Professional Services Contract Amendment
Bailey Water Plant Improvements
Date of Issuance: 07/19/2021 Amendment No.: 3
Consultant: Enprotec/Hibbs&Todd CoP Project No.: WA1901-Enprotec
P.O. No.: 2019-00000747
Explanation:
This change order encompasses the following: Due to the extensive landscaping in front of the Natatorium and Recreation
Center, staff pursued alternate construction methods to minimize impact and restoration costs associated with conventional
open-cut method. However,the nature of gravity sanitary lines requires the pipe be sloped continuously to keep waste moving
through the system,which could only be guaranteed in a costly jack-and-bore installation. Cost analysis performed throughout
design showed an imbalance in value to pursue the gravity main installation due to the necessary depth and grade requirements
of the line. By modifying the design to incorporate a shallower force main and a new lift station to serve the backwash pond,
the motor control lab building on site, and future Fire Station 7,the construction cost was reduced by$1.3 million
The addition of the Magnolia flows to Bailey results in necessary pump and electrical upgrades at the Magnolia site to account
for the modified treatment configuration. The Bailey and Magnolia sites need the appropriate connectivity capabilities for
integration with the future SCADA program and controls to communicate with these facilities. eHT has drafted a proposed
amendment to account for the design changes needed on this project, in the amount of$119,315.00, bringing their revised
contract amount to$694,125.00. Review of the proposal by Engineering and Projects staff has determined that the proposal is
complete and reasonable and will provide the effort needed to complete this project through design, bid, construction and post
construction phases. No additional funds are requested for bid or construction phases in this proposal

Re: Bailey Water Plant Improvements & Bailey Sewer Line (Veterans to Bailey WTP)
Purpose
This memo provides information about the progress on the Bailey Water Plant Improvements& Bailey Sewer
Line (Veterans to Bailey WTP) projects' status and the forthcoming proposed design contract amendment
for Enprotec / Hibbs & Todd (eHT). This amendment is scheduled for presentation to Council on the
September 27, 2021 meeting agenda.
Background
Both the Bailey water well and the Magnolia water well have elevated levels of manganese and iron that
cause taste, odor, and appearance issues. These items are secondary contaminants that fall under the
secondary regulations list that do not affect the safety of the water and so are considered nuisance
constituents due to the color, taste, and odor they impart. This project will address these secondary
contaminants at both plants by installing an additional treatment process for the plants. Both water wells are
necessary per our Water Master Plan and Water Model to meet regulatory capacities as the City builds-out.
The project is part of our overall water quality improvement efforts and will significantly reduce or eliminate
the water quality issues allowing the plants to return to service.
Council awarded a design contract to eHT in January 2019. Phase 1 of this project installed a new 1 MG
prestressed concrete Ground Storage Tank (GST) to replace the existing welded steel tank. Construction of
Phase 1 was awarded to DN Tanks in July 2019, and the Phase 1 was completed in June 2020.
The design consultant provided a draft Basis of Design Report for the treatment process while Phase 1
construction was in progress. That report recommended a common treatment system for both plants located
at the Bailey plant prompting the addition of a transmission line from the Magnolia as well as a sanitary sewer
line that would carry the wastewater generated by the selected treatment process.
As the design progressed, an analysis of the planned gravity sanitary sewer line versus a lift station and force
main was performed due to the required depth of the gravity line being over 29' deep due to the starting depth
to clear the ditch next to the water plant. Open cutting a line of this depth will have significant impacts on the
Recreation Center & Natatorium (RCN), requiring removal/replacement of the landscaping, signage,
driveways, and a portion of the parking lot. Alternatively, to install a gravity line at this depth with trenchless
methods is extremely expensive. The analysis showed a local lift station that will serve the water plant, future
Fire Station #7, and the surrounding area owned by Pearland Independent School District (PISD) will
eliminate those disruptions and reduce project costs by approximately $1.0M.
Phase 2 now includes: A treatment system (Aerelater) to remove the iron and manganese, installation of a
waterline to transport water from the Magnolia Water Plant to the Bailey Treatment Plant, installation of a
new local Lift Station and Force Main to discharge backwash from the treatment system to the gravity sanitary
sewer line at Veterans and Bailey, SCADA integration, and removal of the existing steel GST.
pcoming Contract Amendment
Two prior amendments for eHT added the water transmission line from the Magnolia plant to the Bailey
plant, and the gravity sanitary sewer line.
The current amendment is for the design of the Lift Station and Force Main to replace the gravity line,
electrical and pumping upgrades at the Magnolia site determined to be necessary to send the water to the
Bailey plant, and additional SCADA programming and controls to communicate with these combined facilities.
eHT has drafted a proposed amendment to account for the design changes needed in the amount of
$119,315.00. Review of the proposal by Engineering and Projects Staff has determined that the proposal is
complete and reasonable and will provide the effort needed to complete this project through design, bid,
construction, and post construction phases. No additional funds are requested for bid or construction phases
in this proposal.
Current Status
The 90% submission was received in March 2021 and reviewed with staff from Engineering and Public Works
in April 2021. Coordination with CenterPoint Energy is ongoing to provide natural gas for the new generator.
BNSF has reviewed and approved the waterline crossing perpendicular to their existing infrastructure and
an agreement to allow the installation has been executed for this work. This agreement provides the City's
contractor with the pipeline license needed to work in the Railroad easement.
Next Steps
There is approximately one month remaining to finalizing the design for review by the Technical Review
Committee (TRC) prior to issuing a bid-level plan set with the bid advertisement. Upon approval of the
amendment, eHT will implement these final details and submit the 100% plans, specifications, and
construction estimate. Advertisement for proposals is scheduled for November, with a mandatory pre-bid
conference and site visit following. The project will utilize the Competitive Sealed Proposal (Local Gov't Code
Chapter 2269), subchapter (B) procurement process.
Once the project has been bid and awarded the construction is expected to begin in January 2022. The
construction phase is anticipated at 18 (eighteen) months to substantial completion.
