Moving in Before Substantial Completion? The Risks of Early Owner Occupancy

March 24, 2026 — Sydney Koby - ConsensusDocs
Introduction On many construction projects, particularly large projects facing schedule pressure, owners may begin occupying or using portions of the project before the work reaches substantial completion. This is often due to operational needs, phased turnover, or market demands that drive owners to take possession of all or part of a project while construction activities are ongoing. While early occupancy may seem practical, it can blur the lines of responsibility between owner and contractor and can create significant legal and practical complications. These disputes are especially common on large, complex projects where punch list work, system commissioning, and closeout activities overlap with owner use. Without clear documentation and carefully drafted contract provisions, early occupancy can undermine an owner’s ability to enforce completion requirements while simultaneously exposing the contractor to claims of delay, inefficiency, or interference.

Reducing Rework on Construction Projects Benefits Budget, Schedule and Financial Loss

February 10, 2026 — Brian Clarke - Construction Executive
The costs of not building it right the first time is statistically staggering—some research suggests up to 20% of the total project costs. This article highlights the costs of re-work, provides a financial worksheet to track the costs of re-work, and a trusted tool to help reduce the impact of re-work. Typically, when discussing rework, one thinks of the labor and material costs, but there are other costs associated with rework that are less easily quantified:

• Liquidated damages and related legal costs
• Potential for increasing safety incidents associated with rework
• Morale loss due to performing rework
• Loss of previously trained workers due to delays caused by rework
• Reputational loss and the inability to bid on future work
• Challenges of future work to be performed due to schedule delays on a current project

How to Properly Fill Out and Use the Unconditional Waiver and Release on Final Payment Form Used in California Construction

January 05, 2026 — William L. Porter - Porter Law Group
This is the fourth article in a series of four articles discussing how to properly fill out the four California construction releases described in California Civil Code 8132 – 8138. Let me start by noting that in addition to practicing construction law for more than 35 years, I chaired the committee of California construction attorneys who revised those sections of the California Civil Code dealing with this release form and many other construction forms as part of Senate Bill 189 in 2010. I also wrote the first version of this release form and made it free to the public well before the new law took effect in 2012. With this background, let me note a few things about the Unconditional Waiver and Release on Progress Payment form to help you avoid mistakes that might prevent you from achieving the intended effect of the form or releasing claim rights to a greater extent than you intend.

Top Developments 2025 - Issue 4

December 22, 2025 — John S. Anooshian, Paul A. Briganti, Elizabeth L. Ferguson, Alexandra M. George & Haley S. Newman - The Complex Insurance Coverage Reporter
“ARISING OUT OF” Rowe v. State Mut. Ins. Co., 2025 Me. LEXIS 89 (Me., Sept. 23, 2025) Maine Supreme Court, in the premises liability context, holds that an exclusion in a mobile homeowners policy for injury or damage "arising out of a premises . . . that is not an insured location'” precluded coverage for underlying negligent failure-to-warn claims. The court looked to authority from a workers compensation case, where it stated that “the term ‘arising out of' employment means that there must be some causal connection between the conditions under which the employee worked and the injury, or that the injury, in some proximate way, had its origin, its source, or its cause in the employment. . . . [T]he employment need not be the sole or predominant causal factor for the injury and . . . the causative circumstance need not have been foreseen or expected.” In this case, it found there to be “an immediate relationship between the injury and a condition of the uninsured premises” (specifically, a gap created by the owner-insured at the entrance to a mobile home), and rejected the claimant’s argument that the injury instead arose from the insureds’ negligent conduct in failing to warn. Separately, the court held that the property did not qualify as an “insured location,” reasoning it was not listed in the declarations and there was no evidence the insureds had resided there or acquired it for use as a residence.

The court refused to dismiss the insured’s claim for hail damage based on late notice because the insurer failed to demonstrate it had suffered prejudice. Borene UMC v. Church Mut. Ins.

Are Robotic Coworkers Soon a Reality in Construction?

March 24, 2026 — Aarni Heiskanen - AEC Business
General-purpose humanoid robots are in the headlines, but is the hype justified? What’s the point of having a robot home assistant when it still needs a “guy behind the curtain” to control it remotely? Despite the challenges, robots, even those that look like humans, are seriously considered as future coworkers in business environments. According to the McKinsey report ‘Will embodied AI create robotic coworkers?‘ the idea that AI-powered robots will become general-purpose coworkers is grounded in real technological progress, but not an overnight reality.
