Section 4019 - Calculations and Test Procedures(a) The load bearing capacity of elements or assemblies may be established either by specifications or calculations in accordance with generally established principles of engineering design, or by tests acceptable to the department. 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 shall be established by the results of tests acceptable to the department.(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. Such calculations or data supporting the design shall bear the architect's or professional engineer's seal, which may be a wet seal, or a secured electronic seal.(c) When any structural 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 shall be directed, witnessed and evaluated by an independent California licensed architect or professional engineer. All test procedures and results shall be reviewed and evaluated by a 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. The department may require that a representative of the department witness the test.(d) Notwithstanding the provisions of Subsections (b) and (c) of this section the department, in the capacity of a Title VI (24 C.F.R.) approved Design Primary Inspection Agency (DAPIA) may accept calculations and test results submitted by other than a California licensed architect or professional engineer providing such calculations or test results are found acceptable to the department upon review.Cal.
