Alternates are best described as which of the following?

• A. Optional substitutions to base bid for different work or materials.
• B. A set completion date for the project.
• C. A list of project team members.
• D. Inclusion of performance bonds.

Answer: (A)

Alternates are optional substitutions to the base bid for different work or materials. They are presented in the bid package as add/ deduct items priced separately, allowing the owner to compare total project costs with different scope options and choose which ones to include to meet budget or design goals. If an alternate is accepted, the contract sum and scope are adjusted accordingly; if not, the base scope remains as bid. These are not about project schedules, team lists, or performance bonds, and they differ from post-award change orders because alternates are part of the bidding process used to shape the project before construction begins.
