Inspections are performed at all critical stages of construction for compliance to The ANSI+ Standard. NOAH inspectors are Certified Professional Inspectors, utilizing InterNACHI CPI’s, Engineers, General Contractors, Plumbers, Electricians & Building Inspectors.
Inspections are performed by individuals, in-person or remotely, using an expert mobile application which can be hosted anywhere in the world. Recording of live stream video & audio allow the inspector to guide the builder through each inspection stage. Inspectors can also take snapshots/photos during video & make annotations to thoroughly document specific details.
NOAH maintains all inspection records for each NOAH Certified Structure using AES-256 encryption of data stored in world class secure facilities that meet PCI, HIPAA, Military and other regulatory requirements. Records are stored and retrievable by identifiers:
VIN - Vehicle Identification Number/or Other Identifier
NOAH Certification Seal Number
Builder Name
As stated above, each build gets inspected 5 separate times during the build.
Stage 1 Inspection - Trailer frame
VIN permanently attached
Dimension of frame and tongue metal
Cross-member spacing
Total trailer weight rating or axle weight rating
Number of axles, lug pattern, brakes, coupler size
Length and width of frame
House length & required trailer capacities:
Length
18' » 7,000 - 9,000 lbs
24' » 9,000 - 12,000 lbs
32' » 12,000 - 16,000 lbs
If your trailer doesn't have a total weight rating tag on it or a weight rating tag on the axles, here's a guideline to assist you:
Typical Axle Diameters Based on Axle Capacity
3,500-lb axle: 2 3/8-inch diameter
6,000-lb - 7,200-lb axle: 3-inch diameter
8,000-lb axle: 3-1/2-inch diameter
9,000-lb axles: 4-inch diameter
10,000-lb or more axles: 5-inch diameter
Stage 2 Inspection - Framing
Frame up with trailer mounts, all hold down straps and headers
Sheathing - Proper size & nail/screw pattern for rack bracing
Framing - proper headers supported by jacks and proper stud spacing.
