The following change is hereby made to the contract for the above project:
Description of Change
,
Transition sanitary sewer laterals were required for this project due to DIP in the original design. A new
line item for standard sewer lateral in the roadway was not established in the original contract. The new
line item is being established for the purpose of providing a standard sanitary sewer lateral in the roadway
for the Kemp Drive project.

SUBJECT: Augusta Capital Improvements Program
Project 50040-Kemp Drive Sanitary Sewer hnprovements Project
Request for Administrative Change Order Number One
As discussed on Friday, May 24, 2002, it is necessary to request an administrative change order for
the Kemp Drive Sanitary Sewer hnprovements Project that will change most of the originally bid
Ductile Iron Pipe to PVC pipe. The justifications are as follows:
· The cost of the ductile iron piping (DIP) in relation to the PVC piping allows a cost savings of
$8948.28 by using PVC piping and eliminating the DIP from the project.
· DIP with special epoxy coatings required for sewage, creates a potential delay for the project due
to the need to send the DIP to a coatings manufacturer.
· Maintenance of the DIP will be more labor intensive than maintenance ofPVC piping, which
will drive future maintenance costs higher.
· Maintenance material costs for DIP will be higher than maintenance material costs for PVC
pIpmg.
· Transition couplings from ductile iron to PVC service cleanouts will hamper low-pressure air
testing per Uni-Bell PVC Pipe Association testing requirements. Low-pressure air testing of
completed sewer systems is required by The Augusta Utilities Department Standards and
Specifications. Air testing of the completed system is critical to ensure the piping will not allow
infiltrationlexfiltration of the line. By utilizing PVC piping materials the transition coupling
required for DIP to PVC transition will not be needed, and low pressure air testing can be
performed as per AUD Standards and Specifications.
· Due to numerous underground utilities in the project area, the path for the DIP placement is in
close proximity to an Atlanta Gas Company gas main. Due to electro-magnetic fields created
by these two systems being in close proximity to one another, an explosion hazard and corrosive
situation can be minimized by utilizing PVC piping.
