Reference: Soil Density Testing
Lots 31 and 32 Wingfoot Drive
St. James Plantation
Southport, North Carolina
RFTS Job No. 734-13
Dear Mr. Brambell:
RFTS is pleased to provide testing services during the soils repair work on Lots 31 and 32
Wingfoot Drive located near Southport, North Carolina.
As requested, our personnel visited the site during the period of February 27 through March 13,
2014 to perform compaction testing of fill soils being placed at the site. These tests were
performed in general accordance with ASTM D-1556 "Standard Test Method for Density and
Unit Weight of Soil in-place by the Sand-Cone Method". The percent compaction of the test
during these visits ranged from 97.3 to 100 of the standard Proctor maximum dry density.
Additional information concerned with these test are presented in the "Sand Cone Density Test
Report" included with this cover letter.
A sample of the fill soil had been previously collected from the site and was delivered to our
laboratory in Carolina Beach, NC. The sample(s) was tested in general accordance with ASTM
D-698 "Standards for Test Method for Laboratory Compaction Characteristics of Soil Using
Standard Effort." The standard Proctor test report is also included with this cover letter.
Based on the result of our density testing, these lots are consider suitable for residential construction
of single family homes that can be supported on shallow concrete footings designed for a maximum
soil contact pressure of 2000 pounds per square foot (psf) bearing in the upper 12 to 24 inches, below
the ground surface. However, we do recommend soil bearing capacity testing (such as dynamic cone
penetrometer testing) of the foundation supporting soils be conducted once the layouts of the
foundations have been determined.
Please find attached a sketch showing the approximate test locations. If you have any questions after
reviewing this letter, please do not hesitate to contact us at your convenience,
Sincerely,
T P L C
