The Engineering Field Tools (EFT) is a framework of engineering tools for field office individuals to plan and design commonly applied conservation practices. Currently there are four applications within the EFT, Survey Engineering Tool (SET), Grassed Waterway Design Tool (WDT), Terrace Design Tool (TDT), and Hydraulic Formulas Tool (HFT).
NRCS employees can access the EFT from the Windows Start Menu by selecting: Start/ All Programs/ Engineering Applications/ Engineering Field Tools/ EFT 18.104.22.168
Non-NRCS employees can download a public version by going to the EFT web page using the link provided above (scroll to the bottom of the page for downloading instructions).

AWM 2.4.0 Software and Database (October 2011) Ver. 2.4.0 of AWM software available to download (CCE) Installation and User Guides are available to download in PDF format Database Version 2.8.1 (Revised on Oct 2011) available to download
The AWM 2.4 requires MS Access for it to run successfully. It stores information on animals, beddings, climate, separators and several other parameters required for AWM. The AWM 2.4 database file (awm_data.mdb) is not compatible with prior versions of AWM. However, AWM 2.4 can read older versions of AWM project (*.awm) files but once they are saved in AWM 2.4, the saved project files cannot be used with older versions of AWM. Similar to the AWM program executable (awm.exe), the AWM database file (awm_data.mdb) is occasionally updated with latest information. Check the AWM Software Updates section for any future updates of the AWM database that may be available
