NATC – REFINISH 1ST FLOOR ADMIN HEADQUARTERS 6

completion. The status date of each schedule update shall be 10 days before the progress payment request date.

Construction work shall not begin until government approval is obtained for all required preliminary submissions.

Purpose: The purpose of the project schedule is to ensure adequate planning, coordination, scheduling, and reporting during execution of Construction activities of the Contractor. The project schedule will assist the Contractor and the Contracting Officer Representative in monitoring the progress of the work, evaluating proposed changes, and processing the Contractor's monthly progress payment requests.

Software: The software shall be the latest version of Microsoft Project, or approved equal.

Schedule Development: The project schedule shall cover the entire contract period. The late finish date of the project schedule shall be the same date as the established completion date of the contract.

The Contractor shall use the Critical Path Method (CPM) with limited use of lead or lag durations between schedule activities. The Contractor's project schedule shall consist of procurement activities (including mobilization, submittal, and the delivery long-lead procurement items) and construction activities.

The Contractor's project schedule shall consist of, but not be limited to, the following for each activity:

Identify each and every activity number with numerical designations (maximum 5-digit).

Numbering of activities shall be in increments of 10.

Concise description of the work represented by the activity (maximum 48 characters). Avoid the use of non-standard abbreviations. The work related to each activity shall be limited to one work trade.

Activity duration in whole working days with a maximum duration of 15 workdays each, unless otherwise approved by the Contracting Officer, except for non-construction activities including mobilization, shop drawing and sample submittals, fabrication of materials, delivery of materials and equipment, and concrete curing.

In developing the project schedule, the Contractor shall be responsible for ensuring that subcontractor work at all tiers, as well as its own work, is included in the project schedule.

The project schedule, as developed, shall show the sequence and interdependence of activities required for complete performance of the work. The Contractor shall be responsible for ensuring all work sequences are logical and the project schedule shows a coordinated work plan. Proposed durations assigned to each activity shall be the Contractor's best estimate of time required to complete the activity considering the scope and resources planned for the activity. Resource loading of each activity shall list all personnel by labor category and equipment type and capacity proposed to complete the activity in the duration shown. Include permit requirements and constraints. Seasonal weather conditions shall be considered and included in the planning and scheduling of all work influenced by high or low ambient temperatures, wind and/or precipitation to ensure completion of all work within the contract time.

Project Schedule Updates

Monthly updates: The monthly updating of the project schedule shall be an integral part and basic element of the estimate upon which progress payments shall be made under this contract. If, in the

NATC – REFINISH 1ST FLOOR ADMIN HEADQUARTERS 7

judgment of the Contracting Officer Representative, the Contractor fails or refuses to provide a schedule of values and a complete schedule update or revision as specified hereinafter, the Contractor shall be deemed to have not provided the required information upon which the progress payment may be made, and shall be subject to retainage of a portion of the payment.

Narrative: The report shall include a brief description of the actual progress made during the update period; actual and potential delaying activities; any impediments to progress; issues related to inclement weather; progress toward established milestones and project float. The report shall include a brief description of the work anticipated to be performed in the next month. Any minor revisions to the schedule should be identified so they can be evaluated and accepted or rejected.

As the Work progresses, indicate Actual Completion percentage for each activity.

If the schedule update shows a late finish date after the contract completion date, at a minimum, include the following in the narrative with your submission:

Any known delays.

Actions that will be taken to get back on schedule.

Pending modifications.

Impediments or constraints affecting progress.

Progress Payments: The monthly updating of the currently accepted Construction Schedule shall be an integral part of the process upon which progress payments will be made under this contract. If the Contractor fails to provide schedule updates or revisions, then a portion of the monthly payment may be retained until such corrections have been made.

Time Impact Analysis for Contract Modifications, Changes, Delays, and Contractor Requests Requirements: When contract modifications or changes are initiated, delays are experienced, or the Contractor desires to revise the project schedule, the Contractor shall submit to the Contracting Officer Representative a written time impact analysis illustrating the influence of each modification, change, delay, or request on the contract time.

Time Extensions: Activity delays shall not automatically mean that an extension of the contract time is warranted or due the Contractor. It is possible that a modification, change, or delay will not affect existing critical activities or cause non-critical activities to become critical. A modification, change, or delay may result in only absorbing a part of the available total float that may exist within an activity chain of the project schedule, thereby not causing any effect on the contract time. Time extensions will be granted in accordance with the terms of the contract.

Float: Float is not for the exclusive use or benefit of either the National Park Service or the Contractor. Extension of the contract time will be granted only to the extent the equitable time adjustments to the activity or activities affected by the modification, change, or delay exceeds the total (positive or zero) float available on a particular activity.

2.2 Construction Requirements

Minimize Construction Impacts

The following mitigation measures shall be implemented to minimize the impacts of construction activities:

NATC – REFINISH 1ST FLOOR ADMIN HEADQUARTERS 8
