      BIM是什么,有哪些價值作用?

      【摘要】建立以BIM應用為載體的項目管理信息化,提升項目生產效率、提高建筑質量、縮短工期、降低建造成本。

        建筑信息模型(Building Information Modeling)是以建筑工程項目的各項相關信息數據作為模型的基礎,進行建筑模型的建立,通過數字信息仿真模擬建筑物所具有的真實信息。它具有可視化,協調性,模擬性,優化性和可出圖性五大特點。

        建立以BIM應用為載體的項目管理信息化,提升項目生產效率、提高建筑質量、縮短工期、降低建造成本。具體體現在:

        三維渲染,宣傳展示

        三維渲染動畫,給人以真實感和直接的視覺沖擊。建好的BIM模型可以作為二次渲染開發的模型基礎,大大提高了三維渲染效果的精度與效率,給業主更為直觀的宣傳介紹,提升中標幾率。

        快速算量,精度提升

        BIM數據庫的創建,通過建立5D關聯數據庫,可以準確快速計算工程量,提升施工預算的精度與效率。由于BIM數據庫的數據粒度達到構件級,可以快速提供支撐項目各條線管理所需的數據信息,有效提升施工管理效率。BIM技術能自動計算工程實物量,這個屬于較傳統的算量軟件的功能,在國內此項應用案例非常多。

        精確計劃,減少浪費

        施工企業精細化管理很難實現的根本原因在于海量的工程數據,無法快速準確獲取以支持資源計劃,致使經驗主義盛行。而BIM的出現可以讓相關管理條線快速準確地獲得工程基礎數據,為施工企業制定精確人材計劃提供有效支撐,大大減少了資源、物流和倉儲環節的浪費,為實現限額領料、消耗控制提供技術支撐。

        多算對比,有效管控

        管理的支撐是數據,項目管理的基礎就是工程基礎數據的管理,及時、準確地獲取相關工程數據就是項目管理的核心競爭力。BIM數據庫可以實現任一時點上工程基礎信息的快速獲取,通過合同、計劃與實際施工的消耗量、分項單價、分項合價等數據的多算對比,可以有效了解項目運營是盈是虧,消耗量有無超標,進貨分包單價有無失控等等問題,實現對項目成本風險的有效管控。

        虛擬施工,有效協同

        三維可視化功能再加上時間維度,可以進行虛擬施工。隨時隨地直觀快速地將施工計劃與實際進展進行對比,同時進行有效協同,施工方、監理方、甚至非工程行業出身的業主領導都對工程項目的各種問題和情況了如指掌。這樣通過BIM技術結合施工方案、施工模擬和現場視頻監測,大大減少建筑質量問題、安全問題,減少返工和整改。

        碰撞檢查,減少返工

        BIM最直觀的特點在于三維可視化,利用BIM的三維技術在前期可以進行碰撞檢查,優化工程設計,減少在建筑施工階段可能存在的錯誤損失和返工的可能性,而且優化凈空,優化管線排布方案。最后施工人員可以利用碰撞優化后的三維管線方案,進行施工交底、施工模擬,提高施工質量,同時也提高了與業主溝通的能力。

        沖突調用,決策支持

        BIM數據庫中的數據具有可計量(computable)的特點,大量工程相關的信息可以為工程提供數據后臺的巨大支撐。BIM中的項目基礎數據可以在各管理部門進行協同和共享,工程量信息可以根據時空維度、構件類型等進行匯總、拆分、對比分析等,保證工程基礎數據及時、準確地提供,為決策者制訂工程造價項目群管理、進度款管理等方面的決策提供依據。
