At last week’s HMMH Annual Stockholder Meeting, the Founders of HMMH presented their award for excellence “In recognition of outstanding performance on a project that was uniquely challenging, technically innovative, and resulted in proven client satisfaction.”  The award was given to the project “On-Board Sound Intensity Measurements to Evaluate the Noise Reduction of Pavement Grinding, I-195, Providence RI.”  The Project Manager was J. Eric Cox, Principal in Charge was Christopher W. Menge, and the team included James E. Ferguson III, and Ryan Cranfill.

The purpose of the project was to prove that adequate sound reduction of I-195 road noise had been achieved by diamond grinding of the concrete bridge deck, mainline roadway, and on/off/interchange ramp surfaces. Grinding operations were conducted to reduce noise generated by traffic traveling over transverse tining. The “OBSI” measurements had to be made on 19 ramps and roadway sections, in the wee morning hours when little other traffic was using the roadways.  Client David Freeman of Maguire Group, Providence, RI said that “it worked out really well and the results [of the measurements] were used to justify a bonus to the contractor.”
