the mobilized capacity was 565 kips distributed

Figure 5 shows a summary of the
dynamic testing performed on contracts
402 and 605. Sixty-one initial drive tests
and 75 restrike tests were performed for
contract 402, totaling 56 days of dynamic
testing. For Contract 605, a total of 73
initial drive tests and 92 restrike tests were
performed over 90 days of testing. Figure 5
also shows approximate costs of performing
dynamic testing remotely versus the
cost of having a testing engineer on site for
each test. The cost savings resulting from
performing the testing remotely ranged
from 28 to 35 percent, even before including
construction cost savings realized from
expedited results. Having results submitted
on the same day as the testing allowed construction
to continue without delays.
In quoting the PKF personnel’s view
of remote testing, “Overall, the SiteLink
program was a great success. The means of
testing on the site at any time is remarkable
for the rapid changes we are faced with in
construction. The SiteLink equipment was
nothing more than a mobile computer and a
few sensors, and the program was very user
