The Department will assess liquidated damages for each calendar day the work (project) is late until the Contractor substantially completes the work. The Department will count calendar days in accordance with Section 8.6 B.

Following the substantial completion of the Phase 1, 2, 4, and 5 portions of the project, the Department will allow single lane closures for the completion of the remaining items of work (including, but not limited to, permanent pavement markings, placement of granular base for shared use path, asphalt surfacing for shared use path, and permanent erosion control measures).

In the event the Contractor does not complete all field work on time, the Department will count calendar days in accordance with Section 8.6 B.

Time Extensions

In order to avoid or reduce liquidated damage and disincentive assessments, the Contractor may request a time extension for any calendar day count completion requirement, any interim completion requirement, the field work completion requirement, or all completion requirements. The Department will consider these time extension requests using the same considerations that apply when granting an extension of contract time under Section 8.7, except extra work or an increase in quantities will not qualify for an extension of time based solely on a proportional increase in the contract amount.

Expected Adverse Weather Days

The Department has provided Attachment 1 for information purposes only as a guide to bidders. This table depicts the typical number of adverse weather days expected for any given month, based on historical records. The Department will consider this project a grading project in Zone 6.

The Department will consider expected adverse weather days cumulative in nature over the time period when the Contractor is actively pursuing completion of the work. The Department will not consider adverse weather days during an extended period of time when the Contractor is not pursuing completion of the work. When considering a time extension for a calendar day count completion requirement, interim completion requirement, substantial completion requirement, field work completion requirement, or all completion requirements, the Engineer will compare the total number of expected adverse weather days against the total number of actual adverse weather days for the time period during which the work was being completed.
