501Steel Sheet Piling

Steel Sheet Piling

Description

501.01This work consists of furnishing and driving corrugated steel sheeting or steel sheet

piling per these specifications and in conformity to the lines and grades shown on the plans or established.

Materials

501.02Type I Steel Sheet Piling shall be used where shown on the plans and shall be a

corrugated steel sheeting non-galvanized interlocking type, at least 8 gauge in thickness with a minimum section modulus of 1.300 cubic inches per unit of 12 inches in width. Steel sheeting shall conform to ASTM A857, Grade 36 for 7 gauge or 8-gauge steel, Grade 30 for heavier gauges. The sides for each piece of sheeting shall be furnished with an interlock that is continuous for the full length of the sheeting. The interlock shall have an opening of sufficient width to allow free slippage of the adjoining sheet.

501.03Type II Steel Sheet Piling shall be of the type and weight shown on the plans and shall

conform to the requirements of AASHTO M 202 or AASHTO M 270, Grade 50.

Construction Requirements

501.04Steel sheet piling shall be driven to form a tight bulkhead. A driving head shall be used

and any piling that does not provide a tight bulkhead shall be pulled and replaced at the Contractor's expense. Steel sheet piling that is full length as shown on the plans and is required to be driven below the specified cut-off elevation shall be spliced with additional steel sheet piling with a full penetration butt weld. Splicing will be limited to three per pile sheet. A splice shall not be less than 3 feet from another splice on the same pile.

Welding shall conform to the applicable requirements of ANSI/AWS D 1.1.

Where specified on the plans, sheet piling shall be painted as described in subsection 509.24.

Method of Measurement

501.05Steel sheet piling will be measured by the square foot, complete in place and accepted,

to cut-off elevation. Each approved splice will be measured as an additional 3 square feet of sheet pile. The area of sheet piling cut-off to be measured will be those random areas of sheet piling that result from cutting off the tops of driven sheet piling and not used in the work.
