will use the schedule to assess impacts and to formulate the best methods to
complete the works on, or ahead of the contractual completion dates. The

be scheduled and performed pursuant to the provisions of the Contract including
any specific dates for Contract completion milestones, phase completion and the
like, or other requirements included in the contract agreement. The contractor
is responsible for completion of all aspects of the works in accordance with
the contract agreement.
At anytime
throughout the course of the works, the PMO reserves the right to require additional
activities to be added to the schedule to clearly define the contractor’s plan
and intentions regarding the execution of the works. In each instance, such
activities or changes shall be made by the contractor at no cost or delay to
the Employer.
The services
provided by the PMO, the existence of schedules, networks or any other charts
or services prepared or performed by the PMO, shall in no way relieve the
contractor of the responsibility for complying with all of the requirements of
the contract agreement works, including, but not limited to, the responsibility
for completing works within the period for completion of the works and the

sCHEDULES & SCHEDULE DOCUMENTS
The following
outlines the schedules and schedule documents required to be submitted by the
contractor, with each type. Submittal details for each schedule are provided in
Submittal Requirements.
1.1 Preliminary
Schedule
The preliminary
schedule shall be a schedule showing all activities and deliverables occurring
in the initial period of the contract and shall be resource-loaded. This
schedule shall be used for progress monitoring while the Baseline Schedule for
the entire contract is developed. The schedule should fully detail the first
120 days of the Program and the balance of the works at a summary level.
In general no
individual activity should have duration greater than 18 working days, where
the contractor believes an activity need to exceed this limit it should be
noted along with a rationale in the accompanying narrative.
Narrative
A narrative shall accompany the preliminary schedule
that describes the key aspects of the submitted schedules. The narrative shall
describe what is to be delivered by the contractor at each of the agreed
interim milestone dates. The preliminary schedule narrative shall define the
primary aspects of the contractor’s plan for conducting the works including,
but not limited to:
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
and other assumptions made to determine activity durations
1.2 Critical Path
In addition to
preparing the preliminary schedule according to the above requirements, the
schedule shall also be sorted by critical path and presented as such. This is a
time-scaled Gantt chart showing only the current critical path of the works
(activities with total float of less than one day)
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.
1.3 Baseline Schedule
The Baseline
Schedule is a detailed schedule that includes a narrative, cost and man-loading
curves developed using the critical path method (CPM). In general no individual
activity should have duration greater than 18 working days, where the
contractor believes an activity need to exceed this limit it should be noted
along with a rationale in the accompanying narrative.
This Schedule
represents the contractor’s plan for the works from the date of award. The
baseline schedule shall be used to make the first progress schedule. Once the
baseline schedule is accepted by the PMO, it is to be frozen and shall not be
revised without the PMO’s consent.
Work Breakdown Structure (WBS)
The contractor
shall propose, prior to the submission of the Baseline Schedule a Work
Breakdown Structure (WBS) that integrates with the latest version of Agency
WBS. This WBS shall be provided to contractor, by PMO upon award of
construction contract, additional levels are to be added by contractor to
enable a sensible breakdown into sub areas of work and of responsibility.
Each activity
in the Baseline Schedule shall have a WBS encoded to it.
Activity Coding
In addition to
and separate from the WBS coding, each activity shall be coded to show, as a
minimum:
·
The Phase of work (design, procurement,
construction, etc.)
·
The Party responsible for the work (contractor,
subcontractor, Resident Engineer, External
Agency etc .)
·
The physical location of the work (area, level
etc.)
