How this site is funded, sourced and corrected
Short answer: flat-fee sponsorships that are always labelled, figures that always carry a source and a date, and no arrangement anywhere in this business that pays us per lead or per project.
Independence
BuildingCapEx exists because the useful numbers in commercial capital planning are scattered across standards documents, trade association publications and licensed datasets, and the sites that aggregate them usually have something to sell you.
We do not sell building work, we do not broker it, and we do not take a share of it. No contractor, manufacturer, consultant or lender pays us a commission on anything sourced through this site, and no such arrangement will be introduced quietly. If it ever changes, it changes here first and it changes visibly.
How we make money
Two ways, both flat fee:
- Sponsorships. A company pays a fixed monthly amount to be associated with a category or a section. Sponsored placements are labelled as sponsored where they appear.
- Directory listings. A company pays a fixed monthly amount to appear in a listing. Listings are labelled, and a paid listing does not rank above an unpaid one on anything other than the criteria stated on the page.
What money does not buy, in any amount:
- A mention inside reference content. Cost pages, service-life pages and planning tools are written without reference to who is paying.
- A recommendation, an endorsement, or a position in a comparison.
- Removal or softening of a figure a sponsor dislikes.
- Access to your contact details. We do not sell, rent or broker them, and there is no per-lead arrangement of any kind.
Sponsors are told this before they pay. Some decline on that basis, which is the mechanism working.
Sourcing
Every cost and service-life figure on this site is a reported range compiled from a third-party published source. It carries the source and the year it was published, next to the figure, on the page.
The sources we draw on are publicly checkable: ASHRAE and NRCA service-life data, ASTM E2018 property condition assessment framing, DOE and EIA building stock data, and published brokerage and municipal research.
Where the most useful data exists only inside a licensed or membership-gated dataset, we do not republish figures we have no right to republish. We describe the method and the direction, and we say which dataset we are describing so you can decide whether to license it yourself.
Four rules govern whether a figure ships at all:
- It has a citable, publicly checkable source.
- It stays a range. We do not average a published range into a single number.
- It is paired with what moves a building toward one end of the range.
- It carries its source, publication year and review date.
A figure that fails any of the four does not get published. We would rather leave a gap on the page than fill it with something we cannot stand behind.
Updates
Every published range is re-checked quarterly. Pages carry an Updated stamp showing when that page was last reviewed, not when it was first written.
When a source issues a revision we update the figure and note what changed. We do not silently swap a number and leave the page looking untouched.
Corrections
If something here is wrong, we want to know, and the fastest way to tell us is info@buildingcapex.com.
Material corrections — anything that would change a planning decision — are made on the page and noted at the foot of it with the date and a plain description of what was wrong. Typos and broken links we just fix.
What we are not
BuildingCapEx publishes planning references. It does not publish professional opinions about your building, and nothing on this site should be treated as one.
Specifically, this site is not:
- A reserve study, a property condition assessment, or a substitute for either.
- An engineering opinion, a specification, or a design document.
- A quote, an estimate, or an appraisal.
- Legal, tax, accounting, insurance or investment advice.
The figures here describe what has been published about commercial building systems in general. They do not describe your building. Use them to arrive at a conversation with an engineer, an assessor or a contractor already knowing the shape of the number and the questions worth asking — and then have that conversation.
Who publishes this
BuildingCapEx is published by Spencer Gasselin LLC. Editorial decisions — what gets covered, what a figure says, and what does not get published — sit with the publisher and are not delegated to sponsors or listed companies.
