Full Breakdown
Chapter 311 gives construction a hybrid treatment: broadly exempt from the general decibel limits, but boxed into fixed hours. Section 311-4C exempts construction and demolition activities from the sound level limits in Tables I, II and III, but only except as provided for in Section 311-9, which is where the real restriction lives. Section 311-9C states the operative rule limiting when work may occur, and it also requires all motorized equipment used in construction or demolition to be operated with a muffler and/or sound reduction device at all times.
In practice that means a contractor can run loud equipment at any level during permitted daytime hours, but during the barred night and early-morning window, work is allowed only if it meets the same numeric decibel tables that apply to ordinary noise sources, such as the 50 dB outdoor residential nighttime limit in Table I. "Emergency work" is separately defined in Section 311-2 to cover actions needed to restore essential services such as water, gas, electricity, sewer or public transportation, or to abate a declared emergency, and that work is exempt from the hour restriction entirely.
Violations & Fines
A contractor working outside the permitted hours, or without required mufflers, is enforced under Section 311-11: the Noise Control Officer or Investigator issues a notice of violation or notice of penalty assessment, and civil penalties reach the state-law maximum under N.J.S.A. 40:49-5, stated as $2,000 per offense as of December 2014, with each day of continuing violation a separate offense.
