How Algorithmic Design Improves Collaboration in Building Design
June 18, 2019 —
Aarni Heiskanen - AEC BusinessDesign, like everything else in a construction project, is a collaborative effort. Even with digital tools, collaboration across design disciplines is not yet optimal. An experimental project thus set out to test whether algorithmic design could help streamline the interaction between architects and structural engineers.
Design data originating from an architect is used in several engineering tools for visualization, analysis, and calculation. Ideally, changes in the architect’s design would propagate automatically across all the software. Unfortunately, the process is in fact mostly manual. Hence, the design data is seldom, if ever, in perfect sync on all systems.

Factories Boost U.S. Output as Builders Gain Confidence: Economy
June 18, 2014 —
Victoria Stilwell – BloombergAmerican manufacturers are churning out more goods and homebuilders are regaining confidence as evidence mounts that the world’s largest economy is making a comeback after a slow start to 2014.
Output at factories, mines and utilities rose 0.6 percent in May, reflecting gains at makers of automobiles, business equipment and construction supplies, according to Federal Reserve data today in Washington. Builder sentiment this month jumped by the most in almost a year, another report showed.
Improving consumer and business spending means assembly lines will probably remain busy in the second half of the year, giving growth a boost after the expansion sputtered in the first quarter. The reports, which came as the International Monetary Fund cut its 2014 forecast for the U.S., give Fed policy makers meeting this week reason to continue trimming stimulus at a measured pace to ensure the rebound is sustained.
“We’re back on track,” said Michael Feroli, chief U.S. economist at JPMorgan Chase & Co. in New York, and the second-best production forecaster over the last two years, according to data compiled by Bloomberg. “Everything is growing at a pretty good clip.”

Commonwealth Court Strikes Blow to Philly Window and Door Ordinance
January 05, 2017 —
Wally Zimolong – Supplemental ConditionsOn December 22, 2016, the Pennsylvania Commonwealth Court issued an important opinion that has flown under the radar somewhat. The case Rufo v. Board of Licenses and Inspection Review, invalidates a major portion of Philadelphia’s so called windows and doors ordinance, which requires owners of vacant properties to install glass windows and doors with frames on vacant properties. A copy of the opinion can be found here. (I only learned about the case because of a tweet by a litigator with the pro-freedom group the Institute for Justice.)
The Windows and Doors Ordinance
The case concerns Section 306.2 of the Property Maintenance Code which requires “the owner of a vacant building that is a blighting influence, as defined in this subcode, [to] secure all spaces designed as windows with windows that have frames and glazing and all entryways with doors.” Property owners found in violation of the ordinance can face stiff fines. Property owners are subject to a daily fine for each door and window in violation of the Ordinance. The fine is $300 per window or door. However, because most vacant properties have multiple windows and doors the fines can add up exponentially.

Contractor Manslaughter? Safety Shortcuts Are Not Worth It
August 11, 2011 —
Douglas Reiser, Builders Council BlogIt’s been a while since I discussed the importance of safety. But, a recent article on ENR.com compelled this brief article. Don’t shortcut safety — you could be facing serious criminal repercussions.
A New York crane company owner and one of his employees are each facing a second-degree manslaughter charge for the death of two construction workers.  The charges stem from the collapse of a crane in New York City. The district attorney determined that the crane owner cut a few corners to reduce its operation costs, significantly sacrificing safety.
Another example was the 2010 trial of another New York crane operator who was charged with manslaughter. In that case, the criminal charges failed to stick, but an administrative judge found that the contractor used a damaged sling to support the steel collar binding the tower-crane mast to the 18th floor of a high-rise building being constructed. The company also used four slings instead of the eight, as specified by the crane manufacturer; improperly attached the slings and failed to pad or soften them.

Affordable Housing, Military Contracts and Mars: 3D Printing Construction Potential Builds
September 05, 2022 —
Adam J. Weaver & Lindsey Mitchell - Gravel2Gavel Construction & Real Estate Law BlogThe 3D printing construction market is likely on the cusp of a boom.
This unique construction method boasts many advantages in comparison to traditional forms of construction. Projects can be completed more quickly and at a fraction of the cost, given fewer laborers are required and the materials used are much cheaper. Though market growth stalled during the COVID-19 pandemic, industry leaders expect 3D printing construction to experience exponential growth in the coming years.
While 3D printing technology has risen in popularity and prominence in the past couple of decades, it is only recently that 3D printing companies have begun making strides in the construction industry. Critical to the construction process is the software that is used to create and model the planned structure. A software program turns a building’s blueprint into code that then dictates the movement of a 3D printer on the construction site. After a concrete-like mix is loaded into the printer, the printer begins to build the walls by laying one cylindrical layer of concrete at a time, in accordance with the blueprint. There is no one-size-fits-all approach in 3D printing construction: some companies print the core structure as well as the roof and floor of the structure, while others print only the core and shell and install those portions separately using traditional methods and materials.

Weslaco, Texas Investigating Possible Fraudulent Contractor Invoices
March 19, 2014 —
Beverley BevenFlorez-CDJ STAFFThe city of Weslaco in Texas fears that they have received “fraudulent invoices from the contractor of the…Valley Nature Center facility,” according to the Mid-Valley Town Crier. The project had been stalled due to “problems with numerous subcontractors claiming they hadn’t received payment.” Furthermore, “[c]onstruction is more than 14 months delayed and now halted as contractor GAS Enterprises demands more money from the city.”
City Manager Leo Olivares informed GAS President Rene Salinas “that the city was aware of ‘forged requests for payments,’ ‘padding invoices’ and ‘requests for reimbursement for items, materials and labor that you did not pay,’” reported the Mid-Valley Town Crier. While Salinas did not respond to the Mid-Valley Town Crier when asked for a comment, he did send a letter to the city “arguing that none of the subcontractors had questioned the documents to him.”

EPA Fines Ivory Homes for Storm Water Pollution
June 26, 2014 —
Beverley BevenFlorez-CDJ STAFF“Utah’s largest home builder [Ivory Homes] has agreed to a $250,000 fine and to take several steps…to comply with Clean Water Act requirements to control pollution associated with storm-water runoff from construction sites,” reported The Salt Lake Tribune.
David Broadbent, Ivory Homes’ chief operating officer, stated in an email to The Salt Lake Tribune: “We are proud of our environmental record, particularly our storm-water compliance record. We are the first and the only home builder in Utah to implement a robust, companywide program to safeguard against sediment from entering Utah waters as a result of home-building activities.” Furthermore, Broadbent declared that the “inspections that led to the violations notices” did not yield any evidence that their “home-building practices resulted in any sediment discharge in any amount, let alone harm, to Utah waters.”

Domtar Update
June 11, 2014 —
Robert M. Caplan – White and Williams LLPOn May 29, 2014, the Pennsylvania Supreme Court granted allocatur—i.e., the permission to appeal—in the controversial subrogation case, Liberty Mutual Ins. Co. v. Domtar Paper Co., 77 A.3d 1282 (Pa. Super. Ct. 2013). In its order granting the relief to Liberty Mutual, a workers’ compensation insurer, the Supreme Court set forth the narrow issue to be decided on appeal: “Does Section 319 of the Pennsylvania Workers’ Compensation Act, 77 P.S. § 671, allow the employer/insurer to step into the shoes of the insured employee to subrogate against the tortfeasor?”
In Domtar, Liberty Mutual was caused to incur approximately $35,000 in compensation benefits which it paid on behalf of George Lawrence, an employee of Liberty Mutual’s insured, for injuries he sustained in a work-related accident. Mr. Lawrence chose not to file an independent personal injury lawsuit. As a result, in order to recover its lien interests, Liberty Mutual sued the third parties responsible for causing Mr. Lawrence’s work-related injuries directly, having become subrogated to the rights of Mr. Lawrence by virtue of Liberty Mutual’s workers’ compensation expenditure on his behalf.
