TxDOT - Dallas District Utility Specification
Construction of Highway Crossing bore
1. GENERAL - WATER JETTING OR JACKING WILL NOT BE PERMITTED All paved streets which are maintained by
TxDOT Must be bored & encased unless it is specifically stated on the permit that an exception for open cutting and /or
no encasement is granted.
At no time shall the boring operation interfere with the traveling public. The safety of the traveling public and maintaining the
integrity of the roadway is the primary concern.
2. BORE PIT LOCATIONS - No excavations for bore pits will be allowed to be any closer to the edge of the pavement (travel
lane) than as outlined in the "TRENCH EXCAVATIONS AND PIT LOCATION" specification. If the required clear zoned
distance is closer than outlined in the above mentioned specification, then appropriate traffic control devices such as
barricades, signs, barrel mounted guard fence and /or concrete traffic barriers will be required as deemed necessary by
the TxDOT inspector.
No excavated material will be stored closer to the traveled way than the bore pit. All pits and trenches shall be backfilled
immediately after the encasement and carrier pipes have been installed, Upon completion of the backfill, all excess
material will be removed from the right of way.
3. METHOD OF INSTALLATION - Crossings are to be installed by the AUGER or "DRY" BORE method and shall be
accomplished by use of a laser sighted bore machine or a bore machine requiring a pilot hole. The pilot hole will serve
as the centerline of the large diameter hole to be bored. The user of water or fluids in the boring operation will only be
allowed for lubricating the cutting head.
The boring operation shall be performed from the low or downstream end. Lateral or vertical variation of the encasement
pipe from the proposed line and grade will be permitted only to the extent of one (1) inch in ten (10) feet, provided that
such a variation shall be regular and only in one direction.
The encasement pipe shall be approximately the same diameter as the bore hole. Over cutting in excess of one (1) inch
shall be remedied by pressure grouting the entire length of the installation with a mixture consisting of two (2) sacks of
cement per yard of sand.
4. OPTIONAL WET BORE - The utility or contractor may request installation by the Slurry or "Wet" bore method. The approval
to wet bore is granted by the Area Engineer or his designated representative on an individual permit basis. It the area
office allows wet bores in their designated area, approval will be based on bore size and soil conditions. Wet bores
should be restricted to areas of rock or other suitable material which will prevent the sides of the bore hole from "caving
in ". A geotechnical report may be required prior to approval. In no instance will wet bores be allowed to exceed eighteen
(18) inches in diameter.
The amount of water used for creating the slurry will be such that little or no runoff is encountered. If, in the opinion of the
TxDOT inspector, at any time during the boring operation inadequate conditions are encountered for performing the wet
bore, the process will be stopped and the bore will be completed by Auger bore.
The slurry material removed from the bore may not be used in the backfilling of the bore pit.

the traveling public.
Topsoil shall be kept separate from other excavation material, and be replaced in accordance with "BACKAI -LING"
specification.
All pits and trenches shall be kept free from standing water. if trenches and /or bore pits are left open for extended periods of
time without a continuous progression of work, the utility will be required to backfill the trench and /or bore pits. Any other
pit will not be left open for more than a forty eight (43) hour period.
In all excavations where sloughing is likely to occur, shoring will be utilized to prevent damage to the highway structure(s).
The utility agency or contractor shall be responsible for maintaining trench excavation protections as required by
provisions of Part 1926, Subpart P - Excavations, Trenching and Shoring of OSHA Standards.
2. TRENCHING - Longitudinal installations must be placed as near a uniform alignment to the right of way line as possible.
Trenching machine or backhoe may be used. A backhoe will be required if a uniform alignment can't be maintained by
use of a trenching machine.
3. SAFETY CLEAR ZONE DISTANCES - Minimum clear zone distances required for trench excavations and bore pit locations
are as follows:
For UNCURBED Highway
A. Thirty (30) ft. from the edge of pavement (traveled lane) of high -speed (more than 40 mph), high volume
(more than 750 vehicles per day) highways.
B. Sixteen (16) ft* from edge of pavement of high - speed, low volume (less than 750 vehicles per day) highways.

Backfill St- ecificatiens
1. GENERAL - As soon as practical, all portions of the excavation shall be backfilled. Trenches and pits shall be backfilled with
the material obtained from the excavation or from other sources. Backfill material will be free from stones of Such size
as to interfere with compactions; free from large lumps which will not break down readily under compaction, and free
from frozen lumps, wood or other extraneous material. The TxDOT inspector may reject any material containing more
than twenty (20) percent by weight of material retained on a three (3) inch sieve.
The portion of top soil removed from the original excavation shall be replaced, as nearly as feasible, in its original
position.
2. DEPTH OF LIFTS - The portion of backfill below the top of pipe shall be placed in uniform layers not to exceed eight (8)
inches in depth (loose measurement). Backfill above the top of the pipe shall be placed in layers not to exceed ten (10)
inches in depth (loose measurement). If the backfill is to support a portion of roadway or embankment, then the material
will be placed in uniform layers not to exceed eight (8) inches in depth (loose measurement).
3. PROCEDURE FOR COMPACTION - Each layer of backfill material, if dry, shall be wetted uniformly to the moisture content
required to obtain a density comparable with the adjacent undisturbed soil and shall be compacted to that density by
means of mechanical tampers or rammers. The use of rolling equipment of the type generally used in compacting
embankments will be permitted on portions that are accessible to such equipment. Water jetting or ponding will not be
permitted.
Special care shall be taken to ensure thorough compaction of material placed under the haunches of the pipe.
Cohesionless materials, such as sand, may be used for general backfilling purposes. Compaction of collesionless materials
shall be done with vibratory equipment.
4. RESTORATION OF RIGHT OF WAY - Prompt replacement of sod, removal of debris, and any other restoration necessary to
restore the right of way to a condition equal to that which existed prior to the utility installation will be required. In areas
of erosion, the use of stabilized backfill may be required. Should settlement or erosion occur within six (6) months of the
utility installation, the utility agency will be required to reshape, reseed, and /or resod the area.
