REST POINT CIRCLE MOUND, MINNESOTA GENERAL NOTES 1. Soil strength parameters for this project were assumed based on a review of soils viewed by VEC at the project area and Information from the client. It Is the responsibility of the owner or owner's representative to verify the soil strength parameters provided are representative of the soils available for wall construction.If the soil strength parameters are found to be inconsistent with those used by VEC during the design,this design is no longer valid and itis the responsibility of the owner or owner's representative to notify VEC so the retaining wall system can be redesigned.Failure to notify VEC may result in failure of the retaining wall. 2. Design Soil Parameters: a.Retained soil: Imported/on-she day(CL) phi=27 degrees gamma=125 pct. b.Foundation soil: Imported/on-site day(CL) phi=27 degrees gamma=125 pcf. 3. This set of timber retaining wall plans are based on site measurements at the site,as directed by the client.If other plans are produced that contain different information than that referenced,this plan may need to be revised and/or the wall may need to be redesigned. 4. This set of timber retaining wall plans are based specifically on the wall being constructed with 6"by 5"timbers and Manta Ray soil anchors. Absolutely no substitutions allowed. 5. Location of the timber retaining walls in relation to property lines,utility easements,watershed easements,or any other type of easements are the responsibility of the owner or the she civil engineer.VEC assumes no liability for the location of the retaining wall,or if construction of the proposed retaining wall encroaches any property lines or easements. 6. It is imperative that the site surveying of the timber retaining wall be done by the she civil engineer or surveyor and must be based on computer generated site/grading plans and not profile plans done by VEC.Surveying of the retaining wall must take into account the design batter indicated on the enclosed plans and details.Failure to take into account wall batter for timber retaining wall surveying will produce incorrect locations of all SHEET INDEX top of walls and shall be corrected at no cost to VEC. SHEET NO. SHEET DESCRIPTION 7. Wall geometry,locations,slopes and surcharge loads for the timber retaining walls were assumed from the information referenced above.If conditions vary greatly in the field from those shown In these plans,VEC must be notified prior to construction of the retaining wall to review the WI TITLE PAGE 8 WALL NOTES design and/or plans.Modifications to the design and/or plans may be required after the review,and may take up to ten business days to complete.
