CITY: CITI 0 E CONTRACTOR: 7—VTFA 7 h.l L By: Print Name: klg6 Title: Vjy rs /ISG 1T EXHIBIT "A" PROPOSAL July 17, 2018 Mr. Chris Sorensen City of Beaumont 550 E. 6th Street Beaumont, CA 92223 Reference: Seneca Springs Lift Station Dear Mr. Sorensen: Understanding and Approach The City is experiencing what appears to be settlement problems with the Seneca Springs Sewer Lift Station. Settlement appears to be a few inches and this is creating problems with piping. The City would like to identify the cause of the problem, identify a recommendation for repair, and then obtain construction bids to implement the repair. From our preliminary desktop evaluation, it appears that the concrete slab is settling but the wet well and large diameter piping are not. We imagine that the wet well construction included removal and replacement of the adjacent soils and that the replacement soil was not correctly compacted. The Contractor may have not adequately compacted the entire 33' of soil. We will conduct a site visit and look more thoroughly through the data and interview City staff to confirm the above. We have assumed the above as the basis for this proposal. We expect to evaluate two alternatives. The first alternative would be a traditional removal of the concrete slab, overex and recompact the soils, and reconstruct the slab. If the lift station cannot be completely taken out of service, the slab could be cut and the process completed in two phases. There are a couple of considerations for this method. One is that if compaction is poor deeper down, it may not be practical to overex very deep. In that case, the slab would be prone to settle after reconstruction. One fix would be to add structural strength that attaches the slab to the wet well and cantilevers off of the wet well. That fix would make the slab less dependent on the underlying soils. The second alternative, which would require further investigation, would be to pressure grout under the slab and lift it back into place. Due to the size of the slab, controls would need to be identified in order to ensure that the raising of the slab can be controlled so that the entire slab is raised in unison. Project Team and Experience Our team specializes in engineering for public wastewater/water systems. Experience includes planning, engineering, and construction assistance for distribution conveyance/system components including lift 160 E.

We would be happy to expand on our team members experience at the request of the City. PROJECT TEAM CHARY Awa T TETRA TECH PR0IECT MANAGER Ken Berard, PE Scope 1. Project Management. Manage and coordinate project including budget, schedule, subconsultants, invoicing, etc. 2. Geotechnical Report - Using the RFP and as -built plans, our subconsultant, Leighton Consulting, proposes forensic geotechnical subsurface exploration to support a geotechnical/structural design -fix intended to stabilize this lift station. The proposed work will include drilling borings at this lift station site, performing geotechnical laboratory testing and prepare a Geotechnical -Distress Subsurface Exploration report to design a fix for this lift station. The geotechnical -distress exploration scope is described in more detail as follows: Mobilization Preparation and Coordination: Leighton Consulting, Inc. will mark out proposed borings locations, coordinate access with City of Beaumont staff and notify Underground Service Alert (USA) at least 48 -hours prior to drilling, to locate and avoid known underground utilities and easements. We will also review our in-house reports for this area and any relevant published geologic reports/maps (USGS, CGS, Riverside County, etc.). We will also request that the City provide all available geotechnical reports for this site, for our review. • Private Utility Locator: As noted above, we will contact Underground Service Alert (USA) prior to beginning fieldwork so that registered public utilities in the area of our proposed borings will be marked. However, due to the close proximity of existing buried sewer and other pipes (and other substructures), we will also subcontract a private utility locator to help reduce risk of damaging underground utilities during subsurface exploration. Our primary goal is to "do no harm." • Exploratory Borings: Leighton will drill, log and sample two large -diameter borings within accessible asphalt pavement (not concrete) areas of this lift station site. Our borings will be drilled to a maximum 50 feet below existing ground surface or practical auger refusal on dense/coarse alluvium. Leighton Consulting, Inc.'s field staff will log borings from the surface and downhole (if the subsurface conditions TETRA TECH allow downhole logging safely). Driven "California" ring -lined samples and bulk soil samples will be collected. Soil samples will be transported to our in-house geotechnical laboratory for testing. Borings will be backfilled with excavated soil cuttings from drilling and pavement will be patched at the surface with quick -setting concrete, if needed. • Geotechnical Laboratory Testing: Geotechnical laboratory tests will be performed on selected, representative soil samples to determine pertinent engineering properties. Tests may include in-situ moisture/density, sieve analysis, modified Proctor compaction curves and consolidation tests. As an option (Option 1), site soils can be tested with a soil corrosivity suite (sulfate content, chloride, pH, and resistivity). • Geotechnical Analyses and Report: Geotechnical data analyses will consist of review of existing in-house data and analyses of collected subsurface and geotechnical laboratory data by our California licensed Geotechnical Engineer (GE). Leighton Consulting, Inc. will prepare a report summarizing field and laboratory findings and conclusions of this exploration and provide geotechnical recommendations. This report will be signed and stamped by a GE. 3. Site Visit & Kick-off Meeting. Visit the site and attend kick-off meeting with the City either at the City offices or at the site. 4. Technical Memo. Evaluate traditional remove and replace vs. pressure grout repair. Provide technical memo summarizing the evaluation and recommendation. Technical memo is anticipated to be 2 to 3 pages long. Submit draft, make revisions if needed after City review, and finalize. 5. Construction Documents. Traditional remove and replace is assumed. Pressure grouting option may be less. Includes structural calculations. Piping is assumed to be removed and then replace with existing piping. Anticipate structural design of slab to include cantilever support from the wet well. 6. Cost Estimates & Submittals. A complete draft of the construction documents and -cost estimates will be - made. After City comments, the documents will be revised and the final bid set will be submitted. Schedule We will complete a draft technical memo with recommendations in about 2 weeks from the site visit/kick- off meeting. Draft construction documents will take about 4 weeks from acceptance of the technical memo and the final construction documents will take 1 to 2 weeks from receipt of City comment on the draft. Budget We propose a time and materials budget with a not -to -exceed fee of $44,000. We anticipate that if a pressure grout repair method is utilized, we may not reach the fee cap. Please contact me any time to discuss this proposal at (909) 305-2939. Sincerely, X7�t� AAt_v� Ken Berard, P.E.

Suburban Water Systems, Plant 224 Facility Improvements, Whittier, CA. 2014. Design Engineer for the design and construction assistance for the plant improvements. A conceptual plan was developed to construct a 13,000 gpm pump station and as much potable water storage as practical at Suburban Water System's 224 Plant. The concept required close coordination with the City of Whittier in order to obtain DRA, CUP, and Building Department permits. A detailed report was developed and presented to the Public Utility Commission in order to justify the project and obtain funding. Two conventionally reinforced partially buried reservoirs store 2.4 MG and 4.7 MG of potable water. In order to meet the City of Whittier's development requirements, an Art Deco architectural style was adopted which included a 30 -foot high fagade in the front of the site and architectural pilasters and cornices on the exposed reservoir and pump station walls. The fagade includes a 5.5 -foot diameter clock and bronzed letters identifying the owner. The architectural theme is compatible with a historical pump station building at an adjacent site. The site work includes a bioswale and retention basin to handle storm water flows. A.C. pavement is limited and gravel/landscaping maximized in order to minimize storm water run-off, maximize aquifer recharge, and enhance the storm water quality run-off. Construction was phased into three parts to match available funding. The first phase included much of the site earthwork and perimeter fencing and Tetra Tech provided the final design, special inspection, and construction assistance. The second phase included piping and the pump station. Tetra Tech provided HVAC, structural, and architectural design while Suburban led the phase and provided the remaining design. Tetra Tech also provided special inspection and construction support services. The third phase included both reservoirs, the architectural fagade, and final site work. Tetra Tech led this effort while Suburban provided electrical and controls design. Tetra Tech also provided comprehensive construction management services.

The report evaluated various concrete and steel tank options as well as a geotechnical evaluation to stabilize a 2:1 slope and were used to obtain approval from the PUC. The project design and construction was divided into 4 phases. Tetra Tech and Suburban Engineering collaborated to provide a jointly engineered project. Demolition involved wastes such as AC pipe, lead paint, oil impregnated soils, and asbestos. Rough grading of the site required about 60,000 CY of earthwork and construction of over 1000' of retaining walls. The walls surrounding the site retained from 10' to 18' with slopes used to reduce wall heights. The majority of wall utilized piles and tie -back construction while smaller portions utilized pile walls without tie- backs, concrete walls, and CMU construction. Water improvements included two 2.4 MG steel tanks, a 1.9 MG steel tank, and a 3,000 gpm pump station. Adrian, Page 2 THOMAS C.

BENSON, JR. PE, GE PROJECT EXPERIENCE (Continued) Suburban Water Systems' Plant 224 Pump Station, Whittier: As subconsultant to Tetra Tech, in 2012, Mr. Benson was hands-on Principal reviewer of a geotechnical exploration for the design and construction of Suburban Water Systems' Plant 224 Pump Station and Potable Water Reservoir located in southeastern Whittier, California. Rough grading for this pump station is underway in March 2013, as an old reservoir on this site is being demolished and filled in to grade a pad for this new pump station, and eventually a new reservoir at this redeveloped waterworks site located on the north side of Whittier Boulevard. Cost- effective geotechnical recommendations were developed to reduce differential settlement of this proposed pump station, partially overlying a filled in demolished reservoir area and partially over undisturbed native soils. City of Riverside Expanded Gage Pump Station: In 2012, Mr. Benson was hands-on Principal reviewer of a geotechnical exploration for the design and construction of a new booster pump station consisting of a 30 by 40 foot reinforced concrete vault and wet well extending 20 -feet below existing grade. This site is located southeast of the SR -91, SR -60 and 1-215 interchange. Differential settlement of an above -grade electrical room relative to the abutting below grade wet well was considered and mitigated. Leighton's geotechnical exploration report was completed on time and for the originally proposed fixed fee with no uncertainties; on budget. CVWD WRP No. 10 Effluent Pump Station, Palm Desert: As subconsultant to Tetra Tech, in 2012, Mr. Benson was hands-on Principal reviewer of a successfully completed geotechnical exploration for design and construction of Coachella Valley Water District's (CVWD's) Water Reclamation Plant (WRP) No. 10, proposed secondary effluent pump station; to be constructed within the southern portion of this plant. This pump station will be a below -ground cast -in-place concrete clear well with vertical turbine pumps and mechanical piping located above ground on a structural slab -on -grade. This area of Palm Desert is known to have active alluvial valley subsidence, as well as generally very deep groundwater; although this site was adjacent to an existing sewage lagoon. This site is located within an active sewage lagoon field, adjacent to and within lagoon embankments; requiring remedial earthwork for uniform shallow foundation support. CVWD SR -86 Pump Station, Riverside County: In 2012, Mr. Benson was hands- on Principal reviewer of a successfully completed a geotechnical exploration for the design and construction of a booster pump station in the Oasis area of unincorporated Riverside County, near the northwest shore of the Salton Sea. This proposed pump station site is located below sea level, and is within an area of known active alluvial valley subsidence. Lacustrine soils consisting of sands and silts were encountered. To mitigate potential for variable undocumented fill soils within the building pad footprint, liquefaction -induced settlement and regional ground subsidence, we recommended cost-effective remedial earthwork to support shallow foundations. Recommendations for mitigating corrosive soils were also provided for this lacustrine site near the Salton Sea. Page 2 of 2 4C Leighton Consulting, Inc. .. IS1.4I ON 1­1CUY��N1
