  • Pre-submission DCMA QC, so it passes the first time
  • Monthly updates, variance narratives, and look-aheads
  • Time extension requests and TIAs, done right

Peter T. Sheridan

Founder & Principal Consultant
CCM · CMAA PSP · AACE JD · Multiple CALI Awards B.S. CSM · Clemson

Peter's career runs from the deck of a concrete pour to the witness table. He came up through the field as a superintendent on ground-up multifamily work and a project manager on the adaptive reuse of a historic mill, then spent more than a decade managing and scheduling federal and institutional construction on both the owner's and the contractor's side of the table.

That record includes senior project management on the $300M new U.S. Courthouse in Chattanooga, the $165M Jonas Federal Courthouse delivered under budget and ahead of schedule, the master schedule for the $112M Holloway Courthouse, the $65M Madawaska Land Port of Entry kept reliable through Maine winters, and the systems renewal of the historic U.S. Custom House in Charleston. On campus, he provided owner's schedule controls for Cal Poly Humboldt's $192M student housing and program leadership across Gavilan College's $248M capital program.

He pairs that record with credentials few schedulers carry: CCM, PSP, and a Juris Doctor. The result is analysis that is technically rigorous, contractually grounded, and delivered in plain English: a baseline you can trust, an update that gives real warning, a delay analysis that holds up, and exhibits a board can follow.

The best schedule is not the one with the most activities. It is the one that explains how the project will be built, shows what drives completion, and gives the team enough warning to act before a problem becomes a delay.

Delay Advisory

When the delay becomes a claim.

Schedules are where entitlement is won or lost. Hartwell reconstructs what actually happened, ties each impact to the contract, and builds analysis clear enough to move a settlement and rigorous enough to survive an opposing expert.

Method

Windows & Time Impact Analysis

Contemporaneous, method-driven analysis, not hindsight storytelling.

Record

As-Planned vs. As-Built

A defensible as-built reconstruction from the project record.

Cause

Causation & Concurrency

Isolating owner, contractor, and excusable delay, including concurrent impacts.

Support

Fragnet & Expert Exhibits

Fragnets, narratives, and graphics built for negotiation, mediation, and court.

The gold bars are the story: EWP1 releases construction scope in May 2026, almost two years before the full CD set completes. Design workdays grow from 184 to 240, and the project still starts sooner.
How Engagements Work

Three ways to bring Hartwell in.

Scoped in a 20-minute call. Project-based or monthly. No long-term commitment required to start.

01 · One-Time

Independent Schedule Review

A second set of eyes before the schedule goes out, or after it comes back rejected.

  • DCMA 14-point health check with fixes
  • Spec-compliance review (VA / GSA / USACE)
  • Logic, float, and longest-path analysis
  • Written findings memo
Fits: baseline submissions, owner reviews, QC before the claim window closes.
02 · Monthly

Embedded Scheduling Support

Senior-level scheduling capacity without hiring a full-time scheduler.

  • Baseline development or maintenance
  • Monthly updates and variance narratives
  • Executive dashboards and look-aheads
  • Direct support to your PM and super
Fits: overloaded internal schedulers, mid-size GCs, demanding federal specs.
03 · As-Needed

Delay & Claim Support

Analysis rigorous enough to survive an opposing expert, clear enough to move a settlement.

  • Time impact analyses and fragnets
  • As-planned vs. as-built reconstruction
  • Causation and concurrency analysis
  • Recovery schedule development
Fits: contractors, owners, and counsel with time and money on the line.

Common Questions

Before you call.

How fast can you turn a schedule review?
A standard health check and findings memo typically turns in 3 to 5 business days from receiving the XER. Compressed submittal deadlines are common on federal work; if you are up against one, say so and we will scope to the date.
How does pricing work?
Project-based for reviews and delay analyses, monthly for embedded scheduling support. Every engagement is scoped in a 20-minute call before anything is billed, so you know the number before you commit.
Can you work in our P6 environment and templates?
Yes. Work can be done in your P6 instance, to your layouts, activity codes, and WBS conventions, or delivered as XER files ready to import. Deliverables match whatever format your owner requires.
We already have schedulers. Where do you fit?
Most capable contractors do. Hartwell is not a replacement for your team; it is surge capacity and a specialist's eye, an independent QC pass before a submission, a recovery schedule when the team is heads-down building, or a TIA prepared while your scheduler keeps the update cycle running.
Do you support disputes and litigation?
Yes. Forensic schedule analysis, chronologies, TIAs, and exhibits prepared for negotiation, mediation, and litigation support, with the documentation discipline those settings demand. Hartwell is a scheduling consultancy, not a law firm, and does not provide legal advice.
What do you need from us to start?
Usually just the current XER (or the baseline and latest update), the scheduling specification, and 20 minutes with whoever owns the schedule. For delay work, add the relevant notices and the monthly narratives if they exist.
