      BIM技術在企業中標率中起到關鍵性作用

      【摘要】怎樣才能提升項目的中標概率呢?如何在投標階段為項目“盈利”打好基礎呢?

        如今,建筑行業新開工項目大幅縮減,僧多粥少的局面下施工單位中標越來越難。即使中標,項目利潤也難以得到保證。那么,怎樣才能提升項目的中標概率呢?如何在投標階段為項目“盈利”打好基礎呢?

        BIM技術將是施工企業提升投標概率,清楚項目潛在利潤的重要技術。隨著BIM熱潮的掀起,業主對BIM的認知與認可度越來越高,如SOHO、萬達等業主,上海中心、上海迪斯尼等項目就將施工過程中應用BIM技術作為必要條件寫進招標合同。

        BIM在招標控制中的應用

        在招標控制環節,準確和全面的工程量清單是核心關鍵。而工程量計算是招投標階段耗費時間和精力最多的重要工作。BIM是一個富含工程信息的數據庫,可以真實地提供工程量計算所需要的物理和空間信息。借助這些信息,計算機可以快速對各種構件進行統計分析,從而大大減少根據圖紙統計工程量帶來的繁瑣的人工操作和潛在錯誤,在效率和準確性上得到顯著提高。

        (1) 建立或復用設計階段的BIM模型

        在招投標階段,各專業的BIM模型建立是BIM應用的重要基礎工作。模型的建立主要有三種途徑:

        1.直接按照施工圖紙重新建立BIM模型,這也是最基礎、最常用的方式。

        2.如果可以得到二維施工圖的AutoCAD格式的電子文件,利用軟件提供的識圖轉圖功能,將dwg二維圖轉成BIM模型。

        3.復用和導入設計軟件提供的BIM模型,生成BIM算量模型。這是從整個BIM流程來看最合理的方式。

        (2) 基于BIM的快速、精確算量

        基于BIM算量可以大大提高工程量計算的效率。基于BIM的自動化算量方法將人們從手工繁瑣的勞動中解放出來,節省更多時間和精力用于更有價值的工作,如詢價、評估風險等,并可以利用節約的時間編制更精確的預算。

        基于BIM算量提高了工程量計算的準確性。工程量計算是編制工程預算的基礎,但計算過程非常繁瑣,造價工程師容易因各種人為原因而導致很多的計算錯誤。BIM模型是一個存儲項目構件信息的數據庫,可以為造價人員提供造價編制所需的項目構件信息,從而大大減少根據圖紙人工識別構件信息的工作量以及由此引起的潛在錯誤。因此,BIM的自動化算量功能可以使工程量計算工作擺脫人為因素影響,得到更加客觀的數據。
