Abstract
<jats:p>This article investigates the standardisation challenges of Building Information Modelling (BIM) processes in the Republic of Kazakhstan within the context of ISO 19650, the international standard governing information management across the full lifecycle of built assets. The study is motivated by Kazakhstan's strategic commitment to digital transformation in construction under the Digital Kazakhstan programme. The methodology combines regulatory analysis of ISO 19650 and Kazakhstani legislation, structured expert interviews with representatives of 15 construction and design organisations, and a comparative BIM standardisation maturity analysis across four jurisdictions — Kazakhstan, the United Kingdom, Russia, and the UAE — using an original assessment matrix based on the BIM Maturity Index model. Content analysis of seven real EIR documents from Kazakhstani public-sector projects (2022–2025) was also conducted. The calculated BIM Standardisation Maturity Index places Kazakhstan at 1.75 out of 5.00 — an initial maturity level — behind the United Kingdom (4.95), the UAE (4.30), and Russia (2.90). Three barrier groups are identified: regulatory — BIM models lack legal status and no national standard exists; organisational — average EIR compliance with ISO 19650-2 was only 18%, and 93% of tender documents contained no BIM requirements; and technological — IFC format incompatibilities and the absence of a state CDE platform. A hybrid BIM ecosystem development strategy targeting a maturity index of 3.50 by 2030 is proposed, prioritising legal recognition of BIM models, adoption of a national standard based on ISO 19650, and establishment of a state CDE platform.</jats:p>
