Items recommended for inclusion with Change Order #1 are described in more detail as follows:
Item 1
In late October, 2020 Red River Construction Company, Inc. (RRC) was excavating between
Plant 3 Secondary Clarifiers 1 and 2 to locate the 39-inch aeration basin influent line that runs
between the clarifiers, and ultimately to locate the 18-inch return activated sludge (RAS) lines
that the project requires tie-in of, which are located at an elevation deeper than the aeration
basin influent line. The RRC excavator had not yet exposed the 39-inch pipe when water began
to well up from the pipe and fill the excavation. RRC immediately formed a berm around the
hole to contain the water, and began putting available pumps in place to dewater the hole, and
pump to the adjacent RAS splitter box. RRC enlisted a subcontractor to set up larger pumps
and piping required to bypass pump the flow from the primary clarifiers upstream of the aeration
basins, to the aeration basins. It was more than two weeks before RRC was able to stop flow
from the primary clarifiers, stop backflow from the aeration basins, and pump the excavation dry
to see the condition of the pipe. Photos are included that show the condition of the pipe, which
had seven large holes in the pipe crown within the length of the excavation alone. The bypass
pumping required attendance around the clock by RRC personnel.

RRC is requesting $233,487.81 and an additional 49 days of contract time for additional work
required to install the bypass pumping, attend the pumping activities, and for the cost of the
pumps, piping, and diesel fuel. The Engineer and RPR have reviewed the request, and have
found the cost and effort to be in line with what would be expected.
The following documents are attached to support Item 1:
1. Potential Change Order (PCO) #1 dated November 11, 2020 from Dean Porter of RRC
with the proposal and cost backup for the unforeseen work.
2. PCO #1 Response from Jason Anderson of Carollo Engineers with the Engineer's
response to the proposal.
Item 2
Through Specification Section 01500 —Temporary Facilities and Controls, the Plant 3
Improvement Project included a requirement for RRC to provide an on -site trailer for use by the
Engineer, with office furniture, and office equipment. It was decided after construction began
that a smaller trailer than specified would be sufficient, and that there would be no need for the
printer/copier, but that a single Dell Tablet Computer would be desired. Based upon this
information, RRC determined the savings resulting from the smaller trailer, and substitution of
the printer/copier with a tablet computer, proposing a credit back to the City of $2,616.66. The
Engineer and RPR have reviewed the proposal, and have found the credit to be in line with what
would be expected.
The following documents are attached to support Item 2:
1. PCO #2 dated December 4, 2020 as submitted by Carollo Engineers.
2. PCO #2 Response from Dean Porter of RRC with the proposal for the credit back to the
City.
3. PCO #2 Proposal Approval from Jason Anderson of Carollo Engineers.
Item 3
The Plant 3 Improvements Project did not intend any change to the influent piping to the
aeration basins, or any of the piping from the primary clarifiers. Based upon the conditions found
that required bypass pumping as presented in PCO #1, it was determined that the 39-inch C301
wire -wrapped pre -stressed concrete cylinder pipe (PCCP) pipe would need to be replaced to
allow the Project to continue. 39-inch PCCP is no longer manufactured by companies that
produce PCCP pipe. As such, it was recommended by the Engineer that the 39-inch PCCP pipe
be replaced with the readily -available 36-inch C900 PVC pipe. The City of Lubbock even had
enough 36-inch C900 PVC pipe in inventory that RRC would only need to purchase the ductile
iron fittings required for bends, and replacement of the wye where the 30-inch PCCP pipes from
the two primary clarifiers join.

Page 3
Given the condition of the 39-inch PCCP pipe, and given that the 30-inch PCCP pipe from each
primary clarifier was also 50 years old, the Engineer and Contractor both recommended
replacing the pipe all the way back to each primary clarifier. This pipe replacement would
ultimately reduce the cost and time required, as a fitting allowing transition from C900 PVC to
PCCP would be very expensive and have a very long lead time. Therefore, RRC also
purchased the fittings and C900 PVC pipe required to completely replace the old PCCP pipe
between the primary clarifiers and the aeration basins.
The cost of purchase and installation of the new C900 PVC piping and fittings totals
$370,264.99. However, there is $209,400 of 24-inch ductile iron RAS piping in the RRC
Schedule of Values that will no longer be required once the new 36-inch C900 PVC pipe is in
place. With the credit for the 24-inch RAS piping, RRC is requesting $160,864.99 and an
additional 42 days of contract time for the cost and effort required to replace the PCCP pipe with
C900 PVC pipe. The Engineer and RPR have reviewed the proposal, and have found the cost
and effort to be in line with what would be expected.
The following documents are attached to support Item 3:
1. PCO #3 dated December 8, 2014 as submitted by Dean Porter of RRC with the proposal
and cost backup for the unforeseen work.
2. PCO #3 Response from Jason Anderson of Carollo Engineers with the Engineer's
response to the proposal.

The Contractor proposes to make the following additions, modifications, or deletions to the Work described in
the Contract Documents:
Initial Bypass Pumping & Setup thru 111712020
During our process of field verifying the piping for the project, the 39" primary clarifier effluent line blew out while we
were digging up the 18" RAS line at the secondary clarifier #2. We immediately began a program of pumping out the
area to try to find out the problem. Unfortunately, the plant had no where to relocate the flow and we set up a bypass
system to help. The initial findings were that the 39' line had deteriorated in the top section of the pipe and a serries of
holes were found. Bypass pumping was not part of this contract nor was any work on the 39" line. Therefore, we feel
this is a change in conditions for the project and the costs thru November 7th were as follows:

Proposed Design Change Summary:
Specification Section 01500 - Temporary Facilities and Controls, Part 1, 1.12 Contractor Field Offices and Sheds, C.
Engineers field office specifies the requirements for a 10 ft by 46 ft trailer for use by the Engineer in the field, including
janitorial services, office furniture, refrigerator, etc.
In this same section, 1.13 Field Office Data Service and Equipment specifies Internet service requirements, and provision of
a printer/scanner.
In lieu of the larger trailer, it is acceptable to the Engineer to provide a much smaller trailer as readily available. In lieu of the
printer, the Engineer requests a single Dell Tablet Computer be provided. This computer will remain the property of the
Engineer/City of Lubbock. The specifications for this tablet are attached.
The Engineer requests a proposal for the Dell Tablet Computer, and a credit, as appropriate, for the reduced requirements
specified in Section 01500 1.12 and 1.13.

The Contractor proposes to make the following additions, modifications, or deletions to the Work described in
the Contract Documents:
39" & 30" Pipe Replacement
Replace 39" Primary Effluent In the Aeration Basin Gallery thru the 39" wye and to the Primary Clarifiers via 30" PVC.
This is based on relocating tee in the gallery and rotating it toward the north wall including reusing the existing piping.
A new pipe from the tee thru the north wall will be installed in a cored hole thru the wall. Wall sealed with Linkseals.
An aluminum stairs over the pipe will be installed. The 39" pipe will be replaced with 36" PVC pipe from the City.
New fittings with MJ restraints will be Installed by Red River. Pipe will reduce after the Wye down to 30" PVC. Pipe will
have a gradual slope from the Gallery pipe to the wye. Final elevation changes to Clarifier outlets will be adjusted by 45
bends. Existing 39" & 24" piping under transformer pads will be filled with flowable fill. The 24" will be capped/plugged
with concrete. Most of the rest of the 39" & 30" pipe will be demoed during replacement. The 24" RAS line that was to
be demoed and filled has been deleted. The 12" RAS Pump Discharge lines will connect directly to the new 36" pipeline.
