A. PREBID PHASE 1. Make necessary preliminary field studies and investigations, and verify all drawings, descriptions, studies, and other data supplied by the Owner for Engineer's use which, in the opinion of the Engineer, are critical to the process and mechanical design of the project, In addition to illl other necessary field study and investigation, specific an~lysis shall be done and a recommendation formulated based upon economy and ade- quacy of service, 011 the following matters: o The type of material and construction to be used in the trickling filter wall. o The type of ma teri a 1 and cons cruct i on to be used for the screening building, o The desirability, from a reliability standpoint, of using two smaller screw conveyors for screening disposal, as opposed to one large screw conveyor. o The desirability and practicality of delaying the complete installaticr, of all the aeration discs necessary to treat the design load and instead sequentially adding aeration discs, as necessary, to satisfy the oxygec requirements dS the facil ity loading increases from current levEls to design capacity, Engineer should reference dnd satisfy Article III, Section 3.3 of the Merico/City of Paris, Wastewater Treatment AgreemEnt, when conducting this analysis. 2. Prepare a basis of Design Memorandum which includes: o A description of project concept and intended results, o A general description of existing facilities and a more detailed description of Ilew or modified facilities. For each individual new or modified treatment unit, mechanical informa- tion such as, but not limited to, dimensional size, volume, aeration capacity and distribution, horsepower, equipment model, manufacturer and performance requirements shall be specified, as appropriate depending on the process unit under consideration. o Field information such as dimensions and elevations to exist- ing facilities where critical, approximate dimensions, locations and elevations of other new or existing facilities, o Process design criteria for each individual treatment unit, such as flow, detention time, recycle rates, relevant A-2 .............,,(l.,.
