1. PROJECT TITLE: Building 374 TSI controller/monitor Digital Interface Module (DIM) Replacement

2. PROJECT LOCATION: Foreign Disease-Weed Science Research Unit

1301 Ditto Avenue Fort Detrick, Md 21702

3. INTRODUCTION

The USDA, Agricultural Research Service, Foreign Disease-Weed Science Research Unit has two distinct missions united by a common relationship to plant pathology and the unit’s unique Biosafety Level 3 (BSL-3) plant pathogen containment laboratory and greenhouse facilities.

The mission of the foreign disease program is to develop techniques for the rapid detection and identification of new and emerging crop pathogens, and to provide fundamental information on the biology and epidemiology of emerging pathogens for risk assessment and disease management strategies including the development of resistant plants.

The mission of the weed biological control program is to collect foreign pathogens overseas from weeds in their native habitat, and to evaluate, characterize and release the pathogens in the U.S.

for biological control of introduced weeds, leading to improved, sustainable weed control practices in agricultural systems with reduced dependence on chemical herbicides.

4. BACKGROUND

Building 374, the Plant Pathogen Containment Headhouse/Greenhouse at Fort Detrick, Maryland, is a BSL-3 high containment facility with change-in/change-out protocols. The building consists of laboratory and office space areas. Scientists study high impact domestic and foreign pathogens in the laboratories of Building 374. The building was originally constructed in the mid-1950s and it was last renovated in 2015. The TSI Adaptive Offset Controllers and Room Pressure monitors that were installed during the renovations are scheduled to become obsolete and the units will not be available. The TSI controllers and monitors are an integral part of the buildings automation system and must be functional at all times.

5. PROJECT SUMMARY

The United States Department of Agriculture (USDA), Agricultural Research Service (ARS), Foreign Disease-Weed Science Research Unit intends to replace all aging TSI Adaptive Offset Controllers and Room Pressure monitors throughout the facility.

6. TECHNICAL REQUIREMENTS

Units must integrate to the building automation system using digital communication system BACnet™
