Dear Mike:
This letter presents segments of our revised proposed Change Order No. 2 (copy enclosed) to our
contract with Bean Construction Company. The only difference between this letter and my July
18 letter to you is the reduction in Item 3., f., "Dispose offsite brush & debris from BDD4 Exc.".
The revised amount is $3,000 instead of $30,000 in my July 18 letter. As I said there, these
Change Order segments are proposed by the City to help an early completion of the detention
basin, and to relieve BDD4 from the detail work of fine grading and inlet and piping work.
Change Order No. 2 Segments:
"2. Re-work existing E-Inlet and 60" CMP at southeast :comer of East Pond SOuth of Blue Line
(BDD4 area) by removing the upper 60" pipe and sealing manhole at the upper entry, salvaging
60 feet of the 60" CMP and with three new connection bands extend lower 60" to match
construction drawings, and clean manhole and grade outlet as shown on construction drawings.
Remainder of removed 60" CMP shaJl become property of the Contractor and shall be removed
from the site.
Amount of Item 2.
$11,609
3. Perform additional work south of the Blue Line (BDD4 area):
a) Finish grade 30' berm and construct berm drain swales 4690 LF~$3.50

TOTAL AMOUNT OF 2. and 3. (Above)
$711,921
In our pre-construction interlocal agreement last October, BDD4 agreed to accept performance
responsibility represented by cost estimates (copies enclosed) for these items that resulted in
approximately 47.6% (copy of calculation enclosed) of the total estimated cost of the respective
items.
Please consider assuming responsibility for 47.6%, or $34,234 of the total mount of these
Change Order No.2 segments of $71,921. (Clearing and disposal work already done by BDD4 has
been recognized. Only a small amount remains to be hauled off site.) This would be in return for
relief from performance of those tasks.. In our opinion, this change order will result in an earlier
completion of SWEC Detention Basin, thereby better meeting expectations of citizens, and will
remove from the responsibility of BDD4 the fine grading and detailed concrete and inlet and pipe
setting work entailed.
An early reply would be greatly appreciated.
