The above represents the best information available to the Department and is included for the convenience of the bidder. The days required for conflict resolution should be considered in the bid as this information has also been factored into the timeline identified for the project when setting the completion date. The applicable portions of the Standard Specifications for Road and Bridge Construction shall apply.

Estimated duration of time provided above for the first conflicts identified will begin on the date of the executed contract regardless of the status of the utility relocations. The responsible agencies will be working toward resolving subsequent conflicts in conjunction with contractor activities in the number of days noted.

The estimated relocation duration must be part of the progress schedule submitted by the contractor. A utility kickoff meeting will be scheduled between the Department, the Department’s contractor, and the utility companies when necessary.

The contractor is responsible for contacting JULIE (or DIGGER within the City of Chicago) prior to any excavation work. Please note that IDOT electrical facilities are not part of the one-call locating services, such as JULIE or DIGGER.

If the contract requires the services of an electrical contractor, it is the contractor’s responsibility, at their own expense, to locate existing IDOT electrical facilities before commencing work. For contracts that do not require an electrical contractor, the contractor may request one free locate of IDOT electrical facilities by contacting the Department’s Electrical Maintenance Contractor.

Additional locate requests will be at the contractor’s expense.

The Department’s Electrical Maintenance Contractor must be notified at least 72 hours in advance of the work by calling 773-287-7600 or emailing dispatch@meade100.com to arrange for the locating of underground electrical facilities.

Please note, the marking of underground facilities does not absolve the contractor of their responsibility to repair or replace any facilities damaged during construction at their expense.

City of Aurora, Kane County

UTILITY LOCATIONS

The location of existing drainage structures, storm sewers, water mains, sanitary sewers, and any other public or private utility as shown on the plans is approximate and their exact location is to be determined in the field by the Contractor. This work shall be considered as included in the unit bid prices of the contract and no additional compensation will be allowed.

DAMAGE TO EXISTING UTILITIES

The contractor shall be responsible for the protection of all underground and surface utilities even if not shown on the plans. Any utility property damaged during construction shall be repaired.

STREET SIGN MAINTENANCE

The contractor shall be required to temporarily reset all signs that interfere with construction operations. All such signs must be maintained straight and clean for the duration of the temporary setting and must be re-erected at a temporary location in a workmanlike manner and be visible to the traffic for which it is intended. This work will not be paid for separately, but shall be included in the cost of Traffic Control and Protection, Standard 701501.

FAILURE TO COMPLETE PLANT CARE AND ESTABLISHMENT WORK ON TIME

Should the Contractor fail to complete the plant care and/or supplemental watering work as per the standard specifications or within 36 hours notification from the Engineer, or within such extended times as may have been allowed by the Department, the Contractor shall be liable to the Department in the amount of:

• $20.00 per sq yd sod/per day not as penalty but as liquidated damages, for each calendar day or a portion thereof of overrun in the contract time or such extended time as may have been allowed.

In fixing the damages as set out herein, the desire is to establish a mode of calculation for the work since the Department’s actual loss, in the event of delay, cannot be predetermined, would be difficult of ascertainment, and a matter of argument and unprofitable litigation. This said mode is an equitable rule for measurement of the Department’s actual loss and fairly takes into account the loss of the tree(s ) if the watering or plant care is delayed. The Department shall not be required to provide any actual loss in order to recover these liquidated damages provided herein, as said damages are very difficult to ascertain. Furthermore, no provision of this clause shall be construed as a penalty, as such is not the intention of the parties.

A calendar day is every day shown on the calendar and starts at 12:00 midnight and ends at the following 12:00 midnight, twenty-four hours later.

Should the Contractor fail to complete the work on a timely basis or within such extended times as may have been allowed by the Department, the Contractor shall be liable to the Department liquidated damages as outlined in the “Failure to Complete Plant Care and Establishment Work on Time” special provision.

In fixing the damages as set out herein, the desire is to establish a mode of calculation for the work since the Department’s actual loss, in the event of delay, cannot be predetermined, would be difficult of ascertainment, and a matter of argument and unprofitable litigation. This said mode is an equitable rule for measurement of the Department’s actual loss and fairly takes into account the loss of the trees if the watering is delayed. The Department shall not be required to provide any actual loss in order to recover these liquidated damages provided herein, as said damages are very difficult to ascertain. Furthermore, no provision of this clause shall be construed as a penalty, as such is not the intention of the parties.

A calendar day is every day shown on the calendar and starts at 12:00 midnight and ends at the following 12:00 midnight, twenty-four hours later.

Source of Water: The Contractor shall notify the Engineer of the source of water used and provide written certification that the water does not contain chemicals harmful to plant growth.

Rate of Application: The normal rates of application for watering are as follows. The Engineer will adjust these rates as needed depending upon weather conditions.

Sidewalk curb ramps shall be constructed according to current PROWAG requirements, the Highway Standards in the plans, and as directed by the Engineer. Additional side curb may be required at locations not explicitly shown on the Highway Standards or plans, such as on the back side of the sidewalk at the common square on perpendicular curb ramps (See Highway Standard 424001-12 PERPENDICULAR CURB RAMPS FOR SIDEWALKS). Per Article 424.12, all side curbs are measured for payment as sidewalk. This includes any side curb required at any location for a curb ramp, even if the side curb is not explicitly called out in a particular location on the Highway Standards.
