The Contractor’s schedule shall be submitted to the Engineer within seven (7) calendar days from the date of Contract Award. This schedule once reviewed by the Engineer and if it meets the Contract requirements, will become the Contract Construction Schedule against which progress will be measured.

The proposed Contract Construction Schedule shall be submitted for acceptance in its optimum leveled form. This presentation should be in bar (Gantt) chart form. The schedule shall be created using Microsoft Project or approved equal and submitted in electronic format and six (6) hardcopies shall be delivered to the Engineer. The Contractor’s schedule shall be subdivided into work areas, as applicable, including mobilization and demobilization activities. (Failure to comply with this requirement shall result in a payment deduction of $500.00. Payment deduction shall be assessed on the next following progress payment certificate).

Schedule Maintenance and Updates

The updated Contract Construction Schedule shall be updated bi-weekly and submitted in electronic format and six (6) hardcopies shall be delivered to the Engineer a minimum of three (3) business days

prior to the scheduled Construction Progress Meeting to permit a detailed review by the Engineer and the Owner in advance of the meeting. The updated Contract Construction Schedules shall reflect any changes to the Contract Construction Schedule and shall also include both the baseline and actual work. (Failure to comply with these requirements shall result in a payment deduction of $500.00 for each occurrence, to reconcile additional costs to the Owner as a result of additional follow-up activities undertaken by the Engineer. Payment deduction shall be assessed on the next following progress payment certificate).

Progress will be reviewed at the Construction Progress Meetings. The following will be reviewed at these meetings:

• Progress during report period • Review of number of elapsed Working Days • Work scheduled for the next period – forecast vs. baseline • Anticipated problems and proposed solutions • Review of logic for decisions impacting schedule • Analysis of alternative methods to mitigate any accumulated delays • Revisions to Contract Construction Schedule and time impact analysis • Updated Contract Completion Date, if applicable

From time to time, the Engineer or the Owner may require the Contractor to provide elaboration on any part of the Contract Construction Schedule to explain and demonstrate the construction sequence forecast therein. The expanded schedule shall comply with the submissions requirement of this specification.

From time to time, the Engineer or the Owner may require the Contractor to provide additional details, marked up drawings, plans or profiles or additional information which complements the Contract Construction Schedule submission. The Contractor shall comply with these requests.

Schedule Revisions

Maintenance and update of the Contract Construction Schedule to reflect actual progress up to the cut-off date shall not be considered a revision to the Contract Construction Schedule. All other changes, including, but not limited to, the following shall be considered Contract Construction Schedule revisions.

• Adding and/or deleting activity relationships • Adding and/or deleting activities • Changes to original durations • Changes to Contract milestone dates or constraint dates • Performance of work out of sequence • Scope of changes through Change Orders

If, as a result of the construction schedule update, it appears the updated schedule no longer represents

the actual execution and progress of the Work, the Engineer will request a revision to the Contract Construction Schedule.

Before any revisions are incorporated into the Contract Construction Schedule, the Engineer and the Owner must accept the basis of the revisions.

Contract Schedule Recovery

When the schedule update indicates that the key dates, milestones and phasing of the Work established in the Contract Construction Schedule will not be met, the Contractor shall promptly undertake appropriate Contract Construction Schedule recovery action.

Within seven (7) calendar days of receiving a request from the Engineer, the Contractor shall submit a written recovery statement to the Engineer describing the cause for any slippage and the actions planned to recover the original Contract Construction Schedule in the shortest reasonable time. (Failure to comply with the request of the Engineer shall result in a payment deduction of $500.00. Payment deduction shall be assessed on the next following progress payment certificate).

Appropriate recovery actions may include, but not limited to, assignment of additional labour or equipment, shift or overtime work, expediting submittals or deliveries, overlapping of activities or sequencing changes to increase activity.

Refusal, failure or neglect to undertake appropriate recovery action shall constitute reasonable evidence that the Contractor is not executing the Work with the diligence that will ensure its completion within the approved Contract Construction Schedule, and will constitute sufficient basis for the Owner to withhold any payment otherwise due, and identify and order alternative recovery actions.

All costs for providing Contract Construction Schedules in accordance with the foregoing requirements shall be considered incidental to the Work.

Payment

Costs associated with seasonal weather conditions and any requirements that work be performed on weekends, after normal working hours, on statutory/civic holidays, or in multi-shifts, and other incidental costs shall be borne by the Contractor, including any directions by the Engineer for the Contractor to work extra hours if the Work falls behind.
