Methodology and sourcing behind the market figures shown above.

General contracting

Used reported global construction market and subsector reports to triangulate an addressable market for end-to-end general contracting (project management, trades, finish work). StraitsResearch reports the global construction market reaching $3,189.04B by 2034; modular construction (a services-heavy subset) is projected at $85.51B in 2025 growing to $111.75B by 2030 (5.5% CAGR), and utility-system construction is cited at ~$0.87B in 2025 with a ~5.6% CAGR. Near-term spending softness (Gilbane: ~1% growth in 2025) suggests lower short-term growth, so a conservative long‑term CAGR of ~4.5% for global general contracting is estimated, and the market size is approximated at ~$1.0T (roughly 30–35% of the broader construction market).

Construction management (GMP)

Estimate derived from reported global construction services market scale and software-led adoption trends. Global construction services are reported at ~USD 1.33 trillion (2026); assuming construction management/GMP represents roughly 4–8% of total construction services (typical share for professional management and CMAR/CM-at-risk activity), a 6% share yields ~USD 80B. Growth baseline uses the construction services CAGR (5.5%) adjusted upward (~+1–1.5ppt) to reflect stronger adoption of open‑book/GMP delivery, digital project controls, and rising spend on management and software (software CAGRs reported 8–12%), producing an estimated ~7% CAGR for the GMP construction management segment.

Preconstruction planning and estimating

Search results include a focused market estimate for smart construction estimating platforms (USD 1.2B in 2024; 12.5% CAGR). I treat that as a lower bound for digital estimating tools within preconstruction. Preconstruction planning and estimating also includes professional services (consulting, quantity takeoffs, constructability reviews, value engineering) and non-software activities that typically represent several times the software/platform spend. Using the 1.2B platform figure as a floor and applying a conservative 7–10x multiplier to capture global professional services and broader preconstruction activities yields an estimated ~USD 10 billion market in 2024. Growth potential is set below the platform-software CAGR (12.5%) because services adoption and contracting cycles grow more slowly than SaaS/platform adoption; the resulting estimated CAGR is ~7.5% driven by continued digital adoption, rising construction costs, and increasing emphasis on early risk reduction.

Healthcare and senior living construction

Used the provided industry reports: GrowthMarketReports gives a global senior-living construction market size (construction-specific) of USD 56.2B (2024) with a 7.1% CAGR to 2033. Broader senior-living market figures from SLInvestors and NovaOne (USD ~923–944B and ~4–4.5% CAGR) were used as context to confirm construction is a subset of a much larger senior‑living market.
