PART 3 — EXECUTION
3.01 INSTALLATION:
A. Work shall not be started until all materials and equipment necessary for their
construction are either on the site of the work or satisfactorily available for
immediate use as required.
B. _ The sheeting shall be securely and satisfactorily braced to withstand all pressures to
which it may be subjected and be sufficiently tight to minimize lowering of the
groundwater level outside the excavation.
C. No sheeting may be left so as to create a possible hazard to safety of the public or a
hindrance to traffic of any kind.
D. If boulders or very dense soils are encountered, making it impractical to drive a
section to the desired depth, the section shall be cut off.
E. The sheeting shall be left in place where indicated on the drawings or ordered by the
Engineer in writing. At all other locations, the sheeting may be left in place or
salvaged at the option of the Engineer. Steel sheeting permanently left in place shall
be cut off at a depth of not less than two feet below finish grade unless otherwise
directed.
F. All cut-off will become the property of the Contractor and shall be removed by him
from the site.
G. Sole responsibility for the satisfactory construction and maintenance of the
excavation support system, complete in place, shall rest with the Contractor. Any
work done, including incidental construction, which is not acceptable for the
intended purpose shall be either repaired or removed and reconstructed by the
Contractor at his expense.
H. The Contractor shall be solely responsible for repairing all damage associated with
installation, performance, and removal of the excavation support system.
