NCIDQ Construction Documents and Details 2 — Questions and Answers
Question 1: What does 'AFF' mean as used in construction document dimensions?
- Above Finish Floor (Correct answer)
- Adjacent Framing Face
- Acoustic Finish Factor
- Allowable Floor Fixture
Correct answer: Above Finish Floor
AFF (Above Finish Floor) is used to denote the height of elements such as outlets, switches, grab bars, and shelving measured from the finished floor surface.
Question 2: In the CSI 3-Part Specification format, what is covered in Part 2 – Products?
- Materials, fabrication standards, acceptable manufacturers, and product properties (Correct answer)
- Installation methods, workmanship requirements, and cleaning procedures
- Scope of work, submittals required, and reference standards
- Testing, inspection, and performance verification
Correct answer: Materials, fabrication standards, acceptable manufacturers, and product properties
Part 2 of a CSI spec section describes the products themselves: acceptable manufacturers, material properties, dimensional tolerances, fabrication standards, and finishes.
Question 3: What is a 'shop drawing' and who typically prepares it?
- A detailed fabrication drawing prepared by a contractor or fabricator showing how they will build a component (Correct answer)
- A preliminary sketch prepared by the designer during schematic design
- A site plan showing construction staging areas
- An as-built drawing prepared after construction
Correct answer: A detailed fabrication drawing prepared by a contractor or fabricator showing how they will build a component
Shop drawings are detailed fabrication documents prepared by contractors, subcontractors, or fabricators showing dimensions, materials, connections, and installation details for specific components.
Question 4: What is the difference between 'NIC' and 'NTS' as used on construction drawings?
- NIC = Not In Contract (scope exclusion); NTS = Not To Scale (drawing notation) (Correct answer)
- NIC = No Interior Ceiling; NTS = New Tile System
- Both mean the same thing in different regions
- NIC = Nominal Interior Clearance; NTS = Net To Spec
Correct answer: NIC = Not In Contract (scope exclusion); NTS = Not To Scale (drawing notation)
NIC indicates that an item shown is outside the contract scope and not the contractor's responsibility; NTS notes that a drawing or detail is not drawn to an exact scale.
Question 5: Which detail type is most critical in specifying the transition between two different flooring materials?
- Transition strip or threshold detail (Correct answer)
- Expansion joint detail
- Control joint detail
- Partition base detail
Correct answer: Transition strip or threshold detail
Transition strip details specify the edge treatment, height change accommodation, and installation method at the junction between two flooring materials of different types or thicknesses.
Question 6: What is a 'punch list' in the context of construction administration?
- A list of deficiencies and incomplete items prepared at substantial completion requiring correction before final payment (Correct answer)
- The contractor's initial bid list of materials to be purchased
- A quality control checklist used during construction
- A list of shop drawings awaiting designer approval
Correct answer: A list of deficiencies and incomplete items prepared at substantial completion requiring correction before final payment
A punch list documents items that are incomplete, damaged, or not in conformance with the contract documents, compiled during the substantial completion walk-through.
