Understanding the Demolition Plan
Demolition involves the careful dismantling and removal of building structures or specific parts of them in a systematic fashion. Before proceeding, a comprehensive demolition plan needs to be created. This crucial document serves as a roadmap for the demolition process. It outlines methodologies, safety measures, and regulatory compliance and is typically submitted to the local governing body for approval.
Setting Up Your Revit Project for Demolition
Preparation is key when focusing on a demolition plan in Revit. Start by creating a new project or opening an existing one. To utilize the phasing feature effectively, access the Phases panel from the Manage tab. Familiarize yourself with existing phases like “Existing,” “Demolition,” and “New Construction,” allowing you to organize your demolition workflow better.
Creating Phases for Demolition
1. Navigate to the Manage tab and select the Phasing panel.
2. Open the Phases dialog and click on the “+” icon to add a new phase dedicated to demolition.
3. Name this phase appropriately, such as “Demolition,” and ensure it reflects the specific actions that will take place during this stage.
4. Assign relevant parameters to the phase. Make sure it outlines essential details like timing and order of operations.
Displaying Elements According to Phases
Use Phase Filters to accurately represent the elements in your demolition view:
1. While in the Phasing dialog, click on the Phase Filters tab.
2. Create a new filter by clicking “New” and assign it a name that corresponds with demolition.
3. Select display options to show elements that are either existing or newly added based on their respective phases. For a demolition scenario, choose settings like “Show Previous + Demo” to reveal both intact structures and those slated for removal.
Selecting and Modifying Elements for Demolition
When ready to select elements for demolition:
1. Use the selection box tool by dragging around the elements you wish to modify or remove.
2. Once selected, navigate to the Modify tab and choose the Filter option where you can refine your selection based on specific categories relevant to the demolition.
3. To apply demolition to walls or rooms, simply set the phase to “Demolition” and adjust the phase filter accordingly to illustrate which elements need to be omitted from the new construction.
Documenting the Demolition Plan
A thorough demolition plan should include the following critical pieces of information:
1. **Location Details**: Clearly specify where the building is situated, including site plans and geographical context.
2. **Proximity Analysis**: Assess and document distances between the demolition site and nearby structures, roadways, and schools to ensure compliance with local regulations and safety standards.
3. **Structural Support Considerations**: Note any existing structural supports that must be considered to prevent unintended damage during the demolition process.
4. **Methodology**: Outline step-by-step demolition methods, sequencing, and techniques. Be specific about mechanical versus manual methods of demolition that will be utilized.
FAQs
**What types of demolition can be executed within Revit?**
Different forms of demolition include total demolition, selective demolition, mechanical methods, and implosion techniques. Each method has distinct requirements and risks, which should be evaluated accordingly.
**Can I visualize both demolition and new construction phases in the same view?**
Yes, by setting up your phase filters accurately, you can visualize existing structures, those scheduled for demolition, and elements planned for new construction cohesively within the same view.
**Is it necessary to get a permit for demolition projects?**
Yes, most jurisdictions require a permit for any demolition activities. A compliant demolition plan must be submitted to the local authority for approval before any physical work begins.
