Sec. 9.
(a) In a
				common open trench, the ITS conduit, colored orange, blue and green, shall be
				placed first at the bottom of the trench. The limited access highway conduit
				shall be colored red, black, white, and grey and shall be placed above the ITS
				conduit. If there is space available in the trench, an operator may place
				conduit in the trench and the conduit shall be terracotta or purple
				colored.
(b) Conduit may be
				trenched or plowed at the operator's discretion and as allowed by the site
				conditions.
(c) All flexible
				roadside delineators disturbed during trenching operations shall be restored or
				replaced at no additional cost to the department.
(d) The conduit type, number and size shall
				be shown on the permit plans.
(e)
				Hand trenching is in areas where sensitive existing crossing utilities or
				broadband have been identified and will likely require positive identification
				of the existing utility or broadband prior to trenching above or below the
				existing utility line or where surface features such as riprap would inhibit
				trenching. The method of positive identification of the existing utility line
				shall be at the discretion of the operator and shall be accomplished with no
				additional compensation. Any material that is removed to accomplish hand
				trenching shall be restored or replaced in kind by the operator without
				additional compensation.
(f)
				Conduit may be installed by directional drilling at locations specified as hand
				trenched or offset trench on the permit plans with no additional
				compensation.
(g) Offset trench is
				in areas where the trench is located behind obstructions. This type of
				trenching shall utilize a long reach hydraulic driven trenching machine to
				reach over and beyond the obstruction to complete the trench.
(h) Trenches, bedding and backfill shall be
				in accordance with the INDOT Specifications as outlined in this subdivision
[subsection]
:
(1) Trenches
				will be cut with vertical faces where soil and depth conditions allow. The
				width of a trench will be the minimum necessary to accomplish the installation.
				Shoring shall be used when necessary, in accordance with Occupation Safety and
				Health Administration requirements.
(2) Bedding will be provided to a depth of
				six (6) inches or fifty percent (50%) of the nominal diameter of the pipe,
				duct, or duct bank, whichever is less. Bedding shall not be required for pipes,
				ducts or duct banks encased in concrete or flowable fill. The bottom of the
				trench shall be prepared to provide the pipe, duct or duct bank with uniform
				bedding support throughout the length of the installation.
(3) Backfill shall be provided in accordance
				with the INDOT Standard Specifications, Section 715.09* as effective September
				1, 2019.
