THE DESIGN CONTAINED ON THESE DRAWINGS IS BASEDON INFORMATION PROVIDED BY THE OWNER. ON THEBASIS OF THIS INFORMATION, THE HILFIKER COMPANYHAS DESIGNED, AND IS RESPONSIBLE FOR THE INTERNALSTABILITY OF THE STRUCTURE ONLY. EXTERNALSTABILITY, INCLUDING FOUNDATION AND SLOPESTABILITY, IS THE RESPONSIBILITY OF THE OWNER.

SCALE: 1":40'

1. Design is based on the assumption that backfill within the reinforced soil mass,methods of construction and quality of materials conform to the requirements ofHilfiker Retaining Walls.

2. Assumed Soil Characteristics:Wall Backfill:

Unit Weight: 120 pcfInternal Friction Angle: 36°Cohesion = 0 psf

Retained Backfill:Unit Weight: 120 pcfInternal Friction Angle: 36°Cohesion = 0 psf

Foundation Soils:Unit Weight: 120 pcfFriction Angle for Sliding: 36°Cohesion = 0 psf

Traffic Surcharge -LL (Typical Traffic Load) 250 psf, occasional small trucks

If actual characteristics, grades or dimensions of soil materials differ from thoselisted above or shown on the plans, Hilfiker Retaining walls shall be notified toevaluate the need to redesign.

3. If during construction, the wall location, structure location or loads are differentthan that proposed in this plan set and calculation package, HRW shall benotified to evaluate the need for a redesign.

4. The design requires a non-saturated backfill. Surface and sub-surface drainagecontrol may be required to prevent saturation of the backfill or relieve hydrostaticpressures.

Drainage control shall be as specified in the project plans and specifications oras directed by the engineer.

5. Design Procedure:Mechanically Stabilized Earth walls and Reinforced Soil Slopes, FHWA reportNo. FHWA-NHI-00-043.

6. All information hereon is derived from the reference drawings, and is subject togeometric and geotechnical confirmation. The applicable Hilfiker constructionguide and specifications are an integral part of this submittal.

7. Hilfiker Retaining Walls shall be responsible only for the internal stability of theretaining wall, and not for global stability or foundation bearing capacity. Theowner/contractor shall be responsible for all job site drainage, safety and fallprotection provisions for workers in compliance with OSHA and any otherapplicable requirements.
