Choose your reading task
Start with the task you need to complete, not with whichever page happens to be open. If you are preparing to discuss building work, use the planning route; if you are testing a technical claim, use the WTC 7 model route; if an old link brought you here, use the historical index. Each route is meant to answer a specific reading question and leave you with a usable note, not a universal rule. These are reading aids, not regulatory requirements.
Prepare for a building-project discussion
Ask what information and questions you should bring to a conversation with a builder or designer. The guide is intended to produce a reusable checklist covering your desired outcome, existing information, scope, responsibilities, open questions, changes and handover. It is owner preparation, not a construction schedule, design service, cost estimate or universal permit and legal checklist, so confirm local requirements separately.
Follow a technical claim to its source
Ask how to read the purpose, evidence, assumptions, comparison with video, and limitations of NIST's WTC 7 model. The page explains what the model was designed to explain, which evidence and modeling assumptions it used, how the simulation compared with video, and where the model has limits. Keep the model itself central: an animation is not a complete recording, and its case-specific findings do not transfer to a new project. Use those sections to locate what the source says and what it leaves unresolved.
Follow an older link in its historical context
If an old link brought you here, ask which earlier announcement or media subject it referred to. This historical index is intended to organize entries by subject, with a verified date when known, the original's availability and the status of any current summary. Do not read old announcements as current news or infer order from the wording of a web address. Keep campaign summaries separate from technical findings; a historical reference is not evidence of an active campaign.
Keep the question, source and context together
When you follow any route, keep the question, source details and context in one note. Record the source title, author or organization, date or version, relevant section, your exact question and any unresolved point. If you share the page, use its descriptive heading as the link label, pair it with the page address and add a sentence explaining the question it answers. Distinguish a summary from an original and do not present historical material as current news. These are reading suggestions, not regulatory requirements.
