Design solutions for engineered components are considered delegated design. In these cases, a contribution by a registered professional is required to complete the deferred design component, or the component is directly associated with building code compliance. This category includes items such as:
- structural steel connections;
- steel decking;
- composite steel (owsj, heavy truss);
- wind loadbearing studs;
- light gauge loadbearing cold-formed framing;
- stairs;
- guard and handrail anchors to structure;
- custom guards and handrails (non-pre-engineered systems);
- composite wood (trusses, mass timber, glued-laminated [glulam] timber, etc.);
- curtain wall anchors to structure;
- custom curtain wall—themed or non-pre-engineered systems (this would be better forming a part of pre-construction design-assist category);
- fall arrest anchors to structure;
- fire suppression systems; and
- seismic restraints for non-structural systems.
This list is not intended to be all-inclusive, and additional content will need to be considered for future development of delegated-design components.
Design solutions for specialty components are considered assigned design. A contribution by a registered professional is not required for code compliance, but certification or confirmation of properties is required. This category includes items such as:
- concrete mix design;
- door hardware (this would be better forming a part of pre-construction design-assist category);
- firestopping;
- skylights;
- pre-engineered guards and handrails;
- fall arrest systems (this would be better forming a part of pre-construction design-assist category, but is often dealt with as post-construction design-assist contribution);
- standard pre-engineered systems;
- custom canopies;
- pre-engineered structures; and
- integrated security systems (this would be better forming a part of pre-construction design-assist category).
