Identification of interface and contractual
milestones
The contractor
shall submit for approval, prior to the submission of the Baseline Schedule,
the proposed Activity Coding dictionary.
Activity Numbering
The contractor
shall propose, prior to the submission of the Baseline Schedule, an activity
numbering scheme that helps identify activities by location and responsibility
(including any sub-contractor). In any event all activity numbers shall
commence with the three characters “MFT”
Resource and Cost Loading
Each Activity
shall be loaded with relevant costs and resources. The contractor shall submit
his proposed resource and cost dictionaries for review and acceptance. PMO may
elect to provide a resource dictionary for use by the contractor; in this case
contractor shall not make modification to the dictionary without consent of
PMO.
The quantities and
unit rates of items in the Contract shall be used to arrive at resource and
cost loading for activities. Total Cost loaded on the activities shall be equal
to total contract value. The cost loaded to activities for each location /
element / item of work should match the contract price for the same in the
Contract.
Client Server
Amana may
decide to have the baseline and progress schedules reside on the agency
computer server, to which the contractor shall be granted suitable access. The
Employer, PMO and Supervising Engineer shall have access to view the baseline
schedule. The Employer and the PMO shall be granted access to the schedule for the
purpose of monitoring and creating inter-contract logic links.
Narrative
A narrative shall accompany the baseline schedule that
describes the key aspects of the submitted schedules. The narrative shall define the key
aspects of the contractor’s plan for conducting the works that includes the
following key sections:
1. The
layout and logic used in the schedule.
2. Critical
submittals.
3. The
critical path.
4. An
overall float analysis.
5. Any
interface concerns (input by other parties to be identified).
6. Productivity
or any other assumptions made to determine activity durations
7. Calendars
that have been applied to activities and the rationale for any deviation from
the standard calendar.
Critical Path
In addition to
preparing the baseline schedule according to the above requirements, the
schedule shall also be sorted by critical path derived by the baseline schedule
and presented as such. This schedule shall show the critical path derived from
the baseline schedule. This is a time-scaled network logic diagram showing only
the current critical path of the works along with its current progress. In the
event of near critical path work (less than 10 days of float), the PMO may
request the near critical path items also be shown.
Manpower Histogram
A manpower
loading histogram shall be developed as part of the baseline schedule. The histogram
shall show overall manpower required for the works and what disciplines make up
the overall manpower
Cost Curve (S-Curve)
A Cost loading
curve shall be developed as part of the baseline schedule. The curve shall show
overall contract price, the Contractor may be asked to develop curves for major
elements constituting the contract scope.
Working Calendar
The working
calendar used in scheduling should reflect Fridays and official holidays as
non-working days. The schedule should be based on working hours as defined in
the contract or officially proposed by the contractor and approved by Amana.
1.4 Progress
Schedule / Schedule updates
The first
update to the approved baseline schedule forms the first progress schedule.
Subsequent progress schedules shall be submitted on a fortnightly or weekly basis
(as directed by the PMO) presenting the update for the previously issued
progress schedule. The progress schedule shall also be used to: confirm the percent complete requested by the
contractor in progress payment applications; analyze delays and impacts in all
time impact analysis (TIA); and, determine whether a recovery schedule is
required from the Contractor.
Narrative
The contractor
shall submit a narrative as a part of the progress schedule submission. These
submissions are required to be stand-alone documents and shall not require
their corresponding progress schedules to be attached in order to understand
the narrative. The narrative shall address the following, but not be limited
to:
1. Progress
in last period.
2. Critical
path progress and concerns.
3. Potential
delays and TIA.
4. Submittal
status (focus on critical submittals and concerns).
5. Manpower
loading (by discipline).
6. Revenue
to-date.
7. Variances.
The contractor shall provide a written narrative to include the cause(s) of all
schedule variance(s) related to a forecasted delay in any contractual milestone
completion or activity dates.
8. Additional
activities required for the update.
Critical Path
In addition to
preparing the progress schedule according to the above requirements, the
schedule shall also be sorted by critical path derived first by the baseline
schedule, and subsequently, from the current progress schedule. This is a
time-scaled network logic diagram showing only the current critical path of the
works along with its current progress. In the event of near critical path work
(less than 10 days of float), the PM may request the near critical path items
also be shown.
Manpower Histogram
The manpower
loading curve shall be updated in accordance with the progress schedule to show
the actual manpower deployed compared to the Baseline Schedule.
Cost Curve (S-Curve)
A Cost loading
curve(s) shall be updated in accordance with the progress schedule to show the
actual earned value compared to the Baseline Schedule
1.5 Recovery
Schedule
In the event
that certain conditions exist such that any contractual milestone date is in
jeopardy of being delayed, the contractor shall submit a recovery schedule for
the Amana’s approval. The schedule shall
be accompanied by a narrative describing what steps the contractor proposes to
recover slippage.
1.6 Extension of Time Schedule
In the event
that conditions exist such that the contractor believes there are grounds for
an extension of time, the contractor shall submit as part of his application a
schedule showing how the works have been impacted by delay events. The schedule
to be used to demonstrate entitlement shall be the progressed schedule in place
at the time of the occurrence of the delay event and the method of calculation
shall be Time Impact Analysis (TIA).
Where
entitlement is claimed as a result of a change of scope to the works the
contractor shall produce a schedule Fragnet that demonstrates the impact of the
change.
1.7 Look Ahead
Schedule
The contractor
shall prepare and submit on first working day of each week a Look Ahead
Schedule showing specific activities scheduled for four weeks period, three
following weeks and one prior week. Review / discussion on the schedule shall
be an agenda item at weekly progress meetings. It is important to note that
this schedule is not to be generated by running a filter on primavera project
schedule, it shall have greater level of detail and reflect actual site
conditions and resources availability.
1.8 As-Built
Schedule
Upon completion of each
Contract, the contractor shall prepare an as-built schedule from the data
gathered during the progress of the project.
The as-built Schedule shall be compared to the Baseline Schedule and the
delays must be analysed and justified.
This is part of the project closeouts requirement.
2 SOFTWARE
& SCHEDULE Format
2.1 Software
Unless otherwise
specified, the preliminary, baseline, and progress schedules shall be produced
utilizing the Windows-based Primavera Project Management Tool. All submissions
shall be in the latest commercially available version of Primavera.
2.2 Critical Path Method (CPM)
The
preliminary, baseline, and progress schedules shall employ the critical path
method (CPM) using retained logic for the planning, scheduling and reporting of
the work to be performed under this contract agreement.
2.3 Schedule Components
The preliminary,
baseline, and progress schedules shall include, but not be limited to:
