2525 Dunwoody Avenue, Wayzata, Minnesota <br />February 9, 2024 <br />Page | 6 <br />DESIGN PARAMETERS AND PROVISIONS <br />DESIGN PROVISIONS: <br />1. REFER TO BOULDER RETAINING WALL INDUSTRY STANDARD SPECIFICATIONS AS THEY ARE <br />INTEGRAL TO THIS PLAN <br />2. THE DESIGN OF THIS RETAINING WALL SYSTEM WAS BASED UPON THE EFFECTIVE STRENGTH <br />PARAMETERS SHOWN ON THE “SOIL VALUES” TABLE. UNLESS OTHEWISE NOTED, NO FORMAL <br />SOIL INFORMATION WAS PROVIDED BY THE OWNER OR OWNER’S REPRESENTATIVE. IF SOIL <br />CONDITIONS VARY AT TIME OF CONSTRUCTION, WALL ENGINEER MUST BE CONTACTED TO <br />DETERMINE IF A REVISED DESIGN IS NEEDED. <br />3. THE WALL DESIGN WAS BASED ON THE INFORMATION NOTED IN THE LETTER ABOVE. <br />4. REFER TO WALL CALCULATIONS FOR BEARING CAPACITY REQUIREMENTS. <br />5. NO PRODUCT/MATERIAL SUBSTITUTIONS WILL BE ALLOWED WITHOUT PRIOR WRITTEN <br />PERMISSION OF CRITERIUM-SCHIMNOWSKI ENGINEERS. <br />6. FINAL SITE GRADES AND ROOF DRAINS SHALL DIRECT RUNOFF AWAY FROM ANY RETAINING <br />WALL(S). UNLESS OTHERWISE NOTED, THE WALL(S) HAS NOT BEEN DESIGNED FOR <br />HYDROSTATIC SURCHARGE LOADING. <br />7. THE WALL DESIGN WAS PERFORMED USING DESIGN GUIDELINES PRESENTED IN THE THIRD <br />EDITION OF THE "DESIGN MANUAL FOR SEGMENTAL RETAINING WALLS" PUBLISHED BY NCMA <br />AND FHWA ROCKERY DESIGN AND CONSTRUCTION GUIDELINES. <br />DESIGN LIMITATIONS: <br />1. THE INFORMATION PROVIDED WITHIN THESE DOCUMENTS IS FOR THE STRUCTURAL <br />DESIGN OF THE PROPOSED RETAINING WALL(S) ONLY. THE REQUIREMENTS FOR AND/OR WORK <br />RELATED TO HANDRAILS, GUARDRAILS, OR OTHER LIFE/SAFETY ISSUES ARE EXCLUDED FROM <br />THESE DOCUMENTS AND ARE TO BE PROVIDED BY OTHERS. <br />2. SITE LAYOUT AND GRADING DESIGN ARE NOT INCLUDED IN WALL DESIGN SERVICES. THOSE <br />SERVICE ARE THE RESPONSIBILITY OF THE SITE CIVIL ENGINEER. <br />3. INTERNAL COMPOUND STABILITY (ICS) HAS BEEN CALCULATED FOR THIS PROJECT BY <br />CRITERIUM. HOWEVER, ICS IS NOT A SUBSTITUTE FOR A GLOBAL STABILITY ANALYSIS WHICH <br />SHOULD BE PERFORMED BY A QUALIFIED GEOTECHNICAL ENGINEER. ADDITIONAL SUBSURFACE <br />EXPLORATION MAY BE REQUIRED. <br />SUGGESTEDQUALITY ASSURANCE REQUIREMENTS: <br />1. A QUALIFIED ENGINEER OR TECHNICIAN SHALL SUPERVISE THE WALL CONSTRUCTION TO <br />VERIFY SITE SOIL CONDITIONS. IF THE PROJECT GEOTECHNICAL ENGINEER DOES NOT PERFORM <br />THIS WORK, A QUALIFIED GEOTECHNICAL ENGINEER/TECHNICIAN SHALL BE HIRED TO ASSURE <br />THE RETAINING WALL IS CONSTRUCTED WITH PROPER SOIL PARAMETERS. <br />2. A QUALIFIED GEOTECHNICAL ENGINEER SHALL BE CONSULTED TO VERIFY THE SUITABILITY OF <br />DESIGN ASSUMPTIONS MADE BY CRITERIUM. <br />3. WALL EXCAVATION AND SOILS SHALL BE INSPECTED FOR GROUNDWATER CONDITIONS. THE <br />GEOTECHNICAL ENGINEER SHALL DETERMINE ADDITIONAL DRAINAGE PROVISIONS TO BE <br />INCORORATED INTO THE WALL DESIGN. <br />4. THE WALL DESIGN ENGINEER SHALL BE HIRED TO PERFORM A PRE-CONSTRUCTION SITE VISIT. <br />5. THE WALL DESIGN ENGINEER CAN BE HIRED FOR CONSTRUCTION OBSERVATION SERVICES. <br />6. THE WALL CONTRACTOR IS RESPONSIBLE FOR MAINTAINING QUALITY CONTROL FOR THE <br />CONSTRUCTION OF THE WALL IN ACCORDANCE WITH CONTRACT REQUIREMENTS. <br />7. SEE PROJECT CONTRACT DOCUMENTS FOR SPECIFIC DETAILS ON THE SCOPE OF WORK THAT <br />WILL BE PROVIDED BY ALL PARTIES.
