Our Sectors
From the tight systems tolerances of a data center to the life-safety complexity of a hospital, our schedulers have built, analyzed, and defended schedules across the most demanding construction environments in the country.
What We Do
From baseline development to forensic delay analysis, our team delivers the full spectrum of CPM scheduling services - with the precision and depth that only comes from doing this, and only this, for three decades.
Services & Pricing
Every engagement is scoped precisely, delivered on time, and built to hold up under owner scrutiny, CM review, or attorney cross-examination.
Owners and Owner's Program Managers pay CPM Pros to review the contractor's monthly P6 schedule update and produce a clear, executive-ready 2–3 page narrative: what activities slipped, which milestones are at risk, where total float eroded, and what the contractor's recovery plan shows — or doesn't.
Each monthly narrative also builds a contemporaneous schedule record — invaluable evidence if the project later heads toward a delay claim or dispute. It is insurance and oversight in a single deliverable, delivered within three business days of each update receipt.
When a GC submits a baseline schedule, owners need to know: is this schedule realistic? Is the critical path defensible? Are there hidden constraints, inflated durations, or logic gaps that could leave the owner exposed in a dispute? CPM Pros delivers an independent third-party review with a DCMA 14-point scoring matrix and written findings.
Ideal for progressive design-build projects where owners want independent technical assurance before accepting a contractor baseline — and for owner’s program managers at national OPM firms who add defensible schedule review as a standard component of their program oversight services.
Construction attorneys and owners hire CPM Pros to quantify delay — who caused it, how much time it added to the schedule, and whether it was excusable, compensable, or concurrent. We perform Time Impact Analysis using fragnet methodology, windows analysis comparing schedule snapshots across the project lifecycle, and as-planned vs. as-built comparisons.
Our direct scheduling experience on underground heavy-rail corridors and aviation capital programs is a direct credential here. Transit and infrastructure claims are among the most complex in construction — involving multiple prime contractors, owner-furnished equipment, phased occupancy, and years of schedule updates that must be traced and interpreted.
A GC pursuing a design-build or negotiated project knows their schedule exhibit is scored — and that a polished, logic-driven P6 Gantt signals operational credibility that a hand-drawn bar chart never will. CPM Pros builds proposal-ready schedule exhibits: a compliant P6 XER, a full-color Gantt formatted to the RFP requirements, a written schedule narrative, and a milestone compliance matrix aligned to the owner's required dates.
We've built these for complex proposals — transit, hospital, higher education, federal. Turnaround is fast because we read the spec and understand what evaluators are scoring before we write the first activity.
Service 01 — Deep Dive
Owners and OPMs are stewards of complex, high-stakes programs — with stakeholders, budgets, and schedules to manage at the strategic level. The monthly narrative retainer gives your team a dedicated technical read on every contractor P6 update: float movement, critical path integrity, constraint audits, and milestone risk — surfaced clearly so you stay focused on program leadership while we scrutinize the schedule detail on your behalf.

Clients We Serve
From hyperscale data center owners to construction attorneys building a delay case, each client type we work with brings a distinct schedule challenge — and engages CPM Pros for the specific technical depth that fits it.
Hyperscale data center programs move at exceptional pace. CPM Pros provides the P6 specialist layer — independent schedule oversight, monthly narrative reporting, and rapid peer review — giving in-house teams a dedicated technical partner without standing up a full-time scheduler role.
Manage construction on behalf of owners. CPM Pros schedule review and narrative reporting strengthens the OPM’s offering with defensible P6 expertise — the independent technical eye that a program management team rarely carries in-house.
Construction litigation demands a scheduling expert who can read an XER file, reconstruct a critical path from 50 schedule updates, and explain CPM methodology to a judge or arbitrator in plain English. We deliver the expert report — and the testimony — that the case demands.
Large capital programs with federal oversight requirements. Independent peer review and forensic support for complex, multi-contractor infrastructure schedules.
Focus proposal time on strategy, teaming, and pricing — and engage CPM Pros for the specialist P6 exhibit component so internal teams stay on their highest-value work.
Project Background
Hyperscale data center programs produce the most procurement-constrained, RFS-driven schedules in the industry — medium-voltage switchgear, generators, UPS, transformers, and cooling plant that ship a year or more after PO; thousands of activities disaggregated by trade and equipment unit; phased building energization; and years of monthly updates that have to stay traceable and defensible against a signed baseline. Hospital and transit programs hit the same complexity from different angles: multi-contractor coordination, phased occupancy, owner-furnished equipment, and defensibility under federal or accreditation oversight.
CPM Pros’s direct scheduling work covers hyperscale data center campuses sequenced across multiple buildings, cGMP pharmaceutical and hospital programs, and underground heavy-rail corridors with multi-station expansions and integrated airport systems. The same discipline carries every job: activity-level traceability against the baseline, honest float, and a schedule narrative the owner can put in front of their board, their lenders, or their oversight agency.
For Construction Attorneys
Construction litigation needs a scheduling expert who can read an XER file, trace 50 schedule updates, and explain critical path methodology to a judge in plain English. CPM Pros brings that exact skill set to your delay claims, forensic analyses, and expert witness engagements.
CPM Pros produces court-ready schedule expert reports that document methodology, trace schedule history from baseline through each monthly update, and quantify delay using accepted forensic methods — Time Impact Analysis, windows analysis, and as-built critical path reconstruction.
We serve as a consulting expert during discovery and as a testifying expert in arbitration, mediation, or trial. Our transit and hospital project background provides the sector-specific credibility that complex infrastructure claims demand.

Knowledge Base
Practical guidance written for the people who hire scheduling experts — not for schedulers themselves. Each article addresses a specific decision point or risk that comes with engaging P6 expertise.
Most OPMs manage dozens of moving parts on every program — the contractor’s monthly P6 update is one input among many. Here are the five P6 indicators that surface schedule manipulation, unrealistic recovery, and hidden delay risk at a glance, before they become disputes.
The forensic schedule method you use determines what your expert can prove — and how easily opposing counsel can challenge it. This guide explains the four accepted methods, when each is appropriate, and what contemporaneous documentation you need for each approach to hold up in arbitration.
On progressive design-build and CMAR proposals, the schedule is a technical differentiator — not a formality. Owner evaluators look for five specific things in a bid schedule that signal whether a GC truly understands the project. Here's what they are, and how to score full marks.
Major transit authorities managing multi-billion-dollar capital programs rely on contractor-submitted P6 schedules that shape every lender draw, board report, and delay claim. Here's why independent peer review is becoming a standard procurement requirement — and what a good reviewer delivers.
The DCMA check is now used far beyond federal projects. Most contractor schedules miss at least six of the 14 points at first submission — often because schedulers build for planning purposes without realizing the same file will be evaluated against DCMA thresholds at baseline acceptance. Here’s exactly what owners should require.
Contractors can manipulate a P6 schedule in ways that look normal in a Gantt but are obvious to an experienced P6 reviewer in the XER. This article covers the five manipulation patterns seen most often — constraint abuse, activity splitting, logic deletion, float hiding, and data date games — and how to find each one.
Most firms treat scheduling as a support function. We built CPM Pros on the conviction that scheduling is the most consequential discipline in construction - and that it deserves specialists, not generalists.
Our team has spent 50 years developing and defending schedules on projects that do not forgive ambiguity: hospitals where a day of delay affects patient care, data centers where downtime costs millions, transit systems serving hundreds of thousands of daily riders.
We work in Primavera P6. We understand float, logic, and contract language. We know when a schedule is honest and when it is not. We have spent careers on this - and only this.
Whether you need a baseline developed, a delay analyzed, or an independent schedule review, we're ready to engage. Scheduling is the only thing on our calendar.
