NCIDQ IDFX EXAM 2023 UPDATE The principal consideration in acoustic control in large spaces is the sound absorptive quality of the ________. - Answer-Ceiling [Noise reduction within a space: In larger rooms, ceiling treatment is most effective, while in smaller rooms, wall treatment is more effective.] These are part of the HVAC system used for return air and generally have no movable parts or slats for adjustment. - Answer-Vents [Source: Qpractice NCIDQ Exam Guide, Structural, Mechanical and Plumbing Systems -Diffusers have direction fins at different angles (sometimes adjustable) to distribute the air throughout the space. -Registers (in the floor or wall) can be open, closed, or adjusted somewhere in-between. -Grilles often used for return air have no movable parts or slats for adjustment.] In a new lifestyle hotel, the spa suites will have 4 poster canopy beds. How far away from the sprinkler heads should the beds and panels be? - Answer-20 inches [The canopy would be considered an obstruction to discharge as defined in NFPA 13, 8.5.5 Obstructions to Sprinkler Discharge, which restricts continuous or noncontinuous obstructions less than or equal to 18in (450mm) below the sprinkler deflector.] What are the variables of noise reduction between two rooms? - Answer-The three most important variables are the wall's stiffness, the transmission loss, and the common area between rooms. A client has requested that special security protection be provided for critical paper files containing corporate trade secrets, but at a reasonable cost. In designing the file room, the interior designer should suggest: - Answer-Card readers at the doors leading to the file room [Source: Interior Construction Detailing for Designers, Hardware, Electronic Hardware Card readers would be the most cost-effective solution because they could provide access control as well as notification if there was an attempt at unauthorized entry.] An air handler access panel should measure a minimum of: - Answer-2' x 2' (600 mm x 600 mm) [Source: Interior Construction Detailing for Designers, Ceilings -Building codes require that access panels be provided to certain components of the mechanical and electrical systems for anything that has to be inspected, adjusted or repaired. Access doors are typically small steel doors with frames that are opened by using a thumb turn or a key. -Per the NCIDQ instructions in a typical commercial reflected ceiling plan demonstrating integration of building systems, the candidate is to place a minimum 2' x 2' (600 mm x 600 mm) access panel for the air handling unit where required.] A client has requested that special security protection be provided for critical paper files containing corporate trade secrets, but at a reasonable cost. In designing the file room, the interior designer should suggest: - Answer-card readers at the doors leading to the file room [Source: Interior Construction Detailing for Designers, Hardware, Electronic Hardware Card readers would be the most cost-effective solution because they could provide access control as well as notification if there was an attempt at unauthorized entry.] All buildings move to some extent, what type of joint is used accommodate large movements and are typically part of the building design? - Answer-expansion joints [All buildings move to some extent. Interior construction must take into account the possible movement of the building structure. Slip joints and relief joints should be used whenever minor building movement is expected. Large movements are accommodated by building expansion joints, but these are usually already in place as part of the design of the building.] Which type of door typically used in commercial construction contains one or more glass lights? - Answer-sash [Metal doors and frames (often referred to as hollow metal) are seldom used for residential construction. They are, however, frequently used in commercial construction because of their durability, security, and fire-resistive qualities. The three most common types of metal doors are flush, sash and louvered. Flush doors have a single smooth surface on both sides. Sash doors contain one or more glass lights. Louvered doors have an opening with metal slats to provide ventilation.] Which of the following would be the correct way to number a fire protection plan in a set of construction drawings for a high rise office space? - Answer-5FP4.1 [In order to provide a logical way to organize and refer to the drawings a system of numbering must be established. There are several ways to do this. The simplest method uses single numbers beginning with 1. -For larger drawing sets where consultants are involved, numbers are preceded with a capital letter designating the discipline involved. "FP" is used for fire protection. -For large projects the drawings within each discipline can be grouped; for example: floor plans could be group 1, The group number is followed by a decimal point then the sequential numbers start with "1", example FP2.1 (fire protection group 2 page 1) -For projects in a high rise with different sections the number is proceeded with the floor number. For example 5FP4.1 (5th floor fire protection group 4 page 1).] Which method of information gathering entails using photographs from different angles to create a three-dimensional model? - CONTINUES...
