THE STANDARD SPECIFICATIONS, SERIES 2001, ARE AMENDED BY THE FOLLOWING MODIFICATIONS AND ADDITIONS. THESE ARE SUPPLEMENTAL SPECIFICATIONS AND THEY SHALL PREVAIL OVER THOSE PUBLISHED IN THE STANDARD SPECIFICATIONS.

01017.01 MOBILIZATIONS, EROSION CONTROL.

Prior to the Preconstruction Conference, the Contractor shall submit for approval an Erosion Control Implementation Plan (ECIP) for accomplishing all aspects of the erosion control work. The ECIP shall also include a description of any additions or modifications to the project. Deviations from the approved ECIP shall not be implemented without written permission from the Engineer. The Contractor and Engineer shall review and modify the ECIP as needed during the course of the project.

The ECIP shall include stages for erosion control work to address the Contractor’s timetable and sequence for major activities on the project, including the number of Mobilizations, Erosion Control, anticipated for the project. The number of mobilizations shall consider, as a minimum, clearing and grubbing activities, the number of earthwork balances for the project, sensitive areas requiring special consideration, anticipated suspension of work, and compliance with the Pollution Prevention Plan (PPP).  The Contractor shall consider separate mobilizations needed for different crews performing work such as silt fence, seeding, or ditch checks. However, multiple mobilizations shall will not be paid for a single crew performing different items of work that require the same equipment to be mobilized.

Only one mobilization will be paid for each stage of work described in the ECIP. Within the scope of work defined for each single mobilization described in the ECIP, additional movement due to weather delays or at the option of the Contractor shall will not be counted as a mobilization.

Additional mobilizations not outlined in the ECIP must be approved by the Engineer. Only one mobilization will be paid for each stage of additional work approved by the Engineer.

The Contractor shall mobilize with sufficient labor, equipment, and materials to perform the erosion control included in the ECIP. If the Contractor fails to mobilize when erosion control work is needed to comply with the ECIP and the PPP, the Engineer will direct the Contractor to mobilize within 72 hours of a written order.  Notification shall will be given to the Contractor.

If the Contractor fails to mobilize within such time period, a deduction of $300.00 $750.00 per calendar day will be made from money due under the contract, except when such time period is extended by the Engineer.

This item shall not include work provided under the item of Mobilizations, Emergency Erosion Control.

01017.02 MOBILIZATIONS, EMERGENCY EROSION CONTROL.

The Contractor shall mobilize with sufficient labor, equipment, and materials, on the job site within 8 hours of a written order by the Engineer to install temporary erosion control items on an emergency basis. The written order by the Engineer will include a description of the required work. Only one mobilization will be paid for the work described in the written order.

Notification shall will be given to the Contractor.  If the Contractor fails to mobilize within such time period, a deduction of $300.00 $1500.00 per calendar day will be made from money due under the contract, except when such time period is extended by the Engineer.

An emergency shall will be considered to be a sudden occurrence of a serious and urgent nature, which requires work not included in the contract or is beyond normal maintenance of erosion control items and the mobilizations included in the erosion control implementation plan. Emergency work requires immediate mobilization and movement of necessary labor, equipment, and materials to the emergency site, followed by the immediate installation of temporary erosion control measures.
