ST 99-02 A, West Sandy Lake Rd - Work Activity Update
Week of 2/20 to 2/24
1. It was discovered that the proposed 33" RCP at Oakbend Subdivision is in conflict with the
existing 8" water main on Oakbend Ln. This information has been forwarded to Matt Atkins.
I am discussing with him the possibility of lowering the proposed storm drain elevation to
avoid this conflict. *
2. It was also discovered that the existing 10" fire line lead to the existing fire vault and
domestic meter conflicts with the 30" RCP at sta. 47+00. The plans called for a ring
connection on the 10' fire line to be tapped to the existing 24" (the location is in the ROW in
from of Coppell Bible Fellowship). It is my belief that this can be handled with a different
configuration which would result in a cost saving and construction time savings. However,
this connection will require a shut down of approximately 6 hours to make the reconnection
and bring the fire line and existing domestic water on line. *
3. Contractor relocated the existing 1" water service east of Oakbend; relocated and tapped to
the existing 8" waterline on Oakbend. This item could also generate cost savings to us and
construction time savings by simply relocating this irrigation tap at the suggested location. *
4. Comractor is laying 30" RCP from sta. 12+50 west to sta. 15+00.
5. Station 42+66 fire hydrant relocation - the relocation is being done off the 12" water main on
the west side of Freeport Pkwy. I field-approved the relocation of the 6" fire line tap to the
new 12" water main along the west side of Freeport, which will also result in cost and time
savings. *
* These suggested field changes should not require change orders, the cost savings could be
applied to other appropriate areas during the construction of this project.
