1 SUBJ: Approval of Change Order No, 1 , Chanhassen City Hall
Addition and Chanhassen Fire Station Addition and Remodeling
IIThe Fire Station addition and remodeling and the City Hall addi-
tion have been moving ahead, but somewhat behind schedule. At
1 the present time, both projects are approximately 3 weeks behind
schedule due to a combination of bad weather , i .e. wind, and a
delay in the steel necessary for construction. The attached
Change Order No. 1 is a summary of miscellaneous individual
1 change order items which have accrued to date during the
construction. The attachment to the change order defines in
detail the specific items which comprise this change order. The
1 net impact is an addition to the contract in the amount of
$7 , 611 . 43 for the Fire Station and $4 ,052 .00 for City Hall . The
total amount for both projects is $11 , 663 . 43 .
ilAs you will note from the attached letter from Jack Anderson,
this change order represents approximately 2 .5% of the completion
amount to date. He indicates that this is considerably less than
IIthe 7% to 10% which is typical for a project of these dimensions.
There are predominantly three reasons why these change orders are
II made necessary and include: 1) refinement of design in order to
meet Codes; 2) necessary work not bid because of hidden (not
observed) items; and 3) items to better suit owner' s needs.
There will be additional change orders as we progress through
these projects; however, I would anticipate that they would not
exceed the contingency that was budgeted.
II am therefore recommending that Change Order No. 1 be approved
in the amount of $11 , 663 . 43 .

Dear Mr, Chaffee:
Enclosed please find a copy of Change Order Number One for the City Hall and Fire I
Station. The copy consists of the AIA document form filled out, an attachment explaining
each item within the Change Order and attachments with Contractor's backup information. I
As per our conversation it is interesting to note that the projects are about$470,000
complete and this Change Order amounts to about$11,000. At about 2.5%the amount of
I
change orders at this time is considerably less than the 7%to 10%which is typical for
projects such as these.
If you have any questions please call. Thank you.
