Subject: Summary of Construction Materials Testing Services
Modular Block Retaining Warts
Catawba County Detention Facility Addition
Newton, North Carolina
MACTEC Project No. 623405 -2987
Dear Mr. Sain:
As requested, MACTEC Engineering and Consulting Inc. (MACTEC) is presenting this report
summarizing our testing services performed during construction of the modular block retaining
walls at the Catawba County Detention Facility in August and September, 2005. Our scope of
work included inspection of shallow foundations and field compaction testing.
MACTFC performed testing of foundation excavations to verify the presence of soil bearing
materials suitable to provide the design soil bearing pressure. Prior to testing, auger borings were
incrementally advanced by manually twisting a sharpened steel auger into the soil. The bearing
elevations of the foundations were approved at the design elevations.
Field compaction tests were performed in general accordance with ASTM D 2937. The tests
performed met the required degree of compaction as specified in the project documents-
MACTEC appreciates the opportunity to provide our professional services to you on this project.
If you have any questions concerning the information in this report or if we can be of further
service, please contact us.
Sincerely,
MACTEC ENGINEERING 0W QpNSULT1NG, INC.
