Section 3072 - Calculations and Test Procedures(a) The load-carrying capacity of elements or assemblies shall be established by calculations in accordance with generally established principles of engineering design. However, when the composition or configuration of elements, assemblies or details of structural members are such that calculations of their safe load-carrying capacity and basic structural integrity cannot be accurately determined in accordance with generally established principles of engineering design, structural properties of such members or assemblies may be established by the results of tests acceptable to the department or design approval agency.(b) When any structural design or method of construction is substantiated by calculations and supporting data, such calculations and supporting data shall be signed by a California licensed architect, or professional engineer and shall be submitted to the department or design approval agency as appropriate.(c) When the design of factory-built housing is substantiated by calculations or tests, all structural plans shall be signed by the architect or engineer in responsible charge of the total design.(d) When any design or method of construction is substantiated by tests, all such tests shall be performed by an approved testing agency acceptable to the department or design approval agency or shall be directed, witnessed and evaluated by an independent California licensed architect or professional engineer. All test procedures and results shall be reviewed, evaluated and signed by an independent California licensed architect or professional engineer. The approved testing agency, architect or professional engineer shall submit the evaluation of test results, calculations, and recommendations, accompanied by test reports from the laboratory, to the department or design approval agency. The department or design approval agency may require that its representative witness the test.(e) The manufacturer shall indicate how the units are transported from the factory to the site and provide specific calculations and any other information necessary to substantiate the capability of the unit to resist transportation and installation stresses.Cal.
