✍️ Sample CFB Questions & Answers
1. What is the purpose of a 'capillary break layer' in a USGA-method golf green or premium sports field construction?
A properly sized gravel layer creates a capillary break that prevents water from wicking upward into the sand root zone, keeping the interface between layers hydraulically distinct.
2. Which of the following is classified as an 'indirect cost' on a construction project?
A project superintendent's salary is an indirect (general conditions) cost because it supports the overall project rather than being tied to a specific work item.
3. Which code section typically addresses egress window requirements for sleeping rooms in residential construction?
IRC Section R310 specifies emergency escape and rescue opening requirements, including minimum dimensions for egress windows in sleeping rooms.
4. Why is regular aeration important for natural turf fields?
Regular aeration is essential for natural turf fields as it involves creating small holes in the soil to alleviate compaction. This process allows air, water, and nutrients to penetrate deeper into the root zone, promoting stronger root development and improving the turf's ability to absorb water and resist stress.
5. Which term describes the process of transferring risk to subcontractors by requiring them to provide their own cost estimates for defined scopes?
Competitive subcontractor bidding transfers the cost risk for specific scopes to subs who submit firm prices, reducing the general contractor's estimating exposure.
6. What is the triple constraint in CFB project management?
Scope, time, and cost are interdependent: changing one affects the others. Managers must balance all three.
