SUMMARY

This Section defines the process whereby the Contractor will develop the Schedule of

Values (lump sum price breakdown) for review and approval by the BIA Representative.

Monthly progress payment amounts for some bid items will be determined from the in-progress status (i.e., estimated percent complete) of the work features identified in Section

01 29 00 – Payment Procedures.

SUBMITTALS

Submit the following in accordance with Section 01 33 00 – Submittals.

01 29 73-1, Schedule of Values

1. Prepare and submit a detailed Schedule of Values for every work feature within 30 days from the date of Award or 14 days prior to the Pre-Construction Meeting, whichever occurs first.

2. The schedule of values must be sufficiently detailed to determine appropriate monthly progress payments.

3. The BIA Representative will be the sole judge of acceptable numbers, details, and descriptions of values established.

4. If, in the opinion of the BIA Representative, a greater number of Schedule of Values items than proposed is necessary, the Schedule of Values will be returned for revision.

5. Adjustments and Acceptance

a. During the Pre-Construction Meeting, the level of detail and value allocations will be discussed to determine if the Schedule of Values provides an acceptable level of detail to support interim progress payments for the work features. The CO’s review of the Schedule of Values submittal shall be returned to CONTRACTOR within 7 days following the Pre-Construction

Conference.

GENERAL

SECTION INCLUDES

This section covers the requirements for developing the baseline construction schedule and updating and maintaining the construction program.

REFERENCE STANDARDS

Associated General Contractors of America (AGC)

1. AGC Manual – Construction Planning and Scheduling Manual

DEFINITIONS

Schedule: Construction schedule using the Critical Path Method (CPM) of planning and scheduling a construction project. Activities are arranged based on activity relationships and network calculations identifying the “critical activities” that determine the earliest completion date.

Project Calendars: Cross reference between the number of workdays and calendar days. The project calendar serves as the basis for the day/date conversion and assigns workdays and non-workdays.

Resources: Equipment, labor or crews, materials, subcontractors, fabricators, manufacturers, and consultants.

SUBMITTALS

Submit the following in accordance with Section 01 33 00 – Submittals.

01 32 16-1, Representative Information

1. Designation of authorized representative to develop and maintain the Construction

Program. Representative shall be experienced in developing and maintaining construction schedules and knowledgeable of activities and progress on-site to develop and maintain accurate and reliable schedules.

01 32 16-2, Baseline Schedule

1. Include:

a. Definition of project Calendars.

b. Gantt Chart (bar chart) for project.

c. Narrative of the construction sequence.

d. Activity report including all logic constraints consisting of predecessors, successors, and constraint dates.

e. Table listing equipment, manpower, and material limitations used to produce baseline schedule.

J:\26\12494-01\81Specs\MC185_MC270\01 32 16 - Construction Schedule.docx 01 32 16 -2

01 32 16-3, Updated Schedule

1. Include:

a. Updated activity and milestone schedule summary.

b. Definition of project calendars if revised from baseline calendars.

c. Gantt chart for project.

d. Narrative report specifically stating status of project.

1. If negative float exists, cite specific actions and conditions which caused the “behind schedule” condition and provide proposed course of action to complete the project within the specified delivery time.

2. List of Contractor-initiated changes to the current schedule, including the reason for the change and any unresolved issues relating to the

Construction Program. COR and Owner Representative reserve the right to reject Contractor-initiated changes to the approved schedule.

e. Submittals register. Updated monthly register including: submittals as listed in submittal table, revised submittals, dates, and status. This register document is separate from the scheduling database.

01 32 16-4, Time Impact Analysis

1. Include:

a. Construction Program database with proposed revised activity and milestone data.

b. Proposed schedule revisions, specifically identifying changed or deleted activities and the impact on the completion date.

c. Narrative report explaining results and conclusions.

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).

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.

J:\26\12494-01\81Specs\MC185_MC270\01 32 16 - Construction Schedule.docx 01 32 16 -3

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.

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.

J:\26\12494-01\81Specs\MC185_MC270\01 32 16 - Construction Schedule.docx 01 32 16 -4

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 MC185/MC270 Check Rehabilitation 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.

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.

J:\26\12494-01\81Specs\MC185_MC270\01 32 16 - Construction Schedule.docx 01 32 16 -5

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.
