APPROACFI <br /> _ :` <br /> "�' EXHIBIT A -- SCOPE OF 1NORK <br /> BkF <br /> Task ld. Evaluation of Alternatives I <br /> Based on design details and criteria from ENGEO, BKF wilt lead a conference oall I <br /> discussion-for evaluation af three different alternatives; (1) reinforced earth embankment, � <br /> (2) grouted xip-rap and (3) sea�vall. Imp�ovement goals will be to cost effectively limit <br /> futare erosion. We assume the minimum leves crest elevation is outside the limits of work, <br /> however by limiting the future erosion, the levee crest elevations will be preserved. If the <br /> City detezmin.es that the levee elevations should be evalnated, at the City's request, <br /> evaluation and design of the levee can be provided as an additional service. <br /> Deliverables: � <br /> A brief e-mail summaz�zing the conference call discussion will be provided. <br /> Task le. �Ynal Basis of Design Memorandum ; <br /> � <br /> Not included ! <br /> i <br /> Task 1--GeotecHnical Services <br /> ENGEO will perfarna a site visit and collect a sample ofnear-surface soit from the repair <br /> area and perform gradation testing and provide filter design criteria. <br /> �or design alternatives selected by BKF,ENGEO will assist in any geotechnical criteria <br /> and qualitatively discuss advantages or disadvantages from a geoteclmical perspective. <br /> ENGEO will provide this information in the faxm of a ietter. <br /> Task 2.Construction Documents <br /> Task 2a, Preliminary Consiruction Doeuments <br /> Preliminary constrttction docwnents will be prepared for the improvements to the project <br /> area. We assume drawings wiil be at 40-scale. The plans will utilize existing City <br /> standard details as appropriate. Caltrans and"Green Book" standard det�ils will be used <br /> where City standard details are not appropriate. Technical specifications will be included ' <br /> on the plans,as appropriate. FHWA standards and details far design of rip-rap revetment . <br /> will serve as flie basis of design. We assume an informal bid process will be usecl. <br /> Design review tneetings are included for the prelirninary submittal. Construction cost <br /> updates will he provided for#his snbmittal. <br /> Deliverables: <br /> Preliminazy Plans and Cost Estimates will be provided to the City. <br /> --.�......__ ___......__.._......__.............._.........._....._..:..__.._.__.._.._....._......._.............._.._._.._....._.,_.._._._.__............_.._._____.._..___..___...._.._.__...._._.....�._---_...._..._._.. <br /> City of Red�rood City—Seapori Cenire Rip-Rap Replacement ProJect 850.482.6300 <br /> Date:September 9,2010(revised 8l30110) ��nw�.bkf.com <br />
