DESCRIPTION OF PROJECT

This work consists primarily of the removal of existing pavement surfaces, the placement of asphalt overlay at various locations as shown on the plans, the removal and replacement of curb and gutter and the removal and replacement of sidewalk and sidewalk ramps. The work shall include all labor, materials, tools, and equipment necessary for the proper execution and completion of the work as shown in the plans and as specified. It shall also include all work not specifically mentioned, but which is reasonably and properly inferable and necessary for the completion of the work.

Plan sheets provided are to be used as a guide. Work to be performed on the City Streets will be marked with white or pink paint by a representative from the City.

The paint marks and/or directives given by the Engineer will supersede information provided on plan sheets contained in this contract.

All locations are subject to change within the construction area, and the Contractor shall not proceed at any location without first receiving permission from the Engineer. Locations may be modified, added, or subtracted, throughout the contract period.

ADDITION OR DELETION OF STREETS & QUANTITIES

The City reserves the right to add or remove streets from the list and increase, decrease, add, or delete quantities and pay items in this contract. Any such additions may include an extension of time to the Contractor to complete the work.

PARTIAL PAYMENTS

Add the following after the first paragraph of Article 109.07(a) of the Standard

Specifications:

“The City will deduct from the amount so determined for the first 50 percent of the completed work a sum of ten percent to be retained until after the completion of the entire work to the satisfaction of the Engineer. After 50 percent or more of the work is completed, the Engineer may, at his/her discretion, certify the remaining partial payments with a reduction in retention for the partial payments or without any further retention, provided that satisfactory progress is being made, and provided that the amount retained is not less than five percent of the total adjusted contract price.

When the principal items of the work have been satisfactorily completed, a semi-final estimate may be made with the consent of the surety. Payment to the Contractor under such an estimate shall not exceed 90 percent of the amount retained after making partial payments, but in no event shall the amount retained after making the semi-final payment be less than one percent of the adjusted contract price, nor less than $500.00.”

On-street-parking removal creates a hardship for residents and businesses. The contractor shall plan and execute the work to be done so that on street parking removal is no more than a total of three weeks in one area. Parking removal time span starts when “no parking” signs are installed prior to milling a street and ends when the signs have been removed after the final layer of asphalt has been applied.

Pedestrian access shall be maintained in each direction (east/west and north/south) at each intersection. This will require the curb ramp construction to be staggered or temporary curb ramps be built.

PROJECT COMPLETION DATE PLUS WORKING DAYS

All major items of work shall be completed on or before October 23, 2026. After

October 23, 2026, the Contractor shall be allowed ten (10) working days to complete minor work items. The Contractor is advised that multiple crews may be needed to complete the work by this deadline. All street resurfacing shall be complete by October 23, 2026, and all travel lanes shall be open to traffic by that date. Pavement markings, clean-up, and other minor work items as determined by the Engineer may be completed after October 23, 2026.

The attention of each CONTRACTOR is directed to Article 108.09 of the

STANDARD SPECIFICATIONS, which indicates the schedule of deductions for overruns on the Contract time. Article 108.09 shall apply in the event that the

CONTRACTOR fails to complete the project by October 23, 2026.

Asphalt Binder Acceptance Procedure” with the following exceptions. Articles

3.1.9 and 3.4.1.4 of the policy memorandum will be excluded.

Revise Article 406.06(h)(2) of the Standard Specifications to read:

(2) Longitudinal Joints.

When the use of longitudinal joint sealant (LJS) is specified, it shall be applied below the surface course. The surface to which the LJS is applied shall be dry and cleaned of all dust, debris, and any substances that will prevent the LJS from adhering. Cleaning shall be accomplished by means of a sweeper/vacuum truck, power broom, air compressor or by hand. The LJS may be placed before or after the tack or prime coat. When placed after the tack or prime coat, the tack or prime shall be fully cured prior to placement of the LJS.

The LJS application shall be centered under the joint of the HMA lift being constructed within 2 in. (50 mm) of the joint.

A one-quart sample shall be taken from the pressure distributor or melting kettle at the jobsite once for each contract and sent to the Central Bureau of Materials.

The LJS shall be applied in a single pass with a pressure distributor, melter kettle, or hand applied from a roll for HMA lifts up to 2 in. (50 mm) in thickness. The LJS shall be applied in two passes for HMA lifts between 2 and 4 in. (50 and 100 mm) in thickness. At the time of installation, the pavement surface temperature and the ambient temperature shall be a minimum of 40 °F (4 °C) and rising.

The LJS shall be applied at a width of not less than or greater than 1 ½ in. (38 mm) of the width specified. If the LJS flows more than 2 in. (50 mm) from the initial placement width, LJS placement shall stop, and remedial action shall be taken.

When starting another run of LJS placement, suitable release paper shall be placed over the previous application of LJS to prevent doubling up of thickness of LJS.
