Project Update

EPA LOI HIGHLIGHTS

2

• Regional/National Significance:
• The City of Wichita is the largest provider of

regional drinking water in the state of Kansas, providing drinking water to more than 500,000 people.

• Aging Infrastructure and Utility Risk:
• The single MWTP and the overall poor

condition of the MWTP constitute an unacceptable level of risk to the City of Wichita and the region.

• Project Timing and Risk Mitigation:
• The NWWTF project would be delayed a

minimum of 7 years in the absence of WIFIA financing.

• Asset Management and Utility Optimization:
• The City’s proactive asset management

program will extend the expected life of project assets.

• Adaptive Resource Management:
• The adaptive management practices focus on

maintaining the viability of all sources during extended drought periods.

BACKGROUND

• Council approved release of NWWTF RFP on

July 10th

• Two-phase process to construct a new water

treatment plant using a DBo model

• Nearly 80 years old
• Existing treatment plant is at risk of failure;

needs replaced to avoid catastrophic outages

• Greater delays in project create greater risk

to providing water service to approx. 500,000 people

PROCESS & SCHEDULE

• WIFIA timeline identified by EPA and drives project schedule
• Need to have 30% design, GMP, O&M Plan, Environmental Assessment and
• ther information to fulfill WIFIA application requirements
• Design process for application requirements expected to take 12 months*
• Delays jeopardize ability to complete the application process in time for WIFIA

SUMMARY OF PROPOSERS

5 D (Design) B (Build) O (Operate – short term) Jacobs Treatment: Non-Local Pipelines: Non-Local * Appx 70% Local Identified O&M Team Wichita Water Partners Treatment: Non-Local Pipelines: Local Significant Local Construction Planned No Identified O&M Team

* In contract discussions, Jacobs has indicated its preference to utilize local design firms for aspects of the pipelines

SUMMARY - DESIGN

6

Jacobs

• Treatment Plant Design, Modeling, and Asset

Management all by one firm out of Denver and Corvallis offices

• Pipeline and Supporting Assets Design by

Wood Engineering Wichita office. Jacobs working with other local firms on supporting designs

• Identified separation between design and

design QA/QC

• Risk management integrated in all design

decisions

• 3-D Modelling integrated & used in all of project

Wichita Water Partners

• Treatment Plant Design led by sub firm HDR
• ut of Omaha. Modeling and Asset

Management by HDR and B&M out of Kansas City

• Pipeline and Supporting Assets Design by sub

firms PEC, MKEC, GMLV, SJCF all of Wichita

• Overlap of individuals involved in design and

design QA/QC

• Discussed need for further risk allocation

discussions during design

• 3-D Modelling for Designer and Builder to

confirm constructability

Both teams would review previously identified design concepts

SUMMARY - BUILD

7

Jacobs

• Will issue competitive bid packages for at least

70-80% of project locally. Sub contractor McCarthy planning to hire locally as demonstrated on current project in Kansas

• Targeting a projected completion three months

early

• Identified potential areas of impact on

surrounding properties and mitigation measures to be utilized

• Identified labor needs and ability to work with

design to flatten the need rather than short term spikes in labor force Wichita Water Partners

• Alberici Construction part of joint venture with

sub contractors of three local firms with competitive bid packages to decide about 80%

• f construction responsibilities.
• Lack of discussion on construction

management and commissioning of facility

• Can meet overall schedule

SUMMARY - OPERATE

8

Jacobs

• Multiple project examples of short term
• perations and transition to City
• Extensive training plan developed and

demonstrated

• Training includes ‘flight’ simulator and other

tools that transition to City for training of new staff and refresher training

• Jacobs operates more than 200

United States water and wastewater facilities

• Competitive procurement part of this DBo RFP

process Wichita Water Partners

• One municipal utility and two private
• perations firms as subs during design and

construction narrowed to one prior to

• perations period
• Provided a general approach and methods to
• perations, training, and transition but with lack
• f detail
• Three sub-contract operators conduct
• perations for more than 200 water treatment

plants

• Competitive procurement would occur summer
• f 2019

SUMMARY - EXPERIENCE

9

Jacobs

• Proven DB and DBO and DBo experience
• Identified DBO projects of 30MGD, 100 MGD,

and 180MGD

• Identified at least nine water treatment plants

NWWTF size or larger

• Developed and/or reviewed 8 of the 12 WIFIA

Applications from 2017 Wichita Water Partners

• Proven DB experience
• No DBO projects identified
• Identified three water treatment plant projects

RISK-BASED GMP

13

• Design and construction cost a primary driver of rate increases
• Lowest possible GMP would minimize water rate adjustments
• “Risk and Opportunity Management Tool” tied to project scheduling would

be used to conduct probability analysis of costs and schedule changes

• Identifies risks with potential to add the highest costs
• Develops strategies to eliminate, minimize, and offset cost impacts

O&M PLAN

14

• WIFIA Application requirement for defined O&M Plan
• Experience with having O&M integrated into their organization
• Experience with O&M integrated into Design and Construction
• Defined O&M Transition Plan that includes staffing options
• O&M Plan that includes simulators and other tools for ongoing

training

CONCLUSION

15

Key Takeaways 1) City received two strong proposals 2) Delays to the schedule endangers WIFIA 3) Selection Committee unanimously recommends Jacobs

• Experience with O&M in organization
• More experience with similar projects
• Risk-based GMP should lower costs
• Advantages with construction sequencing

4) Represents the best team and schedule to minimize rate increases through a lower GMP and successful WIFIA application Recommended Future Actions
