INDEX OF SHEETS <br />SHEET NO. TITLE <br />W1 COVER SHEET/DESIGN INFORMATION <br />W2 WALL ELEVATION VIEW(S) <br />W3 SECTIONS AND DETAILS <br />DESIGN PARAMETERS AND PROVISIONS <br />DESIGN PROVISIONS: <br />1. REFER TO BOULDER RETAINING WALL INDUSTRY STANDARD SPECIFICATIONS AND <br />DETAILS AS THEY ARE INTEGRAL TO THIS PLAN <br />2. THE DESIGN OF THIS RETAINING WALL SYSTEM WAS BASED UPON THE EFFECTIVE <br />STRENGTH PARAMETERS SHOWN ON THE "SOIL VALUES" TABLE. UNLESS OTHERWISE <br />NOTED, NO FORMAL SOIL INFORMATION WAS PROVIDED BY THE OWNER OR OWNER'S <br />REPRESENTATIVE. IF SOIL CONDITIONS VARY AT TIME OF CONSTRUCTION, WALL <br />ENGINEER MUST BE CONTACTED TO DETERMINE IF A REVISED DESIGN IS NEEDED. <br />3. THE WALL DESIGN WAS BASED ON THE INFORMATION NOTED IN THE KEY PLAN. <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 <br />RETAINING WALL(S). UNLESS OTHERWISE NOTED, THE WALL(S) HAS NOT BEEN <br />DESIGNED FOR HYDROSTATIC SURCHARGE LOADING. <br />7. THE WALL DESIGN WAS PERFORMED USING DESIGN GUIDELINES PRESENTED IN THE <br />THIRD EDITION OF THE "DESIGN MANUAL FOR SEGMENTAL RETAINING WALLS" <br />PUBLISHED BY NCMA. <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 <br />AND/OR WORK RELATED TO HANDRAILS, GUARDRAILS, OR OTHER LIFE/SAFETY ISSUES <br />ARE EXCLUDED FROM THESE DOCUMENTS AND ARE TO BE PROVIDED BY OTHERS. <br />2. SITE LAYOUT AND GRADING DESIGN ARE NOT INCLUDED IN WALL DESIGN SERVICES. <br />THOSE 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 <br />WHICH SHOULD BE PERFORMED BY A QUALIFIED GEOTECHNICAL ENGINEER. <br />ADDITIONAL SUBSURFACE EXPLORATION MAY BE REQUIRED. <br />SUGGESTED QUALITY ASSURANCE REQUIREMENTS: <br />1. A QUALIFIED ENGINEER OR TECHNICIAN SHALL SUPERVISE THE WALL CONSTRUCTION <br />TO VERIFY SITE SOIL CONDITIONS. IF THE PROJECT GEOTECHNICAL ENGINEER DOES <br />NOT PERFORM THIS WORK, A QUALIFIED GEOTECHNICAL ENGINEER/TECHNICIAN SHALL <br />BE HIRED TO ASSURE THE RETAINING WALL IS CONSTRUCTED WITH PROPER SOIL <br />PARAMETERS. <br />2. A QUALIFIED GEOTECHNICAL ENGINEER SHALL BE CONSULTED TO VERIFY THE <br />SUITABILITY OF DESIGN ASSUMPTIONS MADE BY CRITERIUM. <br />3. WALL EXCAVATION AND SOILS SHALL BE INSPECTED FOR GROUNDWATER CONDITIONS. <br />THE GEOTECHNICAL ENGINEER SHALL DETERMINE ADDITIONAL DRAINAGE PROVISIONS <br />TO BE INCORORATED INTO THE WALL DESIGN. <br />4. THE WALL DESIGN ENGINEER SHALL BE HIRED TO PERFORM A PRE -CONSTRUCTION <br />SITE VISIT. <br />5. THE WALL DESIGN ENGINEER CAN BE HIRED FOR CONSTRUCTION OBSERVATION <br />SERVICES. <br />6. THE WALL CONTRACTOR IS RESPONSIBLE FOR MAINTAINING QUALITY CONTROL FOR <br />THE CONSTRUCTION OF THE WALL IN ACCORDANCE WITH CONTRACT REQUIREMENTS. <br />SEE PROJECT CONTRACT DOCUMENTS FOR SPECIFIC DETAILS ON THE SCOPE OF <br />WORK THAT WILL BE PROVIDED BY ALL PARTIES. <br />PLANS CREATED BY: PREPARED FOR: <br />CRITERIUM-SCHIMNOWSKI ANGELA HOPPING <br />ENGINEERS 95 SMITH AVENUE <br />161 DUNBAR WAY PHONE: 651.779.7700 ORONO, MINNESOTA <br />MAHTOMEDI, MN 55115 FAX: 651.779.7114 <br />pschimno@criterium-schimno,ki.com PHONE: 612-366-2987 <br />RETAINING WALL DRAWINGS <br />FOR <br />95 SMITH AVENUE <br />ORONO, MINNESOTA <br />ESTIMATED PROJECT QUANTITIES <br />BOULDERS*j 447 SQ.
