Section 263. — SOLDIER PILE RETAINING WALLS

(ADDED SECTION)

Description

263.01 This work consists of constructing permanent soldier pile retaining wall.

Material

263.02 Conform to the following Sections and Subsections:

Drilled Shafts 565 Geocomposite Drain 714.02 Lean Concrete Backfill 614 Permanent Ground Anchors 256 Piling 715 Reinforcing Steel 554 Steel Structures 555 Structural Concrete 552 Timber Structures 557 Underdrains, Sheet Drains, and Pavement Edge Drains 605

Construction Requirements

263.03 Qualifications. Submit the following for acceptance at least 30 days before drilling for soldier piles. Acceptance of the Contractor’s personnel and installation plan does not relieve the Contractor of the responsibility for obtaining the required results in the completed work.

(a) Professional engineer. Provide an on-site professional geotechnical engineer, professional engineering geologist, or professional geologist with at least 3 years of experience in the design and construction of soldier pile walls or drilled shafts to log subsurface profiles.

(b) Other personnel. A résumé for each individual describing their experience on at least 5 soldier piles retaining wall projects of similar scope and complexity over the past 5 years.

Include project names, locations, and contract information for project owners.

263.04 General. Check existing site conditions for conformance with the plans. Provide logs of material condition descriptions from roadway surface to bottom of drilled shafts.

Verify limits of wall installation. Backfill according to Section 208.

If proposing an alternate construction method, submit to the CO for approval 14 days prior to beginning of construction according to Subsection 104.03. See Section 257 for Contractor-designed retaining walls.
