Gentlemen:
We have reviewed Proposal Request No. 2 dated 7/1/91. This document would
change the grading in the north end of the site, add a pipe inlet with some 12" RCP
draining into an existing catch basin, and add topsoil and seeding for the area.
The cost for this additional work would be as follows.
Item Quantity Unit Price Extension
Pipe
12" RCP 120 f t $20.00 $2
12" FES w/ Trash Guard 1 ea $675.00 $675.00
Tie into Existing C.B. 1 ea $200.00 $200.00
Grading
Excavation 3595 cy $2.35 $8,448.25
Topsoil 1613 cy $5.15 $8,306.95
Seeding 2 ac $525.00 $1,050.00
$21,080.20
We are assuming that this work would be done concurrently with the related work on
our present contract, that the excess soil would be placed relatively closely on the site,
and that no street repairs are included near the existing catch basin.
If there are any questions, please give me a call.
Sincerely,
Michael Moeller
Project Manager.
