In a design and build project, model change monitoring is a big topic which will affect the whole construction and design life. A good monitoring of the model change  can effectively find out the potential issues of the change and trase the issues directly and immediately. In this blogger, I will like to share the method to monitor the model change of structure model whcih already successfully used in my project. Then, I will share some possible method to monitoring the model change of architecture model and MEP model and the difficulties in my project. Ready previous structure model and current model In my project, we will compare the model bi-weekly. So first I will prepare the structure model in last bi-weekly and model in current bi-weekly. Create Automation to extract the geometry data In my project, I use dynamo to extract XYZ location and size of beam, column, slab and bearing wall of both previous and current model.

  In AEC world, there is several laws and rules to control the building design, structure design and MEP design. Headroom is one of the common rule that control the emergency routes or the car parking routes of the building. In this blogger, I would like to share and useful tools which can check the headroom of building refer to the model. Introduction of Solibri Solibri is an open bim software which accept the IFC format. Base on some man-made ruleset, it help to check the quality of the imported model. The common usage is use to check headroom, width of access, distance between pipes, clash of elements, etc. Workflow of checking headroom 1. Export IFC file from BIM software From the effort of openBIM company, most of the BIM software can export IFC file. Besides use Solibri,.  please ensure the coordination system and export. For example, Revit can export IFC 2.3 to IFC 4.0 base on share coordinates. Also, if different headroom checking is need for different room. Please gro...

Continues to the blogger of CBWD, I would like to share more detail about the slab and wall opening modelling and the usage of this model and detail workflow. This model can large help for construction cost, mep coordination and building progress. Workflow of creating slab and wall opening model 1. Create door opening, Louvre opening and Acess opening Create architectural opening base on preliminary architectural model automatically . 2. Create MEP Opening Create MEP opening base preliminary MEP model automatically. Magical is one of the rebut addin to create MEP opening base routing and wall 3. Update opening base on CBWD needs Update the opening manually base on the comments on CBWD. This stage may need large manually works. 4. Lock the frozen opening After the CBWD is approved and available for construction, lock the related opening. This stage is to confirm the opening model match site construction . Usage of Slab and wall opening model 1. Benefits for future MEP rearrangements Whi...

Clash detection stands as a formidable pillar of Building Information Modeling (BIM), offering the power to unearth clashes among BIM objects. During construction, conflicts like beams intersecting with pipes or drainage systems clashing with AC ducts can vex engineers, potentially causing setbacks in the project timeline. BIM steps in as the solution, allowing proactive coordination and early resolution of these issues. The keystone in this process is the Clash Report, a dynamic presentation dashboard that grants visibility into and control over clashes among BIM objects. Its core mission: elevating model quality and driving project members to collaborate on issue resolution. 衝突偵測是建築信息模型（BIM）中的一個強大支柱，具備發現BIM對象之間衝突的能力。在建設過程中，諸如樑與管道相交或排水系統與冷氣管道發生衝突等問題可能會令工程師困擾，可能導致項目進度受阻。 BIM作為解決方案，允許積極協調和早期解決這些問題。這個過程的關鍵是衝突報告，一個動態的演示儀表板，可以查看和控制BIM對象之間的衝突。其核心使命是提升模型質量，推動項目成員合作解決問題。 Creating Selection Sets of BIM Objects in Navisworks: 在Navisworks中創建BIM對象的選擇集： To wield clash detection effectively, it...

Producing Combine Builders Work Drawings (CBWD) for opening construction is an intricate process that involves a harmonious collaboration of Architecture, Structure, and Building Services. CBWD encompasses various types of openings, such as wall openings (doors, windows, AC ducts, fire suppression pipes, etc.), slab openings (tower cranes, material hoists, AC risers, etc.), and beam openings (primarily for drain pipes). Throughout the CBWD workflow, each stakeholder plays a crucial role in ensuring that construction adheres to standards and client requirements. For example, architects specify door and window sizes, engineers assess the impact of openings on the main structure and provide calculations, and building services engineers reroute Mechanical, electrical, and plumbing ( MEP) systems to accommodate opening locations. 製作合併建造工程圖(CBWD)以進行開口建設是一個複雜的過程，需要建築、結構和建築服務的協同合作。CBWD包括各種類型的開口，如牆壁開口（門、窗戶、空調管道、消防供水管道等）、板條開口（塔吊、物料提升機、空調升降機等）和梁開口（主要用於排水管道）。在整個CBWD工作流程中，每個利益相關者都在確保建設符合標準和客戶要求方面發揮...

In the complex world of Building Information Modeling (BIM), where engineers, designers, and clients collaborate on intricate construction and design projects, a critical challenge arises: the identification and resolution of issues. These issues encompass a wide range of concerns, including modeling discrepancies, design flaws, and crucial comments. To navigate this landscape and expedite the seamless resolution of these issues among diverse stakeholders, a robust issue tracking process is essential. 在建築信息模擬（BIM）的複雜世界中，工程師、設計師和客戶共同合作進行精密的建設和設計項目，出現了一個關鍵挑戰：問題的識別和解決。這些問題涵蓋了一系列問題，包括建模不一致性、設計缺陷和重要評論。為了在不同利益相關者之間迅速解決這些問題，需要一個強大的問題跟蹤流程來引導這個過程。 Enter BIM Track, a powerful platform designed to streamline the issue management process within the realm of BIM. BIM Track serves as the cornerstone for efficiently tracking, storing, and facilitating the approval of issues that crop up during the modeling phase. Let's delve into the workflow and explore the benefits and limitations of this indis...

5D cost analysis is a common use of BIM in construction. It involves inputting item costs into the model to estimate building material expenses. Additionally, it tracks construction progress, aiding Quantity Surveyors (QS) in monitoring costs. In this blog, I'll share a method for monitoring construction foundation costs. BIM 的常見應用之一是進行 5D 成本分析，通過在模型中輸入不同項目的成本來估算建築物的材料費用。此外，它還跟蹤施工進度，幫助工程量測師（ QS ）監控成本。在這篇博客中，我將分享一種監控地基建設成本的方法。 Creating the Foundation Model: 創建基礎模型： Before QS payroll, prepare a dynamic foundation model. Since designs and construction limits change, ensure it's adaptable. 在進行 QS 工資支付之前，應準備好一個靈活的地基模型。由於設計和施工限制經常變化，因此確保它具有適應性。 Creating a Schedule with Unique Marks: 創建帶有獨特標記的進度表： Generate a schedule for foundation items with status markers like "Constructed" (completed), "Test" (testing), "Failure" (demolished or rejected), and "Not Constructed" (not done). 生成基礎項目的進度表，其中包含 " 已建成 " （完成）、 " 測試 " （完成測試）...
