(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.
