CHANGE ORDER
Reflection Bay Water Reclamation Facility Expansion
Date of Issuance: 04/10/2018 Change Order No.: 16
Contractor: Pepper Lawson Waterworks CoP Project No.: WW1405
Consultant: CDM Smith P.O.No.: 2016-00001153
Explanation:
This change order encompasses the following: The expansion project includes the rehabilitation of the Influent Lift Station
which required the cleaning and removal of the lift station solids. The original base bid requirement for the project required the
contractor to remove the following debris/sludge/grit material from the several structures including the existing Influent Lift
Station,and had included an extra work item for additional grit solids removal.
The contractor began removal of the contents of the existing lift station and encountered a much different material than
expected.After several days of removal operations,the City was notified of this condition.The material was not grit but rather a
grease material that would require enhanced removal and disposal techniques including more stringent safety equipment.The
City elected to have the contractor continue with the grease removal operations and track the costs on a time and material
basis to be assured of actual costs,due to this work effort being necessary and dependent on the Influent Lift Station work
progressing on schedule.The changed condition at the existing lift station could have possibly been the result of the extreme
flooding in Pearland due to Hurricane Harvey.The excessive amount of grease that was encountered was not anticipated by the
City or Design Engineer at the time of design.
The final summary of contents removed from the lift station and disposed of at the Republic landfill site: 49,880 Gallons
Grease;45.46 Tons of Solids;28 Containers used during the removal operation.
Description of Work
The result was an overrun the Base and Extra Work bid item amounts by$44,496.36 and$33,000.00 respectively.
The removal of the additional influent lift station material additional costs:
12 days of additional 3 man crew time: $63,675.25
Advanced personal protective equipment: $ 3,780.68
Additional waste container box rentals $31,383.70
Additional container cleaning fees $ 10,925.54
Additional disposal fees $44,308.00
Additional laboratory analyses $ 1,768.26
These additional costs total$134,193.76 from which a credit of$21,647.87 for sunk costs in mobilization was deducted bringing
the subcontract cost to$101,193.56 As un-scoped work,the contract allows the general contractor to pass on direct costs
with the subcontractor's markup plus his direct costs and mark up for overhead and supervision$30,122.34. This is shown on
page 2 of PLW's Summary Sheet Exhibit. This brings the total cost for this unknown condition to$131,315.90.

Re: Change Order# 16 Overview
Grease Removal at Lift Existing Lift Station CPR # 042
A. The original base bid requirement for the project was for the contractor to remove the
following debris/sludge/grit material from the following existing structures:
1. Existing Lift Station 10 tons
2. Existing SBR 115 tons
3. Existing ASHT 30 tons
Total of 155 tons for the entire project.
B. An extra debris/sludge/grit removal item #32 was also part of the contract.
Total 60 tons.
The contractor began removal of the contents of the existing lift station and encountered a much
different material than expected. After several days of removal operations, the City was notified
of this condition. The material was not grit but rather a grease material that would require
enhanced removal and disposal techniques including more stringent safety equipment. The City
elected to have the contractor continue with the grease removal operations and track the costs.
The changed condition at the existing lift station could have possibly been the result of the
extreme flooding in Pearland due to Hurricane Harvey. The excessive amount of grease that
was encountered was not anticipated by the City or Design Engineer at the time of design.
The brief summary of contents removed from the lift station and disposed of at the Republic
landfill site:
• 49,880 Gallons Grease
• 45.46 Tons of Solids and
• Total of 28 Containers used during this operation
This changed condition dictated that the removal & disposal operation was to be accomplished
on a T&M basis versus the originally planned base bid lump sum approach.
Subcontractor Cost Summary
• Grease Removal & Disposal Turnkey Operation $155, 841.43
• Original Base Bid Negotiated Credit $21,647.87
• Extra Grit Removal Bid Item $33,000.00
PLW Extra Supervision Labor $ 5,928.00
PLW Standard Insurance, Burden, OH & Fee $ 24,194.34
