Construction Documentation Flashcards

An architect is specifying a custom curtain wall system. The design intent requires the system to meet specific, measurable criteria for air infiltration, water penetration, and thermal resistance (U-value), but the architect wants to allow various manufacturers to propose their proprietary systems that can meet these criteria. Which type of specification is most appropriate to achieve this goal?

Answer: Performance Specification

A performance specification outlines the desired results and the criteria by which the performance will be verified, without dictating the specific materials or methods to be used. [3, 5, 7] This approach provides the contractor and manufacturer flexibility to innovate and select the most effective solution to meet the required outcomes, which is ideal for the scenario described. [5, 7]

In a standard Design-Bid-Build project, a contractor discovers a conflict where a wall assembly is shown as 2x4 studs on the architectural drawings but is described as 2x6 studs in the technical specifications. Assuming no other information is provided and the contract does not contain a specific order of precedence clause, what is the architect's most likely interpretation based on standard industry practice?

Answer: The specifications govern because they provide a more detailed, written requirement.

While standard AIA contracts state that documents are complementary [17, 27], a common principle of interpretation and a specific clause in many non-AIA or modified contracts is that the specifications take precedence over drawings in a conflict. This is because specifications are written documents that typically provide a higher level of detail and specificity regarding materials, quality, and standards than drawings can convey graphically. The architect's first step is to interpret the documents, and leaning on the more detailed specification is the standard approach before a change order is considered.

An architect is finalizing the documents for a public project to be competitively bid. Which of the following is a component of the Project Manual but is NOT part of the Construction Drawings?

Answer: Bidding requirements and Instructions to Bidders

The Project Manual is the bound volume of written documents that accompanies the drawings. It typically includes the bidding requirements (such as the advertisement to bid and Instructions to Bidders), contract forms, conditions of the contract, and the technical specifications. [1, 13, 15] Drawings, schedules, and graphic details are separate parts of the overall contract documents.

Three days before bids are due, a building product manufacturer informs the architect that a specified roofing membrane has been discontinued. The architect quickly selects a suitable replacement. What is the correct document the architect must issue to inform all bidders of this change?

Answer: An Addendum

An Addendum is a written modification to the procurement documents (drawings, specifications, etc.) issued by the architect *before* the date for receipt of bids. [4, 9, 12] Its purpose is to clarify, correct, or change the documents during the bidding period. Change Orders, ASIs, and CCDs are all used *after* the construction contract has been executed.

A contractor is reviewing the architectural drawing set to prepare a bid. To find consolidated information on the specific type, size, material, finish, and hardware for every door in the project, the contractor should look for the:

Answer: Door Schedule

Schedules are tables used in construction drawings to organize extensive information about repetitive elements like doors, windows, finishes, and partitions in a clear, tabulated format. [16, 18, 23] While Division 08 specifications provide the technical quality requirements, and floor plans show the location, the door schedule is the primary location for a comprehensive list linking each unique door opening to its specific attributes.

What is the primary function of using a keynote system on construction drawings?

Answer: To reduce redundant text on drawings and link components to a legend or specification

A keynote system uses a numeric or alphanumeric code on the drawing to refer to a legend on the same sheet or directly to a specific section in the technical specifications. [2, 11, 24] This practice keeps the drawings clean and legible by minimizing lengthy notes while creating a direct, coordinated link between the graphic representation and the detailed written requirements.
