THE FULL TEXT OF THE PROPOSED RULE IS:
61G15-31.010 Design of Structures Utilizing Cold-Formed Steel Framing.
(1) Where the Engineer of Record has delegated the responsibility for truss design, the responsibilities of the Engineer of Record and the Delegated Engineer shall be as set forth in AISI standard S214, “Supplement 2 to the North American Standard for Cold-Formed Steel Framing-Truss Design”, Section B, wherein the Engineer of Record is the Building Designer and the Delegated Engineer is the Truss Design Engineer as those terms are defined in said standard. The Engineer of Record and the Truss Design Engineer shall have additional responsibilities identical to those stipulated for wood trusses in accordance with Rule 61G15-31.003, F.A.C. The Engineer of Record may also delegate the design of a truss system comprising cold-formed steel framing as outlined in Rule 61G15-31.003, F.A.C.
(2) A “cold-formed steel framing system” shall mean an assemblage of framing members (other than trusses) such as curtain walls, parapets, exterior soffits, ceilings, or other similar systems together with all bracing, connections between framing components, connections to supporting structure, and other related structural elements where noted on drawings prepared by the Engineer of Record, that, in combination, function to support the loads applicable to that portion of the structure. Where the Engineer of Record has delegated responsibility for the design of a cold-formed steel framing system, the Engineer of Record shall provide written design requirements to the delegated engineer and require structural delegated engineering documents for review. Structural delegated engineering documents shall include component and connection details, calculations, fabrication details and layout drawings. All such submittals shall identify the specific project. The effect of a cold-formed steel framing system on other parts of the building is the responsibility of the Engineer of Record.

61G15-31.011 Design of Aluminum Structures.
(1) These rules apply when an engineer is required to prepare signed, sealed and dated engineering documents for the design of an aluminum structure. These rules do not preclude the use of procedures established by Section 489.113, Florida Statutes.
(2) The engineer of record for the aluminum structure shall be responsible for all aspects of the structural design, including connection details, bracing, foundations and the ability of any existing structure to support the loads imposed by the aluminum structure.
(3) The engineer of record may elect to delegate the responsibility for the design of an aluminum structure to a delegated engineer. The engineer of record shall require the delegated engineer to submit for review structural delegated engineering documents prepared, signed, sealed and dated by the delegated engineer.
(4) The structural delegated engineering documents shall include:
(a) The governing codes with all supplements in effect at the time the documents were signed and sealed.
(b) The project name and its location.
(c) Plans, sections, elevations and details, necessary to define the aluminum structure.
(d) Material specifications for all structural components, including but not limited to screen densities, fasteners, and material thickness and type.
(e) The location, magnitude, and direction of controlling member forces and reactions and the controlling design load combinations at which they occur.

61G15-31.012 Design of Temporary Support Structures.
(1) This section defines the responsibility of the engineer (shoring engineer) who designs temporary support structures (shoring) used during construction, remodeling, alteration, and dismantling (herein referred to collectively as “construction”) of a structure. Shoring includes the design of formwork, shoring, reshoring, backshoring, lateral bracing and all other temporary supports for structures.
(2) The shoring engineer shall design the shoring so that the structure being supported is structurally stable during all phases of the construction of the structure and shall take into account, in the design of the shoring, the sequence of construction of the structure. The shoring shall be designed so that the loads imposed by the shoring system do not place more load on the supporting soil or the structure under construction than their capacity at that stage of construction.
(3) The design of the temporary support structure shall be as set forth in the editions of ASCE 37 and ASCE 7 that have been adopted by the Florida Building Code. If there is no adopted edition, ASCE 37-02 shall be used.
(4) The shoring engineer responsible for the design of the shoring shall prepare signed, sealed and dated engineering documents showing the size, material and location of all components necessary for the shoring of the structure under construction. The documents shall indicate the loads to be supported by the temporary shoring and shall include the assumptions used in the design of the shoring.
