Re: Wagon Wheel Ranch Elevated Storage Tank
Change Order No. 1
Dear Mr. Griffin:
As we discussed, we have modified Change Order No. 1 to you contract with Landmark Structures, Inc., to
eliminate connections to the existing distribution system on the Sandy Lake Road Water Line segment across
the frontage of the Forest Cove Addition. Further, we have included a lump sum deduct for allowing the
contractor to paint the tank bowl prior to final assembly of the roof plates. One copy of the change order is
enclosed for your review. We have also forward a copy to the contractor.
We have not yet received a price proposal for the extra work. However, our opinion of probable construction
cost for this change order is in the range of $240,000 to $250,000. This figure does not include the deduction
for the revised tank painting procedure and represents approximately 11 percent of the original contract
amount. A detailed copy of our opinion along with the revised construction plans are enclosed for your
review.
We understand your schedule for completing this change order paper work is May 1, 1998, and are working to
have all issues resolved ahead of that date. We are available to discuss this project further at your
convenience.

CITY OF COPPELL, TEXAS
WAGON WHEEL RANCH ELEVATED STORAGE TANK
Project No. WA-96-01
Bid No. Q0198-03
CHANGE ORDER NO. 1
A. INTENT OF CHANGE ORDER
The intent of this change order is to modify the provisions of the contract entered into between the City of
Coppell, Texas and Landmark Structures, Inc., 1665 Harmon Road, Fort Worth, Texas 76177, for
construction of the Wagon Wheel Ranch Elevated Storage Tank, dated March 10, 1998.
B. DESCRIPTION OF CHANGE
1. At the pre-construction conference, Landmark Structures requested permission to paint the tank bowl
after it is assembled on the ground and before it is hoisted into position. This is contrary to the project
requirements for surface preparation of the tank bowl as outlined in SC. 10.C. Surface Preparation, of the
Special Conditions to the project specifications which requires the tank to be fully assembled prior to
painting. The City of Coppell hereby modifies that requirements of SC. 10.C and will allow exterior and
interior painting of the tank bowl once it is assembled on the ground and before it is hoisted into its final
position on the tank column. The interior and exterior paint systems on the tank bowl are to be re-
blasted and coated to a point no less than 2 -feet from the tank bowl/roof plate seam once the roof plates
are welded into position. This change order provides for a lump sum deduct from pay item number one
for consideration of procedural changes in the application of the paint coating system.
2. As directed by the City of Coppell, 1,940 linear feet of 24-inch waterline is to be constructed along
Sandy Lake Road from Coppell Road to Whispering Hills Drive. The extra work is identified on the
Sandy Lake Road Water Line Plans, sheets 7, 8, and 9, marked "Wagon Wheel Ranch, Change Order
No. 1, and dated April 24, 1998. The referenced construction plans are now a part of this project. This
work is added in an effort to coordinate with construction for a new development in the vicinity.
