Alpha Project No. 92159-~
Based upon our recent conve=sat£ons, we understand that
f~11 w~l! be required fo~ the above referenced project. Or1 June
10, 1992, a member of our staff received a sample of fill from you~
off~ce for visual evaluation as use Ecs f~11. ~e s~ple consis~
cE gray shaly l~mes~one. In our opln~on, ~he ma~e=~al could be
used for f~l for th~s p~oJect. We recom~nd tha~ ~he l~s~one
be processed ~uah that all ~nd~vidual rock pieces are less than 6
{nches in d~mens~on and the sufficient f~nes are creat~ to f~11
all voids ~tween ~he large= =~k p~eces. ~e rock fi~l should be
comp~ct~ to at least 95 percent of s~da=d P~oc~o~ maximin
density. ~e compacted mo~gtu~e content of limestone {s no~
oon8Lde=~ crucial with r~ard ~o proper performance. However,
may be possible to minimize the compac~ve effor~ required to
achieve the m~nimum compaction o=~er~a ~f ~he mater~alts moisture
content ~ur~ng placement ~s w~thin three percent of optimum,
Add~tlonal~y, no rock fill should be used within Ift below
~om of floor slabs.
we appreciate the opportunity to be of service ~o you on
project. If we can be of further assistance, please contact our
