The project engineer shall be responsible <br />for the structure's suitability to the existing site <br />conditions and for the hydraulic evaluation -- <br />including scour and confirmation of soil conditions. <br />2. Prior to construction, contractor must verify all <br />elevations shown through the engineer. <br />J. Only Bridge Tek, A Division of CONTECH Arch Technologies, Inc <br />the CON/SPAN® approved precaster in California <br />may provide the structure designed in accordance with <br />these plans. <br />4. The use of another precast structure with the design <br />assumptions used for the CON/SPAN® structure may <br />lead to serious design errors. Use of any other precast <br />structure with this design and drawings voids any <br />certification of this design and warranty. CON/SPAN® <br />Bridge Systems assumes no liability for design of <br />any alternate or similar type structures. <br />5. Alternate structures may be considered, provided that <br />signed and sealed design drawings (and calculations) <br />are submitted to the engineer 2 weeks prior to the <br />bid date for review and approval. <br />6. Proposed alternates to o CON/SPAN® Bridge System <br />must submit at least two (2) independently verified <br />full scale load tests that confirm the proposed design <br />methodology of the three sided/arch structure(s). <br />The proposed alternate, upon satisfactory confirmation <br />of design methodology, may be considered an acceptable <br />alternate. <br />DESIGN DA TA <br />Design Loading: <br />Bridge Units: HS20-44 <br />Headwalls.- Earth Pressure only <br />Wingwalls.'
