Final answer:
The determination of how long the contract time will be extended in different situations is usually specified in the contract agreement. The agreement may outline procedures and provisions for time extensions in case of owner or architect negligence, delays caused by separate contractors, changes in the work, labor disputes, fire, or other causes beyond the contractor's control.
Step-by-step explanation:
In these situations, the determination of how long the contract time shall be extended is typically based on the terms and conditions mentioned in the contract agreement between the parties involved. The contract agreement may specify the procedures to be followed and who has the authority to make such decisions. For example, if the owner or architect is negligent, the contract may outline that the contractor is entitled to an extension of time to account for the delay caused by their negligence.
Similarly, if a separate contractor is delayed or if changes are ordered in the work, the contract may provide provisions for time extensions. Additionally, in the case of labor disputes or fire, the contract may allow for the contractor to receive additional time to complete the project.
In situations where there are causes beyond the contractor's control, such as natural disasters or unforeseen events, the contract may include a force majeure clause. This clause typically allows for a time extension to be granted if the contractor can prove that they were unable to fulfill their obligations due to circumstances beyond their control.
