Construction Robotics Works Where Variation Ends

August 11, 2026 — Aarni Heiskanen - AEC Business
BuiltWorlds published its 2026 Robotics Top 50 this summer, and the list is genuinely wide. Fifty solutions across nine categories, from 3D printing and prefabricated component manufacturing to earthmoving, demolition, material transport, layout, installation, inspection, and drilling. The honorees come from sixteen countries. It looks like robotics has finally spread across the whole project lifecycle. However, having vendors in nine categories does not mean that contractors are robotizing their work en masse. Zacua Ventures, in its 2026 construction robotics report, estimates that on-site robotics accounted for less than 0.03% of global construction spending in 2025. Zacua says: “That is not a failed market. It is a market at the beginning of an adoption S-curve”, while warning that its estimates rest on private vendor data and may be high if vendors overstate how widely their machines are deployed.

Inaccurate Representations Can Lead to Differing Site Conditions Claim

May 26, 2026 — David Adelstein - Florida Construction Legal Updates
In the prior posting, I discussed a case dealing with a differing site condition. In that case, the owner did not have an affirmative duty to make a representation and there was no inaccurate representation made by the owner that misled the contractor. Well, what about when there is an inaccurate misrepresentation regarding the site? This was the circumstance in an older Florida case where a dredging contractor had a successful differing site conditions claim. See Jacksonville Port Authority v. Parkhill-Goodloe, Co., Inc., 362 So.2d 1009 (Fla. 1st DCA 1978). The government provided inaccurate information as to the lack of rock that would be encountered during the dredging that was relied on by the dredging contractor. But the government had “superior knowledge” that there was rock in an adjacent location based on a prior claim from a contractor, yet the government did not disclose the possibility that rock could be encountered.

Voluntary Dismissal of an Indemnity Claim Does Not Make the Subcontractor a “Prevailing Party,” Washington Court of Appeals Holds

September 21, 2026 — Margarita Kutsin - Ahlers Cressman & Sleight PLLC
In King County v. Walsh Construction Company II, LLC, No. 86503-0-I (Wash. Ct. App. Aug. 4, 2025), an unpublished decision from Division I of the Washington Court of Appeals, the Court affirmed the denial of a subcontractor’s request for prevailing-party attorney fees under an indemnity clause after the general contractor voluntarily dismissed its indemnity claims. Because the indemnity claim was no longer live and no determination of fault had occurred, the Court held that the trial court did not err in denying the request. ACS represented Walsh, the general contractor, in securing the denial of the fee request at the trial court that the Court of Appeals affirmed. A Pass-Through Indemnity Claim That Ended Before Fault Was Decided The dispute arose out of a public works contract under which King County hired Walsh Construction Company II, LLC (“Walsh”) to construct and install a conveyance pipeline. After the pipeline broke, King County sued Walsh for breach of contract and warranty, expressly identifying both Walsh and its subcontractor, Mears Group Inc., (“Mears”) as responsible. Walsh tendered defense and indemnity to Mears under the subcontract. Read the full story...
