CONSTRUCTION SEQUENCE

Prepare construction schedules using CPM, under concepts and methods outlined in the AGC Manual.

1. Establish workday calendar(s) and use these in the schedule to translate the activity’s workday duration into calendar dates. Use calendar names unique for this project, do not use software default calendar names. Save calendars as project calendars, not global calendars.

2. Prepare schedule based on required sequence and interdependence of activities.

3. Prepare detailed activity network for accomplishing required work organized by Work Breakdown Structure (WBS).

\\dowl.com\j\Projects\26\12494-01\81Specs\Lat73-36\01 32 16 - Construction Schedule.docx 01 32 16-3

4. Activities except “Award” shall have predecessor activities and activities except “Contract Complete” shall have successor activities.

5. Include dates for interim milestones, critical interface events for BIA Representative, time or seasonal constraints specified in the contract documents, and contract completion.

6. Include work to be performed by subcontractors.

7. Develop the Construction Program to account for seasonal weather conditions.

8. If activity codes are utilized, use unique activity code names assigned as project codes rather than global codes. Utilize the WBS, in lieu of activity codes, for general organization of the schedule.

9. Define activities to a level of detail to result in no single activity having a duration greater than 20 workdays, unless otherwise accepted by BIA Representative.

a. Durations for administrative activities (e.g., submittals and reviews, fabrication, manufacturing) or other specific activities identified in the contract will not be subject to the workday limitation.

10. Include activities for BIA Representatives review and approval. Assign submittal review activities to a 7-day calendar with durations as specified in Section 01 33 00 – Submittals.

Include activities for issuance of submittals, submittal reviews, and fabrication or manufacturing activities when work involves significant quantities, long lead times, is on the critical path, or as requested by the BIA Representative.

11. Include contract title, contract number, and Contractor’s name on each sheet of the Gantt chart.

12. For each activity on the Gantt chart, display identification number, activity description, planned duration, start date, finish date, total float, and calendar identification.

13. Include table of abbreviations used in the schedule, listed, and defined alphabetically.

14. Use durations in units of whole workdays.

15. Equate durations for BIA Representative reviews and other identified actions to the maximum number of calendar days specified in their respective paragraphs.

Baseline Schedule:

1. Represents Contractor’s as-planned approach to accomplishing the work. Does not include actual start dates, percent completes, or actual finish dates.

Updated Schedule:

1. Meet weekly with the BIA Representative at a location approved by the BIA Representative, to review progress. Establish dates that activities were started and completed, discuss remaining durations for each activity started but not yet completed.

a. Discuss schedule status and identify potential negative schedule impacts.

b. Submit revised schedule that accurately identifies actual start/finish dates, identifies corrective actions to recover schedule, or request approval to extend the construction schedule.

\\dowl.com\j\Projects\26\12494-01\81Specs\Lat73-36\01 32 16 - Construction Schedule.docx 01 32 16-4

2. Provide a 3-week look-ahead schedule at weekly progress meetings.

3. Following receipt of an executed contract Modification, incorporate the activity data and logic relationships stipulated in the modification into the schedule for discussion at the next progress meeting.

4. The project schedule shall be updated and submitted to the BIA Representative for approval with the Contractor’s monthly progress payment.

5. Assign a unique project file name to each schedule update issued. Schedule updates shall be issued as a pdf and comply with the following file naming convention:

YYMMDD_CRIP Lateral 73-36 Check 1 Replacement Schedule Update.pdf

TIME IMPACT ANALYSIS

Provide a time impact analysis for contract changes, e.g., a change order, proposed modification, or value engineering change proposal, to support a claim or request for an equitable adjustment to the contract that involves a delay or accelerated schedule.

The BIA Representative may use the time impact analysis to determine if a time extension or reduction to the contract milestone dates is justified.

A time impact analysis is applicable whether the Contractor’s current schedule milestone dates are the same as, earlier, or later than those required under the contract.

Changes, additions, or deletions to activities, activity durations, or activity time frames will not automatically mean that an extension or reduction of contract time is warranted.

Time extensions for performance will be considered only to the extent that the Contractor’s current scheduled milestone dates exceed the contract milestone dates.

For each activity directly affected by a change or delay, include the current and proposed items:

1. Activity description

2. Types and quantities of major pieces of equipment, principal manpower, and pacing materials (materials that affect activity start, duration, or finish).

3. Activity duration.

4. A narrative containing the rationale used in developing the proposed logic relationships and activity data.

Float is not for the exclusive use by, or benefit of, either the BIA Representative or the Contractor.

Prepare a single time impact analysis for modifications issued after Notice to Proceed (NTP) and prior to approval of the baseline schedule. Submit the time impact analysis with the baseline schedule submittal.

Perform time impact analyses using data in the current, approved schedule at the time of the change or delay event.

1. Prepare proposed revised schedule and narrative description describing and highlighting where changes or delays are included.

\\dowl.com\j\Projects\26\12494-01\81Specs\Lat73-36\01 32 16 - Construction Schedule.docx 01 32 16-5

2. Prepare summary comparing the results of two schedule analyses: One using current schedule data, and one using proposed schedule data incorporating the changes or delays.

a. Show contract milestone and activities whose periods of performance have shifted.

b. Base mathematical analyses on status of work and available float from the time the CO directs or proposes changes to the work, the Contractor submits a value engineering change proposal, or when a delay occurs.

REVIEW AND EVALUATION

Baseline Schedule:

1. Within 14 calendar days after receipt of baseline schedule:

a. BIA Representative will accept or reject the proposed baseline schedule.

b. If schedule is rejected, revise and resubmit within 7 calendar days following the date of rejection.

2. Do not proceed with onsite work, except for mobilization and survey, until baseline schedule has been accepted.

Updated Schedules:

1. The BIA Representative will require 7 calendar days after receipt of each monthly update to review and accept or reject the updated schedule.

2. If the updated schedule is rejected, revise, and resubmit updated schedule within 2 calendar days following the date of the rejection letter.

3. The BIA Representative will schedule a pre-submittal meeting with the Contractor’s representative to review a draft updated schedule prior to the Contractor submitting the monthly Updated Schedule. Contractor will be required to provide weekly schedules starting one week before Phase 2 and for the duration of Phase 2. Contractor and BIA Representative will conduct a pre-submittal meeting two days before each Updated Schedule is submitted.

Failure to include any element of the work in the schedule will not release Contractor from completing work required by the contract.
