APPROVED BY: Brian C. Wright, General Manager RECOMMENDATION: Adopt Resolution 2024-19 accepting the Joe Aguera Pump Station project as complete and authorizing the filing of the Notice of Completion. BACKGROUND: The Tahoe Donner subdivision consists of approximately 5,600 single-family homes, about 400 multifamily residential units, a golf course, a downhill ski area, a cross- country ski area and other amenities. This represents about 44% of the water system customers. An additional 500 residential units are expected in the Tahoe Donner area in build-out conditions. A single 14" welded steel pipeline serves the entire subdivision with two pump stations and two storage tanks that essentially serve as forebays. These facilities were constructed in the early 1970s and are approaching the end of their useful life. The District previously identified the need to construct a second pipeline into Tahoe Donner, and this project was discussed in the current Water System Master Plan. The master plan identified the need for a 20" pipeline, but more recent estimates of buildout water demand have determined the pipeline could be downsized to 16" diameter. On the eastern end, this new pipeline connects to a 24" pipe near Pioneer Trail and Comstock Drive. The western end connects to a 16" pipe at the intersection of Northwoods Boulevard and Lamplighter Way. Electrical and communications conduits were installed in a joint trench with the water pipeline. A new pump station is needed to lift water into the Tahoe Donner area through the new pipeline. The pump station is located on District-owned property in close proximity to the TNT Materials concrete batch plant. Page 1 of 4 Page 25 of 72 The overall project was broken into two separate construction contracts — one covering the pump station and the other covering the pipeline and conduits. In June 2022, the District awarded the pipeline construction contract to C&D Contractors. The District accepted the pipeline project in November 2023. ANALYSIS AND BODY: In August 2022, the Board awarded the pump station construction contract to M-3 Construction. The bid price for M-3 Construction was $2,516,250. The Board also established a ten percent change order allowance of $251,625 for a total authorization not to exceed $2,767,875. The pump station has completed functional testing, and the project should be accepted by the District. Attached is a draft resolution (Attachment 1) accepting the project and directing that a Notice of Completion be filed. There were twelve change order requests during the project. Some of these items are related, and they can be grouped into seven general items: 1. The original project design minimized the tree removal at the site. However, after the damage that occurred to the Red Mountain Tank from a large tree toppled in a storm, it was decided to remove a number of additional trees to minimize the potential for similar damage. Some additional hydroseeding was also associated with this effort. The cost for this work was $33,414. 2. The original project design called for an exterior light standard adjacent to the driveway. District field crews expressed concerns about this light standard interfering with snow removal operations. It was decided to delete the light standard and install an exterior wall mounted light near the generator instead. This resulted in a credit of$3,513 to the District. 3. The specification section governing instrumentation was inadvertently left out of the bidding documents. This oversight was not discovered until after the construction contract was awarded. Once the specification section was reviewed by M-3, some changes to the instrumentation were required. The cost for this work was $17,600. 4. There were some minor changes to the project, including relocation of the generator load bank for improved snow removal operations, installation of two bollards removal or two additional tree stumps, changes to the building signage and increasing the size of the concrete pump pedestals. The cost for this work was $12,583. 5. The original contract documents called for the installation of a 150 psi-rated air compressor. However, the actual discharge pressure of the pump station is about 210 psi, and an air compressor rated for 250 psi is required. This issue was discovered about midway through the project, after the 150 psi compressor had already been purchased. The cost for the new compressor, along with replacing some pressure sensors and related instrumentation, totaled $46,413. Page 2 of 4 Page 26 of 72 6. Obtaining the replacement air compressor noted above delayed completion of the project by about four months. This also required the contractor-purchased insurance coverages to be extended, at a cost of$17,741 . 7. The majority of the bid schedule included lump sum/fixed price items. Payment for asphalt paving work and rock excavation was based upon a unit price bid. The original bid included 3,300 square feet of new paving. The actual amount of paving was 4,500 square feet, for an additional cost of $18,000. The original bid included 10 hours of rock excavation. Only six hours were necessary to complete the project. This results in a credit of $4,000 to the District. GOALS AND OBJECTIVES: District Code 1 .05.020 Objectives: 1. Responsibly serve the public. 3. Provide reliable and high quality water supply and distribution system to meet current and future needs. 5. Manage the District in an environmentally sound manner. 6.

The Board also established a ten percent change order allowance of$251,625 for a total authorization not to exceed $2,767,875. Once adjustments are made for the items described above, the final contract price is $2,654,488. Item Amount Original bid price $2,516,250 Tree removal & $33,414 hydroseeding ($3,513) Delete exterior light $17,600 standard $12,583 Instrumentation specification provisions Minor project changes 250 psi rated air $46,413 compressor Page 3 of 4 Page 27 of 72 Extension of insurance $17,741 coverages Reconciliation of bid vs. $14,000 actual quantities Total $2,654,488 The funding source for this project is the water utility's 2022 debt issuance project funds. In addition to the amount paid to M-3 Construction, the District has incurred additional outside expenses for construction inspection and geotechnical testing.
