Subject: Approval of Plans, Specifications and Contract Documents and Authorization to Advertise for Bids for the Poinsettia Lift Station Generator Replacement Project
District: 2
Rec
ommended Action
Adopt a resolution approving the plans, specifications and contract documents and authorizing the City Clerk to advertise for bids for the Poinsettia Lift Station Generator Replacement Project.

Executive Summary
The backup generator at the Poinsettia Lift Station is at the end of its service life and requires replacement to ensure the station’s operability in the event of a power outage. A reliable supply of electricity is needed at the lift station to pump wastewater flows uphill and to the wastewater treatment plant. Power outages without generator backup could result in wastewater spills. The total construction cost estimate including contingency, construction management and staff costs is $905,000.

City Council approval of these plans, specifications and contract documents is required under Carlsbad Municipal Code Section 3.28.080(E) because the expected value of work is more than $200,000.

Staff recommend that the City Council approve the project plans, specifications and contract documents and authorize the City Clerk to advertise and receive construction bids.

Explanation & Analysis
The city operates 12 sewer lift stations that pump wastewater flow uphill and to higher elevations and are equipped with emergency generators to provide a backup power source to the pumping system during power outages.

Item #2 Page 1 of 7

The emergency backup generator at the Poinsettia Lift Station was installed in 1999 and is the second largest generator of the lift station sites operated by the city. The generator is at the end of its service life and needs replacement. The scope of the project includes:
• Replacement of the existing 250-kilowatt diesel-fueled generator • Associated power system controls and communication upgrades • Upgrades to the generator housing structure to achieve compliance with current building and fire codes
Staff recommend that the City Council approve the plans, specifications and contract documents and authorize the City Clerk to advertise for construction bids for the project.

Fiscal An
alysis
The project is a component of the Sewer Lift Station Repairs and Upgrades Program, Capital Improvement Program Project No. 3840, which is funded by the city’s sewer replacement fund.

Sufficient funds are available to complete the project. Available funds and estimated construction costs to complete the project are presented in the table below:

Sewer Lift Station Repairs and Upgrade Program
Capital Improvement Program Project No. 3840
Total appropriation to date $4,535,380
Total expenditures/encumbrances to date -$3,143,659
Total available balance $1,391,721
Poinsettia Lift Station Generator Replacement

Construction management, inspection and testing (estimated) -$120,000 Staff time and engineering construction services -$50,000 Total estimated construction costs -$905,000
Remaining balance $486,721

Next Steps
With the City Council’s approval, the City Clerk will advertise a request for bids for the project.

Staff will then evaluate the bids received and identify the lowest responsive and responsible bidder. Staff will then return to the City Council with a recommendation to award a construction contract to the identified lowest responsible and responsive bidder, which is expected to be in spring 2024.

4-1.9 Construction Materials Dis pute Resolution (Soils, Rock Materials, Concre te, Mortar and Related Materials, Masonry Materials, Bituminous Materials, Rock Products , and Modified Asphalts). In the interest of safety and public value, whenever credible evidence arises to c ontradict the test values of materials, the Agency and the C ontractor will initiate an immediate and cooperative investigation. Test values of materials are resul ts of the materials’ tests, as def ined by the se Sp ecifications or by the spe cial pr ovisions, r equired to acc ept t he Work. C redible evidence is process obs ervations o r test v alues gathered u sing ind ustry accepted practices. A contradiction exi sts whenever test values or process observations of the same or similar materials are diverse enough such that the work ac ceptance or per formance becomes suspect. The i nvestigation shall allow access to all test results, procedures, and facilities relevant to the disput ed work and consider all av ailable information and , when necessary, g ather new and additional information in an a ttempt to determine the validity, the cause, a nd if necessary, the remedy to the con tradiction. If the c ooperative investigation reaches any re solution mechanism ac ceptable to b oth the Age ncy a nd the Contr actor, the contradiction s hall b e considered r esolved and the cooperative investigation conc luded.

Whenever the cooperative investigation is unable to reach resolution, the investigation may then either conclude wit hout resolution or conti nue by written notification of one party to the other requesting the implementation of a resolution process b y com mittee. The co ntinuance of the investigation shall be contingent upon recipient’s agreement and acknowledged in writing within 3 ca lendar days after receiving a request. Wit hout ac knowledgement, the invest igation shall conclude without resolution. The committee shall consist of three State of California Registered Civil Engineers. Within 7 calendar days after the written request notification, the Agency and the Contractor wil l each select one engineer. With in 14 calendar days of the written request notification, the two selected engineers will select a third engineer. The goal in selectio n of the third member is to complem ent the professional experience of the fi rst two engineers. Should the two engineers fa il to select th e third engineer, the Agency an d the Contractor shall each propose 2 engineers to be the third member within 21 calendar days after t he written request notification. T he first tw o eng ineers previ ously s elected shall then select one of the fo ur proposed engineers in a blind draw. The com mittee shall be a c ontinuance of th e cooperative investigation and will re -consider all available info rmation and if necessary, gather n ew and additional information to determine the validity, the cause, and if necessary, the remedy to the contradiction. The committee will focus upon the performance adequacy of the material(s) using

Revised 6/15/17 Contract No. 3840-23 Page 80 of 134
standard engineering pr inciples and practice s and to ensure public v alue, the committee may provide engineering recommendations as necessary. Unless otherwise agreed, the commit tee will have 30 calendar days from its formation to complete their review and submit their findings.

The final resolution of the committee shall b e by majority opi nion, i n writi ng, sta mped and signed. Should t he final resolu tion not be unanimous, the diss enter may a ttach a written, stamped, and signed minority opinion. Once started, the resolution process by committee shall continue to full conclusion unless:

1. Within 7 days of the formation of the committee, the Agency and the Contractor reach an acceptable resolution mechanism; or

2. Within 14 days of the formation of the committee, the initiating party withdraws its written notification and agrees to bear all investigative related costs thus far incurred; or

3. At any point by the mutu al agreement of the Agency and the C ontractor. Unless otherwise agreed , the Con tractor sh all bear and maintain a reco rd for all the investigative costs until resolution. Should t he investigation discover assignable causes for the contradiction, the assignable party, the Agency or the Contrac tor, shall bear all costs associated with t he investigation. Should assignable causes for the contradi ction extended to both parties, the investigation will assign costs cooperatively with each party or when necessary, equally. Should the investigation substantiate a contradiction without assignable cause, t he investigation will assign costs cooperatively with each pa rty or when necessary, equal ly. Should th e i nvestigation be unable to su bstantiate a contradiction, the initiator of the investigation shall bear all investigative costs. All c laim notification r equirements of the contract pertaining to the con tradiction s hall be suspended until the investigation is concluded.
