NASCLA Contractors Guide, Chapter 8 — Alternative Dispute Resolution
Material BreachvsImmaterial (Partial) Breach
A material breach is a serious contract violation that may void the contract and likely leads to litigation, while an immaterial breach is less serious, does not terminate the contract, and limits the injured party to suing only for the value of damages.

NASCLA Contractors Guide South Carolina, Page 7-2
Lump-Sum ContractvsFast-Track Construction

Project OverheadvsCompany Overhead
Project overhead costs are items necessary to complete a specific project (e.g., temporary storage, bonds, dumpsters) but not direct labor or materials, while company overhead costs are general business expenses (e.g., office rent, accounting fees) that cannot be linked to any specific project.

NASCLA Contractors Guide South Carolina, Page 7-5
Sole ProprietorshipvsC Corporation
A sole proprietorship exposes the owner to unlimited personal liability and terminates upon the owner's death, while a C Corporation provides limited liability but is subject to double taxation on profits and shareholder dividends.
