Description

155.01 This work consists of scheduling, monitoring, and reporting the progress of construction activities.

(a) Baseline construction schedule. The first approved construction schedule submitted showing the order to perform the work, and the dates for starting and completing the work. Once approved the baseline construction schedule cannot be changed.

(b) Construction Schedule CPM schedule. A CPM schedule includes a time-scaled logic diagram, tabular schedule, written narrative, and a submittal list.

The time-scaled logic diagram is a computer-generated diagram showing the sequence in which the Contractor, in coordination with subcontractors, plans to perform the work; the interdependence of all activities and milestones; the work completed through the data date; and the remaining work necessary to complete the project.

(c) Construction schedule update. An update to the previously approved construction schedule that shows the completed work and the remaining work necessary to complete the project and includes progressing of the schedule, changes to the schedule logic, changes to the schedule activities, changes to the activity durations, or any other modification to the schedule of planned work. A construction schedule update may show construction being completed at a date other than the contract completion date.

(d) Critical path. The longest sequence of activities in the CPM schedule that determines the project’s duration. If the duration of any activity on the critical path is changed, the time required to complete the project will change unless a separate CPM schedule adjustment is made.

Designate an individual who will be the authorized representative responsible for the schedule. Submit the name of the authorized representative with the baseline schedule submission.

Failure to include elements of work in the schedule that are required for performance of the contract, even if approved by the Government, will not excuse the Contractor from completing the work required by the contract completion date.

Approval of the construction schedule does not relieve the Contractor of the responsibility to schedule the work to meet the contract requirements.

Do not suppress or sequester float. Do not alter planned durations and sequencing to give the appearance that activities do not have float. Float time within the construction schedule is not for use or benefit of either the Government or the Contractor but is a jointly owned project resource available to both parties as needed to meet the contract completion date. Either party has the full use of float until it is depleted.

155.04 Baseline Construction Schedule. Submit a construction schedule within 7 days of the NTP. Include a title page or header block with the contract number, project name, Contractor name, contract completion date, date of submittal, and submittal number. Show all activities.

Prepare and submit a CPM construction schedule.

CPM schedule. Depict the order and interdependence of all activities and the sequence of the work that will be accomplished by the Contractor and subcontractors.

Do not provide logic relationships between unrelated activities. Do not constrict start or finish dates without rationale.

Obtain approval before using lags or leads in the construction schedule. Remove lags or leads and replace with an activity identifying the lag or lead upon request.

Activity number;

Activity description;

Activity percent complete;

Original and remaining duration;

(4) Submittal list. Submit a list of drawings and other submittals by pay item number required for the entire contract period. Include the following information for each drawing or submittal:

1. Pay item number and description;

Planned date of initial submittal; and Planned date of CO’s initial response.

Submit the construction schedule according to Subsection 104.04.

Within 7 days of submission, the construction schedule will be approved or rejected. If rejected, submit a corrected schedule within 7 days. If rejected again, schedule a meeting within 3 days to discuss corrections and submit another construction schedule.

If a construction schedule is not received within 14 days after the NTP is issued, the CO will withhold the progress payment h until the construction schedule is received.

The approved construction schedule with supporting documents becomes the baseline construction schedule.

Within 7 days of submission, the construction schedule update will be approved or rejected. If rejected, submit a corrected construction schedule within 7 days. If rejected again, schedule a meeting within 3 days to discuss corrections and submit another construction schedule.

Submitting a proposed construction schedule update is not considered a notification of delay or of other basis for change. Continue to submit monthly construction schedule updates until a construction schedule update is approved.

Approval of a construction schedule update showing completion past the fixed completion date will not alter the fixed completion date or affect the Government's rights under the contract.
