Final answer:
The arch is allowed to include market fluctuations, material price changes, labor union disputes, and weather-related delays in estimates for the cost of work per B101. The correct answer is a) Market fluctuations.
Step-by-step explanation:
According to the B101 contract, the arch is allowed to include the following contingencies in estimates for the cost of work:
- Market fluctuations: This refers to the fluctuations in the prices of goods and services in the marketplace. The arch can account for market fluctuations by considering historical data and trends when estimating the cost of work.
- Material price changes: If the prices of materials used for the construction project are expected to change during the course of the project, the arch can include contingencies to account for these changes.
- Labor union disputes: In case of labor union disputes that may lead to delays or increased labor costs, the arch can include contingencies to account for these potential issues.
- Weather-related delays: If the construction project is susceptible to weather-related delays that may impact the cost of work, the arch can include contingencies to account for these delays.
