Statement of Work/Overview:
Consultant to conduct an electrical & mechanical OR enclosure thermal scan (See requirements document to confirm which building gets which) using radiometric thermal imaging equipment (320w by 240h pixel image size minimum). These inspections are intended to identify all systems and to ascertain their physical and functional condition.
All thermal images to have associated reference visual photo.
• Note, for image clarity, all visual reference photos must be taken with a separate digital camera.
• Photos – NOTE (1): A copy of all original photos used for the report must be resized to the size of 640w x 480h (landscape image) prior to importing. The image “quality” setting during the re-sizing process should not be less than “80”.
• Photos - NOTE (2): If appropriate, all site inspection original digital photos should be taken in a landscape orientation. Each digital camera should have the image size setting set to a minimum of 3 megapixels.
THERMOGRAPHY DELIVERABLES
USB flash drive containing;
• Draft and Final searchable pdf copy of thermal inspection report(s);
• Updated Drawings indicating location of anomalies;
• All original sized photographs taken during the site inspection.
Mechanical and Electrical Scans
Thermally scan all;
• Electrical panels with covers off/open to expose all line and load terminations. Consultant IS required to provide qualified electrician to remove and replace all electrical covers.
• Operational and accessible pumps/motors and pulley/belt assemblies.
Visually inspect for any obvious Electrical Code violations while covers are off for thermal scanning.
• Digitally record all thermal image deficiencies in radiometric JPG format. Record thermal maps of equipment when camera operator is too close to capture line and load connections in one thermal image. Provide thermal deficiencies corresponding load readings for all applicable phases.
Prepare Electrical / Mechanical thermal deficiency report to include;
• Fault priority table,
• Table itemizing all uncovered thermal faults and associated repair priorities,
• Summary section highlighting any major anomalies,
• Summary section on all obvious code infractions,
• Thermal image fault page having top-bottom image layout and respective image information table, image information to include;
o Photo – Location, Component, Breaker/rating, Phase Loading
o Thermal Image – Filename, Date, Time, Distance, Emissivity, Ambient Temp., Reflected Temp.
Thermal image fault page to have REMARKS section with complete thermal image analysis.
Thermal Enclosure Scan:
Thermally scan all exterior walls from ground level and digitally record all thermal images indicating suspected anomalous regions. Where appropriate, thermal maps of larger deficient areas are to be recorded. All thermal images to have associated reference visual photo.
.
Ensure exterior walls to be pressurized using the building HVAC systems to obtain a minimum of 20Pa from interior to exterior. This pressure differential to be initiated a minimum of 20 minutes before thermal scanning and during the full thermal scan. During positive enclosure pressurization, complete an interior and exterior thermal scan. After positive pressure scanning, adjust the HVAC systems to provide a minimum negative 20Pa pressure across the exterior walls AND scan the walls from the interior and exterior complete with thermal images taken of notable deficient locations.
