From Dark Data to Building Intelligence

July 13, 2026 — Aarni Heiskanen - AEC Business
In this episode, I talk with Mark Sorsa-Leslie, founder and CEO of Auttaa AI, whose team just won first place in Luotea’s inaugural hackathon in Helsinki for turning property maintenance from reactive firefighting into proactive forecasting with AI. Mark is a chartered surveyor with 30 years of real estate data experience, previously the founder of the UK sensor company Beringar. We discuss why so much building data stays dark and siloed, from outdated networking technology to the shortage of people who understand both engineering and property. Mark explains how Auttaa bridges real-time building data with large language models, using what he calls an “influence graph” to surface correlations and causation across previously disconnected systems, such as linking occupancy patterns to CO2 readings to diagnose ventilation problems in minutes rather than days.

A Green Light for Housing? What Executive Order 14394 Means for Your Next Project

May 26, 2026 — Bennett Houck, Miranda Martinez & Byron Sarhangian - Snell & Wilmer
On March 13, 2026, President Trump signed Executive Order 14394, “Removing Regulatory Barriers to Affordable Home Construction” (the “Order”). The Order directs federal agencies to reduce regulatory burdens on residential development, streamline environmental permitting, and encourage state and local governments to adopt housing-friendly policies. The Order includes several key provisions that developers and homebuilders should be aware of moving forward. Key Provisions The Order targets four main areas: 1. Federal Environmental Regulations First, it directs the Secretary of the Army and Environmental Protection Agency (EPA) to revise permitting standards, including stormwater permits, wetlands permits under Section 404 of the Clean Water Act, and related construction-site requirements. The Order also targets energy-efficiency mandates for U.S. Department of Housing and Urban Development (HUD) and U.S. Department of Agriculture (USDA) financed housing. For developers and homebuilders, these revisions could reduce project delays and compliance costs associated with stormwater management, wetlands mitigation, and energy-efficiency upgrades, expenses that often add significant time and cost to residential development projects.

Achieving Sustainability Through Design Build Delivery: Part II – A Framework for Managing Sustainability Objectives on Private Commercial Construction

October 06, 2026 — Jennifer Harris, Tiffany Harrod & Joshua Pruett - ConsensusDocs
Part I of this series traced the history and development of sustainability in construction and explained why design-build (“DB”) contracting is particularly well suited to achieve sustainability objectives. But selecting DB contracting does not by itself ensure a sustainable outcome. The parties must define their sustainability objectives with precision, establish measurable performance criteria and identify who will measure compliance with the criteria, and also draft contract terms that clearly and fairly allocate the associated responsibilities and risks. Otherwise, the completed project may fall short of its sustainability objectives and expose the parties to claims, disputes, and litigation. Part II offers a non-exhaustive list of practical guidance for addressing these issues and reducing those risks. This article references the ConsensusDocs 310 Green Building Addendum, in conjunction with an agreement between the Owner and the Design-Builder (e.g., ConsensusDocs 415)[1], [2] and AIA Document E204–2017 Sustainable Projects Exhibit,[3] together with AIA A141,[4] as its contractual baseline. The five-part framework that follows is a roadmap for allocating sustainability risk between private owners and design-builders: define the requirements, identify hidden performance guarantees, map out the sustainable objective, address third-party certification risk, and track performance against agreed benchmarks.

USDOT’s DBE Interim Final Rule: How It Affects Current and Out-to-Bid DOT and Airport Projects

June 15, 2026 — Zachary F. Jacobson - The Construction Seyt
In our April 16, 2026 post, we discussed the U.S. Department of Transportation’s Interim Final Rule (IFR) concerning Disadvantaged Business Enterprise (DBE) and Airport Concession Disadvantaged Business Enterprise (ACDBE) certification, specifically as it concerns transportation and airport projects in California. This post addresses a broader question: What does the IFR mean for current and out-to-bid DOT projects operating under pre-existing DBE goals? The answer is that the IFR did more than change who qualifies as a DBE. It also changed how federally funded transportation and airport projects must be handled during the re-evaluation period. This affects active contracts, pending procurements, airport projects, design-build teams, and anyone relying on old assumptions about DBE goals and counting of DBE and ACDBE credit.

The Deadline to File Suit on a Public Works Payment Payment Bond is Triggered by a Claimant’s Work on a Project Not by a Claimant’s Work Under a Contract

June 02, 2026 — Garret D. Murai - California Construction Law Blog
California law requires that prime contractors furnish a payment bond – providing for payment to lower-tiered subcontractors and suppliers – on state and local public works projects with a value in excess of $25,000. There are three conditions that must be satisfied when a claimant makes a claim against a payment bond on a public works project in California:

First, generally, the claimant must have served a preliminary notice, unless the claimant is a first-tier subcontractor or supplier;
The claimant must have “ceased to provide work” on the project; and
The claimant must file suit against the payment bond no later than six (6) months after the period in which a stop payment notice must be given or, in other words, the earlier of 270 days after completion of the public works project or 210 days after a notice of completion or cessation was recorded on a public works project.

In Tarlton & Sons, Inc. v. Great American Insurance Company, 111 Cal.App.5th 376 (2025), the 2nd District Court of Appeal examined whether a subcontractor timely filed a claim against a payment bond when a prime contractor was terminated and replaced by another prime contractor who the subcontractor continued to perform work for.
