RE: Geotechnical Engineering Evaluation
Traffic Signal Improvements
Daniel Webster Highway and Graham Drive
Nashua, New Hampshire Project No. 16.186.NH
Dear Mr. Osorio:
This report presents the results of a geotechnical engineering evaluation completed for proposed
traffic signal mast arm to be located at the intersection of Daniel Webster Highway and Graham
Drive in Nashua, New Hampshire. This evaluation was completed in accordance with our
proposal dated June 7, 2016 (Ref. File 252-16 Revision 1), and consisted of:
1. Performing a subsurface exploration program consisting of one (1) test boring; the test
boring drilled at the location of the proposed support structure for the traffic signal mast
arm;
2. Evaluation of the subsurface conditions and performing geotechnical engineering
analyses to develop foundation design recommendations for the proposed traffic signal
mast arm; and
3. Summarizing the exploration program and engineering analyses in this Project
Geotechnical Report.
Presented herein is a description of the proposed project, subsurface conditions encountered, and
the geotechnical engineering implications of subsurface conditions on recommended design
specification for the supporting structure of the traffic signal mast arm. The contents of this
report are subject to the limitations presented as Attachment A.
SITE AND PROJECT DESCRIPTION
The proposed traffic signal mast arm has been planned on the east side of Daniel Webster
Highway, at the intersection of Daniel Webster Highway and Graham Drive in Nashua, New
Hampshire.
For this evaluation, we reviewed the following documents:
