Climate Control System to be installed

Statement of Work (SOW) / Performance Work Statement (PWS)

To procure and install a fully operational greenhouse climate control system capable of simulating a Southeast Asian tropical environment for the Laboratory for Autonomous Systems Research (LASR) at the Naval Research Laboratory (NRL).

• Provide all labor, materials, equipment, software, installation, integration, commissioning, training, and documentation for the climate control system.

• Full responsibility for control system installation, integration with existing equipment, network infrastructure, configuration, and functional performance validation.

• Controlled systems include: heating, exhaust ventilation, circulation air movement, side/gable/roof vents, humidity control (fogging), solar shading, and outdoor weather monitoring.

• Hardware: UL/NEMA-rated control system including control panel, indoor sensors (temperature, humidity, light), and an integrated outdoor weather station (ambient temperature, humidity, wind speed, solar radiation, rain sensors).

• Software: Integrated monitoring, control, data management, user interaction, and diagnostics. Must provide real-time monitoring, continuous data logging with export, automated control with configurable setpoints, manual override capability, and fault detection/alarm notifications.

• IT Infrastructure: Contractor to install and configure control software on a government-provided server PC. System must support remote access if enabled by the Government.

• Communication: CAT6 cabling for direct communication between the government-provided PC and control panels. Contractor responsible for configuring controller communication settings.

• Maintain stable plant growth conditions year-round.

• Temperature Control: Target ~80°F (Heating: 75-85°F; Exhaust/Ventilation: 85-90°F).

• Humidity Control: Target ~80% RH (Fogging: 75-85%; Ventilation: 80-90%).

• Air Circulation: Continuous operation (low/high modes).

• Ventilation Control: Staged response based on temperature (e.g., ≥85°F roof vents open 20-30%, increasing with temperature).

• Shade Operation: Based on solar radiation/light levels, setpoints determined during commissioning.

• Weather Station Integration: Outdoor data used for vent restrictions, rain closure, and shading optimization.

• Remove existing and install all new control hardware, sensors, and weather station equipment.

• Furnish and install all control and network wiring (CAT6 or equivalent).

• Install, configure, and integrate all field devices and system components.

• Verify equipment compatibility and ensure full system interoperability.

• Perform point-to-point verification, sensor calibration, and communication verification.

• Functional performance testing of all systems.

• Acceptance criteria include maintaining temperature within ±5°F, humidity within ±5% RH, correct operation of all systems, full weather station integration, and functioning logs/alarms.

• Provide system design documentation, wiring diagrams, Sequence of Operations, installation/commissioning reports, operator/maintenance manuals, training materials, and as-built drawings.

• Provide on-site (or remote) training on climate control software for designated staff.

• Minimum one-year warranty covering all supplied equipment, hardware, installation, and system functionality.

Statement of Work (SOW) / Performance Work Statement (PWS)

To provide labor, tools, and materials for the installation of a new low voltage control system, including demolition of existing equipment and commissioning of the new system.

• Demolition / Removal: Remove and dispose of three (3) existing low voltage control panels and three (3) contactor panels. Disconnect and label existing wiring.
• New Panel Installation: Furnish and install one (1) new 60” x 36” Relay Contactor control panel. This includes panel mounting, anchoring, re-routing conduit, and termination of field wiring.
• Controls & Devices Installation: Install and connect the following devices:
  • One (1) access point controller
  • One (1) space temperature / RH sensor
  • One (1) backup temperature sensor
  • One (1) weather station
  • Provide all necessary low-voltage wiring, terminations, labeling, and testing for these devices.
• Commissioning: Commission the new control system, including point-to-point verification, sensor verification and calibration, and confirmation of device communication.

All materials, including Argus Controls system software and materials as detailed in the attached Argus proposal, are to be provided by the contractor.

Contractor will provide all necessary labor.
