Which of the following should an estimator take into account when reviewing specifications?

An estimator should take into account control joints and wall ties when reviewing specifications because these elements are critical for ensuring the structural integrity and proper function of the building. Control joints help manage cracking in concrete by allowing for movement due to temperature changes or settling, while wall ties are essential in providing stability and support between masonry walls and other structural elements.

Understanding these specifications allows an estimator to accurately assess material costs, labor requirements, and construction methodologies. This ensures that the project adheres to structural codes and standards, preventing issues during construction and in the building's long-term performance. Inaccurately estimating these important components may lead to oversights that can significantly impact safety and durability, resulting in potential additional costs down the line.

While paint and finish requirements, landscaping elements, and lighting fixtures are also important considerations, they typically relate more to aesthetics or functional features, rather than essential structural requirements, which makes control joints and wall ties more critical in the context of specifications.
