The intent of this letter is to notify you that Rone Engineering Services,
Ltd. (Rone) has been selected to provide construction materials testing and
inspection services for this project.
On February 13th, 2008 Rone personnel went to the 161 Denton Tap site
for the purpose of obtaining material samples for analysis. Three
aggregate samples were obtained and specific gravity tests as well as
absorption tests were run for comparison. Upon comparison of the test
results it has been determined that the relationship between the aggregate
samples is inconclusive. The specific gravities of the samples ranged from
2.149 to 3.467 and the Absorption ranged from 2.8% to 8.3%. Based upon
this data Rone will not be able to indicate whether these samples do or do
not come from the same stockpile. Should you have any questions or
concerns regarding our findings, please contact us at your earliest
convenience.
