TYPICAL EXCAVATION LIMITS FOR RETAINING WALLS

HILFIKER WELDED WIRE WALLS - GENERAL NOTES

1. WORK - Under the provisions of Specification 613A, the contractor has the option of selecting among a variety of wall systems, subject to the

Hilfiker Retaining Walls ). If the contractor elects to use a wall met. As designed herein, the work consists of a welded wire retaining wall constructed in accordance with these specifications and the "Welded lines, grades, design, and dimensions shown on the plans or established by the Engineer.

2. MATERIALS - The contractor shall make his own arrangements to purchase the welded wire retaining wall elements, and all necessary attachments for the complete wall. For information concerning purchase and delivery of such materals, contact Hilfiker Retaining Walls, P.O. Box 2012, Eureka, Ca. 95502-2012; Toll Free ( 800 ) 762-8962. It should be noted that the company provides free technical assistance to the project site.

3. METHOD OF MEASUREMENT AND BASIS OF PAYMENT - The welded wire retaining wall shall be measured by the number of square feet of facing in place and accepted. No separate measurement will be made for the structure excavation, backfill, or embedment lengths. Payment under item 613A(01), at the contract price, shall be full compensation for 1) excavation, 2) furnishing the welded wire and accessories, labor, tools, and the plans, and 7) other incidentals necessary to complete the work identified by the plans, specifications, and Engineer.

4. WALL EXCAVATION - Typical excavation limits shall be as shown in the plans. The excavation shall be sloped to provide safety for construction workers and inspection personnel. Boulders, logs, and any other unsuitable materials encountered shall be removed and disposed of in areas approved by the Engineer. All suitable excavation material shall be contained in the work areas or on the adjacent roadway and shall not enter adjacent streams.

5. FOUNDATION APPROVAL - Prior to wall placement the foundation shall be level and smooth and compacted to 95% of AASHTO T-180, Method C or D.

The foundation shall be approved by the Engineer before any retaining wall elements are installed.

6. WALL PLACEMENT - The welded wire elements shall be set to the lines and grades shown on the drawings or directed by the Engineer. Wall tiers shall be battered 1:48. Wall placement shall be in accordance with the "Welded Wire Construction Guide" referred to in note (1) above.
