An assessment that hides its working is not worth much, and neither is a price you have to ask for. Three ways to work with us, from an hour of someone's time to a licence for your own engineers.
They are not tiers. A plant that needs one hour should buy one hour, and a plant that will run this work every month should never be buying studies one at a time.
A question, a review, a second opinion, a specification someone has to write. Billed for the time it takes and nothing else.
$250 an hour · $1,900 a day
The full picture of one plant or one unit: a visit, your own data, and a report your engineers get to argue with. Five steps, one price.
$8,500 remote · $16,500 with a visit
You already know the question. Send the export and get the report. Start with a free evaluation of your own data.
Free to start · $3,500 a study
All figures in US dollars, per site, held to the end of 2027. Travel and accommodation are at cost and agreed before anything is booked. Time spent scoping and quoting is never billed.
Thirty-five years of process control, available in whatever size you need it. No minimum engagement and no retainer.
| Hour | $250 | 2-hour minimum. Remote. |
|---|---|---|
| Day | $1,900 | Eight hours, on site or remote. Travel days at half rate. |
| Week | $8,500 | Five consecutive days, booked in advance. |
Implementation is quoted, not billed hourly. Coding, configuration and commissioning run against a written scope with a fixed price, because open-ended hours on a project nobody has bounded is how consultancy gets its reputation. See how an engagement runs.
The complete look at one plant or one unit. You collect the data, because your people know where it lives; we do everything else and then hand it to your engineers to pull apart.
What are you trying to settle, and does the data that would settle it exist? Some questions the historian can answer and some it cannot. Finding that out costs one conversation rather than one month.
Walk the units, read the control narratives, and talk to the people who run it at three in the morning. This is where you learn the things the data cannot tell you, including which numbers nobody trusts. Omitted in the remote version.
Your people pull the export, because they have the historian access and we should not. We review it the day it arrives, so a bad export is caught in days rather than after the analysis is written.
Every tool that fits the question, run on your data: plant assessment, batch assessment, control loops, or more than one of them. A report at every step, so each number traces back to the file you sent.
Your engineers challenge the findings. This is the point of showing the working, and a finding that dies here has saved you the cost of acting on it. What survives goes into the ranked list, with what we set aside and why.
| Remote assessment | $8,500 | Steps 1, 3, 4 and 5. Right when the question is already clear and the plant is documented. |
|---|---|---|
| With a 3-day plant visit | $16,500 | All five steps, plus travel at cost. Right for a first engagement, or a plant nobody has looked at from the outside in years. |
What comes out of it. A ranked list of what is worth acting on, what was set aside and why, the questions your operators need to answer, and every report behind it. If the outcome is a project, the proposal for that project is quoted separately, against a scope you have already read.
No visit, no meetings you did not ask for. Start with the free evaluation of your own data and decide from there.
One dataset, one report, so you can judge the work before you pay for any of it.
Up to 200 tags, 5 to 7 days of one minute snapshot data
A scoped assessment on your data, plus an hour with your engineers to argue with the result.
Per study · add-ons below
The programs and the work process, running on your own machines, on data that never leaves your site.
One site · then $3,600 a year
Each tool counts a different thing, because each one reads the data a different way. One study is one of the rows below.
| Included in $3,500 | Beyond that | |
|---|---|---|
| IPA — plant assessment | Up to 200 tags, up to 4 weeks at one minute | $900 per further 100 tags |
| BPA — batch assessment | Up to 100 batches of one product | $1,200 per further 50 batches |
| CLA — control loops | Up to 60 loops, PV, setpoint and output | $1,200 per further 30 loops |
Two tools on the same plant is two studies, less 20% when they are run together, because the data preparation is done once.
A worked number. The control loop study in the worked examples looked at 70 loops on a real plant. The old way of counting put 34 loops below par. The analysis found that 3 were genuinely fixable at the loop and 11 more were passing on the same two upstream problems — so the work is two fixes and three loops, not thirty-four projects. Knowing which is which is what the study is for.
An NDA before anything moves, if you want one. Your export is used for your study and nothing else. It is deleted on request once the report is delivered, and it is never used as an example on this site without your written agreement.
Assessments and studies are priced before the data arrives, from the tag list. If the scope turns out larger, we tell you before doing the work, not after.
Some questions the historian genuinely cannot settle — too few samples for the number of tags, or a window shorter than the plant's own slowest cycle. If we find that, we say so and tell you what to ask for. You are not billed for a study that cannot be trusted.
Implementation, coding and commissioning are quoted against a written scope, not billed by the hour. The tools do not connect to your control system, so none of this puts anything on a live plant.
About the free evaluation. 5 to 7 days of one minute snapshot data is the shortest window we have measured as usable, and it holds when the plant's slowest cycle runs in under about a day. Seven days is where our own measurements settle; five works when the cycles are fast. Snapshot rather than averaged, because averaging hides the oscillation we are looking for. If your plant is slower, send more and the report is still free; the report itself always states whether the window was long enough to judge against.
Send a tag list and a few days of export. You get the whole report, and you decide from there.
