Section 263. — SOLDIER PILE RETAINING WALLS

(ADDED SECTION)

12/12/21–FP14

Description

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

Material

263.02 Conform to the following Sections and Subsections:

Driven Piles 551 Geocomposite Drain 714.02 Lean Concrete Backfill 614 Paint 719 Permanent Ground Anchors 256 Piling 715 Reinforcing Steel 709.01 Select Granular Backfill 704.08 Steel Structures 555 Structural Concrete 552 Timber Structures 557

Construction Requirements

263.03 Qualifications. Submit the following for acceptance at least 30 days before start of work 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) Supervisor and foreman. A résumé for each individual describing their experience on at least 2 soldier piles retaining wall projects of similar size and complexity over the past 5 years.

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

(b) A résumé for each professional engineer or professional engineering geologist with at least 5 years of experience in the design and construction of ground anchors soldier pile retaining walls. The on-site engineer or geologist does not need to be a licensed Professional Engineer or Professional Geologist in the state, if they have at least 2 years of experience in the design and construction of ground anchors soldier pile retaining walls working under the direct supervision of the above-referenced professional engineer/engineering geologist.

263.04 Submittals. At least 30 days before starting the soldier pile wall installation work, submit the following according to 104.03:

(a) Start date;

Revised by Amendment A003

F-14 DIVISION 250

Special Contract Requirements Project: AK FS CNF 1015(2), Russian River Campground Access, Phase 2

(b) Equipment and methods of excavation to ensure adequate advancement to the proposed depths suitable to the anticipated site and subsurface conditions, maintain wall and slope stability, and perform cleanout of the hole. Include a containment and disposal plan for excavated material and drilling slurry;

(c) Retaining wall construction sequence;

(d) Soldier pile types and sizes, if proposing alternative to materials specified in the plans.

Provide details of soldier pile placement including internal support bracing and centralization methods;

(e) Details of concrete placement including proposed operational procedures for pumping and/or tremie methods;

(f) Drilling method and materials for ground anchors according to Subsection 256.04, where ground anchors are shown in the plans;

(g) Temporary lagging design details, including locations of pre-drilled holes in piles for lagging screws and timber attachment, and backfill materials and method of installation.

Provide appropriate details of how subsurface drainage is to be accommodated, such as using a geocomposite drain or the use of free-draining backfill, if the lagging cannot be installed tight up against an even soil surface. If free-draining backfill is proposed, describe when and how the backfill will be placed and maintained in placed during top-down construction.

263.05 General. Check existing site conditions for conformance with the plans. Provide logs from on-site engineer or geologist of material condition descriptions from roadway surface to bottom of drilled shafts.

Excavate according to Section 209. Backfill according to Section 208.

Verify limits of wall installation. Submit installation drawings according to Subsection 104.03.

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

263.06 Soldier pile installation. Provide steel beams conforming to the plans or approved drawings. If driven piles are specified, then conform to Section 551. Field cutting steel beams is not allowed. Drive or drill pile, as specified, to the “bottom of pile” or “bottom of shaft” elevation shown on the plans. When pre-drilling, do the following:

(a) Drill through material to “bottom of shaft” elevation as shown in the plans. When caving conditions are encountered, do not excavate further until the Contractor has implemented the method to prevent ground caving as described in their submittal. Do not leave more than 2 inches of loose or disturbed materials in the bottom of the hole for soldier piles with permanent ground anchors, or more than 12 inches of loose material for soldier piles with without permanent ground anchors.
