Re: Construction Observation and Testing – Submittal No. 1
903 Buckingham Street – Pavement Improvements
Fort Collins, Colorado
EEC Project No. 1174111
Mr. Giuliano:
As requested, during the period of October 23 through November 4, 2017, Earth Engineering
Consultants, LLC (EEC) personnel provided construction observation and testing services for the
on-going construction improvements associated with the 903 Buckingham Street pavement
improvements project in Fort Collins, Colorado. The services provided during the referenced
period were on a part-time/on-call basis and included observations, field density testing of road
subgrade materials at locations as described herein for the referenced project. The results of the
observation and testing services completed by EEC personnel during the referenced period are
included with this report.
Field Density Testing Services
During the referenced period, EEC personnel performed field density tests on road subgrade
materials that had been prepared/placed and compacted prior to and/or during our various site
visits. The field density tests were completed at random locations within the areas tested, and
were performed in general accordance with ASTM Specification D6938. The field density test
results and approximate locations of each test completed during the referenced period are shown
on the attached summary sheet. The field density test results conformed to typical project
specific compaction requirements of at least 95% of standard Proctor maximum dry density
(ASTM D698), and were generally within ±2% of optimum moisture content.
