Notice to Property Owners Near Structural Monitoring Program

The following notice has been sent to property owners adjacent to the Boardwalk advising of the Structural Monitoring Program required by the U.S. Army Corps of Engineers in conjunction with the upcoming beachfill project. 

Great Lakes Dredge and Dock Company, LLC (GLDD) has been awarded the contract from the US Army Corps of Engineers (USACE) to conduct beachfill and dune reconstruction operations from Brigantine Inlet to Great Egg Harbor Inlet, Absecon Island, New Jersey. Work on the beach with construction equipment will begin in September 2020. Construction work will be on-going from September 2020 – March 2021 and is expected to continue 24-hours a day, seven days a week.  

As part of this contract, a structure monitoring program (SMP) will be conducted during construction. SSI, INC. (SSI) will perform this structure monitoring. SSI is an independent consulting firm specializing in the measurement and control of construction vibrations. SSI’s role in the project is to conduct exterior only pre-construction surveys of the buildings and improvements that are adjacent to the project and to implement seismic monitoring during construction. 

The USACE has specified vibration control limits that will minimize the potential for any impact on your building from vibrations produced by the operation of construction equipment on the beach during the project. The vibration control standard for this project is based on decades of research and is accepted globally as a safe standard for the protection of drywall in residences from vibration impacts. However, even safe levels of vibration can be noticeable to occupants of nearby structures. This perceptibility is quite normal and is no cause for alarm. 

If you have questions or concerns regarding this project or the structures monitoring program please call Mr. Patrick Hastings of SSI, at 1-888-250-6566 or Mr. Mandeep Talwar of the USACE, at 215-313-1150.  If you do not want to be included in the SMP, please contact us.
