## Description

HADDMS is a legacy drainage data management system in use by National Highways\. The Drainage Data Management System \(HADDMS\) contract was executed in 2021 to support the legacy system while a combined Drainage and Geotechnical Asset Management system was procured and implemented \(Geotech & Drainage Management System - GDMS\)\. GDMS is set to incorporate drainage asset data over the next 12-months, with a go-live date of October 2024\. The 1-year extension will support an important milestone in transitioning and validating the features and functions of the legacy system into the next integrated GDMS solution\. It will also allow for ongoing inventory submissions for drainage asset data\.
