Deal Spotlights
Construction Consulting Associates Joins Aperture LLC
Aperture LLC , the Genstar Capital -backed national forensic expert platform headquartered in Arlington, Texas, has welcomed CCA Construction Consulting Associates (CCA) into its growing portfolio. CCA is a multi-disciplinary forensic engineering and construction consulting firm with deep expertise in structural, mechanical, architectural, and environmental health and safety investigations. The firm serves public, private, and government entities on everything from construction defect investigations and delay analysis to litigation support and project management across the full building lifecycle.
CCA brings decades of forensic work across building envelope failures, construction defects, indoor health claims, and complex delay disputes, complementing Aperture’s existing strength in accident reconstruction, premises liability, and economic damages.
This acquisition marks Aperture’s continued execution under Genstar Capital following the private equity firm’s majority investment in January 2025 and a string of subsequent add-ons, including Bryant Consultants, geotechnical, September 2025, and a new Tampa office opening, October 2025.
Axiom Joins Salas O’Brien
Axiom, a structural engineering firm with a distinctive focus on Integrated Steel Delivery (ISD) and collaborative digital design, has joined Salas O’Brien. The firm specialises in structural design and engineering, project development services, and a proprietary ISD model that enables design, procurement, and construction to run simultaneously in a shared digital environment, significantly compressing project timelines and improving cost certainty for clients.
Axiom serves clients across commercial, education, government, healthcare, industrial, modular, and multi-family markets, with a reputation for simplifying complex structural challenges and delivering speed without sacrificing design integrity. The firm’s offices and leadership team remain in place under the Salas O’Brien platform.
Axiom’s clients can expect the same team and level of service, with the added reach and resources of Salas O’Brien’s national engineering platform behind them.
RPM International Completes Kalzip Acquisition
RPM International has completed its acquisition of Kalzip GmbH, a globally recognised leader in aluminium roofing and façade systems, integrating the German firm into its Tremco Construction Products Group. Kalzip, headquartered in Koblenz, specialises in customised lightweight, weather-resistant building envelope technologies and has delivered over 1.2 billion square feet of aluminium solutions worldwide, with landmark projects including the Estadio Santiago Bernabéu in Madrid and the LAX Train Station in Los Angeles.
The Bottom Line:
The pace of consolidation is accelerating across every layer of the built environment sector, from forensic expert platforms to MEP engineering networks to building products manufacturers. Firms with strong technical leadership, recurring institutional revenue, and defensible specialist expertise will continue to command premium attention from both strategic and financial acquirers throughout 2026.

YA Group Launches Forensic Accounting Practice
In a significant service line expansion, YA Group , an international leader in building consulting and forensic engineering, announced the launch of a dedicated Forensic Accounting group in March 2026. The new practice is anchored by a team of professionals joining from LFI Forensic Accounting, a globally recognised financial investigations firm, and adds insurance claims accounting, fraud investigation, corporate compliance, and financial dispute services to YA’s existing forensic engineering and litigation advisory capabilities.
Construction Disputes | Geopolitical Headwinds Return
Global construction markets are again feeling the strain of geopolitical shocks echoing through supply chains, according to a recent HKA analysis published in April 2026. Rising material costs continue to compress contractor margins, increasing the volume and complexity of delay and disruption claims reaching forensic engineers.
Spotlight | Defensibility in Forensic Engineering Reports
The Shift
Across the built environment, forensic engineering is facing increasing scrutiny on the defensibility and transparency of conclusions used in high-value insurance and litigation contexts.
Regulators such as the Florida Board of Professional Engineers and industry stakeholders are placing greater emphasis on how engineering opinions are formed, documented, and supported. The focus is shifting from what engineers conclude to how they arrive there.
The Pressure Points
Several trends are driving this shift:
- Increased dispute volume in property insurance claims, particularly following extreme weather events
- Greater legal scrutiny of methodology, assumptions, and documentation
- Growing use of peer review and expert challenges in litigation
- Concerns around inconsistent reporting standards across firms and regions
The Response
Leading firms are evolving how they structure and deliver forensic work:
- Standardising report formats to clearly link observations → analysis → conclusions
- Explicitly referencing codes, standards, and testing methodologies
- Incorporating photographic, laboratory, and field data as core evidence
- Implementing internal technical peer review processes before report issuance
- Leveraging digital tools to improve traceability and documentation consistency
The Opportunity
As scrutiny increases, so does the opportunity for differentiation.
Firms that can deliver highly defensible, well-documented, and transparent assessments are:
- More credible in litigation
- More trusted by insurers and asset owners
- Better positioned to command premium fees
Beyond dispute resolution, this capability is also opening doors into:
- Pre-loss risk advisory
- Portfolio-level condition assessments
- Strategic asset management consulting
The Bottom Line
Forensic engineering is evolving from reactive investigation to evidence-led risk intelligence. In a market where conclusions are increasingly challenged, the firms that win will be those that can not only diagnose failure, but prove it, defend it, and stand behind it under scrutiny.
Regulatory Watch
NYC Local Law 97
New York City’s Local Law 97 carbon emissions enforcement enters a critical enforcement phase in Q2 2026, with building owners facing financial penalties for non-compliant buildings. Demand for envelope retrofit consulting, particularly thermal performance upgrades, façade air-sealing, and high-performance glazing, is expected to surge as owners exhaust exemption options and seek engineering solutions to achieve compliance ahead of escalating penalty tiers.
ASTM Building Envelope Testing Standard Updates
ASTM updates to E1105, field testing of water penetration, and E2128, evaluating water leakage in building walls, with potential implications for how firms certify waterproofing performance and air barrier continuity on both new construction and forensic investigation projects. Enclosure consultants should begin reviewing current testing protocols against anticipated revised criteria.
Market Trend
AI-Powered Predictive Maintenance Entering Beta
Several platforms offering AI-driven structural risk scoring and building condition monitoring are emerging across the AEC and property sectors, reflecting a broader shift toward predictive maintenance and data-driven asset management.
These tools aim to move a portion of forensic work from reactive failure investigation toward proactive risk assessment and continuous monitoring. While widespread adoption remains a medium-term horizon, early movers in the forensic and enclosure consulting space are beginning to evaluate how these technologies can extend their service offering into asset management and portfolio risk advisory.
