Ross & Tim Lynch - Construction Executive
The biggest worries in today’s economy—supply chain disruptions, labor shortages and the worst inflation in decades—are creating big headaches in the construction industry. What’s worse, large projects underway are often based on contracts hammered out pre-pandemic, before the uncertainties and disruptions that spread around the globe with COVID-19. Construction firms find themselves executing on contracts signed when the potential for delayed timelines and rising costs seemed more remote. A recent report from the U.S. Chamber of Commerce finds almost all contractors (93%) say they are experiencing a shortage of an important product such as steel, lumber or copper. A rising number of companies on commercial projects (54%) also cite difficulty finding skilled workers. Grant Thornton clients, among them some of the country’s biggest construction companies, report that sourcing materials and hiring workers is a bigger challenge today—and more expensive—than at any other time in recent decades.

Six Reasons to Use Regular UAV Surveys on Every Construction Project

October 14, 2019 — Dustin Price - Construction Executive
UAVs are the future of the construction industry. From accurate 3D modeling simulations to regular safety and maintenance checks, UAVs can improve construction projects in many ways—and the value and applications for UAVs is consistently growing. Drones are agile, cost-effective and safe. Here are some reasons why UAV surveys should be part of any construction project. 1. UAV scans are much faster than human inspections Drones can cover large territory much faster than human inspectors can. They can also be used over more difficult terrain, and they can survey areas that are otherwise inaccessible. A drone survey can be completed in a day; not only does this mean that the territory is well-surveyed each time, but it also means surveys can be done more frequently. Construction projects need to be inspected regularly and on time if the project is to meet its deadlines. Delayed construction projects can cost a company millions of dollars, as construction projects need to be completed stage by stage, usually on a strict timeline. Drones will improve the consistency of the project and, in turn, this will improve the reputation of the company itself.

Natural Hydrogen May Seem New in Town, but It’s Been Here All Along

April 22, 2024 — Elina Teplinsky & Sheila McCafferty Harvey - Gravel2Gavel Construction & Real Estate Law Blog
When it comes to renewable energy, hydrogen is hailed as a pivotal resource in the zero-carbon game plan. Hydrogen energy is accessible, produces lower greenhouse gas emissions and can use existing gas infrastructure to power electricity and heat, produce other gases and fuels, and more. Recently, a “new” type of hydrogen—has captured the attention of climate scientists. Natural hydrogen—often referred to as gold hydrogen—stands apart from other, more established types of hydrogen, which require extraction and expensive maneuvering to produce. Natural hydrogen exists underground in its pure form (i.e., it’s not combined with other molecules). Estimates vary, but some researchers suspect that Earth holds as much as five million megatons of hydrogen beneath our feet. Extracting just 2 percent of that supply, in theory, has the potential to get us to net-zero emissions for 200 years. From Past Prediction to Accidental Discovery Viacheslav Zgonnik, CEO of the Denver-based startup Natural Hydrogen Energy, told the New York Times that Russian chemist Dmitri Mendeleev (also known as the “Father of the Periodic Table”) wrote about the presence of natural hydrogen as long ago as 1888. Somehow, the information was lost along the way, and when pockets of such hydrogen were occasionally found, they were treated as anomalies.

Insurer's Motion for Summary Judgment on Faulty Workmanship Denied

June 04, 2024 — Tred R. Eyerly - Insurance Law Hawaii
The court found that the insurer failed to meet its burden on summary judgment seeking a judgment that faulty workmanship precluded coverge. Auto-Owners Ins., Co. v. AAA Discount Homes, LLC, 2024 U.S. Dist. LEXIS 48463 (S.D. Ga. March 19, 2024). Heather Way sued AAA Discount Homes, LLC and Delta Transport & Management, Inc. for manufacturing defects found in a manufactured home which was delivered and assembled by Delta. Way had contracted with AAA for the construction, delivery, assembly, setting, tie down with brick underpinning steps and construction of front and back porches. AAA, assisted by Delta, delivered the home and assembled it, including raising the roof, over the course of a few days. Subsequently, Way discovered extensive water damage and mold in the home. Way alleged that AAA and its subcontractors made careless, unsafe, and unsuccessful attempts at removing the old and repairing the water damage. The presence of chemicals in the home made it uninhabitable. Way alleged the home was improperly assembled by Delta and its negligence resulted in damages. Read the court decision

Construction Defect or Just Punch List?

December 11, 2013 — CDJ STAFF
A couple in Dickinson, North Dakota have put big, green “buyer beware” signs on their home. They’re not planning on selling, but just trying to warn prospective neighbors of the problems they’ve had since moving into their new home. Andrea Thermes said her problems included leaking windows and uneven floors. “I absolutely love my house,” she said. “If we didn’t have the issues, I would be the happiest girl in the world.” One problem was a leaking picture window in her living room. The builder replaced it, but the first window that arrived was the wrong size. The new home is still under a warranty and the builder has been fixing issues as they arise. “They are upset with some of the problems they have had,” said William Henry, president of B-Dev, the builder of the home. Since Ms. Thermes’s window wasn’t repaired in time for Thanksgiving, Mr. Henry sent wine and beer to her home. “Not that that makes up for not having their window, but we’re trying to make this work and trying to appease them,” he said. But Mr. Henry said that some of the problems “are not really material defects,” characterizing them as “punch-list and warranty items.” Read the court decision

Reminder About the Upcoming Mechanic’s Lien Form Change

August 26, 2019 — Christopher G. Hill - Construction Law Musings
As July 1, 2019 approaches with its inevitable changes to the Virginia Code, I wanted to remind you once again that the statutory form for a Virginia mechanic’s lien will change as of that date. HB2409 passed both houses of the General Assembly and has been signed by the Governor. This bill reconciled the language found in Virginia Code Sec. 43-4 with the various forms for general contractor, subcontractor and sub-subcontractor/supplier forms found in later sections of the code. As you will see if you download the .pdf of the bill as signed, this involved some tweaks to 43-4 and some updates to the mechanic’s lien forms that are in the code. The recent Desai case from the Virginia Supreme Court made it clear that such action was necessary. Read the court decision

Supreme Court of Oregon Affirms Decision in Abraham v. T. Henry Construction, et al.

April 20, 2011 — Beverley BevenFlorez CDJ STAFF

After reviewing the decision in Abraham v. T. Henry Construction, et al., the Oregon Supreme Court affirmed that a tort claim for property damage arising from construction defects may exist even when the homeowner and the builder are in a contractual relationship.



When the case was initially filed, the plaintiffs alleged breach of contract and negligence. The defendants moved for summary judgment arguing that one, the claim was barred by the six-year statute of limitations and two, no special relationship (such as one between a doctor and patient) existed. The court agreed with the defendants. However, the Court of Appeals while affirming the trial court’s decision on breach of contract reversed the decision on negligence. The Court of Appeals stated that an administrative or statute rule could establish a standard of care independent from the contract.



The Oregon Supreme Court gave an example of cases where a tort claim could exist when a contract is present: “If an individual and a contractor enter into a contract to build a house, which provides that the contractor will install only copper pipe, but the contractor installs PVC pipe instead (assuming both kinds of pipe comply with the building code and the use of either would be consistent with the standard of care expected of contractors), that failure would be a breach of contract only. […] If the failure to install the copper pipe caused a reduction in the value of the house, the plaintiff would be able to recover that amount in an action for breach of contract. […] On the other hand, if the contractor installed the PVC pipe in a defective manner and those pipes therefore leaked, causing property damage to the house, the homeowner would have claims in both contract and tort. […] In those circumstances, the obligation to install copper instead of PVC pipe is purely contractual; the manner of installing the pipe, however, implicates both contract and tort because of the foreseeable risk of property damage that can result from improperly installed pipes.”
