Market Size Research for Construction

Published reports are typically based on producer shipment data, which includes inventory movements and does not reflect installed volumes. They use product definitions that rarely match your specific category precisely. They are rarely granular enough for brand share or channel split analysis at the level your strategy requires. Primary research gives you market size defined exactly as your business uses it – your product format, your customer type, your distribution channel – not a proxy from a different data source.

We use a bottom-up approach. We survey a representative sample of contractors, installers, or specifiers and ask about their actual purchase volumes in the past 12 months by product category and brand. We gross up to the market level using active contractor population data from national trade registries, adjusted for company size distribution. We cross-validate against top-down sources – trade association data, construction output statistics, import/export figures – and document where they align and where they diverge.

Sample size depends on output granularity. For a single-country study requiring national-level estimates by product category, 100-200 contractor interviews is typically sufficient. For multi-country studies or studies requiring regional breakdowns, 200-300 interviews per country may be needed. We provide confidence intervals on all estimates rather than single-point figures, and we recommend the minimum sample that makes the outputs statistically defensible for your specific use case.

Yes. Many construction clients run annual sizing waves to track share movement and validate the effect of product launches or pricing changes. We maintain consistent methodology between waves so trend lines are valid. We document all methodology parameters between waves and flag any changes in market structure that affect comparability.

Yes. We have sized construction markets in the United States, Canada, the Middle East, and Asia-Pacific. Methodology adapts to local market structures – in some markets, trade distribution data is more accessible through associations; in others, contractor-level phone interviewing is the only reliable source. We advise on the most practical approach for each specific market before committing to a design.

We recruit by phone. In markets where phone recruitment is more challenging – some emerging markets, or highly fragmented contractor populations – we supplement with face-to-face interviewing or use established local fieldwork partners with professional trade networks. We do not substitute with online panels for volume estimation purposes. Panel data quality for professional volume reporting is not adequate.

Yes, and we have run studies specifically designed for this use. For M&A contexts, we provide a full methodology appendix documenting the sample design, weighting approach, validation process, and confidence intervals. The appendix is structured to withstand scrutiny from a financial or legal team. We provide point estimates and ranges, not single figures presented without margin of error.
