Which method involves compiling a detailed estimate of all labor and materials?

The quantity survey method involves compiling a detailed estimate of all labor and materials required for a construction project. This method provides a comprehensive breakdown of costs associated with each aspect of the project, including the exact quantities of materials needed and the labor costs calculated in detail.

Utilizing this approach allows for a high level of accuracy in cost estimation, making it particularly useful for large or complex projects where precise budgeting is critical. It takes into account not just the overall cost but also the specifics of how much of each material will be required and the associated costs of labor, which can vary significantly depending on the scope of work.

In contrast, the square foot and cubic foot methods offer more generalized estimates based on overall dimensions, which may not capture the intricacies of specific labor or material costs in detail. The unit-in-place cost method, while more detailed than the square foot or cubic foot methods, does not provide the level of breakdown and specificity found in a quantity survey, focusing more on individual components rather than a comprehensive view of all labor and material estimates.
