Final answer:
To compute indirect costs, itemize job overhead, insurance, bond, and permits using RS Means data, and account for the project's 4-month duration. These costs are typically a percentage of direct costs, except for permits which have a fixed price.
Step-by-step explanation:
To compute the indirect costs for Billy C-Store project using the provided plans, first, you need to identify all the indirect costs mentioned in the question: job overhead, insurance, bond, and permit. Each of these costs will need to be calculated based on the provided assumptions and RS Means data for a national average Location, Open Shop, and Year 2018 commercial new construction.
Before you calculate each of these costs, prepare a table to outline and sum them up, including the project duration of 4 months (assuming 4 weeks per month, which leads to a total of 16 weeks).
For job overhead, you might consider costs such as project management, temporary facilities, utilities, equipment rental, and others. These are generally calculated as a percentage of the direct costs identified in the project. To determine the insurance and bonding costs, you will use rates provided by insurance companies and bonding agencies, which are usually also a percentage of the total project cost. Permits have fixed costs that are set by the local government and will be added outright.
