Reset the zoom level by clicking the ![Screenshot 2026-03-31 at 4.21.08 PM](https://success.join.build/hs-fs/hubfs/Screenshot%202026-03-31%20at%204.21.08%20PM.png?width=18&height=19&name=Screenshot%202026-03-31%20at%204.21.08%20PM.png) icon in the top right corner.* ### **Item Distribution Chart** At the top of the Timeline page, there is a chart showing the count of Items with decisions or due dates for each time period. This is a great way to track which Items are past due (red), which ones are upcoming (yellow), and which ones have already had a decision made (grey). Hovering over a bar will give you a summary of the Items in that time period, and clicking the hyperlink will take you to the [Items List](https://success.join.build/en/knowledge/items-list?hsLang=en) filtered for that time period. ![](https://success.join.build/hs-fs/hubfs/undefined-Apr-03-2026-07-23-44-9312-PM.png?width=670&height=109&name=undefined-Apr-03-2026-07-23-44-9312-PM.png) ***Tip:** Use the Item Distribution Chart to ensure upcoming work is spread out evenly across the weeks–this helps keep your workflow balanced.* ### Timeline Gantt The timeline visualizes your project plan and tracks progress. Use different activity types to highlight key events and milestones. #### Types of Activities There are four main types of activities in the Join Project Timeline: 1. **Phases** - A span of time in the project during which other work occurs.  1. Phases can contain Tasks and Milestones. 2. Phases have a Start Date, End Date, and a Duration derived from their children. 3. On the Timeline, Phases appear as dark blue bars with end ticks when expanded. 4. Examples: Schematic Design, Estimating, Preconstruction, Construction 2. **Milestones** - A significant point in time during the project, typically tied to a document issuance or published Estimate/Budget. 1. Milestones have a Start Date only (no End Date or Duration). 2. On the Timeline, Milestones appear as flags. 3. Examples: 50% Schematic Design, Design Development, Construction Documents, Guaranteed Maximum Price (GMP) 3. **Tasks** - A multi-day activity. 1. Tasks have a Start Date, End Date, and Duration. 2. On the Timeline, Tasks appear as light blue bars. 3. Tasks with a zero-day duration are automatically converted to **Events**. 4. Examples: Out to Bid, Permit Review, Mechanical Buyout, or Elevator Fabrication 4. **Events** - A zero-day occurrence that is important to be aware of or track. 1. Events have a Start Date and End Date on the same day, and a zero-day duration. 2. On the Timeline, Events appear as red-orange diamonds. 3. Examples: Proposal Due, Notice to Proceed, Owner-Architect-Contractor (OAC) Meeting, Project Turnover ***Tip:** Plan your work by assigning Items to upcoming **Events** (zero-day activities) such as OAC meetings or decision deadlines.* ### Connecting Items to Activities Connect Items to Timeline Activities to provide schedule context and clarify when work is happening or being coordinated in the project. #### **Why connect Items to Activities?** Connecting Items to Activities helps teams: - Understand when an Item is relevant in the project timeline - Align work with key milestones or phases - Improve visibility and accountability across cross-functional teams - Reduce ambiguity about ownership and timing Common Scenarios: - Link an **Item** to a *critical* *procurement Task.* - Link an **Item** to an upcoming or related *OAC Meeting.* - Link an **Item** to a handoff event, such as *Notice to Proceed.* Connecting Items to Activities ensures everyone shares the same understanding of what needs to happen and when, helping teams move work forward with confidence. #### **Connecting an Item to an Activity** ##### **From the** **Timeline**: 1. Click the linked text in the Items column to open the side panel. 2. Use the **+Add related Item** button to connect Items. ##### ![timeline with sidebar](https://success.join.build/hs-fs/hubfs/timeline%20with%20sidebar.png?width=670&height=409&name=timeline%20with%20sidebar.png) **From** **Item Details**: 1. Select a related Activity to assign to an Item. ![Screenshot 2026-04-03 at 12.46.05 PM](https://success.join.build/hs-fs/hubfs/Screenshot%202026-04-03%20at%2012.46.05%20PM.png?width=670&height=529&name=Screenshot%202026-04-03%20at%2012.46.05%20PM.png) ##### **From Items List**: 1. Select one or more Items by checking the box next to each to activate the **Bulk Item Editor**. 2. Click the **Edit Items** button. 3. In the **Activities** field, select an Activity from the dropdown and then click **Apply Changes**. ![bulk edit](https://success.join.build/hs-fs/hubfs/bulk%20edit.gif?width=670&height=430&name=bulk%20edit.gif) ***Note:** Read more about [why you should showcase a Timeline in Join](https://success.join.build/en/knowledge/why-timeline?hsLang=en).* -
