Re: Addendum to Geotechnical Engineering Report
Proposed Hammond Street Townhomes
Coppell, Texas
Rone Project No. 14-19365
Dear Mr. Rose:
Rone Engineering Services, Ltd. (Rone) has been requested to provide additional
recommendations regarding the subgrade preparation for the 10-foot wide and 700-foot long
Alley pavement for the referenced project. This request was made by the client in a telephone
conversation with Mark Gray. This letter presents our recommendations and should be
considered an addendum to Rone’s Geotechnical Engineering Report 14-19365 dated
September 5, 2014. This letter should not be considered separately from the geotechnical
report.
In our original report, we recommended that pavement subgrade be treated to a depth of 6
inches with lime. Provided the pavement and surrounding areas are well drained, six inches of
flex base can be used and lime treatment omitted.
Any other comments and recommendations contained in the original geotechnical report remain
unchanged. Thank you for the opportunity to provide services to you for this project. Please call
if you have any questions regarding this letter.
Respectfully submitted,
A. Reza Savabi, P.E. Xuhui Chang, P.E.
