Follow-Up with AMEC
The information presented during the delegation on this issue on February 11, 2013 did
not paint a positive impression of AMEC’s work. As a result staff met with a senior
AMEC representative on February 21 to review the concerns expressed by the
complainant and to determine if the study was completed negligently. AMEC Has asked
to go on record with the following statement:
“Thank you for giving me the opportunity to meet with you yesterday to discuss
the general premise and results of the vibration monitoring presented in our
Report SW0512033 dated 30 November. It was concluded that the work was
carried out professionally and as per the expected and agreed scope. The
magnitudes of the vibrations measured were much lower than the level at which
structural damage could be expected. An exhaustive long term vibration study to
determine the very low threshold levels of vibration perceptible by humans would
be relatively much more expensive than the current study.
Again, thank you for giving AMEC the opportunity to be of service to Lambton
Shores.”

Each of the four concerns presented in the delegation were provided to AMEC for
comment, and the information below was provided respecting each concern:
1. The AMEC representative confirmed municipal staff’s statement that the test was
representative as the load on the road will never be greater than when two trucks
pass by the same location at the same time, regardless of traffic volume.
2. As above, AMEC confirmed that, in their opinion, the study was representative
based on the scope requested. The scope of the project was to confirm if surface
vibrations were caused by the roadway.
3. The AMEC representative confirmed that monitoring discs were placed directly
on the ground and sandbags were then placed on top of the monitors. This is
standard practice to ensure the disc is in direct contact with the ground with the
sand bag preventing the disc from moving during the test. Photo documentation
of the testing shows this to be the case.
4. AMEC confirmed their staff is qualified to complete this work, and offered the
company’s curriculum vitae for review should Council desire it.
In addition to the above, the senior AMEC representative provided the following
information that is useful for consideration 116 of this issue:
