Article 1 — Description
Furnish and place steel H -piling, pipe piling, and sheet piling.
Article 2 — Materials
Furnish steel H -piling, pipe piling, and steel sheet piling in accordance with Item 441, “Steel Structures,” and as shown on the plans. Furnish steel that meets ASTM A690 or ASTM A572 Grade 50 for H -piling. Furnish steel that meets ASTM A572 Grade 50 for pipe piling. Furnish steel that meets ASTM A328, ASTM A690, or ASTM A572 Grade 50 for hot -rolled sheet piling. Furnish steel that meets ASTM A690 or ASTM A572 Grade 50 for cold- rolled sheet piling. Steel sheet piling may be substituted with a section modulus and minimum thickness of material equal to or greater than that of the section specified. If a hot -rolled section is specified, the substitute section must also be hot -rolled. Furnish piling in the lengths shown on the plans. The Engineer will approve lengths based on test driving data or test load data where test piling is required. Fabricate piling once the Engineer has determined the approved lengths. At the Contractor’s expense, the H -piling or pipe piling may be fabricated by welding together up to three sections of piling with a minimum section length of 5 ft. Shop- paint piling with 3.5 mils minimum dry f ilm thickness (DFT) inorganic zinc primer in accordance with System III-B or System IV paint protection system specified in Item 441, unless otherwise shown on the plans. Apply appearance or intermediate coatings only if shown on the plans. Apply a marine- grade immersion coating system recommended by the manufacturer for marine immersion service and meeting the requirements of NORSOK Standard M- 501, Coating System No. 7 for piling in marine environments. Submit a manufacturer’s certification that states the material meets the requirements of NORSOK Standard M -501, Coating System No. 7. Submit product data sheets and obtain approval of paint system before performing the work. The Department maintains an MPL of approved paint systems for steel piling. Paint the portion of the pile to be above finished grade or dredge line, in water, and a minimum distance of 15 ft. below finished grade or dredge line, unless otherwise shown on the plans. Provide coatings for field painting in accordance with Item 446, “Field Cleaning and Painting Steel.” Reinforce steel H -pile tips as directed when the piling is to be driven into rock, shale, or other material of similar hardness. Use the pile tip reinforcement detail shown on Common Foundation Details (FD) standard plans, or attach prefabricated pile points manufactured from ASTM A27 Grade 65- 35 or ASTM A148 Grade 80- 50 material. Submit construction drawings for approval when alternate pile tip reinforcements are proposed. Reinforce steel pipe piling and steel sheet piling tip as directed when piling is to be driven into rock, shale, or other material of similar hardness. Use prefabricated pipe piling or sheet piling tip reinforcements manufactured from ASTM A27 Grade 65- 35 or ASTM A148 Grade 80-50 material. Submit construction drawings for approval when alternate pipe piling or sheet piling tip reinforcements are proposed. Furnish certification documentation for the tip reinforcements conforming to this requirement. Store piling above ground on adequate blocking. Keep piling clean and always fully drained during storage. 488 3. CONSTRUCTION Drive piling in accordance with Item 404, “Driving Piling.” Test load, when required, in accordance with Item 405, “Foundation Load Test.”
3.1 Splices and Cutoffs . Make all splices for steel H -piling shown on Common Foundation Details (FD)
standard plans . Submit pipe piling and sheet piling splicing locations and details for approval. Drive spliced piling the additional depth required as soon as the splice is completed if the required penetration or bearing resistance has not been obtained. Cut piling off square at plan grade or to the established grade after driving it to the approximate penetration and bearing resistance required. Cut off the damaged portion if the head of the pile is appreciably distorted or otherwise damaged below cutoff level, and splice an undamaged section in its place, at no addit ional expense to the Department. Weld in accordance with Item 448, “Structural Field Welding.”
3.2 Painting . Spot -clean and paint in accordance with Item 446. Clean and paint damaged areas, field splices,
or areas missing the shop coat with enough epoxy zinc primer to bring the total zinc primer to the minimum 3.5-mil DFT. Follow the repair procedures recommended by the manufacturer of the marine- grade immersion coating system for piling with marine- grade immersion coatings. After driving piling, apply at leas t 2.0 mil DFT of each of epoxy intermediate and polyurethane appearance coating when System III- B is shown on the plans , or apply at least 2.0 mil DFT of the acrylic latex appearance coating when System IV is shown on the plans. Use an appearance coating m eeting Federal Standard 595C, Color 35630, unless shown otherwise on the plans. Extend the appearance coat 1 ft. below finished ground line unless the piling is standing in water, in which case extend the appearance coat to the low-water line. Replace any earthen material removed for this painting after the paint has dried.
3.3 Test Piling . Test piling must meet requirements for steel piling. The Engineer may adjust the number of test
piling to secure desired information.
Article 4 — Measurement
4.1 Steel H -Piling and Pipe Piling .
4.1.1 Steel Piling . “Steel H -Piling,” “Steel H -Test P iling,” “Steel P ipe Piling, ” and “S teel P ipe-Test P iling” will be
measured by the foot of acceptable piling in place after all cutoffs and splices have been made. When the Contractor elects to drive piling deeper than required to meet the specified length and bearing requirements, no measurement will be made on that portion below the elevation at which length and bearing requirements were first obtained.
4.1.2 Splices . Splices will be measured by each authorized splice made necessary by driving beyond the plan pile
length to obtain the required bearing resistance.
4.1.3 Reinforced Tips . Reinforced tips will be measured by each pile tip when required.
4.2 Steel Sheet Piling .
4.2.1 Steel Piling . Steel sheet piling will be measured by the square foot of acceptable piling in place . Sheet piling
driven below the elevation required as shown on the plans or the elevation authorized by the Engineer will not be measured for payment.
4.2.2 Reinforced Tips . Reinforced tips will be measured by each pile tip when required.
489 5. PAYMENT No direct payment will be made for painting or excavation and backfill required for the painting of portions of piling below ground line. Payment for all work and materials required by these i tems will be included in the unit price bid for “Steel H -Piling,” “Steel H -Test Piling,” “Sheet Piling,” “Steel Pipe Piling,” or “Steel Pipe Test Pile.” The unit price bid is full compensation for jetting, pilot holes, alignment holes, driving piling, painting, materials, tools, equipment, labor, and incidentals. Any test load ordered by the Engineer that is not provided for in the Contract will be paid for in accordance with Article 9.7., “Payment for Extra Work and Force Account Method.”
5.1 Steel H -Piling and Pipe Piling .
5.1.1 Steel Piling . The work performed and materials furnished in accordance with this Item and measured as
provided under “Measurement” will be paid for at the unit price bid for the specified size and weight of “Steel H-Piling,” “Steel H -Test Piling,” “Steel Pipe Piling,” or “Steel Pipe Test Piling.”
5.1.2 Splices . Payment for each completed authorized splice for both regular and test piling, regardless of buildup
length, will be made at a price equal to four times the unit price bid for “Steel H -Piling” or “Steel Pipe Piling.”
5.1.3 Cutoffs . Cutoffs will not be paid for directly, but will be subsidiary to this Item.
5.1.4 Reinforced Tips . Payment for each completed authorized pile tip for both regular and test piling will be
made at a price equal to two times the unit price bid for “Steel H -Piling” or “Steel Pipe Piling.”
5.2 Steel Sheet Piling .
5.2.1 Steel Piling . Steel sheet piling will be paid for at the unit price bid per square foot for “Sheet Piling” of the
type shown on the plans. No payment will be made for cutoffs or splices of sheet piling.
5.2.2 Reinforced Tips . Payment for each completed authorized pile tip will be made at a price equal to two times
the unit price bid for “Steel Sheet Piling.”
