Change Orders & Time Impact Analysis

When a change order or a delay hits, we measure what it did to your completion date

When a change order or owner-caused delay hits, we fragnet it into your Primavera P6 or Microsoft Project schedule and measure the float loss and critical path shift. Time is documented, cost supported separately. Prospective TIA per AACE RP 52R-06, backed by years of forensic delay work.

Flat fee per analysis. Draft TIA within a few business days of your records. Owner-facing narrative and exhibits included.

Why the TIA matters

Sign a change order without checking the time impact and the time is usually gone

Owners and agencies don't pay for delay you can't prove, and a stack of emails doesn't prove it. Entitlement starts with what the event did to the critical path and float, backed by the contract, notice and records. Model it when the change hits. Reconstruct it a year later and you're negotiating from memory.

01A vague justification gets denied. A critical path fragnet shows how the completion date moved and why
02Only delay to a contract completion milestone earns a time extension. A TIA separates real impact from noise, and your delay from the owner's
03Caught in the monthly update, the impact is documented, not reconstructed

A TIA is only as strong as the baseline and monthly record behind it. We build both: P6 baseline development and monthly updates and narratives.

What is in the TIA

A defensible analysis, not a letter saying you're late

Everything the submission needs.

Fragnet Modeling Network

The fragnet for the change or delay, inserted into your P6 or MS Project schedule at the right point and data date.

Critical Path Impact Entitlement

We measure how the event moves the critical path and the completion date.

Float Loss & Delay Windows Analysis

Float consumption and delay windows quantified against the schedule, not estimated after the fact.

Concurrent Delay Causation

Your delay separated from the owner's and from concurrent causes, so you claim the time you can support.

Owner-Facing Narrative Record

Each delay tied to its cause, date and contractual basis, ready to submit.

Exhibits Proof

Gantt fragnets, delay diagrams and float-loss exhibits a reviewer can follow.

How we run it

Modeled the way it would be defended

Same work we do in disputes, done early so the claim is built right the first time.

01

Pull the records

Baseline, updates, RFIs, change orders, field reports and correspondence: what happened and when.

02

Build the fragnet

We find the delay driver and build the fragnet for the event.

03

Model the impact

We validate the update just before the event, insert the fragnet and measure the shift in milestone dates and float, per AACE RP 52R-06.

04

Establish causation and entitlement

Each delay tied to its cause, date and the contract, concurrent delay separated, and classified as excusable, compensable or neither.

05

Write the narrative and exhibits

Owner-facing narrative and exhibits a reviewer can follow.

06

Deliver and stand behind it

Native file (P6 .xer and .xml, or Microsoft Project .mpp), review PDF, narrative and exhibits. The same record is ready if the change becomes a dispute.

Owner & federal compliant

A TIA built to the agency spec and the contract

On VA, USACE and NAVFAC work, the TIA and REA must follow the contract and the spec. We model the fragnet, quantify entitlement, write the narrative to agency requirements, and keep the schedule NAS compliant with a clean SDEF where required.

TIA FAQ

Change order and TIA questions

What is a time impact analysis, and when do I need one?
A TIA models a delay or change on the critical path to show how it moved the completion date. Get one when the change or owner-caused delay hits, while the record is fresh.
How fast is it, and what does it cost?
Flat fee per analysis. Draft within a few business days of your schedule and delay records, revised until it is submission-ready.
What standard do you follow?
Prospective TIA per AACE RP 52R-06, with fragnet modeling. For a retrospective look, the same contemporaneous record supports a windows or collapsed as-built analysis under RP 29R-03.
Can you separate my delay from the owner's?
Yes. Concurrent delay is where many claims get cut. We test overlapping delays against the controlling path and the contract, so you claim the time you can support.
Will the owner or the agency accept it?
We build it to the contract's requirements, with documented assumptions, schedule runs and supporting records. Acceptance depends on the analysis and the owner's or agency's review.
We are mid-claim and behind. Can you still help?
Yes. We model the impact now, tie it to your record, write the narrative, and support a recovery or look-ahead plan while the claim is pending.

Got a change order or a delay sitting unresolved?

Send the change and your schedule. We quote a flat fee within one business day, then deliver a TIA that measures the time impact, with cost documented separately.
