The construction drawings are a fundamental part of the contract documents that graphically communicate the design intent. To ensure a specific product is used and not overlooked by bidders, it should be clearly identified on the drawings. This is typically accomplished through a lighting plan showing the fixture locations and a corresponding fixture schedule on the drawings that lists the specific manufacturer, model number, and other required characteristics. This direct and visual method is the most effective way to convey a mandatory product requirement during the construction documents phase.

A. Identify the fixtures in the performance specification: A performance specification defines the required operational outcomes (e.g., light output, energy use), not a specific product, allowing the contractor to select any fixture that meets the criteria.

B. Issue an addenda that highlights the franchise branding requirements: An addendum is a modification issued after the bidding documents have been released but before bids are due. The correct initial method is to include the requirement in the original documents.

Chapter 10.2, "Drawings": This section explains that drawings graphically show the design, location, and dimensions of the work. It states, "Schedules are typically included on the drawings... to convey a large amount of information in a tabular format," which is how a specific light fixture would be identified (p. 657).

Chapter 11.2, "Specifications": This chapter defines specification types. It clarifies that a performance specification is "a specification that describes the desired end result of the work," which is inappropriate for this scenario. In contrast, a proprietary specification names a specific product, which is the owner's requirement (p. 708). Option A is therefore incorrect.

Chapter 12.2, "Bidding Procedures": This section defines addenda as modifications issued "during the bidding period," confirming that this is not the primary method for including information in the initial document set (p. 751).

Article 1, Section 1.1.1: This section defines the Contract Documents as including the Drawings and Specifications. This establishes that placing the requirement in the drawings is a standard and contractually binding method of communication.
