Right-Of-Way
Excavations
ROW Permit Application
The "Standard Specifications for Road and Bridge Construction" (SSRB)
prepared by the Illinois Department of Transportation and the
following special provisions govern the procedures and the
construction practices for street excavations.
RESPONSIBILITY
No private contractor shall perform any right-of-way excavation
without a permit from the Department of Public Works. In the event
the permit or any of the permit specifications are not clear, the
Public Works office should be contacted for clarification. The
Applicant shall assume all liability for any damage to existing
utilities in, along or upon the City right-of-way. It is the
Applicant’s responsibility to have all utilities located prior to
commencing work. The permit holder shall be solely responsible for
any accident/damage resulting from the Applicant’s work or the
repair thereof.
TRAFFIC SAFETY
All construction operations shall be conducted in a manner to
insure minimum hindrance to traffic using the roadway.
Unless specifically allowed by the City, no street detours, lane
closures or shoulder usages are authorized.
The applicant shall furnish, erect, maintain and remove all
barricades, lights, etc., as well as provide, when necessary,
flagpersons for the protection and safe accommodation of traffic on
the roadway affected by this work.
The traffic controls utilized shall be in accordance with the
State of Illinois Manual of Uniform Traffic Control Devices and the
appropriate Illinois Department of Transportation State Standard
Specifications, which are minimum requirements. The Director of
Engineering may require additional traffic control devices, as he
deems necessary.
The pavement or sidewalk shall not be blocked by loading,
backfilling or hauling equipment. When excavations are made in the
pavement, not more than one lane of pavement shall be closed to
traffic.
In cleaning operations, the Applicant shall take care not to
deposit dirt or foreign material in pavement or gutters or to block
or plug drainage catch basins. If such care is not taken, the
Applicant will be back-charged for cleaning, sweeping, etc. at the
direction of the Public Works Director.
The Applicant shall properly furnish, erect, maintain and remove
all barricades, lights, etc., for the safe handling of pedestrian
and/or vehicle traffic for all openings made within the permit area
during all work performed by him. Such traffic control and safety
devises shall meet the approval of the Director of Engineering or
Director of Public Works.
PAVEMENT EXCAVATION
Excavations made in the pavement shall be completed and
backfilled in one day unless (a) steel plates adequately anchored
are placed over the excavation or, (b) a properly controlled traffic
diversion is authorized by the Public Works Director.
All edges of pavement openings shall be cut with a concrete saw
to a depth of not less than two (2) inches or to full depth of
bituminous concrete replacement, whichever is greater. Openings in
P.C. Concrete Pavements shall be made at existing construction
joints wherever possible.
If the P.C. Concrete base of a bituminous resurfaced pavement is
not shattered or cracked beyond the limits of the pavement opening,
the edges may be trimmed with a pneumatic hammer using a chisel or
nail point. All deteriorated concrete or concrete cracked during
permit work shall be removed to point where solid concrete exists.
Further pavement saw cutting may be necessary in this case to
prevent damage to pavement areas beyond the proposed opening.
The Applicant shall haul away and properly dispose of all
excavated material. Walls of trenches shall be adequately braced to
prevent cave-ins. Such cave-ins, should they occur, will require
additional pavement removal to a point where undisturbed sub-base
exists. Compliance with all OSHA regulations and procedures shall be
the sole responsibility of the Contractor.
Tunneling shall be defined as the use of any means other than an
auger to remove soil or other material from underneath any existing
pavement curb, or sidewalk, and shall not be permitted. Auguring
shall be permitted provided that the diameter of the augured opening
shall not be more than two inches greater than the diameter of the
pipe to be placed therein.
No construction materials of any kind shall be stored on the
Public Right-of-Way.
Whenever a pavement opening in a P.C. Concrete pavement is made
less than 3 ft. from a pavement edge, construction joint, crack,
etc., the pavement opening will be enlarged to meet the edge, joint
or crack so that the entire area will be repaired as one patch.
BACKFILL
Backfill over conduit may be made with fine aggregate (FA-1, 2 or
3), or coarse aggregate (CA-13 or CA-7), to a point 6 inches above
the conduit. All backfill material shall be placed in layers not to
exceed 8 inches loose and be mechanically compacted in place. The
permittee shall notify the City of Des Plaines Public Works
Department 24 hours in advance of backfilling. No backfilling shall
be done except under the auspices of the Director of Public Works,
or his designated representative.
The remaining backfill material to the surface elevation shall be
controlled low strength material (CLSM), Mix 1, otherwise known as
flowable fill. Mix 1 must meet the following requirements:
| Compressive |
28 days |
90 days |
| Strength |
30-80 psi |
100 psi ma. |
| Slump |
10-12 inches |
|
| Air |
1-30% |
|
PAVEMENT REPLACEMENT
Permanent flexible pavement replacement will be made by the City.
The permittee shall make payment at the rate of $55.00 per linear
foot for pavement replacement at the time of making application. The
linear footage shall be estimated for the application by assuming
the pavement dimensions being 2 ft. larger (1 ft. around the
perimeter) than the projected size of excavation. The Applicant will
be billed for any overages of the actual replacement over the
quantity in the permit. Failure to pay the additional cost within 30
days of billing shall result in the Applicant being denied from
future work on City property for a 5-year period.
Permanent rigid pavement replacement shall be made by the
Applicant in accordance with the applicable portions of Section 304
of the Standard Specifications of the Illinois Department of
Transportation except that the concrete mixture shall utilize either
a high-early strength Portland cement or a 7-bag mix of regular
Portland cement. Temporary flexible pavement replacement shall be
made by the applicant to bring excavation to surface grade.
Replacement of full width openings shall be done one-half at a
time allowing the first half to adequately cure prior to placing the
remaining half.
SIDEWALK, CURB & GUTTER REMOVAL AND REPLACEMENT
Openings in P.C. Concrete sidewalk, curb and gutter shall be made
along existing construction joints unless authorized by the Director
of Engineering. All edges of the opening shall be cut with a
concrete saw to a minimum one-half of the depth of the existing
structure prior to breakout with pneumatic hammer.
Backfill material beneath P.C. Concrete sidewalk, curb and gutter
to be replaced shall be crushed CA-6 placed in an 8 inch layers
(loose) and mechanically compacted in place.
Three pieces of ½" epoxy coated rebar shall be used for sidewalk
over trench.
The Applicant has the responsibility of replacing P.C. Concrete
sidewalk, curb and gutter in accordance with City and IDOT SSRB
specifications. The following minimum concrete specifications are
required:
| Cement |
6 bags of Type I per cu. yd. |
| Aggregate |
1.5 inch maximum |
| Slump |
4 inch maximum |
| Air-Entrainment |
5% to 8% |
| Curing Time |
72 hours with securely anchored polyethylene |
| Strength |
3500 psi in 14 days |
| Sidewalk Thickness |
5" minimum, 6" minimum for portions across driveways |
| Curb & Gutter Flag Thickness |
10" |
The Applicant and/or his Contractor shall be responsible for
adequately protecting the new concrete and for proper and safe
pedestrian and/or vehicle traffic control.
LANDSCAPING, SEEDING AND SODDING
All excavations made in sodded parkways shall be replaced with
sod surface. In other areas the top four inches of excavation shall
be replaced with topsoil and the entire disturbed area seeded. The
Applicant shall be responsible until the area is established. The
Applicant shall not trim, cut or in any way disturb any trees or
shrubbery along the parkway without the approval of the Director of
Public Works or his duly authorized representative.
