MEMO TO: HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL
FROM: BRUNO RUMBELOW, CITY MANAGER���'
MEETING DATE: NOVEMBER 3, 2009
SUBJECT: CHANGE ORDER # 2 EULESS GRAPEVINE / STONE MYERS
PARKWAY CONSTRUCTION PROJECT
RECOMMENDATION:
City Council consider approval of Change Order#2 to the Euless Grapevine/Stone Myers
Parkway Construction Project in an amount of $22,119.05, authorizing staff to execute
Change Order#2, and take any necessary action.
FUNDING SOURCE:
Funds are available in the following accounts:
• Utility Bonds Account# 200-48930-534-1-000021WA
• GO Bonds Account# 178-78106-012
BACKGROUND INFORMATION:
Change Order# 2 addresses the following items:
Future Driveway Connections at the First Baptist Church site. (GO Bonds)
280 SY Concrete Driveway Apron $16,800.00
On a project of this type, we normally construct the driveway aprons to the abutting
properties with the roadway pavement construction. The church did not have the two
driveway locations tied down at the time of project bidding but have been able to provide us
the locations since then.
Replace Lime Stabilized Subgrade with Cement Stabilized Subgrade (GO Bonds)
26,586 SY Subgrade Treatment ($ 44,582.10)
Initial pavement design anticipated majority of subgrade to require lime stabilization based
on soil samples. More through analysis of soils after the entire roadway route had been
exposed and many more soil samples had been taken reveals a much higher percentage
of the soils along the route require cement stabilization rather than lime. This is a less
expensive process that is used for soils with a much lower potential for expansion.

Water Line Lowering (Utility Bonds)
700 LF 12" Waterline with Appurtenances $ 49,901.15
The construction of the Euless Grapevine Road segment of the project required that the
roadway profile be lowered through a vertical curve north of the Big Bear Creek bridge.
This profile lowering necessitated the lowering of the existing 12"waterline adjacent to the
west curb of the roadway for a length of 700 ft.
Staff recommends approval.
