Product information

Product name

Ram Jack Helical Foundation Systems and Devices

Product description

The products consist of a lead (shaft) section with helical-shaped blades that have an extension with or without helical blades. The lead section and the corresponding extension consist of a 73 mm or an 89 mm outside diameter steel pipe that has a nominal wall thickness of 5.51 mm or 6.35 mm, respectively.

The lead and extension sections are connected by a solid internally threaded pin and box connection that is welded on the trailing end of the lead section and each end of the extension. Helical-shaped blades that are shop welded to the shaft advance the pile into the soil when rotated. The helical blades are 203 mm, 254 mm, 305 mm or 356 mm in diameter and are 9.5 mm or 12.7 mm thick. The helical blades are pressed using a hydraulic press and die to achieve a 76-mm pitch prior to being welded to the lead (shaft) section.

The lead shaft and extensions are coated with a polyethylene copolymer coating with a minimum coating thickness of 0.46 mm.

  Conditions and limitations

The CCMC’s compliance opinion is bound by this product being used in accordance with the conditions and limitations set out below.

  • The product under this evaluation is intended to be used as a foundation system to support the following types of construction:
    • Single storey residential buildings within the scope of Part 9 of NBC 2015;
    • Accessory buildings such as sheds, gazebos, sunrooms, carports, and decks/porches within the scope of Part 9 of NBC 2015.

    Other applications are beyond the scope of this evaluation, wherein a professional engineer skilled in such design and licensed to practice under the appropriate provincial or territorial legislation must determine the pile capacity and other design parameters.

  • The product may be used as a foundation system to support various constructions provided that it is installed according to the manufacturer’s current instructions and within the scope of this Evaluation Report.
  • Where the product is installed in granular soil or silt, there is a direct relationship between the applied torque and the allowable compressive loads, which are indicated in the tables:
  • Where the product is installed in a cohesive soil such as clay, the relationship between the applied torque and the allowable compressive load is not predictable; as such, the allowable compressive loads must be confirmed by on-site load tests. These load tests are also required if the allowable loads exceed those stated in the tables under the Technical information section. The tests must be conducted under the direct supervision of a professional geotechnical engineer skilled in such design and licensed to practice under the appropriate provincial or territorial legislation.
  • In all cases, a registered professional engineer skilled in such design and licensed to practice under the appropriate provincial or territorial legislation must determine the number and spacing of the auger-installed steel piles required to carry all the loads. A certificate attesting to the conformity of the installation and the allowable loads for the piles must be provided.
  • All welding is to be done by welders that are certified.
  • Where conditions (soil and environmental) are determined to be corrosive to steel, protection of the steel shall be provided. The determination of the presence of corrosive conditions and the specification of the corrosion protection shall be carried out by a registered professional engineer licensed to practice under the appropriate provincial or territorial legislation”. If the determination of the presence of corrosive conditions is not completed before installation, the product, including all its accessories, is required to be hot-dipped galvanized, meeting the requirements of CAN/CSA-G164 (ASTM A123/A123M-17) with a minimum thickness of 610 g/m2, or another method that provides an equivalent level of protection and abrasion resistance deemed acceptable by CCMC.
  • The installer must be certified by Ram Jack Distribution Systems to be permitted to install the product. The installer must follow the manufacturer’s installation instructions, use approved equipment, and heed the uses and limitations specified in this Report. Each installer must carry a certification card with their signature and photograph.
  • Each product of auger-installed steel pile must be identified with a label containing the manufacturer’s identification and the phrase “CCMC 14039-R.”

  Technical information

This evaluation is based on demonstrated conformance with the following criteria:

CCMC-TG-316615.13-15ACCMC Technical Guide for Augered-Installed Steel Piles

General

Ram Jack Distribution Systems provide the products in diameters of 73 mm or 89 mm. The piles were tested in accordance with:

  • ASTM D1143-81(1994)e1, “Standard Test Method for Piles under Static Axial Compressive Load,” and
  • ASTM D3689-90(1995), “Standard Test Method for Individual Piles Under Static Axial Tensile Load.”

The installation torque is directly used to calculate the allowable bearing capacity of the pile by applying the direct correlation method. For the allowable compressive and tensile loads noted in the tables below, the factor of safety is 2.

The protective coating used on the piles was also tested; it performed well during the tests.

Code compliance as an acceptable solution

Code Compliance via Acceptable Solutions

If a building design (e.g. material, component, assembly or system) can be shown to meet all provisions of the applicable acceptable solutions in Division B (e.g. it complies with the applicable provisions of a referenced standard), it is deemed to have satisfied the objectives and functional statements linked to those provisions and thus to have complied with that part of the Code.

National Building Code of Canada, Sentence A-1.2.1.1.(1)(a)

The CCMC has determined that compliance with this provision of the Code has been demonstrated as an Acceptable Solution. The evaluation report provides a summary of the basis of CCMC's compliance opinion.

CCMC's code compliance opinions

All CCMC evaluation reports are opinions of code compliance established in accordance with the National Building Code of Canada, Subsection 1.2.1. "Compliance with this Code," which requires compliance to be achieved by:

  • complying with the applicable acceptable solutions in Division B, or
  • using an alternative solution that will achieve at least the minimum level of performance required by Division B in the areas defined by the objective and functional statements attributed to the applicable acceptable solutions.

The CCMC assesses compliance with Canadian building, energy and safety codes, and is trusted by over 6,000 regulators across Canada.

Code compliance as an alternative solution

Code Compliance via Alternative Solutions

Where a design differs from the acceptable solutions in Division B, then it should be treated as an "alternative solution." A proponent of an alternative solution must demonstrate that the alternative solution addresses the same issues as the applicable acceptable solutions in Division B and their attributed objectives and functional statements. However, because the objectives and functional statements are entirely qualitative, demonstrating compliance with them in isolation is not possible. Therefore, Clause 1.2.1.1.(1)(b) identifies the principle that Division B establishes the quantitative performance targets that alternative solutions must meet. In many cases, these targets are not defined very precisely by the acceptable solutions [...] Nevertheless, Clause 1.2.1.1.(1)(b) makes it clear that an effort must be made to demonstrate that an alternative solution will perform as well as a design that would satisfy the applicable acceptable solutions in Division B—not “well enough” but “as well as.”

National Building Code of Canada, Sentence A-1.2.1.1.(1)(b)

The CCMC has determined that compliance with this provision of the Code has been demonstrated as an Alternative Solution. The evaluation report provides a summary of the basis of CCMC's compliance opinion.

CCMC's code compliance opinions
