Final answer:
Supplementary provisions or special conditions in a construction contract have specific purposes, such as addressing unique requirements and variations. An example of a special condition is the inclusion of a liquidated damages clause for missing project deadlines.
Step-by-step explanation:
The purposes of supplementary provisions or special conditions in a construction contract are to address specific requirements, conditions, or variations that are unique to a particular project. They are included to provide clarity, control, and flexibility in the contract. An example of a special condition is the inclusion of a liquidated damages clause that specifies the amount of money the contractor would have to pay if they fail to meet the project deadline.
Special conditions are included in separate sections of the contract because they are project-specific and may not apply to all contracts. General conditions, on the other hand, contain standard provisions and clauses that are applicable to all contracts.
