      BIM技術是如何實現改變工程造價模式的?

      【摘要】現在,不管BIM根據什么規則計算出來的,只要官方認可、行業認可或普遍認可,那么,就沒有爭論的必要,從而省去大量處理爭端的時間。

        自引入BIM后,一些造價人產生了莫名的恐慌,擔心以后BIM慢慢就取代了工程造價,造價人員不再有需求。事實上,造價人是否會被行業淘汰,并非取決于BIM的普及程度,而是取決于造價人在BIM大潮來臨前如何及時轉型。

        BIM確實能減少造價人員的重復勞動。在計算工程量時,每一個造價人出于對圖紙的不同理解和自己的專業水平高低而得到不同的數值,甚至同一個人不同時間計算或使用不同軟件計算,其計算結果也不同。所以,差異是必然的,相同是偶然的,這就增加造價工作無窮的麻煩,如反復的校對、核對、爭論、扯皮等,有時即使雙方確認了甚至簽字了,對方又反悔了,并且確實又找出少算或多算的地方,真的沒完沒了了。

        而工程量又是造價的基礎,算量與對量是造價人日常工作,它是最為重要又最為煩瑣的工作,也是最為枯燥的工作內容。鋼筋、混凝土、裝飾、電纜、管道、閥門,這些造價占比大,是計算的重點和談判的焦點,還有零星,工程量小而工作量大。工程結算工程耗時長,絕大多數時間就是用于此。

        以往,有些爭議性的東西由于沒有標準的計算規則而懸而未決,現在,不管BIM根據什么規則計算出來的,只要官方認可、行業認可或普遍認可,那么,就沒有爭論的必要,從而省去大量處理爭端的時間。個體之間的出于立場的不同難免有傾向性的偏執的觀點,無非是為了爭取到更多的利益。當BIM出現后,這些問題都將迎刃而解。如果BIM計算的量大家都認為有問題,那么就修改BIM的內置計算規則。我不建議計算規則開放,否則,又將輪回到爭議的怪圈內。計量就是要標準化,人是不可信的,要相信機器。

        造價人員從機械的、低端的、煩瑣的工程量計算工作中擺脫出來,可以有更多的時間與精力從事更高端更有價值的咨詢工作。如設計優化、招標策劃、投標對策、合約規劃、成本控制、全過程造價管理等這些技術含量更高的業務,最終形成個人職業生涯的良性循環,而不是被無盡的算量工作所湮沒。

        BIM是可以提供工程量的。BIM對造價專業產生了很大的推動作用,能夠將大量的、重復的、機械的算量工作交給機器去完成,把算量工作從造價工作中分離出去,對造價人是一種解脫。它是基于BIM模型自動完成的工作,BIM模型直接提供標準工程量。算量工作將不復存在,它不再占用造價人大量時間,這是技術的進步,是生產力的解放。設計師代替造價師完成了計算工程量的工作,實際上是BIM工程量計算模塊完成了工程量計算工作,是機器代替了人。

        BIM工程量是基于軟件計算,不受人工干預,如果模型是正確的,計算模塊是正確的,那么計算出來的工程量是沒問題的,無須懷疑它的正確性,更無須用手工來驗算它的合理性。它是一個確定的可信的標準的統一的數據,理論上它是唯一的。它是招投標、預算、材料計劃、成本分析、結算、造價控制等的基礎數據,也是各單位、各條線、各部門、各階段都可共同使用的基礎性數據。這大大減少重復計算,造價人員也將大幅減少。

        一個項目圍繞共同的BIM平臺,參與各方既共享BIM信息,又提供信息。不管BIM是采用哪個系統使用何種軟件,均應以一種軟件提供統一工程量。BIM模型提供的信息可以在全生命周期通用,所有的項目參與方都會依賴這個模型并且能與這個模型進行互動,所以,從這個意義上來說,BIM或將真的會改變工程造價模式。
