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...

Breaking Ground On New California Public Works Prevailing Wage Requirements

April 27, 2026 — Heather Frisch, Christopher Bouquet & Ashley Stein - The Construction Seyt
Seyfarth Synopsis: As of January 1, 2026, AB 889 bulldozed California’s Prevailing Wage law, which impacts public works employers—including public agencies, the contractors that work for them, and private owners and developers whose projects may be subject to public works requirements. The amended law reframes the calculation of fringe benefits for individuals who work on public works project and mandates annualization of such benefits, demolishes the practice of frontloading these benefits, and requires employers to maintain inspection-ready records of compliance. This year, AB 889 significantly revised California’s prevailing wage law, codified at Labor Code section 1773.1, to clarify the state’s prevailing wage regulations and streamline enforcement. Accordingly, as of January 1, 2026, California public works employers are required to annualize employees’ fringe benefits and maintain specific documentation demonstrating statutory compliance. These new obligations impact public agencies and their contractors, as well as private owners and developers whose projects may be subject to public works requirements. Continue reading for the blueprint of how to comply with the state’s amended prevailing wage law.

GRSM Secures Illinois Appellate Victory for Architectural Firm in Implied Warranty Dispute

May 14, 2026 — Gordon Rees Scully Mansukhani
Gordon Rees Scully Mansukhani Partner Jonathan Federman, Partner Thomas Cronin, and Senior Counsel Garrett Lee recently secured a victory in the Illinois Appellate Court, Fifth District, on behalf of the firm’s client, an architectural firm, in a liability dispute. The case arose following an entity’s purchase of a 111-unit building for use as an investment or rental property. The plaintiff made claims against the architect of the building, alleging that there were design defects that breached an implied warranty, as well as a negligence claim. GRSM argued that an architect could not be liable for implied warranties, particularly for an implied warranty which no Illinois court has ever recognized. GRSM further argued that Illinois law bars an architect from liability for negligence arising from a duty pursuant to contract under the economic loss doctrine. Read the full story...
