1.109 of this code.
(2) A
trench safety system shall be provided in any excavation which exceeds
a depth of five feet (5') if any person is required or allowed to
enter said excavation for any reason or may be otherwise exposed to
cave-ins. A trench safety system shall also be required in an excavation
of less than five feet (5') if soil instability or a danger of ground
movement exists. The types of trench safety systems currently allowed
include shoring, bracing, solid shoring, sloping of the ground and
trench shields.

material storage;
(5) Details
of the trench safety system, including methods and equipment for excavation,
construction, installation and worker safety;
(6) For
excavations having sloped trenched sides, soil testing laboratory
reports determining the maximum angle of repose. For testing purposes,
core samples are required no less than each seven hundred (700) linear
feet of trench length; and
(7) Any
other OSHA Standards pertinent to proper completion of said project.
(b) Plans,
specifications, and reports submitted for permit shall bear the name,
seal, and registration number of an engineer and contain the following
certificate:
“I hereby certify that these plans and accompanying specifications
or these engineering works were prepared by me, or under my direct
supervision, in accordance with OSHA and City of Panhandle Trench
Excavation And Construction Safety Standards and Requirements.”

(c) Fees for each trench excavation permit as set out in Section
3.907 shall be paid prior to the initiation of work.
(d) The
bid documents and the contract authorizing the work for which a trench
excavation permit is required shall include, in addition to the plans
and specifications for the trench safety system, a separate pay item

(1993 Code of Ordinances, Appendix 3)
(a) Materials
used for sheeting, sheet piling, cribbing, bracing, shoring, and underpinning
shall be in good serviceable condition, and timers shall be sound,
free from large or loose knots, and of proper dimensions, as called
for in the OSHA Construction Standards, Subpart P, Table P-2, which
is on file with the city and is made part hereof. Defective materials
or equipment may not be used and shall immediately be removed from
the job site.
(b) Steel
trench shields shall be constructed of steel plate welded or bolted
to a rigid steel framework and include the following minimum protective
measures:
(1) Trench
shields shall be constructed in a manner that provides protection
at a minimum equal to sheeting or shoring required for trench safety
construction;
(2) Adjustable
jacks that meet or exceed the rigidity requirements of OSHA Standards
and this article may be used;
(3) An
access ladder shall be provided at the midpoint or center of the trench
shield for ingress-egress;

or wheels may be installed or incorporated under the trench shield
side walls for ease of movement;
