NCARB Project Development And Documentation (PDD) Practice Exam

The pricing options for potential scope changes are organized in a section dedicated to Alternates. This part of the specs tells bidders how to price alternate concepts, materials, or methods that the owner might choose to include or exclude, allowing the project to be adjusted without reworking the entire contract. It explains what constitutes an alternate, how to price each option, and how those prices affect the contract sum if an alternate is accepted (additive or deductive changes). In practice, the base bid remains the starting point, and accepted alternates modify the total accordingly, providing a structured way to evaluate value or design choices during bidding or construction. Other sections cover product requirements, unit price work, or contracting forms, but they do not address the mechanism for pricing scope-change options.
