It will also assist us in determining the necessary additional work needed for the design geotechnical report, if necessary. It is our understanding, the City of Bozeman is considering a 5.3 million -gallon (MG) water tank. Actual selection and sizing of the tank configuration is still in progress. The 5.3 MG tank would have an inside diameter of about 163 feet and an interior water depth of approximately 35 feet. To avoid pumping, consideration is being given to burying the tank 20 to 30 feet below the ground surface. We have assumed some water lines will be necessary to and from the tank. We have assumed we will be provided with a to -scale site plan showing the location of the proposed tanks and nearby fixed features prior to the fieldwork. We have also assumed the boring locations will be accessible to our truck -mounted drill rig, and no towing or snow removal services will be required. Access delays due to circumstances beyond our control could result in additional charges. We have also assumed our current insurance amounts are acceptable, and we can provide you with a certificate of insurance. Scope of Services Borehole Staking. We request you stake the boring locations at least three days prior to our drill crew's arrival on the site. We wHI assist in selecting the boring locations based on the selected tank size and location_ Lathe should be set at each boring location and Have pink and blue ribbon tied near the top. In pavement, the boring locations should be marked with spray paint and the lathe with ribbon offset. It would be beneficial to mark the lathe with the boring number, survey the location, and provide us with the ground surface elevations and GPS latitude -longitude coordinates. Our drill crew may have to alter the boring Iocations depending on access issues or utility conflicts. Soil Borings. We propose to provide five soil borings for the 53 MG tank: four around the perimeter, 90 degrees apart and one at the tank center. We propose to perform the tank center boring to a depth of 75 feet, and the remaining borings to 40 feet. Our firm has encountered auger refusal at depths ranging from about 17 to 25 feet in the dense gravels on the site. Therefore, the deeper boring will be performed with our casing advance system and mud rotary drilling technique to the termination depth. Because these borings require water, they are weather dependent. The air temperature needs to be 35 degrees Fahrenheit and rising. Therefore, there is a risk the borings may be delayed for several- months until warmer weather. Robert Peccia & Associates November 20, 2014 Proposal P -2166R1 Page 3 For the remaining borings, hollow -stem auger will be used with a larger drill rig (Diedrich D-120) and we will attempt to extend them to 40 feet, however, auger refusal could occur at shallower depths. We also propose to complete two of the 40 -foot borings as piezometers to allow contractors and others to measure groundwater levels in the tank area. We also propose to perform two soil borings to a depth of 20 feet along the water line to and from the tank(s). One of these borings will be completed as a piezometer. We propose to conduct penetration tests in the borings to assist in evaluating bearing capacities of the subsoils and to obtain representative samples for classification. The penetration tests will be conducted at 5 -foot intervals to the termination depths of the borings. A field engineer will be present while drilling to visually classify and log the samples from the borings. Some tube samples may be taken for laboratory strength and consolidation/swell testing. If groundwater is encountered, its depth will be recorded. Upon completion, the borings not completed as piezometers will be backfilled with auger cuttings to the ground surface. For the piezometers, we are proposing to install 1 -inch Schedule 40 PVC pipe. We will install 20 -foot screens in the 40 -foot piezometers, and a 10 -foot screen in the 20 -foot piezometer. Solid casing will then be provided above the screen to approximately 2 1/2 feet above the ground surface. Sand backfill will be provided to 2 feet above the screens, then a 2 -foot thick bentonite seal. Auger cuttings will then be used as backfill to within about 3 feet of the surface, where sackrete will be used and a stovepipe cover to protect the piezometer. A locking cap will be provided, however, no lock will be installed. Laboratory Testing. The samples will be returned to our laboratory and visually classified and logged by a geotechnical engineer. Some routine laboratory tests may be conducted to assist us in evaluating the strength and compressibility of the soils. Although the laboratory testing could vary, we are proposing the following. • 75 moisture content tests • Six classification (Atterberg limits and grain size) tests • Three consolidation/swell tests • Two moisture -density curves (Proctors) • Four corrosion tests, including pH, resistivity and sulfates Pre -Design Geotechnical Report. After the field and laboratory tests have been completed, the results will be analyzed and discussed with you and/or your structural engineer. A geotechnical engineering report will then be prepared. The report will address suitability of the soils to support the proposed shallow -spread footings and tank deck (slab), allowable bearing capacity for spread footings, improvements to footing and deck subgrades (if necessary), reuse of excavated material as backfill, and Robert Peccia & Associates November 20, 2014 Proposal P -2166R1 Page 4 recommendations for compaction. The report will also contain our recommendations regarding International Building Code (IBC) site class, seismic induced wall pressures, simplified liquefaction analysis, groundwater considerations, mapped spectral response accelerations S, and S1, and long period transition period TL. The geotechnical report will be prepared on 11- by 17 -inch AutoCAD sheets containing details of our recommendations. One electronic copy will be emailed to you followed by a hard copy in the mail Limitations of Pre -Design Geotechnical Report. We recommend performing a pre -design geotechnical evaluation to obtain subsurface soil and groundwater information related to the site. Due to the critical nature of the structures and depending on the conditions encountered, more thorough design geotechnical evaluation could be required in the future. Geotechnical items not included in this pre -design geotechnical evaluation, but could be necessary for the next phase, include the following. • A site specific spectral response analysis (Site Class E or F). • A 100 -foot deep boring. • Detailed liquefaction analysis. • Mitigation and identification of seismic hazards, if any. • Shoring and dewatering designs for the excavations. Additional Work. As previously mentioned, we are planning to use our Diedrich D-120 rig for the work, but it could also encounter auger refusal prior to reaching the 40 -foot depth. Rather than breaking equipment, it may be necessary to casing advance some of the perimeter tank borings as well. if this is necessary, the additional cost will be $65 per foot, and we will contact you for authorization. Utility Clearance. SK Geotechnical will contact the local utilities one -call number to notify the local telephone, electric, gas, sewer, water, and cable TV companies to determine the location of underground utilities. We request that you or your authorized representative notify the SK Geotechnical project manager immediately of the presence and location of any underground objects on private property which are not the responsibility of public utilities. Our services do not include subcontracting a private utility h7cattorm -conducting-additronarresea ch -to icle fi1 ther-u H, T techtucaf wrll take rcasort� ' precautions to avoid underground objects. In authorizing this contract, you agree to waive any claim against SK Geotechnical and will indemnify and hold SK Geotechnical harmless from any claim of liability, injury, or loss allegedly arising from our damaging of underground objects that were not called to our attention prior to beginning the work.
