Email us @ info@amscrewpile.com
☑️ Click the "Contact us" button & fill out the form.
☑️ Email building plans, pictures or additional information to info@amscrewpile.com.
☑️ Schedule a worksite meeting to determine plan of action and the scope of work.
☑️ Review proposal and sign contract.
☑️ Schedule an installation date.
STEP #2
LET US HELP YOU WITH
☑️ Geotechnical Reporting - certain residential/commercial projects will require a Local Geotechnical Engineered Soil Report to determine:
the appropriate engineered pile size
number of helices & diameter of the pile shaft
load bearing soil installation depth and torque pressure to support your project.
☑️ Certified Structural engineered foundation plans. These include pile plan drawing and installation required information for permit applications.
STEP #3
CALL BEFORE YOU DIG:
☑️ A service line locate is required prior to beginning any work that requires excavation or digging into the ground deeper than 15 cm.
☑️ Private Line Locating Services: (Private Services, Sewage & Water Lines, Sprinkler, Communication or other buried lines)
Accurate Underground Utility Locating Services Ltd. @ 204-330-7538
Structure Scan Inc. @ 204-777-6590
☑️ Public Service Utility Locate Request:
A Facilities Locate document will be issued to you by the private line locating service with specific instructions that must be followed, in accordance with Government of Manitoba & Ontario statues and regulations.
If work has not started within 14 days after line location, you must have the lines re-marked and receive an updated Facilities Locate document.
City of Winnipeg Helical Pile Requirements
Table notes:
Augured piles that are evaluated by CCMC must be evaluated in cohesive soils and must bear
the CCMC evaluation number and manufacturer’s identification (including model). Installation must be carried out in conformance with the CCMC evaluation’s “conditions and limitations.” (See also attached section “Supplementary information for non-CCMC evaluated augured pile manufacturers.”)“Engineer’s Certification” is a letter of certification for the foundation provided and sealed by the foundation design engineer. (See Professional Designer’s Certificate for Housing.)
A geotechnical report must be a site-specific engineering report, sealed and signed by a Professional Engineer licensed to practice in the Province of Manitoba. The structural design shall be in keeping with the recommendations of the report.
The referenced construction types may be separate or attached to the main dwelling.
Single-storey additions with no basement, also includes 3- and 4-season sunrooms, mudrooms, porches, etc.
Accessory structures may include carports, gazebos, sheds, etc. These structures are single- storey only.
“Sealed Plans” are drawings sealed and signed by a Professional Engineer licensed to practice in the Province of Manitoba. They must indicate the manufacturer, model number and capacity of the piles. (See also attached section “Supplementary information for non- CCMC evaluated augured pile manufacturers.”)
As many of these types of piles, greater than 5000 lbs are specifically manufactured based on the geotechnical report, they may not hold a current CCMC evaluation. Enough detail on the engineer’s certification drawings/documents should be recorded to provide the reviewer sufficient information to determine compliance of the augured pile for the project and site that is being constructed. This can include, but is not limited to information such as;
Augured pile to follow geotechnical recommendations.
Negate shaft diameter for ultimate capacity/friction capacity
Multiple flights are cumulative for end bearing resistance
Installation should be below frost/or address possible frost jacking
Reference any test data that is available (actual load testing)
Reference design manuals (such as Perko, DFI)
Other information to coordinate the overall design (ie..pile caps, connections, etc)
Each augered pile evaluation must be site specific, designed according to the
associated geotechnical report and as per the project engineer’s design.
Sealed plans are required for augured piles used for supporting concentrated loads from uncovered, single-storey decks and ramps in housing applications where the structure size is more than 27.9 m2 (300 ft2) or loading exceeds 22 kN (5,000 lbs.) per pile.
Information Bulletin: 2022-001-S
Helical, augured and screw piles utilized in commercial construction applications require designs and installations to be submitted under seal of an engineer. What documents must be submitted and which engineer must be responsible for which part of the design or installation is often not well comprehended hence, the City of Winnipeg minimum submission requirements for foundations using helical, augured or screw piles (collectively referred to herein as “piles”) in commercial applications are outlined below.
A site-specific geotechnical report shall be submitted under the seal and signature of a geotechnical engineer registered in the Province of Manitoba and shall
Provide the method to compute the piles’ uplift, compressive and lateral resistance to the ULS and SLS requirements.
Provide recommendations for corrosion protection for the piles based on site specific soil conditions or confirm none is required.
Structural drawings shall be submitted and shall specify the ULS and SLS vertical downward, uplift, lateral, and moment reactions at each pile location under the seal and signature of the Engineer of Record for the project.
A letter of intent shall be submitted under seal and signature of the pile design or geotechnical engineer registered to practice in the Province of Manitoba to confirm that
He/she is retained as the professional engineer certifying that the piles will be installed as per geotechnical requirements.
A field review report will be submitted in accordance with the requirements of MBC Article 4.2.2.3, Field Review.
A final installation report will be provided consisting of pile types, depth, torque and load capacity achieved.
Documentation for the piles shall be submitted under the seal and signature of the pile design engineer registered to practice in the Province of Manitoba, and reviewed by the engineer of record, as follows:
Drawings specifying connection details, pile depth, pipe diameter and thickness, diameter and thickness, number and spacing of helixes, material grades, bracket details, pile capacities (axial down and up, lateral and moment), and references to codes and standards.
Pile layout plan, indicating pile model and locations to support the building loads provided in item 2 above.
5. Final pile shop drawings, layout plans, pile installation logs and pile certification under seal and signature of the pile design engineer and reviewed by the Engineer of Record for the project. (Final pile shop drawings and layout plans shall be resubmitted only if pile installation plans and/or pile types deviate from approved plans due to practical site constraints).
