Optimizing Construction Efficiency with Clash Detection in BIM (Naviswork) 透過BIM的衝突偵測優化建築效率

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's vital to categorize diverse BIM objects into selection sets. This segmentation streamlines the management of different aspects of the project. Here's a sample grouping:

要有效地使用衝突偵測，將不同的BIM對象分類為選擇集至關重要。這種分段可以簡化項目不同方面的管理。以下是一個示例分組：

Architecture Items 建築物品:

1. Doors 門

2. Windows 窗戶

3. Block Wall 磚牆

4. Fire Shutter 防火百葉窗

5. Ceiling 天花板

Structure Items 結構物品:

1. Column 柱子

2. Beam 樑

3. Bearing Wall 支撐牆

4. Stair 樓梯

MEP Items（機電）物品:

1. Drainage Related 排水相關

2. Plumbing Related 水暖相關

3. Air Conditioning System Related 空調系統相關

4. Fire Service Related 消防服務相關

5. Electricity Related 電力相關

6. Information and Communication Technology Related 信息與通信技術相關

Creating Clash Detection Rules for Selection Sets 為選擇集創建衝突偵測規則:

With BIM objects grouped, it's time to craft clash detection rules based on these selections. Here are some examples:

將BIM對象分組後，現在是時候基於這些選擇集制定衝突偵測規則了。以下是一些示例：

1. Doors vs. Bearing Wall 門與支撐牆

2. Column vs. Drainage Related 柱子與排水相關

3. Fire Shutter vs. Electricity Related 防火百葉窗與電力相關

Exporting Clash Results and Creating Dashboards:

將衝突結果匯出並創建儀表板：

Now, let's harness the power of clash detection. Begin by exporting clash results to Excel or Google Sheets, providing structured data for analysis. Subsequently, construct informative dashboards using this data. These dashboards act as visual aids, facilitating a deeper understanding of the clashes.

現在，讓我們利用衝突偵測的威力。首先，將衝突結果匯出到Excel或Google Sheets，提供結構化數據以進行分析。隨後，使用此數據建立信息豐富的儀表板。這些儀表板作為視覺輔助工具，有助於更深入地了解衝突情況。

Prioritizing Clash Results:

優先處理衝突結果：

Recognizing that not all clashes are equally critical, prioritize them based on their impact:

High Priority: Column vs. Drainage Related

Medium Priority: Fire Shutter vs. Electricity Related

Low Priority: Fire Service Related vs. AC Duct

需要注意的是，並非所有衝突都同樣重要，一些可以忽略不計。但是，工程師通常會花費大量時間手動解決不太重要的衝突，以減少干擾。此外，有必要將衝突報告存儲在一個集成平台上，項目成員可以在桌面或便攜設備上訪問和查閱，確保協作和可訪問性無間斷。

Sharing Results and Encouraging Collaboration:

分享結果並鼓勵合作：

Finally, share the clash results with all project stakeholders. Distribute comprehensive clash reports and present the findings during coordination meetings. The goal is to highlight clashes, motivating stakeholders to collaborate and swiftly address high-priority issues, ensuring the project stays on course.

最後，與所有項目利益相關方分享衝突結果。分發全面的衝突報告，並在協調會議中展示發現。目標是凸顯衝突，激勵利益相關方合作，迅速解決高優先級問題，確保項目保持在正軌上。

Takeaways and Impressions:

心得和感想：

It's worth noting that while clash detection is a powerful tool, not all clashes are equally critical, and some can be safely ignored. However, engineers often spend considerable time manually resolving less important clashes to reduce clutter. Furthermore, it's essential to store the clash reports in an integrated platform accessible to project members on desktop or portable devices, ensuring seamless collaboration and accessibility.

值得注意的是，雖然衝突偵測是一個強大的工具，但不是所有的衝突都同樣重要，有些可以安全地忽略。然而，工程師通常會花費大量時間手動解決不太重要的衝突以減少干擾。此外，有必要將衝突報告存儲在一個集成平台上，項目成員可以在桌面或便攜設備上訪問和查閱，確保協作和可訪問性無間斷。
