About this file
Summary
This is a Micropile Foundation Design Package prepared for the Provo Water Reclamation Facility (PCWRF) Administration and Collections Buildings project located at 1685 South East Bay Boulevard in Provo, Utah. The design package, prepared by IGES, Inc. and Water Works Engineers, LLC, provides comprehensive technical specifications for micropile foundation systems supporting two new buildings. The project includes shop drawings and design calculations for micropiles of varying lengths (22, 37, 46, and 49 feet) utilizing R38N reinforcement bars, steel pipe casing with 9.625-inch outer diameter and 0.415-inch minimum wall thickness, and grout with minimum 28-day compressive strength of 4,000 PSI. The design incorporates soil investigation data from Cone Penetration Tests (CPTu) conducted by ConeTec, Inc. between July 10-16, 2026, at five sounding locations across the site. The package specifies construction details, connection requirements using 6-inch by 6-inch by 1-inch bearing plates, and comprehensive testing protocols including verification tests on two sacrificial micropiles to be loaded to at least 200 percent of design load in accordance with ASTM D3689 standards.
The geotechnical design is based on soil conditions identified through CPT analysis, revealing existing fill material to 20 feet depth with 38-degree friction angle, underlain by soft clay with 0-degree friction angle and 500 PSF cohesion. Design factors of safety applied include 2.0 for side and tip resistance in downward loading and 5.0 for side resistance in uplift conditions. Testing shall be performed only after grout achieves minimum 3-day compressive strength of 1,500 PSI, with design loads of 17 KIPS for the first verification pile and 33 KIPS for the second verification pile. Contractors are prohibited from testing micropile tensile loads exceeding 90 percent of reinforcement bar yield load (81 KIPS for R38N bars). All design work, specifications, and documentation remain the intellectual property of IGES, Inc., with alternative materials and construction methods requiring prior written approval from the design engineer.

BY THE CONTRACTOR TO OBTAIN THE REQUIRED BOREHOLE DIAMETER; HOWEVER, A 9.0 INCH DIAMETER DRILL BIT (MINIMUM) IS
RECOMMENDED.
3.3. STRUCTURAL ENGINEER SHOULD APPROVE THE CONNECTION BETWEEN THE PROPOSED FOOTING AND THE MICROPILE.
3.4. SOIL NAIL TENDONS MAY BE INJECTION BORED OR INSTALLED IN AN OPEN HOLE WITH PVC CENTRALIZERS SPACED NO MORE THAN 10 FT
O.C. BEGINNING NO MORE THAN 2 FEET FROM THE END OF THE TENDON. CENTRALIZERS SHALL BE SCHEDULE 40 PVC AND 1/2 INCH SMALLER IN OUTSIDE DIAMETER THAN THE DIAMETER OF THE BORE HOLE ALLOWING FREE GROUT FLOW.
4. CONNECTIONS
4.1. CONNECTIONS IN NEW FOOTINGS SHALL BE MADE USING A 6"x6"x1" BEARING PLATE, WASHERS, AND BAR NUTS AS SHOWN ON THE
DETAILS.
4.2. ALL CONNECTIONS SHALL BE EMBEDDED A MINIMUM OF 12 INCHES INTO THE PROPOSED FOOTING.
4.3. FOR NEW FOOTINGS, CONNECTIONS SHALL BE MADE BY TIGHTENING THE NUT ON THE PLATE UNTIL FIRM CONTACT IS MADE AND THE
PLATE IS NOT ALLOWED TO MOVE FREELY. FOOTING CONNECTIONS SHALL BE AS INDICATED ON SHEET 4.
5. TESTING
5.1. DESIGN LOAD SHALL BE DETERMINED BASED ON THE BONDED LENGTH AND THE VALUES IN THE ALLOWABLE LOAD ON SHEET 5.
5.2. TESTING SHALL BE PERFORMED IN ACCORDANCE WITH ASTM D3689, EXCEPT AS AMENDED HEREIN. IT IS RECOMMENDED THAT TESTING
SHOULD BE DELAYED UNTIL TEST PILE GROUT HAS ACHIEVED A MINIMUM 3-DAY COMPRESSIVE STRENGTH OF 1,500 PSI.
5.3. MICROPILES TESTED SHOULD HAVE A 5 FOOT MINIMUM TEMPORARY UNBONDED LENGTH.
5.4. VERIFICATION TESTS
5.4.1. VERIFICATION TESTS SHALL BE PERFORMED ON TWO ADDITIONAL SACRIFICIAL MICROPILES. THE SACRIFICIAL MICROPILES SHALL BE CONSTRUCTED USING THE SAME MEANS AND METHODS AS PRODUCTION MICROPILES, EXCEPT AS ALLOWED BY IGES. THE SACRIFICIAL MICROPILES SHALL BE TESTED TO AT LEAST 200 PERCENT OF DESIGN LOAD IN ACCORDANCE WITH THE TESTING
SCHEDULE ON SHEET 5.
5.4.2. TESTING SHOULD BE COMPLETED PRIOR TO CONSTRUCTION OF PRODUCTION MICROPILES. VERIFICATION PILES MAY NOT BE USED AS
PRODUCTION PILES.
5.4.3. THE MAXIMUM BONDED MICROPILE BAR LENGTH SHALL BE 30 FEET IN ADDITION TO AN UNBONDED LENGTH OF 5 FEET TO ENSURE
THE MAXIMUM BAR YIELD STRENGTH IS NOT EXCEEDED.
5.4.4. ADDITIONAL VERIFICATION TESTS MAY BE REQUIRED IF SUBSURFACE CONDITIONS VARY GREATLY, WHICH MAY NOT BE EVIDENT
UNTIL CONSTRUCTION.
5.4.5. BASED ON THE FINDINGS OF THE VERIFICATION TESTS, THE DESIGN OF THE MICROPILES SHALL BE ASSESSED; THE TOTAL LENGTH
MAY BE ADJUSTED, LONGER OR SHORTER, AS WARRANTED BY THE TEST RESULTS.
5.5. FOR TENSILE LOADING, MAXIMUM TEST LOAD CANNOT EXCEED 90 PERCENT OF THE REINFORCEMENT BAR YIELD LOAD (E.G., DO NOT
EXCEED 81 KIPS FOR A R38N BAR).
5.6. MICROPILES MAY BE TESTED IN EITHER COMPRESSION OR TENSION, AT THE CONTRACTOR'S DISCRETION.

Cone Penetration Test (CPTu)
Depth reference Depths are referenced to the existing ground surface at the time of each test.
Tip and sleeve data offset 0.1 Meters. This has been accounted for in the CPT data files.
Additional Comments None
Calculated Geotechnical Parameters
Additional information
The Normalized Soil Behavior Type Chart based on Qtn (SBT Qtn) (Robertson, 2009) was used to classify the soil for this project. A detailed set of calculated CPTu parameters have been generated and are provided in Excel format files in the release folder. The CPTu parameter calculations are based on values of corrected tip resistance (qt) sleeve friction (fs) and pore pressure (u2).
Effective stresses are calculated based on unit weights that have been assigned to the individual soil behavior type zones and the assumed equilibrium pore pressure profile.
Soils were classified as either drained or undrained based on the Qtn Normalized Soil Behavior Type Chart (Robertson, 2009). Calculations for both drained and undrained parameters were included for materials that classified as silt mixtures (zone 4).

Totals 5 Soundings 353.34 ft
1. The assumed phreatic surface was based off the shallowest pore pressure dissipation tests performed within or nearest the sounding. Hydrostatic conditions were assumed for the calculated parameters.
2. The coordinates were collected using consumer grade GPS equipment with an accuracy of ±50 feet. EPSG number: 4326 (WGS84 / LatLong).
3. Elevations are referenced to the ground surface and were acquired from Google Earth Elevation for the recorded coordinates.
4. The assumed phreatic surface is based on the second dissipation test performed at this location. The data from the second dissipation compares favorably with historic data that was collected at the same site.
5. The phreatic surface is assumed to be deeper than the explored depth.

Methodology Statements
Cone penetration tests (CPTu) are conducted using an integrated electronic piezocone penetrometer and data acquisition system manufactured by Adara Systems Ltd., a subsidiary of ConeTec.
ConeTec’s piezocone penetrometers are compression type designs in which the tip and friction sleeve load cells are independent and have separate load capacities. The piezocones use strain gauged load cells for tip and sleeve friction and a strain gauged diaphragm type transducer for recording pore pressure.
