RE: Amendment # 1 for Wastewater Treatment Plant # 3 Septage Processing Unit in Bakersfield, California
Ir•IX_ 111
Provost and Pritchard Consulting Group ( P&P) is requesting The City of Bakersfield increase the allocated contract amount beyond what has already been contracted for the Wastewater Treatment Plant # 3 Septage Processing Unit Replacement Project ( Project) to cover additional scope of work not included in the original contract documents.
The original agreement for this project dated February 2, 2022, included a budget for design, bidding, and construction assistance. The design budget for the contract has been exceeded due in part to working with the City of Bakersfield and Huber on various items that were not within the scope of the original agreement including requests for P&P to review Huber design submittals. These items are detailed below.
Phase 01: Preliminary Design (Additional Scope of Work) Additional items not included in the original scope of work are detailed below.
Assumption three in the original contract documents detailed that P&P assumed the existing electrical circuit for the SPU would have capacity for the new SPU unit. The existing power and networking conduits are full and are not code compliant ( per NEC Chapter 9 Table 1).
Design provisions were made to include a new power feeder and network feeder to the SPU. Total additional compensation requested is $ 1, 500.
Design provisions to include a new housekeeping pad, shade structure, and removable bollards for the SPU power and controls equipment not originally known at the proposal stage for the project. Total additional compensation requested is $ 2,000.
The existing SPU controls enclosure combines higher voltage power with low voltage signal and control cabling. This is not a recommended practice and can cause induced voltage and current in the cables, and compromise signal and control functions. In talking with Huber and the City, P&P designed a new power distribution feeder, power distribution panel, and network feed. These design elements allow for the isolation of power and controls cabling, and isolation of each SPU unit. Total additional compensation requested is $ 1, 500.
There have been unresolved design elements related to the booster pump as well as the SPU control/ power/ instrumentation/ distribution systems that will need to be incorporated into the plans between now and the final submittal; P& P has continued to have an open dialogue G:Oakersfield_ City of- 1046\ 104623002- WWrP3 Septage Processing Unit Upgrade\ 000 Project Management\ 010 Contract - Amendments\ Amendment 1\231110- Revised amendment\ 2023- 1127 - Amendment t. docx

with the City and Huber on these items, and efforts have been in excess of what would reasonably be expected. These items have been discussed over a number of additional meetings and emails between the City of Bakersfield, Huber and P&P. Total additional compensation requested is $ 2, 500.
P&P received a design submittal from Huber via the City of Bakersfield on 9/ 13/23, and we have attempted to integrate the relevant portions of that submittal into the in -progress P& P plans and specifications at the same time as corrections were being made in response to comments received by the City. However, once received, it was observed by P&P that various items were not correct or missing in the Huber plans. This necessitated a more detailed review, which P& P did at the time in an effort to keep the project moving along although reviewing Huber design submittals are not an item covered by our scope of services under this contract. Final comments were provided to the City and Huber on 9/ 20/ 23. The total requested additional budget amount based on actual labor expended during that time is $ 1, 700. 00.
A second submittal was received from Huber via the City on 10/20/23, and a brief preliminary review was performed during the week of 10/23/23. It was noted that the total size of the submittal was approximately twice the size of the previous submittal, and several items were noted which would likely require a detailed look at the submittal. The City requested this additional scope amendment at this time before our proceeding with the review. The total requested additional budget amount based on actual labor expended is $ 1, 500. 00.
It is understood that the submittal we provided preliminary comments on has been nullified by Huber and that a follow up resubmittal is pending. P&P anticipates that it will be necessary to review said submittal when it is transmitted. As discussed, it is believed to be imperative to review this submittal thoroughly in order to coordinate the manufacturer submittal and the P&P plans and specifications as much as possible in an effort to protect the City from any change order claims by the contractor during construction. The total requested additional budget for this effort is $ 5, 000. 00. a. Deliverable — Detailed markups of Huber submittal.
b. Schedule — Allow up to three ( 3) weeks for review and transmittal of deliverable.
After P& P provides the deliverable outlined above, it is believed to be best to schedule a coordination call with the City and Huber to discuss the markups and to clarify any final remaining items which might be necessary ahead of Huber finalizing their design package for one final ( third) submittal to the City and P&P. The total requested additional budget for this effort is $ 1, 000. 00.
a. Schedule — Allow one ( 1) week from the deliverable indicated above to schedule this meeting, depending on schedules of participants.
It is expected that the resubmittal from Huber will be substantially complete and no additional rounds of response from P&P will be necessary. Additional submittal reviews may result in an additional amendment to cover costs of review. At this point, P&P will review the submittal and make final modifications to its plans and specifications in coordination with the Huber submittal. This will result in a set of plans and specifications that are ready to be issued for bid. The total requested additional budget for this effort is $ 2, 000. 00. a. Deliverable — Final plans and specifications to be issued for bid. b. Schedule — Allow up to three ( 3) weeks for the deliverable. t— m
