The LGSF 'decision/supply chain' as it currently exists involves the following eleven players:

1-Building owners, who must see and appreciate the economic advantages in the framing system being chosen. They must be convinced that LGSF fits all their programmatic requirements.

2-Architects, who are intimately involved with the early choice of a building's framing system. However, most architects don't have an adequate understanding of how LGSF framing affects costs, codes, fire-protection, and life cycle operating costs. They must typically look to others who have more knowledge and experience, and it's at this point where they will hear many different and often confusing opinions.

3-Structural engineers (SE) are usually selected by, and work under the direction of, the project architect. SE's prepare conceptual design drawings, which incorporate general design standards and methods of detailing. At this point in time, most SE's generally also don't have a thorough understanding of costs, codes, detailing, etc. On some projects an SE 'of record' might work with an engineer who has more experience with LGSF.

4-The General Contractor (GC) usually helps the owner define the total project scope of work, including the LGSF Scope of Work. He initially prepares an estimated project budget. If LGSF is used, the GC must is responsible for coordination between the A&E team, the LGSF component supplier(s), and the LGSF installer.

5-Component manufacturers, who prepare shop drawings for fabrication of wall panels. In some cases a component manufacturer may hire a structural engineer directly to form a 'design-build' delivery team which can deliver both structural engineering design and the physical LGSF products.

6-LGSF Consultants, who are very rare, can specialize in assisting the whole A&E design team with information used to make key decisions during the critical design phases of the project.

7-Roll-forming companies (RFC) usually sell their rolled products to either (a) component manufacturers (above), or (b) steel-framing subcontractors-usually large drywall companies.

8-Local Retail Outlet. Some RFC, like Dietrich, sell products only through a local supply yard, rather than selling straight to the end-user.

9-LGSF Truss Manufacturers, and their supporting truss engineering staff, who over-stamp truss shop drawings prepared by the local manufacturer. Some component manufacturers build both wall panels and trusses.

10-LGSF Installer, is usually either a framing company, or a local drywall company with previous experience.

11-Minor sub-component manufacturers. Local RFC's usually cannot supply every LGSF component, for example: holdown systems, shear wall panels, connectors, and other components.
