Form 43 will establish construction targets for Asphalt Cement and all mix properties at Air Voids up to 1.0 percent below the mix design optimum. CDOT will establish the production asphalt cement and volumetric targets based on the Contractor’s mix design and the relationships shown between the hot mix asphalt mixture volumetric properties and asphalt cement contents on the Form 429. CDOT may select a different AC content other than the one shown at optimum on the Contractor’s mix design in order to establish the production targets as contained on the Form 43. Historically, Air Voids adjustments typically result in asphalt cement increases from 0.1 to 0.5 percent.

Contractors bidding the project should anticipate this change and factor it into their unit price bid.

The Contractor shall prepare a quality control plan outlining the steps taken to minimize segregation of HMA. This plan shall be submitted to the Engineer and approved prior to beginning the paving operations. When the Engineer determines that segregation is unacceptable, the paving shall stop and the cause of segregation shall be corrected before paving operations will be allowed to resume.

The hot mix asphalt shall not contain any reclaimed asphalt pavement.

Subsection 403.03 shall include the following:

Asphalt shall be placed with self-propelled, activated screed assembly pavers. The pavers shall have sufficient power to propel themselves and the hauling equipment without adversely affecting the finished pavement surface.

The paver hopper shall be equipped with a distribution system to place the mixture uniformly in front of the screed without segregation. The screed shall effectively produce a finished surface of the required thickness and texture without tearing, shoving, or gouging the mixture.

TRAFFIC CONTROL PLAN - GENERAL

The key elements of the Contractor’s method of handling traffic (MHT) are outlined in Subsection 630.10(a).

The components of the TCP for this project are included in the following:

(1) Section 104.04 and Section 630 of the specifications

(2) CDOT Standard Plans

(3) Schedule of Construction Traffic Control Signs

(4) Construction Phasing Plans

(5) City of Colorado Springs Manual on Uniform Traffic Control Devices – Supplement for the City of

Colorado Springs.

Unless otherwise approved by the Engineer, the Contractor’s equipment shall follow normal and legal traffic movements. The Contractor’s ingress and egress of the work area shall be accomplished with as little disruption to interstate highway, state highway, and local road traffic as possible.

Traffic control devices shall be removed by picking up the devices in a reverse sequence to that used for installation.

This may require moving backwards through the work zone. When located behind barrier or at other locations shown on approved traffic control plans, equipment may operate in a direction opposite to adjacent traffic.

The City may have entered into operating agreements with one or more law enforcement organizations for cooperative activities. Under such agreements, at the sole discretion of the City, law enforcement personnel may enter the work zone for enforcement purposes and may participate in the Contractor’s traffic control activities. The responsibility under the Contract for all traffic control resides with the Contractor and any such participation by law enforcement personnel in Contractor traffic control activities will be referenced in either the Special Provisions or General Notes of the plans depending on whether the Contractor is to hire local law enforcement or if the City is contracting with Colorado State Patrol for uniformed traffic control. Nothing in this Contract is intended to create an entitlement, on the part of the Contractor, to the services or participation of the law enforcement organization.

Special Traffic Control plan requirements for this project are as follows:

During the construction of this project, traffic shall use the present traveled roadway unless identified on the plans or approved by the Engineer.

The Contractor shall not have construction equipment or materials in the lanes open to traffic at any time, unless approved by the Engineer.

Throughout the duration of the project, reasonable access shall be provided to residents within the work zone. Prior to the pre-construction meeting, the Contractor shall provide a written accessibility plan for each Phase to the City, outlining the Contractor’s plan to provide access to residents throughout the duration of the project. Due to limited parking accommodations within the existing right-of-way, the Contractor shall provide a safe pedestrian accessible route to residents within the work zone in such a manner that residents shall not be required to walk more than 100’ from their residence to the beginning of the work zone. At the end of each work day, the Contractor shall place steel plates, and provide other forms of protection within the construction area to allow safe passage of vehicles for residents.

The Contractor shall assist residents to ensure that trash pickup and mail collection is not interrupted.

At least one week prior to starting construction, the Contractor shall notify the City of Manitou Springs’ City Engineer of the date the Contractor intends to start construction.

All costs incidental to the foregoing requirements shall be included in the original contract prices for the project.

The work described in these plans and specifications requires coordination between the Contractor and the utility companies in accordance with Subsection 105.11 in conducting their respective operations as necessary to complete the utility work with minimum delay to the project.

All new underground facilities, including laterals up to the structure or building being served, installed as part of this project must be electronically locatable when installed, in compliance with Colorado Revised Statutes, Title 9, Article 1.5.

PART 1 - CONTRACTOR SHALL PERFORM THE WORK LISTED BELOW:

Coordinate project construction with performance by the utility owner of each utility work element listed in Part 2 below. Perform preparatory work specified in Part 2 for each utility work element. Provide an accurate construction schedule that includes all utility work elements to the owner of each impacted utility. Provide each utility owner with periodic updates to the schedule. Conduct necessary utility coordination meetings, and provide other necessary accommodations as directed by the Engineer. Notify each utility owner in writing, with a copy to the Engineer, prior to the time each utility work element is to be performed by the utility owner. Provide notice, as specified in Part 2, immediately prior to the time the utility work must begin to meet the project schedule.

Provide traffic control, as directed by the Engineer, for any utility work performed by the utility owner within the project limits expected to be coordinated with construction. However, traffic control for utility work outside of typical project work hours shall be the responsibility of the utility owner.

Perform each utility work element for every utility owner listed in Part 1. Notify each utility owner in advance of any work being done by the Contractor to its facility, so that the utility owner can coordinate its inspections for final acceptance of the work with the Engineer. Obtain written acceptance from the utility owner for work performed by Contractor.

Request and receive utility locates prior to commencing any type of excavation. Based upon these locates, guardrail and other improvements may need to be adjusted as directed by the Engineer to avoid a utility. Hand digging, non-
