One Industry, One Goal: Construction Safety Week 2026

May 05, 2026 — Maggie Murphy - Construction Executive
Construction safety has long been a top priority across the industry. Yet fatality rates have remained stubbornly flat for more than a decade. Steven Carter, global health and safety director at Gilbane chair company for Construction Safety Week 2026—believes the industry has reached a pivotal moment. This year’s theme—”All In Together: Recognize. Respond. Respect.”—is a unified call to action for owners, designers, contractors and craft professionals around a shared, risk-based approach to preventing serious injuries and fatalities. In a recent interview with Construction Executive, Carter discusses why the industry must move beyond incremental improvements, how technology and AI can support better planning and what it will take to create a true culture of psychological safety on jobsites.

Can Anything Supersede Excel in AEC?

April 27, 2026 — Aarni Heiskanen - AEC Business
If there’s one piece of software that dominates the business world across industries, it’s Microsoft Excel. Can AI finally dethrone the mighty spreadsheet? Memorable Spreadsheet Moments Everyone has memorable spreadsheet moments. I have a few. For example, my then-architecture firm was involved in more than a dozen housing developments abroad. I developed an Excel workbook that took the required number of households as input and automatically generated a breakdown of buildings and their apartment types for AutoCAD. This was urban planning and architectural design done with a spreadsheet. I also developed business software using Excel for project portfolio management. The prototype was later scaled into a commercial SaaS that is now used globally. Another memorable moment was when a property owner told me their Excel file grew so large that it ran out of rows and columns. That must have been before 2007, when the maximum number of columns on a sheet was still just 256 and the maximum number of rows was 65,536. The current limits are 1,048,576 rows and 16,384 columns, which I hope no one will exceed. Read the full story...

Doctrine of Substantial Performance When It Comes to Payment

July 27, 2026 — David Adelstein - Florida Construction Legal Updates
A recent non-construction case touches upon the doctrine of substantial performance when it comes to payment. In this case, a club was to make two payments to secure a rapper’s attendance. The first payment was made. The second payment was made but was a few hundred dollars short of the agreed amount. The rapper did not show up. The club claimed it substantially performed its obligations. At first glance, the argument makes sense because the second payment fell only a few hundred dollars short. But that wasn’t the case when it comes to pre-commencement payment obligations:

Substantial performance applies only when the variance from the contract terms “is inadvertent or unintentional and unimportant so that the work actually performed is substantially what was called for in the contract.” However, when one party agrees to pay the other on or before a specific date, time is of the essence, and the payor is required to pay the payee on or before that date. “There is almost always no such thing as ‘substantial performance’ of payment between commercial parties when the duty is simply the general one to pay. Payment is either made in the amount and on the date due, or it is not.”

Big Gate Records, LLC v. Washington, 51 Fla.L.Weekly D1281a (Fla. 2nd DCA 2026) (internal citations omitted).

Predict Risk, Not Incidents: A New Analytics Framework for Your Construction Safety Data

August 03, 2026 — Tabrez Zahoor - Construction Executive
Behind every “zero-incidents” company report, hidden hazards may already be accumulating—risks that could become serious injuries tomorrow. The question every executive should be asking is not, “Did anything go wrong last month?” It is: “Where is risk building on my projects right now?” Most construction organizations cannot answer that question. Not because the data does not exist—it does. Every active project generates daily inspection findings, labor records, near-miss reports and audit results. The problem is that standard safety systems collect this data and then report it in ways that make it operationally useless for prevention. They describe the past. They predict nothing. The predictive safety analytics framework (PSAF) is a practical, deployable system developed from years of applying data science to large-scale construction portfolio operations that takes the safety data construction organizations already collect and transforms it into a forward-looking risk signal. The result? A single weekly score that tells executives where risk is concentrating across their portfolio before anyone gets hurt.

Colorado Court Affirms Attorneys’ Fee Award Against Plaintiff’s Counsel for Pursuing Unsupported CCPA Claims

August 03, 2026 — David McLain - Colorado Construction Litigation Blog
The Colorado Court of Appeals recently affirmed a trial court’s award of more than $241,000 in attorney fees against a plaintiffs’ attorney who continued to pursue unsupported claims arising out of a residential construction dispute. Although the opinion was not selected for official publication under C.A.R. 35(e) and therefore has no precedential value, it nevertheless provides an instructive reminder that Colorado courts are willing to impose significant financial consequences when claims lack substantial justification. For builders, developers, contractors, insurers, and defense counsel, the case is worth reading, not because it announces new law, but because it demonstrates that Colorado’s fee-shifting statute remains a meaningful tool when unsupported claims continue long after they should have been abandoned.

The AI Knows Too Much: When Employees Feed Trade Secrets into Generative AI Tools

April 14, 2026 — Kazim A. Naqvi & John V. Mysliwiec - Sheppard
Every time an employee pastes proprietary source code, a customer list, or a confidential business strategy into ChatGPT, Claude, or Google Gemini, they may be quietly dismantling the legal protections that make those secrets worth protecting. Courts and regulators are only beginning to grapple with this problem, and right now, the burden of preventing it falls squarely on employers. The Legal Stakes Under the federal Defend Trade Secrets Act (“DTSA”) and the Uniform Trade Secrets Act (“UTSA”) as adopted across most states, a trade secret plaintiff must show that the information at issue was subject to reasonable measures to maintain its secrecy. Courts have historically credited measures like confidentiality agreements, physical access controls, and employee training—but those safeguards were designed for a world of thumb drives and disgruntled employees. They were not built for a world where a well-meaning engineer can, in seconds, transmit an entire corpus of proprietary data to a third-party AI platform operating under terms of service that may permit the provider to use inputs for model training.
