CPM scheduling separates real project planning from optimistic timelines. A defensible CPM network forces the team to think through dependencies, durations, and constraints in a way that holds up under pressure. Without it, the project schedule is a collection of activities, not a plan.
The contractors who use CPM well win more bids, defend more delay claims, and make better mobilization decisions. The ones who don't either don't have the in-house scheduling depth or have it pulled across too many projects to do CPM development well on any one of them.
AEdigo gives general contractors, subcontractors, owners, and project management firms on-demand access to pre-vetted schedulers fluent in Primavera P6 and Microsoft Project. They build CPM networks from the ground up, working inside your project's contract structure, your office's coding standards, and the level of detail the work requires.
What CPM schedule development services actually deliver
The output is a defensible CPM network with logic that holds up under owner review, claims analysis, or court testimony if it ever comes to that.
Typical outputs from a CPM scheduler working through AEdigo:
Activity development and coding to your office's standards
Logic relationships including FS, SS, FF, SF with documented constraints
Duration development based on production rates and crew sizing
Resource loading where the contract requires it
Calendar setup including weather, holidays, and shift conventions
Critical path identification and float analysis
Schedule narrative documenting basis of schedule and assumptions
Owner submission package per contract requirements
When you actually need CPM development support
A new project requires a CPM schedule for owner submission and your in-house team is committed.
An existing schedule needs to be rebuilt from scratch because the original logic doesn't hold up.
A contract requires resource-loaded CPM and your team isn't fluent in the methodology.
A claims defense requires a CPM network rebuilt to support the analysis.
An owner has imposed a contract format your team isn't familiar with.
Multiple projects are in startup simultaneously and need CPM development in parallel.
A baseline submission was rejected and you need a clean re-submission.
How AEdigo runs CPM development work
1. Match against project type and contract requirements
The match accounts for project type, software, and contract-specific scheduling requirements.
2. Kick-off on coding and methodology
Activity coding structure, calendar setup, resource loading methodology if required, schedule narrative format, and contract submission requirements. The kick-off locks the methodology before development begins.
3. Development
Activity development, logic relationship building, duration assignment, calendar application, and critical path identification. Each component gets documented as it's built, so the schedule narrative writes itself rather than being assembled at the end.
4. Internal QA pass
Before owner submission, the schedule goes through self-review for logic gaps, dangling activities, broken constraints, missing predecessors, and other QA failures that would generate review comments.
5. Submission and revision support
The schedule gets prepared in the contract's required submission format. Revision rounds against owner comments are part of standard scope.
Tools CPM schedulers work in
Primavera P6 for primary CPM development
Microsoft Project for MS Project-led teams
Asta Powerproject for Asta-driven projects
Phoenix Project Manager for niche workflows
Excel for activity development and reporting integration
Schedule QA tools (e.g., Acumen Fuse) for logic verification
What separates a CPM scheduler from a P6 user
Anyone can populate activities and dependencies in P6. The scheduler who delivers a defensible CPM network knows the construction logic, the contract requirements, and the documentation discipline that makes the schedule survive review.
AEdigo vets CPM schedulers on:
P6 or MS Project fluency at production level
Construction logic understanding across project types
Duration development and production rate experience
Resource loading methodology
Calendar and constraint discipline
Schedule narrative writing skill
Contract submission experience across major forms
QA discipline for logic gaps and dangling activities
Use cases by stakeholder
General contractors
Baseline CPM development for new projects
Schedule rebuild on projects with broken or rejected baselines
Claims defense schedule development
Owner submission preparation
Subcontractors
Trade-specific CPM development for self-perform scopes
Production scheduling for trade-internal use
GC schedule integration support
Owners and program managers
Independent CPM development for owner-side review
Claims-stage schedule analysis
Multi-project portfolio scheduling
Common CPM development failures
CPM submissions get rejected for predictable reasons. If your past submissions have hit any of these, the issue is process, not effort.
Logic gaps including dangling activities and missing predecessors.
Constraints used in place of logic, distorting the critical path.
Durations developed without production rate or crew sizing basis.
Calendar setup inconsistent with the project's actual working pattern.
Resource loading missing or inconsistent where the contract requires it.
Schedule narrative incomplete, leaving the schedule undefendable in review.
QA pass skipped, generating predictable owner review comments.
What survives owner review on first submission
Baseline submissions that survive owner review on first pass share predictable characteristics. The ones that get rejected and require multiple cycles also share predictable characteristics.
What separates a clean first-pass submission from one that bounces:
These habits don't require special tools or new processes. They require consistent calendar attention and someone whose role is dedicated to the work, not someone for whom this is an extra responsibility on top of project management or field operations. That's the difference between a workflow that runs cleanly and one that has to be rescued at closeout.
Activity coding matches the contract specification exactly, not approximately.
Logic relationships have documented basis, not assumed predecessor patterns.
Constraints are used sparingly and intentionally, not as substitutes for missing logic.
Durations have production rate and crew sizing basis documented in the narrative.
Calendar setup matches the project's actual working pattern, including weather and holidays.
Resource loading aligns to the contract's required methodology where applicable.
Schedule narrative documents basis-of-schedule with enough depth to defend under review.
QA pass catches dangling activities, broken constraints, and logic gaps before submission.
CPM development services vs. the alternatives
The alternatives are: have the in-house scheduler build CPM between active project updates, contract to a freelance scheduler without project context, or use a generic template adapted to the project.
In-house schedulers stretched between development and updates usually deliver one badly. The CPM development gets rushed, and the logic suffers.
Freelance schedulers without project context produce networks that look complete and miss the construction logic that holds up under review.
Generic templates adapted to specific projects produce schedules that don't reflect the actual logic and don't defend under scrutiny.
AEdigo runs CPM development as a managed engagement: vetted schedulers, your contract requirements, your office's coding standards, with internal QA and submission coverage.

Frequently asked questions
Implementation note: Wrap this section in FAQPage schema markup (schema.org/FAQPage) to qualify for rich results in Google.
Will the CPM schedule meet our specific contract format requirements?
Yes. The match process and kick-off both account for contract-specific submission requirements, including activity coding standards, calendar requirements, resource loading methodology, and schedule narrative format.
Can the scheduler build resource-loaded CPM networks?
Yes. Resource loading is part of standard scope on engagements where the contract requires it. Methodology aligns to the contract specification, not a generic approach.
Does the scheduler provide schedule narrative documentation?
Yes. Schedule narrative documenting basis of schedule, assumptions, durations, and logic decisions is part of standard scope. Without narrative, the CPM doesn't survive review.
Can the scheduler handle owner review comment cycles?
Yes. Comment response and revision rounds are part of standard scope on engagements that include owner submission.
