CPM Scheduling Services in Primavera P6 and Microsoft Project

CPM Project Scheduling uses the critical path method (CPM) to model activities, durations and logic so the project's longest path, float and milestones are visible and manageable.

We build logic-driven CPM schedules linked to the cost estimate so durations, resources and procurement lead times all agree. Schedules are prepared to the contract's scheduling specification where one applies.

What a CPM schedule includes

• Work breakdown structure (WBS) and activity list from the estimate
• Logic ties (finish-to-start, start-to-start, finish-to-finish) with lags and constraints
• Calendars, durations, resources and cost loading
• Procurement, submittal, fabrication and delivery activities
• Milestones, substantial completion and critical-path analysis

Look-aheads, updates and narratives

We produce two- and three-week look-ahead schedules, monthly schedule updates and a schedule narrative that explains progress, delays and recovery. Updates preserve the baseline so changes can be compared.

Delay and time-impact analysis

When delays occur we can prepare time-impact analyses based on the schedule record. This is analysis support, not legal advice.

What you receive

• Baseline CPM schedule (XER, MPP or PDF)
• Look-ahead schedules
• Schedule updates and narrative
• Critical-path and float reports
• Cost- and resource-loaded schedule on request

Technical scope and terminology we work with

• Critical path, total float, free float and near-critical paths
• Finish-to-start, start-to-start, finish-to-finish, lags and constraints
• Baseline, progress update, data date and recovery schedule
• Resource loading, cost loading and earned value basics
• Time-impact analysis and schedule narratives
• Primavera P6 (XER), Microsoft Project (MPP)

Who this service is for

General contractors, construction managers, subcontractors and owners who need a defensible schedule.

How it works

1. Send drawings, specifications, the estimate and contract scheduling requirements.
2. We confirm scope and deliverables.
3. We build the baseline and review it with you.
4. We update the schedule on the agreed cycle.

Software, standards and file formats

We work in PlanSwift and Bluebeam Revu for digital takeoff and markup, Excel and RSMeans-style cost data for pricing, Oracle Primavera P6 and Microsoft Project for scheduling, and AutoCAD-compatible formats for drawings. Deliverables are provided as Excel, PDF and, where relevant, DWG files, organized by CSI MasterFormat.

When to use this service

Use cpm project scheduling when a bid date is close, when your team is stretched across projects, when you need an independent check of your own numbers or drawings, or when you want consistent deliverables in the same format every time. Tell us the due date when you request a quote so the schedule can be planned around it.

Engagement options

• One project: order cpm project scheduling for a single bid or job and receive a firm price and turnaround before we start.
• Several trades or divisions: combine this service with related scopes so quantities, drawings and pricing agree.
• Bid-season capacity: send multiple projects with their due dates and we schedule the work to hit each one.
• Ongoing support: repeat-volume contractors can agree standard formats, cost codes and turnaround so every delivery drops straight into their process.

Quality control, confidentiality and communication

Every deliverable is reviewed by a second team member before it reaches you, and assumptions, inclusions and exclusions are written down so they can be checked. If information is missing we send a short list of questions rather than guessing, and we tell you which assumption we used when a question cannot be answered in time. Your plans, specifications and files are used only to prepare your project work and are not shared publicly; see our privacy policy.

Why contractors outsource CPM scheduling

Bid season and permit queues compress the time your team has for each project. Outsourcing CPM scheduling adds capacity without adding permanent overhead, speeds up turnaround and gives you an independent check on your own numbers and drawings. You stay in control: you review the output, adjust assumptions and make the final decisions.

How the schedule is built

1. Define the work breakdown: phases, areas and trades from the estimate and drawings.
2. Create activities and durations: from quantities and productivity, not guesses.
3. Link logic: predecessors and successors, lags, constraints and calendars.
4. Add procurement and submittals: shop drawings, review times, fabrication and delivery.
5. Load resources and cost: optional, for cash-flow and resource leveling.
6. Analyze: critical path, float and milestone dates; adjust to meet the contract completion date.

Updates and look-aheads

Progress updates record actual starts, finishes and remaining durations at each data date and compare to the baseline. Look-ahead schedules turn the master schedule into short-interval plans for the field. Schedule narratives explain progress, delays and recovery plans. Link with cost control and estimating.
