What is one additional responsibility of the contractor beyond the IBC?

The correct choice highlights the contractor's responsibility to provide access for the special inspector, which is critical in ensuring that inspections occur as required under building codes, including the International Building Code (IBC). A special inspector is typically engaged to assess specific aspects of construction such as structural integrity or compliance with accepted standards and practices. Providing access allows the special inspector to perform their duties thoroughly and effectively, ensuring that all components of the construction meet legal and safety standards. This obligation emphasizes the contractor's role in facilitating communication and cooperation among all parties involved in the construction process, which is vital for maintaining quality and safety on the project site.

The other responsibilities, while important, do not directly relate to a specific requirement under the code as providing access for inspection does. Managing the project budget, hiring subcontractors, and conducting safety inspections are also critical aspects of a contractor's role; however, they may fall more into general project management responsibilities rather than specific obligations outlined in the IBC pertaining to inspections.
