~Dmar~Mr. Doyle:
I am transmitting one copy each of Change Order No. 1 for each
project for approval by the City Manager. These Change Orders
cover the use of Cement for subgrade stabilization in lieu of the
Lime which was originally specified. The end result of approval
of these Change Orders will be that a net savings of
approximately $14,072.10 will be realized by the City on the two
projects, while achieving a finished product which is equal to
that originally specified. The Change Orders have been executed
by both Ginn, Inc. and L. H. Lacy Co., and may be executed by the
City Manager without Council action since each is a reduction in
Estimated Contract Amount, and neither exceeds a change of more
than $ 10,000.00.
For your review we have attached supporting documentation upon
which our recommendation for approval of the Change Orders is
based. Time is of the essence, since the Contractor intends to
begin stabilization within the next couple of weeks and must have
a definite decision within the next few days in order to avoid
delays in completion of this project. I apologize for the short
notice, but we have been holding this item pending the
Contractor's receipt of test reports from his laboratory
confirming their verbal affirmation that the proposed subgrade
treatment will be acceptable. The report has just been received,
and the Contractor has asked us to proceed with processing the
Change Orders. As we had verbally been assured, the proposed
Cement Stabilization is acceptable, and therefore we recommend
proceeding with approval of Change Order No. 1 for each project
at this time.

If acceptable to the City Manager, please have him execute the
original Change Orders and return two copies: one for issuance
to the Contractor; the other for our files. You should file the
Original Change Orders with your Original Contract Documents.
Please call me if you have any questions.
Sincerely,
John C. Karlsruher, P.E.
Project Engineer
