Critical Path Method Consultants
CPM Pros is a pure-play scheduling consultancy. No general contracting, no project management distractions — just expert CPM scheduling for the world's most demanding construction programs.
Contract-ready baselines. Monthly schedule narrative reports. Independent peer reviews. TIA delay claim support. RFP bid schedules. P6 forensic analysis for litigation. Fast, defensible, and built to hold up under scrutiny — for owners, owner's reps, general contractors, subcontractors, and attorneys.
What We Do
Professional scheduling services, scoped per deliverable from your actual documents — an expedited written quote with a firm number and delivery date, typically within 3 business days. Every engagement is per-project: no long-term contract, no retainer required.
A compliant CPM baseline built in Primavera P6 from your contract documents — realistic durations, clean logic, owner milestones, spec-compliant coding (USACE, DOT, federal, or private). Includes the written basis-of-schedule narrative reviewers look for.
Send us progress each month; we status the P6 schedule, run the QA checks, and deliver the updated XER with a clear 2–3 page narrative aligned to your pay application — the update your contract requires, without hiring a scheduler.
Proposal-ready bid schedules for design-build, CMAR, and negotiated pursuits: a compliant P6 XER, a full-color Gantt formatted to the RFP, a schedule narrative, and a milestone compliance matrix. We read the spec and score sheet first.
The review letter came back with findings. We take the rejected XER and the reviewer's comments, correct logic, constraints, float, and spec compliance, and prepare the resubmittal — plus advice on responding to the reviewer.
When the project falls behind and the owner directs recovery, we isolate the true critical path and develop a credible, executable plan that closes the gap — documented so it protects you instead of committing you to the impossible.
Fragnet and Time Impact Analysis that quantifies delay — who caused it, how much time it added, whether it's excusable or compensable. For time extension requests, REAs, LD defense, and claims. Escalates seamlessly to our forensic and expert witness practice if the dispute grows.
When a change order adds scope or disrupts your sequence, the entitlement lives in the schedule. We review your baseline and monthly updates, isolate the time impact of the added or changed work, and document the day-for-day entitlement your change order proposal needs — so a request for added time and cost holds up with the GC or owner.
Primavera P6 runs $3,000+ per seat before training, and a staff scheduler costs $60,000–$130,000 a year for work most small GCs and subs need a few days a month. We carry the software, the licenses, and the gray hair. You send plans, specs, and progress — you get back the XER, the PDF Gantt, and a narrative written in plain English. You'll work directly with the scheduler doing the work, not a salesperson.
How It Works
The process is the same whether it's a baseline, a bid schedule, or a rescue: send documents, get an expedited written quote — typically within 3 business days — and have a scheduler on it the day you approve.
PDFs, a plan-room link, or a file share — plus the schedule spec section and contract milestones if you have them.
A firm number and a delivery date, in writing. No surprises, no long-term contract.
Thirty minutes on the phone with whoever knows the job, then we build — durations, logic, calendars, milestones, spec-compliant coding.
You get the XER, the Gantt, and the narrative. If the reviewer has comments, we address them — that's included, not extra.
CPM Pros is a pure-play scheduling consultancy — no general contracting, no project management distractions. Our schedulers have spent 50 years building and defending schedules on hyperscale data centers, hospitals, transit corridors, and airports: projects that do not forgive ambiguity.
Owners pay us to review contractor schedules. Attorneys pay us to reconstruct them in litigation. That's exactly why the baseline we build for you gets approved: we know what reviewers look for, because we are the reviewers.
Primavera P6, Microsoft Project, Excel — all delivery formats. Fully remote, nationwide.
For General Contractors & Subcontractors
Contractors usually call when a contract clause, a review letter, or a pay application makes the schedule urgent. Whatever the situation, we've handled it — see our page for GCs or for subcontractors, or pick yours below.
Work can't officially start and progress payments won't process until a compliant CPM baseline is approved. We build it from your plans and specs in about 7 business days — revisions until approved.
Contract-ready baseline →Logic errors, open ends, constraint abuse, spec non-compliance — whatever the review letter says, we fix the XER and prepare the resubmittal in 3–5 business days.
Schedule rescue →Missed or rejected updates mean withheld payments and increased oversight. Send us the job each month; we return the updated P6 file and a clean narrative in 3 business days.
Monthly updates →We isolate the true critical path, build an executable catch-up plan, and document it so the recovery holds up under owner scrutiny — in about 5 business days.
Recovery schedule →Time extensions get denied when they arrive without schedule support. We build the fragnet or TIA that proves your delay — for an extension request, an REA, or LD defense.
Delay & TIA support →A logic-driven P6 Gantt signals operational credibility a bar chart never will — and evaluators score it. Compliant XER, formatted Gantt, narrative, and milestone matrix in 2–3 days.
Bid & RFP schedules →Core Practice · Owners · Owner's Reps · Attorneys
The core of our practice: independent schedule oversight, third-party review, and forensic delay analysis for owners, owner's reps, and construction attorneys — the discipline behind every schedule we build.
Monthly narrative reports on contractor P6 updates, independent third-party baseline reviews with DCMA 14-point scoring, and embedded scheduling support for capital programs — from hyperscale data centers to hospitals and transit.
Monthly narratives →Forensic schedule analysis, TIA and windows analysis, expert reports, and testimony for delay claims in mediation, arbitration, and litigation. We read the XER, reconstruct the critical path across 50 updates, and explain CPM to a judge in plain English.
Forensic & expert witness →Deep sector experience across hyperscale data centers, hospitals and healthcare, aviation, heavy rail and light rail transit, education, and cGMP facilities — the background credential behind every schedule we build.

How scheduling services are priced, the five factors that move a quote, what should always be included, and when outsourcing beats hiring.
Most rejected baselines fail the same seven ways. Here's what the review letter means, what to fix first, and how to resubmit so it passes.
On progressive design-build and CMAR proposals, the schedule is a technical differentiator — not a formality. What evaluators look for, and how to score full marks.
Questions Contractors Ask
We provide professional scheduling services at hourly rates, scoped per deliverable. Send plans and specs and you get an expedited written quote — a firm number and a delivery date — typically within 3 business days. No retainers, no long-term contract. What moves the quote: activity count, phasing, agency spec requirements (USACE/DOT), and resource or cost loading.
No. We build and maintain everything in our own P6 environment and deliver the XER file, PDF Gantt, and narrative. You never buy P6 or learn it. If your contract requires native P6 files, that's exactly what you receive.
Plans, specs (especially the scheduling section), contract milestone dates, and 30 minutes with whoever knows the job. PDFs, a plan-room link, or a file share all work.
Yes — that's our schedule rescue service. Send the rejected XER and the review comments; we correct logic, constraints, and spec compliance and prepare the resubmittal in 3–5 business days — expedited written proposal first, resubmittal support included.
This is the most common call we get. Monthly updates turn in 3 business days; rescues in 3–5. Tell us the pay-app deadline and we work to it.
Document the delay in the schedule now, not at the end of the job. Time extension requests without CPM support get denied, and unrequested extensions are frequently waived. We build the fragnet or TIA that quantifies your delay for an extension request, REA, or LD defense.
No. Everything is per-deliverable or per-project. Monthly update service is month-to-month for the life of your project. Most clients start with a single baseline or bid schedule.
A senior scheduler — the same people who build and defend schedules on hyperscale data centers, hospitals, and transit programs, and who serve as forensic experts when schedules end up in dispute. You talk to the scheduler, not a salesperson.
Attach what you have — plans, specs, the schedule spec section, your XER or MS Project file, the RFP. We'll come back with an expedited written quote and a delivery date — typically within 3 business days. Or skip the form and talk to a scheduler now.
