The 2026 Unit Price Schedule (UPS) will go into effect on March 1, 2026. This formulaic change reflects a 2.8% increase linked to inflation as published in the Engineering News-Record 2026 Construction Cost Index (published in February 2026). Affected submittals include the following:
- New bond requests.
- Replacement bond requests.
- Bond extension requests.
- Bond reduction requests.
- New conservation deposit requests.
- Replacement conservation deposit requests.
- Future construction deposit requests.
In the case of development agreement extension and replacement requests, if the estimated value using the 2026 UPS exceeds the existing posted amount, the county will require supplemental security before approval of the request. As noted above, all bond reductions must be calculated using the 2026 UPS.
The 2026 UPS will be available at the Forms & Publications Library on March 1, 2026.
If you have any questions, please contact Morgan Wolfe in the Bonds and Agreements Center at 703-324-1519, TTY 711.
