MY of Santa Ana - Field exploration including coring, drilling, and sampling at three locations to the maximum drilled depth of 10 feet below ground surface within the limits of the project site. Upon raceipt of notice to proceed, a site visit will be performed to mark the oore/boring locations and evaluate access conditions for dotting equipment. Wilidan will call USA for underground utility locating at toast 48 hours before any Heid work is performed. However, all available subsurface utility Information should be provided/ ldentHled priorto initiating field ex- ploration to reduce the potential for damaging existing utilities. Traffic control will be provided during drilling. Boringstoores will be measured and visually logged in the field by an experienced representative. The log will Include pavement sections thicknesses and subgrade conditions. The samples will be transported to Will - dons gooteohnicai laboratory for testing. ■ Laboratory testing of collected representative subgrade soils will determine their index and engineering prop- erties. Option A: Geotechnical Investigation will be used to identify the sol properties for the trenching and backfill of proposed utllfties. - Option B: Providing recommendations for alternative new pavement sections. ■ Option B: Performing a percolation test within a boring drilled to a depth between Send 10 feat for BMP and green MSubtask 4.03 Detiverabtas streets Implementation (Kneaded). - Throe hard copies of draft gooterohnicat Providing a draft report and presenting our findings, conclu- report and one electronic PDF copy sions, and recommendations for review by the City. After - Three haul copies of final geotechnical receiving the City's oornments, a final report Incorporating report and one electronic PDF copy the comments will be provided to the City. The report will be supported with a map Illustrating boring/oom to - cations and a summary of laboratory test results. Subtask 4.04 — Preliminary Design Report Wilidan will compile a Preliminary Design Report (PDR) for review and approval by the fifty. The report will contain a summary of IN Subtask 4.04 Deliverables the Initial reconnaissance notes, utility provided information, field survey Preliminary Design Report findings, any photographs of conditions for discussion, and the base de- sign concept with preliminary construction cosi estimate. The report will be discussed with City represents- tives to make reliable, cost effective decisions about the proposed street Improvemente, water and sewer re- habilliationfrepiacement methods. During preparation of the PDR, Willdan will review existing information, such as the pavement management report, city sewer and water documents and field review of the street to make recommendations regarding i the construction needs, including the location and extend of missing or damaged sidewalk, curbs and gutter, access ramps, driveways, sewer and water repairs. In addition, the report will address the disposition of existing utillties and coordination, and anticipated requirements. Task 6 — Plans, Specifications, and Engineer's Estimate - Option A and Option 8 Subtask 5.01 — Construction Pians. Wllidan will prepare conceptual plans for City review, oom- ® Task 6.01 Dailverables ment and approval. Upon approval of the concept plans, - Three hard copies of full-size conceptual pian the final design phase will be initiated. Wllidan will submit layout and one electronic PDF format plans at the 30-, 60-, and 100-peroant levels of comple- o Three hard copies of full-size and half-size plan j tion. The City will provide review comments at all design submittals at 30-, s0-, and 100 -percent compta. stages. Wiildan will address comments received from the tion milestones, one electronic PDF copy, and submittal reviews, including comments received from one electronic Mierostation copy In Val format, i other affected agencies and utilities. Willdan will submit one, original, signed set of full-sized plans, a signed, un- bound, set of final specifications, and a copy of the final engineer's opinion of construction cost to the City. One set of Mylars will be produced after 100% plans are approved by 1he City (upon request). Plans will conform to City standard plans and CARD standards and be prepared utilizing Microstation V81 software. Option A: The plans be prepared In sufficient detail to bid the rehabilitation of the Identified well — method to be determined by the City after review of the assessment report — and the proposed sewer and water facilities. Util- Ity plans will be drafted at 40 -scala and plans will display all referenced standard plans Including trenching de- tails. Option B: The plans will consist of a Title Sheet/ Typical notes, roadway Plans, Construction Details, Signing r and Striping, landscape, and Stone Water Blofiltratlon (it required In complete streets).
