The　latest　3D　laser　scanning　technology　is　implemented　in　a　practical　project—2022　Beijing　Winter　Olympic　Speed　Skating　Stadium—to　investigate　its　effectiveness　on　the　large-scale　as-built　surveying　of　civil　infrastructures.　The　laser　scanning　was　used　for　measuring　the　vertical　deformation　of　flexible　orthotropic　cable　net　roof　structure　and　for　assessing　the　installation　tolerance　of　curved　glass　curtain　wall　system.　It　was　observed　that　66%　of　clamps　in　the　flexible　roof　structure　showed　vertical　deviations　within　the　range　of　±5　mm　and　94%　of　clamps　showed　deviations　within　±10　mm.　Additionally,　about　60%　of　the　vertical　joints　in　transparent　glass　curtain　wall　showed　deviations　within　the　range　of　±10　mm　and　the　overall　median　deviation　was　only　2　mm.　Given　the　complex　structural　form　of　the　cable　net　roof　structure　and　the　glass　curtain　wall　system,　3D　laser　scanning　demonstrated　unparalleled　efficiency　as　compared　to　the　conventional　measuring　methods.　©　2022　Elsevier　Ltd
