Re: Hunters Pass Estates Residential Development

Albertville, Minnesota
Dear Mr. Froelich:
Project AL-05-00769
The attached report summarizes the excavation observations and compaction testing completed on the
Hunters Pass residential development in Albertville, Minnesota.
The purpose of the excavation observations was to assist in evaluating the suitability of the soils
encountered in the excavation bottoms for fill and building support. The purpose of the compaction
testing was to evaluate the effectiveness of the compaction procedures being used by the excavating
contractor and to determine if the densities obtained in the field met the minimum project specifications.
Available Information
We were provided with a grading, drainage and erosion control plan prepared by Meyer-Rohlin, Inc.
(Meyer-Rohlin) dated April 7, 2005, last revised June 22, 2005.
Braun Intertec performed a geotechnical evaluation for this site. The report, dated March 30, 2005,
Braun Intertec project number AL-05-00769A, was referenced to verify subsurface soils conditions and
recommendations.
Proposed Construction
The development will consist of constructing single-family home building pads with associated roadways
and utilities. The grading for this phase of the development includes:
Lots through4, Block 1, First Addition
Lots 1 through 19, Block 2, First Addition
Lots 1 through 9, Block 3, First Addition
Lots 1 through 10, Block 4, First Addition
Lot 1, Block 5, First Addition
Lots 1 through 22, Block 6, First Addition
Lots 1 through 6, Block 1, Second Addition
Lots 1 and 2, Block 2, Second Addition
Lots I through 4, Block 3, Second Addition
Providing engineering and environmental solutions since 1957

Lots 1 through 5, Block 4, Second Addition
Lots lthrough 9, Block 5, Second Addition
Lots 1 through 4, Block 6, Second Addition
The single-family homes will have full -depth basements with concrete or masonry bearing walls to first
floor level or adjacent outside grade, with wood -frame construction above grade. Typical spread footing
foundation systems will be used for building support. We assume the footing pressures will not exceed a
maximum net allowable soil bearing pressure of 2,000 pounds per square foot (psf).
Some of the building pads required compacted fill to be placed to attain building grades and some of the
building pads will need to be excavated (or cut) into native soils to reach building grades.
Cut -to -Grade Lots
Cut -to -grade lots require excavation into natural soils to establish footing grade. During excavation for
the footings on these lots, we recommend that footing subgrades be observed by the builder, excavating
contractor and the city inspector. If questionable or poor soil conditions are encountered, we recommend
that a geotechnical engineer perform observations to further evaluate the soil conditions. These "cut" lots
include:
Lots 6, and 9 through 18, Block 2, First Addition
Lots 7 through 10, Block 4, First Addition
Other lots required minimal amounts of fill and may be constructed with footings on natural soils. These
lots are not listed here but can be determined by reviewing the 79g tabulation.
Excavation Observations
Lots requiring compacted fill were observed after site stripping of topsoil and removal of any deeper,
unsuitable soils.
The excavation observations were performed by an engineering assistant during the site grading from
July 7 to August 3, 2005. During the site grading, Dennis Fehn Gravel and Excavating, Inc. (Fehn)
typically stripped surficial topsoil and vegetation from the building pads and roadways with bulldozers
and scrapers. When needed, a backhoe was used to remove unsuitable material.
Our excavation bottom elevations and oversize measurements were referenced from offset stakes
provided by Fehn based on the staking provided by Meyer-Rohlin. The exact location of the building
pads is therefore the responsibility of the excavating contractor and surveyor
Visual observations were performed to aid in evaluating the suitability of the soils encountered in the
excavation bottoms. In addition to observing the excavation bottom and sidewall soils, we performed
random hand auger borings up to 3 feet deep. The soils exposed and retrieved were classified in general
accordance with American Society for Testing and Materials (ASTM) D 2488 procedures. Estimates
1 were made of the soil strength properties by judging the force required to advance the auger.

Soils encountered in the excavation bottoms typically consisted of lean clay and silty sand. Based on the
effort required to advance the hand auger, the granular soils were judged to be medium dense and the clay
soils were judged to be medium.
The excavation to remove the unsuitable material was also extended at least 1 foot laterally for each foot
of fill required below proposed footing grades (1:1 oversizing). The attached sketch and 79g tabulation
outlines the approximate excavation bottoms and oversize measurements.
Engineered Fill
Engineered fill placed to establish building and pavement grades consisted mainly of lean clay taken from
other portions of the site. During the site grading, fill was typically placed in 6- to 12-inch thick lifts with
scrapers, spread by bulldozers and then compacted using a large sheepsfoot compactor.
Compaction Tests
A total of 76 compaction tests were performed in the engineered fill placed in building areas during the
site grading. The locations on the compaction reports represent the specific area and elevation noted.
The minimum density requirement of the engineered fill placed in building pads was 95 percent of
standard Proctor density (ASTM D 698). In areas requiring more than 10 feet of fill, the minimum
requirement was increased to 98 percent.
All compaction tests performed in the building areas met or exceeded the minimum density requirement.
Summary
Based on the results of our borings, excavation observations and hand auger probes, it is our opinion the
soils encountered in the observed excavation bottoms are suitable for fill and building support.
IBased on the staking provided by others, it appears the observed excavations were adequately oversized.
Based on the results of our compaction tests, it is our opinion the engineered fill placed in the building
pads is suitable for house support.
As the lots are constructed on, we recommend that the footing subgrades be observed by the builder,
contractor, and the city inspector. If questionable or poor soil conditions are encountered, we recommend
that a geotechmcal engineer perform observations to further evaluate the soil conditions.
General Remarks
The graded building pad locations are shown on the grading plan prepared by Meyer-Rohlin, Inc. dated
April 7, 2005, last revised June 22, 2005. The area corrected for a proposed building is a specific area
shown on this plan. The exact locations and preparation of the graded building pads is the responsibility
of the excavating contractor.

We caution any builder who builds on this project to carefully evaluate the location of the proposed
building with respect to the corrected building pad. A building situated on a lot that is not located within
the corrected pad location may not be founded on suitable soil or have adequate oversizing for lateral
support of the fill or foundation loads. If a builder is unsure as to the location of the corrected pad, or if
they are suspicious as to the suitability of the foundation soils, it is recommended we be contacted to
assist the builder in locating the building pad and suitable foundation soils.
No established national standard exists for excavation observations. We have used the methods and
procedures described in this report to evaluate the exposed soils. Other firms may use different
procedures to evaluate bottoms of excavations.
Services performed by Braun Intertec personnel for this project have been conducted with that level of
care and skill ordinarily exercised by members of the profession currently practicing in this area under
similar budget and time restraints. No warranty, expressed or implied, is made.
Thank you for using Braun Intertec. If you have any questions or require additional information, please
call Josh Kirk at 952.995.2222 or Henry Vloo at 952.995.2238.
Sincerely,
BRAUN INTERTEC CORPORATION
