1. When is a Design Professional required for my project?: The Indiana Administrative Code; 675 IAC 12-6-9, Design professionals states "Design professionals are required for the construction of Class 1 structures where a design release is required, except any of the following:
- Class 1 structures with 30,000 or fewer cubic feet of space.
- Additions to Class 1 structures if the addition adds 30,000 or fewer cubic feet of space.
- Alteration to a Class 1 structure if the alteration does not involve changes affecting the structural safety of the Class 1 structure.
- Installation or alteration of an automatic fire sprinkler system in a Class 1 structure designed by persons as described in subsection (b). Indiana Administrative Code - 675 IAC 12-6-9 (PDF)

2. When is a State Construction Design Release (CDR) required?: The Indiana Administrative Code; 675 IAC 12-6-3, Design release; requirement states, "No construction shall be done on a Class 1 structure until a design release has been issued by the division unless the construction is of a type specifically exempted from the design release requirements by section 4 of this rule. Design releases may be issued by the division.

If a foundation release is obtained under section 14 of this rule, construction may:
- Be done to the grade level only as provided for by section 14(c) of this rule
- Not go beyond that point without the issuance of a design release or a partial design release authorizing the further construction.

If a partial design release is obtained under section 15 of this rule, construction may be done to the extent of the partial design release but it may not exceed that scope without the issuance of a design release or another partial design release authorizing the further construction.

7. What is Fire-Resistance-Rated Construction?: Building construction in which the structural members (including walls, partitions, columns, floors, and roof) are used for the separation of adjacent spaces to safeguard against the spread of fire and smoke within a building. See Fire Resistance Rated Construction resource for more information. Fire Resistance Rated Construction Page

8. Is a fire wall the same as a fire barrier?: No. A Fire Wall is fire-resistance-rated wall which restricts the spread of fire and extends continuously from the foundation to or through the roof, with sufficient structural stability under fire conditions to allow collapse of construction on either side without collapse of the wall. A Fire Barrier is a fire-resistance-rated wall assembly of materials designed to restrict the spread of fire in which continuity is maintained.
