建築信息模型(BIM)的商業價值

近年,建築界冒起了BIM(Building Information Modelling 建築信息模型)這個技術名稱。BIM是一種電腦應用方法,將建築設計資訊以3D模型,加上設計資訊在軟件內完整的紀錄,就象一幢虛擬的建築物在電腦上建立。 但實際上,建築、結構工程及屋宇設備等專業本已各有一套成熟的技術,為何業主及建築公司需要投資BIM項目?為何技術人員需要學習一套全新的技術?究竟BIM有甚麼實質的好處? 美國McGraw Hill Construction的報告《BIM建築在全球主要市場的商業價值:世界各地的承建商如何使用BIM推動創新 》報導,在2013年於最有代表性的國家中,¾的承建商表示他們對BIM項目的投資有正面的回報率(ROI),以下是三點為承建商認為對BIM ROI影響最大的要素:

減少錯誤和遺漏

使用BIM設計及模擬,可在施工前找出建設過程中的潛在問題。由於建築模型的數據互相關連,BIM團隊能更確保資料的完整性和準確性。47%的BIM用家認為這是最直接影響高投資回報的原因,技術越成熟的用家越能認知這個好處。

減少修訂/加強與項目持份者協作

能在早期修復問題,即減少了規劃中的問題,也等於減少工地上的麻煩-57%的承建商看到減少修訂的好處,77%專業用家更認為是BIM最大的好處。另外,BIM有效提高項目關鍵成員之間的協作,例如BIM軟件Autodesk Revit 2014為建築設計,結構工程和機械、電氣和管道工程提供了理想的協作環境,改善了項目交付的過程。

降低建設成本

運用BIM收集並同步建設系統及組件設計數據,自動化及取代了艱巨的人手點算及測量,作出更早及更頻密更精準的材料用量預算,以便用家產生預備成本影響評估及替代成本權衡的設計方案。 在未來2年,承建商預計涉及BIM的工作將有50%的平均增長,他們都對如何進一步提高投資回報都有很清晰的計劃。 天行凝方是Autodesk認可培訓中心,擁有全港最新最廣的BIM培訓體系,包括Revit, Navisworks, Civil 3D及Design Review課程,學員修畢課程均獲Autodesk簽發修業證書。天行凝方由2008年起已成功培訓數以千計的工程人員具備操作與管理BIM相關應用技能,未來也會以提升本港BIM技術人員水平為目標,令他們在職場上發光發熱。

In recent years, a new jargon emerges in the Constructional Industry: BIM (Building Information Modeling).  BIM is a computer technology dedicated to the AEC industry, which visualize architectural design with 3D model and record building information with properties parameters. BIM is like a virtual building established using a computer.

But in fact, architecture, structural engineering and building services professionals are highly skilled in using their own old tools, why would owners and construction companies need to invest in BIM projects? Why technicians need to learn a new technology? What benefit can BIM really bring?

McGraw Hill Construction, US, reported that in 2013, ¾ contractors found a positive Rate Of Return (ROI) from their BIM project investment from its full report “The Business Value of BIM for Construction in major Global Market: How Contractors around the World are Driving Innovation with Building Information Modeling”.  The following are points are believed to be the greatest impact of BIM ROI:

Reduced Error and Omissions

Virtual design and construction with BIM create the potential to identify problems earlier in the building process. With interoperable exchange of models and data, team players can better ensure that information is complete and accurate. Half of all users (47%) see this as a significant benefit, particularly contractors. More experienced users recognize its value compared to others.

Reduced Rework/Strengthen Collaboration with Stakeholders

Fixing problems early, means fewer issues in the plans and ultimately fewer hassles in the field. A majority of contractors (57%) see the potential of BIM to reduce rework as a significant benefit. This is the highest-ranked benefit reported by expert users (77%).  Else, Contractors cite BIM’s ability to enhance collaboration among key team members as its most important contribution to improve the project delivery process.  For instance, Autodesk Revit the BIM software provides seamless collaboration functions for Architecture, Structural Engineering and Mechanical, Electrical, & Plumbing (MEP) Engineering.

Reduced Construction Cost

Collect and synchronize building system and component design data with BIM to more accurately calculate material quantities. Automate the laborious process of manual counting and measurement in order to perform estimates earlier and more often. Generate an unlimited number of component assemblies to better evaluate the cost implications and alternative cost trade-offs of design options.

Over the next two years, contractors expect the percentage of their work that involves BIM will increase by 50% on average.  They all have a clear picture on how they can improve BIM ROI.

Form.Welkin is an Autodesk Authorized Training Center which has the broadest BIM Training curriculum, including courses of Revit, Navisworks, Civil 3D and Design Review.  Upon course completion, students can get Autodesk Certificate of Completion.  Form.Welkin has nurtured thousands of engineers on BIM project operation and management since 2008.  In the future, Form.Welkin will aim on improving the BIM technicians’ level, and enable them to shine in their workplace.
