Methodology and sourcing behind the figures shown above.
Delay and critical-path analysis
No explicit market-size figures were found in the supplied results. Using the search results to define scope (construction/project-controls, CPM and delay-analysis tools and consulting) and internal market hierarchy, I estimated a niche global market (~$1B) combining software, schedule-forensics tools, and professional claims/delay-analysis services. Assumptions: delay/critical-path analysis represents a small subset of the broader project-management and construction-software markets (single-digit percent), with digitization, increased dispute activity, and uptake of automated scheduling/AI driving mid-high single-digit CAGR.
Quantum and claims valuation
Search results primarily report quantum computing market sizes and CAGRs (cited below) but contain no data on the niche “claims valuation” or insurance-claims advisory services. Because the provided results do not quantify the market for claims valuation services, I cannot reliably estimate market size or CAGR for that specific segment without additional, relevant sources.
- The global quantum computing market size was valued at USD 1.39 billion in 2025; projected to USD 17.89 billion by 2034, CAGR of 33.0%.
- In 2025 the global quantum technology industry reached $1.9 billion; quantum computing $1.4 billion; projected to reach $3 billion by 2028.
- MarketsandMarkets: quantum computing market valued at USD 3.52 billion in 2025 and projected to USD 20.20 billion by 2030, CAGR 41.8% (2025–2030).
- PersistenceMarketResearch: global quantum computing market valued at US$ 698.6 million in 2026; projected US$ 1,716.1 million by 2033, CAGR 13.7% (2026–2033).
Expert witness and litigation support
Estimates prioritize specialist expert-witness market reports in the search results. Two focused reports place the expert-witness market below $1B (US$0.713B in 2024; ~US$0.82B in 2026). Wider categories (litigation consulting) are much larger (tens of billions) and reflect adjacent services. I adopt a conservative point estimate ~USD 0.8B (specialist expert-witness services) and a moderate CAGR (~6.4%) consistent with multiple sector reports and the mid-range of cited projections.
- The global expert witness services market is valued at approximately USD 0.82 Billion in 2026 and is projected to reach USD 1.91 Billion by 2035; CAGR around 11%.
- Valued at US$ 713 million in 2024; forecast to reach US$ 1033 million by 2030, at a CAGR of 6.4%.
- was valued at USD 6.44 Billion in 20025 and is projected to reach USD 10.99 Billion by 2035, growing at a CAGR of 5.5% from 2027 to 2035.
- Industry Size (2025): USD 61.3 Bn; Forecast (2035): USD 104.7 Bn; CAGR (2025 to 2035): 5.5%.
Forensic engineering and root cause investigation
Primary sources in the search results cluster around a global market size of roughly $5.1–$5.4B for 2023–2025 (Credence, GMI, Data Insights). Credence Research explicitly reports USD 5.25B in 2024 with a 6.0% CAGR; GM Insights and Data Insights report ~USD 5.1–5.4B and ~5% CAGR. One provider (Business Research Insights) projects a higher figure and ~8% CAGR; to reflect the consensus and outlier variation, the estimate uses Credence’s 2024 figure (USD 5.25B) and a midpoint CAGR (~5.5%).
- Forensic Engineering Services Market Size 2024 USD 5,250 million … CAGR 6.0%.
- Market size was valued at USD 5.1 billion in 2023; CAGR over 5% (2024–2032).
- Valued at $5.4 Billion in 2025; projected to grow at a CAGR of 5% through 2033.
