Geotechnical Explorations. Xxxxxx-Xxxx will subcontract with a geotechnical subconsultant (“Geo-Tech”) to provide geotechnical investigations for the project. Geo-Tech’s scope of services for this project will consist of the following:
Geotechnical Explorations. The County has asked that we provide a geotechnical exploration coordination and oversight services for three slope failures at Slab Creek Road, Cape Lookout Road, and Xxxxx Road that have put adjacent roads at risk of losing a lane to continued movement due to erosion and/or undercutting of the slopes. Specific services to be completed include the following items. • Coordinate clearance of existing site utilities via the One-Call Service. • Subcontract and coordinate a drilling subcontractor to complete five (5) borings: – At Slab creek road: one (1) mud rotary/HQ3 core boring 50 feet below existing ground surface (bgs), and one (1) mud rotary/HQ3 core boring 25 feet bgs; – At Cape Lookout Road: one (1) mud rotary/HQ3 core boring 70 feet bgs; – At Xxxxx Road: one (1) mud rotary/HQ3 core boring 75 feet bgs, and one (1) mud rotary/HQ3 core boring 30 feet bgs; and – At Evergreen Drive: one (1) mud rotary/HQ3 core boring 40 feet bgs. • Observe drilling by a subcontractor of six boring locations at four sites. xxx.xxxxxxxxxxxx.xxx • Obtain samples at representative intervals from the explorations using Standard Penetration Test (SPT), Dames and Xxxxx, or Xxxxxx tube methods, observe groundwater conditions, and maintain detailed logs of each exploration in general accordance with the American Society for Testing and Materials (ASTM) Test Method D 2488. • Provide project management and support services, including staff coordination, subcontractor coordination, and telephone consultations with the design team and County staff. Assumptions • Tillamook County personnel will xxxx xxxxxx locations prior to us contacting the One-Call Service. • Field work for the three sites will be completed consecutively. One drilling mobilization is assumed. Separate mobilizations will result in increased costs. • Geotechnical field work at all locations can be completed in 5 days during the hours of 7 a.m. to 6 p.m. • Traffic control will be provided by Tillamook County and one lane will be closed during drilling. • Tillamook County will provide any required permits at no cost to Xxxxx & Xxxxxxx and provide site access. • No contaminated soils will be encountered. • Soil cuttings will be drummed and disposed of off site by the drilling contractor. • Borings will be located in the field by measuring from site landmarks. Xxxxx & Xxxxxxx will not survey the boring locations.
