Change Orders Cycle Time and Volume
Change orders are agency-authorized, written documents that allow for modifications of a contract while the contract is being performed. Change orders are used to adjust the value of the contract or the time for performance, and are classified as either construction change orders or design change orders depending on the subject matter of a particular change order. Change orders allow the vendor to complete work included in the scope of the contract. They also allow the agency to make non-material changes to the scope, such as accounting for site conditions that were unknown at the time of contracting. This report includes aggregate, annual count and dollar amount of change orders by City agency.

Freshness
The publisher's promise
How the agency that publishes this data says it keeps the data current.
OverdueNo automatic refresh
- Automatic refresh
No scheduled refresh runs for this dataset. A refresh you ask for on this page runs anyway.
The publisher set a regular schedule for this dataset but has not updated it for far longer than that schedule, so the automatic queue skips it. An hourly triage lifts this fence once the publisher updates it again, which takes up to about 7 hours 15 minutes.

Columns
Each source column, with the name and type we use to store it.
The publisher has not provided a data dictionary.
0 of 8 columns carry a concept; 8 carry a description from the publisher. Read the concept column before you join. A column with no concept carries no claim from us, and a name that looks like a key is not one.
