MICROPILE GRADE BEAM (SPECIAL)
1.0 GENERAL
This project includes construction of an array of micropiles connected to a grade beam, knee
wall, footing, or leveling course, which serve to stabilize existing or potential slope instability
and support future wall construction or roadway widening. A micropile is a small diameter,
drilled and grouted non-displacement pile. Micropiles are designed and constructed with
reinforcing casing and typically a center reinforcing bar. Design and construct micropiles
with the required capacity in accordance with the contract and accepted submittals. Use a
prequalified Micropile Subcontractor for micropile work. Define "pile" as a micropile and
"footing" as a micropile grade beam, knee wall, footing, or leveling course.
2.0 MATERIALS
Refer to the Standard Specifications.
Item Section
Reinforcing Steel 1070
Portland Cement Concrete, Class A 1000
Steel casings may be new "Structural Grade" steel pipe free from dents, cracks, cuts or any
other defects. All steel for micropiles shall meet the requirements of Article 106-1 of the
Standard Specifications.
Provide a Type 1 material certification that meets Article 106-3 of the Standard
Specifications for reinforcing casings and bars. Store steel reinforcement on blocking at least
12" above the ground and protect it at all times from damage; and when placing in the work
make sure it is free from dirt, dust, loose mill scale, loose rust, paint, oil or other foreign
materials.
For testing yield strength, define a "lot" as each truckload delivered and 2 samples and tests
are required per lot. Use steel casings with the minimum wall thickness shown in the plans
and outside diameters ranging from the minimum shown in the plans to 3" larger. Provide
casings meeting the tensile requirements of ASTM A252, Grade 3, except with an elongation
of at least 15% and yield strength of at least 50 ksi (343 MPa) unless noted otherwise in the
plans.
Use deformed steel bars that meet AASHTO M 275 or M31, Grade 60 or 75. Splice
reinforcing bars in accordance with Article 1070-9 of the Standard Specifications. Hollow
self-drilling bars shall meet ASTM A519 or A513 with minimum yield strengths of 100 ksi
and 87 ksi, respectively, and shall be oversized to account for up to 1/8-inch reduction in
diameter due to corrosion. Locate reinforcing casing joints at least 2 ft from bar splices.
Fabricate bar centralizers from schedule 40 PVC plastic pipe or tube, steel or other material
not detrimental to steel reinforcement (no wood). Size centralizers to position reinforcement
within 1" of drill hole centers and allow tremies to be inserted to ends of holes. Use
centralizers that do not interfere with grout placement or flow around reinforcement.

GT-2.2
W03293 PolkCounty
Use Class A concrete for cast-in-place concrete footing that meets Article 450-2 of the
Standard Specifications.
Provide micropile head assemblies consisting of nuts, washers and bearing plates. Use steel
bearing plates that meet ASTM A36 and steel washers and hex nuts recommended by the
Bar Manufacturer.
3.0 PRECONSTRUCTION REQUIREMENTS
Two submittals are required. These submittals include (1) micropile design and (2) micropile
installation and testing plan. Provide a PDF copy of each submittal. Submit the submittals
at least 30 days before starting micropile construction. Do not begin micropile construction
until the installation and testing plan is accepted.
A Design Engineer is required to design the micropiles. Submit documentation that the
Design Engineer is licensed by the State of North Carolina and has at least 5 years of
experience in designing micropiles for footing and in subsurface conditions similar to those
for this project. Documentation should include resumes, references, certifications, project
lists, experience descriptions and details, etc.
A. Micropile Footing Design Submittal
A conceptual micropile arrangement is shown in the plans. Review and verify existing site
and subsurface conditions and survey information before designing micropiles.
Design the micropile footing in accordance with the FHWA NHI-05-039 Micropile Design
and Construction, Chapter 6. Define "bond length" as the micropile center bar length below
the reinforcing casing tip elevation, the reinforcing casing tip elevation if a center bar does
not extend below the casing, or the micropile length in weathered rock or rock when only a
bar is used for the micropile. Perform a slope stability analysis using the soil parameters and
the assumed design failure plane shown in the plans. Determine the required bond length and
micropile reinforcement to provide a global factor of safety equal to 1.35. A bond length of
at least 10 ft into weathered rock or rock is required. Use a bond length factor of safety equal
to 2.0 for axial compression and uplift resistance. Evaluate the shear and bending moment
capacity of the cased and uncased sections in the unsupported length and casing joint portions
of the micropiles.
Design micropile footings with the minimum dimensions shown on the plans. Reinforce
micropile footings to resist the loading from the micropiles and slope instability.
When the micropile footing is utilized to provide bearing support of a retaining wall system,
design the micropiles and micropile footing to resist the vertical and horizontal retaining wall
loads.
When the micropile footing is used in conjunction with additional geotechnical systems such
as anchored soldier pile walls, permanent soil nail walls, and permanent soil nail shoring in
Shored MSE or GRS Retaining Walls, the benefit of all of the stabilization systems may be
combined to provide a minimum factor of safety of 1.35. The global stability benefit of a

GT-2.3
W03293 PolkCounty
MSE or GRS retaining wall shall not be considered.
Submit working drawings, slope stability analyses, and design calculations including
estimated unit ultimate capacities for acceptance in accordance with Article 105-2 of the
Standard Specifications. Include all dimensions, quantities, elevations and cross-sections
necessary to construct the micropile footing. Have piles designed, detailed and sealed by the
Design Engineer. When design changes occur due to load test results, varying site conditions
or other reasons, a revised design submittal is required.
B. Micropile Installation and Testing Plan Submittal
Provide detailed project specific information in the installation and testing plan that includes
the following:
1. List and sizes of proposed equipment including micropile drilling rigs and tools,
tremies and grouting equipment;
2. Sequence of micropile construction and step-by-step description of micropile
installation including details of casing installation, drilling methods and flushing;
3. List of reinforcement and casings including grades or yield strength and sizes;
4. Methods for placing reinforcement with procedures for supporting and positioning
the reinforcement including centralizers;
5. Procedures for placing grout including how the grout will be initially placed in drill
holes and acceptable ranges for grout pressures and volumes;
6. Equipment and procedures for monitoring and recording grout levels, pressures and
volumes with calibration certificates dated within 90 days of the submittal date;
7. Examples of construction records to be provided that meet Section 8.0 of this
provision;
8. Procedures for containment and disposal of drilling spoils, drill flush and waste
grout;
9. Approved packaged grout or grout mix design with acceptable ranges for flow and
density that meets Section 1003 of the Standard Specifications;
10. If load testing is required, load testing details, procedures and plan sealed by the
Design Engineer or Project Engineer for the Load Test Supplier with calibration
certificates dated within 90 days of the submittal date;
11. Load Test Supplier, when applicable, including Project Engineer; and
12. Other information shown in the plans or requested by the Engineer.
If alternate installation and testing procedures are proposed or necessary, a revised
installation and testing plan submittal may be required. If the work deviates from the
accepted submittal without prior approval, the Engineer may suspend micropile construction
until a revised plan is accepted.
C. Preconstruction Meeting
