Re: Project No. R15056 Port Arthur Main WWTP Improvements:Change Order No.004
Dear Mr. Matthews:
Included with this letter is Change Order No.004 for the above referenced project.This letter is to serve as a narrative
for the items included in this Change Order No.005 with supporting documentation attached.
Item No. 1:Additional Piping and 10"Pump Reroute @ MOLS
After Allco completed the exploratory excavations at the Main Outfall Lift Station (MOLS), it was realized
that the underground piping was not per the record drawings that the design was based on along with
discovered two underground concrete junction boxes. These unforeseen conditions require additional
material to route the bypass header manifold piping around the underground concrete boxes and additional
piping to reach the existing 30" force main.This line item also includes the cost to reroute the discharge
piping of the existing 10"Gorman Rupp pump that was at the MOLS to the existing 36"Force Main through
the dry well.
Total Cost:$246,607.00 Additional Days:0 Calendar Days
Item No.2:36" Line Stop and HDPE Bypass Piping @ WWTP
The IFC plans called for the 36"Force Main from the MOLS to be temporarily bypassed through the existing
30" Ductile Iron Pipe. After completing the exploratory excavations at the MOLS it was realized the 30"
Force Main is Bar Wrapped Concrete Cylinder Pipe, not Ductile Iron, and could not handle the capacity of
the bypass pumps. In order to continue the work at the WWTP,a line stop had to be installed at the 36" DI
influent pipe to reroute the flow through 440 LF of 24" HDPE.
Total Cost:$143,194.00 Additional Days:0 Calendar Days
To summarize,this Change Order No.004 has an overall cost increase of$389,801.00 and 0 additional calendar days
to the contract time.There will be a subsequent change order for the additional days incurred for these changes.
I hope the above narrative, along with the included supporting documentation, provides adequate information to
be able to process this Change Order. Please don't hesitate to reach out to me if you need any further explanation
or backup documentation.
Sincerely,
Rami Abusheikh, P.E.

Date: January 25,2024
To: Ronald Burton, City Manager
From: Calvin Matthews, P.E. Water Utilities Director
RE: Emergency Repair on Main Wastewater Treatment Plant(WWTP) Improvement
Project- Main Outfall Lift Station(MOLS) Change
Due to the field conditions varying from the historical data on the Main Wastewater Plant
Improvement Project,the contractor found the critical condition of the existing sewer force main
which will cause the completed failure on MOLS. The emergency changes are needed
immediately including an additional 30" ductile iron pipe and fittings underground,to construct
the bypass pumping manifold, additional fittings to build the 30" line around the discovered
junction boxes, remove failed pump No. 3 from the dry-well and pipe temporary 10" Gorman
Rupp pump to discharge header to maintain lift station capacity, a special connection must be
made at the lift station site and the wastewater treatment plant site, the 24" bypass, and 440 LF
of 24"HDPE(Attachment). The changes will also result in the construction time extension.
The total expenditure for the repairs was expected to be around$389,801.00 and will be charged
under the CIP Account No.405-40-000-8516-00-00-000, No.WS0023.
I,Pamela Langford on behalf of Ronald Burton,hereby approve the emergency repairs by ALLCO,
LLC.

Re: Port Arthur WWTP—MOLS changes
Dear Calvin:
Please find below, a description for the required changes to the project due field conditions varying from
the historical data:
1. The existing 30"force main is not located as shown on the contract drawings. It also is constructed
of concrete cylinder pipe, not ductile iron as shown. This difference requires additional 30"ductile
iron pipe and fittings underground, in order to construct the bypass pumping manifold.
2. There was also found, 2 large existing buried concrete junction boxes not shown on the plans. This
required additional fittings to build the 30" line around the junction boxes.
3. Removed failed pump No. 3 from drywelI and piped temporary 10" Gorman Rupp pump to
discharge header to maintain lift station capacity.
4. In order to connect the 30"ductile iron pipe to the concrete cylinder,a special connection had to be
made at the lift station site and the wastewater treatment plant site.
5. Upon start up of the bypass pumps this week, a rupture occurred on the concrete cylinder pipe in
the road leading to the lift station. Upon investigation, it has been found that the 30" concrete
cylinder pipe force main is not structurally sound and will not be able to be used for bypass pumping
as per the contract drawings.
The pricing for the above work is as follows:
Material $ 143,921.00
Labor 33,388.00
Payroll Taxes 16,026.00
Equipment 21,106.00

As discussed on the jobsite, the revised plan was to install a 36" line stop and a 36"x 18" hot tap, in order
to bypass to allow for 2 tie-ins. We have found that a 36" line stop has a built-in 24" bypass, so a separate
hot tap will not be required. We have included 440 LF of 24" HDPE to be run on top of the ground to the
existing headworks. The pricing for this work is as follows:
Material $ 41,059.00
Labor 11,120.00
Payroll Taxes 5,338.00
Subcontract—line stop 55,000.00
Equipment 12,000.00
$ 124,517.00
Overhead& Profit 18,677.00

Let me know if you have any questions.
