CPM construction scheduling services
MASONORA’s construction scheduling service builds and maintains critical path method (CPM) schedules in Primavera P6 or Microsoft Project. We prepare baseline schedules from measured quantities, update them against progress, produce look-ahead schedules for the site team, resource- and cost-load activities where required, and analyze delays when events affect the critical path.

What makes a schedule reliable?
A reliable schedule has realistic durations, complete logic and no artificial constraints holding dates in place. We base durations on measured quantities and stated production rates, so a 40-day slab cycle can be traced back to the slab area and crew output. Every activity has a predecessor and successor, and constraints are only used where the contract requires them.
We run standard schedule quality checks for missing logic, excessive float, negative lags and hard constraints before a baseline is issued.
How often should a schedule be updated?
Most contracts require monthly updates. Each update records actual dates and remaining durations, recalculates the critical path and compares it with the baseline. Between updates, short look-ahead schedules give the site team a practical three- or six-week plan.
Can you analyze delays?
Yes. When an event such as a late design change or a late approval affects the work, we model it in the schedule to show its effect on the critical path and completion date. That time-impact analysis supports extension of time requests. If a dispute moves toward formal proceedings, an independent delay expert is usually appointed, and we will tell you when that point is reached.
What is the difference between a baseline and an update?
The baseline is the approved plan the project is measured against, and it is frozen once accepted. Each update is a copy of the live schedule with actual progress recorded and remaining work re-forecast. Comparing the two shows which activities have slipped, which have gained, and whether the critical path has moved to a different chain of work. Keeping the baseline untouched is what makes that comparison, and any later delay analysis, credible.
Finding the critical path
An illustrative four-activity network showing how early dates and float identify the critical path. Durations are in working days.
| ACTIVITY | DEPENDS ON | DURATION | EARLY FINISH / FLOAT |
|---|---|---|---|
| A. Foundations | Start | 15 | Day 15 / 0 (critical) |
| B. Frame | A | 30 | Day 45 / 0 (critical) |
| C. Underground services | A | 10 | Day 25 / 20 |
| D. Slab on grade | B and C | 8 | Day 53 / 0 (critical) |
| Critical path | A → B → D | 53 | Project finish Day 53 |
What affects the fee and delivery date
We quote every project on its scope, so there is no price list. These are the factors a specialist looks at before confirming a fixed fee and delivery date in writing.
Project size
More activities and areas mean longer schedule development.
Update frequency
Monthly, fortnightly or weekly updates change the ongoing fee.
Loading required
Resource and cost loading add data and reporting.
Contract requirements
Specified formats, narratives and checks add work.

Do you use Primavera P6 or MS Project?
Both. We build in whichever your contract or client requires and deliver native XER or MPP files.
Can you take over an existing schedule?
Yes. We review it for logic and quality, fix issues with your agreement, then maintain it through regular updates.
Do you provide resource-loaded schedules?
Yes. Activities can be loaded with labor, equipment or cost to produce histograms and cash-flow curves.
Can you prepare a delay claim?
We prepare time-impact analyses and supporting schedule records. Formal disputes may need a specialist delay expert.
How is scheduling priced?
A fixed fee for the baseline and a monthly fee for updates are typical. A specialist confirms the structure on your quote.
