A 5.75m high noise barrier is used to attenuate sound from a roadway adjacent to a residential subdivision. The height of the noise source is 1.25m and the height of the receiver is 2.25m. The distance from the noise source to the noise barrier is 22.00m. The distance from the noise barrier to the center of the rear yard of the residences is 11.00m. Determine the Path Length Difference in meters (accurate to 4 dec.pl.) that is created by the noise barrier.

Pricing Construction Equipment

Pricing construction equipment means estimating the cost of operation of all the construction equipment used in a construction project. The pricing is done based on two factors – ownership cost and operating cost of the equipment. Thorough knowledge of the ownership and operating costs is necessary for proper project management and executing profitable construction.
