Description

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

155.02 Definitions.

(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.

Construction Requirements

155.03 General.

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.

(1) Time-scaled logic diagram.

(c) Show original and remaining durations for construction activities. Break construction activities into subtasks with activity durations no longer than 20 workdays.

(d) Show original and remaining durations of non-construction activities (such as mobilization and submittals). Include pay item number, and the fabrication and delivery of key materials. Non-construction activities may have durations exceeding 20 workdays consistent with the contract. Indicate intended submittal dates and delivery dates for fabrication and delivery activities. Allow for review of each submittal.

(e) Start the construction schedule with the date of the NTP and conclude with a milestone that shows the contract completion date.

(f) Show total float and free float.

(g) Show relationship lines. Include at least one predecessor and one successor activity for each activity, except for the NTP and contract completion date.

(h) Show the sequence and interdependence of all activities.

(2) Tabular schedule. Submit a tabular schedule sorted by total float. Include the following information in the tabular schedule:

(a) Activity number;

(b) Activity description;

(c) Activity percent complete;

(d) Original and remaining duration;

(e) Early and late schedule dates;

(f) Total float;

(3) Written narrative. Describe the rationale and assumptions used in the development of the construction schedule. Ensure there are no conflicts between the diagram and the narrative. Include the following:

(d) Description of workdays per week, number of shifts per workday, and number of hours per shift.

(e) Include anticipated holidays, non-workdays, winter shutdowns, and other constraints within the contract. Describe calendars used in the schedule module and list the calendar used for each activity in the schedule module.

(f) Name of the subcontractor or supplier performing an activity on the schedule diagram. State assumptions made in the scheduling of the subcontractor’s or supplier’s work.

(g) Description of site mobilization and critical delivery dates for equipment and material that can affect completion of the project.

(h) A description of organizational limitations (such as resource constraints or subcontractor commitments) which limit scheduling flexibility.

(i) A list and description of constraints used in the CPM scheduling software.

(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:

(a) Pay item number and description;

(b) Planned date of initial submittal; and

(c) 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.
