Mega Contracts Monitor ($100M+) — September 04, 2026

CADDELL CONSTRUCTION CO. (DE), LLC faces high execution risk on its $484.2M firm-fixed-price embassy construction contract in Ulaanbaatar, Mongolia. Cost overruns on a complex design-build project in a foreign location could compress margins.

The $357.9M DAI GLOBAL LLC USAID contract (Prosper Africa) runs through September 2026 and is vulnerable to potential budget cuts or policy shifts under a new administration, given USAID's discretionary funding nature.
