Re: Project No. R15056 Port Arthur Main WWTP Improvements: Change Order No.003
Dear Mr. Matthews:
Included with this letter is Change Order No. 003 for the above referenced project.This letter is to serve
as a narrative for the items included in this Change Order No. 003 with supporting documentation
attached.
Item No. 1: Replace 4 Trickling Filter Effluent Butterfly Valves with Slide Gates
After Allco completed the demolition of the items identified on Sheet TF-M1: Trickling Filter
Demolition Plans at Trickling Filter"A",they attempted to close off the 30"Effluent Butterfly Valve
to assist with isolating and cleaning out Trickling Filter"A". It was discovered that all four of the
existing Butterfly Valves for the Trickling Filters were inoperable. This was brought up during a
Monthly Progress Meeting where it was requested of Allco to submit proposals for several
different options to replace the Butterfly Valves. All proposals were evaluated, and the decision
was made to proceed with replacing all four(4) Butterfly Valves with Slide Gates.Allco submitted
CP-010.1 for this unforeseen condition with a total cost of $104,340.00. Freese & Nichols, Inc.
agrees with their cost.
Total Cost: $104,340.00 Additional Days: 0 Calendar Days
Item No. 2:Add Expansion Joint to Aeration Basin Buttress Wall
Note 1 on Sheet AB-S1:Buttress Wall Plan and Sections states that the "basin shall be dewatered
during buttress wall and footing construction". Dewatering the basins is required to relieve the
pressure from the water in the Aeration Basin against the basin's wall that is cracking and bowing
outwards. After Allco had completed installing the rebar and formwork for the Buttress Wall, it
was discovered that one of the gates for the basin is not sealing making it not possible to dewater
the basin. Freese & Nichols, Inc. structural engineers revaluated the design and decided that it
would be acceptable to install the Buttress Wall without dewatering the Aeration Basin if an
expansion joint was added to the Buttress Wall. To add the expansion joint Allco will need to
remove a majority of the formwork that has already been installed, make modifications to the
rebar, reinstall the formwork, and then place the concrete for the Buttress Wall in two separate
placements. Allco submitted CP-011 with a total cost of $10,511.00 for all the labor and effort
required to add the expansion joint to the Buttress Wall. Freese & Nichols, Inc. agrees with their
cost.
Total Cost:$10,511.00 Additional Days:0 Calendar Days
PTR22379 T:\4.0 CONSTRUCTION\4.40 Contract Mod\4.43 Chg Orders\Change Order No.3
Item No. 3:Abnormal Weather Days from December 2022 through March 2023: 0 Days.
The contract documents designate a fixed amount of "Anticipated Bad Weather Delays" per a
given month and when the number of"Bad Weather Days", where rain "equals or exceeds 0.25
inches", go over the "Anticipated Bad Weather" days, that is defined as an "Abnormal Weather
Condition" and "the contractor is entitled to an equitable adjustment in the Contract Times".
From the month of December 2022, up through the end of March 2023, the project has
experienced 0 Abnormal Weather Days.
Total Cost: $0.00 Additional Days: 0 Calendar Days
To summarize, this Change Order No. 003 has an overall cost increase of$114,851.00 and 0 additional
calendar days to the contract time.
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.
