Add, Edit & Delete Drainage Structures
From monitoring cleanouts to identifying criticality, the Drainage Structure Module in Roadsoft is useful for monitoring, evaluating, and reporting on the asset location, features, assessment, and activities related to drainage structures of all types.
These instructions are for editing one drainage structure at a time. To edit multiple drainage structures at once, see Use the Multi-Edit Tool.
While Roadsoft can be used to record new data on drainage structures, the Laptop Data Collector (LDC) is ideal for collecting drainage structure information. To use the LDC for collecting drainage structures, see Add, Edit & Delete Drainage Structures in the LDC.
The Drainage Structure Module includes inspections, work orders, and document attachment features. See Add, Edit & Delete Drainage Structure Inspections, Add New Work Order, and Add, Open & Delete Document Attachments for detailed instructions on these features.
Some fields in the Drainage Structure Module use lookups, the customizable selections found in most drop-down lists within Roadsoft. For help using Drainage Structure lookups, see Add, Edit & Delete Drainage Structure Lookups.
Add a Drainage Structure
