產業新聞BIM如何降造價—施工階段篇

BIM技術的發展與成熟,給工程項目提供了強大的降低工程造價成本的技術手段。本文從BIM在施工階段的降低工程造價工作實現方法為大家普及BIM技術在工程造價管理上的應用

 

施工階段

1.動態成本分析

將包含成本信息、進度信息的BIM模型上傳到系統服務器,系統就會自動對模型進行解析,將成本數據進行分類和整理,形成多維度圖形的成本數據庫。


2.人材機分析

2.1.材料計劃

將施工BIM模型導入造價軟件後,可以分析出所需要的人材機計劃量。這些計劃量根據施工經驗去掉一定折扣後,可以作為材料用量計劃和採購申請的依據。

2.2.多算對比

施工過程中通過短週期的多算對比,可以及時掌握項目動態進展、快速發現並解決問題。

目前的施工項目上普遍使用是前期計劃量和施工過程中實際量對比。可以按照施工區域進行時間對比,也可以按照施工進度進行對比。如果需要按照時間對比,需在前期預算BIM模型和施工過程中的施工BIM模型增加時間維度。前者按照計劃時間設定,後者按照實際時間調整。

 


3.限額領料

限額領料目前最大的問題在於無法及時獲知領料數據,BIM為限額領料提供了技術及數據支撐,倉管人員可在BIM系統中快速檢索相應施工區域的材料用量

 


4.快速實現設計變更

BIM在設計變更管理中最大的價值不是輸理清楚變更的流程,而是最大限度的減少設計變更,從而從源頭減少變更帶來的工期和成本的增加。

 


5.快速實現進度款支付管理

建築信息目前主要是基於2D-CAD圖紙建立的,工程基礎數據掌握在分散的預算員手上,很難建立數據對接,導致工程造價快速拆分難以實現,工程進度款的申請和支付結算工作也較為繁瑣。

在進度款結算方面,BIM軟件實現了框圖出價、框圖出量、更加快速地完成工程量拆分和重新匯總,形??成造價文件,為工程進度款結算工作提供技術支持
