NEBB S & V PROCEDURAL STANDARDS SECTION 3 RESPONSIBILITIES b) Develop a project schedule, with the input of the NEBB Certified S&V Firm that coordinates the work of other disciplines and provides adequate time in the construction process to allow successful completion of the S&V work. c) Notify the NEBB Certified S&V Firm of all schedule changes. d) Ensure that the building enclosure is complete, including but not limited to: all structural components; windows and doors installed; door hardware complete; floor and ceilings complete; stair, elevator and mechanical shafts complete; roof systems complete, all plenums sealed; etc. e) Ensure that all necessary building systems are complete and are operating in a safe manner. f) Complete the installation of permanent electrical power systems serving the building systems. Such electrical systems shall be properly installed in accordance with all applicable codes to ensure the safety of all construction personnel. g) Perform start up of all building systems in accordance with manufacturers' recommendations. h) Complete the installation, programming (including design parameters and graphics), calibration and startup of all building control systems. Verify that the building control system provider has commissioned and documented all building control work. i) Complete all TAB related work. 3.2.3 NEBB CERTIFIED S&V FIRM RESPONSIBILITIES The NEBB Certified S&V Firm shall: a) Follow the current NEBB standards and procedures when performing the S&V work. b) Communicate on a regular basis, through proper channels, items pertaining to design, installation or function that prevent the NEBB Certified S&V Firm from achieving completion of the S&V work in accordance with the current edition of the NEBB Procedural Standards for Measurement of Sound and Vibration. c) Perform the required S&V measurements. d) Publish a NEBB Certified S&V Report of final conditions that accurately reflects the sound and vibration measurements taken on the required building systems. 12
SECTION 4 STANDARDS FOR INSTRUMENTATION AND CALIBRATION 4.1 MINIMUM INSTRUMENTATION A NEBB Certified S&V Firm will use a variety of instrumentation to perform the specified S&V measurements on a project. It is the responsibility of the NEBB Certified S&V Firm to provide appropriate instrumentation that meets the minimum requirements for use on a project. Instrumentation used on a NEBB project shall be in proper operating condition and shall be applied in accordance with the manufacturer’s recommendations. TABLE 4-1 lists the minimum instrumentation specifications that a NEBB Certified S&V firm shall utilize in the performance of all sound and vibration measurements. The NEBB Certified S&V Firm has two options relating to equipment and instrumentation requirements; 1) they shall either own and maintain the required instruments, or 2) they shall have access to the required instruments. In either case, the actual instruments used to perform all S&V work and measurements shall conform to the requirements of Table 4-1. Instruments shall be used in accordance with manufacturer’s recommendations. The most suitable instrument, or combination of instruments, should be employed for a particular measurement or reading. Some of the instrumentation identified in TABLE 4-1 is redundant for different applications, not all of these instruments are required to be owned / leased. The instrumentation required shall be based on each project’s requirements and shall be determined by the NEBB S&V Supervisor. The minimum instrumentation required to perform either sound or vibration measurements is as follows, Sound Level Measurements – the minimum instrumentation required to perform sound level measurements is: a. A traditional sound level meter with a full or third octave filter set, AND an acoustic calibrator. b. A real time analyzer with third and full octave capability, AND an acoustic calibrator. Vibration measurements – can be performed with a number of different instrument configurations, such as; a. A Sound Level Meter with a third octave filter set, a vibration integrator matched to that sound level meter, and an accelerometer. b. A Real Time Analyzer with third octave and/or narrow band FFT capability AND input capability for an accelerometer, and an accelerometer. c. A Vibration Meter and an accelerometer. d. A Spectrum Analyzer and an accelerometer. 13
