The　cast-in-situ　reinforced　concrete　grillage　shear　wall　system　with　non-dismantling　formwork　is　a　new　type　of　structural　system　characterized　by　load-bearing　and　thermal　insulation,　and　the　research　on　the　construction　technique　is　crucial　to　its　promotion　and　application.　Combined　with　the　pilot　building,　the　key　technology　and　construction　measures　are　introduced　in　this　paper,　which　can　provide　reference　for　the　related　projects　in　future.
