Bayley Construction | March 12, 2025 Page 3 <br />File No. 0661-144-00 <br />We propose to complete our geotechnical services in multiple tasks. The first task will consist of providing <br />consultation, attending meetings, and preparing preliminary design values (Task 200) for the team’s use <br />during concept design. We recommend including an allowance for this scope. We will then perform a <br />geotechnical investigation with borings and prepare a draft design report (Task 300) for the team’s use <br />during schematic design. Once the private property entry agreements are obtained, we will drill two <br />additional borings (Task 301) and prepare a final version of the geotechnical report. We also propose an <br />add alternate scope (Task 302) to conduct environmental field screening, focused sampling and chemical <br />analyses during the geotechnical drilling. After issuing the final report, we plan to provide consultation to <br />the project team through design development (Task 400). <br />Scope of Services <br />Our proposed geotechnical scope of services is presented below. <br />TASK 200. PRELIMINARY GEOTECHNICAL SUPPORT <br />1.Review available reports and studies for the project site and surrounding area available from our files <br />(completed). <br />2.Attending meetings (including pull planning session on February 12, 2025) and providing consultation <br />as needed. <br />3.Providing preliminary design recommendations to the project team as needed. <br />TASK 300. GEOTECHNICAL INVESTIGATION <br />1.Coordinate site access for our proposed geotechnical investigation and contact the Washington State <br />One-Call service to locate the borings in areas that are clear of underground utilities. We will also <br />subcontract a private utility locator to clear utilities near the proposed boring locations. We will <br />subcontract a vacuum excavation contractor to air knife the upper 5 feet of the borings to look for <br />unmarked buried utilities. <br />2.Drill and sample 9 geotechnical borings to depths between 15 and 40 feet; one of the borings will be <br />converted into monitoring wells. The borings will be completed using hollow-stem auger drilling <br />equipment. The drilling depths were selected based on the proposed project site layout and the <br />anticipated subsurface conditions. The drilling will be monitored on a full-time basis by a GeoEngineers <br />field representative. We expect the geotechnical investigation to take five 10-hour days. <br />The drilling services will be subcontracted to GeoEngineers and will generate excess soil that will not <br />be replaced in the borehole. Our scope and fee estimate assumes that the excess soils, or <br />investigation- derived waste (IDW), will be drummed and stored on-site for waste profiling. <br />GeoEngineers will arrange for and subcontract disposal of the drummed IDW. Our estimated costs <br />assume disposal of 14 drums of non-hazardous waste. <br />3.Obtain traffic control signage (assuming no flaggers are needed as part of City of Everett permitting), <br />including rental and delivery for 5 days of field work. We have assumed that the City of Everett standard <br />traffic control plan #703 (shoulder work) will be used for the permitted work. <br />4.Install monitoring equipment (pressure transducers) within the well. This will allow us to measure and <br />log groundwater levels over time. <br />Design-Build Contract for Everett Outdoor Events Center <br />Exhibit C - Phase 1A Work and Fee Proposal
