SCB EIC forecasts public construction value in the 2027 fiscal year at about 927,000 million baht, down 5%, after the investment budget falls 13%. Private construction is flat at about 598,000 million baht, with housing and office/retail falling while factories and data centres hold up. Building materials demand will stay low and prices may ease, but cheap imported steel and tiles are a threat. Contractors should favour cash flow and backlog discipline, avoid price-war bids, and lock in material supply in advance. Material makers should watch import competition and CBAM costs on steel exports.
