As such, City Administration has determined the purchase of two lots; located at 2405 and 2413 Seward Highway, are the most suitable location to construct a new Public Works Facility. City Council passed resolution 2022-005, which directed the City Manager to begin the process of investigating the viability of these lots for the purpose of constructing a new Public Works Facility. This task order will provide the necessary geotechnical information in order to assess the viability of this site.

RE: Geotechnical Investigation Proposal for New Public Works Vehicle Maintenance Facility FaiTba-nks, 99701 Dear Mr. Sowell: 907.452.5270 R&M Consultants, Inc. (R&M) is pleased to submit this proposal to provide geotechnical services 90 in support of your new Public Works Vehicle Maintenance Facility. This is a proposed new task under our existing On-Call Engineering Services term contract with the City of Seward. We understand the City of Seward plans to construct a new 12,000 square-foot maintenance shop building.The new site is to be located on two combined properties at 2405&2413 Seward Highway in Seward, opposite the highway from the runway of the Seward Airport.The purpose of our work will be to explore the subsurface conditions at the site to inform the design and construction of the new facilities.All reports, plans, and recommendations will be prepared under the supervision of a professional engineer registered in the State of Alaska. SCOPE OF GEOTECHNICAL SERVICES Site Investigation At this pre-design stage of the project, the exact layout of the proposed building and associated facilities has not yet been defined. For the site investigation,we have assumed that the preliminary building location will be determined, which will allow the investigation to target the building footprint. For planning purposes, we propose a subsurface investigation consisting of drilling 6 boreholes total: including two down to depths of 70 feet and the remaining four down to depths of 30 feet. We anticipate locating 3 or 4 of the boreholes within the building footprint, while the remaining will be within parking/driveway areas or ancillary features. Proposed borehole locations will be selected prior to the site investigation and submitted to the City of Seward for approval. Prior to mobilization for drilling, R&M will obtain public utility locates for the above referenced project location. We have assumed that the City of Seward will be responsible for providing right- of-entry and work access to the project site. The boreholes will be drilled with nominal 8-inch diameter hollow-stem-augers and/or rotary wash methods. R&M intends to complete the subsurface investigation using either a truck-mounted CME-75 or track-mounted Geoprobe 7822DT drill rig, provided and operated by Discovery Drilling, Inc. of Anchorage, Alaska. Disturbed yet representative soil samples will be collected using split- barrel drive sampling equipment, taken at 2.5-feet, 5-feet, and on a 5-foot interval to 50 feet and on a 10-foot interval thereafter to completion depth. Sampling procedures will generally follow either Standard Penetration Test(SPT)(per ASTM D 1586)or Large Penetration Test(LPT)methods. Soil samples will be classified in the field using the Standard Practice for Description and Identification of Soils(Visual-Manual Procedure)(ASTM D 2488). Mr. Stephen Sowell January 20, 2022 Page 2 of 2 We plan to install PVC standpipes at two select borehole locations to record stabilized groundwater levels, while onsite. All boreholes will be backfilled with drill cuttings, and flush-mount covers will be installed at the two standpipes. Laboratory Testing All retained geotechnical soil samples will be returned to R&M's laboratory for classification (following ASTM D 2487 and 2488).The moisture content, particle-size distribution, and percent passing No. 200 sieve (P200 wash) of several samples will be tested to support our interpretation of the relevant soil index properties for each lithological unit encountered. Reporting R&M will prepare a geotechnical report that includes a summary of the exploration methods; description of laboratory testing; our interpretation of the subsurface conditions (soils, groundwater, etc.) at the site; results of geotechnical analyses, and corresponding geotechnical recommendations. Records of test boring logs, results of lab testing, sample and site photos,and vicinity and test boring location maps will be attached with the report.The report will present seismic design ground motions from USGS, including our interpretation of seismic site soil class, and consider the potential for liquefaction and seismically-induced ground deformations at the site. Geotechnical recommendations will be provided for site preparation, earthworks and fill materials where needed, subgrade recommendations for asphalt or concrete pavement and slabs, and assumed suitability of shallow concrete foundations supporting the building. PRICE R&M will provide the above services on a Time and Expenses basis with a not-to-exceed price of$71,591 as detailed on the attached spreadsheet. In this estimate, we have planned for four days of drilling, and will not exceed that without prior authorization. ASSUMPTIONS AND CONDITIONS R&M's proposal and fee are based on acknowledgement that: • The City of Seward will be responsible for providing right-of entry and work access to the project site. • The City of Seward understands the test boring will be advanced and sampled following procedures applicable to geotechnical investigations.These procedures are not appropriate for sampling or evaluating contaminated soils. If contaminated soils or groundwater are suspected or encountered in the geotechnical test boring, R&M will note the issue on our field log but will not collect environmental samples.
